Schizophrenia affects men and women in equal numbers; although on average, men appear to develop schizophrenia earlier than women. Generally, men show the first signs of schizophrenia in their mid 20s and women show the first signs in their late 20s. Schizophrenia has a tremendous cost to society, estimated at $32.5 billion per year in the US. (Keefe 104) The behavior of people with schizophrenia is often very strange and shocking. This change in behavior, when people cannot tell the difference between what is real and what is not, is called "psychosis" or a "psychotic episode." The American Psychiatric Association has pu

1. Delusions, bizarre, false beliefs

(5) Catatonic posturing (voluntary assumption of inappropriate or bizarre postures)

B) Visual (seeing lights, objects or faces)

In a Twin study conducted by Dr. Michael Coleman, tendency for both monozygotic (identical) twins to develop schizophrenia is between 30-50%. The tendency for dizygotic (fraternal) twins to develop schizophrenia is about 15%. The tendency for siblings who are not twins (like siblings of different ages) is also about 15%. Remember, schizophrenia is found in the general population at a rate of about 1%. Therefore, since the tendency for monozygotic twins is NOT 100%, genetics isn’t the only factor. However, since the tendency for monozygotic twins to have schizophrenia is much greater than that of dizygotic twins, genetics DOES play a role.

Associated features of Catatonic Schizophrenia include stereotypes, mannerisms, and waxy flexibility. Mutism is particularly common. During catatonic stupor or excitement, the person needs careful supervision to avoid hurting him or herself or others.

C) Olfactory (smelling things)
