Abstract
In cervical dystonia, functional MRI (fMRI) evidence indicates changes in several resting state networks, which revert in part following the botulinum neurotoxin A (BoNT) therapy. Recently, the involvement of the cerebellum in dystonia has gained attention. The aim of our study was to compare connectivity between cerebellar subdivisions and the rest of the brain before and after BoNT treatment. Seventeen patients with cervical dystonia indicated for treatment with BoNT were enrolled (14 female, aged 50.2 ± 8.5 years, range 38-63 years). Clinical and fMRI examinations were carried out before and 4 weeks after BoNT injection. Clinical severity was evaluated using TWSTRS. Functional MRI data were acquired on a 1.5 T scanner during 8 min rest. Seed-based functional connectivity analysis was performed using data extracted from atlas-defined cerebellar areas in both datasets. Clinical scores demonstrated satisfactory BoNT effect. After treatment, connectivity decreased between the vermis lobule VIIIa and the left dorsal mesial frontal cortex. Positive correlations between the connectivity differences and the clinical improvement were detected for the right lobule VI, right crus II, vermis VIIIb and the right lobule IX. Our data provide evidence for modulation of cerebello-cortical connectivity resulting from successful treatment by botulinum neurotoxin.

Abstract
Cervical Dystonia (CD) and Parkinson's disease, particularly tremor-dominant motor phenotype (TD-PD), showed a selective deficit of time-based prospective memory (TBPM). The two movement disorders are mainly characterized by dysfunctions of basal-ganglia and prefrontal cortex but it is reported that cerebellum also plays a key role in their pathogenesis. These cerebral structures are specifically involved in TBPM rather than in event-based PM (EBPM), but until now no study directly compared these two components of PM between CD and TD-PD patients. Therefore, the present study aimed at investigating if differences in PM functioning between CD and TD-PD patients might exist and if the type of movement disorder moderated the relationship between deficit of PM and deficit of executive functions and retrospective memory. Thirty TD-PD, 27CD patients and 29 healthy subjects (HCs), matched for demographic features, underwent neuropsychological tests for PM, executive functions, retrospective memory and self-rated questionnaires. The three groups did not differ on neuropsychological variables except for TBPM where TD-PD and CD patients performed worse than HCs; moreover, TD-PD performed worse than CD patients. Moderation analysis indicated that the type of movement disorder moderated the relationship between executive dysfunction and TBPM, but not EBPM. In conclusion, selective deficit of TBPM characterizes both CD and TD-PD but it is associated with executive dysfunction only in TD-PD. It might be possible to speculate that the involvement of the cerebellum, responsible for internal timing processes, could explain the impairment of TBPM in both movement disorders. This issue deserves to be explored in future neuroimaging studies.

Abstract
In monogenetic generalized forms of dystonia, in vitro neurophysiological recordings have demonstrated direct evidence for abnormal plasticity at the level of the cortico-striatal synapse. It is unclear whether similar abnormalities contribute to the pathophysiology of cervical dystonia, the most common type of focal dystonia. We investigated whether abnormal cortico-striatal synaptic plasticity contributes to abnormal reward-learning behavior in patients with focal dystonia. Forty patients and 40 controls performed a reward gain and loss avoidance reversal learning task. Participant's behavior was fitted to a computational model of the basal ganglia incorporating detailed cortico-striatal synaptic learning rules. Model comparisons were performed to assess the ability of four hypothesized receptor specific abnormalities of cortico-striatal long-term potentiation (LTP) and long-term depression (LTD): increased or decreased D1:LTP/LTD and increased or decreased D2: LTP/LTD to explain abnormal behavior in patients. Patients were selectively impaired in the post-reversal phase of the reward task. Individual learning rates in the reward reversal task correlated with the severity of the patient's motor symptoms. A model of the striatum with decreased D2:LTP/ LTD best explained the patient's behavior, suggesting excessive D2 cortico-striatal synaptic depotentiation could underpin biased reward-learning in patients with cervical dystonia. Reversal learning impairment in cervical dystonia may be a behavioral correlate of D2-specific abnormalities in cortico-striatal synaptic plasticity. Reinforcement learning tasks with computational modeling could allow the identification of molecular targets for novel treatments based on their ability to restore normal reward-learning behavior in these patients.

Abstract
BACKGROUND AND PURPOSE One of the most widely studied perceptual measures of sensory dysfunction in dystonia is the temporal discrimination threshold (TDT) (the shortest interval at which subjects can perceive that there are two stimuli rather than one). However the elevated thresholds described may be due to a number of potential mechanisms as current paradigms test not only temporal discrimination but also extraneous sensory and decision-making parameters. In this study two paradigms designed to better quantify temporal processing are presented and a decision-making model is used to assess the influence of decision strategy. METHODS 22 patients with cervical dystonia and 22 age-matched controls completed two tasks (i) temporal resolution (a randomized, automated version of existing TDT paradigms) and (ii) interval discrimination (rating the length of two consecutive intervals). RESULTS In the temporal resolution task patients had delayed (P = 0.021) and more variable (P = 0.013) response times but equivalent discrimination thresholds. Modelling these effects suggested this was due to an increased perceptual decision boundary in dystonia with patients requiring greater evidence before committing to decisions (P = 0.020). Patient performance on the interval discrimination task was normal. CONCLUSIONS Our work suggests that previously observed abnormalities in TDT may not be due to a selective sensory deficit of temporal processing as decision-making itself is abnormal in cervical dystonia.

