Abnormal Psychology- Schizophrenia Disorder

QuestionAnswer
Schizophrenia A disorder with a range of symptoms involving disturbances in content of thought, form of thought, perception, affect, sense of self, motivation, behavior, and interpersonal functioning.
Dementia Praecox Original name for schizophrenia. A degeneration of the brain that began at a relatively young age ultimately led to the disintegration of the entire personality.
Active Phase 6-month period of symptoms, such as delusions, hallucinations, disorganized speech, disturbed behavior, and negative symptoms (eg., speechlessness, or lack of initiative).
Prodromal Phase Period prior to the active phase which the individual shows progressive deterioration in social and interpersonal functioning.
Residual Phase Active phase is followed by this phase, in which there are continuing indications of disturbance similar to the behaviors of the prodromal phase.
Positive Symptoms Exaggerations or distortions of normal thoughts, emotions, and behavior. Viewed as direct lead-ins to the full expression of psychosis.
Negative Symptoms Those that involve functioning below the level of behavior regarded as normal (eg. affective flattening, alogia, and avoliton).
Affective Flattening An individual seems unresponsive with relatively motionless body language and facial reactions and minimal eye contact.
Alogia Loss of words or notable lack of spontaneity or responsiveness in conversation.
Avolition Lack of initiative and unwillingness to act (eg. stares out window instead of doing something pleasant).

Cortical Atrophy Often accompanied by ventricular enlargement. A wasting away of brain tissue.
Dopamine Hypothesis The delusions, hallucinations, and attentional deficits found in schizophrenia can be attributed to over-activity of neurons that communicate with each other via the transmission of dopamine.
