Canavan disease is a progressive, fatal, genetic disorder affecting the central nervous system, muscles, and eyes. Early symptoms in infancy may include increased head size, weakness, low muscle tone and loss of head control. Symptoms progress to seizures, blindness, inability to move voluntarily and difficulty eating solids or swallowing liquids. This condition is caused by changes in the ASPA gene and is inherited in an autosomal recessive pattern. Canavan disease is diagnosed based on symptoms, laboratory testing, and genetic testing. There is no specific treatment. Treatment is focused on managing symptoms.
