Abstract
Background About 10% of cluster headache patients have the chronic form. At least 10% of this chronic group is intractable to or cannot tolerate medical treatment. Open pilot studies suggest that occipital nerve stimulation (ONS) might offer effective prevention in these patients. Controlled neuromodulation studies in treatments inducing paraesthesias have a general problem in blinding. We have introduced a new design in pain neuromodulation by which we think we can overcome this problem. Methods/design We propose a prospective, randomised, double-blind, parallel-group international clinical study in medically intractable, chronic cluster headache patients of high- versus low-amplitude ONS. Primary outcome measure is the mean number of attacks over the last four weeks. After a study period of six months there is an open extension phase of six months. Alongside the randomised trial an economic evaluation study is performed. Discussion The ICON study will show if ONS is an effective preventive therapy for patients suffering medically intractable chronic cluster headache and if there is a difference between high- and low-amplitude stimulation. The innovative design of the study will, for the first time, assess efficacy of ONS in a blinded way.

Abstract
Background Cluster headache (CH) is a primary headache disorder that is diagnosed based on the patient's history. For large-scale epidemiologic and genetic studies, a web-based, preferably short, questionnaire can be a feasible alternative to replace time-consuming clinical interviews. Methods Self-reported CH patients were enrolled via our research website. Participants meeting screening criteria were directed to the Leiden University Cluster headache Analysis program (LUCA) questionnaire. Individual diagnoses were calculated using an algorithm based on International Headache Society criteria. Subsequently, semi-structured telephone interviews were carried out to validate the LUCA questionnaire. The shorter Quick Ascertainment of Cluster Headache (QATCH) questionnaire for diagnosing CH was constructed by using logistic regression to select the most predictive questions. Results Via our website 437 self-reported CH patients were recruited. Of these, 291 patients were included in this cross-sectional study. The LUCA questionnaire was valid and accurate. Using logistic regression, three questions (QATCH) provided similar sensitivity (53.8% vs. 57.2%), specificity (88.9% vs. 87.5%), positive predictive value (95.5% vs. 95.9%) and negative predictive value (30.8% vs. 28.8%) compared with the LUCA questionnaire. Conclusion The web-based LUCA questionnaire was accurate and reliable in diagnosing CH among self-reported patients. Males with headache attacks of short duration and long headache-free intervals (months to years) are very likely to have CH.

Abstract
Parkinson's disease is a complex disorder with many fascinating features. Its onset is creeping, the progression is slow but inevitable. There are motor symptoms, such as a tremor, rigidity, bradykinesia, mask-like facial expression, and postural abnormalities, but also hallucinations, cognitive deterioration, and depression. In many novels, fictive patients with Parkinson's disease play a role. It seems that authors have used many aspects of the disease to emphasize their messages. Their narratives include themes such as rigidity, petrifaction, confusion, dementia, and hallucinations. In this chapter, as examples, several protagonists with Parkinson's disease will be described from works of John Updike, Jonathan Franzen, Sue Miller, J.M. Coetzee, and John Harding, among others.

Abstract
OPINION STATEMENT Hemiplegic migraine (HM) is a rare subtype of migraine with aura, characterized by transient hemiparesis during attacks. Diagnosis is based on the International Classification of Headache Disorders criteria (ICHD-II). Two types of HM are recognized: familial (FHM) and sporadic hemiplegic migraine (SHM). HM is genetically heterogeneous. Three genes have been identified (CACNA1A, ATP1A2, and SCN1A) but more, so far unknown genes, are involved. Clinically, attacks of the 3 subtypes cannot be distinguished. The diagnosis can be confirmed but not ruled out by genetic testing, because in some HM patients other, not yet identified, genes are involved. The presence of additional symptoms (such as chronic ataxia or epilepsy) may increase the likelihood of identifying a mutation. Additional diagnostics like imaging, CSF analysis, or an EEG are mainly performed to exclude other causes of focal neurological symptoms associated with headache. Conventional cerebral angiography is contraindicated in HM because this may provoke an attack. Because HM is a rare condition, no clinical treatment trials are available in this specific subgroup of migraine patients. Thus, the treatment of HM is based on empirical data, personal experience of the treating neurologist, and involves a trial-and-error strategy. Acetaminophen and NSAIDs often are the first choice in acute treatment. Although controversial in HM, triptans can be prescribed when headaches are not relieved sufficiently with common analgesics. An effective treatment for the severe and often prolonged aura symptoms is more warranted, but currently no such acute treatment is available. Prophylactic treatment can be considered when attack frequency exceeds 2 attacks per month, or when severe attacks pose a great burden that requires reduction of severity and frequency. In no strictly preferred order, flunarizine, sodium valproate, lamotrigine, verapamil, and acetazolamide can be tried. While less evidence is available for prophylactic treatment with topiramate, candesartan, and pizotifen, these drugs can also be considered. The use of propranolol in HM is more controversial, but evidence of adverse effects is insufficient to contraindicate beta-blockers.