Abstract
PURPOSE Cervical dystonia (CD) is associated with tremor/jerks (50%) and psychiatric complaints (17-70%). The dopaminergic system has been implicated in the pathophysiology of CD in animal and imaging studies. Dopamine may be related to the motor as well as non-motor symptoms of CD. CD is associated with reduced striatal dopamine D2/3 (D2/3) receptor and increased dopamine transporter (DAT) binding. There are differences in the dopamine system between CD patients with and without jerks/tremor and psychiatric symptoms. METHODS Patients with CD and healthy controls underwent neurological and psychiatric examinations. Striatal DAT and D2/3 receptor binding were assessed using [123I]FP-CIT and [123I]IBZM SPECT, respectively. The ratio of specific striatal to non-specific binding (binding potential; BPND) was the outcome measure. RESULTS Twenty-seven patients with CD and 15 matched controls were included. Nineteen percent of patients fulfilled the criteria for a depression. Striatal DAT BPND was significantly lower in depressed versus non-depressed CD patients. Higher DAT BPND correlated significantly with higher scores on the Unified Myoclonus Rating Scale (UMRS). The striatal D2/3 receptor BPND in CD patients showed a trend towards lower binding compared to controls. The D2/3 BPND was significantly lower in depressed versus non-depressed CD patients. A significant correlation between DAT and D2/3R BPND was found in both in patients and controls. CONCLUSIONS Alterations of striatal DAT and D2/3 receptor binding in CD patients are related mainly to depression. DAT BPND correlates significantly with scores on the UMRS, suggesting a role for dopamine in the pathophysiology of tremor/jerks in CD.

Abstract
Cervical dystonia is focal dystonia characterized by involuntary movement of the neck muscle, which leads to abnormal head posture. It can be accompanied with pain and tremor. In this study, we evaluated the presence of depression and anxiety in patients with cervical dystonia and the influence of dystonia symptoms on the quality of life. Psychiatric symptoms were evaluated by use of the Beck Depression Inventory (BDI-II) and Beck Anxiety Inventory. Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) was used to evaluate the cervical dystonia symptoms. Quality of life was assessed by the craniocervical dystonia questionnaire (CDQ-24) and short form 36 health survey (SF-36). Nineteen patients were analyzed. Most of the patients had mild cervical dystonia (mean TWSTRS 23.89). Depression was present in 42.1 % and anxiety in 57.9 % of the patients. Disability due to cervical dystonia correlated with the occurrence of depression (ρ = 0.534) and anxiety (r = 0.652). Disability was found to significantly influence the stigma, emotional state, pain, daily activity, social life, physical function, and physical and mental disability. Pain influenced some aspects of body pain, physical function, and physical and mental disability. Being associated with disability and pain, cervical dystonia decreases the quality of life in many aspects. Disability also influenced depression and anxiety, which were present in half of study patients. In addition to follow up for cervical dystonia symptoms, patients with cervical dystonia should also be assessed for psychiatric symptoms on routine clinical check-ups. In addition to botulinum toxin, psychopharmaceuticals should be considered as a treatment option in these patients.

Abstract
BACKGROUND Adult-onset primary dystonia is thought to be a purely motor disorder. Nevertheless, several studies provided evidence that sensory and psychiatric disturbances may contribute to the clinical spectrum of of dystonia, whereas evidence supporting cognitive impairment is still limited. METHODS A set of neuropsychological tests was administered to non depressed, non demented patients with cranial-cervical dystonia and healthy control subjects. The test battery included n-Back Task, Wechsler Memory Scale, Trail Making Test version A and B, and Wisconsin Card Sorting Test. RESULTS As compared with healthy control subjects of similar age, sex and socio-economic status, patients with cranial-cervical dystonia showed deficit on working memory functions revealed by n-Back task, impairment of mental control and visual reproduction subtests of Wechsler memory scale, deficit on information processing speed and set-shifting capacity revealed by Trail Making Test A and B. CONCLUSION Patients with cranial-cervical dystonia may have impairment in specific cognitive domains relative to working memory, processing speed, visual motor ability and short term memory. Probably, these deficits are not dependent on the clinical expression of dystonia but might rather reflect the cortical and subcortical changes highlighted by functional and VBM imaging studies in patients with different forms of dystonia.

Abstract
Tourette syndrome (TS) is a neurodevelopmental disorder characterized by early onset motor and vocal tics. TS should be differentiated from various movement disorders. We report the case of a 21 year-old-man who was admitted to our clinic due to treatment resistant cervical dystonia attributed to neuroleptics. During the last five years he had been treated for depressed mood, somatic delusions and aggressive behaviour. He had been given SSRIs and atypical antipsychotics at low doses; six months prior to his admission he had been switched to risperidone. Clinical examination revealed torticollis, motor stereotypies, vocal tics (sniffing, repetition of words), mental koprolalia and obsessive-compulsive symptoms. He complained of repetitive intrusive thoughts of harming his sister and thoughts of a "delusional" nature regarding somatic complaints. The patient was diagnosed as TS and was successfully treated accordingly. The presented case illustrates that TS can mimic other movement disorders. Whether patients with TS are at higher risk of developing dystonia, or tics and dystonia share a common pathophysiological mechanism (dopamine-inhibiting processes are probably involved in both conditions) is still debatable.

Abstract
Parameters of quality of life (QOL) measured with the SF-36 questionnaire were studied in 91 patients with torticollis (ST) treated with botulinum toxin A. A control group comprised 50 subjects without ST. The QOL parameters were lower in patients compared to controls. Effects of age, education and illness severity on QOL were found. The illness duration was inversely correlated with QOL parameters. Disabled patients with ST had lower scores on the psychological domain that indicated the poor social adjustment, higher levels of anxiety and depression in this group. The treatment with botulinum toxin A allows to improve significantly QOL in patients with ST and exerts a positive effect on all QOL parameters, with the best improvement on the physical domain after the first injection and psychological domain after the following ones.

