Abstract

The endocannabinoid (EC) system influences a wide variety of neurobiological processes including affect and emotionality as well as other neuropsychiatric functions. In this study we examined the relationship of circulating endocannabinoids [anandamide (AEA) and 2-arachidonoylglycerol (2-AG)] with affect and emotionality in 175 individuals with (n = 115) and without (n = 60) mood, anxiety, and/or personality disorders. Circulating AEA levels displayed a modest, though statistically significant, inverse relationship with a composite measure of affect regulation (β = − 0.264, p = 0.009), due to its relationship with affect intensity (β = − 0.225, p = 0.021) across all study participants. Neither AEA nor 2-AG level differed as a function of any syndromal/personality disorder and neither correlated significantly with state depression or state anxiety scores. These data suggest that circulating levels endocannabinoids may play a role in emotionality across individuals regardless of defined psychiatric disorder.
