| Alzheimer's dementia | <disease> A progressive, neurodegenerative disease characterised by loss of function and death of nerve cells in several areas of the brain leading to loss of cognitive function such as memory and language. The cause of nerve cell death is unknown but the cells are recognised by the appearance of unusual helical protein filaments in the nerve cells (neurofibrillary tangles) and by degeneration in cortical regions of brain, especially frontal and temporal lobes. Alzheimer's disease is the most common cause of dementia. (22 May 1997) |
|---|---|
| vascular dementia | A state of diminished cognition that is the results from repeated cerebral strokes with a step-like deterioration in intellectual functions with focal neurological signs, as the result of multiple infarctions of the cerebral hemispheres. Synonym: multi-infarct dementia. (07 Mar 2000) |
| paralytic dementia | Dementia and paralysis resulting from a chronic syphilitic meningoencephalitis. Synonym: dementia paralytica. (05 Mar 2000) |
| catatonic dementia | Dementia with catatonic symptoms. (05 Mar 2000) |
| multi-infarct dementia | <neurology> This form of dementia is caused by a number of strokes in the brain. These strokes can cause specific symptoms, depending on their severity and location and can cause general symptoms of dementia. MID cannot be treated, once the nerve cells die, they cannot be replaced. However, the underlying condition leading to strokes (for example, high blood pressure, diabetes) can be treated, which may help prevent further damage. Synonym: vascular dementia. (22 May 1997) |
| presenile dementia | Dementia of Alzheimer's disease developing before age 65. Synonym: Alzheimer's disease. Primary dementia, dementia occurring independently as a mental disorder. (05 Mar 2000) |
| primary senile dementia | <disease> A progressive, neurodegenerative disease characterised by loss of function and death of nerve cells in several areas of the brain leading to loss of cognitive function such as memory and language. The cause of nerve cell death is unknown but the cells are recognised by the appearance of unusual helical protein filaments in the nerve cells (neurofibrillary tangles) and by degeneration in cortical regions of brain, especially frontal and temporal lobes. Alzheimer's disease is the most common cause of dementia. (22 May 1997) |
| secondary dementia | Chronic dementia following and due to a psychosis or some other underlying disease process. Senile dementia, dementia of Alzheimer's disease developing after age 65. Toxic dementia, dementia caused by an exogenous agent. (05 Mar 2000) |
| senile dementia | <neurology> A form of dementia caused by destruction (atrophy) of the frontal lobes of the brain. This condition leads to the progressive deterioration of mental functioning. Incidence: 9 out of 10,000 people in the population. (27 Sep 1997) |
| delirium, dementia, amnestic, cognitive disorders | Cognitive disorders including delirium, dementia, and other cognitive disorders. These may be the result of substance use, trauma, or other causes. (12 Dec 1998) |
| dementia | <neurology, psychiatry> An organic mental disorder characterised by a general loss of intellectual abilities involving impairment of memory, judgment and abstract thinking as well as changes in personality. It does not include loss of intellectual functioning caused by clouding of consciousness (as in delirium) nor that caused by depression or other functional mental disorder (pseudodementia). Dementia may be caused by a large number of conditions, some reversible and some progressive, that cause widespread cerebral and damage or dysfunction. The most common cause is Alzheimer's disease, others are cerebrovascular disease (multi infarct dementia), central nervous system infection, brain trauma or tumours, pernicious anaemia, folic acid deficiency, Wernicke Korsakoff syndrome, normal pressure hydrocephalus, and, neurological diseases such as Huntington disease, multiple sclerosis and Parkinson's disease.

| dementia, multi-infarct | Organic mental disorder caused by repetitive multiple cerebral infarcts which act cumulatively to produce dementia. Vascular disease is always presumed to be present. (12 Dec 1998) |
| 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) |
| dementia paralytica | Dementia and paralysis resulting from a chronic syphilitic meningoencephalitis. Synonym: dementia paralytica. (05 Mar 2000) |
| dementia paranoides | Dementia with paranoid features. Posttraumatic dementia, dementia caused by traumatic brain injury. Dementia praecox, any one of the group of psychotic disorders known as the schizophrenias; formerly used to describe schizophrenia as a single entity. Origin: L. Precocious (05 Mar 2000) |
