Abstract
Psychiatric symptoms are an increasingly recognised feature of movement disorders. Recent identification of causative genes and autoantibodies has allowed detailed analysis of aetiologically homogenous subgroups, thereby enabling determination of the spectrum of psychiatric symptoms in these disorders. This review evaluates the incidence and type of psychiatric symptoms encountered in patients with movement disorders. A broad spectrum of psychiatric symptoms was identified across all subtypes of movement disorder, with depression, generalised anxiety disorder and obsessive-compulsive disorder being most common. Psychosis, schizophrenia and attention deficit hyperactivity disorder were also identified, with the psychiatric symptoms often predating onset of the motor disorder. The high incidence of psychiatric symptoms across such a wide range of movement disorders suggests a degree of common or overlapping pathogenic mechanisms. Our review demonstrates the need for increased clinical awareness of such co-morbidities, which should facilitate early neuropsychiatric intervention and allied specialist treatment for patients.

Abstract
Antineuronal autoantibodies are associated with the involuntary movement disorder Sydenham chorea (SC) and paediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) which are characterized by the acute onset of tics and/or obsessive compulsive disorder (OCD). In SC and PANDAS, autoantibodies signal human neuronal cells and activate calcium calmodulin-dependent protein kinase II (CaMKII). Animal models immunized with group A streptococcal antigens demonstrate autoantibodies against dopamine receptors and concomitantly altered behaviours. Human monoclonal antibodies (mAbs) derived from SC target and signal the dopamine D2L (long) receptor (D2R). Antibodies against D2R were elevated over normal levels in SC and acute-onset PANDAS with small choreiform movements, but were not elevated over normal levels in PANDAS-like chronic tics and OCD. The expression of human SC-derived anti-D2R autoantibody V gene in B cells and serum of transgenic mice demonstrated that the human autoantibody targets dopaminergic neurones in the basal ganglia and other types of neurones in the cortex. Here, we review current evidence supporting the hypothesis that antineuronal antibodies, specifically against dopamine receptors, follow streptococcal exposures and may target dopamine receptors and alter central dopamine pathways leading to movement and neuropsychiatric disorders.

Abstract
OBJECTIVE Botulinum toxin (BTX) injections have been used extensively in medicine; however, little is known about the factors predicting the loss of effectiveness of botulin toxin. METHODS Using a clinical database, we identified 401 subjects who had been treated for movement disorders from 1998 through 2010 with onabotulinumtoxin A (BTX A) or who switched from BTX A to rimabotulinumtoxin B (BTX B). We compared patients who switched from type A to type B with patients using type A only with regard to number of visits, total number of injections, number of initial and final sites, number of initial units used, and duration of treatments. RESULTS We observed that patients who switched from BTX A to B had a significantly higher number of initial injection sites than patients with BTX A only (BTX A to B median = 8.5; BTX A median = 6; p for difference = 0.006), had a higher number of final sites (BTX A to B median = 9 BTX A median = 7; p = 0.01), and were also more likely to have multiple reasons for injection (BTX A to B = 25.0%; botulin toxin A = 5.3%; p = 0.01). We did not find significant differences between groups based on the other variables. CONCLUSIONS Our findings suggest that higher number of sites rather than higher number of units or years of treatment are associated with the loss of effectiveness to BTX A. It is possible that the loss of effectiveness to the BTX is more strongly elicited when the injections are widely diffuse.

Abstract
PURPOSE OF REVIEW The most relevant advances in immune-mediated movement disorders are described, with emphasis on the clinical--immunological associations, novel antigens, and treatment. RECENT FINDINGS Many movement disorders previously considered idiopathic or degenerative are now recognized as immune-mediated. Some disorders are paraneoplastic, such as anti-CRMP5-associated chorea, anti-Ma2 hypokinesis and rigidity, anti-Yo cerebellar ataxia and tremor, and anti-Hu ataxia and pesudoathetosis. Other disorders such as Sydenham's chorea, or chorea related to systemic lupus erythematosus and antiphospholipid syndrome occur in association with multiple antibodies, are not paraneoplastic, and are triggered by molecular mimicry or unknown mechanisms. Recent studies have revealed a new category of disorders that can be paraneoplastic or not, and associate with antibodies against cell-surface or synaptic proteins. They include anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis, which may cause dyskinesias, chorea, ballismus or dystonia (NMDAR antibodies), the spectrum of Stiff-person syndrome/muscle rigidity (glutamic acid decarboxylase, amphiphysin, GABA(A)-receptor-associated protein, or glycine receptor antibodies), neuromyotonia (Caspr2 antibodies), and opsoclonus--myoclonus--ataxia (unknown antigens). SUMMARY Neurologists should be aware that many movement disorders are immune-mediated. Recognition of these disorders is important because it may lead to the diagnosis of an occult cancer, and a substantial number of patients, mainly those with antibodies to cell-surface or synaptic proteins, respond to immunotherapy.

