For older adults, smelling the roses may be more difficult
Young and old alike are affected – more than 80%-90% of those diagnosed with the virus, according to some estimates. While most people recover in a few months, 16% take half a year or longer to do so, research has found. According to new estimates, up to 1.6 million Americans have chronic olfactory dysfunction due to COVID-19.
Seniors are especially vulnerable, experts suggest. “We know that many older adults have a compromised sense of smell to begin with. Add to that the insult of COVID, and it made these problems worse,” said Dr. Jayant Pinto, professor of surgery and a specialist in sinus and nasal diseases at the University of Chicago Medical Center.
Recent data highlight the interaction between COVID-19, advanced age, and loss of smell. When Italian researchers evaluated 101 patients who’d been hospitalized for mild to moderate COVID-19, 50 showed objective signs of smell impairment 6 months later. Those 65 or older were nearly twice as likely to be impaired; those 75 or older were more than 2½ times as likely.
Most people aren’t aware of the extent to which smell can be diminished in later life. More than half of 65- to 80-year-olds have some degree of smell loss, or olfactory dysfunction, as it’s known in the scientific literature. That rises to as high as 80% for those even older. People affected often report concerns about safety, less enjoyment eating, and an impaired quality of life.
But because the ability to detect, identify, and discriminate among odors declines gradually, most older adults – up to 75% of those with some degree of olfactory dysfunction – don’t realize they’re affected.
A host of factors are believed to contribute to age-related smell loss, including a reduction in the number of olfactory sensory neurons in the nose, which are essential for detecting odors; changes in stem cells that replenish these neurons every few months; atrophy of the processing center for smell in the brain, called the olfactory bulb; and the shrinkage of brain centers closely connected with the olfactory bulb, such as the hippocampus, a region central to learning and memory.
Also, environmental toxic substances such as air pollution play a part, research shows. “Olfactory neurons in your nose are basically little pieces of your brain hanging out in the outside world,” and exposure to them over time damages those neurons and the tissues that support them, explained Pamela Dalton, PhD, a principal investigator at the Monell Chemical Senses Center, a smell and taste research institute in Philadelphia.
Still, the complex workings of the olfactory system have not been mapped in detail yet, and much remains unknown, said Dr. Sandeep Robert Datta, professor of neurobiology at Harvard Medical School, Boston.
“We tend to think of our sense of smell as primarily aesthetic,” he said. “What’s very clear is that it’s far more important. The olfactory system plays a key role in maintaining our emotional well-being and connecting us with the world.”
Dr. Datta experienced this after having a bone marrow transplant followed by chemotherapy years ago. Unable to smell or taste food, he said, he felt “very disoriented” in his environment.
Common consequences of smell loss include a loss of appetite (without smell, taste is deeply compromised), difficulty monitoring personal hygiene, depression, and an inability to detect noxious fumes. In older adults, this can lead to weight loss, malnutrition, frailty, inadequate personal care, and accidents caused by gas leaks or fires.
Jerome Pisano, 75, of Bloomington, Ill., has been living with smell loss for 5 years. Repeated tests and consultations with physicians haven’t pinpointed a reason for this ailment, and sometimes he feels “hopeless,” he admitted.
Before he became smell-impaired, Mr. Pisano was certified as a wine specialist. He has an 800-bottle wine cellar. “I can’t appreciate that as much as I’d like. I miss the smell of cut grass. Flowers. My wife’s cooking,” he said. “It certainly does decrease my quality of life.”
Smell loss is also associated in various research studies with a higher risk of death for older adults. One study, authored by Dr. Pinto and colleagues, found that older adults with olfactory dysfunction were nearly three times as likely to die over a period of 5 years as were seniors whose sense of smell remained intact.
“Our sense of smell signals how our nervous system is doing and how well our brain is doing overall,” Dr. Pinto said. According to a review published earlier this year, 90% of people with early-stage Parkinson’s disease and more than 80% of people with Alzheimer’s disease have olfactory dysfunction – a symptom that can precede other symptoms by many years.
There is no treatment for smell loss associated with neurological illness or head trauma, but if someone has persistent sinus problems or allergies that cause congestion, an over-the-counter antihistamine or nasal steroid spray can help. Usually, smell returns in a few weeks.
For smell loss following a viral infection, the picture is less clear. It’s not known, yet, which viruses are associated with olfactory dysfunction, why they damage smell, and what trajectory recovery takes. COVID-19 may help shine a light on this since it has inspired a wave of research on olfaction loss around the world.
“What characteristics make people more vulnerable to a persistent loss of smell after a virus? We don’t know that, but I think we will because that research is underway and we’ve never had a cohort [of people with smell loss] this large to study,” said Dr. Dalton, of the Monell center.
Some experts recommend smell training, noting evidence of efficacy and no indication of harm. This involves sniffing four distinct scents (often eucalyptus, lemon, rose, and cloves) twice a day for 30 seconds each, usually for 4 weeks. Sometimes the practice is combined with pictures of the items being smelled, a form of visual reinforcement.
