Aberrant eating behavior in elderly parkinsonian patients with and without dementia : analysis of video-recorded meals

• Aberrant eating behavior among 14 elderly, non-demented and 10 demented patients with Parkinson's disease was studied by means of video-recordings. The findings revealed problems in handling food on the plate, transporting food into the mouth, manipulating food in the mouth, and swallowing. Interpretations were performed based on impairments of autonomic processes, perception, cognition, emotion, and motor performance that occur in the disease.
