Significant improvements in aerobic capacity and treadmill time to exhaustion can be obtained in older adults as a consequence of either high- or low-intensity resistance exercise. These findings suggest that increased strength, as a consequence of resistance exercise training, may allow older adults to reach and/or improve their aerobic capacity.

Some chronic medical conditions are associated with a greater likelihood of receiving adequate depression care; comorbid medical conditions do not result in lower quality of depression treatment in older persons. The high prevalence rates of comorbid depression and low rates of adequate depression care in elderly persons with chronic illnesses point to the importance of improving primary care depression treatment or enhancing specialty mental health referral.

The aging process, behavioural habits and a multitude of pathological conditions are the main contributors to the development of nocturia in the elderly. Age-related physiological changes can alter the regular pattern of urine excretion and lead to increased nocturnal frequency of voiding. In addition, aging is associated with anatomical and physiological changes of the urinary tract itself that predispose to increased urinary frequency without affecting urine volume. Several urinary and extra-urinary tract conditions may have nocturia as a prominent symptom. These conditions can be grouped as those associated with bladder overactivity, bladder outlet obstruction, bladder hypotonicity and an increased urine volume. A detailed assessment that gathers clues from the medical history, physical examination and laboratory is of utmost importance in identifying the specific causes. Overactive bladder can be idiopathic or associated with different triggers such as UTI, bladder stones, bladder tumours and CNS diseases that disrupt the normal inhibitory signals to the bladder. It may be cured by the successful elimination of the trigger conditions. Therapeutic modalities include behavioural therapies with scheduled voiding, anticholinergic drugs and in women the use of transvaginal electrical stimulation. Benign prostatic hyperplasia is the most common cause of bladder outlet obstruction in men. Different drug classes (e.g. peripheral alpha-adrenoceptor blockers and 5 alpha-reductase inhibitors) are now available for the treatment of mild to moderate symptoms. Surgery is reserved for patients with severe symptoms or with complications, with new and less invasive surgical techniques being preferred. Bladder hypotonicity is usually caused by peripheral neuropathies, spinal cord lesions and the indiscriminate use of drugs with anticholinergic actions. Treatment involves discontinuation of implicated drugs, short term use of cholinergic drugs and urinary catheterisation. Increased urine volumes and nocturia are frequently seen in hyperosmolar and oedematous states. Excessive ingestion of fluids, caffeinated or alcoholic beverages are habits that commonly produce nocturia. Although more definitive studies are awaited, low dose loop diuretics given a few hours prior to bedtime and desmopressin nasal spray or tablets may be useful alternatives for the control of nocturic symptoms in elderly patients with nocturnal polyuria syndrome. Whenever nocturia is present, clinicians should try to identify its causes by means of a thorough history, physical examination and pertinent complimentary tests. Once the specific cause or causes are found, most cases can be satisfactorily managed with behavioural, pharmacological or surgical therapies.

Aging is the primary risk factor for functional decline; thus, understanding and preventing disability among older adults has emerged as an important public health challenge of the 21st century. The science of gerontology – or geroscience - has the practical purpose of “adding life to the years.” The overall goal of geroscience is to increase healthspan, which refers to extending the portion of the lifespan in which the individual experiences enjoyment, satisfaction, and wellness. An important facet of this goal is preserving mobility, defined as the ability to move independently. Despite this clear purpose, this has proven to be a challenging endeavor as mobility and function in later life are influenced by a complex interaction of factors across multiple domains. Moreover, findings over the past decade have highlighted the complexity of walking and how targeting multiple systems, including the brain and sensory organs, as well as the environment in which a person lives, can have a dramatic effect on an older person's mobility and function. For these reasons, behavioral interventions that incorporate complex walking tasks and other activities of daily living appear to be especially helpful for improving mobility function. Other pharmaceutical interventions, such as oxytocin, and complementary and alternative interventions, such as massage therapy, may enhance physical function both through direct effects on biological mechanisms related to mobility, as well as indirectly through modulation of cognitive and socioemotional processes. Thus, the purpose of the present review is to describe evolving interventional approaches to enhance mobility and maintain healthspan in the growing population of older adults in the United States and countries throughout the world. Such interventions are likely to be greatly assisted by technological advances and the widespread adoption of virtual communications during and after the COVID-19 era.
