As a child, actor Bruce Willis struggled with a severe stutter that was so debilitating it could take him several minutes to finish a sentence. But when he was cast in a school play, he found that the stutter completely vanished as he spoke his character’s memorized lines onstage. That discovery helped lead him to study acting at Montclair State University, where he received speech therapy to fully overcome the stutter. He would go on to a four-decade career as one of Hollywood’s top A-list actors, headlining movies such as Armageddon, The Sixth Sense, and the classic Die Hard franchise.
So when Willis, now 71, began having difficulties finding words several years ago, his wife, Emma Heming Willis, initially thought it was a return of that childhood stutter. “It was very subtle at first, but our communication wasn’t really there like it had been in the past,” says Heming Willis, New York Times bestselling author of The Unexpected Journey: Finding Strength, Hope, and Yourself on the Caregiving Path. “It was really language that I noticed first. But it never seemed to bother him. And never in my wildest dreams did I think it was a young-onset dementia that was surfacing.”
Early signs of frontotemporal dementia
Family has always been at the center of Willis’s life. He has three adult daughters with his former wife, actor Demi Moore, and two younger girls with Heming Willis, whom he married in 2009. The blended family has remained close. “Bruce has always been a very present dad, very present husband,” Heming Willis says. “He’s always said his most important role is one of being a father.”
But as that easy connection started to slip, beginning with his words, Heming Willis knew that something was wrong. And in fact, it wasn’t just an old stutter resurfacing—it was the first sign of a devastating neurodegenerative disease. Willis was eventually diagnosed with frontotemporal dementia (FTD), with its verbal-led form, primary progressive aphasia (PPA). That answer took time. “The first diagnosis that we received was aphasia, and it wasn’t until a year later that they landed on FTD,” Heming Willis says. “Aphasia was a symptom of a disease, not the actual disease.” The family received the full diagnosis at the end of 2022.
What is frontotemporal dementia?
Frontotemporal dementia is a term for several conditions, says David Clark, MD, associate professor of clinical neurology at Indiana University Health in Indianapolis. “Within frontotemporal dementia there are three major syndromes: the behavioral variant, semantic dementia, and progressive nonfluent aphasia,” he explains. “The aphasia form usually manifests early with word-finding difficulty, greater hesitation when trying to speak, or grammatical changes.”
Those changes can be easy to miss and sometimes appear first in writing. “You have a text message conversation with the person, and you realize they’re leaving out a lot of the simple function words,” Dr. Clark says. These are words like a, the, and, but, he, she, or we.
Gustavo Román, MD, co-director of the Nantz National Alzheimer Center at Houston Methodist Hospital in Texas, describes the same early pattern. “The main difficulty is that they start having problems finding the right word or remembering the name of a person that they have known for a while,” he says. As speech grows harder, Dr. Román offers patients a workaround. “When they just cannot come up with a way to put three or four words together, I tell them to sing,” he says. “When they sing, they’re able to speak a little bit better.”
The process of getting a diagnosis is long and difficult for many families, just as it was for Willis. “It can take an average of three to seven years to get to a diagnosis,” Heming Willis says. “It is underdiagnosed, it is misdiagnosed, it is not [noticed] enough in the doctor’s office. It can be attributed to a midlife crisis or depression or someone being bipolar.”
Part of the problem is that the people affected are often too young to fit the typical picture of dementia, so doctors may think of other conditions first. Dr. Clark says that recognition of young-onset dementia has improved in recent years and referrals now come faster.
Because an FTD diagnosis typically happens earlier in life than other dementias, families face additional burdens that aren’t a problem when someone is diagnosed with Alzheimer’s disease at 75 years old. “The biggest thing is that we’re taking people out of their work,” Dr. Clark says. “You take an individual who’s 55 and already reaching a point where they can’t hold down a job. Many of these people have children that are still in school,” he says.
Since the disease typically begins as early as the mid-40s, it often becomes noticeable at work, when patients have trouble with executive function. Executive function is the work the brain does to manage everyday tasks like making plans, solving problems, and adapting to new situations. “They make mistakes with the computer, they cannot text on the cell phone, they start having difficulty driving,” Dr. Román says. Unlike the short-term memory loss of Alzheimer’s disease, he says, FTD is primarily characterized by changes in language and behavior.
For the Willis family, the FTD diagnosis was hard to get. “I just always remember neurologists saying, ‘FTD, oh boy, that’s the one that you don’t want,’” Heming Willis says. “So then hearing it in the doctor’s office, it was like I could hear nothing else.”
