Lewy Body Dementia
Signs and Symptoms

Symptoms of Lewy body dementia include:

  • Progressive cognitive decline, memory loss and confusion
  • Fluctuating ability to comprehend and focus attention
  • Recurring visual hallucinations that are typically detailed
  • Symptoms similar to Parkinson's disease such as stiff muscles and shuffling gait.

Unlike Alzheimer’s disease, which tends to progress gradually, this disease often starts rapidly, with a fast decline in the first few months. Later, there may be some leveling off but Lewy body dementia typically progresses faster than Alzheimer's. A patient can survive from five to seven years with the disease.
