Significant dehydration can be a sign of potential neglect in the long-term care setting. Dehydration is accompanied by the disturbance in the balance of essential electrolytes, particularly sodium, potassium and chloride.

The prevalence of clinically significant symptoms of depression ranges from 8% o 15% for elders in community settings and about 30% for the institutionalized elderly. Not surprisingly, the elderly in nursing homes are vulnerable to depression especially during the initial admission when they are undergoing a significant change from their prior environment. A nursing home should do a complete assessment of the resident’s mental status which should include consideration of potential depression and related issues.
Dermis: The layer of the skin just below the epidermis consisting of papillary and reticular layers and further containing blood and lymphatic vessels, nerves and nerve endings.

Diabetes can be caused by a deficiency of anti-diuretic hormone (ADH) as in diabetes insipidis or it may be the polyuria resulting from the hypoglycemia that occurs in diabetes mellitis. Diabetes mellitis is primarily a result of a deficiency or lack of insulin secretion by the pancreas and/or resistance to insulin. The disease is often familial but can be acquired, as in Cushing's syndrome. Early identification and treatment of diabetes is essential to the health of our elderly population. The goal of treatment is to maintain insulin glucose homeostasis. Type 1 diabetes generally refers to the need to treat the condition with insulin in combination with diet and exercise.

Diverticula are sac-lined mucosal projections through the muscular layer of the GI tract which can cause symptoms by slowing or stopping the flow of feces, or by becoming infected, rupturing or bleeding. Penetration of fecal matter to the thin walled diverticula can cause inflammation and abscess formation in the surrounding tissue, with repeated inflammation, the lumen of the colon narrows and becomes obstructed. Aging typically leads to bowel problems and enemas are sometimes used to rule out carcinoma of the colon. Conservative treatment may include bed rest, IV fluids, antibiotics and abstaining from eating and drinking for a limited period of time.

Edema can be caused by increased capillary fluid pressure, venous obstruction, pressure from casts, tight bandages, congestive heart failure, renal failure, hepatic cirrhosis, inflammatory reactions and other conditions. Edema can also result from loss of serum protein in burns or other significant wounds. Treatment of edema focuses on correcting the underlying cause. Potassium diuretics may be administered to promote excretion of sodium and water.

Elopement: Describes the process in which a resident of a nursing home or other long-term care facility is able to successfully leave the premises without knowledge of the staff. Long term care facilities are required to evaluate residents for their potential risk of elopements and come up with a care plan to prevent such a problem. Many facilities use wander bracelets or other alarms to notify them when a resident has left a secure area. Every year elopements result in serious injuries, especially in situations where the elderly elope into a dangerous environment.

Emphysema: An abnormal condition of the pulmonary system characterized by over inflation and destructive changes in alveolar walls of the lungs. It results in a loss of lung elasticity and decreased gas exchange. Acute emphysema may be caused by a rupture of the alveoli during severe respiratory efforts. Emphysema may also occur after asthma or tuberculosis, conditions in which the lungs are overstretched until the elastic fibers of the alveolar walls are destroyed. In old age the alveolar membranes atrophy and may collapse producing large, air filled spaces and a decrease total surface area of the pulmonary membranes effectively reducing lung capacity.
