Posterior reversible encephalopathy syndrome (PRES) following cannabis consumption: A rare association.

Posterior reversible encephalopathy syndrome (PRES) is a clinical-radiological syndrome that combines nonspecific neurological manifestations, sometimes severe (coma, status epilepticus), with typical brain imaging showing mostly bilateral, symmetrical abnormalities, predominantly affecting the white matter. Termed "reversible," the norm is a return to the previous neurological state. However, this recovery is not always guaranteed, with potential neurological sequelae or even progression to death.
