Name any deficiency disease caused by lack of vitamin E?

Ataxia with Vitamin E Deficiency (AVED) is a rare neurological condition caused by a deficiency of vitamin E. Vitamin E is an essential nutrient for the body that helps to protect cells from damage. In AVED, the lack of vitamin E leads to damage to the nervous system, particularly in the cerebellum, which is responsible for coordination and balance. Symptoms of AVED can include difficulty walking, slurred speech, problems with vision, and muscle weakness. Treatment for AVED involves taking high doses of vitamin E supplements to help improve symptoms and prevent further damage.
