Many diseases share the same symptoms, causing people to get confused and either undermine or overwhelm themselves with worries. With the current flu season on the rise, people in the United States are being very careful about their health and are taking necessary precautions to make sure they do not catch any more respiratory illnesses. Often these diseases show symptoms like coughing and wheezing, nothing that warrants anything more than a general doctor’s visit, sometimes people even think it it is a simple cold, but it could be something worse!

The Centers For Disease Control and Prevention (CDC) report on 28 February, last Friday on Respiratory Virus Activity Levels reported a moderate number of people are seeking medical help for respiratory illnesses. The flu is sending many people to the emergency room, RSV Respiratory syncytial virus has been sending many people to the ER along with COVID-19.

While flu test results are slightly less positive than last week, COVID-19 and RSV test results are about the same. In our community's wastewater, the flu virus is still very high, COVID-19 is moderate, and RSV is low. Looking forward, we expect COVID-19 emergency room visits to stay low. While flu visits are still high, they should start to go down soon.

So, even though it might feel like winter is ending, these viruses are still active, and we need to be careful. They are not going away quickly and can still spread easily. Here are some symptoms that should be treated with urgency right now.

Severe Dehydration

When you're really sick, you might not feel like eating or drinking. This can lead to dehydration, which is when your body doesn't have enough water. If your pee is dark yellow, or you feel dizzy, you might be dehydrated. If you pass out, get confused, or your heart beats really fast, you need to go to the hospital right away. Healthcare professionals can give you fluids through a needle to help you feel better. Being dehydrated is very dangerous, and it is important to take it seriously.

Breathing Difficulties

If you're having trouble breathing, or if you're breathing really fast, that's a big sign. It could mean that you have pneumonia or that your body isn't getting enough oxygen. Shortness of breath is always a reason to go to the emergency room. Your body is telling you that something is seriously wrong. It is very important to seek help right away. Do not wait it out at home.

Low Oxygen Levels

If your lips or fingers start to turn blue, that means you're not getting enough oxygen. Also, if you're so tired that you can barely get out of bed, that's another sign that you need to go to the hospital. These are serious symptoms that mean your body needs help right away.

Who’s Most at Risk for Severe Symptoms?

Some people are more likely to get very sick from these viruses. Pregnant people, little kids, and older adults are at higher risk. Also, people who have health problems like heart or lung disease, or people with weak immune systems, are more likely to have serious problems. Older adults are often hospitalized with the flu, COVID, and RSV. These groups need to be extra careful to avoid getting sick. It is very important that these groups get vaccinated.

RSV is especially dangerous for babies and young children. It's one of the main reasons why young kids end up in the hospital. This virus can make it very hard for them to breathe. It is very important to protect young children from this virus, especially in the first few years of their lives.

What if the body whispers long before it screams? For many living with Parkinson’s disease, the earliest signs are not the tremors, but quieter changes, such as a diminished sense of smell, disrupted sleep, or gut problems. The challenge is that we are conditioned to look for the disease only once it becomes visible.

Parkinson’s disease, commonly referred to as a movement disorder, progresses slowly due to the destruction of the nerve cells in the brain.

To understand Parkinson’s disease, think of the brain as a command center where certain nerve cells produce dopamine, a chemical messenger that helps coordinate smooth movement. As these dopamine-producing cells gradually deteriorate, the brain’s signalling system gets disturbed, leading to slower movements, mistaken for normal ageing.

The majority of patients experience subtle early signs much before diagnosis, including a reduced sense of smell, sleep disturbances like insomnia, and persistent digestive problems like constipation. In these cases, timely intervention can reduce movement disability by roughly 40 percent.

Conventional treatment focuses on medications that boost dopamine levels, but over time, their effectiveness may decline. When drugs are no longer sufficient, doctors may recommend Deep Brain Stimulation (DBS), a surgical approach that works like a pacemaker for the brain and uses chest-connected electrodes to reset faulty signals causing stiffness and tremors.

