Hypokinesia and Hyperkinesia Flashcards
where is degeneration seen with Huntington’s?
striatum and cerebral cortex
what can an OT do for Tourette’s?
stress management
what structure does the GPi act on?
thalamus
involuntary, jerky, rapid movements
chorea
with Parkinson’s, an excessively inhibited thalamus leads to what?
excessive inhibition of descending motor tracts by M1
when the putamen lacks dopamine, what can it not adequately regulate? (Parkinson’s)
globus pallidus internus
which disorders involve an abnormal accumulation of protein deposits in neurons?
progressive supranuclear palsy and dementia with Lewy bodies
what are examples of hypokinetic disorders?
Parkinson’s, Parkinson’s plus, Parkinsonism
what can an OT do for multiple system atrophy?
fall prevention, address postural hypotension, exercise program
what can an OT do for freezing of gait?
auditory cueing, visual targets
these symptoms indicate what disorder?: Early onset of gait instability (tendency to fall backward), Supranuclear gaze palsy, Unable to control gaze (vertical gaze affected first), Affects UMNs that synapse with cranial nerve nuclei in brainstem controlling eye movement, Rigidity, Freezing of gait, Depression, Psychosis, Rage attacks
progressive supranuclear palsy
type of dystonia: most common, limited to one part of body
focal dystonia
Spontaneous (sometimes uncontrollable) activities resulting from a lesion. Words such as “new”, “spontaneous” may be used (e.g., tremors, tics)
positive sign
Excessive inhibition of motor structures by the BG; negative signs
hypokinetic disorders
when the GPi isn’t adequately regulated by the putamen, what does it do? (Parkinson’s)
excessively inhibits motor structures
what can an OT do for dementia with Lewy bodies?
establish routines, eliminate distractions, provide familiar environment
side effect of drugs that treat psychosis or digestive problems (usually dopamine blockers)
drug-induced Parkinsonism
what can an OT do for Huntington’s?
adaptive equipment, environmental modification, alter routines
