CADASIL 1

CADASIL (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy) is a rare inherited disorder that affects the small blood vessels in the brain.

• Definition: CADASIL is a hereditary, autosomal-dominant, small-artery vasculopathy caused by mutations in the NOTCH3 gene on chromosome 19q13.1 [3].
• Symptoms: The disease is characterized by migraine headaches and multiple strokes progressing to dementia. Other symptoms include cognitive deterioration, seizures, vision changes, and mood disorders [5].
• Age of onset: The age at onset can vary, but it typically starts in the fourth or fifth decade of life [14].

CADASIL is a progressive disorder that affects the small blood vessels in the brain, leading to damage and degeneration of the surrounding tissue. It is considered one of the most common genetic causes of stroke and dementia in adults.

[5] CADASIL is characterized by migraine headaches and multiple strokes progressing to dementia. Other symptoms include cognitive deterioration, seizures, vision changes, and mood disorders [6]. [14] Clinical Description. CADASIL is a disease of the small to medium-sized arteries, mainly affecting the brain. The presenting symptoms, age at onset, and disease progression in CADASIL are variable, both between and within families [14].

CADASIL Signs and Symptoms

CADASIL, or Cerebral Autosomal Dominant Arteriopathy with Subacute Infarcts and Leukoencephalopathy, is a rare genetic disorder that affects the blood vessels in the brain. The signs and symptoms of CADASIL can vary from person to person, but they often include:

• Recurrent strokes: Strokes are a common symptom of CADASIL, and they can occur at any age [1].
• Cognitive impairment: People with CADASIL may experience memory problems, difficulty with thinking and problem-solving, and other cognitive issues [2].
• Migraine with aura: Migraines are a common symptom of CADASIL, and they often involve throbbing pain, nausea, sensitivity to light and sound [8].
• Psychiatric disturbances: Some people with CADASIL may experience anxiety, depression, or other psychiatric symptoms [3].
• Headaches: Headaches are a frequent symptom of CADASIL, and they can be severe [9].
• Vision disturbances: People with CADASIL may experience vision problems, such as blurred vision or loss of vision [6].
• Numbness: Numbness or tingling sensations in the face, arms, or legs can also occur [5].
• Speech disturbances: Some people with CADASIL may experience slurred speech or difficulty speaking [5].

These symptoms can start at any age, but they often begin in the 30s-50s. Early symptoms of CADASIL may include muscle tone increases, stroke episodes, muscle spasms, and worsening movement problems [5]. If you are experiencing any of these symptoms, it is essential to consult with a healthcare professional for proper diagnosis and treatment.

Diagnostic Tests for CADASIL

CADASIL (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy) is a rare inherited disease that affects the blood vessels in the brain. Diagnosing CADASIL can be challenging, but several diagnostic tests are available to confirm the condition.

Genetic Testing

Genetic testing is a crucial component in diagnosing CADASIL. It involves analyzing DNA samples from patients and their family members to identify mutations in the NOTCH3 gene [6][12]. This test can confirm the presence of pathogenic variants in the NOTCH3 gene, which is responsible for CADASIL.

Skin Biopsy

A skin biopsy may be performed if genetic testing has been negative or inconclusive. Electron microscopy of skin biopsies from CADASIL patients can reveal characteristic changes in the blood vessels [14].

MRI and Radiographic Findings

Magnetic Resonance Imaging (MRI) scans can show white matter changes characteristic of CADASIL, which can aid in diagnosis [13]. However, these findings alone are not sufficient to confirm the condition.

Clinical Diagnosis

CADASIL can only be diagnosed clinically through a combination of family history, MRI findings, and NOTCH3 genetic testing. The hallmark symptoms of CADASIL include recurrent strokes, cognitive decline, and migraine headaches [9].

Other Diagnostic Tests

While not specific to CADASIL, other diagnostic tests may be used to rule out other conditions that present similar symptoms. For example, electron microscopy can help diagnose Fabry disease, an X-linked disorder caused by deficiency in α-galactosidase A [15].

In summary, diagnosing CADASIL requires a combination of genetic testing, skin biopsy, MRI findings, and clinical evaluation. While these tests can confirm the presence of CADASIL, they should be interpreted in conjunction with family history and other relevant factors.

[13] Diagnosis generally occurs through a combination of family history of migraines/strokes/dementia, MRI findings of white matter changes characteristic of CADASIL and NOTCH3 genetic testing.

[14] Prior to the availability of a genetic test and sometimes still used for diagnostic confirmation, electron microscopy of skin biopsies from CADASIL patients can reveal characteristic changes in the blood vessels.

Current Status of Drug Treatment for CADASIL

CADASIL, or Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy, is a rare inherited disease that affects the blood vessels in the brain. Unfortunately, there is no specific treatment available for CADASIL at this time.

Management of Symptoms

While there is no cure or effective treatment for CADASIL, various medications may be used to manage its symptoms. These include:

• Anti-hypertensive medications: To control high blood pressure,

The differential diagnosis of CADASIL (Cerebral Autosomal Dominant Arteriopathy With Subcortical Infarcts and Leukoencephalopathy) is a crucial aspect of diagnosing this condition. Here are some key points to consider:

• Multiple sclerosis: CADASIL can be confused with multiple sclerosis due to similar clinical presentations, such as recurrent transient ischemic attacks and cognitive decline [7].
• Binswanger disease: This condition, also known as subcortical vascular dementia, shares similarities with CADASIL in terms of its impact on the brain's white matter [6].
• Primary angiitis of the central nervous system: This rare condition can present with similar symptoms to CADASIL, including recurrent strokes and cognitive decline [5].
• Other genetic disorders: The differential diagnosis of CADASIL also includes other genetic disorders that affect the brain, such as demyelinating disorders [4].

It's worth noting that the clinical presentation of CADASIL can vary widely, making it challenging to diagnose. However, by considering these potential differential diagnoses, healthcare providers can narrow down the possibilities and arrive at a more accurate diagnosis.
