Understanding Schizophrenia

Learn about schizophrenia

Schizophrenia is a mental health condition that can cause significant impairment in a person’s daily functioning. Known to be one of the most debilitating mental illnesses, this disorder includes symptoms that are so severe that an individual may begin to self-harm or attempt to end his or her own life if treatment is not sought. The positive, negative, and cognitive symptoms can hinder a person from knowing what is real and what is imagined and thinking clearly, and can decrease a person’s ability to express feelings appropriately. Social isolation is common in those with schizophrenia because symptoms can make interacting with the outside world ripe with obstacles, frustrations, and fear. Substance use is also common as those with this condition try to self-medicate to alleviate symptoms. However, with treatment and the inclusion of psychotropic medications that help alleviate symptoms, it is possible that a person can regain healthy functioning and reduce the harmful risks associated with schizophrenia.

Statistics

Schizophrenia statistics

Research estimates that 1% of the total population meets criteria for a schizophrenia diagnosis. With the typical age of onset being between late adolescence and early to mid-adulthood, schizophrenia affects men and women equally. However, experiencing the onset of symptoms over the age of forty-five is uncommon.

Causes and Risk Factors

Causes and risk factors for schizophrenia

Experts believe that a number of factors working in tandem can make a person more susceptible to the development of schizophrenia. Below are the findings associated with this belief:

Genetic: Individuals with an immediate family member who is suffering from schizophrenia make up 10% of those who possess their own schizophrenia diagnosis. Because of this link, researchers have concluded that genetics play a big role in determining whether or not an individual will begin to show signs and symptoms of schizophrenia at some point in his or her lifetime.

Physical: Research has shown that those with schizophrenia have lowered levels of dopamine and serotonin in their brains. When these mood-managing neurotransmitters are at decreased levels, symptoms synonymous with schizophrenia can manifest.

Environmental: Scientists have found that certain environmental factors can cause a person to develop schizophrenia. Malnutrition and exposure to certain viruses while a baby is in utero have led some people to display signs and symptoms associated with schizophrenia. Additionally, complications that occur during childbirth can cause the onset of schizophrenia at some point in a person’s lifetime.

Risk Factors:   

  • Family history of schizophrenia or other mental illnesses
  • Personal history of mental illness or undiagnosed mental illness
  • Preexisting autoimmune disease
  • Being born to a father who is of advanced age
  • Prenatal exposure to poor nutrition or viruses
  • Consuming mood-altering substances

My husband and I felt like we didn't know who our son was anymore because of how he was acting out at home and in school. After completing inpatient treatment at StoneCrest, he's stable, respectful, and the happy boy we knew him to be. Thank you StoneCrest!
