...em," Brady said. Kennedy disease is also known as spinal and bulbar muscular atrophy, or SBMA. Like the better-known ALS and Huntington's, it is a rare but devastating disease, affecting one in 40,000 people, usually between the ages of 30 and 50. Huntington's strikes about four times as many. Neurodegene...

Study offers window into human behavior, brain disease

...orate in Parkinson's disease, motor neurons of the spinal cord and motor cortex degenerate in ALS and specific memory-forming medial temporal lobe neurons die in early Alzheimer's disease. "We hope to add von Economo neurons to that list," says Seeley. "It's a pretty important list to fill in, but for FT...

Mayo Clinic study suggests that a central nervous system viral infection can lead to memory deficits
