Brief Summary

This study is dedicated to achieving a better understanding of how the brain processes information. Specifically, the investigators are studying cognitive function, thought process, and impulsivity in people with and without suicidal thoughts. You are being asked to participate in a research study to learn how the use of a medication, risperidone, improves your symptoms of depression. Specifically the investigators are studying the effectiveness of reducing the thought of suicide and other symptoms of severe depression. Risperidone is approved by FDA for the treatment of schizophrenia and bipolar mania, and clinical practice suggests that it might benefit patients with major depressive disorder. During clinical trials with 2607 patients, risperidone was proved to be safe. This is a pilot study to test a new indication of risperidone for treatment of severe depression. The study medication will be given in addition to usual psychiatric care.

Detailed Description

Men and women between the ages of 19-64, who have a diagnosis of major depressive disorder, and are currently in a severe depressive episode with suicidal thoughts, are eligible to participate in this voluntary research study. A control group will consist of men and women between the ages of 19-64 who have a diagnosis or major depressive disorder and are currently in a severe depressive episode but are not having suicidal thoughts.

During the screening visit, appropriate demographic, medical, and psychiatric data will be collected, including a diagnostic assessment and an assessment of the severity of your depression. You will be asked to complete several pen and pencil questionnaires to learn more about your current state of mind. This evaluation will take approximately two hours. If you qualify for the control or assessment group, you will be asked to meet with researchers again at 2, 4 and 6 days after your initial evaluation. If you qualify for the study group, you will be randomly (like the flip of a coin) assigned by a computer to receive either risperidone (1-2 mg/day) or placebo once a day by mouth. You will take the study medication for 5 nights in addition to your standard of care antidepressant prescribed by your doctor.

Forty participants will enter a double-blind study, which means that neither you nor your doctors will know which study medicine (risperidone or placebo) you are receiving. If medically necessary, the medication information will be released so your doctor can find out what medicine you were randomly assigned to.

You will have a follow-up evaluation (either in the hospital or returning for an office visit) at Day 5. At this visit, you will be evaluated by a psychiatrist and will be asked to complete questionnaires designed to assess the effect of the study medications on your symptoms. At this visit you will also be asked about possible side effects and how you are tolerating the medicine. These visits should take approximately one hour each.

At the screening and the end of the five day treatment, additional neuropsychological evaluations will be administered to assess your progress. These additional assessments will take approximately one hour to complete.

Members of the control group will receive no study related medications and will not return for a follow up visit.

Information for Women of Childbearing Potential or Men Fathering a Child Because risperidone may affect mother's milk or a developing fetus, breast-feeding and pregnant women are not allowed to take part in the study. Women who can become pregnant must take a pregnancy test before the start of the study. Unless they cannot have children because of surgery or other medical reasons, men and women must have been using an effective method of birth control before starting the study. Effective birth control includes birth control pills, patch, IUD, condom, sponge, diaphragm with spermicide, or avoiding sexual activity that could cause pregnancy.

Optional functional MRI(fMRI) brain Sub-study

10 participants will participate in the fMRI sub-study, which will include a 5 day open-label trial of risperidone. An fMRI scan will be done prior to receiving study drug and 5 days later. During this fMRI, a picture of your brain will be obtained. The fMRI procedure requires you to lie still on a narrow table with a circular scanner around your head. The fMRI scan takes approximately 40 minutes. Two of the neuropsychological assessments will be administered during the scan. Sub-study participants will complete a computer-based version of the tasks that will be performed during the fMRI scan prior to the brain imaging session. This is necessary to ensure you understand the tasks you will be performing while the imaging is taking place. Electing not to participate in this sub-study will not jeopardize participation in the drug trial. A neurologist, Dr. Lawrence Ver Hoef will review the MRI scans for incidental findings.
