Parkinson's Flashcards
What is Parkinson’s?
-Brain disorder associated with a loss of dopamine-producing nerve cells
-less dopamine in the brain means less control over movement and less mobility
What is etiology of Parkinson’s?
-multifactorial
-both genetic and environmental factors
-age is the biggest risk factor
-median age of onset is 60years old
What are the cardinal symptoms of Parkinson’s?
-tremor
-rigidity
-bradykinesia
-postural instability
What are the non-motor symptoms of parkinson’s?
-anosmia
-REM
-sleep behavior disorder
-depression/anxiety
-fatigue
-pain
-confusion (sometimes dementia)
What are the characteristics of early stage parkinson’s?
-asymmetry of symptoms (initially unilateral presentation
-axial rigidity may be present (affecting proximal musculature)
-subtle changes in coordination and balance
-gait changes
-alteration in perception of movement (motor-sensory disconnect)
-organizational and dual-tasking ability changes
-mild cognitive impairment
What anatomy is affected?
-basal ganglia -> substantia nigra
*not producing enough dopamine
-basal ganglia circuitry
-involves basal ganglia and thalamus
-direct and indirect pathways
Which pathway is most dominant in parkinson’s? (direct or indirect)
indirect pathway
*facilitates basal ganglia output = less movement
*facilitation of an inhibitory pathway = inhibition
True or False: Parkinson’s starts proximally and asymmetrically.
True
What are some interventions used for Parkinson’s?
-weight shifts
-visual target that is past the freezing point
-metronome
-group interventions: tai chi, dance, kick boxing, BIG for life
-LSVT big and loud
-neuroplasticity principles
-PWR (similar is LSVT)
What neuroplasticity principles are most used with Parkinson’s interventions?
-Intensity
*keep it high
-Repetitions
*keep them high
*use it or lose it
*use it and improve it
-salience
*make it meaningful to their goals
-specificity
*try the things they are having trouble with
What are the H&Y stages?
1.0 unilateral involvement only
1.5 unilateral and axial involvement
2.0 bilateral involvement without impairment of balance
2.5 mild bilateral disease with recovery on pull test
3.0 mild to moderate bilateral disease; some postural instability; physically independent
4.0 sever disability; still able to walk or stand unassisted
5.0 wheelchair bound or bedridden unless aided
