What is CADASIL?

When the walls of blood vessels become hardened, it blocks the blood supply to the brain, which causes CADASIL, a rare hereditary disease. The term CADASIL is an abbreviation for "cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy."

Even though the symptoms and development of the disorder may vary in different people, symptoms usually start to appear between the ages of 20 and 40. For some individuals, the symptoms may not even appear until much later in life. Symptoms may sometimes begin during childhood, although this is relatively rare.

What are the symptoms of CADASIL?

Common symptoms of CADASIL are:

• Aura-associated migraine migraines
• Multiple strokes that cause dementia
• Acute encephalopathy that can occur with CADASIL can include confusion or coma.
• Gradual impairment of cognitive and memory skills
• Psychiatric illnesses include bipolar disorder, depression, and abulia

The following are less common symptoms of CADASIL:

• Seizures
• Vision problems
• Shakiness and slow movements (parkinsonism)
• weakness or numbness
• Rapidly appearing abnormal gait, nausea, and vomiting

The symptoms usually start slow. Most individuals with CADASIL will have dementia or cognitive deficit by age 65.

Who has a higher risk of developing CADASIL?

Any individual can develop CADASIL. The condition occurs worldwide, equally affects both sexes, and can occur in anyone of any race or ethnicity.

The mutation that causes CADASIL is found in the Notch3 gene. Tiny blood capillaries in the white matter of the brain are affected by this mutation. Often, the illness is familial, but it can also be the consequence of a spontaneous genetic mutation which has not yet been identified.

How is CADASIL diagnosed?

A physician will make a diagnosis of CADASIL based on the symptoms of the patient, the family history, and brain abnormalities identified by an MRI. Such could include the following:

• Strokes that take place in the region of the brain below the cortex, called subcortical strokes
• Changes in the white matter of the brain
• Cerebral microbleeds are small segments of bleeding.
• Atrophy of the brain

However, these individual brain changes may not be unique and may be replicated in other forms of the disease as well.

A clinician can also confirm a patient with CADASIL through:

• Genetic tests: A genetic blood test assessing the inheritance of disorder of Notch3.
• Skin biopsy: The blood vessel of other portions of the body, such as epidermal changes due to CADASIL.

How is CADASIL treated?

There is no effective treatment for CADASIL available currently. On the other hand, considering its increased risk of stroke, it is important to take preventive steps against stroke by people suffering from CADASIL. These involve managing high blood pressure, cholesterol, and glucose, and possibly antiplatelet therapy in certain cases, anticoagulation drugs that impede the aggregative activity of blood cells such as platelets, preventing the formation of clots within blood vessels. Patients with CADASIL must avoid smoking; smoking can enhance the risk for stroke. A doctor can offer more direction on these. Also, the frequency of which symptoms occur allows people with CADASIL with migraines to be treated by medications and education and avoidance of migraine triggers. Treatment for depression should also be provided to those who suffer from it.

Supportive care such as assistance in daily activities, emotional support and counselling may benefit those with CADASIL as well as their families.

What can my loved one or I do to improve care for individuals with CADASIL?

To educate the physicians and the researchers about CADASIL, consider joining a clinical trial. Clinical studies using human subjects have the potential of making the investigator understand an illness better and discover possibly safer prevention, detection, or treatment methodologies for diseases.

Different ages, sexes, races, and ethnicities of participants, who are healthy or potentially unhealthy or diseased, are needed to ensure that the results obtained from the study can be applicable to the majority of people and that the treatment is safe and effective for all users.
