What are the forms of dementia?

Alzheimer's disease is one form of dementia. Dementia is the significant cognitive impairment in at least one of the following cognitive domains: learning and memory, language, executive function, complex attention, perceptual-motor function and social cognition. Other forms of dementia include frontotemporal dementia, vascular dementia, Parkinson's disease with dementia, and dementia with Lewy bodies.
Dementia is a general term used to describe cognitive deficits. Just as there are many types of cars, there also are many types of dementia, with Alzheimer’s being one of the most common. Other common types include vascular dementia, which is caused by stroke, and mixed dementia, which is a combination of the two.

Do not automatically assume that a dementia diagnosis is Alzheimer’s disease. This is such a well-known household term nowadays that many people - including doctors - are biased toward making this diagnosis.

But, there are a surprising number of other dementias, including:
  • Mild cognitive impairment (MCI)
  • Vascular dementia
  • Mixed dementia
  • Dementia with Lewy bodies
  • Parkinson’s disease
  • Frontotemporal dementia (Pick’s disease, a rare front temporal neurodegenerative-disease)
  • Creutzfeldt-Jakob disease (CJD)
  • Normal-pressure hydrocephalus
  • Huntington’s disease
  • Wernicke-Korsakoff syndrome

- Vascular dementia, which is caused by brain damage from cerebrovascular or cardiovascular problems such as strokes, heart problems, and genetic diseases.
- Lewy body dementia, a progressive dementia linked to the abnormal protein present in Parkinson's disease.
- Frontotemporal dementia, in which nerve cells in the frontal and temporal lobes of the brain deteriorate.
- HIV-associated dementia, which occurs in people with HIV.
- Huntington's disease, a hereditary disorder caused by a faulty gene, which causes degeneration in many regions of the brain and spinal cord.
- Dementia pugilistica, which results from repeated head trauma.
- Corticobasal degeneration, a progressive disorder linked to the accumulation of an abnormal protein in the brain.
- Secondary dementias, dementia that occurs in patients with disorders that primarily affect movement – Parkinson's disease, multiple sclerosis, motor neuron diseases such as amyotrophic lateral sclerosis (Lou Gehrig's disease), olivopontocerebellar atrophy, Wilson's disease, and normal pressure hydrocephalus.