The theory is that “practice, practice, practice” will stimulate the olfactory system, said Charles Greer, PhD, professor of neurosurgery and neuroscience at Yale University, New Haven, Conn. Although scientific support isn’t well established, he said, he often recommends that people who think their smell is declining “get a shelf full of spices and smell them on a regular basis.”
Richard Doty, PhD, director of the University of Pennsylvania’s Smell and Taste Center, remains skeptical. He’s writing a review of smell training and notes that 20%-30% of people with viral infections and smell loss recover in a relatively short time, whether or not they pursue this therapy.
“The main thing we recommend is avoid polluted environments and get your full complement of vitamins,” since several vitamins play an important role in maintaining the olfactory system, he said.

Seniors with COVID-19 show unusual symptoms, doctors say
complicating efforts to ensure they get timely and appropriate treatment, according to physicians.
COVID-19 is typically signaled by three symptoms: a fever, an insistent cough, and shortness of breath. But older adults – the age group most at risk of severe complications or death from this condition – may have none of these characteristics.
Instead, seniors may seem “off” – not acting like themselves – early on after being infected by the coronavirus. They may sleep more than usual or stop eating. They may seem unusually apathetic or confused, losing orientation to their surroundings. They may become dizzy and fall. Sometimes, seniors stop speaking or simply collapse.
“With a lot of conditions, older adults don’t present in a typical way, and we’re seeing that with COVID-19 as well,” said Camille Vaughan, MD, section chief of geriatrics and gerontology at Emory University, Atlanta.
The reason has to do with how older bodies respond to illness and infection.
At advanced ages, “someone’s immune response may be blunted and their ability to regulate temperature may be altered,” said Dr. Joseph Ouslander, a professor of geriatric medicine at Florida Atlantic University in Boca Raton.
“Underlying chronic illnesses can mask or interfere with signs of infection,” he said. “Some older people, whether from age-related changes or previous neurologic issues such as a stroke, may have altered cough reflexes. Others with cognitive impairment may not be able to communicate their symptoms.”
Recognizing danger signs is important: If early signs of COVID-19 are missed, seniors may deteriorate before getting needed care. And people may go in and out of their homes without adequate protective measures, risking the spread of infection.
Quratulain Syed, MD, an Atlanta geriatrician, describes a man in his 80s whom she treated in mid-March. Over a period of days, this patient, who had heart disease, diabetes and moderate cognitive impairment, stopped walking and became incontinent and profoundly lethargic. But he didn’t have a fever or a cough. His only respiratory symptom: sneezing off and on.
The man’s elderly spouse called 911 twice. Both times, paramedics checked his vital signs and declared he was OK. After another worried call from the overwhelmed spouse, Dr. Syed insisted the patient be taken to the hospital, where he tested positive for COVID-19.
“I was quite concerned about the paramedics and health aides who’d been in the house and who hadn’t used PPE [personal protective equipment],” Dr. Syed said.
Dr. Sam Torbati, medical director of the emergency department at Cedars-Sinai Medical Center, Los Angeles, describes treating seniors who initially appear to be trauma patients but are found to have COVID-19.
“They get weak and dehydrated,” he said, “and when they stand to walk, they collapse and injure themselves badly.”
Dr. Torbati has seen older adults who are profoundly disoriented and unable to speak and who appear at first to have suffered strokes.
“When we test them, we discover that what’s producing these changes is a central nervous system effect of coronavirus,” he said.
Laura Perry, MD, of the University of California, San Francisco, saw a patient like this several weeks ago. The woman, in her 80s, had what seemed to be a cold before becoming very confused. In the hospital, she couldn’t identify where she was or stay awake during an examination. Dr. Perry diagnosed hypoactive delirium, an altered mental state in which people become inactive and drowsy. The patient tested positive for coronavirus and is still in the ICU.
Anthony Perry, MD, of the department of geriatric medicine at Rush University Medical Center in Chicago, tells of an 81-year-old woman with nausea, vomiting, and diarrhea who tested positive for COVID-19 in the emergency room. After receiving intravenous fluids, oxygen, and medication for her intestinal upset, she returned home after 2 days and is doing well.
Another 80-year-old Rush patient with similar symptoms – nausea and vomiting, but no cough, fever, or shortness of breath – is in intensive care after getting a positive COVID-19 test and due to be put on a ventilator. The difference? This patient is frail with “a lot of cardiovascular disease,” Dr. Perry said. Other than that, it’s not yet clear why some older patients do well while others do not.
So far, reports of cases like these have been anecdotal. But a few physicians are trying to gather more systematic information.
In Switzerland, Sylvain Nguyen, MD, a geriatrician at the University of Lausanne Hospital Center, put together a list of typical and atypical symptoms in older COVID-19 patients for a paper to be published in the Revue Médicale Suisse. Included on the atypical list are changes in a patient’s usual status, delirium, falls, fatigue, lethargy, low blood pressure, painful swallowing, fainting, diarrhea, nausea, vomiting, abdominal pain, and the loss of smell and taste.
Data come from hospitals and nursing homes in Switzerland, Italy, and France, Dr. Nguyen said in an email.
