Schizophrenia

Schizophrenia

Verified by World Mental Healthcare Association

Schizophrenia is a severe psychiatric disorder that affects a person’s thoughts, perceptions, behavior, and how they perceive reality.

What Is Schizophrenia?

Schizophrenia is a mental disorder involving hallucinations (perceiving things that aren’t actually present) and delusions (false beliefs about oneself and the world).

It is also characterized by thought disorders and dysfunctions in speech, movement, and behavior. Schizophrenia can have a disabling effect on the people suffering from it. However, the severity of the condition mostly depends on individual factors.

The term “schizophrenia” was originally coined in 1908 by Swiss psychiatrist Eugen Bleuler 1. It is derived from the Greek words schizo meaning “splitting” and phren meaning “mind”.

Case Example

Mr. Mehra had retired from his job as a Manager about 5 years ago and had been living alone since then. His children were working in different cities and would come to visit him about once a year.

For the past 6 months, a generally extroverted Mr. Mehra had been showing increasing signs of social withdrawal. On more than one occasion, his househelp found him talking to the walls as though someone was actually there. He often complained that he could hear the neighbor’s son taunting him every time he got up to do anything – such as open his cupboard, or take a book from the shelf. This constantly hindered his daily activities. It was clear that the taunts that Mr. Mehra was hearing was not real; however, he would get extremely agitated if his claims were ever challenged and would accuse everybody of plotting against him. He was quite convinced that the entire world was coming to get him. 

Soon, he was beginning to appear quite disheveled and was gradually losing a sense of what was real and what wasn’t. After a failed attempt at taking his own life, Mr. Mehra was admitted to the hospital.

Case Analysis
From the case study, it is evident that Mr. Mehra has been experiencing hallucinations (seeing/ hearing things that others can’t) and paranoid delusions about the neighbor’s son being after him and the entire world being against him. These are classic symptoms of schizophrenia of the paranoid type. 

Early Warning Signs Of Schizophrenia

Schizophrenia can occur at any age and can last from months to years. The initial signs differ depending on age and gender. The period in which early warning signs are experienced is called the prodromal stage 2.

For instance, in children, the early signs include severe developmental delay (like slow motor development, delay in speech, etc.) and impaired social development. In adolescents, young adults, and elderly people, the initial signs and symptoms of schizophrenia are more or less similar. Some of these include:

  1. Agitation
  2. Mood disorders
  3. Social withdrawal
  4. Severe anxiety
  5. Sluggishness
  6. Disorganized thinking
  7. Bizarre behavior
  8. Suicidal ideations

Signs And Symptoms Of Schizophrenia

The symptoms of schizophrenia tend to vary in duration, intensity, and frequency—depending on the individual.

Experts 3 categorize the symptoms of schizophrenia into the following 3 groups:

1. Positive symptoms of schizophrenia

The positive symptoms of schizophrenia are those which are abnormally present. These mostly include

  • Hallucinations
  • Delusions
  • Disorganized speech
  • Disorganized behavior

2. Negative symptoms of schizophrenia

Negative symptoms associated with schizophrenia generally include

  • Flattened affect
  • Lack of interest in previously pleasurable activities
  • Reduced speech
  • Lack of initiative
  • Reduced energy

3. Cognitive symptoms of schizophrenia

The common cognitive symptoms of schizophrenia include

  • Irritability and a lack of concentration
  • Memory problems (like amnesia)
  • Difficulty in planning and structuring activities
  • Difficulty in processing information & making decisions
  • Lack of insight
  • Volatile behavior (related to anger and violence)

Types Of Schizophrenia

The common types 4 of schizophrenia include:

1. Paranoid schizophrenia

This type is characterized by positive symptoms of schizophrenia—involving repeated frequent visual or auditory hallucinations and one or more delusions.

2. Disorganized schizophrenia

Also known as Hebephrenia, this subtype is marked by disorganized speech and behavior. It may also involve impairment in the emotional expression or reactions of the patient. Although hallucinations and delusions may occur, they are not very prominent.

3. Catatonic schizophrenia

Catatonic schizophrenia is characterized by noticeable abnormal motor behavior. This may involve a substantial decrease in voluntary movement or agitation and hyperactivity. Motor behavior in this type of schizophrenia can range from stupor (extreme immobility) to waxy flexibility.

4. Undifferentiated schizophrenia

This type of schizophrenia is characterized by vague symptoms. The patient may behave in ways that can be seen in two or more of the other subtypes of schizophrenia. This can involve symptoms like hallucinations, delusions, paranoia, catatonic behavior, and disorganized speech or behavior.

5. Residual schizophrenia

This subtype is often considered the ‘recovery phase’ in which severe symptoms usually begin to fade. Residual schizophrenia occurs when a person, previously affected by at least one schizoid episode, has reduced or no symptoms; however, the person may still feel paranoid or have strange beliefs, or may be socially withdrawn.

What Causes Schizophrenia?