Abstract
OBJECTIVES Multiple sclerosis is a degenerative disease of the CNS with a pathology consistent with immunological mediation. Although its cause is unknown, multiple factors are thought to influence both the onset and exacerbation of the disease, including both genetic background as well as environmental factors. METHODS We are interested in the effect of psychological stress on the onset and exacerbation of Theiler's virus-induced demyelinating disease (TVID), a murine model of MS in which viral persistence facilitates demyelination. In the current study, we determined whether chronic restraint stress (RS)-induced immunosuppression could result in the establishment of a persistent CNS infection in the normally TVID-resistant C57BL/6 mouse strain, resulting in demyelination. RESULTS Our data indicated that RS repeated over the course of 7 days was not sufficient to cause decreases in virus-specific adaptive immunity, and did not significantly alter CNS viral levels. Furthermore, chronic repeated RS lasting until 4 weeks after infection altered neither the development of virus-specific IgG nor motor function determined by Rotarod analysis. In addition, histological analysis of the CNS of stressed mice indicated no inflammation or demyelination on day 193 after infection. CONCLUSION These results suggest that stress alone is not sufficient to overcome genetic resistance to TVID in the C57BL/6 mouse strain.

Abstract
BACKGROUND Eosinophilia is frequently associated with peripheral neuropathy, and neuropathic pain is a major presentation. Little is known about the involvement of sensory nerve terminals and the vasculature in the skin of patients with eosinophilia. OBJECTIVES To investigate the skin innervation and the pathological abnormalities of the cutaneous vasculature and their clinical significance in eosinophilia-associated neuropathy. DESIGN Case series. SETTING National Taiwan University Hospital, Taipei, Taiwan. Patients Twelve patients with neuropathy and concomitant eosinophilia (with an eosinophilic ratio of white blood cell classification > 10% or absolute eosinophil count of > 1000/microL). INTERVENTIONS Clinical assessments of neurological deficits, laboratory tests, nerve conduction studies, and a skin biopsy specimen 3 mm in diameter taken from the distal leg without active skin lesions. MAIN OUTCOME MEASURES Quantitation of epidermal innervation, immunopathological findings of the cutaneous vasculature, and motor disability grade. RESULTS Six patients fulfilled the criteria of Churg-Strauss syndrome, and the other 6 patients were categorized as having primary eosinophilia. All of the 12 patients had mononeuropathy multiplex or polyneuropathy with sensory symptoms as the initial manifestation. Intraepidermal nerve fiber densities were reduced in 10 patients (83.3%), being significantly lower than in the controls (mean +/- SD, 2.12 +/- 2.30 vs 10.56 +/- 3.69 fibers/mm, respectively; P < .001) and negatively correlated with the disability grade (P = .003). Nine patients (75.0%), including all of the 6 patients with Churg-Strauss syndrome, had cutaneous vasculitis, and two-thirds of the 9 patients had perivascular infiltration of eosinophils. CONCLUSION Skin denervation with cutaneous vasculitis is a major manifestation of eosinophilia-associated neuropathy.

Abstract
Phospholipids are abundantly represented within the nervous system. Aim of our study was to evaluate the presence and fine specificity of anti phospholipid antibodies (aPLAb) among patients with monoclonal gammopathy associated neuropathy. Thirty nine percent of these patients had high titers of aPLAb, mostly associated with low levels of anti beta2 glycoprotein I, which suggests different antibody specificity compared to patients with anti phospholipid syndrome. Further 6/48 patients with dysimmune neuropathy without monoclonal gammopathy had positive aPLAb titers. APLAb strongly cross-reacted with sulfatide. These findings suggest an adjuntive role of aPLAb on nerve damage and may help to better understand the nerve binding properties of anti-sulfatide antibodies.

