Abstract
BACKGROUND Cerebral small vessel disease (CSVD) is common among the elderly and has been associated with an increased risk of major adverse cardiac events (MACE) and increased risk of long-term disability. Little is known whether CSVD affects outcomes after cervicocerebral artery dissection (CAD), which predominantly affects younger patients. Specifically, there is a paucity as to whether CSVD increases the risk of MACE after CAD and whether this risk is different for early versus late events. METHODS We retrospectively analyzed 140 consecutive patients with acute CAD. We determined CSVD on MRI using the STRIVE criteria and calculated the CSVD sum score based on the individual CSVD components. For statistical analysis the CSVD burden was dichotomized to mild (score 0-1) versus severe (score 2-4). The primary outcome of interest was the 6-month MACE risk. Secondary outcomes of interest were early versus late MACE, stroke at presentation, and good 90-day outcome (modified Rankin Scale score 0-2). RESULTS There was no difference in overall MACE between subjects when stratified by CSVD burden (10.1% versus 9.8%, Log-rank P = 0.953). We found that patients with severe CSVD had significantly more late MACE as compared to mild CSVD (9.8% versus 1.1%, P = 0.024). There was no significant difference in the prevalence of stroke at the time of CAD diagnosis (50.6% versus 47.1%, P = 0.690) and the 90-day disability-free survival in subjects with mild versus severe CSVD (93.7% versus 91.7%, P = 0.729). CONCLUSION Severe CSVD burden was associated with a significantly greater risk of late MACE. CSVD assessment in CAD patients may aid risk stratification and treatment optimization.

Abstract
BACKGROUND: Ichthyosis vulgaris is the most common type of Mendelian disorders of cornification, caused by loss-of-function mutations in the gene encoding epidermal protein filaggrin (FLG), namely R501X and 2282del4. FLG 2282del4 mutation in heterozygotes is incompletely penetrant. Polymorphisms in one-carbon metabolism genes could be associated with clinical manifestation of ichthyosis vulgaris.
AIM: The purpose of the present study was to analyze the effects of MTHFR, MTR and MTRR polymorphisms in patients with ichthyosis vulgaris.
METHODS: 31 patients with ichthyosis vulgaris, 7 their FLG heterozygous relatives without symptoms of disorder, and 150 healthy controls were enrolled in study. FLG null mutations —R501X (rs61816761) and 2282del4 (rs558269137) — and one-carbon metabolism gene polymorphisms — MTHFR C677T (rs1801133), MTHFR A1298C (rs1801131), MTR A2756G (rs1805087) and MTRR A66G (rs1801394) — were analyzed by a polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) assay.
RESULTS: Among patients with ichthyosis, heterozygous for FLG 2282del4 mutation, the distributions of genotypes for folate metabolism genes were: MTHFR C677T CC:CT:TT —29.4%:70.6%:0.0%; MTHFR A1298C AA:AC:CC — 52.9%:47.1%:0.0%; MTR A2756G AA:AG:GG — 70.3%:23.5%:5.9%; MTRR A66G AA:AG:GG — 23.4%:52.9%:23.5%. The frequencies of MTR 2756AA and MTRR 66GG genotypes were 1.4–1.6 times higher in affected individuals heterozygous for 2282del4 than in patients with other FLG genotypes. In affected 2282del4 heterozygotes, the frequency of MTR 2756AA genotype was 1.6 times greater than in healthy controls (p<0.01). The strongest association was found between MTHFR 677CT/MTHFR 1298AA/MTR 2756AA/MTRR 66AG genotype and ichthyosis — OR=11.23 (95% CI 2.51−50.21, p=0.002).
CONCLUSIONS: Various genotypes of one-carbon metabolism genes increase the risk of ichthyosis in heterozygotes for the FLG 2282del4 mutation (OR 2.799‑11.231). The most probable predisposing genotype is 677CT/1298AA/2756AA+AG/66AG.

Abstract
Cervicocerebral artery dissection (CAD) is one of the more frequent causes of stroke in young adults with rates of up to 25%. Predisposing and risk factors for CAD are very different, and an etiological classification is based on the presence of a previous minor or major trauma, differentiating traumatic from spontaneous CAD. Headache represents one of the main initial symptoms for this pathological condition, probably due to the release of pro-inflammatory neurotransmitters from nerve terminals near the injured vessel. For its peculiar characteristics, the headache due to CAD has been defined with specific ICHD-3 criteria. In many cases, headache is associated with other signs related to the dissection or cerebral ischemia. In this systematic review of literature, headache was reported in more than 70% of cases with CAD with a prevalence in vertebrobasilar dissections. More than half of patients suffered a severe pain that was usually located in fronto-temporal and occipito-nuchal regions in the case of dissections in the anterior and posterior circulation, respectively. For the high stroke risk, CAD has to be promptly diagnosed with MRI or CTA and treated with anticoagulants or antithrombotics.