Schizophrenia causes are multiple, covering a wide range of genetic and environmental factors. These include:

1. Genetic factors

Genetics plays a vital role in the onset of schizoaffective disorders. People with a history of schizophrenia or other mental disorders (like depression, psychosis, bipolar disorders, etc.) are at a greater risk of schizophrenia.

However, no single gene has yet been identified and this makes genetic information unreliable when anticipating if someone may develop the disorder.

Research 5 shows that structural and functional changes in the brain can make a person vulnerable to schizophrenia. These include:

  • Changes in certain brain regions (like the hippocampus, parahippocampal gyrus, amygdala, etc.)
  • Dysfunctional neurotransmitters (like dopamine and serotonin abnormalities)
  • Viral and bacterial infections
  • Traumatic brain injury

3. Environmental factors

Common psychosocial factors associated with schizophrenia include:

  • Poverty
  • Stressful surroundings
  • Exposure to toxins
  • Unhealthy lifestyle
  • Experiences of trauma
  • Negative developmental experiences (like grief, war, invasion, terrorism, etc.)
  • A family history of mental disorders (like substance use disorders, psychosis, etc.)

Schizophrenia Diagnosis

According to the Diagnostic and Statistical Manual for Mental Disorders (DSM- 5 6), schizophrenia can be diagnosed if a person has been suffering from at least two of the following for a period of one month or more:

  1. Delusions
  2. Hallucinations
  3. Disorganization in speech
  4. Disorganization in behavior (catatonic stupor/ waxy flexibility)
  5. Decreased activity and emotional expression

The symptoms must result in significant distress and impairment in functioning. Moreover, they should not be a result of other mental illnesses or substance use.

A mental health professional arrives at a diagnosis after a careful examination of the symptoms and past history of the individual. Certain assessments such as the Positive and Negative Symptoms Scale (PANSS) and Clinical Global Impression Schizophrenia (CGI-SCH) may also be used to confirm the diagnosis 7.

Treatment For Schizophrenia

Schizophrenia may have a life-long prevalence and, if left untreated, can negatively impact your personal, professional, and social life. But, the lack of a definitive schizophrenia treatment regime, the ambiguity 8 surrounding schizophrenia diagnosis, and the stigmatization of schizoid patients act as impediments to timely and proper treatment.

The best and most effective treatment for this condition includes a long-term combination 9 of psychological interventions, medications, self-help strategies, and social support.

However, severe cases of schizophrenia heavily involve constant medical supervision and, even, hospitalization. If you or a loved one appear to suffer from the signs and symptoms of schizophrenia, it is important that you seek medical help immediately.

Myths About Schizophrenia

Schizophrenia is the subject of never-ending fascination, works of pop culture, and urban legends. Most schizophrenia cases have witnessed extreme media frenzy and stereotypical representations and, over the years, have accumulated a substantial body of myths and false, exaggerated notions.

Some of the most common myths 10 about schizophrenia include:

1. Schizophrenia is synonymous with a “split personality” or multiple personalities.

Schizophrenia is a separate psychiatric disorder from dissociative identity disorder or multiple personality disorder.

2. Schizophrenia is a rare condition.

Schizophrenia is not a rare condition. It affects 0.32% 11 of the global population worldwide.

3. People with schizophrenia are dangerous.

It is a huge misconception that people with schizophrenia are violent or dangerous. They are similar to healthy people and not every schizophrenic person requires restraint or hospitalization.

4. People with schizophrenia can’t be helped.

People with schizophrenia can lead happier, healthier lives if they avail of timely treatment 12. Schizophrenia can be effectively managed by therapy, medication, and social support.

5. Bad parenting is a cause of schizophrenia.

It is a misconception that bad parenting, especially that of female guardians, is a contributing factor to schizophrenia. Children without positive parenting are at risk of their own personal troubles and behavioral problems (like depression and aggression). This results in ongoing patterns of negative behavior and mental disorders like schizophrenia.

6. If a parent has schizophrenia, the child will get it too.

Schizophrenia is heritable, via genetics and psychosocial environment. Having a parent increases the risk of developing the disorder, but it does not necessarily mean that it is a sure causal factor.

7. People with schizophrenia aren’t smart.

People use stereotypes when talking about schizophrenia. Even though this mental health condition severely impacts cognitive and behavioral functioning, it does not restrict intellect or reasoning.

8. If you have schizophrenia, you require hospitalization.

Only severe cases of schizophrenia entail hospitalization or in-patient medical treatment.

9. Schizophrenia makes people lazy.

People with schizophrenia are widely stigmatized and their professional capacities are frequently questioned. Like any other debilitating mental illness, schizophrenia has its challenges but it doesn’t make people lazy. In fact, several famous and accomplished people are living with the disorder and thriving—with proper treatment.

10. Schizophrenia comes with a sudden psychotic break.

Schizophrenia is characterized by psychotic episodes, but it is very different from brief psychotic disorder or drug-induced acute and transient psychotic states.
