Strong Anticholinergics and Incident Dementia Dementia and Cognitive Impairment JAMA Internal Medicine. Abstract. Importance. Many medications have anticholinergic effects. In general, anticholinergic induced cognitive impairment is considered reversible on discontinuation of anticholinergic therapy. However, a few studies suggest that anticholinergics may be associated with an increased risk for dementia. Objective. To examine whether cumulative anticholinergic use is associated with a higher risk for incident dementia. Design, Setting, and Participants. Prospective population based cohort study using data from the Adult Changes in Thought study in Group Health, an integrated health care delivery system in Seattle, Washington. We included 3. 43.

Efforts to increase awareness among health care professionals and older adults about this potential medication related risk are important to minimize anticholinergic use over time. Introduction. Medications with anticholinergic activity are used widely by older adults for diverse conditions, such as overactive bladder, seasonal allergies, and depression. Some anticholinergics achieve the intended therapeutic outcome by blocking the effect of acetylcholine at the muscarinic receptor within specific organ systems eg, antispasmodics for the gastrointestinal tract, antimuscarinics for the bladder, and antiparkinsonians. However, other medications have unintended anticholinergic effects that are not the primary therapeutic activity eg, first generation antihistamines, tricyclic antidepressants, and certain antipsychotics. The prevalence of anticholinergic use in older adults ranges from 8 to 3. This frequent use is despite the conclusions of professional organizations that the benefits of using these agents in older adults may be outweighed by the risks. A well known risk with anticholinergics is acute impairment in specific aspects of cognition eg, working memory, attention, and psychomotor speed, which has been demonstrated in single dose experimental studies. In addition, anticholinergics may be associated with global cognitive impairment. Older adults may be more sensitive to anticholinergic effects in the central nervous system because of age related changes in pharmacokinetics and pharmacodynamics, reduced acetylcholine mediated transmission in the brain, and increased permeability of the blood brain barrier. The general view is that anticholinergic induced cognitive impairment is reversible on discontinuation of medication therapy. However, several investigators. One biologically plausible mechanism for these findings is that cumulative use of these agents results in pathologic changes in the brain similar to those observed with Alzheimer disease AD. These observational studies have 4 important limitations. First, current anticholinergic use was ascertained at study entry and periodically during follow up only by conducting a medication inventory. Second, these studies lacked information about the dose and duration of anticholinergic use. Third, these studies had short follow up periods. This last point is important because the pathophysiological changes in the brains of patients with AD require several years to occur. Finally, these studies did not take into account that certain anticholinergics are used to manage insomnia and depression, 2 prodromal conditions that can be seen in early but undiagnosed dementia, leading to protopathic bias.

In this situation, the association between anticholinergics and dementia would not be causal but would arise because anticholinergics are used to treat early eg, prodromal symptoms of dementia. Given the potentially enormous public health implications, a better understanding of the possible risks of cumulative anticholinergic use is needed. The objective of this study was to examine the association between 1. We hypothesized that greater cumulative use of anticholinergics would be associated with increased risk. Serial Code For The Sims 3 Computer. Methods. Design, Study Setting, and Participants. The research protocol for this population based prospective cohort study was reviewed and approved by the institutional review boards of Group Health GH and the University of Washington, Seattle. Participants provided written informed consent. Group Health is an integrated health care delivery system in the northwestern United States. Participants were from the Adult Changes in Thought ACT study, and details about study procedures have been detailed elsewhere. Briefly, study participants 6. Seattle area GH members. Participants with dementia were excluded. The original cohort of 2. An additional 8. 11 participants were enrolled from 2. In 2. 00. 4, the study began continuous enrollment to replace those who died or dropped out. Participants underwent assessment at study entry and returned biennially to evaluate cognitive function and collect demographic characteristics, medical history, health behaviors, and health status. The present study sample was limited to participants with at least 1. GH health care plan enrollment before study entry to permit sufficient and equal ascertainment of cumulative anticholinergic exposure. The study sample was further limited to those with at least 1 follow up study visit, which is necessary to detect incident dementia. Of the 4. 72. 4 participants enrolled in the ACT study, 3. GH data for research, 6. GH enrollment, and 6. Data through September 3. Identification of Dementia and AD. We used the Cognitive Abilities Screening Instrument to screen for dementia at study entry and each biennial study visit. The Cognitive Abilities Screening Instrument scores range from 0 to 1. Participants with scores of 8. The results of these evaluations and laboratory testing, along with clinical data from the participants medical records, were then reviewed in a multidisciplinary consensus conference. The diagnoses of dementia and AD were made using research based criteria.