Abstract
The aim of this study was to assess health-related quality of life (HRQoL), using the Short Form Health Survey-36 (SF-36), in 70 cervical dystonia (CD) patients after long-term botulinum toxin (BTX) treatment (median 5.5 years), and to identify factors determining reduced HRQoL. We used combined patient-and physician-based measures to assess both CD severity [Toronto Western Spasmodic Torticollis Rating Scale, (TWSTRS)] and effect of long-term BTX treatment, and the Hospital Anxiety and Depression Scale (HAD) and General Health Questionnaire-30 to assess psychological distress. Mean SF-36 domain scores of the CD patients were reduced by <1 SD compared with age- and gender-matched population samples. High TWSTRS total scores and high HAD-depression (HAD-D) scores were the main factors associated with reduced scores in the physical and mental SF-36 domains, respectively. Patients evaluated to have a 'good effect' of long-term BTX treatment (n = 47), had significantly lower median TWSTRS total score, and a 3x lower frequency of high HAD-D scores, than those evaluated to an 'unsatisfactory effect' (n = 23). In conclusion, most CD patients enjoy a good HRQoL after long-term BTX therapy. Reduced HRQoL was associated with more severe disease and/or depressive symptoms.

Abstract
Deep brain stimulation (DBS) of the globus pallidus pars interna (GPi) is an effective treatment for generalized dystonia. Its role in the management of other types of dystonia is uncertain. Therefore we performed a prospective, single-blind, multicentre study assessing the efficacy and safety of bilateral GPi-DBS in 10 patients with severe, chronic, medication-resistant cervical dystonia. Two blinded neurologists assessed patients before surgery and at 6 and 12 months post-operatively using the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS). The primary outcome measure was the severity subscore (range 0-30, higher scores indicating greater impairment). Secondary outcomes included disability (0 to 30), pain (0 to 40) subscores and total scores of the TWSTRS, Short Form-36 and Beck depression inventory. Swallowing and neuropsychological assessment were also performed at baseline and 12 months. One-way repeated measures analysis of variance was used to analyse the data. The TWSTRS severity score improved from a mean (SD) of 14.7 (4.2) before surgery to 8.4 (4.4) at 12 months post-operatively (P = 0.003). The disability and pain scores improved from 14.9 (3.8) and 26.6 (3.6) before surgery, to 5.4 (7.0) and 9.2 (13.1) at 12 months, respectively (both P < 0.001). General health and physical functioning as well as depression scores improved significantly. Complications were mild and reversible in four patients. Some changes in neuropsychological tests were observed, although these did not impact daily life or employment. Our results support the efficacy and safety of GPi-DBS for the treatment of patients with severe and prolonged cervical dystonia who have failed medical management.

Abstract
The purpose of this study was to analyze the health-related quality of life (HRQL) of patients with cervical dystonia (CD) and the impact of botulinum toxin A (BTX-A) therapy in these patients. The authors recruited 101 patients with CD, all previously treated with BTX-A. Both before and 4 weeks after injection of BTX-A the patients were assessed using the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS), a Visual Analogue Scale for pain (VAS: 0-100%), the Short Form 36 health survey questionnaire (SF-36), and the Montgomery-Asberg Depression Rating Scale (MADRS). A control group of 84 healthy volunteers was also evaluated. The patients? baseline SF-36 scores were worse in all the domains when compared with those of the controls. Depression was found in 47.5% of the patients. Improvements were noticed 4 weeks after the single BTX-A injections in all the SF-36 domains, and in the VAS, TWSTRS and MADRS scores. The TWSTRS results did not correlate with any of the SF-36 subscores. Stepwise backward regression analysis revealed depression as the main predictor of poor HRQL, as well as female sex, poor financial situation, and living alone. On contrary, longer treatment with BTX-A was associated with better scores. Cervical dystonia has a marked impact on HRQL and treatment with BTX-A injections has a beneficial effect, seen both in objective and in subjective measures. Depression in CD patients is a main predictor of worse HRQL.

Abstract
The life-transforming experience of overcoming spasmodic torticollis compelled the author to write the following personal account. The author, who triumphed over this debilitating disease, is now an advocate of holistic nursing practices that motivate patients through a genuine concern for patient well-being, community, and humanity. The author describes her personal experience of grief and the grieving process; the healing effects of crying; and her selection of the complementary and alternative therapies of prayer, music, and massage that became instrumental in finding a pathway to recovery. The story has appealing implications for strategies that utilize these concepts and techniques in clinical practice.

Abstract
A case is described in which a patient with idiopathic cervical dystonia is treated successfully with cognitive-behavioural therapy. It was hypothesised that although the dystonia was organic in origin, it was exacerbated and perpetuated by catastrophic thoughts and abnormal illness beliefs, and that modification of maintaining cognitive and behavioural responses would lead to improvement. Self-report outcome measures were consistent with this hypothesis and improvements were maintained at 6-month follow-up.

Abstract
In a 6-month period, three patients aged 5-11 years were transferred to our tertiary care children's hospital for management of severe complications following adenotonsillectomy. The first patient presented with headaches and lethargy and was found to have a sagittal sinus thrombosis from severe dehydration. The second patient was admitted immediately following an intra-operative oral cavity fire due to electrocautery malfunction. She suffered partial-thickness burns to the buccal mucosa, palate, and lips. The third patient was admitted with torticollis. Grisel's syndrome was initially suspected, but a thorough work up resulted in the diagnosis of a conversion disorder. These cases comprise an interesting cohort of three little-known complications of adenotonsillectomy.

