Antiglucocorticoid Therapy for Cognitive Impairment in Late-life Anxiety Disorders (Mifepristone)
2020年8月7日 更新者：Washington University School of Medicine
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.

详细说明
Currently, no treatment exists to address cognitive impairment in late-life anxiety disorders.
In this study, fifteen patients aged 60+ with an anxiety disorder (current or in partial remission) and subjective and/or objective evidence of cognitive impairment will receive treatment with mifepristone.
At the baseline visit participants will be randomized to receive either mifepristone 300mg or a placebo daily for 7 days.
Participants will be reassessed after 7 days (week 1 visit) of receiving study medication (mifepristone or placebo).
At that time all participants will be provided mifepristone 300mg daily for the remaining 3 weeks of study treatment.
The primary outcome measure will be neurocognition, as assessed by a battery of neuropsychological measures focusing on immediate and delayed memory and executive function (administered at baseline, week 1, week 4, and week 12).
Saliva samples for cortisol measurement will be collected immediately following the baseline visit and week 4 visit.
Secondary outcomes will be self-reported anxiety and depressive symptoms.

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.
