Schizophrenia is a disease of the mind that is usually degenerative in nature. The complex disorder is generally characterized by symptoms, such as delusions, hallucinations (both auditory and visual) and disturbances in speech and is usually chronic in nature. The symptoms are not regular and can appear at any point of time. So it is highly possible that a person suffering from schizophrenia may sometimes bear resemblance to any other normal person and all of a sudden, might exhibit symptoms typical of Schizophrenia.

The causes of Schizophrenia include:

Brain Dysfunction: Abnormalities in the cerebral cortex (the cerebrum s outer covering that is vital in regulating consciousness) of the brain is the most common cause of this disorder. This is due to the presence of abnormally enlarged ventricles in that region. The decreased brain size owing to the enlarged ventricles is often related to the hallucinations and delusions experienced by schizophrenics.
Genetic Factors: Studies have also stated  genetics  to be an important cause behind this disorder. Closer the family ties, higher the risks of transmitting the disorder.
Biochemical Factors: More than one neurotransmitter is being targeted by recent drugs to control schizophrenia.

Symptoms which most people do not experience normally, but are found in people diagnosed with schizophrenia are said to be positive symptoms. They are:

Hallucinations: These are sensory experiences of things that do not exist outside the mind. Hallucinations usually manifest in the form of auditory or visual images.
Delusions: Delusions on the other hand are false beliefs one has about oneself. Delusions are of 3 major types:
Grandeur: Wherein the person imagines himself to be a famous personality
Persecution: The belief that somebody somewhere is plotting against you and the whole world is going to get you.
Control: The belief that a larger force, let s say a witch, a demon or even a duck for that matter is controlling your actions.
These positive symptoms generally respond well to medications.
In addition to this, schizophrenics think and speak differently than the rest of the society. They jump from idea to idea, lose track of speech mid-way and often speak in fragmented and haphazardly joined sentences. They are, in fact, unable to fix their attention on anything in particular.
Examples of the most common negative symptoms include:

The flat effect: The individual basically shows no facial expression and always has a flat emotionless mask on while staring into space. At times, they have inappropriate reactions to situations. Example - they might laugh at somebody's death and cry ad get angry when something good happens. 
Avolition: This condition occurs when the individual just sit for hours doing nothing as well as behaves in a way lacking any motivation or enthusiasm.

Schizophrenia -  Can Biochemical Factors be the Cause Behind it?

What is schizophrenia?
We all know it as a debilitating mental illness that plagues people across the globe. Schizophrenic patients often feel like they are being overtaken by situations and events that are beyond their control. They may complain of seeing people who are not there or hearing voices where there are none. This happens because the neurotransmitters in the brain of the patient do not function appropriately. There are various types, causes and symptoms of this disease. Read up to know more.

Symptoms: psychotic symptoms like delusion are common in patients suffering from this disease. Also, the patient may be severely blunted in the emotional sense, and may bear a lost look and wear a feeling of loss or absence at all times. The thought process or cognition of the patient may also suffer in such cases. Poor concentration and lack of coordination are some symptoms of this kind of suffering. Hallucinations and distorted thought processes also characterise the patient to a great extent. The patient may also display certain typical symptoms like social withdrawal, extreme apathy, and lack of motivation. The patient will also be in an emotionally numb state once the delusions have lessened.

Causes: so what causes schizophrenia, really? while no tests or conclusive examinations exist to pin point the exact diagnosis or cause of the disease, there are many factors that can contribute to the development and progression of the same. Hereditary factors play up in many cases while chemical imbalances in the brain also lead to this condition. The serotonin levels and the functioning of the neurotransmitters are the most significant causes of this disease, in such cases. Excessive abuse of drugs like lsd and cannabis can also contribute to this condition, while family relations and a dysfunctional environment can also lead to this disease.

Types: there are many different kinds of schizophrenia. One of them is paranoid schizophrenia, which makes the patient highly suspicious. Disorganised schizophrenia can lead to incoherence in speech and thought. Catatonic schizophrenia can cause social withdrawal while residual schizophrenia can lead to a complete lack of motivation. Finally, schizoaffective disorder can lead to major mood swings.

The various kinds of schizophrenia are characterised by varying degrees of mood swings, depression, paranoia and delusional thinking. The progression of the disease can be checked with the help of cognitive behavioural therapy, which can help in reprogramming the brain of the patient to a great degree. Rehabilitation programs as well as case management can help in the long run. But the key here is to recognise the symptoms early on and get the treatment or counselling started to reduce the symptoms and their spread.

