module menu icon Dementia with Lewy bodies

Lewy bodies are tiny protein deposits (alpha-synuclein) that appear in nerve cells in the brain. Lewy bodies are the cause of dementia with Lewy bodies (DLB) and the symptoms of DLB will depend on which part of the brain the Lewy bodies are in. They disrupt the way the brain functions, reducing levels of chemical messengers and causing cells to die. People with DLB may: 

  • Have problems with attention and alertness, which may vary during the day 
  • Struggle judging distances and seeing objects in three dimensions 
  • Have problems with planning, organising and decision making 
  • Experience depression 
  • Have visual hallucinations, which often occur in the early stages of DLB 
  • Experience auditory hallucinations 
  • Have memory problems.
