Schizophrenia: What it is, Causes, Symptoms, Treatment & Types

What is Schizophrenia?

Schizophrenia is a chronic mental health disorder that affects how people think, feel, behave, and interpret reality. It can make it difficult to distinguish between what is real and what is not, leading to symptoms such as hallucinations, delusions, disorganised thinking, and changes in behaviour.

The severity and type of symptoms vary from person to person. Even though schizophrenia is a lifelong disorder, many people are still able to manage their symptoms and lead fulfilling lives with early diagnosis, proper treatment, and ongoing support.

How Common is Schizophrenia in India?

According to WHO, schizophrenia occurs in 1 out of 345 individuals or 0.29% of the population in the world. Although India-specific prevalence varies across studies, given India's large population, millions of people are estimated to be living with schizophrenia. The condition most often begins during late adolescence or early adulthood, with symptoms usually appearing earlier in men than in women.

What are the Symptoms of Schizophrenia?

Symptoms of schizophrenia often appear in the late teens to early 20s in men and the late 20s to early 30s in women. However, the pattern and severity of symptoms differ from person to person.

• Hallucinations: Perception of sights, sounds, smells, tastes, or sensations that do not really exist. Hearing voices is the most common type, and these experiences feel real to the person.

• Delusions: Delusions are false beliefs that an individual strongly believes even when there is no evidence to support them. They may think someone is trying to harm or control them, or believe they have special powers or importance.

• Disorganised or Abnormal Behaviour: A person may behave in unusual or unpredictable ways and have trouble completing everyday tasks or responding appropriately in different situations. In some cases, they may become extremely restless or unusually inactive.

• Disorganised Thinking and Speech: Schizophrenia can make it difficult to think clearly and organise thoughts. This may make speech confusing, with answers that are unrelated or difficult to understand.

• Negative Symptoms: Negative symptoms involve a decrease in normal emotions and behaviours. A person may show little emotion, lose interest in daily activities, avoid social interactions, speak less, or have difficulty staying motivated.

What Causes Schizophrenia?

The exact cause of schizophrenia is not completely understood. However, experts believe that it develops due to a combination of biological, genetic, and environmental factors rather than a single cause.

• Genetics: A family history of schizophrenia can increase the risk, although many people with the condition have no affected relatives.

• Brain Chemistry and Structure: Imbalances in brain chemicals, like dopamine and glutamate, and differences in brain development or structure may contribute to schizophrenia.

• Pregnancy and Birth-related Factors: Certain complications during pregnancy or birth, such as poor nutrition, infections, or lack of oxygen during delivery, might increase the risk.

• Environmental Factors: Difficult life experiences, abuse in childhood, being lonely, or being infected with certain viruses while growing up might lead to symptoms in vulnerable people.

• Substance Use: The use of cannabis and some other psychoactive drugs, especially during adolescence, may increase the chances of developing schizophrenia in susceptible individuals.

What are the Complications of Schizophrenia?

If left untreated or poorly managed, schizophrenia can affect many aspects of a person's life. Common complications include:

• Difficulty with Daily Activities: Trouble managing daily activities, including personal care, household tasks, education, or work.

• Relationship Problems: Social withdrawal and communication difficulties can affect relationships with family, friends, and colleagues.

• Anxiety and Depression: Many people with schizophrenia also experience anxiety, depression, or other mental health conditions.

• Substance Misuse: Some individuals may misuse alcohol or drugs, which can worsen symptoms and make treatment less effective.

• Physical Health Problems: People with schizophrenia have a higher risk of problems, such as obesity, heart disease, diabetes, and poor overall health.

• Self-harm and Suicide Risk: Schizophrenia is associated with a risk of self-harm and suicidal thoughts or behaviours, particularly if symptoms are severe or untreated.

When Should I See My Healthcare Provider?

You should seek medical advice if you or someone you know experiences any of the following:

• Persistent Hallucinations or Delusions: Seeing, hearing, or strongly believing things that are not real.

• Changes in Thinking or Behaviour: Confused thinking, unusual behaviour, or difficulty communicating.

• Social Withdrawal: Avoiding family, friends, work, or school for an extended period.

• Difficulty Managing Daily Activities: Struggling with personal hygiene, routine tasks, or responsibilities.

