NINJA - PRITE review questions
What characterizes the memory loss in patients with dissociative amnesia? (x2) - ANS Episodic
Amnesia preceded by epigastric sensation/fear are associated with electrical abnormalities
where? - ANS Temporal lobe
Memory loss pattern in dissociative amnesia? - ANS Occurs for a discrete period of time
(episodic!)
Amnesia characterized by loss of memory of events, occur after onset of etiologic condition or
agent? - ANS Anterograde
What psychoactive drug produces amnesia? - ANS EtOH
Pt with strange behavior answers appropriately with fluent speech but no ability to retain new
information. Episode lasts 6 hours then back to normal. No recollection of events. What is the
diagnosis? - ANS Transient global amnesia
Pt reports hearing voices of someone not present, stops moving, stares blankly, repetitively
picks at clothing, does not respond to questions/commands for several minutes. The confusion
resolves after 15 minutes but pt has no recollection of events. Likely what? - ANS Complex
partial seizure
55 y/o pt BiB family after episode of amnesia/bewilderment lasting several hours. CVA ruled out.
Pt keeps asking what is happening. What medication to administer at this point? - ANS
Observation with no pharmacological intervention
Which of the following diagnoses involves a sense of loss of identity, often following a traumatic
experience and associated with inability to recall one's past? - ANS Dissociative fugue
Contralateral leg weakness with sparing of the face and arms. Urinary incontinence and abulia.
Where is the lesion? - ANS Anterior cerebral artery
Visual problem in pituitary tumor compressing optic chiasm (x10)? - ANS Bitemporal
hemianopsia
60 y/o right handed M, getting lost, only writes on right half of paper. Left-sided hemi-neglect.
Where is the lesion? (x8) - ANS Right parietal lobe
66 yo c/o frequent falls, several month h/o of anxiety, unwillingness to leave home. On exam,
mild impairment of vertical gaze on smooth pursuit, saccades, mild axial rigidity of upper
, extremities, along with mild slowness of movement on finger tapping, hand opening and wrist
opposition. Posture normal. Gait tentative/awkward, but w/o shuffling, ataxia, tremor. Pt is slow
in arising from chair. Most likely diagnosis? 5x - ANS Progressive supranuclear palsy
65 yo pt fell several times in past 6 months. MSE normal. Smoth pursuit, saccadic movements
impaired. Worse with vertical gaze. Full ROM with doll head maneuver. Mild symmetric
rigidity/bradykinesia, no tremor. MRI/CSF/labs unremarkable. Diagnosis? x4 - ANS Progressive
supranuclear palsyof right hand for
26 y/o with headache, clumsiness of right hand for weeks. Struggles with rapid alternating
movements of right hand, overt intention tremor with finger to nose, mildly dysmetric finger
tapping. CNS normal, no papilledema. Damage to what is seen on MRI? x3 - ANS Cerebellum
9 y/o F has 3 month h/o seemingly unprovoked bouts of laughter. Worse when not sleeping well.
Pt does not feel happy during these episodes. Started menstruating 6 months ago and at
Tanner stage 4. Diagnosis? x2 - ANS Hypothalamic hamartoma
5 y/o with 4 month history of morning headache, vomitting, and recent problems with gait, falls,
and diplopia. Diagnosis? x2 - ANS Medulloblastoma
75 yo patient evaluated for progressive gait urine incontinence and cognitive decline. After
removal of csf, there is improvement in gait and balance. What would CT show? - ANS
Enlargement of frontal horns
70 yo pt develops confusion, lethargy, and generalized tonic clonic seizures. Lab reveals serum
sodium of 95 meq/L. This is most likely a complication of excessively rapid correction of which
metabolic problem? - ANS Central pontine myelinolysis
Which lesion causes b/l coarse nystagmus worsening with visual fixation and present with
horizontal and vertical gaze? - ANS Brain stem
32 y/o pt 1 month history of worsening headaches, episodic mood swings and occasional
hallucinations with visual, tactile and auditory content. CT head reveals tumor where? - ANS
Temporal lobe
Syndrome characterized by fluent speech, preserved comprehension, inability to repeal, with
associated signs. Location of lesion in the brain? - ANS Supramarginal gyrus or insula
Acute onset of hemiballismus of LUE and LLE MRI is most likely to show lesion located where?
- ANS Subthalamic nucleus
43 y/o newly diagnosed AIDS pt has increasing social withdrawal and irritability over several
weeks. Can't remember phone number, unable to do chores, appears distracted. Mild right