Abstract
We examined the impact of cervical dystonia (CD) and long-term botulinum toxin (BTX) treatment on employment status. Data on employment status at onset of CD, at initiation of BTX treatment, and at evaluation of long-term treatment were obtained from 62 CD patients aged 31-66 years (median, 53 years; 61% females) who had been treated for a median of 5 years (range, 1.5-10 years). The employment rate fell from 84% at the onset of CD to 47% before initiation of BTX treatment. With long-term BTX treatment, 72% of those who worked at the initiation of treatment stayed employed, and 67% of those on sick leave returned to work. A younger age and a higher level of education increased the probability of being employed and avoiding disability benefits. Among those who were younger than 55 years at evaluation of BTX treatment (n = 40), the employment rate increased from 47% to 65% with treatment, and among the male patients, it reached the level of the general population (86%). About half of the 34% who received disability benefits did so already before the BTX treatment was initiated.

Abstract
Patients with cranial and cervical dystonia (CCD) suffer from visible involuntary facial, head, and neck movements. Therefore, the social appearance of patients with CCD may be seriously affected and self-perceived stigma can be a major source of disability. The present study investigated enacted social stigmatization of patients with CCD. In a pilot study, a semantic differential scale for assessment of stigma was constructed and validated. The final scale contained eight items representing personality traits to be rated on a seven-point scale (-3 negative extreme to 3 positive extreme). Short video sequences (15 seconds) of patients with various types of CCD and age- and sex-matched healthy controls were presented to a sample of 80 biology students (mean age, 19.8 +/- 2.3 years). Immediately after presentation of each video sequence, the students were asked to perform stigma ratings. Significant differences between CCD patients and controls were found on all eight items (P < 0.001 for each). CCD patients were rated as less accountable for their actions, less likeable, less trustworthy, less attractive, less self-confident, more odd and different, more reserved, and more piteous than controls. CCD patients are subject to serious prejudice and enacted stigmatization. There is a need for informing the public about the nature and symptoms of this disorder and a need to support patients to cope with stigmatization.

Abstract
OBJECTIVE To investigate whether impaired spatial memory contributes to cognitive deficits in idiopathic cervical dystonia (ICD). METHODS The authors tested 16 untreated patients with ICD and 16 healthy controls with four variants of a classic spatial memory task, in which subjects were requested to recall the locations of 16 toy objects either immediately after their presentation or after an unfilled delay of 10 minutes. By varying the spatial relationship between subject and toy object array, we tested encoding and memory of spatial relationships between subject and toy objects (egocentric tasks) and of spatial relationships between toy objects and environment (allocentric tasks). RESULTS In all four tasks, absolute performance of patients did not differ significantly from controls, suggesting that there are no significant spatial memory deficits in ICD. However, significant correlations between egocentric and allocentric task performance were found in patients but not in controls. CONCLUSIONS While control subjects flexibly used egocentric or allocentric spatial representations in memory tasks, patients with idiopathic cervical dystonia (ICD) solved both task types with a single allocentric strategy. Our findings point to the existence of compensatory mechanisms between distinct neural systems supporting egocentric and allocentric spatial representations in ICD.

Abstract
Neck muscle vibration is known to influence body orientation and posture during locomotion and stance in normal subjects. To verify the hypothesis that neck proprioceptive input can be misinterpreted in patients with cervical dystonia (CD), lateral continuous vibration was applied to the sternocleidomastoid muscle during both stepping-in-place and quiet stance, with eyes closed. The orienting responses of CD patients were compared with those of normal subjects. Vibration effects on body orientation during stepping and stance were apparently different from normal, since no effects were seen when all patients' data collapsed were analysed. However, while some patients did not respond to vibratory stimuli regardless of the vibrated side, others had a 'good' side, the stimulation of which produced effects on body orientation similar to those observed in normal subjects. Homogeneous groups within the patient population were identified, based on the vibration-induced responses under stepping conditions. The different orienting or postural responses observed in CD patients were correlated with disease-related features such as spontaneous head position, maximum range of voluntary head yaw, presence or absence of a botulinum toxin treatment and disease duration. Our data suggest that, in CD patients, the reference system used in the control of body orientation in space is either refractory to the lateralized proprioceptive neck input or modified such that the input from both sides produces an orientation shift in the same sense. This would depend on the pathogenesis of the disease or on an adaptive process connected to the head abnormal posture. It seems that this refractoriness spreads to both sides of the neck with the advancement of the disease, thereby possibly entraining a progressive shift from a reference system based on the head to a more reliable egocentric reference.

Abstract
OBJECTIVE To assess whether alexithymia is a risk factor for exacerbation in spasmodic torticollis (ST). METHODS ST patients (2 x 10) with high vs. low alexithymia scores (mean score on the 20-item Toronto Alexithymia Scale [TAS-20]=69.2 vs. 28.7) were compared on physiological, motor and subjective responses to a cognitive and an emotional laboratory stressor. Changes in sustained abnormal head/shoulder positions and maximum range of motion (ROM) of the cervical spine were kinematically quantified. Skin conductance level (SCL), nonspecific skin conductance fluctuations (NS.SCF), heart rate (HR) and skin temperature (T) were measured. RESULTS High alexithymia had no effect on the abnormal head posture or movements, but high-alexithymic ST patients showed generally increased levels of autonomic arousal (more NS.SCF, higher SCL; analysis of variance [ANOVA]: P=.016 and P=.051, respectively) under all experimental conditions. When ST symptom severity (TSUI-score) was partialled out, these group differences were somewhat reduced (analysis of covariance [ANCOVA]: P=.052 and P=.143). CONCLUSIONS High alexithymia did not lead to increased abnormal head movements to stressors, but may result in a subtle increase in tonic level of sympathetic activity.

