| dementia-nuchal dystonia | A disorder that is associated with nerve cell destruction and progressive lack of coordination, neck stiffness, trunk stiffness, problems with eye movement and mild dementia. Disorders that are similar include Alzheimer's disease, cerebellar dysfunction, Jakob-Creutzfeldt disease and Parkinson's disease. The cause for progressive supranuclear palsy is unknown, but is likely a degenerative nerve disorder that is somehow triggered by a viral infection. Pathologic changes include nerve cell damage and destruction of myelin sheath. There is no known cure. (27 Sep 1997) |

| dialysis dementia | A progressive (often fatal) diffuse encephalopathy which occurs in a few patients who undergo chronic haemodialysis, dementia is a key feature (27 Sep 1997) |
| transmissible dementia | <infectious disease> A very rare form of encephalopathy thought to be caused by a virus (slow-virus), termed a prion. There is little known about the mode of transmission. Human to human transmission has occurred through the use of contaminated brain electrodes and transplantation of infected tissues. The agent can be recovered in the CSF of infected individuals. Standard disinfectants such as formalin, heat, exposure to ultraviolet light or X-rays is ineffective to inactivate the virus. Autoclaving to at least 132 degrees C. Or immersion in 4% sodium hydroxide or 10% sodium hypochlorite solution for 1 hour is recommended for sterilisation. The disease occurs primarily in adults, with peak incidence in the late 50's. Infection results in dementia, myoclonus, ataxia and other neurologic symptoms. The disease progresses rapidly to coma and death after a 3 to 12 month illness. There is no known cure. (27 Sep 1997) |
| epileptic dementia | Dementia occurring in an individual afflicted with epilepsy, and thought to be a result of prolonged seizures, the epileptogenic brain lesion, or antiepileptic drugs. Hebephrenic dementia, dementia with hebephrenic symptoms. (05 Mar 2000) |
