你说的也对.查了一下:

 

Types of dementia(主要的有三种):

1. Alzheimer's disease:

 Alzheimer's disease is the most common form of dementia, accounting for two-thirds of all diagnosed cases. If your dementia symptoms are the result of Alzheimer's disease, medications can delay the onset of more debilitating symptoms. Early diagnosis can prolong independence and is the first step towards treatment, management, and living life fully.

2. Vascular dementia:

Vascular dementia results from a series of small strokes or changes in the brain's blood supply. Sudden onset of symptoms may be a sign of this dementia. Vascular dementia severely impacts memory and cognitive functioning. However, there are ways to prevent and reduce its severity.

3. Less common forms of dementia:

   --Pick's Disease: Pick's Disease affects personality, orientation and behavior. It may be more common in women and occurs at an early age.

   --Creutzfeldt-Jakob Disease: The disease progresses rapidly along with mental deterioration and involuntary movements.

   --Huntington's Disease: Huntington's is an inherited, degenerative disease. The disease causes involuntary movement and usually begins during mid-life.

   --Parkinson's Dementia: Parkinson's is a progressive disorder of the central nervous system. In later stages of Parkinson's disease, some patients develop dementia.

   --Lewy Body Disease: This disease causes symptoms similar to Alzheimer's disease. Individuals with Lewy Body Disease experience hallucinations and can become fearful.
