Lewy body dementia is the progressive deterioration of mental abilities as a result of the abnormal accumulation of protein deposits called Lewy bodies in certain brain regions. This is second to Alzheimer’s disease as the most progressive kind of dementia. The symptoms include hallucinations, movement disorders which resemble Parkinson’s disease (shuffling walk, rigid muscles, and tremor), confusion, memory loss, poor attention, sleeping difficulties, depression, and apathy. This condition often affects elderly men more than women.
