Hint Answer % Correct
what is Parkinson's disease characterised by? insidious onset, with slowing of voluntary movement, muscular rigidity, postural abnormality & tremors
100%
what are the 3 distinguishing features of Alzheimer's disease? accumulation of senile plaques (b-amyloid accumulations)
75%
formation of numerous neurofibrillary tangles
75%
what are examples of each? levodopa
75%
what are the drugs used to treat Alzheimer's disease? acetylcholinesterase inhibitors
63%
allosterically binding to GABAA receptors on post- synaptic neurons
63%
amantadine
63%
what is an example of a motor neuron disease? amyotrophic lateral sclerosis (ALS) etc
63%
carbidopa
63%
what is an example of each? donepezil, rivastigmine, etc
63%
what drugs do we use to treat Parkinson's? dopamine precursors
63%
dopamine receptor agonists
63%
loss of cortical neurons (especially cholinergic neurons)
63%
what are the physical effects of motor neuron disease? loss of motor neurons and muscle control until the patient can no longer eat, speak, move or breathe, with respiratory failure being the usual cause of death
63%
memantine
63%
what is the mechanism of action of each? metabolic precursor of dopamine, that is converted to dopamine by aromatic L-amino acid decarboxylase (AADC)
63%
what is Parkinson's disease caused by? the striatal deficiency of dopamine following neuronal degeneration within the substantia nigra
63%
benzatropine
50%
what are the mechanisms of action of the first drug thought to be? binding to glutamate receptors to reduce the release of glutamate
50%
inhibitors of dopamine metabolism
50%
NMDA receptor antagonists
50%
preferentially blocking TTX-sensitive sodium channels, which are linked to neuronal damage
50%
what are the drugs indicated specifically for motor neuron disease? riluzole, baclofen, edaravone, tizanidine
50%
uncompetitive antagonists at glutamatergic NMDA receptors
50%
what is motor neuron disease? a group of related neurodegenerative diseases that affect motor neurons and therefore voluntary muscle control
38%
antimuscarinic drugs
38%
bromocriptine, pramipexole, etc
38%
what is the mechanism of action of each? preferentially inhibits acetylcholinesterase (AchE) in the CNS over peripheral enzymes
38%
what does pharmacological treatment aim to do for Parkinson's? restore dopamine levels in basal ganglia
38%
inhibits AADC in peripheral tissues to increase availability of levodopa in the CNS by allowing more to cross the BBB before being converted to dopamine
25%
selectively blocks activity at the M1 muscarinic acetylcholine receptor, reducing cholinergic activity in the basal ganglia and restoring the ‘balance’ of acetylcholine and dopamine
25%
unknown, but thought to weakly inhibit the NMDA and nicotine receptors, as well as activate dopamine receptors
13%
agonists at dopamine D2 receptors, working to restore dopamine signalling in the striatum
0%
reduce the excitatory effect of acetylcholine
0%
