Metadimensional Extroversion Syndrome (MES)

Metadimensional Extroversion Syndrome, or MES for short, is a chronic cerebral syndrome first witnessed in 2240 during the First Wave of Colonization. Based on the frontal cortex, this syndrome occurs mostly within groups undergoing extensive space travel and matures during the first stages of puberty. MES has varying effects on different patients, wherein some learn to see into the future or attain superluminal teleportation.

Characteristics
Relatively few worlds have recovered the basics of psionic training, but at most psychic academies people undergo individualized training in a range of disciplines from telekinesis to telepathy. Psychics tend to require extensive rest between the active use of their powers, as the mental and physical strain causes irreparable damage to the frontal cortex resulting either in complete burnout or madness.

Patients diagnosed as mentally unstable due to extreme psychic pressure tends to be able to use their powers with no limits, and usually does, as the burnout seems to make the subjects immune to further brain damage.
