Yes, there are minor cases of schizophrenia. It normally does get a little worse as you age, an example of this is younger children can show a couple of symptoms but a diagnosis is normally not made until about age 17+. Though, symptoms do not normally show until late adolescence / early adulthood. Schizophrenia is defined as ‘a mental disorder characterized by abnormalities in the perception or expression of reality’. I always thought of it as not being able to tell the difference between reality and dreams. The types are
The defining feature of the paranoid subtype is the presence of auditory hallucinations or prominent delusional thoughts about persecution or conspiracy. However, people with this subtype may be more functional in their ability to work and engage in relationships than people with other subtypes of schizophrenia.
As the name implies, this subtype’s predominant feature is disorganization of the thought processes. As a rule, hallucinations and delusions are less pronounced, although there may be some evidence of these symptoms. These people may have significant impairments in their ability to maintain the activities of daily living. Even the more routine tasks, such as dressing, bathing or brushing teeth, can be significantly impaired or lost.
Often, there is impairment in the emotional processes of the individual. For example, these people may appear emotionally unstable, or their emotions may not seem appropriate to the context of the situation. They may fail to show ordinary emotional responses in situations that evoke such responses in healthy people.
The predominant clinical features seen in the catatonic subtype involve disturbances in movement. Affected people may exhibit a dramatic reduction in activity, to the point that voluntary movement stops, as in catatonic stupor. Alternatively, activity can dramatically increase, a state known as catatonic excitement.
Other disturbances of movement can be present with this subtype. Actions that appear relatively purposeless but are repetitively performed, also known as stereotypic behavior, may occur, often to the exclusion of involvement in any productive activity.
This subtype is diagnosed when the patient no longer displays prominent symptoms. In such cases, the schizophrenic symptoms generally have lessened in severity. Hallucinations, delusions or idiosyncratic behaviors may still be present, but their manifestations are significantly diminished in comparison to the acute phase of the illness.