Abstract
Spontaneous cervical artery dissection (sCAD) is a major cause of stroke in young adults. Multiple sCAD is a rarer, more poorly understood presentation of sCAD that has been increasingly attributed to cervical trauma such as spinal manipulation or genetic polymorphisms in extracellular matrix components. The authors present the case of a 49-year-old, otherwise healthy woman, who over the course of 2 weeks developed progressive, hemodynamically significant, bilateral internal carotid artery and vertebral artery dissections. Collateral response involved extensive external carotid artery–internal carotid artery anastomoses via the ophthalmic artery, which were instrumental in maintaining perfusion because circle of Willis and leptomeningeal anastomotic responses were hampered by the dissection burden in the corresponding collateral vessels. Endovascular intervention by placement of Pipeline embolization devices and Atlas stents in bilateral internal carotid arteries was successfully performed. No syndromic or systemic etiology was discovered during a thorough workup.

Abstract
Spontaneous cervico-cerebral artery dissection (CCAD) is a common condition found among young patients with ischemic stroke. We examined the possible association between the polymorphism of methylenetetrahydrofolate reductase (MTHFR)-C677T and the gene mutation in transforming growth factor beta receptor II (TGFBR2) in a cohort of CCAD patients. One-hundred CCAD cases (65 males; mean age: 38.08 ± 10.68 years) and 100 matching controls were included. Ancestry informative markers (AIMs) were used to increase internal validity of the genetic analysis. Genotypes of the C677T polymorphism in the MTHFR gene were determined by polymerase chain reaction and restriction fragment length polymorphism; direct sequencing was used for a mutation analysis of the TGFBR2 gene. Associations were evaluated using a multivariate statistics, and Hardy-Weinberg equilibrium was analyzed. We also incorporated our data into a meta-analysis of the MTHFR-C677T. Sixty-three patients presented with vertebral and 37 with carotid artery dissection. Ancestry markers found a call rate on each over 95 %. All AIMs did not deviate from Hardy-Weinberg equilibrium (p > 0.05). The homozygous TT genotype was more frequent in cases (OR 2.04, CI 95 % 1.53-2.72, p = 0.005), whereas no significant difference was found on heterozygous CT genotype. TGFBR2 mutation was not present in our samples. In the meta-analysis of MTHFR/C677T variant, a total 613 cases and 1547 controls were analyzed; we found a moderate association for the recessive model genotype (OR 2.04, CI 95 % 1.53-2.72; p = 0.342; Z = 4.83; I (2) = 11.3). This study supports a positive association between the MTHFR-C677T polymorphism and genetically confirmed Mexican mestizo CCAD patients.

Abstract
BACKGROUND Cervical artery dissection (CAD) is a recognized cause of ischemic stroke. Hyperhomocysteinemia (HHcy), i.e. an elevated concentration of plasma homocysteine, is identified as an independent risk factor for stroke prevalence. However, an association between HHcy and CAD has so far remained unknown. METHODS A meta-analysis was performed to analyze the association between HHcy and CAD as well as the relevance of the C677T polymorphism of methylenetetrahydrofolate reductase (MTHFR), the key enzyme in homocysteine metabolism during CAD. We searched PubMed and Embase for studies reporting homocysteine concentrations or MTHFR genotype frequencies in CAD patients from 1990 to 2013. Outcomes were extracted from studies meeting the inclusion criteria and were subjected to a meta-analysis by the random-effect model. Heterogeneity was assessed by the I(2) test. RESULTS Eight case-control studies with 2,146 individuals fulfilled the required criteria and were included in the meta-analysis. HHcy was found to be significantly associated with CAD (pooled standardized mean difference: 0.96; 95% confidence interval, CI: 0.42-1.49; p < 0.01). We also found a significantly increased risk of CAD in individuals with the MTHFR C677T polymorphism by both the recessive model (TT vs. CT+CC; odds ratio, OR = 1.81; 95% CI: 1.22-2.67; p = 0.003) and the dominant model (TT+CT vs. CC; OR = 1.47; 95% CI: 1.08-1.99; p = 0.014). CONCLUSION Our data suggest positive correlations between HHcy and CAD and between the C677T polymorphism of MTHFR and CAD.