Abstract
The most widespread approach to rehabilitation of cervical dystonia is electromyographic (EMG) biofeedback. However, consensus is lacking regarding the true effectiveness of this technique. The aim of this study was to evaluate how cervical dystonia was influenced by two rehabilitative treatments, namely a standard biofeedback program and a novel physiotherapy program consisting of postural reeducation exercises and passive elongation of myofascial cervical structures. Both programs were consecutively administered to 4 patients with cervical dystonia. The study design was a behavioral analysis of single cases. The main outcome measures were a head realignment test, a disability questionnaire and a pain visual analogue scale (VAS). Each patient's performance was evaluated before the study and after the first and second program. Furthermore, the disability questionnaire and the pain VAS were administered 3, 6, and 9 months after the end of the treatments. The physiotherapy program showed therapeutic effects comparable to those of EMG biofeedback. Reductions of disability and of pain were still present 3-9 months after the end of the treatments. These preliminary results suggest that the physiotherapy program proposed in the present study may be a promising method for rehabilitation of cervical dystonia.

Abstract
The purpose of this study was to assess whether alexithymia is a risk factor for autonomic dysregulation in cervical dystonia (spasmodic torticollis, ST). Alexithymia was assessed by an authorized German version of the TAS-20. In a first step, we recruited 10 ST-patients with high alexithymia scores (> 62; M = 69.2, SD = 3.0) and compared them with 10 ST-patients with low alexithymia scores (< 35; M = 28.7, SD = 4.3) on physiological and subjective responses to a cognitive and an emotional laboratory stressor. High-alexithymic ST-patients generally showed increased levels of autonomic arousal (higher SCL, more NS.SCF and lower T; 0.016 </= p </= 0.065) under all experimental conditions. In a second step, we used a less extreme alexithymia-definition (high >/= 57 vs. low </= 36) in a sample of 2 x 20 probands and found no significant differences. Our results suggest a chronically increased level of sympathetic activation in high-alexithymic patients with spasmodic torticollis.

Abstract
The aim of the study was to evaluate and compare health-related quality of life (HR-QoL) and depression in essential blepharospasm (BSP) and idiopathic cervical dystonia (CD), to identify the clinical and demographic factors associated with poor HR-QoL in both disorders and to analyse the effect of Botulinum Toxin A (BtxA) therapy. Two hundred-twenty consecutive patients with BSP (N = 89, 62 % women, mean age 64 years, mean disease duration 7 years) and CD (N = 131, 64 % women, mean age 53 years, mean disease duration 8 years) recruited from routine referrals to eight Austrian dystonia clinics were included. HR-QoL was measured by the Short Form 36 (SF-36) and depression by the Beck Depression Inventory (BDI). At baseline, patients with CD and BSP scored significantly worse in all eight SF-36 domains compared with an age-matched community sample. In addition, 47 % of patients with CD and 37 % of those with BSP were depressed. Women with BSP scored significantly lower in all SF-36 domains and were more depressed than male patients. In contrast, there was no significant effect of gender on HR-QoL and depression in CD. Neck pain had a significant impact on all SF-36 domains and represented the main determinant of depression in CD. Although BtxA therapy resulted in a significant improvement of clinical symptoms in BSP and CD, HR-QoL did not improve in BSP and only two of the eight SF-36 domains improved significantly in patients with CD. The present study for the first time demonstrated that BSP has a substantial impact on health status emphasizing the need for psychological support with interventions aimed at treating depression in these patients. Our results provide further evidence for the profound impact of CD on HR-QoL and indicate the importance of an adequate management of neck pain in addition to reducing the severity of dystonia in CD. The mismatch between objective BtxA derived improvement of dystonia and lack of change of HR-QoL as determined by the SF-36 illustrates the need for optimized disease specific quality of life rating scales in patients with craniocervical dystonia.

Abstract
We studied the effect of cervical dystonia on quality of life in a cohort of 289 patients by using a generic health status measurement scale (SF36). Cervical dystonia had a significant negative impact on quality of life compared with age-matched general population data. This negative impact was comparable to that seen in multiple sclerosis, Parkinson's disease, and stroke.

Abstract
BACKGROUND Little is known about the quality of life in patients with cervical dystonia, although pain and depression are relatively common. OBJECTIVE To test the hypothesis that an individual's ability to cope with the disease will modify the association of intrinsic, extrinsic, and disease related factors with quality of life. METHODS Patients with cervical dystonia diagnosed by a movement disorder specialist were recruited from seven European countries. Data on quality of life (SF-36), measures of coping, and intrinsic, extrinsic, and disease related factors were collected by a self completed postal questionnaire. RESULTS 289 patients (101 men and 188 women), mean age 55 years, completed the questionnaire. Both physical and mental quality of life scores were predicted by self esteem and self deprecation, educational level, employment status, social support, response to botulinum toxin, disease severity, social participation, stigma, acceptance of illness, anxiety, and depression. In multivariable analyses, the strongest predictors were anxiety and depression. Severe depression was associated with a 19.1 point decrement in the physical summary score (95% confidence interval, -31.7 to -6.6; p = 0.003); however, disease duration and severity remained predictors. CONCLUSIONS Care for patients with cervical dystonia must not only focus on reducing the severity of the dystonia but also on the psychological wellbeing of the patient. Interventions aimed at treating depression or anxiety, especially of a cognitive nature, may have a large impact on improving quality of life.

Abstract
The Ekbom's syndrome, also known as delirium of parasitic infestation, acarophobia, delusional parasitosis, psychogenic parasitosis, is a disease of rare occurrence. Generally it is characterized by the firm conviction of the patients to be infected by worms that come out of the skin, usually from the scalp or even from the mouth, from the eyes or from the genital region. Most of the patients are elderly and female, and with frequent social isolation. Some cases are associated with organic diseases as hyperthyroidism, diabetes, cortical lesion, intoxication by medicines. To our knowledge the association between delusional parasitosis with spasmodic torticollis was not described in literature. We report the case of a 72-year-old-woman with delusional parasitosis associated with spasmodic torticollis.

