Cerebral1H MRS alterations in recreational 3,4-methylenedioxymethamphetamine (MDMA, ?ecstasy?) users

Journal of Magnetic Resonance Imaging October 1, 1999 L. Chang, Thomas Ernst, Charles S. Grob et al. 109 citations

Recreational use of MDMA does not cause significant neuronal injury, as indicated by normal levels of N-acetyl compounds in the brain. However, in the parietal white matter, the concentration of myo-inositol was 16.3% higher and the ratio of myo-inositol to creatine was 14.1% higher in MDMA users compared to non-users. These increases, which were related to the cumulative lifetime dose of MDMA, suggest that even recreational doses may lead to increased glial content in the brain. The study involved 22 MDMA users and 37 normal subjects, using magnetic resonance imaging and spectroscopy to assess neurochemical abnormalities.

Cerebral 1H MRS alterations in recreational 3,4‐methylenedioxymethamphetamine (MDMA, “ecstasy”) users

Journal of Magnetic Resonance Imaging October 1, 1999 L. Chang, T. Ernst, C.s. Grob et al. 28 citations

Recreational use of MDMA (ecstasy) may increase glial content in the brain without causing significant neuronal injury. In a comparison of 22 MDMA users and 37 non-users, magnetic resonance spectroscopy showed normal levels of N-acetyl compounds, indicating no major neuronal damage. However, MDMA users had a 16.3% higher concentration of myo-inositol and a 14.1% higher myo-inositol-to-creatine ratio in parietal white matter, with effects linked to cumulative lifetime MDMA dose. These findings suggest that even recreational MDMA exposure may alter brain glial cells.