Abstract
Protagonists who are locked-in can be found throughout fiction, probably because being locked-in serves as a strong philosophical metaphor for human existence. In this chapter, three protagonists who are locked-in due to physical/medical reasons will be described. The fictitious stories of Noirtier from The Count of Monte Cristo by Alexandre Dumas and that of Madame Raquin from Thérèse Raquin by Émile Zola are followed by the real-life story of Jean-Dominique Bauby's The Diving Bell and the Butterfly. Dumas' Noirtier is considered the first description of the locked-in syndrome in literature, and Madame Raquin appears to be locked-in also, but her description leaves many questions. Bauby's autopathography is chosen from many several similar discourses as it contains cross-references to Noirtier, Dumas' prototype of the syndrome, but also because it is of high literary value. The similarities and remarkable differences between these three case reports of this existentialistically important state of being will be highlighted, with an emphasis on the focus of their narratives.

Abstract
OBJECTIVE To describe the prevalence of aura in a Dutch cluster headache (CH) population. DESIGN Cross-sectional, epidemiological study. METHOD As part of a large-scale study into headaches conducted in Leiden (the Netherlands), patients experiencing headaches were identified by means of questionnaires on a headache website. One group of patients with CH was approached by telephone and an interview on aura-related symptoms was performed by means of a standardized questionnaire. The presence of migraine co-morbidity was also investigated. RESULTS Of the interviewed CH patients, 22 out of 244 (9.0%) had aura-related symptoms preceding a CH attack, which were predominantly visual in nature. The majority (72.7%) of these patients did not have migraine co-morbidity. CONCLUSION Aura-related symptoms can occur in CH without migraine co-morbidity. In clinical practice, it should be taken into account that the presence of an aura does not always indicate migraine.

Abstract
OBJECTIVE Diffuse iron deposition in the brain is commonly found in older people. One of the possible mechanisms that contribute to this iron deposition is cerebral small vessel disease. The aim of this study is to quantify diffuse iron deposition in patients with the hereditary small vessel disease cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). METHODS 25 NOTCH3 mutation carriers and 18 healthy controls were examined using high-resolution T2*-weighted imaging on a 7 T whole body MRI scanner. Susceptibility-weighted MRI scans were analysed for areas of signal loss and increased phase shift. Phase shift measurements in deep grey nuclei, cortex and subcortical white matter were compared between mutation carriers and controls. For confirmation, ex vivo brain specimens from another three patients with CADASIL were analysed for iron deposition using ex vivo MRI combined with iron histochemistry. RESULTS In vivo MRI showed areas of decreased signal intensity and increased phase shift in mutation carriers. Compared with healthy controls, mutation carriers had significantly higher phase shift in the putamen (p=0.0002) and caudate nucleus (p=0.006). Ex vivo MRI showed decreased signal intensity in the putamen and caudate nucleus in all specimens. Histochemistry confirmed the presence of iron deposition in these nuclei. CONCLUSIONS This study demonstrates increased diffuse iron accumulation in the putamen and caudate nucleus in patients with the small vessel disease CADASIL. This supports the hypothesis that small vessel disease contributes to the process of increased iron accumulation in the general population.