Abstract
OBJECTIVES To study the prevalence of psychiatric comorbidity assessed by the use of a structured clinical interview in a large, representative sample of patients with spasmodic torticollis (ST) and to test the hypothesis that social phobia would be highly prevalent. METHODS In a consecutive cohort of 116 patients with ST treated with botulinum toxin overall psychiatric comorbidity was studied prospectively with the structured clinical interview (SCID) for DSM-IV axis I disorders. Physical disability and psychosocial variables were also assessed with standardised self rating questionnaires. RESULTS 41.3% of the subjects met DSM-IV clinical criteria A-G for current social phobia as the primary psychiatric diagnosis. This figure rose to 56% including secondary and tertiary psychiatric diagnosis. There was no correlation between severity of disease (Tsui score, severity of pain, body image dissatisfaction score) and psychiatric comorbidity. The only significant predictor of psychiatric comorbidity was depressive coping behaviour (logistic regression analysis, p < 0.01; OR=10.8). Compared with a representative sample of the general adult population, in the patients with ST the prevalence of clinically relevant social phobia is 10-fold, of mood disorders 2.4-fold, and of lifetime psychiatric comorbidity 2.6-fold increased. CONCLUSIONS A particularly high prevalence of social phobia was found in the cohort of patients with ST. The finding of a high prevalence of social phobia and depressive coping behaviour as the main predictor of psychiatric comorbidity may make a subgroup of patients with ST particularly amenable to specific psychotherapeutic interventions.

Abstract
Little is known about the "stigmatizing" effects of Spasmodic Torticollis--a condition that produces physical disfigurement. This is important in understanding the social dimensions of this disorder. This study examined the presence, the dimensions, and the degree of perceived stigma in patients with Spasmodic Torticollis. The study was completed in two stages. In the first stage, ten patients were interviewed to identify the effects of their condition on their social interactions. In the second stage, a self-rating measure of stigma and questions about the impact of the condition on the patients' lives were devised. Perceived stigma was defined as avoidance of others, avoidance by others, self-consciousness, feeling unattractive, feeling apologetic, and feeling different from others. The questionnaires were sent to one hundred patients. The majority of the patients perceived "some" or "severe" stigma. Stigma was found to affect the patients' social, private, and working lives. It is suggested that stigma in Spasmodic Torticollis needs to be considered as a parameter relevant to the clinical management of these patients.

Abstract
OBJECTIVE The study investigates individual differences in the mental representation of attachment and their impact on the cortisol response to psychosocial stress in idiopathic spasmodic torticollis (IST). It was hypothesized (a) that in IST insecure attachment is more prevalent than in a non-clinical control group and (b) that subjects with dismissing attachment respond with higher physiological arousal to a specific stimulus activating the attachment behavioural system than subjects with secure attachment. METHOD 20 patients with IST and 20 healthy controls matched for age and sex underwent the Adult Attachment Interview, an hour-long, semiclinical interview on attachment experiences. During the interview salivary cortisol levels were monitored. The subjects' mental state with regard to attachment was classified using the attachment Q-sort method. Anxiety and depression were measured as potential covariates of the adrenocortical stress response. RESULTS Compared to the non-clinical group, dismissing attachment was strongly overrepresented in IST. In IST, but not in the healthy control group, dismissing attachment correlated with an elevated cortisol response to the interview. CONCLUSION In clinical, but not in non-clinical samples dismissing attachment may be associated with increased vulnerability to psychosocial stress. The factors contributing to this interaction are not yet fully elucidated.

Abstract
Injections with botulinum toxin type A (BTX) are considered the first-line treatment for spasmodic torticollis (ST), blepharospasm (BL) and hemifacial spasm (HFS). Because BTX brings only temporary and partial relief, patients frequently try other additional therapies to minimize their symptoms. The subjective rating of all therapies ever tried by patients with ST, BL and HFS was evaluated by using a simple questionnaire. Two hundred questionnaires were considered (112 TS, 54 BL, 34 HFS). BTX was rated subjectively the best therapy in all three diagnostic groups (median: 2 = good effect). Despite Citalopram and physiotherapy (median: 3 = average effect), all other therapies were rated with a median of > or = 4 (= minimal effect). Patients with ST tried 7.7, patients with BL 2.4 and patients with HFS 2.6 different types of therapy. In conclusion, BTX is the most effective treatment for patients with ST, BL and HFS, as rated subjectively. Further evaluation of therapies additional to BTX injections is recommended.

Abstract
We investigated alexithymia and the mental representation of attachment in idiopathic spasmodic torticollis (IST). It was hypothesized a) that alexithymia in IST is more prevalent than in a nonclinical control group and b) that significant correlations emerge between alexithymia and a dismissing attachment representation. Twenty patients with IST and 20 healthy controls matched for age and sex were administered the Toronto Alexithymia Scale (TAS-20) and the Adult Attachment Interview (AAI). Attachment was classified using the Attachment Interview Q-sort. IST patients scored significantly higher on the measure of alexithymia than subjects in the comparison group. In IST a dismissing attachment representation was significantly more frequent than in the control group. Across the total sample, externally oriented thinking correlated positively with dismissing attachment, and both externally oriented thinking and difficulty communicating feelings (two of the three subscales of the TAS-20) correlated inversely with secure attachment. Alexithymia is more prevalent in IST than in normals. As was hypothesized, alexithymia in adults is significantly interrelated with the mental representation of attachment.