On the front lines, physicians need to make sure they carefully assess an older patient’s symptoms.
“While we have to have a high suspicion of COVID-19 because it’s so dangerous in the older population, there are many other things to consider,” said Kathleen Unroe, MD, a geriatrician at Indiana University, Indianapolis.
Seniors may also do poorly because their routines have changed. In nursing homes and most assisted living centers, activities have stopped and “residents are going to get weaker and more deconditioned because they’re not walking to and from the dining hall,” she said.
At home, isolated seniors may not be getting as much help with medication management or other essential needs from family members who are keeping their distance, other experts suggested. Or they may have become apathetic or depressed.
“I’d want to know ‘What’s the potential this person has had an exposure [to the coronavirus], especially in the last 2 weeks?’ ” said Dr. Vaughan of Emory. “Do they have home health personnel coming in? Have they gotten together with other family members? Are chronic conditions being controlled? Is there another diagnosis that seems more likely?”
“Someone may be just having a bad day. But if they’re not themselves for a couple of days, absolutely reach out to a primary care doctor or a local health system hotline to see if they meet the threshold for [coronavirus] testing,” Dr. Vaughan advised. “Be persistent. If you get a ‘no’ the first time and things aren’t improving, call back and ask again.”

The man’s elderly spouse called 911 twice. Both times, paramedics checked his vital signs and declared he was OK. After another worried call from the overwhelmed spouse, Dr. Syed insisted the patient be taken to the hospital, where he tested positive for COVID-19.
“I was quite concerned about the paramedics and health aides who’d been in the house and who hadn’t used PPE [personal protective equipment],” Dr. Syed said.
Dr. Sam Torbati, medical director of the emergency department at Cedars-Sinai Medical Center, Los Angeles, describes treating seniors who initially appear to be trauma patients but are found to have COVID-19.
“They get weak and dehydrated,” he said, “and when they stand to walk, they collapse and injure themselves badly.”
Dr. Torbati has seen older adults who are profoundly disoriented and unable to speak and who appear at first to have suffered strokes.
“When we test them, we discover that what’s producing these changes is a central nervous system effect of coronavirus,” he said.
Laura Perry, MD, of the University of California, San Francisco, saw a patient like this several weeks ago. The woman, in her 80s, had what seemed to be a cold before becoming very confused. In the hospital, she couldn’t identify where she was or stay awake during an examination. Dr. Perry diagnosed hypoactive delirium, an altered mental state in which people become inactive and drowsy. The patient tested positive for coronavirus and is still in the ICU.
Anthony Perry, MD, of the department of geriatric medicine at Rush University Medical Center in Chicago, tells of an 81-year-old woman with nausea, vomiting, and diarrhea who tested positive for COVID-19 in the emergency room. After receiving intravenous fluids, oxygen, and medication for her intestinal upset, she returned home after 2 days and is doing well.
Another 80-year-old Rush patient with similar symptoms – nausea and vomiting, but no cough, fever, or shortness of breath – is in intensive care after getting a positive COVID-19 test and due to be put on a ventilator. The difference? This patient is frail with “a lot of cardiovascular disease,” Dr. Perry said. Other than that, it’s not yet clear why some older patients do well while others do not.
So far, reports of cases like these have been anecdotal. But a few physicians are trying to gather more systematic information.
In Switzerland, Sylvain Nguyen, MD, a geriatrician at the University of Lausanne Hospital Center, put together a list of typical and atypical symptoms in older COVID-19 patients for a paper to be published in the Revue Médicale Suisse. Included on the atypical list are changes in a patient’s usual status, delirium, falls, fatigue, lethargy, low blood pressure, painful swallowing, fainting, diarrhea, nausea, vomiting, abdominal pain, and the loss of smell and taste.
Data come from hospitals and nursing homes in Switzerland, Italy, and France, Dr. Nguyen said in an email.
On the front lines, physicians need to make sure they carefully assess an older patient’s symptoms.
“While we have to have a high suspicion of COVID-19 because it’s so dangerous in the older population, there are many other things to consider,” said Kathleen Unroe, MD, a geriatrician at Indiana University, Indianapolis.
Seniors may also do poorly because their routines have changed. In nursing homes and most assisted living centers, activities have stopped and “residents are going to get weaker and more deconditioned because they’re not walking to and from the dining hall,” she said.
At home, isolated seniors may not be getting as much help with medication management or other essential needs from family members who are keeping their distance, other experts suggested. Or they may have become apathetic or depressed.
“I’d want to know ‘What’s the potential this person has had an exposure [to the coronavirus], especially in the last 2 weeks?’ ” said Dr. Vaughan of Emory. “Do they have home health personnel coming in? Have they gotten together with other family members? Are chronic conditions being controlled? Is there another diagnosis that seems more likely?”
“Someone may be just having a bad day. But if they’re not themselves for a couple of days, absolutely reach out to a primary care doctor or a local health system hotline to see if they meet the threshold for [coronavirus] testing,” Dr. Vaughan advised. “Be persistent. If you get a ‘no’ the first time and things aren’t improving, call back and ask again.”
