Chances are you’ve walked into a room and suddenly forgotten what you were looking for. Or perhaps during a conversation, a certain word eluded you. Those episodes, often dubbed “senior moments,” are generally just temporary lapses in memory, but dementia testing can help discern whether it’s something more.
“If we compare people in their 20s with older people, the younger people will almost always do better on memory tests,” explains neurologist Edmond Teng, MD, David Geffen School of Medicine at UCLA. “Much of what we call ‘senior moments’ might be more attention- or focus-related, or it could be processing speed. Information just can’t be processed as fast as it used to be.”
Symptoms of Something More
Trying to discern what is normal age-related forgetfulness versus something more serious is not always a black-and-white issue. Small lapses in memory are generally no big deal. For example, not being able to recall a person’s name upon seeing them but then recalling that name later is less likely to be of concern.
“The people who later remember things they’ve forgotten are more likely to be experiencing normal age-related memory changes,” says Dr. Teng. “It’s the people who don’t remember that they have forgotten things. That’s when our level of suspicion goes up.”
Other instances that raise concern include:
- Repetitive questioning within a short period of time
- Getting lost on familiar routes
- Memory loss that affects daily function
- Falling for similar financial scams multiple times
Common Dementia Testing Options
If you or a loved one experiences some of the above situations, the first step is to see a primary care doctor or a geriatric physician. That physician will typically do a short cognitive screening test before deciding whether to refer you to a specialist for more extensive memory and/or dementia testing.
A common test called the Mini Cog includes comprehension and recall. The patient is asked to draw a circle for a clock and to place the hands to reflect a specific time, such as 10 minutes after eleven. For recall, the physician asks the patient to remember three unrelated words, such as chair, pineapple, and dust. Later, during the exam, the physician will ask for those words to be recalled.
The Mini-Mental State Exam, MMSE, is another commonly used assessment. It is a quick way to evaluate language function, attention, speed of processing, visual and visual-spatial contexts, and executive function. The test takes about 10 minutes. Like the Mini Cog, the MMSE does not diagnose a specific underlying disease, but it can indicate if there are cognitive problems that warrant further investigation.
The MMSE consists of a series of questions and tests. For example:
- Orientation: What is today’s date and season?
- Attention and calculation: Count backwards from 100 by 7s.
- Language: Look at a pencil and state out loud what it is.
If these short exams suggest a potential problem, the physician may refer a patient to a specialist for further evaluation.
Experts Who Diagnose and Treat Memory Problems
Neurologists are medical doctors who specialize in diseases of the brain, spinal cord, and nerves. They are often consulted for neurological and memory problems related to such diseases as Parkinson’s, multiple sclerosis, and Alzheimer’s. Neurologists have expertise in various regions of the brain, and the roles those regions play in physical and mental functioning.
Geriatric psychiatrists are also medical doctors. They specialize in distinguishing between physical and psychological causes of disorders in older adults. They are experts at dealing with memory problems that involve psychiatric issues, such as major depression, anxiety, agitation, or delusions.
Geriatric psychologists hold PhD degrees in psychology and specialize in psychological assessments and treatment of mental and nervous disorders in older adults. They focus on memory, competency, depression, and adjustment disorders, such as grieving the death of a loved one. Through testing and therapy, they can help patients with various psychological problems, including those associated with memory loss.
Tests with these experts are more comprehensive, requiring about an hour and a half, and possibly multiple visits. The tests may include neuropsychological assessments (paper-based and conversational) to evaluate memory and various aspects of thinking. Diagnostic tests may also be ordered, such as blood tests, MRIs and CT scans. Some medical illnesses (and medications) can impact a person’s memory and cognitive function. That’s why multiple tests may be needed to identify the causes of the symptoms.
WHAT YOU SHOULD KNOW
According to the Alzheimer’s Association, the following can help you distinguish an ordinary age-related change from a sign of Alzheimer’s.
Signs of Alzheimer’s…vs. Typical Age-Related Changes
- Poor judgment and decision making…vs. Making a bad decision once in a while
- Inability to manage a budget…vs. Missing a monthly payment
- Losing track of the date or the season…vs. Forgetting which day it is but remembering later
- Difficulty having a conversation…vs. Sometimes forgetting which word to use
- Misplacing things and being unable to retrace steps to find them…vs. Losing things from time to time
