Schizophrenia is a mental disorder which is characterized by disturbed mental thoughts in the patient, paranoia, phobias, hallucination, slow dementia and etc. As it is clear from this brief definition, Schizophrenia is a serious mental illness which can leave a patient stranded from performing basic day-to-day activities or even keeping healthy relationships with their close ones. 

Even though there is no particular age where people are vulnerable from suffering from this disease, yet from a common observation and study conducted on the patients, it has been observed that schizophrenia hit men in their early 20 s and early 30 s in case of women. The study also feels that it is impossible for a schizophrenic to be of age younger than 12 or older than 40. According to another study conducted by the universities, the life of a schizophrenic patient is not guaranteed. 

Symptoms of Schizophrenia:

As mentioned above, there is a common pattern in each schizophrenic patient, however, it is next to impossible to diagnose schizophrenia in teenagers since the onset of the disease is symbolized by the patient's constant change of friends or decrease of performance in school, both of which is normal in teen years. Schizophrenics also isolate themselves and become moody which again, is a common instinct of the teenager. However, apart from these, there are other differentiating symptoms as mentioned below which help in the accurate diagnosis of the disease. 

Hallucinating
Delusional
Emotionally dull and disconnected with their loved ones
Negative social life and academic performance
Dementia
Disability of remembering easy-to-learn and remember things
Causes of Schizophrnia

According to the researchers, there are more than one reasons for this disease. Read them all below:

Genetic mutation and inheritance- genetics play an important role in this disease. It needs more than one mutational combination of schizophrenia to happen and that is why it is observed in less than 1% of the population only. Those who have had a family history of schizophrenia are very hard to inherit the disease because patients hardly ever reach the stage of life called marriage. But a family history of psychosis is sure a determining factor. 
Neurotic reason- this reason includes the brain chemistry and important brain chemical such as- dopamine and glutamate.
Drug abuse- it has been revealed that consuming hallucinating and mind-altering drugs during teenage years are greatly responsible for the increase in the number of schizophrenia cases in early 20 s.
Treatment

As it was mentioned above, there is absolutely no way to cure schizophrenia known to man as of yet. However, the only way to approach it medically is by managing its symptoms separately. Such as:

Antipsychotic medication
Psychotherapies Self-help groups
Nursing care

Schizophrenia - What Causes 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

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 debilitating mental and emotional condition that is characterised by a heavily distorted thought process as well as hallucinations and even extreme fear that borders on paranoia. Let us find out more about this debilitating disease:

Causes:
1. Genetics: genetic factors play an important role in the development of schizophrenia.
2. Environment: possible environmental factors include obstetric complications, the mother's exposure to influenza during pregnancy or starvation. It has also been suggested that stress, trauma even migration can lead to the emergence of schizophrenia. 
3. Neurodevelopmental factors: schizophrenia appears to be a neurodevelopmental disorder. That is changes that cause the illness have been occurring from the earliest stages of development even in utero, and may continue to influence the development of the brain over the first 25 years of life. 

Symptoms: 
This disease has a variety of symptoms include cognitive and emotional ones that can vary in the degree and severity. One of the most common symptoms included hallucinations and delusions where the patient may end up imagining things that do not really exist. The patient may also be gripped by sudden and crippling fear like paranoia, which can be debilitating as far as everyday functioning of the person goes. The symptoms can also interfere with the way a person deals with situations and life skills on a cognitive basis. Withdrawal and hopelessness are also a part of this disease.

Treatment: 
The earliest signs and symptoms must be referred to a psychiatrist. The treatment involves the management of the case of an individual basis along with psychological rehabilitation programs and inclusion of the patient in self-help groups. Housing and employment programs must also be availed so as to keep the patient busy. Also, behaviour therapy will be required in such cases. The mode of counselling should usually be on a one on one basis, although many doctors also suggest that group therapy can help in showing examples of progress so as to encourage the patient to change and get a new lease of life.

Schizophrenia: Causes, Symptoms and Treatment

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?

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.