Abstract
Before he became the initiator of the surrealist movement, André Breton (1896-1966) studied medicine and worked as a student in several hospitals and as a stretcher bearer at the front during World War I. There he became interested in psychiatric diseases such as hysteria and psychosis, which later served as a source of inspiration for his surrealist writings and thoughts, in particular on automatic writing. Breton worked under Joseph Babinski at La Pitié, nearby La Salpêtrière, and became impressed by the 'sacred fever' of the famous neurologist. In this article, we describe the relationship between Breton and Babinski and try to trace back whether not only Breton's psychiatric, but also his neurological experiences, have influenced surrealism. We hypothesize that Breton left medicine in 1920 partly as a consequence of his stay with Babinski.

Abstract
Since multiple sclerosis (MS) has its onset at a young age, it is valuable to know how it affects life plans and future perspectives of patients. Through two narratives, this aspect is discussed in this article. The first is the autobiographical journal: The Journal of a Disappointed Man by WNP Barbellion, published in 1920, and the other one is from a contemporary patient. Despite the fact that both narratives are derived from different centuries, clear similarities have been perceived in the patients life plans and future perspectives. The narratives show that the life plans of both patients were adjusted due to physical limitations. Additionally, both patients experienced sorrows for losing the ability to perform passionate hobbies during their life. Moreover, a strong sense of uncertainty was expressed in both narratives concerning their future.

Abstract
BACKGROUND In the literary novel Kurgast (1925), translated in English as A guest at the spa, the Nobel laureate Hermann Hesse describes the treatment of his own sciatica. METHODS We compare Hesse's description of 85 years ago with a transcript of an interview with a contemporary patient with sciatica. The narratives of both texts were analyzed. RESULTS Both narratives start with hope on full recovery. Later this changes into the realization that one needs to accept that some symptoms are irreversible and will be permanent. CONCLUSIONS Although there currently is better understanding, diagnostic imaging and treatment of sciatica, a strong similarity in narrative type between the two stories was observed. Literary narratives can reflect every day practice, and probably can also be used to give better insight in dealing with diseases.

Abstract
Introduction: Familial hemiplegic migraine (FHM) is characterized by the familial occurrence of migraine attacks with fully reversible transient hemiplegia. Mutations in three different genes have been identified; CACNA1A (FHM1), ATP1A2 (FHM2) and SCN1A (FHM3). Besides hemiplegia, several other symptoms have been described in FHM 1–3 mutation carriers, including epilepsy and cerebellar symptoms. Case report: We describe two patients in whom hemiplegic attacks were not the presenting symptom, but in whom an otherwise unexplained head tremor led us to search for FHM mutations. Both patients carried a mutation in the CACNA1A gene. Discussion: CACNA1A mutations can give significant symptoms other than (hemiplegic) migraine as reason for presentation.

Abstract
It is widely believed that Pablo Picasso suffered from migraine. The main cause for this is our suggestion made 10 years ago that some of Picasso's paintings resemble migraine auras. Here we critically look back at our own hypothesis. We conclude that, although the idea is still fascinating, there is no proof of Picasso suffering from migraine with aura.

Abstract
Background and Purpose—
Cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditary small vessel disease. Although postmortem studies have demonstrated mural thickening in leptomeningeal arteries and lenticulostriate perforating arteries, it is unclear whether this also leads to luminal narrowing. High-field MRI scanners enable in vivo imaging of the lumen of the lenticulostriate arteries. The aim of this study is to examine the luminal diameters of lenticulostriate arteries in living patients with CADASIL and to investigate whether luminal narrowing is correlated with the number of lacunar infarcts in the basal ganglia.
Methods—
Twenty-two NOTCH3 mutation carriers and 11 healthy control subjects were examined using high-resolution 3-dimensional time-of-flight MR angiography imaging on a 7-T MRI scanner. Scans were analyzed for the presence of focal stenotic segments. The total number, length, and total cross-sectional area of lenticulostriate arteries were measured and compared between mutation carriers and control subjects. These measurements were correlated with age, disease duration, and number of lacunar infarcts in the basal ganglia.
Results—
No stenotic segments were observed. No differences between mutation carriers and control subjects were found in total number of end branches (mutation carriers: mean, 14.6; control subjects: mean, 12.8), length of the lenticulostriate system, or total cross-sectional area of lenticulostriate artery lumina. Measurements of lenticulostriate artery lumina were not associated with lacunar infarct load in the basal ganglia area or with basal ganglia hyperintensities.
Conclusions—
Three-dimensional time-of-flight MR angiographic on 7 T showed no differences in luminal diameters of lenticulostriate arteries between patients with CADASIL and control subjects.

