SCHIZOPHRENIA By: Sathish Rajamani Professor DSCON - CUTTACK Professor Sathish Rajamani 1
Overview of Schizophrenia In Greek word ‘ Schizein ’ – ‘To Split’ and ‘ Phren ’ – ‘Mind’ “Splitting of the Mind”. Schizophrenia is a serious mental illness that affects how a person thinks, feels, and behaves. People with schizophrenia may seem like they have lost touch with reality, which can be distressing for them and for their family and friends. People with schizophrenia require lifelong treatment.

Paul Eugen Bleuler Swiss psychiatrist He coined several psychiatric terms including S chizophrenia , S chizoid & A utism . Professor Sathish Rajamani 3
Definition A mental illness that is characterized by disturbances in thought (as delusions), perception (as hallucinations), and behavior (as disorganized speech or catatonic behavior), by a loss of emotional responsiveness and extreme apathy, and by noticeable deterioration in the level of functioning in everyday life. Professor Sathish Rajamani 4
EPIDEMIOLOGY OF SCHIZOPHRENIA The usual age of onset for adult Schizophrenia is 15 to 25 years. C hildhood-onset schizophrenia (COS) is a rare condition with onset before the age of 13 years . According to a recent National Mental Health Survey (2015-2016) conducted by NIMHANS, the prevalence of Schizophrenia in the Indian population is 0.5 per cent for current and 1.4 per cent for a lifetime experience. According to a study on mental patients arriving at the Institute of Mental Health and Hospital in Agra, 7 per cent of all mental patients have schizophrenia in various degrees of severity. Professor Sathish Rajamani 5
EPIDEMIOLOGY OF SCHIZOPHRENIA Schizophrenia affects 20 million people worldwide. (Global Burden of Disease, 2017) The annual number of new cases of schizophrenia is 1.5 per 10,000 people. ( Epidemiol Reviews , 2008) Schizophrenia is one of the top 15 leading causes of disability worldwide. (Global Burden of Disease, 2016) Approximately 5% of people with schizophrenia die by suicide, usually with a higher risk at the onset of the mental illness. ( Archives of General Psychiatry, 2005) About 20% of people with schizophrenia attempt suicide at least once. (The Recovery Village, 2020) Professor Sathish Rajamani 6
Co-occurring disorders and schizophrenia Depressive symptoms: 30%-54% Post-traumatic stress disorder: 29% Obsessive-compulsive disorder: 23% Panic disorder: 15% (The Recovery Village, 2020) Professor Sathish Rajamani 7
Gender and Schizophrenia Females are affected around 30 years of age. Onset of Schizophrenia is earlier in males (around 20 years). In general males and females are equally affected with schizophrenia. Professor Sathish Rajamani 8
Aetiology of Schizophrenia The exact causes of schizophrenia are unknown . Research suggests a combination of physical, genetic, psychological and environmental factors can make a person more likely to develop the condition. 1. Genetics: Schizophrenia tends to run in families, but no single gene is thought to be responsible. Professor Sathish Rajamani 9
Aetiology of Schizophrenia Genetics ( Cont ) In identical twins, if a twin develops schizophrenia, the other twin has a 1 in 2 chance of developing it, too. This is true even if they're raised separately. In non-identical twins, who have different genetic make-ups, when a twin develops schizophrenia, the other only has a 1 in 8 chance of developing the condition. Professor Sathish Rajamani 10
Aetiology of Schizophrenia 2. Brain Structure and Function: Research shows that people with schizophrenia may be more likely to have differences in the size of certain brain areas and in connections between brain areas. Professor Sathish Rajamani 11
Aetiology of Schizophrenia 3 . Neurotransmitter: There's a connection between neurotransmitters and schizophrenia because drugs that alter the levels of neurotransmitters in the brain are known to relieve some of the symptoms of schizophrenia. Research suggests schizophrenia may be caused by a change in the level of 2 neurotransmitters: dopamine and serotonin. Professor Sathish Rajamani 12
Aetiology of Schizophrenia 5. Pregnancy and Birth Complications: Research has shown people who develop schizophrenia are more likely to have experienced complications before and during their birth, such as: a low birthweight premature labour a lack of oxygen (asphyxia) during birth It may be that these things have a subtle effect on brain development. Professor Sathish Rajamani 13
Aetiology of Schizophrenia 4 . Environment: Research suggests that a combination of genetic factors and aspects of a person’s environment and life experiences may play a role in the development of schizophrenia. These environmental factors that may include living in poverty, stressful or dangerous surroundings, and exposure to viruses or nutritional problems before birth. Professor Sathish Rajamani 14

Eugen Bleuler’s 4 ‘A’s of Schizophrenia Ambivalence Autistic Thinking Affect Disturbances Association Disturbances Professor Sathish Rajamani 22
Eugen Bleuler’s 4 ‘A’s of Schizophrenia Ambivalence – It is the state of having the mixed feelings or contradictory ideas . Autistic Thinking – Thinking is directed inward and become subjective, leads to withdrawal in self, daydreaming and fantasies.

PARANOID SCHIZOPHRENIA Most common type Onset is late and has good prognosis Client’s can perform ADL and have good social interactions Hallucination and Delusions are seen peculiarly With earlier treatment, good prognosis is seen. Delusion of persecution Delusion of reference Delusion of jealousy Delusion of grandiosity Professor Sathish Rajamani 25

CATATONIC SCHIZOPHRENIA Catatonia is a motor disorder that impairs a person’s movement, speech and response to an outside stimuli. Cata means disturbed. When excited patient will injure themselves or others Patients are sometimes immobile and mute Increased Physical activity (Hyperkinesis) or decreased (Stupor) Professor Sathish Rajamani 27
CATATONIC SCHIZOPHRENIA TYPES Professor Sathish Rajamani 28
Professor Sathish Rajamani 29
SIMPLE SCHIZOPHRENIA Characterized by prominent negative symptoms Positive symptoms are absent Social functioning gets reduced Onset is early and insidious Course is progressive and prognosis is worst Amotivation Apathy Social Withdrawal Blunt Affect Professor Sathish Rajamani 30
RESIDUAL SCHIZOPHRENIA A subtype of schizophrenia in which the individual has suffered an episode of schizophrenia but there are no longer any delusions, hallucinations, disorganized speech or behavior . Professor Sathish Rajamani 31
UNDIFFERENTIATED SCHIZOPHRENIA Undifferentiated schizophrenia is an outdated term describing a subtype of schizophrenia that the medical community no longer recognizes. It cannot be classified into any of the five defined subtypes. People who are diagnosed with undifferentiated schizophrenia exhibit symptoms of more than one type of schizophrenia.
