Types of encephalopathy.

Some examples include:

•Mitochondrial encephalopathy: Metabolic disorder caused by dysfunction of mitochondrial DNA. Can affect many body systems, particularly the brain and nervous system.

•Glycine encephalopathy: A genetic metabolic disorder involving excess production of glycine

•Hepatic encephalopathy: Arising from advanced cirrhosis of the liver

•Hypoxic ischemic encephalopathy: Permanent or transitory encephalopathy arising from severely reduced oxygen delivery to the brain

•Static encephalopathy: Unchanging, or permanent, brain damage

•Uremic encephalopathy: Arising from high levels of toxins normally cleared by the kidneys—rare where dialysis is readily available

•Wernicke's encephalopathy: Arising from thiamine deficiency, usually in the setting of alcoholism

•Hashimoto's encephalopathy: Arising from an auto-immune disorder

•Hypertensive encephalopathy: Arising from acutely increased blood pressure

•Chronic traumatic encephalopathy: Progressive degenerative disease associated with multiple concussions and other forms of head injury

•Lyme encephalopathy: Arising from Lyme disease bacteria, including Borrelia burgdorferi.

•Toxic encephalopathy: A form of encephalopathy caused by chemicals, often resulting in permanent brain damage

•Toxic-Metabolic encephalopathy: A catch-all for brain dysfunction caused by infection, organ failure, or intoxication

•Transmissible spongiform encephalopathy: A collection of diseases all caused by prions, and characterized by "spongy" brain tissue (riddled with holes), impaired locomotion or coordination, and a 100% mortality rate. Includes bovine spongiform encephalopathy (mad cow disease), scrapie, and kuru among others.

•Neonatal encephalopathy: An obstetric form, often occurring due to lack of oxygen in bloodflow to brain-tissue of the fetus during labour or delivery

•Salmonella encephalopathy : A form of encephalopathy caused by food poisoning (especially out of peanuts and rotten meat) often resulting in permanent brain damage and nervous system disorders.

•Encephalomyopathy: A combination of encephalopathy and myopathy. Causes may include mitochondrial disease (particularly MELAS) or chronic hypophosphatemia, as may occur in cystinosis.
