Objective:
The objective of this study was to determine whether chronic use of medications with anticholinergic (AC) properties impact older adults' cognitive functioning.
Methods:
Six years of cognitive test data from two groups of older adults (AC and control) were examined retrospectively (N = 592).
Results:
Declines over time were found for the AC group on parts A and B of the Trail Making Test.
Conclusion:
Physicians prescribing ACs to older adult patients should be aware of their potential effects on psychomotor speed and executive functioning. These cognitive effects may lead to impairments in daily functioning resulting in the need to reevaluate patient medications.

At the neuromuscular junction, these agents work by inhibiting the breakdown of acetylcholine, allowing it to remain bound to the receptor and bind to nearby receptors. This process leads to repetitive firing of the endplate, causing muscle...
