Shared decision making in mild cognitive impairment.

Shared decision making (SDM) occurs when patients and clinicians consider patients' values and preferences while discussing medical evidence to inform healthcare decisions. SDM enables patients with mild cognitive impairment (MCI) to express values and preferences when making current healthcare decisions and presents a unique opportunity to inform future decision making in the case of further cognitive decline. However, clinicians often fail to facilitate SDM with patients with MCI. This review describes research pertaining to value solicitation, weighing of the medical evidence, and medical decision making for individuals with MCI, explores the role of caregivers, identifies barriers to and facilitators of SDM in MCI, and suggests strategies to optimize SDM for persons with MCI in neurology clinical practice. Further research is needed to identify more strategies for decision support for individuals affected by cognitive impairment.
