Overview

The University of California, Los Angeles, is conducting a clinical trial that examines the effect of inflammatory challenges on insomnia in elderly patients with depression. After participants are assessed, researchers are attempting to offer treatment based on their results.

Study Information

Since chronic inflammatory and insomnia can lead to depression in some older adults, researchers are seeing if reducing an inflammatory change in patients with insomnia can produce results. The study will compare two groups of 80 elderly participants, those with and those without insomnia, and examine the result similarities and differences.

Inclusion Criteria

• All sexes, ages 60 to 80 years old
• Currently in good general health, evaluated by pre-screening process
• Half the participants will be required to be currently diagnosed with insomnia disorder
• The other half will be required to be determined not to have insomnia disorder

• Previous history of fainting during blood draws.
• Presence of comorbid medical conditions including cardiovascular (e.g., history of acute coronary event, stroke) and neurological diseases (e.g., Parkinson’s disease), as well as pain disorders
• Presence of comorbid inflammatory disorders such as rheumatoid arthritis or other autoimmune disorders
• Presence of uncontrolled medical condition(s) that may interfere with study
• Presence of chronic infection
• Presence of an acute infectious illness in the two weeks before study
• Currently have an Axis I psychiatric disorder including major depressive order or substance dependence
