Health Professionals' Views on Standards for Decision-Making Capacity Regarding Refusal of Medical Treatment in Mild Alzheimer's Disease

Background Medical decision-making capacity is impaired in Alzheimer’s disease and mild cognitive impairment. Medical decision-making capacity depends on many different cognitive functions and varies due to situation and cognitive, social, and emotional status of the patient. Our aim was to analyze dementia patients’ capacity to estimate risks and benefits in different clinical trials and determine how cognitive decline affects their attitude toward possible participation and proxy consent. Methods Groups: Alzheimer’s disease (n = 20), mild cognitive impairment (n = 21) and healthy controls (n = 33). Two hypothetical clinical trials, a standardized interview and three visual analogue scales were used to investigate decisions, estimations, reasoning, and attitudes. Results A general positive attitude toward participation in clinical trials was shown among all groups. Both patients and controls motivated possible participation as “own-benefit” in the low-risk trial and to “help-others” in the high-risk trial. Individuals who accepted to participate in the high-risk trial scored lower in medical decision-making capacity in comparison to participants who would not have participated (p < .01). Patients in the Alzheimer’s disease but not mild cognitive impairment and healthy control groups underestimated risks and overestimated benefits in the high-risk/low-benefit trial (p < .05). A family member was most frequently chosen as possible proxy (91%). Conclusions Medical decisions and research consent should be interpreted with caution in patients who are already in early stages of dementia, as the patients’ acceptance to participate in high-risk trials may be due an insufficient decisional capacity and risk analysis, accelerated by a general desire to make good to society. We emphasize the use of a standardized tool to evaluate medical decisional capacity in clinical research.

Testamentary Capacity

Background: Requests for physician-assisted death (PAD) in patients with cognitive impairment are complex and require careful consideration. Of particular difficulty is determination of whether the request is voluntary and well considered. Results: Euthanasia and physician-assisted suicide (PAS) are both legal in The Netherlands, Luxemburg, Colombia, and Canada. Euthanasia is legal in Belgium, while PAS is legal in Switzerland and Oregon, Washington, Montana, Vermont, and California (USA). Upon a PAD request, evaluation of the capacity to consent medical treatment is relevant for the decision-making process, while evaluation of testamentary capacity is appropriate before an advance euthanasia directive is written. Anosognosia assessment throughout the Alzheimer’s disease continuum provides essential and relevant information regarding the voluntary and well-considered nature of the PAD request; meanwhile, early assessment of hypernosognosia or subjective cognitive decline assists in formulation of a clinical prognosis. Furthermore, the assessment of physical and psychological suffering should incorporate verbal and nonverbal cues as well as consideration of the psychosocial factors that might affect due care criteria. Conclusion: The clinical approach to a PAD request should consider the legal framework and the decision-making capacity, assess memory deficit awareness and the perception of suffering, and evaluate mental competency when considered pertinent.

Early Alzheimer’S Disease

Memory awareness in early Alzheimer’s disease (AD) influences capacity to provide informed consent for a memory treatment. This study investigated the extent to which aspects of memory awareness influence everyday decision-making capacity about medication management in AD. 42 participants with mild AD and 50 healthy elders underwent clinical ratings of memory awareness, metamemory testing, and an interview of everyday decision-making capacity regarding medication management. 45% of AD subjects were classified as aware (AAD) and 55% as unaware (UAD) based on clinical ratings and supported by metamemory testing (P=.015). Capacity was impaired in each of the AD groups as compared to the healthy eldersF(2, 67)=17.63, UAD,P<.01; AAD,P=.01). Within the AD group, capacity correlated selectively with awareness as measured with clinical ratings (r=−.41,P=.007) but not objective metamemory testing (r=−.10,P=.60). Appreciation scores were lower in UAD as compared with AADF(1, 35)=8.36,P=.007. Unawareness of memory loss should heighten clinicians’ concern about everyday decision-making capacity in AD.
