Ramelteon in the Treatment of Sleep and Mood in Patients With Seasonal Affective Disorder
Summary
The purpose of this study is to determine whether treating sleep difficulties in patients with seasonal affective disorder also improves their depressive symptoms.
Description
Seasonal affective disorder(SAD) is a type of depression in which a patient's depressive symptoms worsen in the winter. These patients' depressive symptoms often lessen in the spring and summer months. Much of the focus of the treatment of SAD (light therapy and melatonin) has involved the brain's suprachiasmatic nucleus(SCN), as it is hypothesized that one potential reason for SAD is a desynchronized SCN. Ramelteon offers a new and more pharmacologically exact mechanism to re-synchronize the SCN. The administration of ramelteon for this patient population may improve sleep, and in addition, do so in a manner that may also reduce their seasonal affective depressive symptoms. Patients eligible for enrollment will be administered either ramelteon or placebo and return to the study office for 4 monthly visits over the winter months, to evaluate the effects of ramelteon versus placebo on sleep and mood.

Medical and Biotech [MESH] Definitions
Seasonal Affective Disorder
A syndrome characterized by depressions that recur annually at the same time each year, usually during the winter months. Other symptoms include anxiety, irritability, decreased energy, increased appetite (carbohydrate cravings), increased duration of sleep, and weight gain. SAD (seasonal affective disorder) can be treated by daily exposure to bright artificial lights (PHOTOTHERAPY), during the season of recurrence.
Cyclothymic Disorder
An affective disorder characterized by periods of depression and hypomania. These may be separated by periods of normal mood.
Bipolar Disorder
A major affective disorder marked by severe mood swings (manic or major depressive episodes) and a tendency to remission and recurrence.
Depressive Disorder
An affective disorder manifested by either a dysphoric mood or loss of interest or pleasure in usual activities. The mood disturbance is prominent and relatively persistent.
Therapeutic Misconception
Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.
