Stroke vs Malingering • Rianna Leigh R. Salazar, MD
Objective • Discuss ways to differentiate a true neurologic deficit from a patient who is malingering
30 minutes prior While on ROTC Training Loss of consciousness Case of JIO On the way to TMC-ER Left-sided weakness Left sided weakness Chief Complaint • 18 year old • Female • College student • from Bicol *RIGHT HANDED
Past Medical History • Syncope (2011-NYC), less than 10 minutes • ECG - normal, sent home with no medications • Occasional palpitations since childhood • no consult • Acid peptic disease • Omeprazole • Headaches since 4 years ago • Paracetamol given, last headache last month

Physical Examination • General: Alert, awake, not in cardiorespiratory distress • Vital Signs: • BP 90/60 HR 54 RR 19 T 37.0°C • Pain scale 7/10 • Essentially normal HEENT, Pulmonary, Cardiovascular, Abdominal, Extremities examination
Physical Examination • Alert, conversant, oriented to 3 spheres, GCS 15 • Cranial Nerves: • I: not assessed • II: pupils 2-3mm EBRTL • III, IV, VI: full range EOM • V1: 60% sensory, Left • V2: 50% sensory, Left • V3: 50% sensory, Left • VII: shallow NLF, Right • VIII: intact gross hearing • IX, X: intact gag and swallowing • XI: moves head left and right, shrugs both shoulders • XII: tongue midline
Physical Examination • DTR: • 2+ all extremities • Motor: • 5/5 right upper and lower extremities • 0/5 left upper and lower extremities • Sensory • 100% right upper and lower extremities • 0% left upper and lower extremities • Cerebellar: intact FTNT, right • Supple neck • Babinski: negative • Negative for clonus
Admitting Impression • Stroke in the young vs Reversible Ischemic Neurologic Deficit
Differential Diagnosis • Migraine • Seizure • Infection • Demyelination • Hypoglycemia family history? undiagnosed case? history of headache loss of consciousness tonic clonic? postictal? headache no fever, work-up? sensori-motor deficits constitutional signs? headache, ROTC last meal? CBG?
At the ER • Admitted under IM, BAT was called • Laboratory tests were normal: CBC, CK Enzymes, PT, aPTT, Na, K, iCal, Mg, SGPT, Total Cholesterol, HDL, LDL, Triglycerides, VLDL, RBS, BUN, Creatinine, ABGs, urinalysis • Cranial MRI: normal • ECG: normal sinus rhythm • Citicholine 500mg IV every 12 hours (adult dose) as neuroprotective • Aspirin 80mg tablet once a day as antiplatelet
Working Impression • Stroke in the young vs Reversible Ischemic Neurologic Deficit vs Malingering
PATIENT WAS ABLE TO DO THIS WITH NO SUSPICION OF NONORGANIC CAUSE Greer, S, Chambliss, L and Mackler L, What physical exam techniques are useful to detect malingering? The Journal of Family Medicine 2005: 719-722
At the PICU (1st hospital day) • 2D echo: normal • Improving neurologic status • Vital signs are stable • Cranial Nerves: • V1: 60% -> 70% • V2: 50% -> 60% • V3: 50% -> 60% • Motor: • 5/5 right upper and lower extremities • 2/5 left upper and lower extremities • Sensory • 100% right upper and lower extremities • 25% left upper and lower extremities • DAMA
Stroke in the young vs Malingering • Discharge Diagnosis
Update • Patient went to school the following Monday with no neurologic deficits • Patient was readmitted under IM service for Non-accidental Ingestion of 30(?) capsules of diphenhydramine, observed for 24 hours in the wards with unremarkable stay