Abstract
The etiology of cervical artery dissection (CAD) is unclear, although a number of risk factors have been reported to be associated with the condition. On rare occasions, patients experience CAD after cervical spine manipulation, making knowledge about the cervical arteries, the predisposing factors, and the pathogenesis of the condition of interest to chiropractors. This commentary reports on the relevant anatomy of the cervical arteries, developmental features of CAD, epidemiology of the condition, and mechanisms of dissection. The analysis of CAD risk factors is confusing, however, because many people are exposed to mechanical events and known pathophysiological associations without ever experiencing dissection. No cause-and-effect relationship has been established between cervical spine manipulation and CAD, but it seems that cervical manipulation may be capable of triggering dissection in a susceptible patient or contributing to the evolution of an already existing CAD. Despite the many risk factors that have been proposed as possible causes of CAD, it is still unknown which of them actually predispose patients to CAD after cervical spine manipulation.

Abstract
INTRODUCTION Cervical artery dissection is a major cause of cerebral ischemia in young adults and can lead to various clinical symptoms, some of which are benign (e.g. headache, neck pain, Horner's syndrome, and cranial nerve palsy). However, most patients have a stroke or transient ischemic attack. EPIDEMIOLOGY The incidence of cervical artery dissection is low and is estimated to be around 2.6 per 100,000 inhabitants. Mortality and short-term recurrence rates are low: however; they may have been underestimated. PATHOPHYSIOLOGY Although the pathophysiology is still unclear constitutional and partly genetic susceptibility of the arterial wall has been proposed as a causal factor; triggered by infection or minor trauma. PREDISPOSING FACTORS: In addition to the trauma to the neck, other risk fractors have been suggested, such as infection, migraine, hyperhomocisteinamia, and the 67TT genotype of the 5,10-methylene-tetrahydrofolate reductase gene although evidence is sparse. GENETIC FACTORS Cervical artery dissection is now considered a multifactorial disease caused by several genetic abnormalities and environmental factors acting synergistically. CONCLUSION Research aimed at improving our understanding of the environmental and genetic factors predisposing to cervical artery dissection and assessment of long-term outcomes of this disease is needed. Better understanding of the underlying pathophysiology and the natural history of the disease through large prospective multicentre cohorts could also be helpful to improve therapeutic and preventive strategies. Several mutlticentre efforts are already under way to meet these needs.

Abstract
In spite of the strong epidemiologic evidence linking migraine and ischemic stroke in young adults, the mechanisms explaining this association remain poorly understood. The observation that stroke occurs more frequently during the interictal phase of migraine prompts to speculation that an indirect relation between the two diseases might exist. In this regard, four major issues might be considered which may be summarized as follows: (1) the migraine-ischemic stroke relation is influenced by specific risk factors such as patent foramen ovale or endothelial dysfunction and more frequent in particular conditions like spontaneous cervical artery dissection; (2) migraine is associated with an increased prevalence of cardiovascular risk factors; (3) the link is caused by migraine-specific drugs; (4) migraine and ischemic vascular events are linked via a genetic component. In the present paper, we will review epidemiological studies, discuss potential mechanisms of migraine-induced stroke and comorbid ischemic stroke, and pose new research questions.

Abstract
Dementia, stroke and migraine are very common neurological disorders affecting a large percentage of the population, and leading to a high degree of disability. Often, adequate therapy is not available. Although the symptoms, the progression and the outcome differ in these disorders, to some extent they may share some common pathophysiological mechanisms. The genetic background, an energy deficit, and excitotoxicity, vascular and thrombotic properties can influence all three disorders, resulting in a neuronal dysfunction, increased cellular vulnerability, neurodegeneration and ultimately cell death. All these cellular events occur in dementias and stroke, moreover recent studies suggest that, besides a dysfunction, neuronal damage may be an issue in migraine too. One of the most central events in the multiple mechanisms involved in the pathogenesis of these disorders is a metabolic disturbance of certain brain cells. As mitochondria provide the cells with energy, realization of the importance of these organelles in the aetiopathogenesis of several disorders has emerged in recent years. This review surveys the most important features of the pathogenesis of dementia, stroke and migraine from the aspect of mitochondrial malfunction highlighting some of the considerable connections between these neurological disorders.