• Severe Mood or Emotional Changes: Showing little emotion, losing interest in usual activities, or experiencing significant emotional distress.

• Thoughts of Self-harm or Suicide: Seek quick medical attention or emergency care if there are any thoughts of self-harm or suicide.

How is Schizophrenia Diagnosed?

There is no single test that can diagnose schizophrenia. A healthcare provider diagnoses a person by evaluating their symptoms, medical history, and mental health. They may also perform tests to rule out other conditions that can cause similar symptoms.

The diagnostic process may include:

• Medical and Psychiatric Evaluation: The doctor asks about symptoms, personal and family medical history, and any changes in thoughts, emotions, or behaviour.

• Physical Examination: A physical examination may be done to identify underlying health issues contributing to the symptoms.

• Laboratory Tests: Blood tests or other investigations might be recommended to rule out infections, hormonal disorders, substance use, or other medical conditions.

• Mental Status Examination: The healthcare provider assesses thinking, mood, memory, behaviour, speech, and perception.

How is Schizophrenia Managed?

Schizophrenia is a lifelong problem, but it can be managed with the appropriate treatment and ongoing support.

• Medications: Antipsychotic medications are used as the principal treatment and help control such symptoms as hallucinations and delusions.

• Psychotherapy: Psychological treatments, such as Cognitive Behavioural Therapy (CBT), may help one cope with symptoms and stress and improve the quality of life.

• Psychosocial Support: Social skills training, vocational rehabilitation, family education, and community support programmes can help improve independence and quality of life.

• Lifestyle Changes: Eating healthy, exercising, ensuring adequate sleep, staying away from alcohol, and dealing with stress may contribute to general well-being.

• Regular Follow-up: Ongoing appointments with a mental healthcare professional help monitor symptoms, adjust treatment when needed, and reduce the risk of relapse.

• Hospitalisation: In severe cases, short-term hospital care may be required to ensure safety, stabilise symptoms, and provide intensive treatment.

What is the Prognosis for Schizophrenia?

The prognosis for schizophrenia varies from person to person and depends on factors such as the severity of symptoms, how early treatment begins, and how well the individual responds to therapy. Although schizophrenia is a lifelong condition, many people are able to manage their symptoms effectively with a combination of medication, psychological therapy, and ongoing support.

An early diagnosis, proper medication, and an effective support network can help prevent relapse, improve functioning, and increase one’s quality of life. While some people experience occasional episodes of symptoms, others achieve long periods of stability and are able to work, study, maintain relationships, and live independently.

How Can I Prevent Schizophrenia?

There is no proven way that can prevent schizophrenia because its exact cause is not fully understood. However, certain healthy lifestyle choices and early intervention may help reduce the risk of developing symptoms or prevent them from becoming more severe.

Avoiding recreational drugs, such as marijuana and other psychoactive drugs, effective stress management, sleeping regularly, and visiting a doctor immediately if there have been noticeable changes in thoughts, behaviour, and emotions may prove helpful. For people with schizophrenia, following the prescribed treatment plan and attending regular follow-up appointments can help reduce the risk of relapse and improve long-term outcomes.

Does Health Insurance Cover Schizophrenia?

Yes, most of the health insurance policies offered in India offer coverage for the treatment of schizophrenia. Depending on the terms of the policy, coverage may include hospitalisation, psychiatric consultations, prescribed medications, diagnostic tests, and other medically necessary treatments. Some policies even cover day-care treatments as well as pre and post-hospitalisation costs. However, the extent of coverage, waiting periods, exclusions, and claim limits can vary between insurers.

It is important to read your policy documents carefully or speak with your insurance provider to understand the benefits and limitations of your specific health insurance plan.

How Much Health Insurance Coverage is Needed for Schizophrenia Treatment?

The amount of health insurance coverage that would suffice for treatment of schizophrenia would depend upon various factors, such as severity of the illness, kind of treatment required, and need for multiple admissions into hospitals. Generally, an adequate health insurance cover of ₹5 lakh to ₹10 lakh would be sufficient to meet all expenses.

If a person has other medical conditions or prefers treatment at private hospitals with higher costs, choosing a higher sum insured may provide better financial protection.