Abstract
Objective: Our objective was to study the long-term prognosis of sporadic hemiplegic migraine (SHM). Methods: We performed a longitudinal follow-up study in 18 patients who were diagnosed with SHM between 1993 and 1996. Follow-up time between the first and second survey ranged from nine to 14 years. These patients were included as part of a genetic study in which we systematically analysed the role of the three known familial hemiplegic migraine (FHM) genes. Results: In 12 out of 18 patients the clinical diagnosis was unchanged. In two of the six remaining patients the attacks were no longer associated with hemiplegia; one of them had an ATP1A2 gene mutation (E120A). In the four other patients, the diagnosis changed into FHM, because a family member had developed hemiplegic migraine since the initial diagnosis was made. In two of the four patients a mutation was demonstrated ( CACNA1A [R583Q] and ATP1A2 [R834X]). Conclusion: This study shows that the diagnosis of SHM changes into FHM in a considerable percentage of patients (22% [4 of 18]), almost a decade after the initial diagnosis. This indicates that a careful follow-up of SHM patients and their families is advisable for optimal care and counseling. Diagnostic screening of FHM genes in SHM patients can be of value. Our genetic and clinical follow-up studies reinforce the evidence that FHM and SHM are part of the same spectrum of migraine.

Abstract
Genetic factors are likely to play a role in cluster headache but are not simply accounted for. A small number of family studies have illustrated the role of genetics, and a few inconclusive studies assessed candidate genes for cluster headache. These clinical genetic studies are reviewed and the author's results from a large database of cluster headache patients are reported. The importance of genetic factors in cluster headache pathophysiology and comment on difficulties in genetic research of cluster headache are discussed.

Abstract
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is caused by mutations in the NOTCH3 gene and is clinically characterized by recurrent stroke, cognitive decline, psychiatric disturbances and migraine. The prevalence of migraine in CADASIL is slightly higher than in the general population, and the proportion of migraine with aura is much higher. The pathophysiological mechanism that leads to increased aura prevalence in CADASIL is unknown. Possible mechanisms of the excess of migraine with aura are an increased susceptibility to cortical spreading depression (CSD) or a different expression of CSD. It is also possible that the brainstem migraine area is involved in CADASIL. Last, it is possible that the NOTCH3 mutation acts as a migraine aura susceptibility gene by itself. In this narrative review we summarize the literature about migraine in CADASIL, with a special focus on what CADASIL might teach us about the pathophysiology of migraine.

Abstract
Migraine patients who experience an average of 2 or more attacks per month are eligible for preventive treatment as well as treatment for acute attacks. The decision to offer preventative treatment is also made on the basis of the average attack duration, severity of the attacks, and response to attack treatment. Prior to initiating preventive treatment, the average attack frequency per month should be assessed, preferably by means of a headache diary over a number of months, as attack frequency is extremely variable. None of the currently available preventive drugs, such as beta-blockers, sodium valproate, topiramate and candesartan, were developed specifically for treating migraine, but were all originally intended for other indications. 50% of the migraine patients receiving preventive treatment can expect a 50% reduction in attacks, and the remaining attacks often seem to be less severe. The effects of the drugs are often unpredictable per individual, and side-effects frequently lead to early discontinuation of treatment. Drugs usually prescribed for cardiovascular disorders are often used. In the case of a disorder such as migraine with a high burden of disability, patients with cardiovascular or pulmonary comorbidity should receive medication that is optimally adjusted for both indications.

Abstract
The term 'retinal migraine' is probably often wrongly applied. The primary reason for this is a confusion of nomenclature. No consensus exists in the neurological and ophthalmological literature on the diagnosis of 'retinal migraine'. A diagnosis of 'retinal migraine' should be avoided if no typical migraine headache is experienced following the visual symptoms. It is also a matter of debate whether retinal migraine can lead to permanent visual loss. If a patient complains of monocular visual loss, he or she may in fact have hemianopia.

