13 Signs You Could Have Early-Onset Alzheimer’s Disease
Early-onset Alzheimer’s disease strikes people younger than age 65, with symptoms usually starting to show when people are in their 40s or 50s. Here are the signs to watch for.
You’re extremely forgetful
Memory loss is the most common symptom of early-onset Alzheimer’s disease (and late-onset as well), which occurs before the age of 65, according to the Mayo Clinic. It’s typically one of the first signs that something is wrong. Symptoms of early-onset Alzheimer’s—which are similar to those that appear in other cases of the condition—usually start when people are in their 40s or 50s, but memory loss is also a normal part of aging.
“We don’t want to worry people that when they can’t remember a name or a word, that they’re on their way to Alzheimer’s,” says Rudolph Tanzi, PhD, professor of neurology at Harvard Medical School and director of Massachusetts General Hospital’s Genetics and Aging Research Unit. “As we get older, our brain isn’t as good. Wear and tear, and inflammation, affect the brain much like it affects our joints.”
According to the Alzheimer’s Society of Canada, memory issues that reflect normal aging include things like not being able to remember details of a conversation or event that took place a year ago, or not being able to remember the name of an acquaintance. But signs of a cognitive problem might be not being able to recall details of recent events or conversations, or not recognizing or knowing the names of family members.

You’re misplacing things—all the time
Everyone misplaces things from time to time—cell phone, glasses, keys. The difference in people who might have early-onset Alzheimer’s or another cognitive problem is that these losses happen more frequently, and they’re unable to retrace their steps or think of where to look for the lost item. According to the Mayo Clinic, people with Alzheimer’s “may routinely misplace possessions, often putting them in illogical locations.” So if your car keys are in your other purse, it’s probably no big deal. But if they turn up in the refrigerator, it could be cause for concern. Try these 15 memory exercises proven to keep your brain sharp.
People with early-onset Alzheimer’s (or late-onset) may repeat statements and questions over and over, not realizing that they’ve asked the same question before, according to the Mayo Clinic. “The time to get worried,” says Elise Caccappolo, PhD, associate professor of neuropsychology at Columbia University Medical Center, “is when people repeat themselves within a very short time span.” An example would be if someone asks when a friend is coming to visit, gets told the answer, and then asks the same question a few minutes later without remembering that he or she had already inquired.

Your sleep habits change
Many people with Alzheimer’s have difficulty sleeping, waking up more often and staying awake longer during the night, according to the Alzheimer’s Association. Changes in sleep that might indicate early-onset Alzheimer’s include daytime napping and/or feeling drowsy during the day but being unable to sleep at night. Learn more about unexpected reasons for insomnia.
You have trouble completing everyday tasks
“As a general rule, what I tell people is that as we age, many of us will experience the phenomenon of slower processing speed,” explains Pierre Tariot, MD, director of the Banner Alzheimer’s Institute in Phoenix, Arizona. “We can’t manage complex intellectual challenges as quickly as we did in our youth.” Multitasking may become more difficult, doing mathematical calculations in your head may take more time, and balancing your checkbook will be a bit slower than it used to be. But according to the Fisher Center for Alzheimer’s Research Foundation, someone with early dementia may find it impossible to do everyday tasks—like balancing a checkbook—that once were easy. If someone used to be a gourmet cook and now has difficulty following a complex recipe, that can be a red flag, too. Find out 16 things people with Alzheimer’s wish you knew.
You feel confused
All of us occasionally forget an appointment, get lost when going somewhere new, or briefly think it’s Tuesday when actually it’s Wednesday. But a possible sign of early-onset Alzheimer’s disease is, say, forgetting the route to the supermarket where you shop weekly. According to the Alzheimer’s Association, people with the disease may have trouble understanding something if it isn’t happening immediately, and may sometimes forget where they are or how they got there. “You shouldn’t have confusion about where you are or what day it is from normal aging,” says Caccappolo.
Feeling depressed, or a personality shift

Approximately 7 percent of the general population suffers from depression, but between 40 and 50 percent of people with Alzheimer’s experience it, experts at Johns Hopkins University say: “People with Alzheimer’s who are depressed tend to be apathetic and irritable and to have sleep disturbances, but they are less likely to feel guilty or have a risk of suicide than depressed people without Alzheimer’s.” Other changes in personality that might indicate early-onset Alzheimer’s include mood swings, anxiety, aggression, anger, fear, suspicion, and loss of inhibitions.

Making poor decisions
Nobody is perfect, and we all make bad choices on occasion (remember that perm?). But people with early-onset Alzheimer’s may have poor judgment and start making bad decisions with greater consequences. They may spend money indiscriminately or even give it away; they could stop taking care of themselves (not showering regularly, for example). According to the Mayo Clinic, people with Alzheimer’s may not be able to respond effectively to everyday problems like food burning on the stove or a challenging traffic situation.

Trouble speaking or writing clearly
People with signs of early-onset Alzheimer’s disease may have trouble participating in a conversation or writing down their thoughts. According to Medical News Today, “The person may stop in the middle of a conversation, unable to figure out what to say next. They may struggle to find the right word or label things incorrectly.” Most people will occasionally pause to search for the right word and eventually remember it. But someone with signs of early-onset Alzheimer’s disease may experience the problem frequently, substitute an inappropriate word for the one they can’t remember, or be unable to continue speaking because they don’t know what to say. Don’t fall for these 15 myths about Alzheimer’s.
Losing interest in work and socializing
It’s normal to want to try to balance work and social life, to wish you could spend more time with your family or work fewer hours. But withdrawing from work projects or social activities you used to enjoy—for instance, losing interest in a sports team you once followed religiously—could be a sign of early-onset Alzheimer’s disease; so can feeling apathetic and losing interest in once-favorite hobbies. “[W]hile many of us plop down on the couch to watch TV after a long day of work, someone with dementia may show little or no initiative in reaching out to friends and stare at the TV for hours or sleep all day,” according to the Fisher Center. Check out 5 expert-approved habits that can help prevent Alzheimer’s.
Struggling with your vision
Nearly everyone needs reading glasses after age 40, but people with early-onset Alzheimer’s disease may suffer from different vision problems that can include difficulty distinguishing contrast and colors or difficulty judging distances between objects. “These vision problems combined can make it difficult or impossible to drive,” according to Medical News Today. That’s why it’s so important to get regular eye checkups.
Friends and relatives are concerned

People with early-onset Alzheimer’s disease may not recognize their decline—but those closest to them could notice changes. “If a loved one expresses concern, says that you seem really different, is worried that something is going on, that’s a legitimate basis for a medical evaluation,” says Dr. Tariot. Don’t dismiss these concerns, since they may be the key to getting an early diagnosis, along with early treatment that perhaps can slow the progression of cognitive changes. Check out the 6 Alzheimer’s breakthroughs that are bringing hope for the future.
You have a family history of early-onset Alzheimer’s
This is the biggest risk factor. “Early-onset Alzheimer’s disease has a very strong genetic component,” explains Stephen Rao, PhD, a neuropsychologist at the Cleveland Clinic’s Lou Ruvo Center for Brain Health. “If your parent or another close relative had early-onset, you should probably be tested—neuropsychologically tested, but also genetically tested, as there are some definitive genetic markers.”
The good news is that early-onset Alzheimer’s disease is much rarer than late-onset. Most people worried about memory and other cognitive issues before age 65 are probably just experiencing normal aging changes. And when there is some cognitive impairment, it’s likely to be due to reasons other than early-onset Alzheimer’s disease, such as medical conditions, emotional problems like depression or stress, sleep impairment, or medication side effects.