Abstract
Behavioral and movement disorders may have antibody responses where mimicry and signal transduction may lead to neuropsychiatric abnormalities. In our study, antibodies in pediatric autoimmune neuropsychiatric disorders associated with streptococci (PANDAS) reacted with the neuronal cell surface and caudate-putamen and induced calcium-calmodulin dependent protein (CaM) kinase II activity in neuronal cells. Depletion of serum IgG abrogated CaM kinase II cell signaling and reactivity of CSF was blocked by streptococcal antigen N-acetyl-beta-d-glucosamine (GlcNAc). Antibodies against GlcNAc in PANDAS sera were inhibited by lysoganglioside G(M1). Results suggest that antibodies from an infection may signal neuronal cells in some behavioral and movement disorders.

Abstract
Human immunodeficiency virus (HIV)-wasting syndrome might be facilitated by the HIVgp120 affecting the immunological system. We studied the effect (subchronic administration: 5 days) of HIVgp120, and a few immune-response mediators: regulated upon activation normal T-cell expressed and presumably secreted (RANTES), stromal derived factor-1alpha (SDF-1alpha), macrophage-derived chemokine (MDC), and their combination, on food and water intake in rats, motor control and pain perception. Eighty male adult Wistar rats received an intracerebroventricular (icv) administration of: vehicle 5 microl/day or 0.92 nmol daily of HIVgp120IIIB, RANTES, SDF-1alpha, or MDC, and the combination of RANTES+HIVgp120IIIB, SDF-1alpha+HIVgp120IIIB, or MDC+HIVgp120IIIB. Food and water intake was measured every day during administration, and 24 and 48 h after the last administration. Rats were also weighed the first and the last day of experiment in order to detect the impact of these treatments in the body weight. HIVgp120IIIB significantly decreased food and water intake. These rats gain less weight than the control (vehicle) and chemokines-treated subjects with exception of those treated with SDF-1alpha that also gain less weight. In addition, HIVgp120 deteriorated motor control. HIVgp120IIIB effects on food and water intake, and motor control were prevented by these chemokines. HIVgp120+RANTES, HIVgp120+SDF-1alpha, and SDF-1alpha alone induced hyperalgesia. Results suggest an interaction between HIVgp120 and the chemokine system to generate the HIV-wasting syndrome, the motor abnormalities and changes in pain perception.

Abstract
Poststreptococcal disorders exhibit a remarkable comorbidity of neurologic and psychiatric features. A similar combination of symptoms is also described in other conditions, such as connective tissue or paraneoplastic disorders, albeit less frequently. A better understanding of the underlying mechanisms associated with autoaggressive immune-mediated attack on the basal ganglia is required. This understanding will ideally aid clinicians in diagnosing these conditions and lead to appropriate clinical trials, for example, of chemoprophylaxis strategies to prevent recurrent streptococcal infection and of the use of immunosuppressive treatments.

Abstract
Anti-basal ganglia antibodies (ABGA) are associated with movement disorders in children, but have not been assessed in adult onset movement disorders. In a prospective assessment ABGA were positive in 65% of a group of 65 patients with atypical movement disorders, but were very rare in healthy adults and adults with idiopathic dystonia. An autoimmune mechanism may underlie a proportion of cases of atypical movement disorders.

