Traumatic events or seemingly unsolvable problems can lead to a psychic reaction known as conversion. The unsolvable problem is deferred resulting in disturbances which the person concerned can no longer trace back to the basic event.

The problem may be deferred to the following scopes:

  • Psyche: this path may lead to amnesia, flight (fugue), stupor, trance, obsession, loss of identity
  • Motor system: may lead to weakness, palsy, dystonia, disturbances in coordination and loss of hold
  • Sensibility: may lead to paraesthesia, prickling and physical numbness
  • Brain: may lead to epileptic-like fits
