LE 3: Evaluation of Patients with Involuntary Movements Flashcards
wedge-shaped mass of gray matter whose broad convex base is directly laterally and its blade medially
Lentiform Nucleus
a large c-shaped of gray matter closely r/t the lateral ventricle and lies to the thalamus
with a head, a body and a tail
caudate nucleus
it is related medially to the IC separating from the caudate nucleus and thalamus
Lentiform Nucleus
it is related laterally EC
Lentiform Nucleus
a thin sheet of white matter
EC
a thin sheet of gray matter
claustrum
_______ of white matter divides the nucleus into the putamen and GP
vertical plate
gives the basal ganglia control over emotions and other sexual functions
Limbic system
quick, lightning-fast mov’ts of face and upper ext.
TIC
Oscillatory, rythmic, regular mov’t affecting one or more body parts
Tremor
Involuntary, irregularity, purposeless, non-rythmic, abrupt, rapid, unsustained mov’ts that seem to flow from one body part to another
Chorea
Slow, writhing, continuous, involuntary mov’t
Athetosis
Very large amplitude choreic mov’ts of the proximal parts of the limbs causing flinging and flailing of limbs frequent and fast
Ballismus
twisting mov’ts that tend to be sustained at the peak of the mov’t, frequently repetitive and often progress to prolonged abnormal postures sustained mov’ts
Dystonia
Sudden, brief, shock-like involuntary mov’ts caused by muscular contractions
Myoclonus
due to inc. activity of indirect pw
ie. parkinson’s dse
Hypokinetic mov’t d/o
due to dec. activity of indirect pw
ie. huntington’s dse, choreoathetosis, hemiballismus, dystonia
hyperkinetic mov’t d/o
robot-like mov’t, very slow motion
Parkinson’s dse
bradykinesia, cogwheel type rigidity, shuffling gait, resting tremors(pill-rolling), stooped posture, hypomimia(masked facies), monotonous speech, dec. automatic mov’ts, micrographia, constipation, dementia, autonomic dysfxn, degen of dopaminergic neurons in SNr compacta
parkinson’s dse “paralysis agitans”
dec. in dopamine
Parkinson’s dse
dec. in GABA
Huntington’s dse
essential and senile chorea
Primary chorea
autosomal dominant, x’some 4, cognitive mov’t and psyche d/o
Huntington’s dse
some AD, others are AR, psyche disturbance, epilepsy, involuntary mov’ts, neuromuscular weakness
Neuroacanthocytosis
