Case Reports
Neuropsychiatric consequences (atypical psychosis and complex-partial
seizures) of ecstasy use: possible evidence for toxicity–vulnerability
predictors and implications for preventative and clinical care
Psychiatric University Hospital Zurich, Zürich, Switzerland.
Two case reports of ecstasy abuse and its serious neuropsychiatric complications are presented. The first
patient developed a florid paranoid psychosis resembling schizophrenia after repeated long-term
recreational ecstasy abuse, and significant alterations with intermittent paroxysmal discharges were found
in his electroencephalogram. The second patient showed an atypical paranoid psychosis with Fregoli
syndrome and a series of complex-partial epileptic seizures with secondary generalization after a first
single ecstasy dose. Both subjects presented considerable vulnerability; the first a minimal brain
dysfunction after perinatal asphyxia and a persisting attention deficit/hyperactivity disorder, the second a
long-lasting opioid addiction. In vulnerable individuals, dose-independent ecstasy abuse can lead to
unpredictable and potentially dangerous neuropsychiatric sequelae which require proper initial
