What type of person tends to suffer from schizophrenia? A person with schizoid is often unsocial, introverted, lonely, and passive-dependent is more likely to suffer from schizophrenia. A person who was bullied in early childhood does not fight back and has a reactive attitude.
The symptoms of schizophrenia are usually divided into positive and negative categories. The former occurs with the pathological activity of the central nervous system, such as hallucination, a monologue, delusion, and excitement. The latter comprises the psychological inertia that occurs with decreased activity of the central nervous system, such as decreased motivation. Ego leakage symptom and broadcasting of thought are also sometimes observed.
Another impairment in cognitive function is that a schizophrenic patient tends to worry about unrelated stories, which may lead to attention deficit. A psychiatrist will tend to first detect decreased cognitive function of short-term memory and attentiveness as symptoms before positive or negative symptoms emerge.
A person suffering from schizophrenia can easily become stressed and overwhelmed with information. Normally, the information from sense organs is filtered by the hypothalamus in the brain. However, when information is more than what the brain can process, the hypothalamus filter functions. A schizophrenic patient cannot process normal amounts of information properly and thus exhibits symptoms of disorganization.
