CADASIL (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy) is a hereditary small vessel disease caused by NOTCH3 mutations. Treatment focuses on stroke prevention, symptom management, and lifestyle modifications, as no disease-modifying therapy exists currently. [@cadasil2023]

Antiplatelet Therapy

Aspirin and Antiplatelet Agents

Antiplatelet therapy is a cornerstone of CADASIL management to reduce ischemic stroke risk:

• Low-dose aspirin (81-100 mg daily) is commonly prescribed for primary and secondary stroke prevention [@antiplatelet2013](https://pubmed.ncbi.nlm.nih.gov/23435542/)
• Clopidogrel may be used in patients who cannot tolerate aspirin
• Dipyridamole combined with aspirin has been studied but evidence specific to CADASIL is limited
• Dual antiplatelet therapy (aspirin + clopidogrel) may be considered after an acute ischemic event, but bleeding risk must be carefully evaluated

Important Considerations

CADASIL (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy) is a hereditary small vessel disease caused by NOTCH3 mutations. Treatment focuses on stroke prevention, symptom management, and lifestyle modifications, as no disease-modifying therapy exists currently. [@cadasil2023]

Antiplatelet Therapy

Aspirin and Antiplatelet Agents

Antiplatelet therapy is a cornerstone of CADASIL management to reduce ischemic stroke risk:

• Low-dose aspirin (81-100 mg daily) is commonly prescribed for primary and secondary stroke prevention [@antiplatelet2013](https://pubmed.ncbi.nlm.nih.gov/23435542/)
• Clopidogrel may be used in patients who cannot tolerate aspirin
• Dipyridamole combined with aspirin has been studied but evidence specific to CADASIL is limited
• Dual antiplatelet therapy (aspirin + clopidogrel) may be considered after an acute ischemic event, but bleeding risk must be carefully evaluated

Important Considerations

• Antiplatelet therapy should be individualized based on stroke history, bleeding risk, and comorbidities
• Some CADASIL patients may have increased susceptibility to intracranial hemorrhage, particularly with cerebral microbleeds on MRI [@cerebral2018](https://pubmed.ncbi.nlm.nih.gov/29878275/)

Vascular Risk Factor Management

Blood Pressure Control

Rigorous blood pressure control is essential:

• Target blood pressure: <130/80 mmHg according to most guidelines
• First-line agents: ACE inhibitors, ARBs, calcium channel blockers
• Avoid excessive hypotension which may worsen cerebral hypoperfusion
• Regular monitoring and aggressive treatment of hypertension

Other Vascular Risk Factors

• Hyperlipidemia: Statin therapy may be considered [@statin2018](https://pubmed.ncbi.nlm.nih.gov/28742511/)
• Diabetes management: Tight glycemic control
• Smoking cessation: Absolute contraindication
• Alcohol moderation: Limited alcohol intake
• Weight management: Maintain healthy BMI

Migraine Management

Migraine with aura is a common presenting symptom in CADASIL:

Acute Treatment

• Triptans (sumatriptan, rizatriptan) may be used with caution
• NSAIDs (ibuprofen, naproxen) for acute attacks
• Antiemetics (metoclopramide) for associated nausea

Preventive Treatment

• Beta-blockers (propranolol, metoprolol) - first-line prophylactic agents
• Topiramate - effective for migraine prevention
• Amitriptyline - tricyclic antidepressant with migraine prophylactic properties
• CGRP inhibitors (erenumab, fremanezumab) - newer options with emerging evidence [@cgrp2020](https://pubmed.ncbi.nlm.nih.gov/33201245/)

Important Notes

• Avoid estrogen-containing contraceptives due to increased stroke risk
• Migraine aura may be triggered by certain medications or dehydration

Cognitive Decline Prevention

Pharmacological Approaches

No treatments are FDA-approved specifically for CADASIL-related cognitive decline, but the following may help:

• [Cholinesterase inhibitors](/entities/cholinesterase-inhibitors) ([donepezil](/entities/donepezil), rivastigmine) - modest benefit in some patients
• Memantine - [NMDA receptor](/entities/nmda-receptor) antagonist may provide cognitive benefits
• Vitamin B supplementation if deficiency is present

Non-Pharmacological Approaches

• Cognitive rehabilitation and mental stimulation
• Physical exercise - regular aerobic activity
• Social engagement and occupational therapy
• Sleep hygiene - addressing sleep disorders

Psychiatric Symptoms

Mood and behavioral changes are common in CADASIL:

• Selective serotonin reuptake inhibitors (SSRIs) for depression and anxiety
• Sertraline, citalopram, or escitalopram are commonly used
• Atypical antipsychotics (quetiapine) for severe behavioral changes - use with caution due to stroke risk

Symptomatic Treatments

Stroke/Transient Ischemic Attack

• Immediate medical evaluation required
• Consider thrombolysis if within appropriate time window
• Antiplatelet therapy intensification may be needed

Seizures

• Antiepileptic drugs (levetiracetam, lamotrigine)
• Avoid drugs that lower seizure threshold

Emerging Therapies

Disease-Modifying Approaches

• NOTCH3-targeted therapies are under investigation [@notchtargeted2018](https://pubmed.ncbi.nlm.nih.gov/30392477/)
• Gene therapy approaches targeting NOTCH3 expression
• Stem cell therapies for vascular regeneration

Clinical Trials

Several clinical trials are investigating novel therapeutics:

• Agents targeting Notch3 signaling pathway
• Vascular protective agents
• Cerebral vasodilators

Lifestyle and Supportive Care

Physical Activity

• Regular aerobic exercise (walking, swimming, cycling)
• Aim for 150 minutes of moderate-intensity exercise per week
• Balance and gait training if needed

Diet

• Mediterranean diet - associated with reduced cardiovascular risk
• Low sodium intake for blood pressure control
• Adequate hydration

Monitoring and Follow-Up

• Regular neurological examinations
• Annual MRI to monitor disease progression
• Neuropsychological testing for cognitive assessment
• Cardiac evaluation if needed

Support Systems

• Patient education and genetic counseling
• Support groups for CADASIL patients
• Occupational therapy for independence maintenance
• Caregiver support and education
