In semistructured interviews, only 7% of senior medical students were comfortable assessing behavioral problems associated with dementia. Most were not aware of any validated rating scale to assess neuropsychiatric symptoms. Similarly, only 7% of students were comfortable assessing caregiver burden, and most were not aware of any validated rating scale to assess caregiver burden. Only 1 in 5 students were comfortable using 2 cognitive screens to assess cognitive deficits. Many students stated that they were not routinely expected to perform common cognitive screens, such as the MMSE during their medical training except students who had expressed an interest in psychiatry and were expected to be proficient in the MMSE. Most students were making common mistakes, such as converting the 3-command task to 3 individual single commands, helping too much with serial 7s, and giving too much positive feedback throughout the test.
Discussion
Significant knowledge gaps regarding dementia were found in our study, which is in keeping with other studies in the area. Dementia knowledge deficits among medical trainees have been identified in the United Kingdom, Australia, and the US. 6-9
In our study, a brief multicomponent experiential curriculum improved senior medical students’ perception and self-efficacy in diagnosing dementia. This is in keeping with other studies, such as the PAIRS Program. 7 Findings from another study indicated that education for geriatric- oriented physicians should focus on experiential learning components through observation and interaction with older adults. 16
A background of direct experience with older adults is associated with more positive attitudes toward older adults and increased interest in geriatric medicine. 16 In our study, the exposure was brief; therefore, the results could not be compared with other long-term exposure studies. However, even with this brief intervention most students reported being comfortable with assessing caregiver burden (78%), behavioral problems of dementia (88%), and using ≥ 2 cognitive screens (92%). Comfortable in dementia assessment increased after the intervention from 10% to 96%. This finding is encouraging because brief multicomponent dementia education can be devised easily. This finding needs to be taken with caution because we did not conduct a formal skills evaluation.
A unique component of our experience was to learn medical students’ perception about the impact of neuropsychiatric symptoms on the trajectory, outcomes, and management of dementia. These symptoms included delusions, hallucinations, agitation, depression, anxiety, euphoria, apathy, disinhibition, irritability, motor disturbance, nighttime behaviors, and appetite and eating. Less than half the students thought that neuropsychiatric symptoms had a significant impact on dementia before the experience. Through didactics, systematic assessment of neuropsychiatric symptoms and interaction with caregivers, > 98% of students learned that these symptoms have a significant impact on dementia management.
This experience also emphasized the role of several disciplines in dementia assessment and management. Students’ experience positively influenced appreciation of the role of the memory clinic team. Our hope is that students will seek input from social workers, neuropsychologists, and other team members when working with patients with dementia or their caregivers. The common reason why primary care physicians focus on an exclusive medical model is the time commitment for communicating with an interdisciplinary team. Students experienced the feasibility of the interdisciplinary team involvement and how technology could be used for synchronous and asynchronous communication among team members. Medical students also were introduced to complex billing codes used when ≥ 3 disciplines assess/manage a geriatric patient.
