MANAGEMENT OF SCHIZOPHRENIA :

Since schizophrenia may not be a single condition and its causes are not yet known, current treatment methods are based on both clinical research and experience. These approaches are chosen on the basis of their ability to reduce the symptoms of schizophrenia and to lessen the chances that symptoms will return.
What About Medications?

Antipsychotic medications have been available since the mid-1950s. They have greatly improved the outlook for individual patients. These medications reduce the psychotic symptoms of schizophrenia and usually allow the patient to function more effectively and appropriately. Antipsychotic drugs are the best treatment now available, but they do not “cure” schizophrenia or ensure that there will be no further psychotic episodes. The choice and dosage of medication can be made only by a qualified physician who is well trained in the medical treatment of mental disorders. The dosage of medication is individualized for each patient, since people may vary a great deal in the amount of drug needed to reduce symptoms without producing troublesome side effects.
The large majority of people with schizophrenia show substantial improvement when treated with antipsychotic drugs. Some patients, however, are not helped very much by the medications and a few do not seem to need them. It is difficult to predict which patients will fall into these two groups and to distinguish them from the large majority of patients who do benefit from treatment with antipsychotic drugs.

A number of new antipsychotic drugs (the so-called “atypical antipsychotics”) have been introduced since 1990. The first of these, clozapine (Clozaril®), has been shown to be more effective than other antipsychotics, although the possibility of severe side effects – in particular, a condition called agranulocytosis (loss of the white blood cells that fight infection) – requires that patients be monitored with blood tests every one or two weeks. Even newer antipsychotic drugs, such as risperidone (Risperdal®) and olanzapine (Zyprexa®), are safer than the older drugs or clozapine, and they also may be better tolerated. They may or may not treat the illness as well as clozapine, however. Several additional antipsychotics are currently under development.

Antipsychotic drugs are often very effective in treating certain symptoms of schizophrenia, particularly hallucinations and delusions; unfortunately, the drugs may not be as helpful with other symptoms, such as reduced motivation and emotional expressiveness. Indeed, the older antipsychotics (which also went by the name of “neuroleptics”), medicines like haloperidol (Haldol®) or chlorpromazine (Thorazine®), may even produce side effects that resemble the more difficult to treat symptoms. Often, lowering the dose or switching to a different medicine may reduce these side effects; the newer medicines, including olanzapine (Zyprexa®), quetiapine (Seroquel®), and risperidone (Risperdal®), appear less likely to have this problem. Sometimes when people with schizophrenia become depressed, other symptoms can appear to worsen. The symptoms may improve with the addition of an antidepressant medication.

Patients and families sometimes become worried about the antipsychotic medications used to treat schizophrenia. In addition to concern about side effects, they may worry that such drugs could lead to addiction. However, antipsychotic medications do not produce a “high” (euphoria) or addictive behavior in people who take them.

Another misconception about antipsychotic drugs is that they act as a kind of mind control, or a “chemical straitjacket.” Antipsychotic drugs used at the appropriate dosage do not “knock out” people or take away their free will. While these medications can be sedating, and while this effect can be useful when treatment is initiated particularly if an individual is quite agitated, the utility of the drugs is not due to sedation but to their ability to diminish the hallucinations, agitation, confusion, and delusions of a psychotic episode. Thus, antipsychotic medications should eventually help an individual with schizophrenia to deal with the world more rationally.

How Long Should People With Schizophrenia Take Antipsychotic Drugs?
Antipsychotic medications reduce the risk of future psychotic episodes in patients who have recovered from an acute episode. Even with continued drug treatment, some people who have recovered will suffer relapses. Far higher relapse rates are seen when medication is discontinued. In most cases, it would not be accurate to say that continued drug treatment “prevents” relapses; rather, it reduces their intensity and frequency. The treatment of severe psychotic symptoms generally requires higher dosages than those used for maintenance treatment. If symptoms reappear on a lower dosage, a temporary increase in dosage may prevent a full-blown relapse.

