Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL): a case report with review of literature. (1/101)
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL) is an inherited arterial disease, commonly overlooked or misdiagnosed. We report a case of CADASIL in a 51 years old woman who presented with progressive subcortical dementia, recurrent ischemic events and seizures in the absence of known vascular risk factors of five years' duration. Her mother had a history of similar illness. Magnetic resonance imaging (MRI) of brain revealed subcortical and deep white matter hyperintense lesions within the cerebral white matter on T2-weighted images. DNA mutation of Notch 3 gene confirmed the diagnosis of CADASIL. (+info)Long-term prognosis and causes of death in CADASIL: a retrospective study in 411 patients. (2/101)
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditary angiopathy caused by mutations in the NOTCH3 gene. The clinical course is highly variable. Little is known about the long-term prognosis and the causes of death in CADASIL patients. Likewise, the impact of gender and NOTCH3 genotype on disease progression remains largely unexplored. We identified 411 subjects (196 men, 215 women) with a definite diagnosis of CADASIL. Age at onset for stroke, immobilization and death as well as the causes of death and clinical status at onset of the cause of death were determined systematically. Weibull regression models were used to calculate times to event, with gender and NOTCH3 genotype as covariates. At the time of the study, 73 patients had died. The median age at onset for stroke was 50.7 years [95% confidence interval (CI) = 48.2-53.1 years] in men and 52.5 years (95% CI = 50.0-54.9 years) in women (P = n.s.). The median ages at onset for inability to walk without assistance [men 58.9 years (95% CI = 56.6-61.3 years); women 62.1 years (59.7-64.4 years)], bedriddenness [men 62.1 years (59.6-64.7 years), women 66.5 years (63.9-69.1 years); and death [men 64.6 years (61.7-67.6 years); women 70.7 years (67.6-73.9 years)] were significantly lower in men than in women (all P < or = 0.01). The median survival time of men was significantly shorter than expected from German life tables (64.6 versus 69.3 years, P = 0.01). In contrast, the median survival time of women was not significantly reduced (70.7 versus 72.2 years). The C117F mutation was associated with a lower age at death and the C174Y mutation with a lower age at onset for stroke, immobilization and death (adjusted P values <0.05). At onset of the cause of death, 78% of the subjects were completely dependent. Sixty-three per cent were confined to bed. Pneumonia was the most frequent cause of death (38%), followed by sudden unexpected death (26%) and asphyxia (12%). We conclude that male sex is a risk factor for early immobilization and death in CADASIL. Our findings suggest possible genotype-phenotype correlations with regard to disease progression. The data presented may serve as source material for counselling CADASIL patients and for designing future interventional trials. (+info)Detection of the founder effect in Finnish CADASIL families. (3/101)
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited cerebrovascular disease characterized by brain infarcts, cognitive decline and dementia. The disease is caused by at least 91 missense mutations, four deletions and one splice site mutation in the NOTCH3 gene, which maps to 19p13.1. In 18 out of the 21 Finnish CADASIL families so far identified, the causative mutation is an arginine to cysteine substitution in position 133 (R133C). Most of the families carrying this mutation originate from the western coast of Finland, thus suggesting a founder effect. No previous reports of a founder effect in CADASIL have been published. We haplotyped 60 patients from these 18 families for 10 microsatellite markers in order to determine whether the families descend from a common ancestor. We found a similar haplotype linked to the mutation in all 18 pedigrees, which indicates a single common ancestor for all the Finnish R133C families. The age analysis of the founder mutation places the introduction of the mutation in the late 1600s or early 1700s.

BACKGROUND AND PURPOSE: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a progressive systemic nonatherosclerotic angiopathy which causes ischemic strokes and vascular subcortical dementia. A cross-sectional study was performed to examine the retinal vascular caliber and blood flow in CADASIL. METHODS: Scanning laser Doppler flowmetry was used in a case-control study (11 patients and controls) of peripapillary retinal circulation. Automated full-field perfusion image analysis was used to analyze the flow data. Retinal vessel calibers were measured from retinal images acquired with scanning laser ophthalmoscopy. The caliber of the superior and inferior temporal retinal artery and vein were measured 1 and 2 mm from the disc rim, and the mean values were used for analysis. RESULTS: Retinal capillary peak systolic flow (mean, 249 versus 311 arbitrary unit [AU]; P=0.072) was lower, and mean capillary flow (mean, 184 versus 224 AU; P=0.12) and minimum diastolic flow (mean, 105 versus 132 AU; P=0.16) tended to be lower in patients than in controls. No significant difference in the calibers of proximal retinal arteries (mean, 104 versus 108 microm) and veins (mean, 150 versus 145 microm) was found between the patients and controls. CONCLUSIONS: Retinal capillary blood flow is mild to moderately reduced in CADASIL but that does not appear to cause major ischemic injury. Such reduction is analogous to that in the cerebral cortex in CADASIL patients with which retina appears to share its relative sparing from severe arterial ischemic tissue damage.