Unlike fixed traditional stimulation, the advanced Adaptive DBS (aDBS) listens to brain signals in real-time to adjust therapy automatically. Its single threshold mode reacts instantly, boosting stimulation the moment brain signals hit a specific limit and turns it off just as fast once they improve.

Alternatively, its double threshold mode keeps stimulation steady within the safe zone," making only gradual tweaks if signals cross upper or lower limits. This smart system mimics the body’s natural rhythm to provide fluid symptom control while preventing overstimulation, ultimately helping you reclaim more "good" time and independence.

Parkinson’s Diet

There is no single ‘Parkinson’s diet,’ but certain food choices can help manage symptoms and overall well-being. A balanced diet rich in fruits, vegetables, and whole grains supports general health and may help reduce inflammation.

Plant-based flavonoids, present in berries, citrus fruits, and broccoli, which have antioxidant effects, can help protect brain cells from damage. Drinking enough water can support digestion and prevent dehydration.

Ultimately, small, consistent dietary choices, combined with medical guidance, can make a meaningful difference in managing symptoms.

Parkinson’s disease is a journey, and the earlier the signs are recognized, the better the condition can be managed. If you or a loved one is experiencing persistent changes in sleep, smell, or movement, do not wait for the symptoms to become overwhelming. Consulting a neurologist is the first step toward taking back control of your health.

While salt, cholesterol, and obesity are major factors driving high blood pressure, a recent study suggests they may not be the only causes.

Researchers from Brazil and New Zealand have identified a brain region that may increase the risk of hypertension. The study, published in the journal Circulation Research, showed that the brain region called the lateral parafacial region is the culprit.

The lateral parafacial region sits in the brainstem – the oldest part of the brain – which controls automatic functions such as digestion, breathing, and heart rate.

“The lateral parafacial region is recruited into action, causing us to exhale during a laugh, exercise, or coughing,” said lead researcher Professor Julian Paton, from the Centre for Heart Research at Waipapa Taumata Rau, University of Auckland.

“These exhalations are what we call ‘forced’ and are driven by our powerful abdominal muscles. In contrast, a normal exhalation does not need these muscles to contract; it happens because the lungs are elastic,” Paton added.

Can Breathing Patterns Signal Hypertension?

Paton and the team found that the lateral parafacial region also connects to nerves that tighten blood vessels -- a mechanism that raises blood pressure.

“We’ve unearthed a new region of the brain that is causing high blood pressure. Yes, the brain is to blame for hypertension!” Paton said.

“We discovered that, in conditions of high blood pressure, the lateral parafacial region is activated and, when our team inactivated this region, blood pressure fell to normal levels.”

The team explained that this means changes in breathing patterns – especially those involving strong abdominal muscle contractions – can trigger high blood pressure. Thus, any diagnosis of abdominal breathing in patients with high blood pressure may reveal the cause and hence direct appropriate treatment.

Can The Brain Region Help Treat Hypertension

The next question was whether the brainstem region could be treated with a medication.

“Targeting the brain with drugs is tricky because they act on the entire brain and not a selected region such as the parafacial nucleus,” Paton said.

The researchers then discovered that this region is activated by signals from outside the brain – from the carotid bodies, tiny clusters of cells in the neck near the carotid artery that sense oxygen levels in the blood.

These can be targeted safely with medication, they said.

“Our goal is to target the carotid bodies, and we are importing a new drug that is being repurposed by us to quench carotid body activity and inactivate ‘remotely’ the lateral parafacial region safely, i.e., without needing to use a drug that penetrates the brain.”

This finding could lead to new treatments for high blood pressure, especially for people who also have sleep apnea, as we know carotid bodies are activated in these patients when they stop breathing at night.

Global Burden Of Hypertension

Hypertension is commonly referred to as the "silent killer" due to its lack of noticeable symptoms. Unchecked, it progressively damages your arteries and vital organs.

