Cognitive Deficits in Major Depressive Disorder and Bipolar Disorder, Depressed Type: Prevalence and Improvement With Treatment of Depressive Symptoms

14. november 2013 opdateret af: John D. Matthews, Massachusetts General Hospital

Cognitive Deficits in Major Depressive Disorder and Bipolar Disorder Depressed Type: Prevalence and Symptoms With Treating of Depressive Symptoms

The purpose of this research study is to learn more about cognitive deficits in people with certain mood disorders. The mood disorders are Major Depressive Disorder (MDD) and Bipolar disorder, depressed type.

Cognitive deficits are problems with things like thinking and memory. People with cognitive deficits may have problems concentrating and paying attention. When talking, they may have trouble recalling a word they want to say. They may think slowly and have problems remembering things. These deficits can affect an individual's ability to work and function socially. Cognitive deficits that occur with depression may increase the risk of a relapse of major depressive disorder.

We want to study the course of cognitive impairment in subjects as they are receiving treatment for their depression. We want to find out if their cognitive deficits get better, worse, or stay the same.

We also want to learn more about a stress hormone called cortisol that is produced in the body. We want to study the relationship between cortisol and cognitive impairment. Recent research has shown that cognitive impairment may be more severe in people who have high levels of cortisol in their blood.

We will also measure the levels of a protein in your blood called brain-derived neurotrophic factor (BDNF). BDNF helps the growth of new brain cells. It appears that the growth of new brain cells lessens when people are depressed. Treatment with antidepressant medications may cause BDNF levels to increase and return to normal. We are interested in studying the relationship between BDNF levels and cognitive impairment throughout treatment.
