What normal functions are reduced or absent in individuals with schizophrenia?

Schizophrenia is a mental disorder characterized by a breakdown of thinking, emotions, and behavior. Individuals with schizophrenia may experience a variety of symptoms, including delusions, hallucinations, disorganized speech, and social withdrawal. In addition to these symptoms, people with schizophrenia may also have difficulty with certain cognitive functions, including:

Attention: Schizophrenia can impair the ability to pay attention to things, such as conversations, lectures, or instructions.

Memory: Schizophrenia can also affect memory, making it difficult to recall information or learn new things.

Executive function: Executive function refers to the ability to control one's behavior and thoughts. Schizophrenia can impair executive function, making it difficult to plan, solve problems, or make decisions.

Social cognition: Social cognition refers to the ability to understand and interact with others. Schizophrenia can impair social cognition, making it difficult to understand the feelings and intentions of others, or to interact with them in a socially appropriate manner.

Emotion: Schizophrenia can also affect emotion, making it difficult to experience pleasure or feel close to others.

These are just a few of the normal functions that can be reduced or absent in individuals with schizophrenia. The severity of these symptoms can vary from person to person, and they may come and go over time. However, these symptoms can have a significant impact on the lives of people with schizophrenia, making it difficult to work, go to school, or participate in social activities.
