Parkinsonian Dementia

Diagnosis & Treatment

Cognitive impairment is a common feature of movement disorders such as Parkinson’s Disease (PD), Progressive Supranuclear Palsy (PSP), Multiple System Atrophy (MSA), Corticobasal Syndrome (CBS) and Huntington’s disease (HD).


People with PD dementia (PDD) may experience changes in memory, concentration and judgment; trouble interpreting visual information; visual hallucinations; delusions, especially paranoid ideas; depression, irritability and anxiety; and sleep disturbances, including excessive daytime drowsiness and rapid eye movement (REM) sleep disorder. Memory problems can occur even at the early stage of PD greatly affecting the quality of life. Similar cognitive impairment occurs in atypical Parkinsonism such as PSP, MSA and CBS. HD also causes a decline in thinking and reasoning skills, including memory, concentration, judgment and ability to plan and organize.
