Alzheimer´s disease (AD) is a neurodegenerative disorder that accounts for 50-75% cases of dementia in the elderly. It is characterized by high morbidity (mainly memory loss) and a scarcity of treatments to revert disease progression. As reported by Alzheimer's Disease International 2015 report, 46 million people worldwide suffer from this disease, with an estimated total cost of U$S 818 billion. Osteoporosis (OS) is defined as a decrease in bone density with compromised bone resistance and increased fracture risk. OS is a degenerative disorder that mainly affects the elderly, showing high morbidity and mortality due to osteoporotic fractures. Recent studies have found that there is an increase in the incidence of OS and hip fractures in patients with AD, compared to control (non-AD) individuals. On the other hand, it has been demonstrated that there is an increased prevalence of AD in women with OS. Thus, in ageing individuals there appears to be a bidirectional association between AD and OS.
