GENERAL INFORMATION
The NIMH Schizophrenia
Research Program consists of an 11 bed hospital unit, located at the NIH campus in
Bethesda, Maryland, where those who suffer from schizophrenia live without charge while
participating in research.
Overview of the Program
The purpose of the
research is to study the biological and neurological aspects of schizophrenia
and related syndromes, and to examine the effectiveness of treatment for these
disorders.
The Purpose of the research is to study the biological
and neurological aspects of schizophrenia…
Upon admission,
participants undergo an extensive medical and research evaluation including a
physical examination, comprehensive neurological testing, psychological testing
and diagnostic interviews. The evaluation may last several weeks and is followed
by several months of research participation. The program provides individually
tailored clinical treatment prior to discharge.
Length of Stay
Length of stay in the program varies depending
on the particular research studies undertaken and can last from approximately three
to nine months, with the average stay being about six months.
Who can participate
Prospective research
participants must be:
- Diagnosed with schizophrenia or schizoaffective disorder
- 18-55 years old
- Medically healthy
- Free of neurological problems (such as epilepsy)
- Free of drug and alcohol abuse for at least six months with no more than a
five-year history of heavy use
- Free of severe developmental disorder (such as mental retardation)
- Able to understand the research program
- Be willing to consent to participation in the research protocols
Persons who are currently at risk of violent behavior toward self
or others are not eligible.
Because participation is strictly voluntary, individuals are free
to withdraw from the research protocols and/or the hospital at any time.
Current Studies
Current studies use state-of-the-art
neuroimaging (a way of taking pictures of the brain) to study schizophrenia.
Specialized tests such as magnetic resonance imaging (MRI), functional magnetic
resonance imaging (fMRI), positron emission tomography (PET), and
single photon tomography (SPECT) produce pictures (“scans”) of the inside of the brain
so we can better understand how the brain reacts to antipsychotic medications. The
effect of medication can be seen and compared to a later scan taken after medications
have been changed. In addition, these tests enable us to study the frontal lobe of the
brain, which is needed for goal planning, social functioning, and personality
organization.

MRI imaging uses a magnetic field to take a picture of the brain.
SPECT and PET imaging use an extremely small amount of radioactively labeled tracer
drug to take a picture of the brain. These tests are very safe and the NIH carefully
monitors radiation exposure to keep it well within safe limits. They require participants
to sit or lie in place for approximately thirty minutes to two hours, depending
on the type of scan.
It is extremely important
for us to have some images of brain activity without the interference of any medication.
This allows us to better study a person’s brain and how it functions. This also helps us
to separate the effects of schizophrenia from the side effects of medication and to
confirm the diagnosis of the patient. Participants will be asked to go without medication
for approximately four weeks.
Most individuals
participate in several neuroimaging studies throughout their stay. There is an
approximately eight-week period during which participants will be given
antipsychotic medication for four weeks and placebo (no medication) for four weeks.
Participants will not be told when the medication-free period will occur.
During the eight-week study, participants will take unidentified capsules
every day. Neither the participant nor the nursing staff will know when the capsules
contain medication. This allows participants and staff to evaluate symptoms without bias.
The medications used
during this period are antipsychotic medications that are used in standard
practice. Through these studies we can learn more about the mechanisms of these
medications which we hope will lead to better medication treatment for those
suffering from mental illness. In addition, we hope to learn more about each research
participant’s clinical response so that recommendations can be made to them, their
families, and their future mental health caregivers.
Occasionally, we study
experimental drugs that are only available in research centers. We attempt to learn
which of these drugs may be effective. We hope that they
might lead to new directions in the development of medications for the treatment
of schizophrenia. We recognize participants in these studies as pioneers in the cause
for better treatment and
we are grateful for their efforts.
Most individuals participate in neuroimaging studies throughout their
stay.
The research staff
discusses possible benefits, risks, and side effects of each study with the
participant prior to their inclusion. Participants are asked to sign a written protocol
each time a new study is begun. An individual’s right to refuse participation in a
particular protocol is respected at all times. Family members, with the participant’s
consent, may be kept informed of upcoming research
activities.
Life on the Residential Unit
Clinical research care is
provided by an experienced psychiatrist and supervised by a senior staff
member. A well-trained nursing staff provides psychiatric nursing care and participates
actively in evaluations, research, and treatment efforts. Occupational therapy,
recreational therapy, art and music, therapy supportive and social skills groups are all part of the program.

A staff social workers
assists each patient and family in understanding the research process, in
gaining a better understanding of the illness, and in helping the family plan
for the participant’s discharge. Because of the difficulties that may arise
during discharge planning, participants and their families are encouraged to
have a specific housing plan in place before they are admitted to the
program
Free Treatment
Participation in the program involves no cost to the family or
participant, except for travel to and from the program. The program is
funded by the Federal Government through the Department of Health and Human
Services.
You should also know
Participants are required
to go through a medication-free period for several weeks to learn more about the
nature of schizophrenia without the confounding effects of medication. This frequently
leads to an increase in symptoms. Occasionally, observations from the medication-free
period confirm the diagnosis or affect decisions regarding medication needs for an
individual. The impact of going medication free is different for every individual and
should be thoughtfully considered when deciding to apply to the program.
Keep in mind that this
program does not have unique answers or a cure for schizophrenia. Participants might not
benefit from their participation in the program. Because of the intensive evaluation,
excellent clinical care, and individual attention, modest improvements for many
participants have been achieved. The program also provides, for some families, a needed
respite.
There is an urgent need
for greater knowledge concerning the causes of and treatment for schizophrenia
and related disorders. By participating in research, you can make a significant
contribution to our mission of understanding and finding better treatments for
schizophrenia.
