Helping Loved Ones With Cognitive Decline Give Up the Car Keys

Aug. 9, 2023 – Four years ago, Pamela Smith, a 76-year-old retiree in Orlando, FL, became concerned about her husband’s driving.

Dick Smith had recently been diagnosed with mild cognitive impairment and was in the early stages of Alzheimer’s disease, Pamela said. 

“I noticed he was wandering in the lane, and when I mentioned this to him, he would make corrections. We had his eyes checked – we thought maybe it was impaired vision – but his eyes checked out fine.”

A couple of times, Dick almost hit a concrete median on the highway. Once, he couldn’t figure out how to get out of a small parking lot. “The scariest was when he was pulling away from a red light, he would make a right turn into ongoing traffic, not allowing anywhere near enough room for the cars that were coming fast. I would just hold my breath, waiting for a possible crash.”

Just as Pamela prepared to to talk with her husband about turning over the keys — a conversation that made her very anxious –Dick himself realized it was no longer safe for him to drive.  

“The final straw was when I was coming off our highway and merging into traffic, and I couldn’t judge the speed of that traffic, to the point that my heart actually skipped a beat or two,” said Dick Smith, 80, a retired health care administrator. 

“I was mature enough to realize that I’d rather make sure we’re all alive and safe and no one gets killed, so I knew I had to give up driving,” he said. “I’ve always loved driving, especially long distances, so it was very painful. It’s still painful.”

A Common Problem

It’s fortunate that Dick was self-aware enough to recognize that he could no longer drive safely. Unfortunately, many people are remaining behind the wheel, even with cognitive impairments, new research has found. 

The investigators studied 635 people with an average age of 77. The group included Mexican American and non-Hispanic White people. All had shown signs of cognitive impairment (loss of thinking skills), based on a test called the Montreal Cognitive Assessment.

Of the people in the study, 61.4% were current drivers and about one-third of their caregivers had concerns about the safety of their driving.

Start the Conversation Early

Monica Moreno, senior director of care and support at the Alzheimer’s Association, said it’s important to recognize that each person goes through Alzheimer’s in a different way. 

“We would never say that everyone living with any type of cognitive impairment should automatically stop driving,” she said. “It’s a very individual experience and a decision that the family must make together with the person living with the disease, and it’s unique and special to each situation.”

Senior study author Lewis Morgenstern, MD, a professor of neurology, epidemiology, emergency medicine, and neurosurgery at the University of Michigan, agreed, noting that some people with early mild cognitive impairment “are likely safe to still drive, and driving maintains their independence and role in the community.”

But families should stay alert to concerns because “it’s inevitable that, as Alzheimer’s disease progresses – and it is a progressive disease – the person will eventually no longer be able to safely drive,” Moreno said.

At that point, according to Moreno, “telling a loved one he or she can no longer drive is one of the most difficult decisions for families to make, because driving is really a component of a person’s independence,” she said. “It’s how they stay engaged socially so they can meet with others – friends, family members, and so on.”

When we think about “taking away their keys or asking them to give up their keys, we think of the impact on the individual while they’re also experiencing other losses, and that’s huge,” said Moreno, who also heads the Alzheimer’s Association’s National Early Stage Advisory Group – a group of people with early-stage Alzheimer’s who do advocacy and education about what it feels like to be going through the process of having Alzheimer’s.

Moreno encourages families to start talking about driving as soon as the person gets diagnosed. Hopefully, during those early conversations, the person will agree to accept the feedback that the driving has become unsafe when the time comes.

Morgenstern and his co-authors noted that developing an advanced driving directive when the person is still able to do so can be helpful. 

Similar to advance directives for end-of-life care, an advanced driving directive is an “agreement between a person and trusted individual to have conversations regarding driving cessation” and allow the driver to designate another person to make driving decisions for them in the future.

Approaching the Conversation

The Alzheimer’s Association website has a section devoted to dementia and driving, including videos that provide conversational scenarios to help guide people through the delicate process of broaching the subject. 

There is also a 24/7 help line operated by health care professionals that people can call. 

“You can talk to a care consultant who can help you develop a plan for starting the conversation,” Moreno advised. “And then, after you’ve had the conversation, you can debrief with the consultant on what did and didn’t go well, so you’re working with an expert who can guide you through the entire process.”

If the Person Is Reluctant to Give Up Driving

If the person with dementia doesn’t agree, or doesn’t realize they can no longer drive safely, and you or another caregiver is unable to convince them, perhaps other family members can step in to try to do so. 

Morgenstern advises caregivers to talk to the person’s primary care doctor about safety issues in cognitive impairment, including driving and home safety.

Consider an on-the-road driving test or driving school, or even occupational therapy, he said. 

The Alzheimer’s Association’s provides information about how to get a family member evaluated. It may be more effective if the person hears the difficult news from an expert outside the family.

