Understanding behavior in aging has benefited greatly from cognitive neuroscience. Our foundational understanding of the brain in advanced age is based on what now amounts to several decades of work demonstrating differences in brain structure, network organization, and function. Earlier work in this field was focused primarily on the prefrontal cortex and hippocampus. More recent evidence has expanded our understanding of the aging brain to also implicate the cerebellum. Recent frameworks have suggested that the cerebellum may act as scaffolding for cortical function, and there is an emerging literature implicating the structure in Alzheimer's disease. At this juncture, there is evidence highlighting the potential importance of the cerebellum in advanced age, though the field of study is relatively nascent. Here, we provide an overview of key findings in the literature as it stands now and highlight several key future directions for study with respect to the cerebellum in aging.

The prevalence of obesity and osteoporosis (OP) represents a significant public health concern on a global scale. A substantial body of evidence indicates that there is a complex relationship between obesity and OP, with a correlation between the occurrence of OP and obesity. In recent years, sirtuins have emerged as a prominent area of interest in the fields of aging and endocrine metabolism.

Objective: This study examines how age at death, sex, and socio-historical context relate to the frequency, location, and severity of Schmorl's nodes.
Materials: The sample comprised thoracic and lumbar vertebrae of 192 skeletons from two contemporary documented osteological collections from Spain, in Valladolid and Granada, both of which contain individuals who died during the second half of the 20th century.
Methods: Schmorl's nodes were recorded on the superior and inferior surfaces of vertebral bodies and their location was categorized in one of three areas: center, canal, and periphery.
Current and emerging bone resorption inhibitors for the treatment of osteoporosis.

Department of Endocrinology, 424 General Military Hospital, Thessaloniki, Greece.
Introduction: Osteoporosis is a metabolic skeletal disease characterized by low bone mass and strength, and increased risk for fragility fractures. It is a major health issue in aging populations, due to fracture associated increased disability and mortality. Antiresorptive treatments are first line choices in most of the cases.

Age-related changes to the orbicularis oculi muscle include impaired eyelid function, such as lagophthalmos, alterations in tear film dynamics, and aesthetic changes like wrinkles, festoons, and the descent of soft tissue. To date, the structural and functional changes that would comprehensively increase our understanding of orbicularis aging have not been analyzed. This study aims to investigate functional outcomes using surface electromyography and correlate them with ultrastructural changes in orbicularis during aging.
