| Key findings | The authors report an individual with no prior psychiatric history who developed panic disorder after a single typical dose of MDMA, which they describe as the first such report. They suggest that some people may have increased susceptibility to MDMA's adverse psychiatric effects, though they note that earlier reports of lasting sequelae mostly involved repeated high doses and individuals with prior psychiatric histories. |
Abstract
( +_ )3,4-Methylenedioxymethamphetamine (MDMA) is a synthetic amphetamine analogue used recreationally by humans in the United States (Pcroutka 1987) and Western Europe (Anon 1992), and is thought by some to have potential utility as a psychotherapoutic adjunct (Grinspoon and Bakalar 1986). It is generally believed that MDMA acts via central monoamines, primariJy by inducing transmitter release and interfering with monoamine reuptake inactivation (Johnson et al 1991; McKenna and Peroutka 1990). In animals, MDMA has been shown to damage brain serotonin neurons, and in the monkey the neurotoxic dose closely approximates the dose typically ingested by humans (Ricaurte et al 1988). Concern that MDMA may damage serotonin neurons in the human brain is largely responsible for MDMA's Schedule I status in the United States, and consequently, the dearth of controlled studies comparing the risks of MDMA to its possible benefit as a therapeutic adjunct. There have been several recent reports of lasting adverse neuropsychiatric sequelae in humans who have taken repeated (usually high) doses of MDMA (Crcighton et al 1991; Benazzi and Mazzoli 1991; McGuir¢ and Fahy 1991; Schifano 1991; McCann and Ricaurte 1991). These reports suggest that individuals with prior psychiatric histories may have an increased susceptibility to MDMA's adverse effects. Lingering psychiatric syndromes associated with MDMA ingestion have included chronic paranoid psychosis (Schifano 1991; McGuir¢ and Fahy 1991), recurrent acute paranoid psychosis (Crcighton et al 1991), depression with suicidality (Benazzi and Mazzoli 1991), and panic disorder with secondary depression (McCann and Ricaurte 1991). Although untoward effects of high neurotoxic doses of MDMA might be anticipated, particularly in vulnerable individuals, enduring psychiatric illness following a single moderate dose of MDMA in a healthy individual has not been reported. We describe an individual with no prior psychiatric history who developed panic disorder after ingesting a single typical dose of MDMA.
