Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) is a rare hereditary form of stroke. It is a genetic condition characterised by a number of small strokes.

Many people also experience migraines which can affect their speech and vision for a short time and cause numbness down one side of the body.

Cognitive problems may develop over time as the condition progresses, often when a person is in their 50s or 60s. It has a dominant inheritance pattern which means there is a 50/50 chance of inheriting the faulty gene from a parent with CADASIL. It is very rare and affects around 1,200 people in the UK.
