Alzheimer's disease (AD) is a debilitating disease influencing a multitude of outcomes, including memory function. Recent work suggests that memory may be influenced by exercise ("memorcise"), even among those with AD. The present narrative review details 1) the underlying mechanisms of AD; 2) whether exercise has a protective effect in preventing AD; 3) the mechanisms through which exercise may help to prevent AD; 4) the mechanisms through which exercise may help attenuate the progression of AD severity among those with existing AD; 5) the effects and mechanisms through which exercise is associated with memory among those with existing AD; and 6) exercise recommendations for those with existing AD...

Femoroacetabular impingement (FAI) is a common cause of hip pain that can affect a wide range of patients. It is due to altered bony morphology of the proximal femur and acetabulum, resulting in decreased function and progression to early osteoarthritis. Until the early 2000s, little was known or understood about the significance of FAI as a clinical entity. The field of hip preservation has grown exponentially since that time, and has led to many advances in caring for those with symptomatic impingement. This review details the early diagnosis and proper management of femoroacetabular impingement for the sports medicine practitioner...
