25
Drug induced parkinsonism can also result from some ______ medications
neuroleptic
26
Cigarette smoking may (decrease/increase) the risk of PD
decrease --> possibly because carbon monoxide is a free radical scavenger
27
Confirmation of PD is only via ___.
autopsy
28
What criteria should you follow for clinical diagnosis of PD?
1. clinically possible if the patient has a resting tremor, asymmetric rigidity, or asymmetric bradykinesia; 2. clinically probable if the patient has any 2 of the above symptoms; and 3. definite if, in addition, there is a definitive response to anti-parkinsonian drugs.
29
PD has long been associated with loss of _______ cells in the substantia nigra of the midbrain.... however, the site of action of this neurotransmitter loss is in the basal ganglia
dopamine-producing
30
Dopamine is normally transmitted by way of nigrostriatal neurons from the brainstem to the ____
basal ganglia
31
Current theory of PD is that the progressive loss of nigrostriatal neurons is accompanied by an increase in ____ cells in the substantia nigra and a loss of ____.
increased glial cells; loss of neuromelanin
32
What in non-motor areas may account for the non-motor symptoms associated with PD?
Lewy bodies of surviving nigrostriatal neurons
33
(true/false) All pharmacological agents used to treat people with PD ***ARE NOT*** associated with significant side effects
FALSE (they are) gastrointestinal (eg, nausea, vomiting, constipation) CNS (eg, confusion, delirium, hallucinations, behavioral changes) neurologic (eg, dyskinesias, dystonias) cardiovascular (eg, orthostatic hypotension, dysrhythmias)
34
Motor symptoms become too disabling if patient is in the (on/off) state for too long during the day
off state
35
Current surgical methods rely on ______ of deep brain structures
e-stim
36
The sites for deep brain stimulation (DBS) include the _____ or ____.
globus pallidus or subthalamic nuclei
37
Modified H & Y scale stage ___: no signs of disease
0
38
modified H & Y scale stage ___: unilateral disease
1
39
Modified H & Y scale stage ___: unilateral plus axial involvement
1.5
40
Modified H & Y scale stage ___: bilateral disease without impairment of balance
2
41
Modified H & Y scale stage ___: mild bilateral disease; recovery on the pull test
2.5
42
Modified H & Y scale stage ___: mild-moderate bilateral disease, some postural instability; physically independent
3
43
Modified H & Y scale stage ___: severe disability but able to walk or stand unassisted
4
44
Modified H & Y scale stage ___: WC bound or bedridden unless receiving aid from someone
5
45
Those who undergo DBS can only improve to their best (on/off) state condition prior to the DBS
on state
46
What surgical management intervention addresses the symptoms of the disease but does not affect the progression of the disease?

3
52
Original H & Y scale stage ___: severely incapacitating disease but ale to walk and stand independently
4
53
Original H & Y scale stage ___: confined to bed and WC unless receiving assistance
5
54
Compared to shorter format LSVT-BIG or general exercise, LSVT-BIG was (less/more) effective at improving motor function.
