Mood Disorders

Researchers in the Mood Disorders program at NKI investigate the neurobiology of mood disorders, including major depressive disorder and bipolar disorder, as well as cognitive disorders (such as Alzheimer’s disease), and novel treatments for these conditions, including pharmacological agents and brain stimulation strategies.

Our past work includes the clinical and mechanistic study of novel, rapidly acting treatments for mood disorders, such as ketamine, minocycline, low field magnetic stimulation, and the recognition and treatment of cognitive deficits associated with mood disorders.

Our current studies focus on transcranial photobiomodulation – which is being tested, separately, in subjects with major depression and in those with early-stage Alzheimer’s disease. 

In our studies we use multiple neuroimaging methods – such as functional MRI (fMRI), magnetic resonance spectroscopy, and positron emission tomography (18F-MK6240 PET) – as well as quantitative electroencephalography and neuropsychological testing to investigate associated neurobehavioral substrates.
