When we think of dementia, memory loss is usually the first symptom that comes to mind.
But neurologists say there’s another early warning sign that often flies under the radar.
It doesn’t involve forgetfulness—but rather, a quiet shift in how someone behaves or engages with the world around them.
Families often overlook it or assume it’s just part of getting older.
Spotting it early, however, could make a meaningful difference in care and quality of life.
Apathy: the subtle change that’s easy to miss
Apathy is defined as a loss of interest or motivation in everyday activities.
It’s not the same as feeling sad or burned out—it’s more like a quiet withdrawal.
Neurologists say apathy is one of the earliest symptoms of frontotemporal dementia (FTD), and it’s also seen in other forms such as Alzheimer’s and Lewy body dementia.
Dr. Adel Aziz, a neurologist at JFK University Medical Center, explains it this way: "A person who once planned outings or made social calls may simply stop engaging. Loved ones might interpret this as needing alone time, but it could be something more serious."
Dr. Katherine D. Amodeo, a neurologist at New York Medical College, adds: "It can appear that the person doesn’t care or is depressed, when in fact, it’s something different entirely."

Why apathy appears in dementia
The reason apathy often shows up early in dementia has to do with changes in the brain, especially in areas responsible for motivation and goal-setting.
In frontotemporal dementia, for instance, the frontal lobe—which controls mood, personality, and decision-making—is disproportionately affected.
Dr. Daniel Lesley, a neurologist with Remo Health, notes that apathy may also come from how a person feels about their situation.
"Individuals may feel everything is more difficult or not worth the effort," he explains.
"They might also feel like they’re a burden."
A sign that may signal faster decline
Apathy isn’t just a symptom—it can also speed up cognitive decline.
Dr. Lesley explains that people who lose motivation are less likely to stay socially engaged, exercise, or pursue mentally stimulating activities.
Over time, that lack of engagement can make symptoms worse and limit a person’s ability to adapt to new challenges.

How to recognize apathy

Here are some common signs to watch for:
It’s also important to consider whether other signs of dementia are present. According to Dr. Amodeo, red flags that may accompany apathy include:
Of course, apathy can also occur with conditions like depression, so it’s important not to jump to conclusions.
A proper evaluation by a doctor is the best first step.

What to do if you’re concerned
If you or someone you care about is showing signs of apathy—especially alongside other cognitive changes—it’s time to speak with a primary care doctor.
They can assess the situation and, if needed, refer you to a neurologist or memory care specialist for further testing.
Early diagnosis opens the door to medications, support services, and lifestyle changes that may help slow the disease’s progression.
Dr. Tara Carlisle, a behavioral neurologist at UCHealth, emphasizes that there are options available.
"While there’s no cure for dementia, we have treatments that can ease symptoms," she says. "Lifestyle changes can also have a real impact."
Simple habits that support brain health
Experts recommend the following lifestyle habits to help support cognitive health at any age:
These changes won’t prevent dementia altogether, but they may help protect your brain and improve your overall well-being.

Don’t go through it alone
Apathy, whether linked to dementia or another condition, can be challenging for families.
Dr. Amodeo recommends seeking emotional support through therapy, counseling, or caregiver groups.
"Reach out to your primary care provider, who may refer you to a psychiatrist or psychologist," she says.
"There are also directories like Psychology Today that can help you find someone local."
Noticing subtle changes like apathy can be the first step in getting the right support.
If something feels off, trust your instincts and talk to a doctor.

How to recognize apathy
Because apathy isn’t a condition itself, it can be difficult to spot.
Here are some common signs to watch for:
- Loss of interest in activities that used to bring joy
- Lack of motivation to complete daily tasks, including essentials like eating or paying bills
- Avoiding social interaction
- Neglecting personal care or home hygiene
It’s also important to consider whether other signs of dementia are present. According to Dr. Amodeo, red flags that may accompany apathy include:
- Gradual memory loss or trouble with focus and attention
- Language difficulties or confusion
- Mood or personality changes
- Delusions or hallucinations
- Sleep disruptions, including acting out dreams or experiencing "sundowning" (increased confusion later in the day)
Of course, apathy can also occur with conditions like depression, so it’s important not to jump to conclusions.
A proper evaluation by a doctor is the best first step.

- Exercise regularly, ideally several times per week
- Follow a Mediterranean-style diet with fruits, vegetables, healthy fats, whole grains, and lean protein
- Stay mentally and socially active through reading, puzzles, classes, or hobbies
- Reduce stress using tools like meditation, deep breathing, or prayer
- Get consistent, quality sleep
- Address hearing or vision problems early on
These changes won’t prevent dementia altogether, but they may help protect your brain and improve your overall well-being.
