Leukodystrophies, disorders of the white matter, with macrocephaly as a prominent feature include Canavan disease, Alexander disease, and megalencephalic leukoencephalopathy with subcortical cysts. How to Cite This Article: Shalbafan B. Alexander and Canavan Disease. Alexander disease (AxD) is a devastating childhood disease that affects neural development and causes mental retardation, seizures and spasticity. A more benign condition with megalencephaly and spongiform leukoencephalopathy has been reported with an autosomal recessive inheritance. Macrocephaly, which is characteristic of Canavan disease, can also be found in Alexander disease, Tay-Sachs disease, and other neurodegenerative disorders. Canavan disease (CD) is an autosomal recessive disorder that presents usually in the first few months of life with macrocephaly, lack of head control, hypotonia (and later spasticity,) developmental delay and seizures. Most cases of Alexander disease begin before age 2 years (the infantile form). Canavan disease is a gene-linked neurological disorder that results in brain tissue degeneration. Symptoms of the infantile form include an enlarged brain and head, seizures, stiffness … How to Cite This Article: Shalbafan B. Alexander and Canavan Disease.
