B) Alexander Disease

This answer is incorrect.

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.  (See References)

C) Devic's Syndrome

This answer is incorrect.

Devic's Syndrome is a variant of multiple sclerosis (MS), in which optic neuritis and transverse myelitis occur together, or at least within weeks of each other. The transverse myelitis frequently leads to necrosis, and is thus more permanent than the usual transverse myelitis associated with MS. It also differs from MS in that the lesions are often limited to those described above, and the rest of the CNS is spared. Serologic finidngs are also frequently different from those of MS, e.g., no oligoclonal bands.  (See References)

E) Korsakoff's Amnesic Syndrome

This answer is incorrect.

Korsakoff's Amnesic Syndrome is a syndrome of severe anterograde and retrograde amnesia. It is often associated with polyenuropathy. It is frequently associated with a thiamine deficiency secondary to alcoholism or malnutrition, with lesions of the mammillary bodies visible on pathology or MRI. It can have other etiologies, including ischemic lesions in various parts of the brain.   (See References)
