OA Parkinson's Flashcards
Parkinson’s Disease
- neurodegenerative disease
- largely unknown cause
- no diagnostic test
- no prevention, no cure
- debilitating
- progressive with complications
Parkinson’s increases with…
age
age of onset for Parkinson’s
50s-60s
peak onset for Parkinson’s
70s
What gender is Parkinson’s more common?
men
What type of degeneration results in Parkinson’s?
-degeneration of dopamine-producing neurons in substantia nigra of the midbrain
What does the degeneration of dopamine producing neurons in the midbrain disrupt?
it disrupts dopamine-acetylcholine balance in basal ganglia
The increase of acetylcholine results in…
clinical manifestations
Motor clinical manifestations of Parkinson’s
- bradykinesia
- rigidity
- resting tremors
- impaired postural reflexes
**at least 2 of 4 for diagnosis
bradykinesia
slowing of initiation and execution of movement
rigidity due to…
- increased muscle tone
- involuntary muscle contractions
resting tremors
- HANDS, arms, legs, jaw, face
- “pill-rolling”
what type of impaired postural reflexes are typical for Parkinson’s
late response
Non-motor clinical manifestations
- cognitive changes
- sleep abnormalities
- emotional changes
Stages of Progression
- PD symptoms affect only one side of body
- symptoms both sides, balance intact
- mild to moderate symptoms, balance impaired, still functions independently
- severely disabled, but can still walk or stand without assistance
- wheelchair-bound or bedridden
The “classic” Parkinson’s Patient
- stooped posture
- masked faces
- drooling
- shuffling gait
- “frozen” in place
- difficulty controlling posture
Complications that result from Parkinson’s
- dysphagia
- urinary incontinence
- lack of mobility
- orthostatic hypotension
- depression
- dementia