Because relapse of illness is more likely when antipsychotic medications are discontinued or taken irregularly, it is very important that people with schizophrenia work with their doctors and family members to adhere to their treatment plan. Adherence to treatment refers to the degree to which patients follow the treatment plans recommended by their doctors. Good adherence involves taking prescribed medication at the correct dose and proper times each day, attending clinic appointments, and/or carefully following other treatment procedures. Treatment adherence is often difficult for people with schizophrenia, but it can be made easier with the help of several strategies and can lead to improved quality of life.
 
There are a variety of reasons why people with schizophrenia may not adhere to treatment. Patients may not believe they are ill and may deny the need for medication, or they may have such disorganized thinking that they cannot remember to take their daily doses. Family members or friends may not understand schizophrenia and may inappropriately advise the person with schizophrenia to stop treatment when he or she is feeling better. Physicians, who play an important role in helping their patients adhere to treatment, may neglect to ask patients how often they are taking their medications, or may be unwilling to accommodate a patient’s request to change dosages or try a new treatment. Some patients report that side effects of the medications seem worse than the illness itself. Further, substance abuse can interfere with the effectiveness of treatment, leading patients to discontinue medications. When a complicated treatment plan is added to any of these factors, good adherence may become even more challenging.

Fortunately, there are many strategies that patients, doctors, and families can use to improve adherence and prevent worsening of the illness. Some antipsychotic medications, including haloperidol (Haldol®), fluphenazine (Prolixin®), perphenazine (Trilafon®) and others, are available in long-acting injectable forms that eliminate the need to take pills every day. A major goal of current research on treatments for schizophrenia is to develop a wider variety of long-acting antipsychotics, especially the newer agents with milder side effects, which can be delivered through injection. Medication calendars or pill boxes labeled with the days of the week can help patients and caregivers know when medications have or have not been taken. Using electronic timers that beep when medications should be taken, or pairing medication taking with routine daily events like meals, can help patients remember and adhere to their dosing schedule. Engaging family members in observing oral medication taking by patients can help ensure adherence. In addition, through a variety of other methods of adherence monitoring, doctors can identify when pill taking is a problem for their patients and can work with them to make adherence easier. It is important to help motivate patients to continue taking their medications properly.

In addition to any of these adherence strategies, patient and family education about schizophrenia, its symptoms, and the medications being prescribed to treat the disease is an important part of the treatment process and helps support the rationale for good adherence.

What About Side Effects?
Antipsychotic drugs, like virtually all medications, have unwanted effects along with their beneficial effects. During the early phases of drug treatment, patients may be troubled by side effects such as drowsiness, restlessness, muscle spasms, tremor, dry mouth, or blurring of vision. Most of these can be corrected by lowering the dosage or can be controlled by other medications. Different patients have different treatment responses and side effects to various antipsychotic drugs. A patient may do better with one drug than another.

The long-term side effects of antipsychotic drugs may pose a considerably more serious problem. Tardive dyskinesia (TD) is a disorder characterized by involuntary movements most often affecting the mouth, lips, and tongue, and sometimes the trunk or other parts of the body such as arms and legs. It occurs in about 15 to 20 percent of patients who have been receiving the older, “typical” antipsychotic drugs for many years, but TD can also develop in patients who have been treated with these drugs for shorter periods of time. In most cases, the symptoms of TD are mild, and the patient may be unaware of the movements.
Antipsychotic medications developed in recent years all appear to have a much lower risk of producing TD than the older, traditional antipsychotics. The risk is not zero, however, and they can produce side effects of their own such as weight gain. In addition, if given at too high of a dose, the newer medications may lead to problems such as social withdrawal and symptoms resembling Parkinson’s disease, a disorder that affects movement. Nevertheless, the newer antipsychotics are a significant advance in treatment, and their optimal use in people with schizophrenia is a subject of much current research.

