Understanding Schizophrenia

Learn about Schizophrenia

Schizophrenia, a mental health condition that can hinder a person’s functioning in several ways, includes symptoms that can be debilitating for a person if treatment is not received to alleviate symptoms. Individuals who suffer from this disorder frequently struggle to form coherent thoughts and speech, have a hard time deciphering between what is real and what is not, and present with behaviors that may seem odd to others. Additionally, the symptoms of this disorder can cause a great deal of distress as the hallucinations and delusions that are often present can increase a person’s anxiety and lead to intense feelings of paranoia.

Sufferers of schizophrenia are often at risk of abusing drugs and/or alcohol, as these individuals find false solace in escaping their distressing symptoms through substance use. Furthermore, people with this mental health condition may develop ideations of suicide or attempt to take their own lives as schizophrenia can cause a number of seemingly unbearable obstacles for a person on a daily basis. Fortunately, there are options for treatment available that can help individuals who are battling Schizophrenia. Through the use of medications and other therapeutic interventions, people grappling with schizophrenia can find relief from symptoms and restore healthy functioning.


Schizophrenia statistics

The average age of onset for symptoms of schizophrenia is believed to be between late adolescence and mid-adulthood. Research has also found that men and women are equally affected by this mental illness. Lastly, in terms of the prevalence of this disorder, estimates suggest that approximately 1% of the overall population suffer from schizophrenia.

Causes and Risk Factors

Causes and risk factors for schizophrenia

Professionals in the field of mental health agree that there are a number of causes and risk factors that can lead a person to suffer from schizophrenia. Research cites genetics, physiological composition, and environmental influences as the main contributors to the development of this illness. Consider the following explanations and risk factors that explain the causes for schizophrenia:

Genetic: Because of prevalence rates of schizophrenia among members who share similar genes, experts have concluded that this disorder is genetic. In fact, studies have found that 10% of individuals with schizophrenia have a biological family member with the same mental health history. In sum, a person’s genetic can be a determinant for an eventual diagnosis of schizophrenia.  

Physical: Similar to other mental health disorders, those with schizophrenia are known to have certain chemical imbalances in their brains. Serotonin and dopamine, more specifically, are neurochemicals that are responsible for regulating mood and have been found at lower levels in those with this mental illness. Additionally, neuroimaging studies have found that individuals with schizophrenia have differing brain structures that can cause symptoms of this condition to manifest.

Environmental: Research has found that there are a number of environmental influences that can trigger the onset of schizophrenia symptoms. If a person is exposed to poor nutrition or certain viruses while in utero, there is an increased risk that an individual will develop this disorder. Additionally, some experts believe that complications during the childbirth process can make a person susceptible to displaying symptoms of schizophrenia later in life. Lastly, mental health professionals believe that certain mind-altering drugs can trigger the onset of this disorder as certain substances can significantly alter a person’s brain chemistry.

Risk Factors:  

  • Prenatal exposure to poor nutrition
  • Prenatal exposure to viruses
  • Preexisting autoimmune disease
  • Family history of schizophrenia or other mental health condition(s)
  • Personal history of mental health conditions(s)
  • Presence of undiagnosed mental health condition(s)
  • Being born to a father who is of advanced age
  • Abusing mind-altering drugs
