INTRODUCTION: Migraine is a common neurological disorder characterized by a particular phenotype, complex pathophysiology and a heterogeneous genetic background. Among several heritable forms, familial hemiplegic migraine is the best described one. In the majority of cases it is caused by mutations in one of three different genes. CASE REPORT: Clinical symptoms of a 47 year old proband (and independently described in his 20 year old son) as well as differential diagnosis are discussed in the presented report...

PURPOSE OF REVIEW: This article is a practical guide to identifying uncommon causes of stroke and offers guidance for evaluation and management, even when large controlled trials are lacking in these rarer forms of stroke. RECENT FINDINGS: Fabry disease causes early-onset stroke, particularly of the vertebrobasilar system; enzyme replacement therapy should be considered in affected patients. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), often misdiagnosed as multiple sclerosis, causes migraines, early-onset lacunar strokes, and dementia...

In Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL), by contrast to sporadic cerebral small vessel disease related to age and hypertension, white matter hyperintensities (WMH) are frequently observed in the white matter of anterior temporal poles, external capsules, and superior frontal regions. Whether these WMH (specific WMH) differ from those observed in other white matter areas (nonspecific WMH) remains unknown. Twenty patients were scanned to compare specific and nonspecific WMH using high-resolution images and analyses of relaxation times (T1R: longitudinal relaxation time and T2*R: effective transversal relaxation time)...

BACKGROUND: Disease models are useful for prospective studies of pathology, identification of molecular and cellular mechanisms, pre-clinical testing of interventions, and validation of clinical biomarkers. Here, we review animal models relevant to vascular cognitive impairment (VCI). A synopsis of each model was initially presented by expert practitioners. Synopses were refined by the authors, and subsequently by the scientific committee of a recent conference (International Conference on Vascular Dementia 2015)...

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditary disease of the cerebral small blood vessels characterized by recurrent ischemic strokes, migraine, and progressive cognitive impairment. In patients with CADASIL, in whom subcortical white matter structures are typically involved, epileptic seizures have been rarely reported as an initial clinical symptom. We describe a patient genetically confirmed as having CADASIL who initially presented with a seizure...

A 68-year-old female patient was admitted in our clinic with severe frontal bilateral headache, dizziness, depression and cognitive decline in the context of a previously diagnosed acromegaly. She also had high blood pressure, dyslipidemia, secondary diabetes mellitus. Acromegaly was caused by a growth hormone (GH) secreting-pituitary macroadenoma, so a transsphenoidal surgery was performed. The postoperative magnetic resonance imaging (MRI) scan revealed a 20÷22÷25 mm pituitary mass remnant and medical therapy with somatostatin analogues (SSAs) was started...

INTRODUCTION: CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy), the most common inherited cause of stroke and dementia in adults, has been described in six Greek families. Common presenting manifestations include migraine with aura, brain ischemia, mood disorders and cognitive decline. Spontaneous intracerebral hemorrhage (SICH) rarely occurs in CADASIL and only exceptionally as the first clinical manifestation. CASE DESCRIPTION: We have previously reported the sixth Greek family with CADASIL and in particular, two brothers in whom the genetic testing documented a classic mutation of the NOTCH3 gene (Arg169Cys)...

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is characterized by cerebral infarction related to mutations in the notch homolog protein 3 (NOTCH3). We enrolled 10 patients whose brain magnetic resonance imaging (MRI) fluid-attenuated inversion recovery images showed hyperintensities (HIs) in the deep white matter and the external capsule. We then investigated the mutations in NOTCH3 using direct sequencing within the region of intron-exon boundaries in exons 2-24 of NOTCH3...

BACKGROUND: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a monogenic, hereditary, small vessel disease of the brain causing stroke and vascular dementia in adults. CADASIL has previously been shown to be caused by varying mutations in the NOTCH3 gene. The disorder is often misdiagnosed due to its significant clinical heterogeneic manifestation with familial hemiplegic migraine and several ataxia disorders as well as the location of the currently identified causative mutations...

