Christine Bays



  • “Schizophrenia is a mental disorder that makes it hard to: Tell the difference between what is real and not real, think clearly, have normal emotional responses, and act normally in social situations.”

  • Beliefs that have no basis in reality (delusions)

  • Hearing, seeing, feeling, smelling, or tasting things that have no basis in reality (hallucinations)

  • Disorganized speech

  • Disorganized behaviors

  • Catatonic behaviors

Types of schizophrenia

Types of schizophrenia

  • Paranoid schizophrenia

  • Disorganized schizophrenia

  • Catatonic schizophrenia

  • Undifferentiated schizophrenia

  • Residual schizophrenia

Paranoid schizophrenia

Paranoid schizophrenia

  • “People will have delusions and auditory hallucinations but relatively normal intellectual functioning. The delusions can often be about being persecuted unfairly or being some other person who is famous.”

  • Side affects: anger, aloofness, anxiety, and argumentativeness.

Disorganized schizophrenia

Disorganized schizophrenia

  • “Disorganized-type schizophrenia is characterized by speech and behavior that are disorganized or difficult to understand, and flattening or inappropriate emotions. People with disorganized-type schizophrenia may laugh at the changing color of a traffic light or at something not closely related to what they are saying or doing. Their disorganized behavior may disrupt normal activities, such as showering, dressing, and preparing meals.”

Catatonic schizophrenia

Catatonic schizophrenia

  • “They have disturbances of movement. People with catatonic-type schizophrenia may keep themselves completely immobile or move all over the place. They may not say anything for hours, or they may repeat anything you say or do senselessly.”

  • “It impairs their ability to take care of themselves.”

Residual schizophrenia

Residual schizophrenia

  • “Residual-type schizophrenia is characterized by a past history of at least one episode of schizophrenia, but the person currently has no positive symptoms (delusions, hallucinations, disorganized speech or behavior). It may be a full-blown episode, or it may continue for years without any further psychotic episodes.”

Undifferentiated schizophrenia

Undifferentiated schizophrenia

  • “Undifferentiated-type schizophrenia is characterized by episodes of two or more of the following symptoms: delusions, hallucinations, disorganized speech or behavior, catatonic behavior or negative symptoms, but they don’t seem like they have paranoid, disorganized, or catatonic type of schizophrenia.”

Causes of schizophrenia

Causes of schizophrenia

  • “There is no single cause for schizophrenia. Rather, it is the result of a complex group of genetic, psychological, and environmental factors. Environmentally, the risks of developing schizophrenia can even occur before birth. For example, the risk of schizophrenia is increased in individuals whose mother had one of certain infections during pregnancy.

  • Difficult life circumstances during childhood, like the early loss of a parent, parental poverty, bullying, witnessing parental violence; emotional, sexual, or physical abuse; physical or emotional neglect; and insecure attachment have been associated with the development of this illness”

Tests for schizophrenia

Tests for Schizophrenia

  • Tests and screenings. They do a complete blood count (CBC), and the doctor may also request imaging studies, such as an MRI or CT scan.

  • Psychological evaluation. A doctor or mental health provider will check mental status by observing appearance and demeanor.



  • “Prescription drugs can reduce symptoms such as abnormal thinking, hallucinations, and delusions. It's thought they work by regulating certain brain chemicals and receptors that influence thinking, perception, and behavior.”
