Schizophrenia is a severe psychotic disorder that affects how a person thinks, feels and acts. Someone with schizophrenia may have difficulty distinguishing between the real and the imaginary can be apathetic and isolated from others, and may have difficulty expressing normal emotions in social situations.

Most people with schizophrenia are not violent and do not pose a danger to others. Schizophrenia is not caused by childhood experiences or neglectful parents, nor are the symptoms identical for each person.

Causes of Schizophrenia
The cause of schizophrenia remains unclear. There are genetic theories (inheritance), biological (biochemical imbalance in the brain), and possible viral infections and immune disorders.

Genetics (Heredity). Scientists recognize that the disorder tends to run in families and that a person inherits a tendency to develop the disease (but not this will necessarily come to develop). In predisposed individuals, schizophrenia can be triggered by environmental events, such as viral infections or highly stressful situations (eg, being raised in a dysfunctional and pathological) or a combination of both.

Similar to other diseases related to genetics, schizophrenia appears when the body undergoes hormonal and physical changes, such as those that occur during puberty and adolescence.

Biochemistry. People with schizophrenia have a chemical imbalance of certain chemicals in the brain (serotonin and dopamine) that are called neurotransmitters. These neurotransmitters allow neurons (brain cells) to send signals between them. The imbalance of these neurotransmitters that affect how a person’s brain reacts to stimuli, which explains why a person with schizophrenia may be overwhelmed by sensory information (loud music or bright lights) that most people can handle easily. This problem processing different sounds, smells, etc. May also lead to hallucinations or delusions.

The first signs of schizophrenia
The signs of schizophrenia are different for each person. Symptoms may develop slowly over months or years, or may appear suddenly. The disease courses in cycles of remission and relapse.