BACKGROUND AND PURPOSE: CADASIL is an inherited small-vessel disease responsible for lacunar strokes and cognitive impairment. The disease is caused by highly stereotyped mutations in Notch3, the expression of which is highly restricted to vascular smooth muscle cells (VSMCs). The underlying vasculopathy is characterized by degeneration of VSMCs and the accumulation of granular osmiophilic material (GOM) and Notch3 protein within the cell surface of these cells. In this study, we assessed early functional changes related to the expression of mutant Notch3 in resistance arteries. METHODS: Vasomotor function was examined in vitro in arteries from transgenic mice that express a mutant Notch3 in VSMC. Tail artery segments from transgenic and normal wild-type male mice were mounted on small-vessel arteriographs, and reactivity to mechanical (flow and pressure) forces and pharmacological stimuli were determined. Mice were studied at 10 to 11 months of age when VSMC degeneration, GOM deposits, and Notch3 accumulation were not yet present. RESULTS: Passive arterial diameter, contraction to phenylephrine, and endothelium-dependent relaxation to acetylcholine were unaffected in transgenic mice. By contrast, flow-induced dilation was significantly decreased and pressure-induced myogenic tone significantly increased in arteries from transgenic mice compared with wild-type mice. CONCLUSIONS: This is the first study to our knowledge providing evidence that mutant Notch3 impairs selectively the response of resistance arteries to flow and pressure. The data suggest an early role of vascular dysfunction in the pathogenic process of the disease.

BACKGROUND AND PURPOSE: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited small vessel disease causing stroke and dementia. The disease is caused by highly stereotyped mutations in NOTCH3, which is restrictively expressed in vascular smooth muscle cells (VSMCs). The mechanisms of compromised cerebral hemodynamics in CADASIL remain to be elucidated. We tested the hypothesis that mutant NOTCH3 impairs the vasomotor function of cerebral vessels. METHODS: Vasomotor function was examined in vivo in transgenic mice expressing a mutant NOTCH3 in VSMCs (TgNotch3R90C). Mice develop an age-dependent arteriopathy similar to that seen in CADASIL, without brain parenchyma lesions. Using laser-Doppler flowmetry, we assessed in awake TgNotch3R90C mice and wild-type littermates the cerebrovascular reactivity to 2 potent vasodilator stimuli (acetazolamide and hypercapnia) and cerebral blood flow (CBF) autoregulation during stepwise blood pressure elevations and reductions. Mice were studied at 18 months of age, when the CADASIL features are apparent, and at 10 months of age, before their appearance. RESULTS: Eighteen-month-old TgNotch3R90C mice showed reduced responses to hypercapnia and acetazolamide, higher cerebrovascular resistance during hypertension, and their lower limit of CBF autoregulation was shifted to higher blood pressures. Cerebrovascular responses were similarly impaired in 10-month-old TgNotch3R90C mice. CONCLUSIONS: Cerebrovascular reactivity is compromised early in TgNotch3R90C mice. The data show an impaired autoregulation and are suggestive of a decreased relaxation or increased resistance of cerebral vessels. Our findings indicate that vascular dysfunction is an early pathogenic event that may promote the subsequent development of brain ischemia in CADASIL. (+info)The spectrum of Notch3 mutations in 28 Italian CADASIL families. (7/101)
BACKGROUND: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL) is a cause of hereditary cerebrovascular disease. It results from mutations in the Notch3 gene, a large gene with 33 exons. A cluster of mutations around exons 3 and 4 was originally reported and limited scanning of these exons was suggested for the diagnosis in most cases. OBJECTIVE: To report Notch3 mutation analysis in 28 unrelated Italian CADASIL families from central and south Italy. RESULTS: The highest rate of mutations was found in exon 11 (21%) and only 18% of mutations were in exon 4. This may be related to the peculiar distribution of Notch3 mutations in the regions of origin of the families. CONCLUSIONS: The results suggest that limited scanning of exons 3 and 4 is inadvisable in CADASIL cases of Italian origin. (+info)The prevalence of cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL) in the west of Scotland. (8/101)
BACKGROUND: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL) is caused by mutations of the Notch3 gene on 19p13. Varying phenotypic expression leads to under recognition and misdiagnosis. Prevalence therefore remains uncertain. We sought to estimate the prevalence of CADASIL in the west of Scotland. METHODS: A register for CADASIL was established at a regional neurosciences centre in 2002. All patients with genetically (exons 3, 4, 5, and 6) or histologically confirmed CADASIL residing in two defined administrative health areas were identified. Pedigree members at varying risk of carrying the mutation were also identified and the number of probable Notch3 mutation carriers in the defined population was predicted. Prevalence was calculated for definite CADASIL cases, with and without probable carrier numbers, based upon adult population figures from the 2002 national census. RESULTS: Twenty two individuals from seven pedigrees with confirmed CADASIL and resident in the defined geographical area were identified, yielding a prevalence of 1.98 (95% confidence interval 1.24-3.00) per 100 000 adults. An additional 37 individuals were predicted to be carriers of the Notch3 mutation, yielding a probable mutation prevalence of 4.14 (3.04-5.53) per 100,000 adults. CONCLUSIONS: The prevalence of genetically proven CADASIL was 1.98 per 100,000 adults in the defined population. This figure underestimates disease burden. (+info)CADASIL (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy) is a genetic disorder that affects the small blood vessels in the brain. It is caused by mutations in the NOTCH3 gene, which leads to the progressive degeneration of these vessels.
