warp Flashcards
what antidepressants cause migraine and headaches and collapse
MAOi - hypertensive criisis
is this happens crisis use alpha blocker to treat
can’t move eye down and medially can’t look at tip of nose and left eye is slightly deviated upwards , with double vision
CN4
trochlear nerve
suppose SO
depression of eyeball
right 3rd nerve palsy
right eye down and out
unable to adduct right eye
right 4th palsy
right eye turn up and out , right eye elevates too
benzodiapsxpeis work by inhaling GAAB complex
enhances cellular entry of CL-
hyper polarises the cell making it harder to simulate
inhibitory stimulus enhanced
long term side of l-dopa avoided by giving ropinirole
dyskinesia - involuntary movements
carbidopa - decarboxylase inhibitors monoamine oxidase b inhibitors e.g. rasagiline OCMT inhibitors - entacapone anticholinergics amantadine dopamine agonists
ropinirole stimulates the post synaptic dopamine receptors D2 in the CNS and PNS
what are some adverse reactions
n+v dyspepsia etc
direct pathway
cerebral cortex excites via glutamate striatum this then inhibits medial palladium this then inhibits the motor thymus inhbirtn the motor cortex
direct pathway what receptor
D1
indrifet pathway what receptor
D2
what protein is primary associate with neurofibrillary tangles
tau
what enzyme is responsible fro conversion of dopa to dopamine
DOPA decarboxylase
what is dopamine prescuor aa
tyrosine
most likely CN t risk of posterior communicating artery aneurysm
oculomotor nerve
runs close to this artery resulting in third nerve palsy
patient with MS suspect to peripheral nerve damage and no plaques found
what ytmpom would you most likely observe in patient
absent tenone reflex babinski hypetonic msucles muscle wasting paralysis of muscle groups
absent deep tendon reflexes
LMN
