Schizophrenia is a mental illness characterized by the breakdown of thought processes and emotional disorders. This disease is characterized by a combination of disorders: cognitive (impaired attention, memory, thinking) and behavioral, productive (hallucinatory, delusional, affective, etc.) and negative (apathy, abulia, emotional and social detachment, etc.) symptoms. Schizophrenia causes psychosis, can be accompanied by disability and negatively affect all areas of life, including personal, social life, family and work activities. This disease is also characterized by changes in emotions, loss of concentration, autism, asociality ("immersion in oneself", unusual thoughts and fantasies), a drop in energy state and a violation of the will. The sick person does not understand that he is ill, and this complicates treatment. Psychoses become more frequent over time and this leads to frequent hallucinations, and they can affect all the senses. The most common are auditory hallucinations in the form of voices and a person's subordination to voices, which can make the situation dangerous. The absence of treatment for schizophrenia leads to an absolute loss of one's own "I", loss of a person's personality, and during an exacerbation of the disease, a person can harm first of all himself and then others. The following research article examines all the factors that can influence the onset and progression of the disease.