Abstract
PURPOSE OF REVIEW Recently, autoaggressive immunological responses were included among the causative agents of basal ganglia dysfunction. Autoaggressive immune-mediated illnesses secondary to group A beta-haemolytic streptococcal infections present with motor and psychiatric symptoms, due to basal ganglia involvement. These disorders have been associated with serum antineuronal antibodies, relatively specific to human basal ganglia tissue. This review summarizes the most recent studies concerning antibasal ganglia antibodies, focusing on the associated phenotypes and the hypotheses concerning their pathogenicity. RECENT FINDINGS The spectrum of post-streptococcal neuropsychiatric disorders associated with antibasal ganglia antibodies seems broader than previously recognized. Other than chorea, tics and obsessive-compulsive disorder, which constituted the bulk of previously described disorders associated with antibasal ganglia antibodies, post-streptococcal neuropsychiatric disturbances include a wider range of motor and behavioural abnormalities, in keeping with the multifunctional role of the basal ganglia. An encephalitis lethargica-like illness following streptococcal infection was reported, and unusual adult-onset movement disorders associated with antibasal ganglia antibodies were documented. Moreover, investigators provided preliminary evidence for a pathogenic role of autoantibodies in Sydenham's chorea, the prototypic post-streptococcal neuropsychiatric disorder. SUMMARY Antibasal ganglia antibodies are relatively specific in identifying post-streptococcal neuropsychiatric disorders, which constitute a wider spectrum of movement disorders than previously recognized. Although their sensitivity in diagnosing Sydenham's chorea seems excellent, it is not yet possible to extrapolate this sensitivity to all the recently identified post-streptococcal neuropsychiatric disorders. The antigens targeted by these autoantibodies and their pathogenic importance are currently under investigation. Preliminary evidence suggests that antibasal ganglia antibodies may be pathogenic.

Abstract
BACKGROUND The spectrum of post-streptococcal brain disorders includes chorea, tics, and dystonia. The proposed mediators of disease are anti-basal ganglia (neuronal) antibodies (ABGA). AIM To evaluate ABGA as a potential diagnostic marker in a cohort of UK post-streptococcal movement disorders. METHODS Forty UK children presenting with movement disorders associated with streptococcal infection were recruited. ABGA was measured using ELISA and Western immunoblotting. To determine ABGA specificity and sensitivity, children with neurological diseases (n = 100), children with uncomplicated streptococcal infection (n = 40), and children with autoimmune disease (n = 50) were enrolled as controls. RESULTS The mean ELISA result was increased in the post-streptococcal movement disorder group compared to all controls and derived a sensitivity of 82.4% and specificity of 79%. The Western immunoblotting method to detect ABGA derived a sensitivity and specificity of 92.5% and 94.7% respectively. There was common binding to basal ganglia antigens of 40, 45, and 60 kDa. Immunofluorescence localised the antibody binding to basal ganglia neurones. CONCLUSION ABGA appears to be a potentially useful diagnostic marker in post-streptococcal neurological disorders. Western immunoblotting appears to be the preferred method due to good sensitivity and specificity and the ability to test several samples at once.

Abstract
PURPOSE OF REVIEW Autoimmune disease has long been intertwined with investigations of infectious causes. Antibodies that are formed against an infectious agent can, through the process of molecular mimicry, also recognize healthy cells. When this occurs, the immune system erroneously destroys the healthy cells causing autoimmune disease in addition to appropriately destroying the offending infectious agent and attenuating the infectious process. The first infectious agent shown to cause a post-infectious autoimmune disorder in the central nervous system was Streptococcus pyogenes in Sydenham's chorea. The present review summarizes the most recent published findings of central nervous system diseases that have evidence of a post-streptococcal autoimmune etiology. RECENT FINDINGS Sydenham's chorea and other central nervous system illnesses that are hypothesized to have a post-streptococcal autoimmune etiology appear to arise from targeted dysfunction of the basal ganglia. PANDAS (pediatric autoimmune disorders associated with streptococcal infections) is the acronym applied to a subgroup of children with obsessive-compulsive disorder or tic disorders occurring in association with streptococcal infections. In addition, there are recent reports of dystonia, chorea encephalopathy, and dystonic choreoathetosis occurring as sequelae of streptococcal infection. Investigators have begun to isolate and describe antistreptococcal-antineuronal antibodies as well as possible genetic markers in patients who are susceptible to these illnesses. SUMMARY Clinical and research findings in both immunology and neuropsychiatry have established the existence of post-streptococcal neuropsychiatric disorders and are beginning to shed light on possible pathobiologic processes.

