What is Lewy Body Dementia?

Lewy Body Dementia is a progressive dementia that leads to a decline in thinking, reasoning and independent function due to abnormal microscopic protein deposits in the brain that damage cells over time. Many experts estimate that Lewy Body Dementia is the third most common form of dementia after Alzheimer's disease and vascular dementia.

Lewy Body Dementia is named after neurologist, Frederich H. Lewy, M.D. who discovered these microscopic Alpha-synuclein protein deposits (aka Lewy bodies) while working in Dr. Alois Alzheimer's laboratory during the early 1900s.

What are the most common symptoms?

  • Changes in thinking and reasoning
  • Hunched posture, balance problems and rigid muscles
  • Visual hallucinations and/or delusions
  • Trouble interpreting visual information
  • Confusion that may vary in severity from one day to the next
  • Memory loss but not as severe as in Alzheimer’s disease

How is it diagnosed?

There is no single test that can conclusively diagnose Lewy Body Dementia. Instead, a physician makes a clinical determination based on the onset, variety and severity of symptoms
