Some early signs of schizophrenia include senses that are too acute, an awkward walk, difficulty focusing on slow objects, constant pacing, and an inability to develop or maintain relationships, notes Schizophrenia.com. In most cases, schizophrenia manifests between 15 and 25 years of age, developing over several years or quite rapidly.
Schizophrenia affects about 1 percent of the general population, and symptoms come in six different categories: physical symptoms, behavior, feelings and mood, delusions, cognitive problems and hallucinations. In general, moving from one extreme toward another (and back) with regard to emotional and mental stimuli is an element that most of the symptoms have in common, according to Schizophrenia.com.
A sense of detachment from emotion, or an inability to sense emotion, is the dominant emotion-based symptom of schizophrenia, although an extreme sensitivity to insults or criticism is also on the list. In terms of mood, a combination of sudden anger and ongoing depression and lack of motivation mark the schizophrenic, although rapid mood swings are also a symptom. Because so many people deal with emotions and other stimuli differently, only a qualified psychiatrist or psychologist can provide a proper diagnosis of schizophrenia based on clinical history, symptoms and criteria as set out in the DSM-IV, as stated by Schizophrenia.com.
