Is the thalamus affected by cadasil?

Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) is a hereditary condition that affects the blood vessels in the brain. It is characterized by the accumulation of a protein called NOTCH3 in the walls of small arteries, which leads to narrowing of the vessels and reduced blood flow to the brain. This can cause a variety of symptoms, including:

- Strokes

- Headaches

- Seizures

- Difficulty with movement and coordination

- Cognitive impairment

- Mood disorders

The thalamus is a small structure located in the center of the brain. It is involved in a variety of functions, including:

- Relaying sensory information to the cerebral cortex

- Controlling movement

- Regulating sleep and wakefulness

- Memory formation

In CADASIL, the thalamus can be affected by reduced blood flow from the small arteries that supply it. This can lead to damage to the thalamus and its associated functions. Symptoms of thalamic involvement in CADASIL can include:

- Difficulty with movement and coordination

- Tremor

- Speech problems

- Memory loss

- Difficulty with attention and concentration

- Sleep problems

The severity of thalamic involvement in CADASIL can vary from person to person. Some people may experience only mild symptoms, while others may have more severe symptoms that significantly affect their quality of life.
