Hypomania as an aura in migraine.
We report a 19-year-old man presenting to the department of Psychiatry for the evaluation of prominent behavioral symptoms associated with episodic headaches, with normal inter-episodic periods. A diagnosis of classic migraine with hypomanic aura was made. Other possible co-morbid or causative illnesses were excluded and preventive therapy with valproate was started due to the prominent affective symptoms as a part of the migranous aura. With this the frequency of headaches gradually decreased over the next four months. He was followed up for 2 years when he was found to be symptom-free. Recent research into the mechanisms of migraine has identified that the cortical hyperexcitability and an imbalance between neuronal inhibition and excitement mediated by gamma-aminobutyric acid and excitatory amino acids respectively may be the underlying mechanism. The high rate of affective disorders in patients with migraine, association of migraine with an aura comprising of mood symptoms and good response to treatment with mood-stabilisers might give newer insights into the pathophysiology of mood disorder as well.