Abstract
Aims The pathogenesis of spontaneous cervical artery dissection remains unknown. We examined the association between different polymorphisms frequently found in young patients with cryptogenic stroke [methylenetetrahydrofolate reductase ( MTHFR) C677T, factor II (prothrombin) G20210A, factor V G1691A (Leiden), nitric oxide synthase 3 ( NOS3) intron 4 VNTR, and apolipoprotein E ( APOE) ε4 gene] in patients with a cerebral infarct caused by spontaneous cervical artery dissection. Methods Forty-eight patients (27 males) and 96 matching control subjects were recruited. Clinical history, including cardiovascular risk factors, was assessed in all subjects. Genotypes were determined by a polymerase chain reaction with and without a restriction fragment length polymorphism. The genotypes and allele frequencies of the five genetic variants studied were compared between spontaneous cervical artery dissection cases and controls. We also incorporated our data into a meta-analysis of the MTHFR/C677T variant. Results Of 48 patients with spontaneous cervical artery dissection (28 vertebral and 20 carotid), the mean age of the patients was 36·6 ± SD 9·9 years. There were no significant associations between the alleles of the five genetic polymorphisms studied and spontaneous cervical artery dissection. In the meta-analysis of the MTHFR/C677T variant, a total of 564 individuals (231 cases and 333 controls) were analysed; no significant association was observed. Conclusions The results from this exploratory case-control study show the lack of an association between MTHFR, factor II G20210A, factor V G1691A, NOS3, intron 4 VNTR, and APOE ε4 gene polymorphisms and the development of spontaneous cervical artery dissection. Our findings contribute towards a better understanding of the genetic risk factors associated with spontaneous cervical artery dissection.

Abstract
Cervical-artery dissection (CAD) is a major cause of cerebral ischaemia in young adults and can lead to various clinical symptoms, some of which are benign (eg, headache, neck pain, Horner's syndrome, and cranial-nerve palsy), but most patients have a stroke or transient ischaemic attack. In addition to trauma to the neck, other risk factors have been suggested, such as infection, migraine, hyperhomocysteinaemia, and the 677TT genotype of the 5,10-methylenetetrahydrofolate reductase gene (MTHFR 677TT), although evidence is sparse. An underlying arteriopathy, which could in part be genetically determined, is believed to have a role in the development of CAD. Importantly, both research on and optimum management of CAD strongly rely on diagnostic accuracy. Although the functional outcome of CAD is good in most patients, socioprofessional effects can be important. Incidence of the disorder in the general population is underestimated. Mortality and short-term recurrence rates are low but possibly also underestimated. Further research is warranted to improve our understanding of the underlying pathophysiology, to assess the long-term outcome, and ultimately to provide treatment and prevention strategies.

Abstract
Background Cervical artery dissection (CAD) is a frequent cause of ischemic stroke, and occasionally death, in young adults. Several lines of evidence suggest a genetic predisposition to CAD. However, previous genetic studies have been inconclusive mainly due to insufficient numbers of patients. Our hypothesis is that CAD is a multifactorial disease caused by yet largely unidentified genetic variants and environmental factors, which may interact. Our aim is to identify genetic variants associated with an increased risk of CAD and possibly gene-environment interactions. Methods We organized a multinational European network, Cervical Artery Dissection and Ischemic Stroke Patients (CADISP), which aims at increasing our knowledge of the pathophysiological mechanisms of this disease in a large group of patients. Within this network, we are aiming to perform a de novo genetic association analysis using both a genome-wide and a candidate gene approach. For this purpose, DNA from approximately 1100 patients with CAD, and 2000 healthy controls is being collected. In addition, detailed clinical, laboratory, diagnostic, therapeutic, and outcome data are being collected from all participants applying predefined criteria and definitions in a standardized way. We are expecting to reach the above numbers of subjects by early 2009. Conclusions We present the strategy of a collaborative project searching for the genetic risk factors of CAD. The CADISP network will provide detailed and novel data on environmental risk factors and genetic susceptibility to CAD.

