SCHIZOPHRENIA -By Eesha Madan 1) Key facts: 1.1 Schizophrenia does not involve split personalities. 1.2 Symptoms of schizophrenia usually emerge in adolescence. 1.3 Schizophrenia has both genetic and environmental causes. 1.4 The only way to diagnose schizophrenia is through a combination of tests. 1.5 Schizophrenia causes psychosis and is associated with considerable disability, potentially affecting all areas of life including personal, family, social, educational, and occupational functioning. 2) What is “Schizophrenia”? Schizophrenia is a complex, chronic mental health disorder characterized by an array of symptoms, including delusions, hallucinations, disorganized speech or behavior, and impaired cognitive ability. In clinical settings, schizophrenia is ordinarily diagnosed through the observation of positive symptoms (delusions, hallucinations, disordered speech, and behavioral disturbances) and negative symptoms (a volition, alogia, and anhedonia). However, schizophrenia has considerable overlap with other neurological disorders (e.g., bipolar disorder, autism spectrum disorder, and Huntington’s disease) at both the clinical and genetic levels. The study of schizophrenia is important because it can help us understand the brain and mind, the biological nature of the disorder, and the severity of its symptoms 3) What are the symptoms of Schizophrenia The symptoms of schizophrenia can be divided into three categories: 3.1 Positive symptoms (i.e. excesses of thoughts, emotions & behaviour ) 3.2 Negative symptoms (i.e. deficits of thoughts, emotions & behaviour) 3.3 Psychomotor symptoms 3.1 Positive Symptoms: Positive symptoms of schizophrenia include hallucinations, delusions, and any changes in thoughts or behaviours. Positive symptoms are those that affect the individual’s thoughts or behaviours. They are pathological and bizarre additions to a person’s behaviour: delusions, disorganized thinking and speech. 3.1.1 Delusions : Delusions are fixed, false beliefs that conflict with reality. If a person is delusional, they can not let go of their untrue convictions despite contrary evidence. Types of delusions: Delusions of persecution: Most common in schizophrenia. People with this delusion believe they are being plotted against, spied on, slandered, threatened, attacked or deliberately victimized. Delusions of reference: In which they attach special and personal meaning to the actions of others. Delusions of grandeur: People believe themselves to be specially empowered persons. Delusions of control: They believe that their feelings, thoughts and actions are controlled by others. Erotomanic: Believing someone else is in love with you is an Erotomanic delusion. For example, an Erotomanic delusion might include thinking a celebrity loves you even when you’ve never met or corresponded. Nihilistic delusions: they get their name from the philosophical concept of nihilism, which suggests life has no fundamental meaning or purpose. Nihilistic delusions involve thoughts related to non-existence, like believing a major catastrophe will occur or that humanity is already in the afterlife. Somatic delusions: It involves a preoccupation with health and organ function. They can include irrational beliefs about how your body functions or inaccurate beliefs about how natural sensations predict illnesses—for example, attributing the typical sensation of hunger to progressive stomach cancer. Bizarre delusions: This includes any false belief that is completely implausible, isn’t derived from ordinary life experiences, and isn’t seated in cultural practices. 3.1.2 Formal thought disorder: People aren’t able to think logically and they may speak in peculiar ways, so this disorder can make communication extremely difficult. This includes rapidly jumping from one topic to another. So their normal structure of thinking is muddled and becomes illogical. 3.1.3 Hallucinations: A hallucination happens when you receive sensory information that doesn’t exist — it’s a disturbance in perception created by your brain. Types of hallucination : Auditory. The person most often hears voices in their head. They might be angry or urgent and demand that they do things. It can sound like one voice or many. They might whisper, murmur, or be angry and demanding. Visual. Someone might see lights, objects, people, or patterns. Often it’s loved ones or friends who are no longer alive. They may also have trouble with depth perception and distance. Olfactory and gustatory. This can include good and bad smells and tastes. Someone might believe they’re being poisoned and refuse to eat. Tactile. This creates a feeling of things moving on your body, such as hands or insects. Somatic. This includes the feeling and sensations of something happening inside the body. 3.1.4 Inappropriate Affect People with schizophrenia also show Inappropriate affect, i.e. showing or expressing emotions that are unsuited to the situation. For eg- laughing at your loved one’s funeral. 3.2 Negative Symptoms: Affective flattening: Impaired emotional expression 2. Alogia: decreased speech output Asociality: reduced desire to have social contact Avolition: reduced drive to initiate and persist in self-directed purposeful activities Anhedonia: decreased experience of pleasure Blunted affect: It includes showing emotions less for eg: less anger, sadness, joy and other feelings. Flat affect: This eludes showing no emotions at all. 3.3 Psychomotor Symptoms: Catatonic stupor: People who remain motionless and silent for long periods. Catatonic rigidity: It includes people who maintain rigid and upright postures for hours. Catatonic Posturing: In this people assume awkward and bizarre positions for long periods. 4) What causes Schizophrenia Medical researchers have not been able to find the exact causes of schizophrenia. Research now tells us that the disorder is linked to abnormalities in the structure of the brain. Some factors are believed to put a person at a greater risk of developing schizophrenia: Genetic factors: Having a parent or sibling with schizophrenia puts the person at increased risk A chemical imbalance in the brain Problems during pregnancy: The child may develop schizophrenia if the mother does not receive proper nutrition, or is exposed to viral illnesses
