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

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 Parkinson’s
disease. Parkinson's disease is a slowly
progressive neurological condition, characterized.by
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, olivopontocerebellar
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.
