Dementia Due to Parkinson's Disease Symptoms and DSM-IV Diagnosis

Dementia Due to Parkinson's Disease Symptoms and Diagnosis Overview:

Dementia Due to Parkinson's Disease symptoms and diagnostic criteria follow below. While some of these Dementia Due to Parkinson's Disease symptoms may be recognized by family, teachers, legal and medical professionals,  and others, only  properly trained mental health professionals (psychologists, psychiatrists, professional counselors etc.) can or should even attempt to make a mental health diagnosis. Many additional factors are considered in addition to the Dementia Due to Parkinson's Disease symptoms in making proper diagnosis, including frequently medical and psychological testing considerations. This information on Dementia Due to Parkinson's Disease symptoms and diagnostic criteria are for information purposes only and should never replace the judgment and comprehensive assessment of a trained mental health clinician. 


294.1 Dementia Due to Parkinson's Disease 

The essential feature of Dementia Due to Parkinson's Disease is the presence of dementia that is judged to be the direct pathophysiological consequence of Parkinsonís disease. Parkinson's disease is a slowly progressive neurological condition, tremor, rigidity, bradykinesia, and postural instability. Dementia has been reported to occur in approximately 20%-60% of individuals with Parkinson's disease and is more likely to be present in older individuals or those with more severe or advanced disease. The dementia associated with Parkinson's disease is characterized by cognitive and motoric slowing, executive dysfunction, and impairment in memory retrieval. Declining cognitive performance in individuals with Parkinson's disease is frequently exacerbated by depression. Findings on physical examination include the characteristic abnormal motor signs of resting tremor, evidence of slowness and poverty of movement (such as micrographia), or muscular rigidity and loss of associated movements. At autopsy, neuronal loss and Lewy bodies are evident in the substantia nigra. There are a number of syndromes that may manifest with dementia, parkinsonian movement disorders, and additional neurological features (e.g., progressive supranuclear palsy, olivoponto≠cerebellar degeneration, and Vascular Dementia). Some individuals with Parkinson's disease and dementia are found at autopsy to have coexisting neuropathology indicative of Alzheimer's disease or of diffuse Lewy body disease.
