Mehl. bullet Epilepsy + drugs epilepsy/hypnotics Flashcards
M. 56M + 3-day Hx of cutting from 12 beers a day down to 4; develops tremulousness; Tx?
chlordiazepoxide (delirium tremens);
M. classic vignette is guy has surgery + two days later has tachycardia, tremulousness, and hallucinations, Dx?
alcoholic hallucinosis
M. 6M + ECG shows miscellaneous arrhythmia + seizure-like episode; Dx?
Adam-Stokes attack –> not true seizure disorder as per EEG; arrythmia leads to hypoxia of brainstem –> seizure-like fits ensue.
M. 75M + episodes of loss of consciousness (LoC) for 2 years + tonic-clonic-like episodes + becomes pale
and sweaty + Hx of MI; Dx?
answer = “syncope” on the NBME (convulsive syncope).
M. What is simple vs complex seizure?
simple = no LoC;
complex = LoC;
patient staring off into space not aware of surroundings = LoC.
M. What is partial vs generalized seizure?
partial = affecting one part of the brain;
generalized =
involves the wholes of both cerebral hemispheres.
M. What is myoclonic seizure?
jerks in muscle or group of muscles; no LoC.
M. 13M + tonic-clonic seizure + 4-month Hx of hypnagogic/hypnopompic jerking of left arm + uncle has epilepsy; Dx?
juvenile myoclonic epilepsy; genetic with unclear inheritance pattern; characterized by myoclonic jerks (usually hypnagogic and/or hypnopompic) that progress to tonic- clonic seizures after several months; age of onset is usually 10-16, but can also start in adulthood;
M. 13M + tonic-clonic seizure + 4-month Hx of hypnagogic/hypnopompic jerking of left arm + uncle has epilepsy; Tx?
Dx = juvenile myoclonic epilepsy;
Tx = valproic acid
M. 4F + few-month Hx of near-daily seizures + seizures typically occur while she’s sleeping + has started putting objects in her mouth and making less eye contact + seizures not responding to anti-epileptic meds; Dx?
Lennox-Gastaut syndrome
severe childhood-onset epilepsy characterized by near-daily seizures and cognitive decline (hyperoralism is a sign of cognitive regression [babies put things in their mouths]); poor prognosis, with 5% mortality rate in childhood; 80-90% persistence of seizures into adulthood.
M. 10-month old boy + jerking movements of the limbs + EEG shows chaotic high-amplitude spikes with no recognizable pattern; Dx?
West syndrome (infantile spasms)
triad of spasms + hypsarrhythmia on EEG (no recognizable pattern with high amplitude spikes) + developmental regression; international definition of the diagnosis requires two out of three; starts age 3-12 months; seen in 1-5% of Down syndrome kids;
M. 10-month old boy + jerking movements of the limbs + EEG shows chaotic high-amplitude spikes with no recognizable pattern; Tx?
Dx = West syndrome (infantile spasms)
Tx = Tx = ACTH, prednisolone, or vigabatrin; ACTH is thought to act by two mechanisms: 1) stimulates steroid (cortisol) release; 2) direct (cortisol-independent) effect on melanocortin receptors.
M. 32M + fear of flying; Dx + Tx?
specific phobia; Tx with benzo.
M. 32M + fear of public speaking (glossophobia); Dx + Tx?
social phobia, not specific phobia; Tx =
atenolol (propranolol also OK).
25F + fear of flying + must fly soon; Tx?
Lorazepam -> specific phobia.
M. 27M + asthma + very anxious about speech he needs to make soon; Tx?
Psych NBME wants lorazepam, not propranolol (because asthma patient).
M. 27M + very anxious about speech he needs to make soon; Tx?
Psych NBME wants propranolol, not lorazepam. (because no asthma - safe give BAB)
