Experts seek to raise awareness of Frontotemporal Dementia

FIRST OF TWO PARTS | LAST OF TWO PARTS


A PERSON diagnosed with Frontotemporal Dementia became obsessed with winning a car, so he spent nearly $700,000 with Publisher’s Clearing House before his family realized what had happened.

Another, who had become preoccupied with car suspensions, rocked every vehicle he saw until the alarms sounded, never understanding that others might find this disruptive. Yet another felt perfectly justified in turning to prostitution to finance her affinity for butterscotch candies and cigarettes.

Uninhibited spending and loss of judgment are typical components of the degenerative brain disease that attacks slowly and yields devastating results, often stripping patients of language skills and inciting behavior so bizarre, destructive and unpredictable that they’re frequently misdiagnosed with psychiatric disorders.

Frontotemporal Dementia, or FTD, is not everyday terminology — yet. But it’s on the periphery of public awareness the way Alzheimer’s disease was 20 years ago.

Among those afflicted with some version of the disorder is Dr. Ed Cadman, who stepped down from his position as dean of the John A. Burns School of Medicine at the University of Hawaii early in 2005. The former chief of staff at Yale-New Haven Hospital disclosed that he had been suffering from Primary Progressive Aphasia, a generally recognized subtype of FTD that begins with language problems. He said publicly that his symptoms began in early 2003.

Experts regard FTD as the second most prevalent cause of dementia in patients under 65. Alzheimer’s, which affects 4.5 million people in the United States, causes 60 percent of dementias. But FTD strikes otherwise healthy individuals in their 40s, 50s and early 60s, often at the peak of their earning power and while they are raising children. In addition, symptoms may vary enough that casual acquaintances and workmates underestimate the severity of the illness. But that’s not true for those who live with the patient.

“With FTD, we see families in major crisis,” said Geri Hall, a clinical professor at the University of Iowa College of Nursing and an advance-practice nurse who has worked with hundreds of FTD patients since 1978. “The problem is that the patient has not been determined to be incompetent, and nobody wants to take away the autonomy of someone who is not impaired. So the caregiver is constantly being barraged by negative restrictive feedback that he is trying to limit this competent person. It’s like swimming in one of those endless pools.”

THE QUEST to understand the cause of the illness and raise awareness about the variety of its manifestations drove the curriculum of the fifth annual International Conference on Frontotemporal Dementias in San Francisco earlier this month. Approximately 400 physicians, research scientists and caregivers attended the three-day meeting led by neurologist Bruce Miller, director of the Memory and Aging Center at the University of California, San Francisco.

One barrier to public knowledge about FTD is that it can’t be reduced to “10 early warning signs,” like Alzheimer’s. Though many similarities exist, the key difference is that FTD patients display no real memory loss. Results of intelligence tests remain normal for a long time, and patients with unimpaired motor control “can be very athletic late into the disease,” said Hall.

Over time the illness attacks the frontal lobe and anterior temporal lobes, eliciting a wide array of symptoms relating to mood and irritability, decision-making, speaking and writing proficiency, ability to manage finances, impulse control and empathy for others. Delusions and paranoia also may be present. And patients can become apathetic or highly aggressive — verbally, physically or sexually.

Their lack of judgment makes them unable to recognize consequences of behavior or appreciate threats to their safety — or the safety of others. Complicating matters even further, “people with FTD remain clever and very often develop sort of ingenious ways of getting around obstacles,” said Hall, who has worked extensively at the Mayo Clinic in Scottsdale, Ariz.

If a patient has become an unsafe driver and a relative disables the car, the patient will find a way to get it working. If the car is removed, he’ll try to buy another. If debt at home or at the office begins to run high, he’ll have an almost logical excuse. It’s not uncommon for the patient to accuse a loved one of wrongdoing or limit communication between doctors and family members in ongoing attempts to retain autonomy.

Yet on the surface, the FTD patient will appear to agree with everything a doctor tells him. “‘Yes, someone in my condition shouldn’t drive,'” mimics Hall. “But in five minutes, they’re back in the car. The family doesn’t have any say with these patients.” And proving the patient’s incompetence is nearly impossible if he can answer a few questions in a somewhat logical manner and act normally for a sustained period — not difficult when behavioral anomalies appear only once a day or a few times a week.

OF GREATEST concern is that FTD patients become more dangerous to themselves and others as time progresses. The real-life examples gleaned from nurses, doctors and interviews with caregivers differ in the details, but all contain common threads.

When police stopped a 63-year-old former CEO driving 75 mph and crossing the center line to get to a JC Penney’s sale, she felt her actions were perfectly appropriate. Still, she promised not to drive again, only to be arrested two weeks later when she caused an accident by using her car to push another when she got tired of waiting behind a funeral procession. She tried to pay cash to the other driver at the scene so family members wouldn’t discover what had happened.

Others, falling prey to the oral fixation common in the illness, ate things such as tea bags, candles and glass Christmas balls, or even their own bowel movements. And some, not knowing when to stop eating, consumed food to the point of bursting, exhibited in the form of violent projectile vomiting.

“Their prefrontal cortex is damaged,” Hall said. “So they make consistently poor judgments, and lose their sense of risk. The reasoning is gone.”

This is why the professional environment is loaded with moral and ethical complexities. “If I have a patient who’s working, I want that patient out of that work place and on disability as quickly as possible,” Hall said. Patients may behave inappropriately or simply be unable able to perform due to cognitive decline, leaving co-workers to pick up the slack. Then, because nobody understands the nature of the illness, “and the patient looks and sounds good,” he may find himself fired without compensation.