If a person has reached a stage in the disease where it’s dangerous for them to drive but is unwilling to accept that, families may have to control access to the car keys, Moreno said. Some families disable the car by removing the battery or not having the wires connected so that if the person does find the keys and attempts to drive, the car won’t start.

“We know that later on, as the disease progresses, even seeing the family car in the driveway may trigger the person who wants to drive,” Moreno said. “I’ve talked to families who have parked the car around the corner or even sold the car if they didn’t need it anymore so that it doesn’t trigger a memory for the person with dementia.”

She stressed the importance of early conversations about driving, while the person is still able to engage in them. “That way, if the person refuses to give up the car keys when the time comes, you know that you are carrying out their wishes, and it can help reduce some of the guilt.”

Making the Transition

Moreno pointed out that in the modern world, services like Uber and Lyft can allow people to continue being independent and being taken to activities and places they love to go so they’re not isolated.

Pamela Smith was “nervous at the beginning,” because Dick criticized her driving. “It made me very tense, and it was an unhappy situation,” she said. “We had to have several conversations about that.”

Now, he keeps his head down and looks at his phone or does crossword puzzles. “I don’t want to harm our marriage by being critical,” he explained.

He advises people to “be mature and sensible” and agree to step out from behind the wheel before something bad happens. 

“I was scared we’d lose our life savings, insurance, car, or our lives or injure or kill someone else, and that didn’t make sense to me. Even in my impaired state, I think I made a good decision, and the kids were astounded that I did that all on my own.”

Putting a Hole in Our World

CHANNEL TODAY BROADCASTING CORPORATION

Published

on


May 10, 2024 – When we’re young, we take our macula for granted. At the center of our retina – the deepest layer of the eye that’s chock-full of photoreceptors and that confers color to our world – the macula is like a high-resolution camera. As light hits our eyes, the retina’s macula recasts our world in a bloom of color with astoundingly high visual sharpness.

But as you age, your vision dulls. What once stood out sharply becomes foggy, like condensation on a windowpane. After some time, a coal-black smudge or cloudy circular area begins to affect your central vision. 

This effective blind spot widens over time if left untreated. What remains is a “macular hole” in the center of your retina.

This unfortunate series of events marks the advanced stage of age-related macular degeneration, a dangerous retinal disease that affects about 20 million people in the U.S., and nearly 200 million people worldwide. 

And it’s not getting better. Estimates are that by 2040, the disease may affect nearly 300 million people worldwide. We are very limited in our ability to treat or prevent it. Read on for what to know. 

First, What Causes Age-Related Macular Degeneration? 

AMD’s causes are varied, and whether it will affect you is mostly determined by age and genetics, said Marco Alejandro Gonzalez, MD, an ophthalmologist and vitreoretinal specialist in Delray Beach, FL. 

Because of the different cocktails that we have in terms of our genetic makeup, some people’s photoreceptor cells in the macula “basically start to shut down,” he said.

AMD’s development involves over 30 genes, and if you have a first-degree relative – parent, sibling, child – who has the disease, you’re three times more likely to get it, too. 

Gonzalez explained how the expected rise to 300 million cases by 2040 is due mostly to improved diagnostic tools, along with the fact that the world is getting older and living longer. (Usually, an optometrist can detect signs of AMD during a routine eye exam.)  

Eye experts still struggle to stop AMD’s most harmful sign – the cause of those muddy, milky, or even coal-colored circles in your central vision: geographic atrophy.

Geographic atrophy can occur in either of the two forms of age-related AMD: “dry” AMD and “wet” AMD.

Nearly every case of AMD begins as the dry kind, affecting 80% to 90% of AMD patients. 

Retinal disease expert Tiarnán Keenan, MD, PhD, offered  a vivid image of geographic atrophy for those who have dry AMD. 

“As time passes, the circular patches of GA expand like a brushfire, taking more and more vision with it, often to the point of legal blindness,” he said. 

A researcher in the Division of Epidemiology and Clinical Applications at the National Eye Institute, Keenan recently led a study that tested the efficacy of the antibiotic minocycline in slowing geographic atrophy expansion in dry AMD. The study operated on the grounds that the body’s immune system could be at play in developing the disease.

When your body’s immune system is overactive, microglial cells (central nervous system immune cells) can get into the sub-retinal space and possibly eat away at the macula and its sensitive photoreceptors. 

Though minocycline had been shown to reduce inflammation and microglial activity in the eye in diabetic retinopathy, it didn’t slow the expansion of geographic atrophy or vision loss in patients with dry AMD during Keenan’s study.

When asked if microglial activity could have very little to do with the atrophy expansion, Keenan said it’s something to consider: “Maybe microglia are just there as bystanders clearing up the debris … so inhibiting them is less likely to slow down progression.”