Abstract
Insight into the molecular mechanisms involved in primary headaches is important to identify drug targets for improving treatment of patients, but essentially lacking. Genetic research is increasingly successful in pinpointing these mechanisms. Most progress has been made for Familial Hemiplegic Migraine, a rare subtype of migraine with aura. Three genes (CACNA1A, ATP1A2 and SCN1A) have been identified that all encode ion transporters. Cellular and transgenic mouse studies suggest that neuronal hyperexcitability and increased susceptibility to cortical spreading depression, the correlate of migraine aura, are important molecular mechanisms in migraine. Investigating monogenic diseases in which migraine is a prominent feature such as CADASIL, which is caused by mutations in the NOTCH3 gene, can help understanding the pathology of migraine. Candidate gene association studies and linkage studies in the common forms of migraine were less successful. Except for the MTHFR gene no gene variant has been identified yet. Convincingly demonstrated genetic findings in other primary headaches such as cluster headache and tension-type headache are even rarer. However, with current technical possibilities of massive genotyping and international efforts to collect large well-phenotyped patient cohorts, the first gene variants for various primary headache types are likely to be discovered in the coming decade.

Abstract
OBJECTIVE To study the clinical spectrum of CACNA1A S218L mutation carriers with special attention to "early seizures and cerebral oedema after trivial head trauma (ESCEATHT)", a combination of symptoms which resembles the "juvenile head trauma syndrome". PATIENTS AND METHODS In two patients with ESCEATHT all exons of CACNA1A were sequenced. Both patients also had hemiplegic migraine and ataxia. Subsequently, we screened the literature for S218L mutation carriers. RESULTS In both patients, a de novo S218L mutation in the CACNA1A gene was found. In addition, we identified 11 CACNA1A S218L carriers from the literature. Of these 13 S218L mutation carriers, 12 (92%) had ataxia or cerebellar symptoms and nine (69%) had hemiplegic migraine that could be triggered by trivial head trauma. Three mutation carriers had the complete ESCEATHT phenotype. Seven (54%) had seizures (four had early post-traumatic seizures) and five (38%) had oedema as detected by MRI/CT. CONCLUSIONS The CACNA1A S218L mutation is associated with familial hemiplegic migraine, ataxia and/or ESCEATHT. A minority of S218L mutation carriers have the complete ESCEATHT phenotype but a high percentage of patients had one or more ESCEATHT symptoms. As the S218L mutation enhances the propensity for cortical spreading depression (CSD), we postulate a role for CSD not only in hemiplegic migraine but also in early seizures and cerebral oedema after trivial head trauma. As this combination of symptoms is part of the unexplained "juvenile head trauma syndrome", a similar molecular mechanism may underlie this disorder.

Abstract
It is remarkable that migraine is a prominent part of the phenotype of several genetic vasculopathies, including cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL), retinal vasculopathy with cerebral leukodystrophy (RVCL) and hereditary infantile hemiparessis, retinal arteriolar tortuosity and leukoencephalopahty (HIHRATL). The mechanisms by which these genetic vasculopathies give rise to migraine are still unclear. Common genetic susceptibility, increased susceptibility to cortical spreading depression (CSD) and vascular endothelial dysfunction are among the possible explanations. The relation between migraine and acquired vasculopathies such as ischaemic stroke and coronary heart disease has long been established, further supporting a role of the (cerebral) blood vessels in migraine. This review focuses on genetic and acquired vasculopathies associated with migraine. We speculate how genetic and acquired vascular mechanisms might be involved in migraine.

Abstract
BACKGROUND AND PURPOSE Validation of the Boston criteria for the in vivo diagnosis of cerebral amyloid angiopathy (CAA) is challenging, because noninvasive diagnostic tests do not exist. Hereditary cerebral hemorrhage with amyloidosis-Dutch type is an accepted monogenetic model of CAA and diagnosis can be made with certainty based on DNA analysis. The aim of this study was to analyze and refine the existing Boston criteria in patients with hereditary cerebral hemorrhage with amyloidosis-Dutch type. METHODS We performed T2*-weighted MRI in 27 patients with hereditary cerebral hemorrhage with amyloidosis-Dutch type to assess the presence and location of microbleeds, intracranial hemorrhages, and superficial siderosis. Using the Boston criteria, subjects were categorized as having: no hemorrhages, possible CAA, probable CAA, and hemorrhagic lesions not qualifying for CAA. The sensitivity of the Boston criteria was calculated separately using intracranial hemorrhages only and using intracranial hemorrhages and microbleeds. RESULTS The sensitivity of the Boston criteria for probable CAA increased from 48% to 63% when microbleeds were included. For symptomatic subjects only, the sensitivity was 100%. No hemorrhages were identified in the deep white matter, basal ganglia, thalamus, or brainstem. Superficial siderosis, observed in 6 patients, did not increase the sensitivity of the Boston criteria in our study group. CONCLUSIONS Our data show that using T2*-weighted MRI and including microbleeds increase the sensitivity of the Boston criteria. The exclusion of hemorrhages in the deep white matter, basal ganglia, thalamus, and brainstem does not lower the sensitivity of the Boston criteria.

