From the Guidelines
The management of CADASIL should focus on counseling on smoking cessation and treatment of hypertension and other vascular risk factors to reduce the risk of incident stroke, as recommended by the 2024 guideline from the American Heart Association/American Stroke Association 1.
Key Management Strategies
- Counseling on smoking cessation is beneficial to reduce the risk of incident stroke in patients with CADASIL 1.
- Treatment of hypertension and other vascular risk factors is crucial to reduce the risk of incident stroke in patients with CADASIL 1.
- While there is no disease-modifying treatment for CADASIL, managing symptoms and preventing stroke-like episodes are essential.
- Lifestyle modifications, including limited alcohol consumption, regular physical activity, and maintaining a healthy diet, are important for overall health and may help reduce symptom burden.
- Genetic counseling should be offered to patients and families due to the autosomal dominant inheritance pattern of CADASIL.
Symptom Management
- Migraine, a common symptom of CADASIL, can be treated with standard migraine medications, though vasoconstrictors like triptans should be used cautiously 1.
- Depression and anxiety may require antidepressants, with SSRIs often preferred.
- Cognitive decline can be addressed with acetylcholinesterase inhibitors like donepezil or rivastigmine in some cases.
- Seizures, if present, require appropriate anticonvulsant therapy.
Monitoring and Follow-up
- Regular follow-up with a neurologist is essential to monitor disease progression and adjust management strategies.
- This multifaceted approach aims to reduce symptom burden and improve quality of life, as CADASIL is a progressive condition caused by mutations in the NOTCH3 gene affecting small blood vessels in the brain.
From the Research
Management of CADASIL
The management of Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) is primarily focused on relieving symptoms, as there is currently no evidence-based treatment available 2.
Current Treatment Approaches
- Relief of symptoms such as migraine, mood disorders, and cognitive decline is the primary goal of treatment 2.
- No specific therapy is available to halt the progression of the disease 3.
- Management may involve addressing individual symptoms, such as treating migraine and mood disorders, and providing support for cognitive decline and dementia 4, 5.
Diagnostic Considerations
- Diagnosis can be made based on characteristic white matter hyperintensities on magnetic resonance imaging (MRI) and the presence of pathognomonic granular osmiophilic material in arterial walls, including dermal arteries 4, 3.
- Genetic testing for mutations in the Notch3 gene can also be used to confirm diagnosis 4, 3.
Clinical Features and Prognosis
- CADASIL typically begins with migraine in about one-third of patients, followed by more severe manifestations such as transient ischemic attacks or recurrent strokes between 30 and 50 years of age 4, 3.
- The disease leads to cognitive decline and dementia of the subcortical vascular type, with multiple lacunar infarcts located mainly in the basal ganglia and frontal white matter 4, 3.
