Understanding Schizoaffective Disorder

Learn about schizoaffective disorder

Schizoaffective disorder is a mental illness in which an individual experiences symptoms of schizophrenia, such as delusions and/or hallucinations, as well as mood disorder symptoms, like depression and/or mania. This psychiatric condition is comprised of a combination of many different symptoms of varying severity that affect everyone who is diagnosed with the disorder in various ways.

Without proper treatment, individuals with schizoaffective disorder may have problems holding down a job or difficulty functioning at home or in school. They may have problems with social relationships, either completely isolating themselves from friends or family, or becoming completely dependent upon them. The psychotic symptoms that are associated with this disorder have a significant effect on thinking, decision-making, concentration, memory, and problem-solving skills. In addition to these cognitive impairments, individuals often experience delusions, disorganized speech, and paranoia. Due to the severity of these psychotic symptoms, individuals with schizoaffective disorder sometimes have difficulty distinguishing reality from an imagined reality, which can make functioning in society particularly difficult.

The psychotic features and mood symptoms of this disorder can occur at the same time, or can occur on and off interchangeably. While there is some fluctuation in the presentation of symptoms, the course of this disorder usually presents in a cyclical pattern in which periods of severe symptoms are followed by a return to baseline functioning.

In most cases of schizoaffective disorder, the onset of symptoms typically occurs after the age of 13, with the majority of individuals being diagnosed in early adulthood. Fortunately, newer treatments for schizoaffective disorder and accompanying mood disorders have proven effective in the management of the symptoms and effects of this condition, thus helping those with this disorder re-establish a normal and fulfilling life.

Statistics

Schizoaffective disorder statistics

As one of the less commonly diagnosed mental health conditions, the lifetime prevalence rate for schizoaffective disorder has been estimated at about 0.3%. Higher rates of this disorder have been found in women than in men, which may be due to the fact that women suffer from higher rates of depression. There are also differences in the way schizoaffective disorder presents in men and women. Men report having more psychotic symptoms and a longer illness duration, while women tend to experience more mood symptoms for a shorter period of time.

Causes and Risk Factors

Causes and risk factors for schizoaffective disorder

The exact cause for the development of schizoaffective disorder in unknown, but it may involve a number of factors such as brain chemistry, an imbalance of hormones, and other environmental factors, some of which are described below.

Genetic: Similar to schizophrenia, schizoaffective disorder has proven to have distinct genetic links. Those with first-degree relatives who have schizophrenia, schizoaffective disorder, or a mood disorder are at a higher risk for developing this disorder than those who do not have a similar family history.

Physiological: Certain chemicals in the brain that are responsible for the communication between neurons, which are called neurotransmitters, have been linked to the development of schizoaffective disorder. More specifically, it has been suggested that when dopamine and serotonin are at abnormal levels, this may contribute to the development of schizoaffective disorder.

Environmental: Research has demonstrated that being exposed to toxins or viruses in the womb may contribute to the later development of this disorder. Additionally, it is also possible that birth complications may be related to the development of schizoaffective disorder.

Risk Factors:

  • Family history of mood disorders
  • Family history of schizophrenia or schizoaffective disorder
  • Being exposed to certain toxins or viruses prenatally
  • Suffering from complications at birth
