1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11

Question # 1 (Multiple Choice) Reason that dopamine itself is not used to treat in Parkinson's disease:

Answer: (C) dopamine does not cross the blood-brain barrier

BACK

Question # 2 (Multiple Choice) Dominantly inherited disease: associated with progressive chorea and dementia; related to neurotransmitter imbalance

Answer: (D) Huntington's disease

BACK

Question # 3 (Multiple Choice) Antiviral drug found to have anti-Parkinson's properties:

Answer: (C) amantadine

Anti-Parkinson mechanism of action unclear; knack by affecting dopamine reuptake, synthesis, or release BACK

Question # 4 (True/False) Benefits of dopaminergicanti--Parkinson's drugs probably due to stimulation of D2 dopamine receptors

Answer: True

BACK

Question # 5 (Multiple Choice) Irregular, unpredictable, involuntary muscle contractions:

Answer: (D) chorea

chorea: may be hereditary, secondary to non--neurological disease; drug-induced BACK

Question # 6 (Multiple Choice) Dopamine agonist ergot derivative -- stimulates D1 & D2 receptors

Answer: (C) pergolide

pergolide & bromocriptine are ergot alkaloid derivatives useful in treating Parkinson's disease BACK

Question # 7 (Multiple Choice) Characterized by chronic, multiple tics:

Answer: (D) Tourette's syndrome

BACK

Question # 8 (Multiple Choice) Percentage of levodopa that enters the brain unaltered

Answer: (A) 1-3%

most levodopa is metabolized extracerebrally BACK

Question # 9 (Multiple Answer) Effective in managing essential tremor

(A) propranolol

(B) metoprolol

(C) primidone

probably a beta-adrenergic receptor dysfunction; anti-Parkinson agents, diazepam, chlordiazepoxide, mephenesin not useful BACK

Question # 10 (Multiple Choice) First-line anti-Parkinson drug; also used to treat hyperprolactinemia at lower doses

Answer: (C) bromocriptine

ergot derivative; dopamine agonist, probably at D2 receptors BACK
