Parkinsons Flashcards
Athetosis Chorea Hemiballius lesions
A= (GAP) — GLOBUS PALLIDUS
C= CAUDATE NUCLEUS
Hb (Always U/L) = STN C/L**
Chorea causes
CHOREA
Chorea gravidarum
Huntingtons
OCP***
Rheumatoid—Sydenhams
Endocrine—Thyrotoxicosis
Mcc= SLE***
Atherosclerotic—Senile
MC neuro degenerative do
ALZHEIMER»PD
Pathology PD
Atrophy + Hypopigmentation of SNPC
Lewy Body deposition (a-synuclein)
Nigrostriatal pathway impairment
(STRIATUM= Putamen + CN)
D1 and D2 receptors function
D1= Stimulate stimulatory
D2 = Stimulate inhibitory

Behaviour (Depression)
Movement regulation (EPS)
EPS list
NAAT

Akathisia
Acute Muscle Dystonia
TD
Etiology PD
DTTGSE
Drugs (Antags and Depletors)
Toxins ( Hexane/ CO / Mn / Methanol)
Trauma (Alzheimer»PD)
Genetic (Parkin «_space;LRRK)—5%
Sporadic (mc)
Enzyme deficiency (Ty Hydroxylase— Rate limiting in DA formation)
DA depletors
Methyl dopa Reserpine Tetrabenzene Lithium Amiodarone
DA antags

Parkin LRRK features
P= AR—Early onset—Chr12
L= AD—>40y—Chr 6
Cf Pd
TRAP
Tremors (Resting/4-6Hz/ UL>LL / Unilat / dec with sleep)
Rigidity (Cogwheel-UL / leadpipe-LL)
Akinesia
Postural instability (Akathisia)
(LEAD PIPE rigidity is usually seen in EPS but tremors + LPR= cogwheel rigidity)
Gait in PD
Festinating/ Shuffling
KINESIA PARADOXA***
Increased acceleration while running
