A Case of Transient Global Amnesia Due to Marijuana Use

Transient global amnesia (TGA) has been a well-described phenomenon for more than 40 years. It presents with a paroxysmal, transient loss of memory. Immediate recall ability and remote memory are preserved. However, patiens experience striking loss of memory for recent events and an impaired ability to retain new information. In some cases, the degree of retrograde memory loss is mild. Marijuana induced transient global amnesia is a rare side effect. Here, we present a case of memory loss for a short period of time after use of marijuana.
