Abstract
IntroductionAlzheimer’s disease is associated with low bone mineral density. Various studies have linked early-onset Alzheimer's disease with bone health. In this study, we will determine the association between bone health and recently diagnosed Alzheimer's disease in the local population.MethodsThis case-control study was conducted at the neurology unit from April 2019 to Sept 2019. One hundred and fifty (150) Alzheimer’s patients with recently (within the last six months) confirmed diagnoses, based on clinical symptoms, mental status, and computed tomography (CT) scan, were included from the neurology outpatient department. The gender and age-matched 150 healthy participants were included in the study as the reference group. Various parameters of bone health and mental status were measured.ResultsParticipants with Alzheimer’s had a significantly lower level of serum vitamin D (15.2 ± 4.2 ng/mL vs. 27.5 ± 8.1 ng/mL, p-value: < 0.0001) and lower level of serum osteocalcin (4.3 ± 1.7 ng/L vs. 5.6 ± 2.0 ng/L, p-value: < 0.0001). Participants with Alzheimer’s disease had more people with T-score ≤ -2.5 as compared to the general population (52.0% vs. 16.6%, p-value <0.0001).ConclusionAlzheimer’s disease is associated with poor bone health as compared to the general population of the same age. Bone health can be an important parameter to screen patients at risk of Alzheimer’s disease. The management of Alzheimer’s disease should include a regular assessment of bone health, and the treatment plan should include therapies to improve bone health.