In future drug trials, “maybe it’s possible the minocycline or another approach to target microglia would be helpful, but it would be needed in combination with some other therapy and be ineffective by itself,” he said. 

Two Sides of the Same Disease 

In dry AMD, Gonzalez compares macular degeneration to the loss of pixels on a screen. “Some of those pixels burn out … and that’s the way you lose vision classically in the dry form.”

Wet AMD is a more progressive form of the disease. It causes abrupt vision loss due to abnormal blood vessel growth. 

“If you don’t treat wet AMD quickly, it’s game over,” warned Gonzalez. “Wet macular degeneration is the quicker process of vision loss because these blood vessels wreak havoc.” These new blood vessels bleed, causing fluid to build in the macula, which ultimately leads to scarring. 

Gonzalez shed light on why wet AMD develops. “The wet form, for some reason, is the body’s last-ditch effort to try to kind of ‘help’ a dying macula. … When these blood vessels start to grow under the retina, they quickly destroy the architecture of the macula.”

Stopping the Bleeding in Wet AMD

Though wet AMD is rarer, it’s more treatable than dry AMD. Signs and symptoms can be eased with various therapies injected into the eye. 

Putting it simply, Gonzalez said these therapies to treat wet AMD “all basically do the same thing. They make these new blood vessels regress temporarily before they cause damage to the macula.”

The injected medication clears away those blood vessels and restores the architecture of the macula. People can recover some vision in this way, but it’s only a temporary tune-up, and shots must be given as often as once a month.

“Degeneration of the cells is still the main problem. You’re not stopping that. But degeneration itself is a lot slower than actual vision loss associated with these blood vessels.” 

The Struggle in Developing New Treatments 

According to Keenan, “nobody has been able to stop geographic atrophy from happening” in either form of AMD. “So, that’s the main work in the field with trials.”

In December 2023, the FDA approved two new drugs: Syfovre and Izervay, both of which only slow geographic atrophy. Degeneration still happens, regardless. 

Keenan explained how these two new drugs are “complement inhibitors … given by injection into the eye once a month or so.” 

“Complement” refers to the body’s complement pathway, a trigger that activates a cascade of proteins in enhancing immune response. 

Clinical trials showed Syfovre slowing the rate of geographic atrophy by up to 22% over 2 years, and Izervay up to 14% over 1 year. 

Though these drugs are a new weapon against this troublesome affliction, they aren’t without their complications. 

“Anytime you give an injection in the eye, there’s always the risk of an infection because you’re introducing something from the outside. So that’s the biggest risk,” explained Gonzalez. 

An infection is uncommon, but potentially devastating, as you can lose your eye altogether. There’s also the chance of a damaging reaction to the shot.

“You have to pick and choose your patients,” said Gonzalez. “Not everybody is a good candidate for those new shots … and the patient is never going to see better. … It’s a harder sell than the ones for wet AMD.”

A Common Protective Measure 

Keenan and Gonzalez both have a fair degree of confidence in reducing the risk of AMD with vitamin therapy. 

As a bit of background on how vitamins were found to act as a sort of preventive measure, Gonzalez said, “In the early and late ‘90s, there were series of studies which were called the age-related eye disease studies.” These are now referred to as AREDS 1 and AREDS 2.

Researchers proved that a certain cocktail of vitamins slowed down degeneration. The most is a combo of antioxidants: vitamins C and E and lutein and zeaxanthin, all of which are in the AREDS 2 formula.

People who took these vitamins had a lower chance of losing their vision over the next 2 to 5 years. “[The combo] seems to be complementary and additive … with a combined treatment effect of 55% to 60%, an excellent safety record, and very low cost,” Keenan said. 

Gonzalez recommends the AREDS 2 formula of vitamins to every patient of his. “It’s such an easy thing to take, and the downside is minimal.”

Unfortunately, if your genes make you more likely to have the condition, a change in diet or vitamin use could have no effect. 

Dire? Possibly. But not all is lost in this fight. 

Vigilance with AMD and What to Do Next if You’re Diagnosed

Gonzalez is adamant in educating his patients before time has run out on treating AMD. Recognition is key. “The most common reason a lot of these people get to me ‘too late’ is they don’t realize there’s a problem.”

He explained a typical scenario: “Let’s say you have macular degeneration in both eyes at different stages. One of your eyes starts developing wet macular degeneration … so the better eye takes over and you may not notice there’s a problem.” 

Even after a patient is diagnosed with AMD, they usually see a specialist only twice a year. Gonzalez often tells his patients to cover one of their eyes to make sure their vision is intact in both eyes. “You’ll be able to pick up on subtle differences” in each eye, he said. 

This type of self-care and vigilance can be the difference between successfully living with and treating the disease for the rest of your life, and trying to get help when it’s simply too late. 

