FAAH and frontotemporal dementia: Assuming that changes in FAAH and endocannabinoid concentrations may be part of an endogenous protective response elicited by the neurodegenerative process in FTD mice, our next experiment was aimed at investigating the effects of the pharmacological inactivation of this enzyme, a treatment that is well-documented to elevate anandamide levels [59], which may enhance such endogenous protective response.