Abstract
Sydenham's chorea (SC) occurs weeks or months after Group A streptococcal infection, and is characterized by involuntary, purposeless movements of the limbs, in addition to behavioural alteration. There is a body of evidence which suggests that SC is an immune-mediated brain disorder with regional localization to the basal ganglia. Recent reports have suggested that the spectrum of post-streptococcal CNS disease is broader than chorea alone, and includes other hyperkinetic movement disorders (tics, dystonia and myoclonus). In addition, there are high rates of behavioural sequelae, particularly emotional disorders such as obsessive-compulsive disorder, anxiety and depression. These findings have lead to the hypothesis that similar immune-mediated basal ganglia processes may be operating in common neuropsychiatric disease such as tic disorders, Tourette syndrome and obsessive-compulsive disorder. This review analyses the historical aspects of post-streptococcal CNS disease, and the recent immunological studies which have addressed the hypothesis that common neuropsychiatric disorders may be secondary to basal ganglia autoimmunity.

Abstract
The presence of anti-Toxoplasma gondii IgM and IgG antibodies was studied in samples of blood serum taken from eighty dogs with nervous symptoms at the Serviço de Enfermidades Infecciosas dos Animais, Faculdade de Medicina Veterinária e Zootecnia, Unesp, Botucatu, São Paulo, Brazil. The frequency of IgG titers were 16 (13.7%), 64 (13.7%), and 256 (5%), and for IgM titers were 16 (7.5%), 64 (15%), and 256 (8.7%). Positive reactions were more frequent in the older animals, males, from a rural environment, in constant contact with small animals, principally birds and rodents. There was a higher frequency of a positive reaction in dogs fed with kitchen food, especially in those fed with raw ingredients. The most common neurological pictures were alterations in consciousness, in movement, and in the hand-cart test. The percentage of reagents with specific IgM antibodies was high, indicating active infections, but the possibility of co-infection with the distemper virus can not be discarded, and this may be a predisposing factor for toxoplasmosis infection, once the distemper virus has a potent immunosuppressive action.

Abstract
Elevated titers of serum antibodies against GM(1)-ganglioside are associated with a variety of autoimmune neuropathies. Although much evidence indicates that these autoantibodies play a primary role in the disease processes, the mechanism of their appearance is unclear. Low-affinity anti-GM(1) antibodies of the IgM isotype are part of the normal human immunological repertoire. In patients with motor syndromes, we found that in addition to the usual anti-GM(1) antibodies, the sera contain IgM-antibodies that recognize GM(1) with higher affinity and/or different specificity. This latter type of antibodies was not detected in other autoimmune diseases. We studied the fine specificity of both normal and motor disease-associated antibodies using HPTLC-immunostaining of GM(1) and structurally related glycolipids, soluble antigen binding inhibition, and GM(1) affinity columns. Normal low-affinity anti-GM(1) antibodies cross-react with GA(1) and/or GD(1b). In the motor syndrome patients, different populations of antibodies characterized by their affinity and cross-reactivity were detected. Although one population is relatively common (low affinity, not cross-reacting with GA(1) and GD(1b)), there are remarkably few sera having the same set of populations. These results suggest that the appearance of the new antibody populations is a random process. When the different antibody populations were analyzed in relation to the three-dimensional structure of GM(1), a restricted area of the GM(1) oligosaccharide (the terminal Galbeta1-3GalNAc) was found to be involved in binding of normal anti-GM(1) antibodies. Patient antibodies recognize slightly different areas, including additional regions of the GM(1) molecule such as the NeuNAc residue. We hypothesize that disease-associated antibodies may originate by spontaneous mutation of normal occurring antibodies.

Abstract
The T-cell immune deficiency was found to be more obvious in offspring of rats with a right-side brain injury. The EMG pattern changed in accordance with the brain injury lateralisation in the muscles responsible for posture asymmetry. The offspring EMG disorders were more obvious in cases of a right-side brain injury in mothers. The right-side brain injury in mothers led to a higher negative emotionality and a diminished tentative-research behaviour in "open-field" tests in 30-day old offspring.

Abstract
A number of disorders, including childhood-onset obsessive compulsive disorder (OCD) and Gilles de la Tourette's syndrome (TS), are known to be neurobiological in nature. Both TS and OCD are neuropsychiatric diagnoses that involve congitive and perceptual dysfunction in addition to motor and psychiatric manifestations. The association of the B-cell marker with both Sydenham's chorea and a group of neuropsychiatric disorders, such as OCD, tics, and TS, has been useful as a marker in these diseases. This evidence, coupled with the recent finding of anti-brain antibodies in the sera of these patients, raises a number of interesting questions concerning the pathological mechanisms involved in these diseases. Thus, further molecular characterization of the brain and streptococcal antigens will be crucial to our understanding of the neurophysiological processes involved in these disorders.

