Alzheimer's disease is the most common cause of dementia in people over the age of 65. Symptoms include memory loss; impaired judgment and decision-making capacity; a decline in the ability to perform daily living activities; changes in behavior, mood and personality; and increasing dependence on caregivers. A 2007 report released by the Alzheimer's Association estimated there are 5.1 million people in the United States with Alzheimer's disease. And within another generation the number of people with Alzheimer's disease will exceed 15 million. Alzheimer's is a leading cause of death after cardiovascular disease, cancer and cerebrovascular disease. Causes of death in Alzheimer's patients include falls, severe cognitive decline and function impairment, and the development of Parkinsonian signs.
Alzheimer's is the third most expensive disease after cardiovascular disease and cancer in terms of total costs. In the outpatient population, approximately $18,000 is spent per patient, per year for mild Alzheimer's, with increased costs associated with disease progression and severity ($30,000 per patient per year in moderate stage and more than $36,000 per patient per year in the severe stage).
Although age is by far the most important risk factor associated with the onset of Alzheimer's, a number of other risk factors are also important such as female gender, low educational attainment, and head injury (usually associated with a loss of consciousness) appear to increase Alzheimer's risk. Depression, particularly developing in late life, appears to signal the impending onset of Alzheimer's and may precede memory deficits by several years. Family history of dementia in first-degree relatives appears to increase the risk of developing Alzheimer's slightly. Recent evidence suggests that the same risk factors for cardiovascular disease may be important contributors to the risk of developing Alzheimer's. These include high blood pressure, high cholesterol, diabetes, and high homocysteine levels. There are also several genes that are associated with Alzheimer's. This is why it can be hereditary.
The most common symptoms of Alzheimer's include memory impairment such as repetition; trouble remembering recent conversations, events and appointments; frequently misplacing items; decreased ability to solve problems; difficulty with calculations; and impaired driving. Many diseases are associated with memory loss such as hypothyroidism, hypoglycemia, depression, diabetes, chronic inflammation, Wilson's disease, hemochromatosis, B12, vitamin D and antioxidant deficiency, menopause, alcoholism and heavy metal toxicity etc. The list goes on. Also, many drugs can cause memory loss.
It is important to treat memory loss at the early stages and try to identify the cause of the problem. A complete lab work up is necessary to help identify the cause. There are many nutritional and amino acid deficiencies related to memory loss, blood sugar problems, hormonal issues, alcohol, drug and heavy metal toxicity. The list goes on again, which is why a thorough work-up is important. Each patient should be examined individually. Unfortunately the drugs used to treat Alzheimer's are not very effective and tend to have a lot of side effects.
Certain activities - exercise, exposure to classical music, social engagement, playing a musical instrument, reading and bingo - have been associated with improved cognitive function and can prevent the onset of Alzheimer's. The earlier these activities are started in life the better.
Caring for a family member with the disease is very stressful for the care giver. Family caregivers are also at risk for depression, anxiety and physical illness. A caregiver's depression or health decline may affect his or her ability to adequately provide care for the patient and increases the likelihood of premature institutionalization for the patient. Therefore, taking care of the caregiver is just as important as taking care of the patient.
Studies show that Alzheimer's may reach epidemic proportions in 20 years. The goal is to get early diagnosis and treatment for memory loss so one can delay progression of the disease, improve function and reduce caregiver burden. Health problems should not be ignored. Many times they can be treated easily at the early stages of the disease.

Ten years ago I wrote an article for the Vail Daily suggesting that lifestyle changes could impact Alzheimer’s disease. (Click here for the full article). Despite the fact that Alzheimer’s was discovered one hundred years ago, little research had focused on the relationship between the disease and lifestyle. However, a recent study by UCLA researchers shows that lifestyle changes can reverse Alzheimer’s disease. In this small but important study nine out of ten patients who made the required lifestyle changes reversed their memory loss. The only patient who did not improve was a late stage Alzheimer’s patient. Six patients who had to quit their jobs because of memory loss were able to go back to work.
