We often think of anxiety as an emotional or mental struggle- a racing heart before a big meeting, a persistent knot in the stomach, the endless loop of worst-case scenarios playing out in our minds but what if anxiety was doing more than just weighing on your mood? What if, over time, it was actually damaging your brain?
Chronic anxiety, if left untreated, doesn't just affect how you feel. Emerging neuroscience suggests it can also cause structural and functional damage to the brain, potentially speeding up the onset of neurodegenerative diseases like Alzheimer’s and Parkinson’s.
According to Dr. Prajwal Rao, DM Neurology and Head of the Department of Neurology at Dr. D.Y. Patil Medical College, Hospital and Research Center in Pune, “We’re starting to view anxiety not just as a symptom of stress or a psychiatric diagnosis, but as a biological driver that may influence long-term brain health.” That insight is leading researchers and clinicians to reevaluate how they screen, diagnose, and treat anxiety—especially in older adults.
This is more than a mental health story. It’s a wake-up call about how your mind and body are more interconnected than we ever realized—and why ignoring chronic anxiety could have irreversible consequences.
At the core of this mind-body connection lies the body’s stress response system, known as the hypothalamic-pituitary-adrenal (HPA) axis. This system is built for short-term survival, it floods your body with cortisol to help you react in fight-or-flight situations. But when anxiety is chronic, the HPA axis stays overactivated, keeping cortisol levels high for too long.
Dr. Rao explains, “Sustained cortisol exposure has neurotoxic effects. It weakens the hippocampus, the area of the brain responsible for memory and learning. Over time, this can lead to measurable cognitive decline.”
This means that someone living with long-term anxiety isn’t just emotionally fatigued—they may also be more vulnerable to diseases involving memory loss, such as Alzheimer’s.
Recent imaging studies support what neurologists like Dr. Rao have long suspected. People with generalized anxiety disorder (GAD) frequently show reduced hippocampal volume, a condition also observed in patients with early-stage Alzheimer’s. These findings suggest a troubling overlap between anxiety-related brain changes and those seen in neurodegenerative diseases.
But the damage doesn’t stop there. Chronic anxiety can also trigger neuroinflammation, the process by which the brain’s immune system begins attacking its own cells. Neuroinflammation has been implicated in a wide range of neurological diseases—from Parkinson’s to ALS—raising the stakes for early anxiety treatment.
Another hidden piece of the puzzle is sleep. The brain’s self-cleaning system, known as the glymphatic system, becomes active primarily during deep sleep. It flushes out toxic proteins like beta-amyloid, the same proteins that clump together to form plaques in Alzheimer’s patients.
Chronic anxiety often disrupts sleep, reducing both its quality and duration. “When deep sleep is compromised, the brain loses its opportunity to detoxify itself,” says Dr. Rao. “This may allow harmful proteins to build up, accelerating cognitive decline.”
While not everyone with anxiety will develop a neurodegenerative disease, some individuals may be more biologically susceptible than others. Genetics appears to play a role—especially in people who have both anxiety-prone temperaments and gene variants that affect stress response and neural resilience.
These individuals may have a double disadvantage, they’re more likely to experience anxiety, and their brains may be less equipped to handle the long-term effects of that stress. Early screening and intervention in such high-risk populations could be crucial in delaying or preventing serious brain-related illnesses.
One of the most concerning aspects of this connection is how frequently anxiety is underdiagnosed in older adults. Symptoms like restlessness, irritability or sleep problems are often written off as “normal aging” especially when there’s no obvious cause.
This is a missed opportunity, says Dr. Rao. “Anxiety in the elderly shouldn’t be dismissed—it may be a modifiable risk factor for neurodegeneration. By treating it proactively, we’re not only improving emotional wellbeing but potentially preserving cognitive function.”
Treating anxiety isn’t just about feeling better in the moment—it could be a long-term investment in your brain health. Cognitive-behavioral therapy (CBT), mindfulness-based stress reduction, physical exercise, and even certain medications can all help manage anxiety. But more importantly, they may help protect the brain from premature decline.
“It’s time we stop thinking of anxiety as just an emotional burden,” Dr. Rao says. “The brain and body are intimately connected. Supporting mental health is supporting brain health—and ultimately, whole-body health.”
As neuroscience continues to evolve, one truth is becoming clear: our emotional health is not separate from our physical wellbeing. Chronic anxiety, if left unchecked, may do more than drain your energy or mood. It may slowly erode the very structure of your brain.
The next time you’re tempted to push anxiety to the side or power through it, remember this—the mind can break the body. But with the right care, attention, and treatment, it can also be the first line of defense in protecting your most vital organ: your brain.

