ABSTRACT
Aging brings about various changes in the brain, leading to cognitive alterations that are increasingly relevant with extended life expectancy. Dementia, characterized by chronic cognitive impairment, is on the rise due to longer life expectancy, imposing a substantial burden on healthcare systems. Dementia encompasses conditions like Alzheimer's disease (AD), vascular dementia (VaD), Lewy body dementia (LBD), and frontotemporal dementia, each with its distinct symptoms and progression. Magnetic resonance imaging (MRI), especially 3T MRI, plays a crucial role in monitoring and diagnosing dementia, aiding in patient selection for emerging therapies. Study involves a comprehensive literature search without restrictions on date, language, age/publication type. Dementia can be divided into neurodegenerative and nondegenerative categories, with AD being the most prevalent. Diagnosis relies on clinical evaluation, supported by neuroimaging techniques like MRI. Various MRI findings, such as cerebral atrophy, microbleeds, white matter hyperintensities, lacunes, and strategic infarcts, offer insights into dementia-related brain changes. These findings facilitate early diagnosis, prognosis, and treatment monitoring, with standardized assessment tools and volumetric analysis enhancing diagnostic accuracy. As life expectancy continues to rise, MRI's role in assessing cognitive impairment changes becomes increasingly vital in addressing the growing challenge of dementia.
ABSTRACT
Open ankle fractures are uncommon (3-6%) among all ankle fractures. Emerging trends show that the incidence of low-energy open ankle fractures is prevalent in older women. The mechanism of open fracture management continues to pose difficulties for orthopaedic surgeons. A simple fall is responsible for just under half of all fractures caused by motor vehicle collisions (MVCs). Despite technological advancements and surgical methods, infectious and non-infectious rates remain problematic. The mainstay of care is to combine antibiotic therapy with thorough irrigation and debridement. To prevent additional soft tissue and vascular damage, these fractures must be stabilized immediately, preferably with an external fixator. When the residual infection has cleared and the soft tissue envelope is adequate, do a definitive open reduction and internal fixation, adapting the procedure to the patient and type of fracture. Functional outcomes could be enhanced by taking safeguards against preventable comorbidities to reduce postoperative complications.