It occurs when the pressure in your blood vessels is consistently higher than normal—usually 140/90 mmHg or more, states the World Health Organization (WHO). The normal and healthy level is estimated to be 120/80 mmHg. Blood pressure increases when the arteries get narrow or stiff, causing the heart to work harder.

At a global level, an estimated 1.28 billion adults aged 30 to 79 years have hypertension, and most of them live in low- and middle-income nations. Alarmingly, 46 percent of them do not even know they have it, and just 1 in 5 keeps it under control, as per WHO statistics.

In the US alone, the Centers for Disease Control and Prevention (CDC) estimates that nearly 47 percent of adults, or roughly 116 million individuals, have hypertension, yet only 24 percent control it well. The economic burden is just as overwhelming, with the US spending $131 billion each year on care related to hypertension.

Exercise, lifestyle changes, and diet are key to preventing hypertension

Alzheimer's disease is one of the most common forms of dementia, causing 60-70 percent of cases. It mostly affects adults over the age of 65 and is a leading cause of death and disability.

A new study has shown that the disease can be prevented in more than half of the older adults at risk with the commonly advised flu vaccination.

The research from the University of Texas Health Houston showed that a higher dose of the influenza vaccine is key for reducing the chances of developing Alzheimer’s.

Although previous research showed the protective effect of influenza vaccine against Alzheimer’s, the new findings showed that its benefits lie with a higher dose of the influenza vaccine.

The US CDC recommends adults 65 and older to receive a high-dose flu vaccine. It is because the immune system becomes less effective at fighting infection at the age of 65. The regulator advises a four times stronger dose to the elderly population than the standard dose given to the general population.

The analysis on nearly 200,000 participants ages 65 and older, both men and women, revealed that a higher-dose of influenza vaccination reduced the risk of Alzheimer’s by nearly 55 percent compared to 40 percent with standard-dose vaccination. The results also showed that the protective effect of the high dose was stronger among women.

Other Vaccination And Alzheimer’s Risk

While it is not proven, a hypothesis about the link between vaccination and reduced risk of neurodegeneration is that inoculation strengthens immune defenses while dampening inflammation.

Inflammation is thought to play a role in the development of Alzheimer’s disease.

“Enhanced [flu vaccines] confer greater protection against influenza infection, thereby decreasing risk of severe illness and the associated systemic inflammation that can promote neuroinflammation and neurodegeneration,” the researchers said.

Recent research has also linked the shingles vaccine to slowed neurodegeneration and decreased risk of dementia. The study led by Oxford University researchers showed that shingles vaccine reduces lowers the risk of developing a new dementia diagnosis by 17 percent to 20 percent.

Further, it noted that the vaccine may act along the entire clinical course, potentially delaying mild cognitive impairment (MCI) and even slowing the disease in those already living with dementia.

“The evidence is not nearly as strong as the four natural experiments with [the] shingles vaccines. But if true, it is likely working via stimulating the immune system, raising its functionality in older adults who are prone to immunosenescence,” Eric Topol, MD, professor and executive vice president at Scripps Research, told CIDRAP news. Immunosenescence refers to the gradual deterioration of the immune system that occurs with aging.

What Is Alzheimer’s Disease?

About 8.8 million Indians aged 60 and above are estimated to be living with Alzheimer's disease. Over seven million people in the US 65 and older live with the condition and over 100,00 die from it annually.

Alzheimer's disease is believed to be caused by the development of toxic amyloid and beta proteins in the brain, which can accumulate in the brain and damage cells responsible for memory.

While there is no clear cause of Alzheimer's disease, experts believe it can develop due to genetic mutations and lifestyle choices, such as physical inactivity, unhealthy diet and social isolation.

Early symptoms of Alzheimer's disease include forgetting recent events or conversations. Over time, Alzheimer's disease leads to serious memory loss and affects a person's ability to do everyday tasks.

There is no cure for this progressive brain disorder and in advanced stages, loss of brain function can cause dehydration, poor nutrition or infection. These complications can result in death.
