It can cause paranoid and grandiose delusions, agitation, hallucinations (visual and auditory), bizarre behavior, fear, short-term memory loss, and confusion.HIV encephalopathy can lead to dementia. Types
There are many 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, usually caused by prenatal exposure to ethanol. Uremic encephalopathy: Arising from high levels of toxins normally cleared by the kidneys—rare where dialysis is readily available. Wernickes encephalopathy: Arising from thiamine (B1) deficiency, usually in the setting of alcoholism. Hashimotos encephalopathy: Arising from an auto-immune disorder. Anti-NMDA receptor encephalitis: An auto-immune encephalitis. Hyperammonemia: a condition caused by high levels of ammonia, which is due to inborn errors of metabolism (including urea cycle disorder or multiple carboxylase deficiency), a diet with excessive levels of protein, deficiencies of specific nutrients such as  arginine or biotin, or organ failure. Hypertensive encephalopathy: Arising from acutely increased blood pressure. Chronic traumatic encephalopathy: a progressive degenerative disease associated with multiple concussions and other forms of brain injury
Lyme encephalopathy: Arising from Lyme disease bacteria, including Borrelia burgdorferi. Toxic encephalopathy: A form of encephalopathy caused by chemicals and prescription drugs, often resulting in permanent brain damage.
These advances have led to increasingly extensive research into the proteins involved with the disease, potential drug treatments, care methods, and the gene itself.The condition was formerly called Huntingtons chorea, but this term has been replaced by Huntingtons disease because not all patients develop chorea and due to the importance of cognitive and behavioral problems. Society and culture
Ethics
Genetic testing for Huntingtons disease has raised several ethical issues. The issues for genetic testing include defining how mature an individual should be before being considered eligible for testing, ensuring the confidentiality of results, and whether companies should be allowed to use test results for decisions on employment, life insurance or other financial matters. There was controversy when Charles Davenport proposed in 1910 that compulsory sterilization and immigration control be used for people with certain diseases, including HD, as part of the eugenics movement. In vitro fertilization has some issues regarding its use of embryos. Some HD research has ethical issues due to its use of animal testing and embryonic stem cells.The development of an accurate diagnostic test for Huntingtons disease has caused social, legal, and ethical concerns over access to and use of a persons results. Many guidelines and testing procedures have strict procedures for disclosure and confidentiality to allow individuals to decide when and how to receive their results and also to whom the results are made available. Insurance companies and businesses are faced with the question of whether to use genetic test results when assessing an individual, such as for life insurance or employment.