Abstract
In recent years there has been renewed interest in the role of autoimmunity in many neurological disorders such as multiple sclerosis and neurodegenerative diseases. Research advances in this field have led to the discovery of new potential therapeutic strategies. There are, however, only a few neurological disorders in which an autoimmune origin has been adequately documented and definitely confirmed. The most important neurological diseases causing movement disorders in which an autoimmune basis has been demonstrated are summarized in this review. The possible role of immunity with the most frequent movement disorders such as parkinsonism or dystonia is also commented.

Abstract
Mice injected with Rhodococcus aurantiacus by the intravenous (i.v.) route show neurological disorders, hemiparesis, vertical headshake and turn-round gait after day 7 postinfection (p.i.). Neurological symptoms caused by i.v. inoculation of R. aurantiacus were relieved by treatment with levodopa (l-dopa). R. aurantiacus was isolated from the brain and was found to be completely eliminated at day 7 p. i. Focal encephalitis was mainly observed in the brain stem, and T cells could be isolated from the brain after day 7 p.i. Administration of both an anti-CD4 monoclonal antibody (mAb) and an anti-CD8 mAb suppressed neurological symptoms. These results suggest that R. aurantiacus induces movement disorders in mice, and that the symptoms are mediated by T cells infiltrating the brain, rather than directly by the bacterium.

Abstract
HIV-1 infection of brain may be associated with multiple treatment targets, only the most severe of which is represented by HAD. Focusing on earlier treatment targets such as MCMD and cognitive-motor impairment in the absence of any clinical disorder (as well as neuroprotection) may prove to be of greater clinical utility in the treatment and prevention of such impairment than a focus on later-stage cognitive-motor disease, when neuronal cell death is already extensive. This may be especially important now that improvements using the protease inhibitors in triple-drug combination regimens have reduced plasma viral load to unmeasurable levels, while these drugs do not penetrate the CSF well. Currently, peripheral blood markers do not appear to be highly sensitive for central nervous system impairment, and specific CSF laboratory markers have some limited value at present-while requiring a lumbar puncture to obtain. Hence, a role for noninvasive techniques using neuroimaging exists in the clinical management of HIV-1-infected patients. To date, structural imaging techniques have proven limited in value for HIV-1-specific impairment. Several functional techniques (PET, SPECT, and MR spectroscopy) have now provided promising results for the purposes of identifying clinically significant dysfunction, relating such dysfunction to clinical neuropsychiatric symptom status, and for treatment response monitoring. Further studies are needed to examine the extent to which such imaging modalities not only parallel clinically relevant aspects of HIV-1 disease progression, but also match specific types of neuropsychologic performance deficits with potential significance for neuroanatomical localization. It is particularly important to include neurophysiological, neuroimmunological, and virological measures in studies that examine clinical neuropsychiatric status with neuroimaging techniques. In addition, the inclusion of neuropathology data, where possible, is important because demonstration of HIV-1 encephalitis cannot be equated with clinical disorder and because specific HIV-1-associated pathological changes have not yet been proven to be assessed well with neuroimaging techniques (e.g., the extent of microglial cell and macrophage activation). Also, treatment response studies are needed in conjunction with primary antiretroviral therapy regimens specifically aimed at central nervous system penetration (e.g., GW1592, GW141, and nevirapine). The results of such work will provide the data required to determine whether these promising functional neuroimaging techniques will aid in meeting the expected, imminent increase in clinical burden of this frequent complication of HIV-1 infection.