Schizophrenia: Types, Causes and Symptoms

Schizophrenia is a severe, chronic mental disorder that affects an individual s ability to think and make decisions, as well as relationships and emotions. The illness is characterized by experiences or unrealistic thoughts, disorganized behaviour and speech, reduced participation in routine activities. A person diagnosed with schizophrenia also experiences difficulty concentrating and memorizing things.

Schizophrenia does not have a definite cure. However, psychological rehabilitation can help the patient manage the symptoms of the illness, and improve the quality of life. This is where psychosocial therapy steps in.

Rehabilitation Psychology for Schizophrenia

Rehabilitation Psychology is a speciality of Psychology that utilizes psychological skills, knowledge, and theories to evaluate and treat people diagnosed with disabilities and chronic health issues in order to maximize functional ability, independence, social participation, and overall health.

A rehabilitation psychologist individualizes services to address different patients with varying health conditions. In order to meet this goal, the discipline adopts a holistic approach and considers individuals within a broad social context.

Different Treatment Approaches

Rehabilitation psychology follows these techniques to address mental disorder like schizophrenia in people  

Individual Psychotherapy   a psychologist/therapist teaches the patient how to deal with their behaviours and thoughts. Patients learn more about the ailment and its effects   and how to distinguish between what is real and what is not. The therapy may also help them manage day-to-day life.

Cognitive Behaviour Therapy   CBT can help the patient change the way they think or behave. A psychologist can show them how to deal with hallucinations and voices. After a couple of CBT sessions, you may be able to identify what triggers psychotic episodes   delusions and hallucinations   and prevent or reduce them.

Cognitive Enhancement Therapy   CET teaches individual ways to recognize triggers, social cues better, and improve memory and attention, and the ability to organize thoughts. The therapy combines group sessions and computer-based brain training.

Social Skills Training aimed towards improving social interactions and communication
Rehabilitation procedures such as problem-solving support and job counselling

Even if the above techniques are able to improve the condition, a schizophrenic person will likely need to continue with special care and education on how to become part of the community. 




How Effective Is Rehabilitation Psychology In Managing Schizophrenia?

Neurological disorders are an enigmatic bunch. There are various ongoing researches to identify the exact cause and how to treat them. While some argue that schizophrenia is a chronic brain disorder, others do not agree with it and debate that the origin is yet to be identified and the factors which produce it are yet to be identified.

Factors supporting it to be a brain disease are listed below.

Scan images (MRI and PET scans) of people who have had schizophrenia are different and have a reduced volume of grey matter, especially in the frontal and temporal lobes. In some people, this loss could be as high as 25%. Serial images have shown that the loss begins in the outer (parietal) region and gradually spreads to the rest of the brain. There is a strong correlation between the extent of this grey matter loss and the severity of the symptoms more the loss, worse the symptoms. Severe symptoms include hearing voices, psychotic thoughts, delusions, hallucinations and severe depression. This grey matter reduction does not depend on whether the person has undergone treatment or not for the condition. 

The counter argument is that grey matter loss is not seen in patients with schizophrenia alone. A number of neurological disorders, including normal ageing, manifest as grey matter loss on the scan images. Also, another consoling news is that this grey matter loss is completely reversible.

The way neurotransmitters respond to stimuli in people with schizophrenia is also slightly different. There are two variations to this debate: that schizophrenia is caused by excessive amounts of dopamine or increased sensitivity to dopamine. There are two proofs for this hypothesis first, dopamine suppressants are useful as antipsychotic drugs and secondly drugs which produce the same effect as dopamine can cause hallucinations similar to those seen in schizophrenics. There could be other neurotransmitters involved too, but the dopamine connection is more strongly established.

The electrical activity of the brain as seen in EEG is very different and abnormal in schizophrenic people. This reduced brain activity is another indication of the fact that schizophrenia is another brain disorder. There is also a strong genetic component to schizophrenia. Family history correlation is also very strong. The correlation extends to the point that where there is a neurologic disorder in the first-degree relatives, the chances of developing schizophrenia is increased.

There are specific genes, mutations of which are also attributed to schizophrenia. While the risk factors are in place (as mentioned above), the environmental conditions (brain infections, head trauma, family/social stressors and toxins can all lead to the manifestation of the symptoms. With medications and support therapy, both prevention and symptom management are possible.

Schizophrenia - Is It Really a Brain Disease?

Schizophrenia is a psychiatric disorder in which a person s mood, knowledge, thought and several other characteristics gets disturbed. We can notice most of the adults and old people with few symptoms of schizophrenia, which are most commonly left unidentified. The exact cause of schizophrenia is not yet known. The person feels that they are being constantly watched, they feel the presence of someone or something, which is not actually there. They are always suspicious and think that other people are gossiping and thinking about them.

