Aside from asymmetrical PD s/s, the signs & symptoms unique to CBD are visuospatial impairments, apraxia, and ____ (2)
myoclonus and progressive aphasia
24
T/F: There is currently no cure available for CBD and treatment is largely supportive (symptom based)
True.
25
CBD prognosis indicates an average survival of ____ years from symptom onset.
6-8 but there are cases of people surviving >10 years.
26
_____is not a "Parkinsonism" but a BG diagnosis characterized by involuntary muscle contractions >slow, repetitive movements/ abnormal postures
dystonia
27
the 5 classifications of dystonia are:
focal-1 body part segmental (2+ continuous body parts) multifocal (2+ noncontinuous parts) generalized (trunk and 2+body parts) hemi
28
Dystonia is typically onset at childhood and early adulthood and the difference in presentation is that early onset presents w/ ____while adult onset presents with ____
limb involvement; neck/facial involvement
29
Dystonia is typically ____but can also be genetic or acquired and there aren't any identifiable damages on imaging.
idiopathic
30
what are the 4 common initial s/s of dystonia? (hint: 3 in foot, 1 in hand). Generally speaking these may lead to contracture.
foot: cramping, toe drag, and/or excessive inversion @ swing hand: cramping while writing
31
what are the effects of eyelid and neck/trunk dystonias?
eyelid: excessive blinking neck/trunk: postural abnormality
32
T/F: Dystonia can be circumstantial and only impact specific movements.
true
33
What are the 4 pharmacologic treatment options for dystonia and which have the highest success rate?
**Botox** but also anticholinergics, GABAergic and dopaminergic agents have mixed reviews.
34
___,___, ____,and____ are surgical intervention options for dystonia that aren't usually a go-to due to invasiveness. Of them___is the most common.
Deep Brain stimulation, thalamotomy, pallidotomy, and anterior cervical rhizotomy DBS
35
_____has no direct mortality prognosis or commonly fatal secondary complications
Dystonia
36
_____is a drug induced dx that involves uncontrolled stiff and jerky movements of the face/body. The primary culprits are____ and ______
tardive dyskinesia; amphetamine/meth/haloperidol and phenothiazines (for schizophrenia)
37
risk factors for TD are the amount/long term use of the drug, drug. abuse, and __(3 demographic RFs)
age >55, women>men, race (Black and Asian)
38
TD is dx via clinical exam and med review. Its treated via Deutetrabenzine, Valbenzine or ____
Cessation!
39

Dominant hyper-
40
The pathophysiology of Huntington's involves severe loss of neurons in the ___ and putamen, among other lobes, that resembles ______on imaging.
caudate, dilation of lateral ventricles
41
In HD, the indirect "no-go" pathway is hit first causing ______. Next, the direct "go" pathway is hit and we see more widespread loss and s/s similar to ____
disinhibition of thalamus (runnin amuck) PD
42
HD is characterized by unique s/s including mood changes, cognitive impairment (including dementia and OCD) , and ____(3)

How is the prognosis for Huntington's?
