Summary
Migraine attacks significantly alter plasma levels of neuroexcitatory amino acids, specifically glutamic and aspartic acid. These changes occur only during attacks, not between them, suggesting a link to migraine mechanisms.
Area of Science:
- Neuroscience
- Biochemistry
Background:
- Migraine is a complex neurological disorder.
- Neuroexcitatory amino acids play a role in neuronal function.
Purpose of the Study:
- To investigate plasma levels of neuroexcitatory amino acids during and between migraine attacks.
- To compare these levels in patients with migraine with and without aura, and in controls.
Main Methods:
- Plasma samples were collected from 16 migraine without aura patients, 11 migraine with aura patients, and 21 controls.
- Levels of glutamic acid and aspartic acid were measured.
Main Results:
- No significant variations in neuroexcitatory amino acids were observed between migraine attacks.
- Plasma levels of glutamic acid and aspartic acid decreased significantly during migraine attacks in both patient groups.
- Control group levels remained stable.
Conclusions:
- Changes in neuroexcitatory amino acids occur specifically during migraine attacks.
- These fluctuations may be related to the spreading depression process implicated in migraine pathophysiology.