For wet AMD, as mentioned before, a round of injections is basically what everyone does. Without quick, invasive treatment, the point of no return approaches rapidly.

Federal Experts Talk Bird Flu ‘What Ifs’ in WebMD Live Event

CHANNEL TODAY BROADCASTING CORPORATION

Published

on


May 16, 2024 – Multiple U.S. agencies are working to contain the recent bird flu outbreak among cattle to prevent further spread to humans (beyond one case reported in early April) and use what we learned before, during, and after the COVID-19 pandemic to keep farm workers and the general public safe. 

Fingers crossed, the bird flu will be contained and peter out. Or the outbreak could continue to spread among dairy cattle and other animals, threatening the health and livelihoods of farmers and others who work with livestock.

Or the virus could change in a way that makes it easier to infect and spread among people. If this happens, the worst-case scenario could be a new influenza pandemic. 

With so many unknowns, WebMD brought together experts from four federal agencies to talk prevention, monitoring, and what the “what ifs” of bird flu might look like.

Communication with the public “about what we know, what we don’t know, and ways you and your family can stay safe is a priority for us at CDC,” said Nirav D. Shah, MD, JD, the CDC’s principal deputy director. “We at the federal level are responding, and we want the public to be following along.”

People should consult the websites for the CDC, FDA, U.S. Department of Agriculture (USDA), and the Administration for Strategic Preparedness and Response (ASPR) for updates.  

It is essential to not only stay informed, but to seek trusted sources of information, Shah said during “Bird Flu 2024 – What You Need to Know,” an online briefing jointly sponsored by the CDC and WebMD. 

An ‘Experimental Hamburger’

If one take-home message emerged from the event, it was that the threat to the general public remains low. 

The retail milk supply is safe, although consuming raw or unpasteurized milk is not recommended. “While commercial milk supply is safe, we strongly advise against drinking raw milk,” said Donald A. Prater, DVM, acting director for the FDA’s Center for Food Safety and Applied Nutrition.

As for other foods, thoroughly cooked eggs are less risky than raw eggs, and the nation’s beef supply remains free of the virus as well.

For years, federal inspectors have purchased and tested meat at retail stores, said Eric Deeble, DVM, USDA deputy assistant secretary for the Office of Congressional Relations. So far, H5N1, the virus behind bird flu, has not been detected in beef. 

The USDA took testing a step further and recently cooked ground beef from dairy cows in their lab. Using what Deeble described as an “experimental hamburger,” the agency showed cooking beef to 165 F or higher kills the virus if it ever becomes necessary.

The federal government now requires all cattle be tested and be free of bird flu virus before crossing any state lines. The government is also reimbursing farmers for veterinary care and loss of business related to the outbreak, and supply personal protective equipment (PPE) like gloves, masks, and face shields to workers. 

Vaccination Not Recommended Now

Federal scientists know enough about H5N1 virus to create vaccines against it quickly if the need arises. It’s more about planning ahead at this point. “Vaccines are not part of our response right now,” said David Boucher, PhD, director of infectious diseases preparedness and response at the Administration for Strategic Preparedness and Response. 

If the virus changes and becomes a bigger threat to people, “we have the building blocks to produce a vaccine,” Boucher added. 

An event attendee asked if the seasonal flu shot offers any protection. “Unfortunately, the flu shot you got last year does not provide great protection from the avian flu,” Shah responded. “It might do a little bit … but that is the vaccine for seasonal flu. This is something more novel.”

Treatments Stockpiled and Ready

Antiviral medications, which if given early in the course of bird flu infection could shorten the severity or duration of illness, are available now, Shah said. The dairy farmer who was infected with bird flu earlier this year responded to oseltamivir (Tamiflu) treatment, for example. 

When it comes to bird flu symptoms, the fact that the only infected person reported so far this year developed pink eye, also known as conjunctivitis, is interesting, Shah said. Officials would have expected to see more typical seasonal flu symptoms, he added. 

“Influenza is not a new virus,” Boucher said. “With this strain of influenza, we are not seeing any genetic markers associated with resistance to antivirals. That means the antivirals we take for seasonal influenza would also be available if needed to treat H5N1.”

ASPR has stockpiled Tamiflu and three other antivirals. “We do have tens of millions of courses that can be distributed around the country if we need them,” he added.

“Influenza is an enemy we know well,” Boucher said. That is why “we have antivirals ready to go now and many types of PPE.”

Science in Action

The feds intend to stay on the case. They will continue to monitor emergency department visits, lab test orders, and wastewater samples for any changes suggesting a human pandemic risk is growing.

“While we’ve learned a great deal, there are still many things we do not know,” Deeble said. 

Shah added, “As in any outbreak, this is an evolving situation and things can change. What you are seeing now is science in action.”