The symptoms of CADASIL typically begin in middle age and include migraine with aura, recurrent strokes or transient ischemic attacks (TIAs), cognitive decline, and psychiatric symptoms such as depression and apathy. The condition can also cause physical disabilities such as difficulty walking and urinary incontinence.
CADASIL is an inherited disorder, meaning that it is passed down from parent to child through a mutated gene. If one parent has the disease, each child has a 50% chance of inheriting the mutated gene and developing the condition. Currently, there is no cure for CADASIL, but treatments can help manage symptoms and improve quality of life.
Multi-infarct dementia (MID) is a specific type of dementia that is caused by multiple small strokes or mini-strokes (known as transient ischemic attacks or TIAs) in the brain. Also known as vascular dementia, multi-infarct dementia results from the interruption of blood flow to parts of the brain, leading to damage and death of brain tissue.
The term 'multi-infarct' refers to multiple areas (or infarcts) of damaged or dead tissue in the brain due to the lack of oxygen and nutrients caused by these small strokes. Over time, as more areas of the brain are affected, cognitive decline becomes apparent, leading to symptoms such as memory loss, difficulty with problem-solving, disorientation, language problems, and changes in mood or behavior.
Multi-infarct dementia is typically a progressive condition, meaning that symptoms worsen over time. However, the rate of progression can vary depending on factors such as the number and severity of strokes, underlying medical conditions, and lifestyle factors. It's important to note that multi-infarct dementia can be prevented or delayed by controlling risk factors for stroke, such as high blood pressure, diabetes, smoking, and high cholesterol.
Notch receptors are a type of transmembrane receptor proteins that play crucial roles in cell-cell communication and regulation of various biological processes, including cell fate determination, differentiation, proliferation, and apoptosis. These receptors are highly conserved across species and are essential for normal development and tissue homeostasis.
The Notch signaling pathway is initiated when the extracellular domain of a Notch receptor on one cell interacts with its ligand (such as Delta or Jagged) on an adjacent cell. This interaction triggers a series of proteolytic cleavage events that release the intracellular domain of the Notch receptor, which then translocates to the nucleus and regulates gene expression by interacting with transcription factors like CSL (CBF1/RBP-Jκ/Su(H)/Lag-1).
There are four known Notch receptors in humans (Notch1-4) that share a similar structure, consisting of an extracellular domain containing multiple epidermal growth factor (EGF)-like repeats, a transmembrane domain, and an intracellular domain. Mutations or dysregulation of the Notch signaling pathway have been implicated in various human diseases, including cancer, cardiovascular disorders, and developmental abnormalities.
"Migraine with Aura" is a neurological condition that is formally defined by the International Classification of Headache Disorders (ICHD) as follows:
"An migraine attack with focal neurological symptoms that usually develop gradually over 5 to 20 minutes and last for less than 60 minutes. Motor weakness is not a feature of the aura."
The symptoms of an aura may include visual disturbances such as flickering lights, zigzag lines, or blind spots; sensory disturbances such as tingling or numbness in the face, arms, or legs; and speech or language difficulties. These symptoms are caused by abnormal electrical activity in the brain and typically precede or accompany a migraine headache, although they can also occur without a headache.
It's important to note that not all people who experience migraines will have an aura, and some people may have an aura without a headache. If you are experiencing symptoms of a migraine with aura or any other type of headache, it is recommended that you consult with a healthcare professional for proper diagnosis and treatment.