Abstract
We compared the binding of human antibodies from patients with neuropathy to the myelin-associated glycoprotein (MAG), to its cross-reactive glycolipid sulfoglucuronyl paragloboside (SGPG), and to sections of peripheral nerve. Titers were correlated with the clinical presentation and results of electrophysiological and pathological studies. Most patients had a predominantly sensory or sensorimotor demyelinating neuropathy and highly elevated antibodies to both MAG and SGPG, but 2 had highly elevated antibodies to MAG alone, and 1 to SGPG alone. Two patients had predominantly motor neuropathy and highly elevated antibodies to SGPG which reacted with MAG by Western blot but not by enzyme-linked immunosorbent assay. One patient had amyotrophic lateral sclerosis and antibodies to SGPG but not to MAG. These studies indicate that the neuropathic syndrome associated with anti-MAG or -SGPG antibodies are more heterogeneous than previously suspected, and that although most of the antibodies react with both MAG and SGPG, some may react with MAG or SGPG alone.

Abstract
Botulinum toxin is a valuable technology for the treatment of regional movement disease. High-dose applications ( > 100 LD50 units per injection cycle) have been associated with sensitization that renders further therapeutic injections ineffective. The true incidence of sensitization is probably underestimated by the mouse bioassay. Other immunotypes of botulinum toxin have been effective in producing some therapeutic benefit; however, duration of action (botulinum toxin type F) and lower potencies may make these less attractive alternatives than botulinum type A. Increased specific activity botulinum toxin may be a method to reduce antigen exposure and mitigate against immunoresistance associated with dystonia therapy. Limiting the dose to < or = 100 LD50 units per injection cycle may limit this complication in the interim.

Abstract
The neuropsychiatric manifestations of systemic lupus erythematosus (SLE) are diverse but, among them, movement disorders are distinctly uncommon. We describe a 30-year-old female with SLE who developed sudden onset of right-sided hemiballismus. Previous cerebral venous thrombosis and a poor obstetric history suggested the antiphospholipid syndrome but only minimally elevated levels of anticardiolipin antibodies were detected. The underlying pathology could not be established but was most likely to have been a microinfarct of the contralateral subthalamic nucleus. Our patient responded rapidly to haloperidol alone without the requirement for corticosteroids.

Abstract
We studied clinical and electrodiagnostic features of 9 patients with very high titers (> 1:10,000) of serum IgM binding to a CNS myelin antigen (CMA) preparation that copurified with myelin-associated glycoprotein (MAG). We found that 8 of the 9 patients had a combined syndrome of gait ataxia and polyneuropathy (GAPN) with late-age onset (mean = 70 years of age). In the 8 GAPN patients progressive difficulty with ambulation led to significant functional disability and frequent falling. Examination showed a wide-based unsteady gait, especially when standing still or turning. There was mild-to-moderate distal sensory loss with involvement of joint position sense only in the toes. Motor changes, when present, were mild and mainly involved distal leg musculature. Treatment of 5 GAPN patients resulted in clear improvement of 2 after intravenous human immunoglobulin and of 3 others after other immunodulating agents. Immune-mediated GAPN syndromes with high titers of serum IgM binding to CMA appear to be treatable causes of gait disorders in older patients.

Abstract
No definitive evidence for the participation of the immune system in progressive brain damage has been previously reported. However, glial cells continue to accumulate after degeneration of neurons appears to be completed, and a recent study showed that microglia and leukocytes also accumulate after brain damage. Thus, it seemed possible that immune responses might play a role in the delayed effects. Cyclosporin A (CsA) is a cyclic undecapeptide of fungal origin with a strong immunosuppressive action but low myelotoxicity. We examined the effect of CsA administration on three different kinds of animal models for neurological deficits. Late onset reduction of muscarinic receptors after transient forebrain ischemia in gerbils was prevented by daily post-ischemic administration of CsA. This indicates that an immune mechanism may be involved in the progressive brain damage occurring after transient ischemia. On the other hand, CsA exacerbated iminodipropionitrile-induced dyskinesia both behaviorally and biochemically. CsA also mimicked pentylenetetrazol-induced seizures. These findings suggest that immune mechanisms may play important roles in the progression of brain damage and possibly that immunosuppressants might open a new chapter in the pathophysiology and treatment of chronic progressive neurodegenerative diseases. Further investigations on the immune response in the progressive brain damage are needed.

