Lewy body dementia signs and symptoms may include:

  • Visual hallucinations. You may see visual hallucinations, such as colors, shapes, animals or people that aren't there. Hallucinations may be one of the first symptoms of Lewy body dementia. Some people also may experience sound (auditory), smell (olfactory) or touch (tactile) hallucinations.
  • Movement disorders. You may experience symptoms similar to those of Parkinson's disease (parkinsonian symptoms), such as slowed movement, rigid muscles, tremors or a shuffling walk.
  • Poor regulations of body function. Blood pressure, pulse, sweating and digestive process are regulated by a part of the nervous system that is often affected by Lewy body dementia. This can result in dizziness, falls and bowel issues.
  • Cognitive problems. You may experience thinking (cognitive) problems similar to problems experienced in Alzheimer's disease, such as confusion, reduced attention span and eventually memory loss.
  • Sleep difficulties. You may have a sleep disorder called rapid eye movement (REM) sleep behavior disorder that can cause you to physically act out your dreams while you're asleep.
  • Fluctuating attention. You may have frequent episodes of drowsiness, long periods of staring into space, long naps during the day or disorganized speech.
  • Depression. You may experience depression sometime during the course of your illness.
