Epilepsies..........................................


MICHAEL J. AMINOFF, MD, DSc

history & physical
■History of recurrent seizures (ie, stereotyped episodes of motor, sen-
sory or behavioral disturbance or LOC)
■Seizures occur unpredictably but may be precipitated by certain sit-
uations (eg, stress, sleep deprivation, flickering lights)
■Pt may be unaware of seizure occurrence
■Seizures may be followed by headache, confusion, drowsiness or
focal deficits
■May be history of preceding CNS injury or infection, drug or alcohol
abuse
■May be family history of epilepsy
■May be no abnormal finding
■Focal abnormalities in pts w/ underlying structural disorder
■Cognitive deficits or multifocal or generalized deficits if seizures sec-
ondary to diffuse cerebral pathology
■Dysmorphic features or cutaneous abnormalities in certain epileptic
syndromes

tests
■Lab tests: CBC, differential count, FBS, Ca, liver & kidney function
tests, VDRL
■EEG to support diagnosis & to characterize, localize & determine
prognosis of seizures
■Cranial CT scan or MRI: to detect underlying structural lesion (espe-
cially w/ focal seizures or seizure onset after age 20 yr)

differential diagnosis
■TIAs distinguished from focal seizures by their lack of spread & neg-
ative symptomatology (loss of motor or sensory function)
■Panic attacks usually relate to external circumstances; may be evi-
dence of psychopathology btwn attacks
■Rage attacks consist of goal-directed aggressive behavior
■Syncopal attacks preceded by sweating, nausea, malaise, pallor; LOC
assoc w/ little (if any) motor activity, recovers rapidly w/ recumbency,
no postictal confusion
■Cardiac arrhythmia: may be history of cardiac disease, heart murmur
or arrhythmia; attacks may relate to physical activity
