Classic migraine attack complicated by confusional state: EEG and CT study.

|June 1, 1985
Summary
This study observed electroencephalographic (EEG) changes during a classic migraine attack with confusion. Slow brain waves in the left hemisphere normalized over four days, suggesting a link to impaired consciousness.
Area of Science:
- Neurology
- Neurophysiology
Background:
- Classic migraine is a neurological disorder characterized by severe headaches.
- Migraine attacks can sometimes present with complex neurological symptoms beyond pain.
Observation:
- Electroencephalographic (EEG) and clinical data were collected during a classic migraine attack.
- The patient experienced a confusional state accompanying the migraine.
- Ictal EEG revealed slow wave activity predominantly over the left cerebral hemisphere.
Findings:
- The left hemispheric EEG abnormality gradually resolved within four days post-attack.
- Brain CT scans performed during and after the attack showed no structural abnormalities.
- A correlation between the confusional state and potential left hemispheric metabolic dysfunction is hypothesized.
Implications:
- This case highlights the potential for focal EEG abnormalities during migraine with aura and confusional states.
- It suggests a possible link between transient cerebral dysfunction and migraine pathophysiology.
- Further research into the neurophysiological underpinnings of migraine-induced cognitive changes is warranted.
