What is Lewy Body Dementia?

Lewy body dementia (LBD) disease is associated with abnormal deposits of a protein called alpha-synuclein in the brain. These deposits, called Lewy bodies, affect chemicals in the brain whose changes, in turn, can lead to problems with thinking, movement, behavior, and mood, stated the National Institute of Aging. According to National Institute of Neurological Disorder and Stroke, more than one million Americans suffer from this condition.

The condition is usually mistakenly identified as Alzheimer's disease or Parkinson'. This leads to misdiagnoses in patients who are actually suffering from Lewy body dementia. Media magnet Ted Turner was in fact misdiagnosed with bipolar disorder, whereas robin Williams was misdiagnosed with Parkinson's disease.

Robin William's wife Susan Schneider Williams had called the condition "the terrorist inside my husband's brain." Lewy body dementia affects people in seven stages. It starts with no cognitive decline then develops into mild cognitive decline in stages two and three, then it intensifies to moderate cognitive decline in stage four and develops into moderately severe cognitive decline in stage 5. When it reaches stage six the condition is identified as severe cognitive decline that develops into very severe cognitive decline in stage seven.