Possible causes of Schizophrenia
Though the exact cause of schizophrenia is not known there are few factors, which contribute to the cause of schizophrenia.

    Genetic factors: People with a family history of schizophrenia are at higher risk of getting schizophrenia.
    Environmental factors: Environmental factors include excessive stress during pregnancy or later stages of life. Several other factors during pregnancy and childhood are responsible for causing schizophrenia. These factors are:
        Decreased oxygen level during delivery due to premature birth or prolonged labour
        Parental loss or separation in early stages of life
        Parental exposure to virus or during infancy
        Childhood physical or sexual abuse
        Abnormal brain structures and brain chemistry

Sings and symptoms of schizophrenia

    Hallucination: To see, feel or hear anything that really does not exist is known as hallucination.
    Delusion: A thought or belief of a person, which is either false or impossible in reality is known as delusion.
    Thought and speech disturbances: The thought process and speech of a schizophrenic will be disorganized, due to which he or she  will fumble or is distracted as they are unable to align their thoughts.
    Difficulty in concentrating: It is difficult for people suffering from schizophrenia to concentrate on the task at hand.
    Erratic behaviour: People suffering from schizophrenia tend to behave erratically, either they will be too jumpy or will be perfectly still for hours at a stretch. Most people belief that those who are suffering from schizophrenia are often violent in nature, which actually is not the case.

Treatment for schizophrenia
Schizophrenia can be treated, if identified at an early stage. . It is best advised to consult a psychiatrist the moment you spot the symptoms. Anti psychotic drugs, self help behaviour change, counselling and rehabilitation are few treatment modalities available for schizophrenia.

Schizophrenia: Can Genetics be the Reason Behind it?

Schizophrenia has been recognized as a mental disorder that combines symptoms like hallucinations with distorted thinking and others like fright and severe paranoia. This condition is one that gets progressively worse over time and leads to delusional thinking. Oversleeping and complaining of fatigue are usually the earliest signs of this condition's onset. Eventually, it becomes a debilitating factor in the life of the patient, who will not be able to function in a normal way due to the severe symptoms.

Read on to know more about the types and causes of this condition:

Genetic Causes: Schizophrenia may be caused due to genetic factors and it may be a learned or inherited disorder. It is known to affect patients who have a parent or a sibling who may have suffered from this condition. Yet, one must also remember that Schizophrenia can only be influenced by genetics, and not determined by the same.
Environmental Causes: When there has been an exposure to a viral infection during the pre natal stage, the patient is susceptible to this condition. Also, it may affect children who have been subject to the loss of a parent or separation at an early age. Physical and emotional abuse in one's childhood may also bring on this condition. Low level of oxygen at the time of birth is one of the causes of this condition in many patients.
Anomalies in Brain Structure: When the brain ventricles of the patient are enlarged, he or she may be prone to this condition. Also, anomalies in the temporal lobes and amygdala have links with the onset of this condition.
Types: A wide variety of mental and medical conditions can manifest with psychotic symptoms that must be considered in the differential diagnosis of schizophreniform disorder. These include psychotic disorder due to another medical condition or its treatment; delirium or major neurocognitive disorder; substance/medication-induced psychotic disorder or delirium; depressive or bipolar disorder with psychotic features; schizoaffective disorder; other specified or unspecified bipolar and related disorder; depressive or bipolar disorder with catatonic features; schizophrenia; brief psychotic disorder; delusional disorder; other specified or unspecified schizophrenia spectrum and other psychotic disorder; schizotypal, schizoid, or paranoid personality disorders; autism spectrum disorder; disorders presenting in childhood with disorganized speech; attention-deficit/hyperactivity disorder; obsessive-compulsive disorder; posttraumatic stress disorder; and traumatic brain injury.
Since the diagnostic criteria for schizophreniform disorder and schizophrenia differ primarily in duration of illness, the discussion of the differential diagnosis of schizophrenia also applies to schizophreniform disorder. 

Brief psychotic disorder. Schizophreniform disorder differs in duration from brief psychotic disorder, which has a duration of less than 1 month.

Residual Schizophrenia is a condition where the patient does not experience the various debilitating symptoms of the condition, and is on the road to recovery. Yet, even in this type of Schizophrenia, the patient will not really show any interest in life and the activities around him or her. Finally, the last type of Schizophrenia is Schizoaffective Disorder which is characterised by the symptoms of Schizophrenia as well as the symptoms of major mood disorders. When combined, this condition can lead to major complications and complex behavior.

A patient suffering from this condition will need to see a mental health specialist like a psychiatrist or a psychologist on an immediate basis. The treatment will be carried out on a long term basis for the results to start appearing.