What About Psychosocial Treatments?
Antipsychotic drugs have proven to be crucial in relieving the psychotic symptoms of schizophrenia – hallucinations, delusions, and incoherence – but are not consistent in relieving the behavioral symptoms of the disorder. Even when patients with schizophrenia are relatively free of psychotic symptoms, many still have extraordinary difficulty with communication, motivation, self-care, and establishing and maintaining relationships with others. Moreover, because patients with schizophrenia frequently become ill during the critical career-forming years of life (e.g., ages 18 to 35), they are less likely to complete the training required for skilled work. As a result, many with schizophrenia not only suffer thinking and emotional difficulties, but lack social and work skills and experience as well.

It is with these psychological, social, and occupational problems that psychosocial treatments may help most. While psychosocial approaches have limited value for acutely psychotic patients (those who are out of touch with reality or have prominent hallucinations or delusions), they may be useful for patients with less severe symptoms or for patients whose psychotic symptoms are under control. Numerous forms of psychosocial therapy are available for people with schizophrenia, and most focus on improving the patient’s social functioning – whether in the hospital or community, at home, or on the job. Some of these approaches are described here. Unfortunately, the availability of different forms of treatment varies greatly from place to place.

• Rehabilitation :
Broadly defined, rehabilitation includes a wide array of non-medical interventions for those with schizophrenia. Rehabilitation programs emphasize social and vocational training to help patients and former patients overcome difficulties in these areas. Programs may include vocational counseling, job training, problem-solving and money management skills, use of public transportation, and social skills training. These approaches are important for the success of the community-centered treatment of schizophrenia, because they provide discharged patients with the skills necessary to lead productive lives outside the sheltered confines of a mental hospital.

• Individual Psychotherapy :
Individual psychotherapy involves regularly scheduled talks between the patient and a mental health professional such as a psychiatrist, psychologist, psychiatric social worker, or nurse. The sessions may focus on current or past problems, experiences, thoughts, feelings, or relationships. By sharing experiences with a trained empathic person – talking about their world with someone outside it – individuals with schizophrenia may gradually come to understand more about themselves and their problems. They can also learn to sort out the real from the unreal and distorted. Recent studies indicate that supportive, reality-oriented, individual psychotherapy, and cognitive-behavioral approaches that teach coping and problem-solving skills, can be beneficial for outpatients with schizophrenia. However, psychotherapy is not a substitute for antipsychotic medication, and it is most helpful once drug treatment first has relieved a patient’s psychotic symptoms.

• Family Education :
Very often, patients with schizophrenia are discharged from the hospital into the care of their family; so it is important that family members learn all they can about schizophrenia and understand the difficulties and problems associated with the illness. It is also helpful for family members to learn ways to minimize the patient’s chance of relapse – for example, by using different treatment adherence strategies – and to be aware of the various kinds of outpatient and family services available in the period after hospitalization. Family “psychoeducation,” which includes teaching various coping strategies and problem-solving skills, may help families deal more effectively with their ill relative and may contribute to an improved outcome for the patient.
 
• Self-Help Groups :
Self-help groups for people and families dealing with schizophrenia are becoming increasingly common. Although not led by a professional therapist, these groups may be therapeutic because members provide continuing mutual support as well as comfort in knowing that they are not alone in the problems they face. Self-help groups may also serve other important functions. Families working together can more effectively serve as advocates for needed research and hospital and community treatment programs. Patients acting as a group rather than individually may be better able to dispel stigma and draw public attention to such abuses as discrimination against the mentally ill.
Family and peer support and advocacy groups are very active and provide useful information and assistance for patients and families of patients with schizophrenia and other mental disorders. A list of some of these organizations is included at the end of this document.

HOW CAN OTHER PEOPLE HELP?

A patient's support system may come from several sources, including the family, a professional residential or day program provider, shelter operators, friends or roommates, professional case managers, churches and synagogues, and others. Because many patients live with their families, the following discussion frequently uses the term "family." However, this should not be taken to imply that families ought to be the primary support system.

