Iresine Syndrome

From Memory Alpha, the free Star Trek reference

Iresine Syndrome is a medical condition first diagnosed in the 23rd century, in which victims fall into a coma. It is characterized by electropathic residue and decreased histamine count.

Telepathic memory invasion committed by the Ullian memory historian Jev in 2368 was misdiagnosed as Iresine Syndrome on a number of worlds he had previously visited. This diagnosis was ruled out by Dr. Crusher as the victims did not present decreased histamine counts. (TNG: "Violations")