BACKGROUND: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited cerebral microangiopathy presenting with variable features, including migraine, psychiatric disorders, stroke, and cognitive decline and variable disability. On neuroimaging, CADASIL is characterized by leukoencephalopathy, multiple lacunar infarcts, and microbleeds. Previous studies suggest a possible role of endothelial impairment in the pathogenesis of the disease...

OBJECTIVE: To determine the frequency of distinctive EGFr cysteine altering NOTCH3 mutations in the 60,706 exomes of the exome aggregation consortium (ExAC) database. METHODS: ExAC was queried for mutations distinctive for cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), namely mutations leading to a cysteine amino acid change in one of the 34 EGFr domains of NOTCH3. The genotype-phenotype correlation predicted by the ExAC data was tested in an independent cohort of Dutch CADASIL patients using quantified MRI lesions...

Despite transient global amnesia is considered unusual in Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) and causal relation is still unclear, this report suggests to consider CADASIL in those patients with recurrent transient global amnesia, especially when MRI shows multifocal hyperintensities affecting the cerebral white matter or when it is followed by cognitive decline.

CADASIL (Cerebral Autosomal Dominant Arteriopathy With Subcortical Infarcts and Leukoencephalopathy), the most frequent genetic cause of stroke and vascular dementia, is caused by highly stereotyped mutations in the NOTCH3 receptor, which is predominantly expressed in vascular smooth muscle. The well-established TgNotch3(R169C) mouse model develops characteristic features of the human disease, with deposition of NOTCH3 and other proteins, including TIMP3 (tissue inhibitor of metalloproteinase 3), on brain vessels, as well as reduced maximal dilation, and attenuated myogenic tone of cerebral arteries, but without elevated blood pressure...

BACKGROUND: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) results from NOTCH3 gene mutations, which lead to the degeneration of vascular smooth muscle cells (VSMCs). The clinical presentation of CADASIL patients is dependent on the impact of other vascular risk factors and the type of NOTCH3 mutation present. METHODS: Here, we report a rare pathogenic mutation on exon 14 of the NOTCH3 gene in a Chinese family affected by CADASIL with phenotypic peculiarities...

A 37-year-old man was hospitalized for an evaluation of acute bilateral multiple subcortical infarcts. There were no specific signal abnormalities in the temporal pole or external capsule. An abdominal skin biopsy showed granular, electron-dense, osmiophilic material (GOM) in the smooth muscle cells on electron microscopy. A direct sequencing analysis of NOTCH3 revealed a heterozygous c.986G>A substitution in exon 6, resulting in a Cys329Tyr amino acid replacement. According to these findings, the patient was diagnosed with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencehalopathy (CADASIL)...

Cerebral autosomal dominant arteriopathy and subcortical ischemic leukoencephalopathy (CADASIL) is sometimes misdiagnosed as multiple sclerosis (MS). MS and CADASIL are not known to co-occur and brain magnetic resonance imagining (MRI) findings can help with differential diagnosis. Despite the availability of this information, a case report is presented of a 61-year-old woman who was misdiagnosed with MS at age 50, tested positive for CADASIL at age 56, described incorrectly as having both conditions simultaneously, and continued on MS disease-modifying medications, resulting in financial and physical hardship...

Endothelial dysfunction (ED), in particular cerebral ED, may be an essential biomarker for ischaemic cerebrovascular disease. However, there is no consensus on methods to best estimate cerebral ED. In this systematic review, we evaluate the use of l-arginine and N(G) -monomethyl-l-arginine (l-NMMA) for assessment of cerebral ED. A systematic search of PubMed, EMBASE and the Cochrane Library was done. We included studies investigating cerebrovascular response to l-arginine or l-NMMA in human subjects with vascular risk factors or ischaemic cerebrovascular disease...
