中文摘要
项目摘要
60岁以上的女性中有五分之一患有急迫性尿失禁,这种情况与以下疾病有关:
抑郁、社交孤立、身体机能下降和丧失独立生活能力。目前
最常用的急迫性尿失禁的治疗是抗胆碱能药物,
抑制膀胱的不自主收缩。不幸的是,多项观察性研究表明,
抗胆碱能膀胱治疗可能对认知有不良影响,这是基于
老年痴呆症患者开这些药。因此,人们普遍担心,
老年失禁患者服用抗胆碱能药物希望改善膀胱状况
控制可能会使自己面临更大的风险,由于认知障碍的功能妥协。
然而,迄今为止,将抗胆碱能膀胱药物与痴呆症联系起来的数据来自于
回顾性观察分析而不是前瞻性试验。少数(主要是行业赞助)
使用抗胆碱能膀胱治疗直接评估老年人认知功能的研究,
小而矮,使用相对不敏感的认知筛查措施,限制了他们的能力,
发现认知上有意义的变化。而另一种治疗尿失禁的非抗胆碱能药物
(theβ-3-激动剂药物米拉贝隆)现已上市,很少有研究比较这种药物的作用。

评估老年人的认知能力。在缺乏不利认知影响的严格证据的情况下,
抗胆碱能膀胱药物继续被广泛地开给社区中的老年患者,
包括那些已知有认知障碍、阿尔茨海默病和相关痴呆症的人。
为了解决这个问题,我们将进行一项严格的、前瞻性的随机研究,

英文摘要
PROJECT SUMMARY
One in five women over the age of 60 suffers from urgency incontinence, a condition associated with
depression, social isolation, physical function decline, and loss of ability to live independently. Currently, the
most commonly used treatments for urgency incontinence are anticholinergic medications designed to
suppress involuntary contractions of the bladder. Unfortunately, multiple observational studies have suggested
that anticholinergic bladder therapy may have adverse effects on cognition, based on higher rates of
diagnosed dementia in older patients prescribed these medications. As a result, there is widespread concern
that older incontinent patients who take anticholinergic medications in the hopes of improving their bladder
control may be exposing themselves to greater risk of functional compromise due to cognitive impairment.
To date, however, the data linking anticholinergic bladder medications with dementia are derived from
retrospective observational analyses rather than prospective trials. The few (and primarily industry-sponsored)
studies directly assessing cognitive function in older adults using anticholinergic bladder therapy have been
small and short and have used relatively insensitive cognitive screening measures, limiting their ability to
detect meaningful changes in cognition. While an alternate, non-anticholinergic medication for incontinence
(the beta-3-agonist drug mirabegron) is now available, very little research has compared the effects of this
medication to that of anticholinergic bladder therapy, and none has involved comparative prospective
assessments of cognition in older adults. In the absence of rigorous evidence of adverse cognitive effects,
anticholinergic bladder medications continue to be widely prescribed to older patients in the community,
including those with known cognitive impairment, Alzheimer’s disease, and related dementias.
To address this issue, we will conduct a rigorous, prospective, randomized study to evaluate extended
cognitive, urinary, and functional trajectories in ~270 older incontinent women without pre-existing dementia.
Women with frequent urgency incontinence and normal or mildly impaired cognitive function at baseline will be
assigned to receive standard anticholinergic, beta-3 agonist, or no pharmacologic treatment (placebo) in
addition to patient-directed, evidence-based information about behavioral management of incontinence. Over
1, 6, and 9 months, we will compare cognitive, urinary, and other functional and quality-of-life outcomes of
anticholinergic therapy in comparison to beta-3-agonist therapy and placebo. This research address the urgent
need for rigorous evidence to determine the effects of pharmacologic incontinence treatment strategies on both
cognitive impairment and incontinence, as two of the most common (and frequently comorbid) conditions that
cause older women to transition from living independently to entering long-term care facilities.