Step into a busy OPD, and you will see it: people coughing but not paying much attention. Tuberculosis is still around, just quietly spreading. By 2024, one out of every four global TB infections was recorded in India.
More than a number, each case hints at missed chances, tiny failures in spotting or stopping the disease that swell into widespread strain.
In earlier times, TB was common and very hard to recover from. Crowded homes, lack of fresh air, and low income open doors for germs to move fast. When hunger weakens people too, their bodies fail to hold back hidden sickness. But that is only part of what happens now. Conditions like smoking, drinking, high blood sugar, or HIV have slipped into view, tying daily habits closely to how often TB strikes.
After that, finding the right treatment can feel like a struggle. Some people start by visiting private clinics, shifting between different doctors until they finally learn what is wrong. Every wait means more time lost, moments when illness keeps growing without check.
Adults in their prime work phase feel it most. Males, particularly over the age of fifteen, carry heavier loads - a pattern the World Health Organization keeps pointing out. Yet biology alone doesn’t explain it.
Who shows up for treatment, who waits too long, who gets missed entirely, it's all written into the pattern. Older people, men, and anyone struggling with poor nutrition, using tobacco, or living with diabetes, show up more often in India’s national health data. The numbers tell a consistent story.
Here’s what happens. Tuberculosis usually shows up too late. Close to 60 percent of those feeling sick skip early help. Ongoing cough, body heat, weight loss, and night sweats are early signs. Some self-treat. For many, money becomes a barrier. Then comes the expected outcome - severe illness, tougher treatments, more time healing.
Still, false beliefs hang on. Air carries TB, not hands. Passing a meal does not pass the disease, yet shame can hold someone back from care. Cough that won’t quit, rising heat in the body, pounds slipping away, sweat at night - these hints show up early but get ignored till chances shrink.
Fighting TB in India isn’t only about medicine; it lives in habits, choices, and how people see illness. If getting help fast stays rare instead of routine, the disease keeps moving quietly through packed houses, buzzing health rooms.

Today, the fitness scene has gained much traction among the Gen Z population. With more and more young people spending time in the gym and working out, it is important for fitness enthusiasts to remember the importance of leg stiffness and its impact on spine health. Leg stiffness has the potential to cause unnecessary strain on the spine and back during workouts.
From a neurosurgical point of view, we see that the spine is not just a mechanical support structure but a sensitive pathway through which the spinal cord and nerve roots run. Repeated micro-strain caused by poor flexibility can cause young patients to suffer early degenerative changes that may cause nerve irritation.
We also see that strengthening the abdominal muscles is essential in stabilizing the spine, thereby preventing disc injuries. Early intervention in minor complaints, such as back stiffness or nerve pain, is essential in preventing more serious problems that may need surgical intervention.
The muscles in your legs are important for your spine's health. The hamstring, hip flexor, and calf muscles are all significant players in the movement and positioning of your spine. Leg stiffness has the potential to cause unnecessary strain on the spine and back. Leg stiffness limits the movement and positioning of the hips and the spine.
When these muscle groups are tight, they alter pelvic alignment and increase load on the lumbar spine. Over time, this abnormal biomechanics can lead to disc stress and facet joint overload.
In neurosurgical practice, we often see young patients presenting with early symptoms of nerve compression where underlying muscle imbalance and stiffness play a contributory role.
For young people, the main focus in the gym is on strength training, while flexibility and rest are ignored. This makes the condition of the legs stiffer. Another common error is improper posture while performing certain exercises in the gym. When the legs and hips are inflexible, proper posture is difficult, which causes pressure on the spine.
Sitting for a long time, studying, playing games on gadgets, etc., causes the hip flexors and the hamstring muscles in the legs to become stiffer, which causes pressure on the spine.
From a clinical standpoint, improper lifting techniques combined with stiffness can increase the risk of lumbar disc prolapse and nerve root irritation, conditions frequently encountered in spine clinics.
Additionally, from a neurosurgical perspective, core strengthening plays a crucial role in stabilizing the spine and reducing the risk of disc-related injuries. Early attention to minor symptoms like back stiffness or radiating pain can prevent progression to more serious conditions requiring intervention.
Common spine problems to avoid during gym workouts include Herniated Disc, Sciatica, Spondylolisthesis, and Muscle Strain. These can occur from poor form, heavy lifting, or lack of warm-up.
In advanced cases, such conditions may lead to nerve compression requiring specialized evaluation and, rarely, surgical management. However, most of these issues are preventable with correct technique and conditioning.
Fitness enthusiasts in the Gen Z generation need to understand that it is very important to develop strength in the body while at the same time maintaining flexibility. The solution to the problem of a stiff leg is the foundation of protecting the spine and improving workout performance. This is achievable through the right warm-up, correct workout, and correct lifting.

A recent meningitis outbreak in Kent University has led to many people wandering about the MenB vaccine and whether they should be getting it. The UK Health Security Agency (UKHSA) with NHS England and the government is already coordinating a targeted vaccination programme against Meningitis B- the strain identified to cause the outbreak.
As per UKHSA, anyone in the following group has been offered preventative antibiotics which is also known as prophylaxis, is being offered the MenB vaccine. As of now, this includes:

As of now, notes UKHSA that the risk of infection to the wider public remains low. This is because transmission of MenB requires close and prolonged contact to spread. This could only happen when people are living in the same household and with intimate contact such as kissing or sharing drinks or vapes.
The bacteria, notes UKHSA, are not as contagious as the other infections like measles and COVID 19.
Antibiotics play an important role, and almost an immediate one when it comes to responding to an outbreak. For anyone who has been in close contact with a confirmed or suspected case, preventative antibiotics are being offered to them to clear any meningococcal bacteria they may be carrying. This will reduce the risk of them becoming ill or passing the bacteria on to others.
The simple answer is a yes. UKHSA notes that if you are eligible for the MenB vaccine despite the fact that you have taken MenACWY vaccine, you should come forward and take the MenB vaccine. This is because the MenACWY vaccine does not protect you against the MenB strains, as they are both different strain. MenB has been identified as the primary cause of meningitis outbreak in Kent University.
