Study Summary

Studies in humans and animals support that stress and/or elevations in corticosteroids lead to changes in hippocampal structure and functioning. This is important as patients with major depression frequently have elevated cortisol, and millions of patients receive prescription corticosteroids (e.g. prednisone). Both depression and corticosteroid therapy are associated with memory impairment and hippocampal atrophy. Our research uses corticosteroid-treated patients to explore interventions that might protect the brain from the effects of stress or corticosteroids. We propose to give 30 corticosteroid-treated asthma patients acetaminophen or placebo. Between group differences in mood, memory and other neurocognitive measures will serve as outcome measures.

Primary Outcome

This is a measure of declarative memory (associated with the hippocampus). The test consists of 15 nouns read aloud for five consecutive trials with each trial followed by a free-recall trial. Following the fifth trial, an interference list of 15 different words is presented followed by a free-recall trial of that list. Delayed recall of the first list is tested immediately following the interference list and after a 20-minute delay. A recognition test of 50 words including the 15 original words
