Arms | Assigned Interventions |
---|---|
1: Active Comparator
Healthy participants who undergo functional magnetic resonance imaging (fMRI)
|
Behavioral: Picture response during fMRI
While undergoing an fMRI scan, participants will be presented with pictures, letters, words, and sounds to evoke emotional responses. There will be a maximum of three MRI scans over 9 weeks.
|
2: Experimental
Participants with bipolar disorder who undergo fMRI
|
Behavioral: Picture response during fMRI
While undergoing an fMRI scan, participants will be presented with pictures, letters, words, and sounds to evoke emotional responses. There will be a maximum of three MRI scans over 9 weeks.
|
3: Experimental
Participants with bipolar disorder who undergo fMRI and lithium treatment
|
Drug: Lithium
Dosing will start as one 300-mg capsule per day and will be titrated up to four 300-mg capsules per day for a total of 8 weeks of treatment.
Behavioral: Picture response during fMRI
While undergoing an fMRI scan, participants will be presented with pictures, letters, words, and sounds to evoke emotional responses. There will be a maximum of three MRI scans over 9 weeks.

Bipolar disorder (BD) is a chronic brain disorder that causes dramatic changes in a person's mood and energy. People with BD undergo periods of extreme happiness and extreme sadness, known as episodes of mania and depression. A person undergoing an episode of mania often experiences euphoric moods, increased energy, and aggressive behaviors, while a person in a depressed state often experiences low moods, lack of energy, and feelings of sadness. Researchers have recently discovered that abnormalities in certain brain areas that control emotion are often present in those with BD. It is believed that the severe mood shifts in BD may cause alterations in normal brain activity, specifically in corticolimbic activation and connectivity. Current mood stabilizing medications used to treat people with BD may help normalize these brain activity abnormalities. This study will assess the effects of BD on brain activity using functional magnetic resonance imaging (fMRI) and will determine if treatment with lithium changes the brain activity in people with BD.
This 9-week study will include both participants who are healthy and participants with BD. All potential participants will undergo initial testing, which will include a physical examination, blood tests, and an electrocardiogram (EKG). Participants will also be asked to answer questions about their mental health, drug use, personality, family history, and psychological well-being. Both groups of eligible participants will then return on a different day to undergo an MRI scan, taking 4 hours to complete. During the scan, participants will be asked to perform tasks designed to show changes in blood flow in specific brain regions. These tasks will include listening to sounds and looking at various letters, words, and pictures. This will mark the completion of the study for healthy participants and those participants with BD who do not wish to receive medication treatment.
Following the first MRI scan, participants with BD who wish to undergo medication treatment will begin an 8-week course of lithium. Participants will be asked to come to the clinic at least once a week for medication monitoring visits. During these visits, participants will undergo blood draws and assessments on depression and mania. Participants will return for two repeat MRI scans after Weeks 2 and 8 of lithium treatment.