Abstract
A group of 13 children, aged 2 to 14 years, and diagnosed with Guillain-Barré syndrome has been analyzed. Clinical features and outcome were retrospectively studied. In 75% of the patients there was an infectious illness previous to the neurologic symptoms and in four children the etiologic agent was demonstrated. Motor deficits affecting the limbs and muscle stretch reflexes were absent in all thirteen patients. Cranial nerve involvement showed-up in 46%. Meningitic symptoms occurred in 62% of the cases. One of the children developed the Fisher syndrome variant. Two patients required assisted ventilation. Three children showed associated immunologic abnormalities, with one of the patients having a selective IgA deficiency, another child showing an increment in IgE and the other Kawasaki syndrome. We have not demonstrated differences in the outcome between the patients with corticoid treatment.

Abstract
OBJECTIVE To determine whether children with recent onset of movement disorders (Tourette syndrome, motor and/or vocal tics, chorea, choreiform movements) show evidence of serological antibodies directed against the human central nervous system as previously documented in research on Sydenham's chorea. METHODS Serum antibodies against previously frozen human caudate nucleus sections were analyzed using a blinded design and immunofluorescent staining methods. The sera of one group of 50 children referred for evaluation of attention deficit hyperactivity disorder, behavior disorders, and learning disabilities (24 with an associated movement disorder) seen between June 1989 and June 1990 were analyzed. The study was replicated in 33 children (21 with an associated movement disorder) seen between June 1990 and November 1990. RESULTS In the original sample of 50 children, those with movement disorders were significantly more likely to have evidence of antineuronal antibodies than were those without movement disorders (odds ratio [OR] 4.80, 95% confidence interval [CI] 2.58 to 8.93). Results of the replication were similar (OR 6.00, 95% CI 2.56 to 14.03). For the total group, the OR was 5.50, (95% CI 3.54 to 8.99), which is highly significant. The percentage of children with a movement disorder whose sera were strongly positive for antineuronal antibodies (44%) was very similar to that previously found in children with Sydenham's chorea (46%). Children with movement disorders were also more likely than children without movement disorders to have at least one antistreptococcal titer elevated. CONCLUSIONS The data strongly suggest an association between antecedent group A beta-hemolytic streptococcal infection as inferred from elevated antistreptococcal titers and the presence of serum antineuronal antibodies, which may, in turn, be linked to childhood movement disorders.

Abstract
We report three children with hemidystonia in whom anti-cardiolipin (aCL) antibodies were demonstrated. Systemic lupus erythematosus was excluded on the basis of both clinical and serological criteria, and the diagnosis of primary antiphospholipid syndrome (PAPS) was made. In two cases, aCL antibodies could be causally related to a presumed immune-mediated thrombotic event involving the basal ganglia as shown by magnetic resonance imaging (MRI). In the remaining patient the finding of white matter alteration on NMR might be due to cross-reactivity of anti-phospholipid (aPL) antibodies with cerebral phospholipids, resulting in demyelination. We suggest that PAPS must always be considered when isolated or recurrent focal cerebral ischaemia, and particularly hemidystonia, occur in childhood.

Abstract
Serum antiganglioside antibodies were investigated in motor neuron disease (MND) and in chronic or acute immune-mediated motor-dominant neuropathies. IgM antibody binding to GM1 and GA1, reacting with Gal beta 1-3GalNAc epitope, was seen in 5 out of 26 cases of MND. IgM antibody binding to Gal beta 1-3GalNAc epitope was also detected in 3 out of 3 cases with motor dominant neuropathy with multifocal conduction block (MNMCB). The IgM M-protein in a case with motor dominant neuropathy bound to GM1, GD1b, GM2 but not to GA1. This M-protein may recognize carbohydrate epitope including sialic acid. Antiganglioside antibodies were detected in 11 out of 16 cases with Guillain-Barré syndrome (GBS). Among them, anti-GM1 antibodies were detected in 6 cases. Gal beta 1-3GalNAc epitope was recognized in 3 cases, and GM1 was monospecifically recognized in 3 cases. Thus the binding specificities of anti-GM1 antibody in motor dominant neuropathies were varied. The titers of anti-GM1 antibodies in 1 case with MNMCB and in 6 cases with GBS were more than 1:160, whereas those in MND were less than 1:80. The high titers of antibody in MNMCB and GBS decreased in association with clinical improvement, suggesting that they are closely related with the disease process. Although the titers are low, anti-GM1 antibody in MND may give us a clue to elucidate the pathogenetic mechanisms of this intractable disease.
