Interictal type 1 cannabinoid receptor binding is increased in female migraine patients.

“BACKGROUND:

It has been suggested that endocannabinoid deficiency may play a role in the pathophysiology of migraine. Nonetheless, biochemical studies substantiating this idea remain scarce and are faced with methodological shortcomings partly because of the difficulty to perform measurements of endocannabinoids within the central nervous system itself.

CONCLUSION:

The increased interictal CB1R binding, especially in brain regions that exert top-down influences to modulate pain, supports the idea that endocannibinoid deficiency is present in female patients suffering from episodic migraine.”
