Lewy Body

"Lewy body disease is one of the most common causes of Dementia in the elderly. Lewy body disease happens when abnormal structures, called Lewy bodies, build up in areas of the brain. The disease may cause a wide range of symptoms, including: changes in alertness and attention, hallucinations, problems with movement and posture, muscle stiffness, and confusion.

 

Lewy body disease can be hard to diagnose, because Parkinson's disease and Alzheimer's disease cause similar symptoms. Scientists think that Lewy body disease might be related to these diseases, or that they sometimes happen together.

 

Lewy body disease usually begins between the ages of 50 and 85. The disease gets worse over time. There is no cure. Treatment focuses on drugs to help symptoms."

"Who was Lewy? In the early 1900s, while researching Parkinson's disease, the scientist Friederich H. Lewy discovered abnormal protein deposits that disrupt the brain's normal functioning. These Lewy body proteins are found in an area of the brain stem where they deplete the neurotransmitter dopamine, causing Parkinsonian symptoms.

 

In Lewy Body Dementia [LBD], these abnormal proteins are diffuse throughout other areas of the brain, including the cerebral cortex. The brain chemical acetylcholine is depleted, causing disruption of perception, thinking and behavior. Lewy body disease exists either in pure form, or in conjunction with other brain changes, including those typically seen in Alzheimer's disease and Parkinson's disease."
