Document Summary

Unusual thinking, distorted perceptions, and odd behaviour. Hallucination: false sensory perception, feeling spiders, hearing planes seeing people. Do not think logically, perceive the world accurately, or behave in a way that permits normal everday life and work. Emil kraepelin: called it dementia (pervasive disturbances of perceptual and cognitive faculties) praecox (early life onset) Delusions (persecutory (someone"s out to get me) and of influence (people can read my mind)) Not what everyone else is experiencing: presence dos not always = schizophrenia. Loose associations (derailment): sky"s blue, waters, blue the beach, train went off the track, no real sense no logical connection. Clang associations: speech is governed by words that sound alike. Catatonia (awake but nonresponsive to external stimulation) and waxy flexibility (parts of body remain frozen in a particular posture) Anhedonia and blunted feelings (affect): don"t get pleasure out of anything that they do, don"t show any emotion: fig. Negative symptoms - normal people have these and schizophrenics don"t.
