Other forms of delusions include, delusions of persecution (“someone is following me”)

or grandeur (“I am a king”).

Disorganized & Delusional Thinking

This morning when I was at Hillside [Hospital], I was making a movie. I was surrounded by movie stars … I’m Mary Poppins. Is this room painted blue to get me upset? My grandmother died four weeks after my eighteenth birthday.”(Sheehan, 1982)

This monologue illustrates fragmented, bizarre thinking with distorted beliefs called delusions (“I’m Mary Poppins”).

Disorganized & Delusional Thinking

Many psychologists believe disorganized thoughts occur because of selective attention

failure (fragmented and bizarre thoughts).

Disturbed Perceptions

A schizophrenic person may perceive things that are not there (hallucinations). Most such hallucinations are auditory and lesser visual,

somatosensory, olfactory, or gustatory.

• …schizophrenics can tickle themselves because of a problem with their timing that does not allow their motor actions and resulting sensations to be correctly sequenced.

• A 20th-century artist, Louis Wain, who was fascinated by cats, painted these pictures over a period of time in which he developed schizophrenia.

• The pictures mark progressive stages in the illness and exemplify what it does to the victim's perception.

Inappropriate Emotions & Actions

A schizophrenic person may laugh at the news of someone dying or show no

emotion at all (flat affect).

Patients with schizophrenia may continually rub an arm, rock a chair, or remain motionless for hours (catatonia).

Onset and Development of Schizophrenia

Nearly 1 in a 100 suffer from schizophrenia, and throughout the world over 24 million

people suffer from this disease (WHO, 2002).

Schizophrenia strikes young people as they mature into adults. It affects men

and women, but men suffer from it more severely than women.

15

Chronic and Acute Schizophrenia

When schizophrenia is slow to develop (chronic/process) recovery is doubtful.

Such schizophrenics usually display negative symptoms.

When schizophrenia rapidly develops (acute/reactive) recovery is better. Such

schizophrenics usually show positive symptoms.

16

Understanding Schizophrenia

Schizophrenia is a disease of the brain exhibited by the symptoms of the mind.

Dopamine Overactivity: Researchers found that schizophrenic patients express higher levels of dopamine

D4 receptors in the brain.

Drugs that block these sites help schizophrenic patients.

Brain Abnormalities

Abnormal Brain Activity

Brain scans show abnormal activity in the frontal cortex, thalamus, and amygdala of

schizophrenic patients.

Viral InfectionSchizophrenia has also been observed in individuals whose mothers contracted a viral infection (flu) during the middle of

their fetal development.

Genetic Factors

The likelihood of an individual suffering from schizophrenia is 50% if their identical

twin has the disease (Gottesman, 2001).

Psychological Factors

Psychological and environmental factors can trigger schizophrenia if the individual

is genetically predisposed (Nicol & Gottesman, 1983).
