  Brain Disorders
Some brain disorders are congenital. Tay-Sachs disease, Fragile X syndrome, Down syndrome, and Tourette syndrome are all linked to genetic or chromosomal errors. Malfunctions in the embryonic development of the brain can be caused by genetic factors or by drug use or disease in the mother.

Other problems in the brain can be more accurately classified as diseases rather than injuries. Neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, motor neurone disease, and Huntington's disease, are caused by the gradual death of individual neurons leading to decrements in movement control, memory, and thinking abilities.

Currently, only the symptoms of these diseases can be treated, but stem cell research may offer a cure. Mental illnesses, such as clinical depression, schizophrenia, bipolar disorder, and post-traumatic stress disorder, are theorized as having a biological basis in the brain.

These disorders may be treated by psychiatric therapy, by drugs, or by a combination of treatments, but the effectiveness of the therapy varies with the individual and any comorbid organic diseases.

Some infectious diseases affecting the brain are caused by viral or bacterial infection(s). Infection of the meninges, the membrane that covers the brain, can lead to meningitis. Bovine spongiform encephalopathy, also known as mad cow disease, is a deadly disease among cattle and is linked to prions.

Kuru is a similar prion-borne degenerative brain disease affecting humans. Both are linked to the ingestion of neural tissue from animals of the same species, and are often theorized to be an evolutionary defense against cannibalism. Viral or bacteria causes have been substantiated in multiple sclerosis, Parkinson's disease, and Lyme disease, as well as in encephalopathy and encephalomyelitis.
