Disease, damage, or malfunction of the brain. In general, encephalopathy is manifested by an altered mental state that is sometimes accompanied by physical changes. Although numerous causes of encephalopathy are known, the majority of cases arise from infection, liver damage, anoxia, or kidney failure. The term encephalopathy is very broad and, in [..]

MELAS is the acronym for Mitochondrial Encephalopathy, Lactic Acidosis, and Strokelike episodes. MELAS is a form of dementia.
