Causes of Schizophrenia

Schizophrenia is a clinical syndrome made up of a group of symptoms. It is a multifactorial disease. Although the current understanding of its etiology is still not clear, the role of individual psychological susceptibility and external social environment factors in the occurrence and development of the disease has been widely recognized. Both susceptible quality and external adverse factors may cause the occurrence of diseases through the combined effects of internal biological factors. The pathogenesis of different patients may be more important in some aspects.

Clinical manifestations of schizophrenia

Clinical manifestation

The clinical symptoms of schizophrenia are complex and diverse, and can involve perception, thinking, emotion, will behavior, and cognitive functions. Symptoms vary greatly from individual to individual. Even the same patient may show different symptoms at different stages or stages. .

Delusion is the most common and important obstacle to thinking content. The most common delusions are victim delusions, relationship delusions, influence delusions, jealous delusions, exaggerated delusions, non-blood delusions, etc. It is estimated that up to 80% of patients with schizophrenia have a delusion of victimization. The delusions of victimization can manifest as different degrees of insecurity, such as being monitored, excluded, worried about being administered drugs, or murdered.

There is a certain correlation between the symptoms of cognitive deficits and other psychotic symptoms. For example, the symptoms of cognitive deficits are more pronounced in patients with significant form disorders, the symptoms of cognitive deficits are more obvious in patients with significant negative symptoms, and cognitive deficits may be related to certain positives. Symptoms are related. Cognitive deficits may occur before the psychiatric symptoms become clear (such as the prodromal phase), or they decline sharply with the onset of psychiatric symptoms, or they gradually decline as the course of the disease increases. Cognitive deficits are more pronounced in patients with schizophrenia.

Clozapine, the first-generation and atypical antipsychotic, is used as a second-line drug. Some patients with acute stage or patients with poor efficacy can be treated with electroconvulsions.

10% to 30% of patients with schizophrenia are ineffective and are called refractory schizophrenia.
