A new study revealed how marijuana use affects the area of the brain responsible for memory functions.
Mail Online reported that there is an abnormally low blood flow in the brain’s right hippocampus among marijuana users. As shown in the brain scans analyzed by researchers at Amen Clinics, these irregular blood levels were mostly found in areas affected by Alzheimer’s disease.
For the study, researchers looked at a 1995-2015 database involving 26,268 patients with complex treatment-resistant issues from states California, Virginia, Georgia, Washington and New York. 1,000 of these patients were marijuana users, whose brain scans then compared to those of 100 healthy controls.
Using brain scans taken from single photon emission computed tomography (SPECT) — which analyzed the brain’s blood flow and activity patterns as participants went through concentration tests — researchers
