Antiglucocorticoid Therapy for Cognitive Impairment in Late-life Anxiety Disorders (Mifepristone)
This study seeks to develop and test a novel, mechanistic treatment for mitigating cognitive impairment in older adults with anxiety disorders. Anxiety disorders are common, severe, and disabling in older adults. One particularly impairing aspect of late-life anxiety disorders is cognitive impairment: impairments in memory and executive function cause disability, impede treatment response to psychotherapy, may lead to dementia, and are not corrected by standard anti-anxiety treatments.
This pilot study will test the glucocorticoid antagonist, mifepristone, for cognitive impairment in late-life anxiety disorders. Mifepristone blocks the effects of elevated cortisol levels on glucocorticoid receptors in the brain; it has been studied preliminarily in various neuropsychiatric disorders, such as psychotic depression and bipolar disorder, with well-documented safety and tolerability.

Memory composite z-score: The two memory measures were a 16-word list recall similar to the Rey auditory verbal learning test, which has been used by the Washington University Alzheimer's Disease Research Center; and two paragraphs from a set of paragraph recall tests validated as sensitive to effects of stress-level glucocorticoids.
For each memory variable, a z score was computed for each participant, where z score = (participant score mean)/standard deviation.
Then a single composite memory variable was created by summing up these z scores.
Summed Z-scores range from -6 to 6, with scores above 0 being higher than the mean.
