Dementia with Lewy bodies

Dementia with Lewy bodies is similar to Alzheimer's disease in that it is caused by the degeneration and death of nerve cells in the brain. It takes its name from the abnormal collections of protein, known as Lewy bodies, which occur in the nerve cells of the brain.

Half or more of people with Lewy body disease also develop signs and symptoms of Parkinson's disease. People with Lewy body disease are very sensitive to some tranquillisers known as antipsychotic or neuroleptic drugs and their use should be avoided if at all possible.

Dementia with Lewy body affects:

  • Concentration and attention
  • Memory
  • Language
  • The ability to judge distances
  • The ability to reason
  • People with Lewy body disease can experience visual hallucinations
