Among the various types of schizophrenia, the cure rate for paranoid schizophrenia, is relatively good. It is now accepted that there are 3 1/3, 1/3 patients have relatively good outcomes and are basically able to achieve clinical cure; 1/3 patients make significant progress but do not achieve clinical cure; 1/3 patients have poor outcomes and poor prognosis due to various factors. Other factors can also affect the prognosis of patients, such as the earlier the age of onset, the worse the prognosis of patients; the prognosis of patients with positive family history is worse; the prognosis of patients with longer disease duration is worse; the prognosis of patients with withdrawn and introverted personality and schizophrenic features before the disease is worse; the prognosis of patients with morphological changes such as brain atrophy is worse; the prognosis of patients with poor family and social support is worse; the prognosis of patients with slow onset is worse; the prognosis of patients with poor compliance with treatment is worse; the prognosis of patients with poor compliance with treatment is worse. The prognosis is poorer for patients with a slow onset; poor compliance with treatment; and poorer prognosis for patients with no obvious precipitating factors before onset. In contrast, there are individual differences and exceptions in the treatment of schizophrenia, so clinical reference is only made to the impact of onset factors on prognosis.
