Seizure Type with Eyes Rolling Up and Arm Crossing

Key Distinguishing Features

The clinical presentation of eyes rolling upward with arm crossing most likely represents a focal seizure with secondary generalization or a generalized tonic-clonic seizure, though the specific arm positioning (crossing) may indicate asymmetric tonic posturing suggestive of focal onset 1, 2
Eyes rolling upward is a common feature during the tonic phase of both generalized-onset and focal-onset bilateral tonic-clonic seizures 1, 2
Arm crossing or asymmetric arm posturing strongly suggests focal onset rather than primary generalized seizures, as symmetrical movements are more typical of generalized-onset seizures 1, 2

If the abnormal posturing begins BEFORE the fall, this indicates epilepsy (likely focal onset) 1, 2
If movements are asymmetrical or restricted to one side, focal seizure is more likely 1, 2
Keeling over stiffly suggests tonic phase epilepsy, whereas flaccid collapse suggests syncope 1
Duration of loss of consciousness: >1 minute strongly favors seizure over syncope (mean 74-90 seconds for seizures vs. 20 seconds for syncope) 1
Presence of aura: Rising abdominal sensation, unusual smell/taste, or déjà vu suggests focal seizure with secondary generalization 1, 2
Post-ictal state: Prolonged confusion or sleepiness lasting more than a few minutes, muscle aches, or tongue biting (especially lateral tongue) points to epilepsy 1, 2

Do not assume all movements indicate epilepsy: Syncope can produce myoclonic jerks, but these are typically asynchronous, limited in scope, and occur AFTER the fall 1, 2
Do not rely on urinary incontinence to differentiate seizure from syncope—it occurs in both 1, 2
Eyes closed during unconsciousness suggests psychogenic pseudoseizure or psychogenic pseudosyncope, NOT epilepsy 1
Pelvic thrusting suggests psychogenic non-epileptic seizures or rarely frontal lobe seizures 1
Prolonged duration (>5 minutes) suggests psychogenic non-epileptic seizures rather than true epileptic seizure 1

Obtain detailed eyewitness account focusing on timing of movements relative to loss of consciousness 1, 2
Check for structural causes (hippocampal sclerosis, cortical dysplasia) if focal onset is suspected, as these are associated with secondary generalization 3
Consider EEG within 24 hours (diagnostic yield 51%) 4
Evaluate for metabolic triggers (hypocalcemia, hypomagnesemia) that can provoke seizures 3, 4
