What are the other common types of Dementia?
Parkinson’s disease is seen in 4-8% of people with dementia and may be an additional disorder in other dementias like Alzheimer’s and Multi Infarct Dementias. Movement symptoms include resting tremor, progressive slowness of movement, limb and trunk rigidity, impaired posture and balance, poor coordination, and gait and swallowing problems. In late stages, walking, talking, and doing simple tasks often becomes severely impaired. Depression, sleep disturbance, and excessive sweating are also common. In the later stages, dementia may be seen. Parkinson’s may develop over 20 years or may progress more rapidly. Lewy Body Dementia is rather like Parkinson’s disease in reverse. Both diseases have Lewy Bodies seen in the motor neurons but Lewy Body Dementia presents with an initial dementia with the parkinsonian movement disorder coming later in the progression of the disease—just the opposite of Parkinson’s disease. Lewy Body Dementia is virtually indistinguishable from Alzheimer’s disease
