Riley-Day Syndrome is a congenital, autosomal recessive disease which predominately affects Jewish children. Failure to thrive and fever are early signs. Hyporeflexia and decreased pain & temperature sensation are noted on exam. There is also poor function of the autonomic nervous system. The standard test is for dopamine B-hydroxylase, which is diminished. (

Alexander Disease is a rare, congenital disease which does not appear to be inherited. No metabolic cause has been found. Clinical features include seizures, psychomotor retardation, and failure to thrive, followed by progressive macrocephaly. The frontal lobes show white matter degeneration, and pathology shows Rosenthal fibers found near the pia and blood vessels, these are thought to be detritus from glial destruction. (

This answer is incorrect.
Korsakoff's Amnesic Syndrome is a syndrome of severe anterograde and retrograde amnesia. It is often associated with polyenuropathy.

It can have other etiologies, including ischemic lesions in various parts of the brain. (
