Symptoms of Alzheimer's disease

No one experiences Alzheimer's disease in exactly the same way. As memory loss occurs, it affects cognition, coordination, personality, and standard of living very differently from person to person. However, researchers have identified some patterns in the way the disease progresses, allowing doctors to group Alzheimer's symptoms into three specific stages. This classification can help people to better understand how symptoms might unfold after an Alzheimer's diagnosis and can assist families in making plans for the future.

It's important to keep in mind, though, that while Alzheimer's symptoms have been clustered into stages, there's no way to tell how long any one stage or symptom will last or how quickly others will progress. People with Alzheimer’s die on average about four to six years after their diagnosis, but the disease can also take its relentless toll for as long as 20 years before death occurs.

Alzheimer's Symptoms:

You've forgotten where you've placed your keys. Or you can't remember the name of an actress in a particular movie. Or maybe you are relying more and more on notes to remind yourself you need to do important tasks. Are you suffering from Alzheimer's?

In most cases, the answer is probably not. Most of us experience some “normal” loss of memory, those annoying “senior moments,” as we age. Experts say that misplacing your keys isn’t the issue; forgetting what the keys are used for, however, can be. With this in mind, if you or a loved one is having memory problems that seem to be getting worse more rapidly or happening much more frequently than before, it might be time to pay your doctor a visit.

The following are some early warning signs of Alzheimer's, along with caveats you should keep in mind:

Forgetfulness -  People with early Alzheimer's often find themselves regularly forgetting important information they've just recently learned. On the other hand, there’s probably no need to worry about occasional lapses, such as misplacing your wallet or forgetting names — these types of memory lapses are normal and happen to most people as they get older.

Difficulty completing tasks - People with early Alzheimer's might not be able to remember the steps needed to cook a meal, balance a checkbook, or use a computer program. However, forgetting what you were just going to say or why you went into a particular room isn't unusual when it happens every now and then.

Disorientation - If you've found yourself getting lost in your neighborhood, or ever feel as if you suddenly don't know how to get home because you've forgotten where you are and how you got there, these are signs that could indicate the presence of Alzheimer's. But remember, both of these issues are much different than simply forgetting where you were headed, which can happen to anyone from time to time.

Misplacing objects - Putting objects in strange places — like your car keys in the microwave, or your hair dryer in the washing machine — can be a sign of early Alzheimer's disease. Don't worry if you or your loved one temporarily misplaces keys or a purse, though.

Lapses in judgment - If you notice that you or your loved one has started exhibiting some strange behaviors — like putting on several heavy layers of clothing on a warm day, wearing the same clothes day after day, or giving lots of money away to telemarketers or scam artists, there's reason to suspect Alzheimer's might be present.
