Summary
Acute confusional migraine (ACM) presents with prolonged agitation and confusion, primarily in adolescents. This migraine type shows specific EEG abnormalities, suggesting a distinct clinical presentation.
Area of Science:
- Neurology
- Neurophysiology
Background:
- Migraine is a common neurological disorder.
- Acute confusional migraine (ACM) is a rare subtype characterized by altered mental status during headache attacks.
Observation:
- Twelve adolescent patients experiencing ACM were studied.
- Attacks featured prolonged agitation and mental confusion.
- Electroencephalogram (EEG) during attacks revealed diffuse slow abnormalities and frontal intermittent rhythmic delta activity (FIRDA).
Findings:
- Neuroradiologic and laboratory tests were normal.
- EEG patterns normalized after the acute phase.
- ACM shares similarities with juvenile head trauma syndrome.
Implications:
- ACM may represent a unique clinical manifestation of migraine.
- This condition affects higher mental functions.
- Further research is needed to understand the pathophysiology of ACM.
