Causes of Memory Loss and Other Related Problems

Alzheimer's disease 

Sometimes I forget things. Should I be concerned?

Everyone forgets things. How many times have you lost your car keys or forgotten the name of a person you just met?

Forgetfulness tends to increase with age, but there's a big difference between normal absent-mindedness and the type of memory loss associated with Alzheimer's disease.

Normal aging and memory loss

Normal age-related memory loss doesn't prevent you from living a full and productive life. You just need more time to remember a name or make lists of things you plan to do. You're aware that you're forgetful and may even joke about it.

People with memory loss due to something other than normal aging may feel that something's not quite right, but they're unable to pinpoint what's bothering them. Rather than call attention to a memory lapse, they may become more withdrawn or try to hide their mistakes.

Alzheimer's disease and memory loss

Memory loss associated with Alzheimer's disease gets worse over time, but it certainly isn't the only symptom of the disease. Some of the earliest signs and symptoms of Alzheimer's disease include:

• Asking the same questions over and over.
• Difficulty remembering common words when speaking.
• Mixing up words — saying "bed" instead of "table," for example.
• Being unable to complete familiar tasks, such as following a recipe.

Other early signs include:

• Misplacing items and putting them in the wrong places, such as putting a wallet in the refrigerator.
• Getting lost on familiar streets.
• Going through sudden changes in mood or behavior for no clear reason.
• Becoming less able to follow directions.

Causes of memory loss that can be reversed

Many other medical problems cause symptoms similar to Alzheimer's. That's why it's so important to consult a doctor if you've noticed memory failures or unusual mood swings in yourself or in someone close to you. Possible causes of reversible memory loss include:

Medications

Sometimes, a single medication causes side effects similar to Alzheimer's disease symptoms. Drug interactions, which sometimes occur in people taking a number of medications, can also cause confusion and forgetfulness. Medications that can affect your memory include:

• Pain medication
• Blood pressure medications
• Sedatives

Be sure to give your doctor a list of all medications you use, including herbal remedies and over-the-counter items.