Vascular dementia is a type of dementia that is caused by damage to the blood vessels that supply blood to the brain. This damage can result from conditions such as stroke, chronic high blood pressure, diabetes, or other diseases that affect the circulatory system. The interruption in blood flow to the brain can lead to damaged or dead brain cells, which can impair cognitive function and cause symptoms similar to those seen in other types of dementia, such as Alzheimer's disease.
The symptoms of vascular dementia can vary depending on the severity and location of the damage to the blood vessels. However, common symptoms include difficulties with memory, attention, and decision-making; problems with language and speech; changes in mood or behavior; and difficulty walking or performing other physical tasks. Vascular dementia is typically a progressive condition, meaning that the symptoms tend to worsen over time.
It's important to note that vascular dementia can coexist with other types of dementia, such as Alzheimer's disease, and this is known as mixed dementia. Proper diagnosis and management of underlying medical conditions that contribute to vascular dementia can help slow down the progression of cognitive decline and improve quality of life for individuals living with this condition.
Cell surface receptors, also known as membrane receptors, are proteins located on the cell membrane that bind to specific molecules outside the cell, known as ligands. These receptors play a crucial role in signal transduction, which is the process of converting an extracellular signal into an intracellular response.
Cell surface receptors can be classified into several categories based on their structure and mechanism of action, including:
1. Ion channel receptors: These receptors contain a pore that opens to allow ions to flow across the cell membrane when they bind to their ligands. This ion flux can directly activate or inhibit various cellular processes.
2. G protein-coupled receptors (GPCRs): These receptors consist of seven transmembrane domains and are associated with heterotrimeric G proteins that modulate intracellular signaling pathways upon ligand binding.
3. Enzyme-linked receptors: These receptors possess an intrinsic enzymatic activity or are linked to an enzyme, which becomes activated when the receptor binds to its ligand. This activation can lead to the initiation of various signaling cascades within the cell.
4. Receptor tyrosine kinases (RTKs): These receptors contain intracellular tyrosine kinase domains that become activated upon ligand binding, leading to the phosphorylation and activation of downstream signaling molecules.
5. Integrins: These receptors are transmembrane proteins that mediate cell-cell or cell-matrix interactions by binding to extracellular matrix proteins or counter-receptors on adjacent cells. They play essential roles in cell adhesion, migration, and survival.
Cell surface receptors are involved in various physiological processes, including neurotransmission, hormone signaling, immune response, and cell growth and differentiation. Dysregulation of these receptors can contribute to the development of numerous diseases, such as cancer, diabetes, and neurological disorders.
Medical Definition:
Magnetic Resonance Imaging (MRI) is a non-invasive diagnostic imaging technique that uses a strong magnetic field and radio waves to create detailed cross-sectional or three-dimensional images of the internal structures of the body. The patient lies within a large, cylindrical magnet, and the scanner detects changes in the direction of the magnetic field caused by protons in the body. These changes are then converted into detailed images that help medical professionals to diagnose and monitor various medical conditions, such as tumors, injuries, or diseases affecting the brain, spinal cord, heart, blood vessels, joints, and other internal organs. MRI does not use radiation like computed tomography (CT) scans.

Patients8
- Control of high blood pressure is particularly important in CADASIL patients. (wikipedia.org)
- Short-term use of atorvastatin, a statin-type cholesterol-lowering medication, has not been shown to be beneficial in CADASIL patients' cerebral hemodynamic parameters, although treatment of comorbidities such as high cholesterol is recommended. (wikipedia.org)
- In one small study, around 1/3 of patients with CADASIL were found to have cerebral microhemorrhages (tiny areas of old blood) on MRI. (wikipedia.org)
- The exact mortality rate in patients with CADASIL is unknown. (medscape.com)

- CADASIL patients are also at increased risk of heart attack (myocardial infarction) because of involvement of the blood vessels in the heart. (goldbamboo.com)
- CONCLUSION: CADASIL cases are rare and only detected in SVD patients with confluent leukoaraiosis. (ox.ac.uk)
- Methods We performed a genome-wide association study to identify quantitative trait loci for WMH volume by combining data from 517 CADASIL patients collected through 7 centers across Europe. (mpg.de)
Findings1
- Our findings suggest that multiple variants with small effects influence WMH burden in CADASIL. (mpg.de)
Atorvastatin1

Treatment1
- No specific treatment for CADASIL is available. (wikipedia.org)
People1
- As with other individuals, people with CADASIL should be encouraged to quit smoking. (wikipedia.org)
White matter1
- When white matter abnormalities are absent on MRI of a person older than 35 years of age, CADASIL is usually excluded. (wikibooks.org)
Subjects1
- Conclusions We found a polygenic score to be associated with WMH volume in CADASIL subjects. (mpg.de)
Normal1