FTD throws families into chaos. Education about and acknowledgment of the illness’s magnitude is essential for loved ones coping with devastating changes, experts say. And it’s the only way that patients will receive the care they need.

 

PART II:

Diagnosis of disorder remains problematic

Patients do not show all symptoms, thus complicating analysis

FIRST OF TWO PARTS | LAST OF TWO PARTS

 



FRONTOTEMPORAL DEMENTIA is a complex disease that’s just beginning to enter public consciousness the way Alzheimer’s disease did about 20 years ago. Because it can begin with a language disorder, motor-control problems, inappropriate behavior or a series of bad decisions, it can be misdiagnosed as a psychiatric disorder, attributed to stress or simply ignored for a long time.

Families, close friends or co-workers may notice bizarre, even dangerous behavior in someone close to them, but ascertaining the cause or even the fact that the person is ill can take months — and sometimes years.

Early symptoms may include speaking or comprehension difficulties to the point where interaction with others becomes limited, irritability, impairments in financial decision-making, inability to organize or solve problems, lack of sympathy, decline in cognition or lack of attention to appearance. Complicating the analysis is the fact that no single patient exhibits all of the symptoms.

To date, the only way to obtain a definitive diagnosis is during autopsy.

Consequently, detecting FTD remains more art than science. Magnetic Resonance Imaging and CT scans can help rule out a brain tumor and show cerebral atrophy in the frontal and temporal lobes, but these and PET scans “are not a means for making a diagnosis,” said Tiffany Chow, an associate professor of neurology and geriatric psychiatry at the University of Toronto.

In other words, the brain can still look fairly good when patient behavior indicates otherwise. Neuropsychological tests can help, but Chow said that nothing is more effective than a complete examination and history of speech impairments and/or behavioral changes.

But this can also be problematic. Most clinicians agree that information from a patient is unreliable, said Geri Hall, a clinical professor at the University of Iowa College of Nursing, and an advance-practice nurse who has worked with hundreds of FTD patients since 1978. They may admit to limitations related to language, but as the disease progresses, lack of insight prohibits them from recognizing, or caring about, their own deficiencies.

Compounding the problem is the fact that primary-care physicians and neurologists in private practice may have limited knowledge of the disease and difficulty obtaining information. Family members can be reluctant to tell the truth, out of embarrassment or fear of repercussions from a now-volatile loved one. Those who haven’t lived with the patient on a daily basis have little to report.

INFORMATION about the cause of FTD is limited, though the latest research indicates that a progranulin gene mutation on the 17th chromosome plays a role. Another important factor, the tau protein, also is prominent in Alzheimer’s disease. Essentially, misfolding proteins become like tangled train tracks that cause horrific wrecks in the brain. About 40 percent of cases are believed to have a genetic component. The rest are random.

Because there is no treatment or cure, clinicians address only the symptoms, often with medication to control behavior. Patients die from complications of the illness within three to 15 years.

To raise awareness, the University of California, San Francisco, Memory & Aging Center is working on a program they hope will air on public television in the next couple of years. In the trailer, a woman talked about her 49-year-old husband who took their young daughter into a rapidly flowing river, keeping her secure as she held the end of a stick under his control. Then he let go. For the safety of her children, she made the painful decision to put him in a nursing home.

Typically, this leads to a new set of problems. Because patients are often young and physically able, they are too strong for staff members prepared only for the frail elderly — especially if the FTD patient becomes moody and aggressive. When asked if her patients are expelled from nursing homes, Jill Shapira, a nurse practitioner who has worked with hundreds of FTD patients at UCLA, said simply, “Big time.”

If there is any good news, it’s the research that neurologist Bruce Miller, director of UCSF’s Memory & Aging Center, has conducted on the artistic talents elicited in some patients during the course of this illness. At the International Conference on Frontotemporal Dementias in San Francisco earlier this month, Miller led a tour of patient work in the Yerba Buena Center for the Arts, where paintings by Hawaii artist Peggy Chun were featured. Chun has ALS (Amyotrophic Lateral Sclerosis, or Lou Gehrig’s disease), an illness with “strong ties” to FTD, according to Miller.

“The dark ages is where we’ve been until recently,” Miller said. “My hope is that within the next year, we’ll see the beginnings of effective treatment for FTD.”

In the meantime, families struggle to understand an illness with multiple components and an assortment of severe and subtle symptoms that essentially do one thing: destroy the essence of the person they love. “He’s here, but he’s not,” a woman in the UCSF video explained. “It’s a continual, day-to-day grieving process.”

 

TYPES OF FTD

Frontotemporal Dementia (also called Frontotemporal Lobar Degeneration) is an umbrella term that covers several disease subtypes. They are named according to the way the disease began. All doctors agree that as each one progresses, though the severity of symptoms may vary, they all begin to resemble one another.

» Primary Progressive Aphasia or Progressive Non-Fluent Aphasia: Begins with language disorder and may remain isolated there for up to two years. All patients suffer behavioral symptoms and cognitive decline as the disease spreads.

» Semantic dementia: Language problems initially, primarily with comprehension.

» Pick’s Disease: Immortalized in a tragic plot turn in Sue Monk Kidd’s “The Mermaid’s Chair” and first described by Arnold Pick in 1892. Behavioral symptoms exhibited first.

» Corticobasal Degeneration: Begins with motor control and coordination problems.

» Progressive Supranuclear Palsy: A related disorder that begins with problems with gait and balance.
