Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to explore if Bright Light Therapy (BLT) as augmentation of depression treatment on an acute psychiatric floor is feasible, helps alleviate depressive symptoms, improve functioning, and decrease length of stay on the psychiatric floor.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Background:

Bright light therapy is an evidence-based treatment for seasonal depression (SAD), recently there is evidence that it has some efficacy in nonseasonal major depressive disorder (MDD) when used together with antidepressants.

BLT works via the patient's eyes through

1. Melanopsin (Intrinsic Photo receptor ganglion Cells)
2. Suprachiasmatic Nucleus (SCN, master clock) which follows a rhythmic change
3. Serotonin

A number of studies showed seasonal changes in serotonergic parameters, including brain serotonin concentration and turnover. There were no research on using the BLT on the acute inpatient floor to augment the antidepressant treatment. Yet, there is a great need for such augmentation as for Selective Serotonin Reuptake Inhibitors (SSRI) to take full effect 4-6 weeks needed. Moreover, patients with depression often do not spend enough time on the direct sun light, which exacerbate and prolong their depressed mood. The augmentation with the BLT on the acute psychiatric floor will help the antidepressant work, expedite the recovery, and potentially shortens the length of stay in the hospital, which in turn will lead to an economic saving and faster return of the patient into the community and to the workforce.

Method:

This is an observational, case series study. All patients that meet exclusion criteria will have equal chance to receive BLT. We will administer the questionnaires before the BLT and at the end of treatment. Patient will continue to receive the pharmacological and therapeutic treatment on psychiatric floor as usual during the BLT. We will evaluate the changes in the questionnaires before and after BLT treatment, the length of stay on the unit. We will analyze the contributing factors such as age, gender, duration of depressive symptoms, other psychiatric and medical comorbidities, social factors (homelessness, social support, etc), current psychiatric medications.

Eligible patients will be invited to participate and consent will be obtain.

* The type of light we use is the "Sun Box Sun Square +"
* Emits about 10,000 lux of light and is wide enough to be used for more than 2 people.
* 186 watts
* Full spectrum 5000k white light (without the UV)
* It has an inbuilt spectrally transparent prismatic diffuser that blocks UV, that does not filter the quality of light and will not yellow.
* Minimal heat and no bulb flutter.
* Where: Bedroom / Common sitting area
* Reading/ Having breakfast/ Watching tv/Drawing
* Just after awakening within an hour early morning
* 30 mins/day
* Must have eyes open, but not looking into the light
* Staff will monitor while the patients are under the BLT