Abstract
BACKGROUND AND PURPOSE The pathophysiology of cervical artery dissections (CAD), a major cause of ischemic stroke in young adults, is poorly understood. Several arguments suggest a genetic predisposition. METHODS We systematically reviewed all published data on genetic risk factors for CAD and performed a meta-analysis of association studies with the MTHFR C677T polymorphism. RESULTS Rarely, CAD is associated with a known monogenic connective tissue disease, mainly vascular Ehlers-Danlos syndrome. However, in the large majority of CAD cases, there is no evidence for a known monogenic disease. Several arguments, including the association of CAD with dermal connective tissue abnormalities that are inherited, suggest that genetic factors also play a role in "sporadic" CAD as part of a multifactorial predisposition. We identified 15 genetic association studies: 10 were negative and 5 reported associations of 3 genetic variants in 3 different candidate genes. Two studies reported associations with polymorphisms in ICAM-1 and COL3A1, but neither has been replicated. Three studies reported an association with the MTHFR 677TT genotype, but 3 other studies did not replicate this. A meta-analysis of these data identified an overall significant association of the MTHFR 677TT genotype with CAD (OR, 1.67; 95% CI, 1.21 to 2.31). We also identified 9 studies screening candidate genes for mutations and 4 linkage studies, yielding mostly negative results. CONCLUSIONS Although several interesting hypotheses were generated, the majority of genetic studies in CAD have been negative until now, but they were markedly underpowered. Progress in unraveling the genetics of CAD will require the collection of DNA samples from large multicenter series.

Abstract
Numerous epidemiologic observations reporting high prevalence of migraine among young individuals with stroke as well as dysfunction of cerebral arteries during migraine attacks prompt speculation on the existence of a comorbidity between the two disorders. The recent finding of silent infarct-like brain lesions in migraineurs reinforced this hypothesis and raised questions on whether migraine may be a progressive disorder rather than simply an episodic disorder. Stroke can occur during the course of migraine attacks with aura, supporting the assumption of a causal relation between the two diseases. Migraine may accentuate other existing risk factors for stroke, and both jointly increase the risk of cerebral ischemia outside of migraine attacks. In this regard, the role of migraine might be that of predisposing condition for cerebral ischemia. Migraine and ischemic stroke may be the end phenotype of common pathogenic mechanisms. Evidence of a migraine-stroke relation in cases of specific disorders, such as CADASIL (cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy) and MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes), strongly supports this concept. Finally, acute focal cerebral ischemia can trigger migraine attacks, and, thus, migraine may be the consequence of stroke. In this paper, we will review contemporary epidemiologic studies, discuss potential mechanisms of migraine-induced stroke and comorbid ischemic stroke, and pose new research questions.

Abstract
Background and Purpose—
Genetic risk factors are thought to play a role in the etiology of spontaneous cervical artery dissections (CAD). However, familial CAD is extremely rare. In this study we analyzed patients with familial CAD and asked the question whether familial CAD has particular features.
Methods—
Seven families with 15 CAD patients were recruited. All patients were carefully investigated by a neurologist, a neuroradiologist, and a dermatologist for clinical characteristics. From 11 patients a skin biopsy was performed to study the morphology of the connective tissue and to analyze the coding sequences of COL3A1, COL5A1, COL5A2, and part of COL1A1.
Results—
The mean age of the patients (n=15, 9 women) at their first dissection was 36.2 years (median age 32 years, range 18 to 59). Two patients had bilateral CAD. One patient had a right and a left internal carotid artery dissection in successive weeks, another patient had 5 dissections over a period of 8 years. A high intrafamilial correlation was found between the affected vessels (ie, the carotid and the vertebral arteries) and between ages at the first dissection. In 1 patient we found clear and reproducible ultrastructural abnormalities in the skin biopsy, but the second patient from the family was not studied, because he died as a result of CAD before this study. The dermal connective tissue aberrations in the examined patient were similar to mild findings in patients with vascular Ehlers-Danlos syndrome (EDS type IV), but might be iatrogenic and related to long-term corticosteroid inhalation therapy. All other analyzed patients showed normal connective tissue morphology. In patients from 6 families we analyzed the whole coding sequence of COL3A1, COL5A1, and COL5A2, and from part of COL1A1. A missense mutation in the COL3A1 gene (leading to a G157S substitution in type III procollagen) was detected in both patients from 1e family. Two patients from another family carried a rare nonsynonymous coding polymorphism in COL5A1 (D192N); 1 of them carried also a rare variant in COL5A2 (T12337).
Conclusions—
Familial CAD patients are young and probably are at high risk for recurrent or multiple CAD. Ultrastructural alterations of the dermal connective tissue might not be an important risk factor for familial CAD. However, the finding of a COL3A1 mutation revealed the presence of an inherited connective tissue disorder in 1 family.
