Doctors Are Most Likely to Misdiagnose These 3 Conditions Doctors working in hospitals and ERs have seen all kinds of infections and complications. But some viruses scare them more than others.

(Reuters Health) - For older adults, hearing aids may delay some forms of mental and physical decline associated with hearing loss and aging, a U.S. study suggests.

Among people who'd been diagnosed with hearing loss, those who used hearing aids were up to 18% less likely to be diagnosed with dementia, depression or fall-related injuries over the next three years, compared to people not using the devices, researchers report in the Journal of the American Geriatrics Society.

More than 27 million older Americans live with hearing loss. But only 12.3% of those with a formal diagnosis get hearing aids, the authors note.

Majority Of People Admit To Washing In Pools And Skipping A Shower, Doctors Actually Say It’s OK

Majority Of People Admit To Washing In Pools And Skipping A Shower, Doctors Actually Say It’s OK According to the CDC, 51 percent of Americans surveyed admitted to using swimming as an alternative to bathing. At least one Paramus mother says this is a non-option. “That is absolutely disgusting,” Leslie Pugliese argued. A local grandfather said it’s not that serious and lets his granddaughter go the day without a shower after the pool if she doesn’t want to. “I don’t think it’s a big deal, chlorine is in the pool and they’re clean,” Carl Lalomia explained. It’s a sentiment Dr. Dyan Hes actually agrees with.

"Prevalence of hearing loss is estimated to increase as our population grows older, and we know there are strong associations between uncorrected hearing loss and conditions such as Alzheimer's disease or dementia," lead author Dr. Elham Mahmoudi of the University of Michigan in Ann Arbor told Reuters Health by email.

Past research has linked prolonged sensory deprivation - such as loss of hearing - with social isolation and cognitive decline, the study team notes. Hearing loss has also been tied to depression, anxiety and balance trouble with increased risk of falls.

Using insurance claims data, Mahmoudi's team studied 114,862 people age 66 and older with hearing loss.

"For each patient, data was collected over four years - one year before they were diagnosed with hearing loss, and three years after," Mahmoudi said. "This was done to ensure the patient had not been diagnosed with Alzheimer's disease or dementia, depression or anxiety, and injuries from falls in the year before their diagnosis."

Fatal Kidney Condition Diagnosis Hastened By App

Fatal Kidney Condition Diagnosis Hastened By App Scientists developed a new mobile phone app that works to detect acute kidney injury in minutes compared to traditional methods that commonly take hours.

Many diseases and conditions have their own “breathprint,” and this may soon pave the way for earlier detection and diagnosis. While scent tests to diagnose disease are not quite ready for prime time, research is ongoing, says Dr . Hirsch, also the author of several books including Nutrition and Sensation.

Body odour can be a sign of more than just someone forgetting to put on their deodorant.

Only 12.3% of the study subjects used hearing aids, the authors found. Hearing aid use was more common among men (13.3%) than women (11.3%), and among non-Hispanic whites (13.6%) compared to black (9.8%) or Hispanic (6.5%) people.

The gender and race differences are significant, the authors note, because the cognitive conditions being studied are more common among women than men, and among African-Americans compared to whites.

Hearing aid use was highest in north-central states at almost 37%, and lowest, at 6%, in the mountain states.

While everyone in the study had health insurance, hearing aids are typically not covered or only partly covered, and the cost falls on the individual, the study team points out. On average, hearing aids cost between $2,000 and $7,000.

"We not only need to advocate for insurance coverage for hearing aids, but also educate the public about the risks of uncorrected hearing loss," Mahmoudi said.

‘Super Smeller’ Grandmother Can Detect Parkinson’s Disease by People’s Scent

‘Super Smeller’ Grandmother Can Detect Parkinson’s Disease by People’s Scent The 68-year-old, from Scotland, said she’s always noticed when her patients’ smell would change during her years as a nurse. “They say [my nose is] somewhere between a dog and a human. And I take that as a compliment,” Milne said on the Today show. Her extra-sensitive sense of smell was the first to notice, decades ago, that something was wrong with her husband. All of a sudden he started smelling off. “He was only 31, going on 32, it was that summer. I thought, well, I’m not going to nag about this,” she said. Then, a little over a decade later at age 45, he was diagnosed with Parkinson’s disease.

The aging U.S. population makes this study significant, noted Dr. Linda McEvoy of the University of California, San Diego, who wasn't involved in the research.

The study lacked data on patients' education levels, socioeconomic status or lifestyle that could influence the risks for dementia and other study outcomes. This, McEvoy said, is an important limitation.

"If hearing aid users in the current study have higher levels of education than non-users, then some of the protective associations of using the aid may be the effect of education, not the hearing aids," McEvoy said in an email.

The study wasn't designed to determine how hearing aids might reduce risk for physical and mental decline, and randomized clinical trials to test if hearing aids have this protective effect are needed, the study team notes.

Until then, Mahmoudi believes, it would help to make hearing aids more affordable.

"Beyond the costs, low prevalence of hearing aid use has been linked to complexity of the hearing-care system in the U.S., stigma, and poor perceived benefit and need," she said. "People also do not have a single point of contact."

Utah Teen Put in Coma After Vaping Every Day for 3 Years

Utah Teen Put in Coma After Vaping Every Day for 3 Years Maddie Nelson developed a rare lung illness called acute eosinophilic pneumonia. "When you inhale [while vaping], the moisture is creating the perfect environment for bacteria to grow inside your lungs and for infection to start," she recalled her doctors saying. Doctors treated Nelson with a course of steroids and she immediately started to improve. She was brought out of the coma three days later, her siblings wrote.

We can only use our smelling sense to detect useless things. Vianna: 2 Schizophrenia Schizophrenics have difficulty identifying odors, and problems with the sense of smell seem to be linked with the disease .

Animals are using their smelling ability to detect so many things like heat period, presence of prey, recognition and even detection of human sickness by cats. But we humans have useless this ability. We can only use our smelling sense to detect useless things.

Although hearing aids are expensive, she noted, "the costs of the conditions they could prevent or delay are substantially more expensive."

McEvoy agrees.

"The costs of caring for cognitively-impaired older adults are high. If hearing loss contributes to that risk, then hearing aids may be an easily implemented solution to reduce some of that burden on our healthcare system."

a group of people preparing food in a kitchen: You might feel silly, but unleashing your inner pop star and belting out some music while practicing your moves can make you feel years younger. “Simple acts like singing and dancing to your favorite music can keep you young,” Yoon says. “I listen and dance to a wide range of music, from ’70s music to pop. Singing strengthens muscles in the airway, which improves lung function and mental alertness by delivering more oxygen to the brain. Plus, it’s just so fun.”
