Symptoms of Lewy body disease

Symptoms of Lewy body disease

People with Lewy body disease have cognitive problems (problems with thinking, memory, language, etc.) similar to those that occur in Alzheimer's disease. Therefore, it can be hard to distinguish the two. Some doctors think there are three distinguishing features and the presence of two of them makes the diagnosis of Lewy body disease probable:
  • Motor problems typical of Parkinson's disease but usually not so severe as to warrant a diagnosis of Parkinson's. Of these problems, an impairment in walking (a shuffling gait) might be the most common one. Also common would be muscle stiffness and a tendency to fall. Tremor would be less common.
  • Fluctuations in cognitive function with varying levels of alertness and attention. Periods of being alert and coherent alternate with periods of being confused and unresponsive to questions.
  • Visual hallucinations, usually occurring early on. Delusions may be common too.
It's possible that people with Lewy body disease are better able to form new memories than those with Alzheimer's disease. Compared with Alzheimer's, Lewy body disease may affect speed of thinking, attention and concentration, and visual-spatial abilities more severely than memory and language. Depression may be a typical symptom too.
