Symptoms

By Mayo Clinic staff

Lewy body dementia signs and symptoms may include:

  • Visual hallucinations. Seeing colors, shapes, animals or people that aren't there may be one of the first symptoms of Lewy body dementia.
  • Movement disorders. Parkinson's-like signs may include slowed movement, rigid muscles, tremors or a shuffling walk.
  • Delusions. These may consist of false ideas about another person or situation.
  • Cognitive problems. Alzheimer's-like problems may include confusion, memory loss and a reduced attention span.
  • Sleep difficulties. A sleep disorder can cause you to physically act out your dreams while you're asleep.
  • Fluctuating attention. This may include frequent episodes of drowsiness, long periods of staring into space, lethargy or disorganized speech.
