There are physiologic changes associated with aging. There are also medical conditions that occur more commonly with advancing age. These changes and conditions increase an older adult’s vulnerability to and injuries from abuse or neglect. An older adult may have more difficulty recovering from an abuse incident. The investigation of abuse or neglect may be more difficult because of aging changes.

Key points
• There are physiologic changes associated with aging.
• There are medical conditions that occur more commonly with advancing age.
• These physiologic changes and medical conditions increase an older adult’s vulnerability to and injuries from abuse or neglect.
• An older adult may have more difficulty recovering from an abuse incident.
• The investigation of abuse or neglect may be more difficult because of aging changes.
With advancing age, an interplay of multiple factors places the older adult at increased risk for abuse and neglect. Consider the following scenario:
A 70-year-old man was brought to the emergency room by paramedics after his daughter called 911 when she found him on the floor in his home without his caregiver. The emergency room doctor reported that the patient was dehydrated and confused; he could not provide his own medical history and did not know the date. You were the admitting physician; you were told that the patient had probably fallen at home. As you examined this patient’s injuries, you began to wonder if the injuries were consistent with a fall. When you met the patient, he was receiving a fluid bolus and was still confused. On review of his chart, you found that he had a history of macular degeneration, hypertension, coronary artery disease, severe arthritis, depression, incontinence, and mild Alzheimer disease. His medications included donepezil, aspirin, clopidogrel, hydrochlorothiazide, metoprolol, and sertraline. On examination, he had multiple bruises along his right shoulder, a large bruise on his left upper arm, and a large confluence of bruises scattered across his chest. There was also an unusual linear pattern bruise on the left side of his chest (Figs. 1 and 2). After seeing him and reviewing the chart, you considered the following questions: were these injuries consistent with the history of a fall? Where was the patient’s caregiver when he fell? Was the severity of the bruising caused by aspirin and clopidogrel? Could these injuries have been caused by physical abuse?

The proportion of the population in the United States that is considered elderly (aged ≥65 years) has increased dramatically in the past 50 years and will continue to do so in the next 50 years as the baby boomers age. According to US Census bureau data, in 2010, 40 million Americans were 65 years or older. This number is expected to increase to more than 80 million by 2050.1 This demographic imperative means that health care providers must understand the medical conditions that occur commonly with age as well as the psychological issues, social factors, and changes in function that may accompany these conditions.
Aging is associated with many physiologic changes that are common to all persons. In addition to these changes, there are medical conditions (diseases) that occur more commonly with age. These changes and conditions increase an older adult’s vulnerability to abuse or neglect.
Overview of aging physiology
As a human body ages, there is a progressive decline in physiologic functioning, which affects all organ systems. These changes place an older adult at increased susceptibility to illness; they also create a disadvantage in recovering from illness. Although these changes are common to everyone, they progress at different rates in each individual and, even in the same person, progress at different rates in each organ system. Table 1 denotes the physiologic changes that can be significant in considering a diagnosis or even a suspicion of elder abuse.

Physiologic changes that occur with normal aging; considerations for elder abuse
System | Physiologic Change | Considerations for Elder Abuse |
Body composition | Increased fat Decreased water and muscle mass | Increased side effects of lipophilic medications |
Skin | Thinning epidermis Decreased elasticity Decreased subdermal fat tissue | Increased bruising, skin tears, pressure sores |
Bone | Decreased bone mineral density Stiffer joints | Increased fragility and fracture risk More prone to musculoskeletal injuries from minor trauma |
Eyes | Decreased tear production Presbyopia Miosis | Increased risk for falls Difficulty reading documents Difficulty identifying abuser |
Ears | Cerumen more tenacious Sensorineural hearing loss | Impaired ability to understand surrounding circumstances Difficulty communicating in investigation |
Cardiovascular | Decreased carotid baroreceptor sensitivity Decreased maximal heart rate Arterial wall stiffness Increased left ventricle thickness | Difficulty recovering from illness/trauma More severe outcome from injuries |
Pulmonary | Increased residual volume Decreased FEV1, vital capacity Weaker respiratory muscles Stiffer chest wall | Increased likelihood of respiratory failure Increased risk for pneumonia |
Muscle | Decreased muscle mass and strength Increased stiffness of tendons and ligaments | Loss of independence Difficulty rising from the floor Difficulty regaining independence after an injury |
Renal | Decreased functioning glomeruli Decreased renal blood flow Glomerular filtration rate declines | Increased susceptibility to medications |
Gastrointestinal | Decreased salivation Slowed esophageal peristalsis Delayed colonic transit time |
Neurologic | Decreased white matter Loss of synapses Mild cognitive changes Decreased proprioception and vibratory sense | Slower information processing Balance problems Increased risk for falls |
Reproductive | Vaginal atrophy Narrowing of the vaginal introitus | Increased risk for injury from sexual assault More difficult sexual assault examination |
Body Composition
From young adulthood to old age, the percentage of body fat increases from 15% to 30%. This increase is accompanied by a decrease in muscle mass, total body water, and bone mass. These changes are important when considering the metabolism of medications and are part of the reason that some medications (eg, benzodiazepines) are more dangerous in older adults than younger adults.
Skin
Skin is an important organ, which provides a protective, thermoregulatory, and sensory function. The effects of aging on the skin can be divided into intrinsic and extrinsic changes.2 The epidermal cells have a slower turnover rate, causing thinning of the epidermis. This thinner epidermis also has fewer melanocytes and Langerhans cells, decreasing the barrier and immune function of the skin and increasing risk for sunburn and cancer. In the dermis, there is a decrease in fibroblasts, collagen, and elastin, causing skin wrinkling and a loss of elasticity. A diminution of subdermal fat tissue in combination with capillary fragility leaves an elder more prone to bruising from seemingly minor trauma. In addition, several medications and conditions could increase an older adult’s risk for bruising. For example, aspirin, clopidogrel, and warfarin may increase bleeding time and propensity for bruising. Diseases such as cirrhosis or myelodysplasia could cause disruptions in the clotting mechanism and predispose to bruising or bleeding. Chronic sun exposure, the predominant extrinsic factor in age-related changes, contributes to wrinkling and loss of tone in the skin.
Bone
With aging, there are changes in the architecture of both trabecular and cortical bone, as well as changes in the bone marrow. There is a reduction in trabecular and cortical bone volume, caused by an imbalance between bone formation and resorption. There is also an increase in adiposity of the bone marrow.3 These changes...
