Early Diagnosis of Dementia - Article
ABSTRACT: Until recently, the most significant issue facing a family physician regarding the diagnosis and treatment of dementia was ruling out delirium and potentially treatable etiologies. However, as more treatment options become available, it will become increasingly important to diagnose dementia early. Dementia may be suspected if memory deficits are exhibited during the medical history and physical examination. Information from the patient's family members, friends and caregivers may also point to signs of dementia. Distinguishing among age-related cognitive decline, mild cognitive impairment and Alzheimer's disease may be difficult and requires evaluation of cognitive and functional status. Careful medical evaluation to exclude treatable causes of cognitive impairment is important. Patients with early dementia may benefit from formal neuropsychologic testing to aid in medical and social decision-making. Follow-up by the patient's family physician is appropriate in most patients. However, a subspecialist may be helpful in the diagnosis and management of patients with dementia with an unusual presentation or following an atypical course.
Anemia in Children - Article
ABSTRACT: Anemia in children is commonly encountered by the family physician. Multiple causes exist, but with a thorough history, a physical examination and limited laboratory evaluation a specific diagnosis can usually be established. The use of the mean corpuscular volume to classify the anemia as microcytic, normocytic or macrocytic is a standard diagnostic approach. The most common form of microcytic anemia is iron deficiency caused by reduced dietary intake. It is easily treatable with supplemental iron and early intervention may prevent later loss of cognitive function. Less common causes of microcytosis are thalassemia and lead poisoning. Normocytic anemia has many causes, making the diagnosis more difficult. The reticulocyte count will help narrow the differential diagnosis; however, additional testing may be necessary to rule out hemolysis, hemoglobinopathies, membrane defects and enzymopathies. Macrocytic anemia may be caused by a deficiency of folic acid and/or vitamin B12, hypothyroidism and liver disease. This form of anemia is uncommon in children.
Diagnosis and Treatment of Osteoporosis - Article
ABSTRACT: Osteoporosis affects approximately 8 million women and 2 million men in the United States. The associated fractures are a common and preventable cause of morbidity and mortality in up to 50 percent of older women. The U.S. Preventive Services Task Force recommends using dual energy x-ray absorptiometry to screen all women 65 years and older and women 60 to 64 years of age who have increased fracture risk. Some organizations recommend considering screening in all men 70 years and older. For persons with osteoporosis diagnosed by dual energy x-ray absorptiometry or previous fragility fracture, effective first-line treatment consists of fall prevention, adequate intake of calcium (at least 1,200 mg per day) and vitamin D (at least 700 to 800 IU per day), and treatment with a bisphosphonate. Raloxifene, calcitonin, teriparatide, or hormone therapy maybe considered for certain subsets of patients.
Mild Cognitive Impairment in the Elderly - Editorials
ABSTRACT: Gait and balance disorders are common in older adults and are a major cause of falls in this population. They are associated with increased morbidity and mortality, as well as reduced level of function. Common causes include arthritis and orthostatic hypotension; however, most gait and balance disorders involve multiple contributing factors. Most changes in gait are related to underlying medical conditions and should not be considered an inevitable consequence of aging. Physicians caring for older patients should ask at least annually about falls, and should ask about or examine for difficulties with gait and balance at least once. For older adults who report a fall, physicians should ask about difficulties with gait and balance, and should observe for any gait or balance dysfunctions. The Timed Up and Go test is a fast and reliable diagnostic tool. Persons who have difficulty or demonstrate unsteadiness performing the Timed Up and Go test require further assessment, usually with a physical therapist, to help elucidate gait impairments and related functional limitations. The most effective strategy for falls prevention involves a multifactorial evaluation followed by targeted interventions for identified contributing factors. Evidence on the effectiveness of interventions for gait and balance disorders is limited because of the lack of standardized outcome measures determining gait and balance abilities. However, effective options for patients with gait and balance disorders include exercise and physical therapy. (Am Fam Physician. 2010;82(1):61-68.

Health Screening in Older Women - Article
ABSTRACT: Health screening is an important aspect of health promotion and disease prevention in women over 65 years of age. Screening efforts should address conditions that cause significant morbidity and mortality in this age group. In addition to screening for cardiovascular disease, cerebrovascular disease and cancer, primary care physicians should identify risk factors unique to an aging population. These factors include hearing and vision loss, dysmobility or functional impairment, osteoporosis, cognitive and affective disorders, urinary incontinence and domestic violence. Although screening for many conditions cannot be proved to merit an "A" recommendation (indicating conclusive proof of benefit), special attention to these factors can decrease morbidity and improve quality of life in aging women.
