Diffusion Tensor Imaging (DTI) may provide information regarding effects of 3,4-methylenedioxymethamphetamine (MDMA) use on brain structure. Twelve MDMA users and 20 healthy controls underwent whole brain DTI data acquisition. Fractional anisotropy (FA), mean diffusivity (D(av)), and longitudinal (lambda(1)) and transverse (lambda(T)) diffusivities were compared between MDMA users and controls...
Methylene-dioxymethamphetamine (MDMA) is known to cause degeneration of serotonin nerve terminals after acute doses in animals. Similarly, behavioral studies in human MDMA users regularly find abnormalities in memory, mood, and impulse control. However, studies of brain function using brain imaging in MDMA users have been less consistent. The purpose of this study was to determine, using...
