Parkinson’s disease dementia
Parkinson’s disease is a chronic, progressive neurological condition. Its symptoms include tremors, rigidity, akinsesia (immobility) and postural instability, muscle stiffness and reduced muscular power. Most people with Parkinson’s disease will develop dementia. Reasoning, memory, speech, and judgment are usually affected. Parkinson’s is also often accompanied by depression, hallucinations, and anxiety.
Visuo-spatial functions such as orientation, perception and construction may be particularly affected, causing a concern about driving. Memory may be affected in recall of recent events or learning new material, although memory usually improves with cueing. Language is usually preserved although word finding difficulties and impaired comprehension of complex sentences may be present.
