Dementias are classified by commonality of affected part of brain or of symptoms or by the speed of onset and progress or one or more of these.
Progressive dementias (so far neither reversible nor stoppable).
- ALZHEIMER’s disease. Generally developing after age 60, Alzheimer’s is the most common cause of dementia, early-onset caused by defective gene. Often related to sugar imbalance and diabetes;
- VASCULAR DEMENTIA, the second most common type of progressive dementia, occurs as a result of brain damage , multiple strokes and paralysis (relate to imbalance of sugar or cholesterol). Blood flow in blood vessels leading to your brain are reduced or blocked;
- LEWY BODY DEMENTIA affects approximately 10 percent of patients. More common with age and has symptoms similar Alzheimer’s. Its unique features include fluctuations between confusion and lucidity, visual hallucinations and parkinsonism;
- FRONTOTEMPORAL DEMENTIA. Characterized by the breakdown of nerve cells in the frontal and temporal brain, tends to occur at a younger age than does Alzheimer’s. It affects personality, behavior and language.
Disorders linked to but are not dementias:
- HUNTINGTON’S DISEASE. Nerve cells in the brain and spinal cord waste away, causing personality changes. Hereditary.
- CREUTZFELDT-JAKOB DISEASE. A rare brain disorder, without risk factors. Develops when prions cause normal proteins in the brain to start folding into abnormal shapes. Same symptoms as dementia. Sudden onset and worsens very quickly. Inherited or caused by exposure to diseased brain or nervous system tissue. Can be treated by draining the extra fluid from the brain into the abdomen.
- PARKINSON’S DISEASE. Eventually develops into dementia symptoms.
- GSS (Gerstmann-Straussler-Scheinker syndrome) too, is an Inherited, Prion disease.
- HIV-associated dementia. It is not yet known what the virus does to the brain.
- WERNICKE-KORSAKOFF SYNDROME, which is most often caused by alcohol misuse.