Abstract
Headache is a common, but rarely voiced, complaint during space flights, usually attributed to space motion sickness (SMS). We used a specifically designed questionnaire based on the criteria of the International Classification of Headache Disorders, 2nd edn (ICHD-II). Of the 16 male and one female astronauts who participated in the survey, 12 (71%) reported having experienced at least one headache episode while in space, whereas they had not suffered from headache when on earth. There were in total 21 space headache episodes, of moderate to severe intensity in 71%. In two astronauts (12%) the headache and associated symptoms would match the ICHD-II criteria for migraine and in three (18%) astronauts for tension-type headache; in 12 (70%) astronauts the headache was non-specific. The vast majority of headache episodes (76%) were not associated with symptoms of SMS. We conclude that space flights may trigger headaches without other SMS symptoms in otherwise ‘super-healthy’ male subjects. We propose to classify space headache as a separate entity among the secondary headaches attributed to disorders of homeostasis.

Abstract
BACKGROUND AND PURPOSE Basal total cerebral blood flow (TCBF) and cerebrovascular reactivity (CVR) are assumed to play an important role in the pathophysiology of small-vessel disease. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a unique monogenetic model to study the pathophysiology of arterial small-vessel disease. The aim of this study was to investigate the role of TCBF and CVR in the progression of MR imaging abnormalities in CADASIL. MATERIALS AND METHODS Basal TCBF was measured in 25 NOTCH3 mutation carriers and 13 control subjects at baseline. CVR after administration of acetazolamide was measured in 14 NOTCH3 mutation carriers and 9 control subjects. Increase in white matter hyperintensities (WMHs), lacunar infarcts, and microbleeds on MR imaging was measured 7 years later. RESULTS Lower CVR at baseline was associated with larger increase of WMHs (P = .001) but not with a larger increase of lacunar infarcts or microbleeds. TCBF at baseline was not associated with an increase of MR imaging abnormalities. CONCLUSIONS Decreased CVR is a potential predictor of disease progression as indicated by increasing WMHs in CADASIL.

Abstract
Resumen: La cefalea en racimos (CR) o “neuralgia de Horton”, es un tipo relativamente raro de cefalea que se presenta en forma de ataques y cuya severidad le ha dado el nombre de “dolor de cabeza suicida”. Debido a que la CR es una patología bastante desconocida, el paciente puede tardar en ser diagnosticado, especialmente debido a que es raro que un médico lo atienda en el momento mismo del ataque. La CR suele ser confundida con sinusitis, migraña o patología dental. De ahí que los pacientes no reciban el tratamiento adecuado, o lo reciban demasiado tarde. Sin embargo, la CR es fácil de diagnosticar por lo típico del cuadro clínico, y en la mayoría de los casos, también es fácil de tratar. Por ello, es importante que esta enfermedad sea reconocida lo antes posible. Los médicos de cabecera pueden jugar un importante papel en el proceso de diagnóstico.

Abstract
Background: Cognitive decline is one of the clinical hallmarks of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), a cerebrovascular disease caused by NOTCH3 mutations. In this 7-year follow-up study, we aimed to determine whether there are associations between the different radiologic hallmarks in CADASIL and decline in specific cognitive domains.Methods: Twenty-five NOTCH3 mutation carriers and 13 controls had standardized neuropsychological testing and MRI examinations at baseline and after a follow-up of 7 years. To identify longitudinal associations between MRI abnormalities and cognitive decline, correlation analysis was used.Results: At follow-up, mutation carriers showed a decline in global cognitive function (CAMCOG, p < 0.01) and in the cognitive domains language, memory, and executive function, compared to controls. Cognitive decline, especially executive dysfunction, was associated with increase in lacunar infarcts, microbleeds, and ventricular volume. In contrast, WMHs and brain atrophy were not associated with cognitive decline.Conclusion: Increase in lacunar infarcts, microbleeds, and ventricular volume, but not white matter lesions or atrophy, are associated with cognitive decline in the process of CADASIL in younger-aged, mildly affected patients with CADASIL.

