Prognosis depends on the cause and the type of psychosis. Chronic conditions, like schizophrenia, need lifetime treatment. The main goal is to treat the symptoms as soon as possible so that the person can recover completely and prevent the gradual deterioration. Without treatment, prognosis is grim. Patients suffering from psychosis have impairments in different areas, such as their ability to relate to others, keep a job and in the most severe cases, even take care of themselves. Treatment is needed to help patients have the life they will be willing to have. However, in 30% of the patients, treatment shows to be ineffective, leading to more suffering for the patient and their family. This is why there are so many ongoing studies related to the topic, as there is still a lot of work to be done in the field of psychosis.
