Research
Schizophrenia is found all over the world. The severity of the symptoms and long-lasting, chronic pattern of schizophrenia often cause a high degree of disability. Medications and other treatments for schizophrenia, when used regularly and as prescribed, can help reduce and control the distressing symptoms of the illness. However, some people are not greatly helped by available treatments or may prematurely discontinue treatment because of unpleasant side effects or other reasons. Even when treatment is effective, persisting consequences of the illness – lost opportunities, stigma, residual symptoms, and medication side effects – may be very troubling. The first signs of paranoid schizophrenia often appear as confusing, or even shocking, changes in behavior. Coping with the symptoms of schizophrenia can be especially difficult for family members who remember how involved or vivacious a person was before they became ill. The sudden onset of severe psychotic symptoms is referred to as an “acute” phase of schizophrenia. “Psychosis,” a common condition in schizophrenia, is a state of mental impairment marked by hallucinations, which are disturbances of sensory perception, and/or delusions, which are false yet strongly held personal beliefs that result from an inability to separate real from unreal experiences. Less obvious symptoms, such as social isolation or withdrawal, or unusual speech, thinking, or behavior, may precede, be seen along with, or follow the psychotic symptoms. Some people have only one such psychotic episode; others have many hallucinations during a lifetime, but lead relatively normal lives during the interim periods. However, the individual with “chronic” schizophrenia, or a continuous or recurring pattern of illness, often does not fully recover normal functioning and typically requires long-term treatment, generally including medication, to control the symptoms. Making A DiagnosisIt is important to rule out other illnesses, as sometimes people suffer severe mental symptoms or even psychosis due to undetected underlying medical conditions. For this reason, a medical history should be taken and a physical examination and laboratory tests should be done to rule out other possible causes of the symptoms before concluding that a person has schizophrenia. In addition, since commonly abused drugs may cause symptoms resembling schizophrenia, blood or urine samples from the person can be tested at hospitals or physicians’ offices for the presence of these drugs. At times, it is difficult to tell one mental disorder from another. For instance, some people with symptoms of schizophrenia exhibit prolonged extremes of elated or depressed mood, and it is important to determine whether such a patient has schizophrenia or actually has a manic-depressive (or bipolar) disorder or major depressive disorder. Persons whose symptoms cannot be clearly categorized are sometimes diagnosed as having a “schizoaffective disorder.”
Children over the age of five can develop schizophrenia, but it is very rare before adolescence. Although some people who later develop schizophrenia may have seemed different from other children at an early age, the psychotic symptoms of schizophrenia – hallucinations and delusions – are extremely uncommon before adolescence.
People with schizophrenia may have perceptions of reality that are strikingly different from the reality seen and shared by others around them. Living in a world distorted by hallucinations and delusions, individuals with schizophrenia may feel frightened, anxious, and confused. In part because of the unusual realities they experience, people with schizophrenia may behave very differently at various times. Sometimes they may seem distant, detached, or preoccupied and may even sit as rigidly as a stone, not moving for hours or uttering a sound. Other times they may move about constantly – always occupied, appearing wide-awake, vigilant, and alert.
Hallucinations and illusions are disturbances of perception that are common in people suffering from schizophrenia. Hallucinations are perceptions that occur without connection to an appropriate source. Although hallucinations can occur in any sensory form – auditory (sound), visual (sight), tactile (touch), gustatory (taste), and olfactory (smell) – hearing voices that other people do not hear is the most common type of hallucination in schizophrenia. Voices may describe the patient’s activities, carry on a conversation, warn of impending dangers, or even issue orders to the individual. Illusions, on the other hand, occur when a sensory stimulus is present but is incorrectly interpreted by the individual.
Delusions are false personal beliefs that are not subject to reason or contradictory evidence and are not explained by a person’s usual cultural concepts. Delusions may take on different themes. For example, patients suffering from paranoid-type symptoms – roughly one-third of people with schizophrenia – often have delusions of persecution, or false and irrational beliefs that they are being cheated, harassed, poisoned, or conspired against. These patients may believe that they, or a member of the family or someone close to them, are the focus of this persecution. In addition, delusions of grandeur, in which a person may believe he or she is a famous or important figure, may occur in schizophrenia. Sometimes the delusions experienced by people with schizophrenia are quite bizarre; for instance, believing that a neighbor is controlling their behavior with magnetic waves; that people on television are directing special messages to them; or that their thoughts are being broadcast aloud to others.