Abstract
Could the novel fulfil a role in the neurologist's daily clinical practice? A good book or story can indeed make the neurology patient's experiences clearer, both for the patient and for the doctor. The novel is no longer just an end-product or form of art, but a method for better understanding disease and experiences. Several neurological examples are given, such as migraine, Parkinson's disease and ALS. The narrative opens a perspective on disease 'from the inside'. Neurology lends itself to a narrative approach, because it is primarily a field to which the patient's story is central.

Abstract
Most molecular genetic knowledge in migraine so far comes from the study of a rare subtype, familial hemiplegic migraine (FHM). The three known FHM genes (CACNA1A, ATP1A2 and SCN1A) are ion transporter genes. Mutations in all three FHM genes can also be associated with epilepsy. Of the many epilepsy genes that have been discovered, an association with migraine has been reported only for SCN1A. There is probably a lack of systematic studies of migraine in epilepsy families. A genetically determined dysfunction of ion transporters seems to point, at least to certain extent, at a common underlying mechanism for both paroxysmal disorders. The effect of ion channel mutations on neuronal neurotransmitter release is probably of major importance. In this article, we will discuss the arguments for a genetic relationship between migraine and epilepsy. A possible genetic link could give insight into the pathophysiology of both syndromes, and offer possibilities to develop specific preventive treatment aimed at the underlying ion transporter dysfunction and its consequences.

Abstract
Familial hemiplegic migraine (FHM) and alternating hemiplegia of childhood (AHC) are severe neurological disorders that share clinical features. Therefore, FHM genes are candidates for AHC. We performed mutation analysis in the CACNA1A gene in a monozygotic twin pair with clinical features overlapping with both AHC and FHM and identified a novel de novo CACNA1A mutation. We provide the first evidence that a CACNA1A mutation can cause atypical AHC, indicating an overlap of molecular mechanisms causing AHC and FHM. These results also suggest that CACNA1A mutation scanning is indicated in patients with a severe neurological phenotype that includes paroxysmal (alternating) hemiplegia.

Abstract
Premature stop codons in CACNA1A, which encodes the alpha(1A) subunit of neuronal P/Q-type (Ca(V)2.1) Ca(2+) channels, cause episodic ataxia type 2 (EA2). CACNA1A undergoes extensive alternative splicing, which contributes to the pharmacological and kinetic heterogeneity of Ca(V)2.1-mediated Ca(2+) currents. We identified three novel heterozygous stop codon mutations associated with EA2 in an alternately spliced exon (37A), which encodes part of an EF-hand motif required for Ca(2+)-dependent facilitation. One family had a C to G transversion (Y1854X). A dinucleotide deletion results in the same premature stop codon in a second family, and a further single nucleotide change leads to a different truncation (R1858X) in a de novo case of EA2. Expression studies of the Y1854X mutation revealed loss of Ca(V)2.1-mediated current. Because these mutations do not affect the alternate exon 37B, these findings reveal unexpected dependence of cerebellar function on intact exon 37A-containing Ca(V)2.1 channels.

Abstract
Of the 18 missense mutations in the CACNA1A gene, which are associated with familial hemiplegic migraine type 1 (FHM1), only mutations S218L, R583Q and T666M were identified in more than two independent families. Including the four novel families presented here, of which two represent de novo cases, the R1347Q mutation has now been identified in six families. A genotype-phenotype comparison of R1347Q mutation carriers revealed a wide clinical spectrum ranging from (trauma triggered) hemiplegic migraine with and without ataxia, loss of consciousness and epilepsy. R1347Q is the third most frequent mutation in hemiplegic migraine patients and should therefore be screened with priority for confirmation of clinical diagnosis. This study clearly demonstrates that the availability of multiple families better reflects the full clinical spectrum associated with FHM1 mutations.
