Diagnosing Alzheimer’s Disease


While there is not one single test used to definitively diagnose Alzheimer’s disease, doctors typically use a variety of tools to make a diagnosis. Along with the person’s primary care provider, specialists like neurologists, neuropsychologists, geriatricians and geriatric psychiatrists may all be involved in determining if the patient’s problems are Alzheimer’s or caused by other reasons.

The process starts with a medical workup done by a health care provider that includes the person’s history of medical problems as well as any history of psychiatric, cognitive or behavioral problems. It is important to tell the doctor about all current medications including over-the-counter-drugs and supplements the person is taking. Your doctor will also want to know if there is a family history of Alzheimer’s or other cognitive problems.

A physical exam should include a check of reflexes, blood pressure levels and questions regarding sleep patterns, diet, exercise and other lifestyle habits. A structural brain imaging scan such an MRI or computed tomography is used to rule out damage to the brain from stroke, tumors, head trauma or a build-up of fluid. Blood and urine tests can rule out other reasons for symptoms. The Alzheimer’s Association says common causes of dementia-like symptoms include depression, untreated sleep apnea, delirium, side effects of medications, thyroid problems, certain vitamin deficiencies and excessive alcohol consumption.

The doctor may also use one of several cognitive, functional tests to evaluate the person’s memory, thinking and simple problem-solving skills. Professionals state, “There is an urgent need for a simple, inexpensive, non-invasive and easily available diagnostic tool such as blood tests to diagnose the disease.” Currently researchers are experimenting with a variety of tests to enable them to track changes more easily in the brain to identify the disease. Currently, health professionals do not recommend routine genetic testing for Alzheimer’s disease.

Be an Active Partner in Your Medical Care

Experts suggest that a good way to reduce medical errors regarding your care or that of a loved one is to be an active partner in the process whether in a hospital setting, doctors’ office or the pharmacy. In fact, a study showed 7% of hospitalized patients experienced an event that was considered preventable which negatively affected their health. Furthermore, harmful errors in primary and outpatient health care settings are typically related to diagnoses, prescriptions and use of medicines. Mistakes associated with misdiagnosis result in delayed treatment for the real problem and having the wrong medications prescribed or supplied can cause serious complications. However, it is important to keep in mind that some medical errors are a result of patients failing to disclose all the medications they take including prescription and over-the-counter drugs. Another problem is the failure to reveal pertinent details regarding a person’s prior medical history as well as lifestyle habits s...

How Many Steps Per Day for Better Health?

  We have all heard about the value of walking 10,000 steps a day but recent studies show it may not actually be the magic number. One study published by JAMA found walking 7,000 steps or more a day may decrease the risk for mortality and offer better overall health. In the cohort study of 2110 adults with a mean follow-up of 10.8 years, participants who walked at least 7000 steps a day, compared with those taking fewer than 7000 steps, had a 50% to 70% lower risk of mortality. Researchers also noted, “There was no association of step intensity with mortality regardless of adjustment for step volume.” A 2020 study found a decreased risk for mortality in participants who took 8,000 steps a day than those who only took 4,000 steps a day. In the same year, another study found more steps taken each day were linked to lower rates of diabetes. Researchers say the bottom line is evidence points to the importance of increased physical activity. Before you begin walking, talk to your health...

Choose a Cozy, Accessible Space The first step in planning a book swap is choosing a comfortable, accessible space. A common room or a cozy corner in senior living Kirkland is ideal.
