Schizophrenia is a condition that usually affects the way individuals feel, think, and behave. People living with schizophrenia can experience hallucinations, delusions, trouble thinking, disorganized speech, and lack of motivation, among other symptoms. In general, schizophrenia is not life-threatening. The condition may not be curable, but schizophrenia can be treatable, and many people who receive treatment experience relief from symptoms.

Understanding schizophrenia as a mental illness

Schizophrenia can be seen as a complex and misunderstood condition. Many people believe the misconception that people with schizophrenia are dangerous or violent, but research suggests that this is not true. Rather, people with schizophrenia tend to be more likely to be the targets of crimes, although updated evidence may be needed.

Many people also believe that schizophrenia is the same as dissociative identity disorder (DID, previously called multiple personality disorder). However, the two conditions are distinct, and people with schizophrenia do not typically have multiple identities or personalities. Schizophrenia and DID may sometimes be comorbid, with both conditions appearing in the same person, but this is rare. 

Who can develop schizophrenia?

Anyone from any background can develop schizophrenia. The condition usually affects men and women equally, although men may experience symptoms sooner than women. The exact cause of the condition is currently unknown, but potential risk factors include the following:

  • A family history of schizophrenia
  • Certain pregnancy and birth complications
  • Using psychoactive or psychotropic substances during teen years and early adulthood

Can schizophrenia kill you? 

Schizophrenia itself is not considered life-threatening. However, people who have schizophrenia may be more likely to have other health conditions, like diabetes, lung cancer, and cardiovascular disease, that may raise their risk of premature mortality. Due to these conditions and the fact that approximately 80% to 90% of people with schizophrenia are smokers, life expectancy for people with schizophrenia can be lower than that of the general public.

Additionally, people with schizophrenia tend to be more likely to develop alcohol use disorders, struggle to maintain nutrient-rich eating habits and regular exercise routines, and may also avoid regular medical care. All of these factors can contribute to a lower life expectancy. Providing flexible and equitable resources and healthcare for people with schizophrenia can improve their life expectancy.

Symptoms of schizophrenia

People with schizophrenia do not always experience active symptoms. Some people with the condition may go for long periods of time without experiencing any symptoms, especially if they are receiving treatment. However, people with active schizophrenia symptoms may experience the following: 

Psychosis

Psychosis can serve as an umbrella term that describes a state in which someone experiences a disconnect from reality. Psychosis can take many forms. Some people with schizophrenia may hear and see things that aren’t there, while others may become paranoid or fixated on specific ideas. 

Delusions

Delusions typically refer to false beliefs that are not based in reality. Some may have delusions that others are trying to harm them; others may have delusions in which they think another person is in love with them. Some may become convinced that a disaster is about to occur, and others may think certain comments or behaviors are directed at them when they are not. For people with schizophrenia, delusions tend to be a common symptom, and though they may be hard for others to understand, they usually seem very real for the person with schizophrenia. 

Hallucinations

People with schizophrenia can experience hallucinations, or sensory experiences that are not triggered by real stimuli. Like delusions, hallucinations usually seem very real for people who experience them. Older studies suggest that around 70% of people with schizophrenia may experience hallucinations, and the most common manifestation can be hearing voices.

Abnormal speech and thinking

People with schizophrenia may speak in a monotone or use jumbled phrases and sentences. They may also speak much less than usual, or, in some cases, speak quickly and rapidly shift between topics. They may also use made-up words and repeat themselves often.

Abnormal movement

Motor skills can be significantly affected by schizophrenia. This can result in strange movements, bizarre or inappropriate posture, or excessive and repetitive motions. People with schizophrenia may also struggle to follow instructions, have trouble making eye contact, and make abnormal facial expressions. 

Other symptoms of schizophrenia 

Other symptoms may include those listed below:

  • Social withdrawal
  • Lack of motivation
  • Neglect of hygiene and appearance
  • Childlike behavior
  • Agitation
  • Loss of interest in usual activities 

Schizophrenia symptoms usually begin to arise in a person’s early to mid-twenties. Childhood schizophrenia and schizophrenia appearing in those over the age of 45 do exist, although this is rare.

Schizophrenia treatment options

Left untreated, schizophrenia can cause significant problems in a person’s professional, social, and personal lives. Untreated schizophrenia may lead someone to experience job loss, social isolation, health problems, financial problems, and even suicidal ideation. With treatment, people with schizophrenia can live fulfilling and functional lives.

Treatment options for schizophrenia normally include medication, therapy, and lifestyle changes. Schizophrenia treatment is generally lifelong. 

Medications, particularly antipsychotic medications, can provide significant improvements in schizophrenia symptoms. Other medications, like antidepressants and anti-anxiety medications, are also prescribed in some cases. Certain antipsychotics may come in an injectable form to be administered every two to four weeks, which can be helpful for people who struggle to stick to a medication schedule. 

Some antipsychotics have side effects, so consult with your doctor to find a medication that works well for you. Never start, stop, or change the way you take medication without consulting your doctor or psychiatrist. 

Working with mental health professionals

Psychotherapy can also be an effective treatment option for schizophrenia, alongside medication. Working with mental health professionals can help individuals normalize thought patterns, develop new coping strategies, and identify warning signs of a schizophrenic episode or relapse. Therapy can be done face-to-face, in a support group setting, or online. 

Online therapy may be a particularly convenient option since this format usually allows individuals to meet with a therapist from the comfort of their homes. Additionally, online therapy can be more affordable, and scheduling is typically more flexible than traditional, in-office therapy.

Because online therapy can produce the same client outcomes as in-office therapy, this format may be a valid treatment option for those with mental health disorders like schizophrenia. However, those currently experiencing acute psychotic symptoms may need to seek care in person. Outside of psychotic episodes, online therapy may be an effective way to support those living with schizophrenia in an attainable and convenient way.

Takeaway

Schizophrenia is a serious mental illness that is typically characterized by symptoms of psychosis, delusions, hallucinations, and impaired motor skills. The condition can be widely misunderstood, but many people are now fighting the stigma and working to educate the public about schizophrenia, the mortality gap, and how we can best support those living with mental illnesses. While schizophrenia is generally not seen as a life-threatening condition, those with the disorder may have a higher risk of early death. However, professional treatment, such as doctor-prescribed medication and regular in-person or online therapy sessions, may reduce this risk.
