Speaking of Health: Understanding Alzheimer’s disease

By Dr. Winnie Pao

— As we age, it’s normal to experience occasional forgetfulness and even some confusion. But when you begin to have consistent issues with thinking, reasoning and remembering, it could be a sign of a more serious condition known as dementia.

According to the National Institute on Aging, dementia is the loss of cognitive function and behavioral abilities to the point that it interferes with daily life. The good news is that minor lapses in memory are not typically indicative of dementia.

The most common cause of dementia is Alzheimer’s disease – a condition where brain cells decline in function. Understanding Alzheimer’s will help you to be better prepared as a caregiver, patient or supporter.

What are the signs? Alzheimer’s disease usually begins as mild cognitive impairment, which slowly progresses into serious functional difficulties. The major warning signs for Alzheimer’s include:

1. Memory loss. This is one of the most common symptoms of Alzheimer’s disease. People with Alzheimer’s often:

2. Problems with reasoning and thinking. Individuals with Alzheimer’s often find it increasingly difficult to work with numbers, balance their finances or think abstractly. This may lead to frequently missed bill payments.

3. Changes in behavior. Due to changes in the brain over the course of the disease, Alzheimer’s can cause shifts in behavior and personality including:

4. Disorientation. People with Alzheimer’s may forget the day, month or year. They may also begin to misinterpret their surroundings and become confused as to where they are – and why.

5. Trouble communicating. Those suffering from Alzheimer’s may experience difficulty recalling the correct name of an object. For example, they might call a shovel a “scooping thing.” This cognitive impairment can hinder their ability to express thoughts clearly and may impact social interactions. Occasionally, this is the first sign of Alzheimer’s.

6. Difficulty performing routine activities. As Alzheimer’s progresses, individuals may find it challenging to complete simple, habitual activities, such as following a well-known recipe. Inability to dress or bathe oneself can also appear in later stages of the disease.

7. Poor judgment. A significant decline in decision-making skills is another symptom of Alzheimer’s disease. As a result, people with dementia are especially vulnerable to scams, embezzlement and other forms of financial harm. They may also begin to neglect personal hygiene.

If you notice any of the previously listed symptoms in yourself or a loved one, it’s important to schedule an appointment with your health care provider. Proper and prompt diagnosis is an important first step because other conditions or diseases can also cause dementia.

Can Alzheimer’s be prevented? There is no proven way to prevent Alzheimer’s disease. However, research suggests that certain lifestyles are associated with a lower risk of dementia.

What is the treatment for Alzheimer’s disease? There are several medications used to temporarily slow the progression of Alzheimer’s, but there is not yet a proven treatment for long-term symptom stabilization.

What are the major risk factors? There is still much to be learned about Alzheimer’s disease. Some risk factors linked to Alzheimer’s include:

By maintaining an open dialogue with your health care provider about any concerns or symptoms, you will have the knowledge and the tools to best address the challenges presented by this disease.