There are numerous situations in which patients with schizophrenia may need help from people in their family or community. Often, a person with schizophrenia will resist treatment, believing that delusions or hallucinations are real and that psychiatric help is not required. At times, family or friends may need to take an active role in having them seen and evaluated by a professional. The issue of civil rights enters into any attempts to provide treatment. Laws protecting patients from involuntary commitment have become very strict, and families and community organizations may be frustrated in their efforts to see that a severely mentally ill individual gets needed help. These laws vary from State to State; but generally, when people are dangerous to themselves or others due to a mental disorder, the police can assist in getting them an emergency psychiatric evaluation and, if necessary, hospitalization. In some places, staff from a local community mental health center can evaluate an individual's illness at home if he or she will not voluntarily go in for treatment.
Sometimes only the family or others close to the person with schizophrenia will be aware of strange behavior or ideas that the person has expressed. Since patients may not volunteer such information during an examination, family members or friends should ask to speak with the person evaluating the patient so that all relevant information can be taken into account.

Ensuring that a person with schizophrenia continues to get treatment after hospitalization is also important. A patient may discontinue medications or stop going for follow-up treatment, often leading to a return of psychotic symptoms. Encouraging the patient to continue treatment and assisting him or her in the treatment process can positively influence recovery. Without treatment, some people with schizophrenia become so psychotic and disorganized that they cannot care for their basic needs, such as food, clothing, and shelter. All too often, people with severe mental illnesses such as schizophrenia end up on the streets or in jails, where they rarely receive the kinds of treatment they need.

Those close to people with schizophrenia are often unsure of how to respond when patients make statements that seem strange or are clearly false. For the individual with schizophrenia, the bizarre beliefs or hallucinations seem quite real – they are not just "imaginary fantasies." Instead of “going along with” a person's delusions, family members or friends can tell the person that they do not see things the same way or do not agree with his or her conclusions, while acknowledging that things may appear otherwise to the patient.

It may also be useful for those who know the person with schizophrenia well to keep a record of what types of symptoms have appeared, what medications (including dosage) have been taken, and what effects various treatments have had. By knowing what symptoms have been present before, family members may know better what to look for in the future. Families may even be able to identify some "early warning signs" of potential relapses, such as increased withdrawal or changes in sleep patterns, even better and earlier than the patients themselves. Thus, return of psychosis may be detected early and treatment may prevent a full-blown relapse. Also, by knowing which medications have helped and which have caused troublesome side effects in the past, the family can help those treating the patient to find the best treatment more quickly.

In addition to involvement in seeking help, family, friends, and peer groups can provide support and encourage the person with schizophrenia to regain his or her abilities. It is important that goals be attainable, since a patient who feels pressured and/or repeatedly criticized by others will probably experience stress that may lead to a worsening of symptoms. Like anyone else, people with schizophrenia need to know when they are doing things right. A positive approach may be helpful and perhaps more effective in the long run than criticism. This advice applies to everyone who interacts with the person.

WHAT IS THE OUTLOOK?

The outlook for people with schizophrenia has improved over the last 25 years. Although no totally effective therapy has yet been devised, it is important to remember that many people with the illness improve enough to lead independent, satisfying lives. As we learn more about the causes and treatments of schizophrenia, we should be able to help more patients achieve successful outcomes.

Studies that have followed people with schizophrenia for long periods, from the first episode to old age, reveal that a wide range of outcomes is possible. When large groups of patients are studied, certain factors tend to be associated with a better outcome – for example, a pre-illness history of normal social, school, and work adjustment. However, the current state of knowledge, does not allow for a sufficiently accurate prediction of long-term outcome.

Given the complexity of schizophrenia, the major questions about this disorder – its cause or causes, prevention, and treatment – must be addressed with research. The public should beware of those offering "the cure" for (or "the cause" of) schizophrenia. Such claims can provoke unrealistic expectations that, when unfulfilled, lead to further disappointment. Although progress has been made toward better understanding and treatment of schizophrenia, continued investigation is urgently needed. As the lead Federal agency for research on mental disorders, NIMH conducts and supports a broad spectrum of mental illness research from molecular genetics to large-scale epidemiologic studies of populations. It is thought that this wide-ranging research effort, including basic studies on the brain, will continue to illuminate processes and principles important for understanding the causes of schizophrenia and for developing more effective treatments.