Abstract
Vestibular and neck proprioceptive signals are known to be used in judging the locations of objects in space and relative to the body. Given that these signals are asymmetric in patients with spasmodic torticollis, one would expect such patients to have abnormal spatial perception. We tested this idea by measuring patients' perception of visual straight ahead (VSA) under various conditions: with the body in its primary position, i.e. with the head and trunk as closely aligned as possible, and after well defined passive rotations of the head and/or trunk. In the primary body position, patients' VSA direction showed considerable variations which were similar, however, to those of normal subjects; it was independent of torticollis direction, of the head torque it produced, and of the weak spontaneous nystagmus recorded in seven of the 10 patients. After whole-body rotations, i.e. where head and trunk underwent the same motion, the VSA was shifted in both patients and normal subjects, and in both groups the shift was symmetrical after rotations to the right or left. After motions where the trunk rotated under the stationary head (neck proprioceptive stimulation) or the head on the stationary trunk (combined vestibular and neck stimulus), the VSAs of normal subjects coincided rather well with their head midsagittal planes, whereas the VSAs of patients were shifted considerably towards the trunk, again in a symmetrical way. We suggest two mechanisms to explain the findings in patients: (i) a central compensation which restores symmetry of the afferent inflow in the patients (unlike the motor efference); (ii) shifting of the reference for the VSA from the head towards the trunk, because the trunk is a more reliable egocentric reference than the head in the patients. Our findings do not support the assumption that asymmetries in afferent inflow are responsible for the asymmetry of motor output in spasmodic torticollis.

Abstract
Idiopathic spasmodic torticollis (IST) is one of the most frequent dystonic movement disorders. Its classification as a focal dystonia, as well as its treatment with botulinum toxin resulted in groups of patients being regularly seen by neurologic specialists. In a multicentre study, we investigated psychosocial changes, coping and psychopathology, and their interrelations with signs, symptoms and course. 256 patients were included in the study (59.3% women, 40.7% men). The mean age was 49.1 years. Rotating torticollis occurred more often than latero-retrocollis and antero-retrocollis. A family history of IST was seen in 3.1% of the total sample. 34% of the patients had additional dystonic symptoms. Most frequently, these affected the upper extremities (13%), less often the legs. 19.1% of the patients had experienced a period of complete remission. The General Symptom Index of the SCL 90-R in 27% of the patients ranged above the double standard deviation of the normal controls, indicating a clinically significant psychopathology.

Abstract
In this study, idiopathic spasmodic torticollis (ST) has been classfied into three types from the opinion of social adaptation and the differences of frustration tolerance. The three types were as follows: type I (overadaptive type), type II (maladaptive type), and type III (compatible type). Type I is a typical psychosomatic with high frustration tolerance. Type II is personality disorder with low frustration tolerance. In type III, frustration tolerance varies depending on social circumstances (i.e., different at home and at the office). In type I, the prognosis of ST is generally unfavorable, since it is associated with recurrence and prolongation of the symptoms. In type II, the prognosis of ST is generally favorable. However, type II patients experience relationship or social difficulties. One characteristic of type III is that the onset of symptoms is usually found in an older person because of proper use of frustration tolerance at home and at the office.

Abstract
BACKGROUND Spasmodic torticollis is a movement disorder of the nuchal muscles, characterized by tremor or by tonic posturing of the head in a rotated, twisted, or abnormally flexed or extended position or some combination of these positions. The abnormal posturing of the head allows this disorder to be clinically diagnosed. Psychiatric symptoms frequently accompany or precede the diagnosis of the movement disorder. METHODS Using the key words "torticollis," "spasmodic torticollis," "therapy," "behavior therapy," "botulinum toxin," MEDLINE was searched from 1989 to 1996 for information on the cause and treatment of spasmodic torticollis. RESULTS AND CONCLUSIONS Therapies include behavior modification, such as biofeedback, hypnosis, or simply training the patient to consciously readjust the position of the head; pharmacotherapy, using a variety of agents, the most commonly prescribed being anticholinergic medications or the botulinum toxin type A; and surgery, which entails selectively denervating the muscles responsible for the abnormal movement or posture of the head. The most effective treatments include surgery and botulinum, with sustained success rates ranging from approximately 60 to 90 percent.

Abstract
Cervical spinal pain is frequently found in conjunction with idiopathic cervical dystonia (ICD), a focal dystonia characterized by sustained deviation of the head. Since the perception of noxious stimuli has never been studied in ICD, we performed a controlled study to obtain more insight into the psychophysics of dystonia-related muscle pain by evaluating pressure-induced pain levels. In nine ICD patients and five gender- and age-matched asymptomatic control subjects, pain-pressure thresholds (PPTs) were determined in the sternocleidomastoid and upper trapezius muscles, both at resting activity and at maximal voluntary contraction (MVC). The masseter muscles served as non-pathological control regions. To determine the accuracy of PPT values, pain intensity and unpleasantness were rated at threshold on 100-mm visual analogue scales. Four replication measurements were obtained. The data were analyzed by multilevel procedures. For all muscles under investigation, average PPTs of the ICD patients were about two times lower than those of the control subjects (P < 0.001-0.0005) and showed a smaller intra-subject variance. Further, average PPTs at MVC were about two times higher than those at resting activity (P < 0.005). These results provide psychophysical evidence to suggest that, at controlled levels of muscle contraction, the threshold of pain perception is decreased in ICD. In addition, ICD patients seem to be better able to establish their own PPTs than control subjects, which might be due to a different setting of the discriminative aspect of pain in ICD. Surprisingly, lower intensity and unpleasantness scores were found in ICD patients with coinciding painful and deviated sides than in ICD patients for whom the painful side was opposite to the deviated one (P < 0.05). This finding might be of clinical importance for defining functional disability and predicting treatment outcome.

Abstract
We studied visuospatial function in 15 patients with idiopathic spasmodic torticollis (ST) and 15 age- and sex-matched controls. All subjects underwent a battery of visuospatial tests, assessing different functional components of spatial ability. The performance of ST patients on tasks of spatial perception did not significantly differ from that of normal subjects, but patients performed significantly worse on spatial tasks requiring mental manipulation of personal space. This distinct pattern of visuospatial impairment may result from basal ganglia dysfunction.

