Vitamin D and Its Analogues: From Differences in Molecular Mechanisms to Potential Benefits of Adapted Use in the Treatment of Alzheimer’s Disease
Lifestyle habits and insufficient sunlight exposure lead to a high prevalence of vitamin
D hypovitaminosis, especially in the elderly. Recent studies suggest that in central Europe more
than 50% of people over 60 years are not sufficiently supplied with vitamin D. Since vitamin D
hypovitaminosis is associated with many diseases, such as Alzheimer’s disease (AD), vitamin D
supplementation seems to be particularly useful for this vulnerable age population. Importantly, in
addition to vitamin D, several analogues are known and used for different medical purposes. These
vitamin D analogues differ not only in their pharmacokinetics and binding affinity to the vitamin D
receptor, but also in their potential side effects. Here, we discuss these aspects, especially those of the
commonly used vitamin D analogues alfacalcidol, paricalcitol, doxercalciferol, tacalcitol, calcipotriol,
and eldecalcitol. In addition to their pleiotropic effects on mechanisms relevant to AD, potential
effects of vitamin D analogues on comorbidities common in the context of geriatric diseases are
summarized. AD is defined as a complex neurodegenerative disease of the central nervous system and
is commonly represented in the elderly population. It is usually caused by extracellular accumulation
of amyloidogenic plaques, consisting of amyloid (Aβ) peptides. Furthermore, the formation of
intracellular neurofibrillary tangles involving hyperphosphorylated tau proteins contributes to the
pathology of AD. In conclusion, this review emphasizes the importance of an adequate vitamin D
supply and discusses the specifics of administering various vitamin D analogues compared with
vitamin D in geriatric patients, especially those suffering from AD
Interprofessional education: a necessity in Alzheimer’s dementia care—a pilot study
Introduction: Interprofessional collaboration is seen as an indispensable
prerequisite for high-quality health services and patient care, especially for
complex diseases such as dementia. Thus, the current project aimed to extend
interprofessional and competency-based education in the field of dementia care
to the previously understudied therapy professions of nutrition, speech-language
pathology, and physiotherapy.
Methods: A three-day workshop was designed to provide specific learning
objectives related to patient-centered dementia care, as well as competences
for interprofessional collaboration. Teaching and learning approaches included
case-based learning in simulated interprofessional case-conferences and peerteaching. A total of 42 students (n  =  20 nutrition therapy and counseling, n  =  8
speech-language pathology, n  =  14 physiotherapy), ranging from first to seventh
semester, finished the whole workshop and were considered in data analysis.
Changes in self-perceived attitudes toward interprofessional collaboration and
education were measured by the German version of the UWE-IP. An in-house
questionnaire was developed to evaluate knowledge and skills in the field of
dementia, dementia management and interprofessional collaboration.
Results: Participation in the workshop led to significant improvements in the total
scores of the UWE-IP-D and the in-house questionnaire, as well as their respective
subscales. Moderate to large effect sizes were achieved. All professions improved
significantly in both questionnaires with large effect sizes. Significant differences
between professions were found in the UWE-IP-D total score between students of
speech-language pathology and physiotherapy in the posttest. Students of nutrition
therapy and counseling revealed a significant lower level of self-perceived knowledge
and skills in the in-house questionnaire pre- and post-testing.
Discussion: The pilot-study confirms the effectiveness of interprofessional
education to promote generic and interprofessional dementia care competencies
and to develop positive attitudes toward interprofessional learning and
collaboration in the therapy professions, thus increasing professional diversity
in interprofessional education research. Differences between professions were
confounded by heterogenous semester numbers and participation conditions.
To achieve a curricular implementation, interprofessional education should
be expanded to include a larger group of participants belonging to different
professions, start early in the study program, and be evaluated over the long term