Abstract
A literature survey was done to outline the natural history of cervical dystonia (spasmodic torticollis). The disorder starts between 25 and 60 years with head deviation or neck pain. Sometimes, there are personal or familial extrapyramidal antecedents (tremor, dystonia). The role of a preceding neck or head trauma is unsettled. Often, there is a delay in diagnosis of more than one year. The majority of patients show steady progression of their focal dystonia and reach maximal disability after five years; neck pain occurring in 70-80% contributes significantly to disability. In a third of the cases, there is a progression to segmental dystonia. In about 20% of the patients a spontaneous, sustained or unsustained remission of the torticollis can be observed; this occurs particularly in cases with earlier age of onset. Cervical dystonia has important psychosocial consequences: many patients have to withdraw from their job or from social activities.

Abstract
The question of subgroups in idiopathic spasmodic torticollis, which has been discussed in earlier studies in order to define etiologically heterogeneous patient populations has lost some of its relevance since with the injection of botulinum toxin an effective treatment is available. However, psychosocial distress is linked with spasmodic torticollis in a substantial number of patients. In order to define criteria for psychosocial interventions in addition to the treatment with botulinum toxin, a cluster analysis was carried out to identify high-risk populations in terms of psychological and social distress. Five subgroups were defined on the basis of eight variables. Two of these five groups, one group with rotational torticollis and one with laterocollis, emerged as particularly distressed by their physical complaints, the effects of their illness on various areas of life and in terms of psychological functioning. The consistency of the subgroups was tested and statistically confirmed by analysis of variance. In a cross-validation 83.02% of the ungrouped cases were predicted correctly. The authors suggest that the evaluation of psychological and social aspects of the condition should be part of the neurological assessment in order to offer appropriate support to patients, who reveal a high degree of psychological distress.

Abstract
In a previous study screening for psychopathological symptoms in a sample of 256 patients with spasmodic torticollis had resulted in 27% of patients, whose mean score of the GSI of the SCL-90-R was above the double standard deviation of the control group of normals (Scheidt et al. 1994). In this study the self-reported psychopathology of a subsample of 19 TS patients was controlled for its agreement with a clinical assessment in a psychiatric interview. The results of the study confirm the validity of the SCL-90-R as a screening instrument for psychological distress and psychopathology. However a tendency for social desirability in a subgroup of patients might lead to underestimate the degree of psychological distress in this patient group and might als account for some of the discrepant findings concerning psychological distress and psychopathology in TS in former studies. Furthermore the clinical assessment revealed a high psychiatric and psychosomatic morbidity prior to the onset of the spasmodic torticollis as well as a high frequency of traumatic life events (e.g. bereavement) in the patients premorbid history. In addition to coping with a crippling neurological condition concurrent psychopathology in TS therefore should be considered also in terms of the individuals premorbid psychological vulnerability.

Abstract
Twenty patients with cervical dystonia were treated during one year with repeated intramuscular injections of botulinum toxin. The outcome was evaluated comparing subjective global rating with relative changes in degree of pain on the Visual analogue scale (VAS), degree of dysfunction due to dystonia, and quality of life according to the Nottingham health profile (NHP). Objective measurement of dystonic position and movement ability was performed using a goniometer, semiquantitatively noted as scores according to Fahn and Tsui. Before treatment, the degree of impaired life quality on the NHP did not correlate with the Tsui score of dystonic posture, but significantly with the Fahn score (p < 0.01) which also includes data on pain. Significant improvement after treatment was seen for all parameters (p < 0.05). Global subjective rating correlated significantly with improved posture according to the Tsui score (p < 0.05), but not with reduced pain or degree of dysfunction. The results suggest that the efficacy of botulinum toxin in cervical dystonia is best evaluated using a combination of the VAS for pain and the Tsui score for dystonic posture and movement ability.

Abstract
Visuospatial functions were studied in 18 patients with spasmodic torticollis and 18 matched controls. Subjects were examined with respect to their judgement of the subjective vertical, personal and extrapersonal orientation, the discrimination of left and right, the ability to judge angles and distances, and a drawing task. Patients showed marked deficits in extrapersonal orientation and atypical displacement errors to the right when requested to set the subjective vertical. Results were largely independent of the clinical characteristics of the disease. The pattern of results was attributed to a subtle attention deficit underlying complex measures of visuospatial functions. This may reflect a discrete dysfunction of the striatal-frontal circuits at least in a subgroup of patients.

Abstract
A multi-adjustable torticollis orthosis is described for the post-operative bracing of patients after surgical correction of congenital muscular torticollis. The orthosis can be put on in the early post-operative period and the head and neck position can be maintained in the corrected, and later over-corrected position by the built-in multi-adjustable joint-mechanism. The details of the manufacturing are described. Twenty-five patients (13 girls and 12 boys) from age 1 to 22 with congenital muscular torticollis were fitted with the orthosis post-operatively for an average duration of 10 weeks. Satisfactory compliance with the orthosis was found in 23 cases. Complications were minimal (3 cases) and were related to scalp irritation which improved after minor adjustments of the halo.

Abstract
A case of spasmodic torticollis is described to demonstrate the clinical usefulness of a new theoretical model of somatic illness and disease. Based on a conception of the living organism as a self-regulating system, the model attributes somatic disorders to a variety of regulatory disturbances including deficits in affect regulation and in the ability to maintain a stable and cohesive self. Throughout the analytical treatment, attention was given to repairing deficits in the patient's self-organisation, and to elevating chaotic impulses and inchoate emotions from a primitive sensorimotor level of experience to a mature representational level where they could be valued for their signal function and modulated through imaginal activity and communication with others. Analysis of the patient's pathologic internal object relations modified his self-organisation, and enabled him to establish regulatory interpersonal relationships that complemented his enhanced self-regulatory capacities. These changes were accompanied by a gradual resolution of the patient's torticollis.
