Can't leave your house without your earphones, airpods or headphones? Well, you aren't alone. There are millions of others who feel the same. However, do not be surprised if I tell you that it may lead to memory loss and dementia. According to the National Library of Medicine, the auditory nerve, which carries sound signals to the brain, when constantly bombarded with loud noises, starts transmitting weaker signals. This forces the brain to work harder to interpret the sound, leading to cognitive overload. Prolonged cognitive strain can eventually pave the way for dementia and memory loss.

Long-term headphone use also affects brain function directly. High decibel levels of noise can damage the insulation of nerve fibres that carry auditory signals to the brain, disrupting the flow of information. Moreover, the electromagnetic waves produced by headphones have been linked to problems like headaches, fatigue, and, in some cases, neurological discomfort.

Beyond The Brain, Headphones Can Make You Deaf

Empirical evidence shows that nearly one billion young people are at risk of hearing loss due to excessive exposure to loud music through headphones. For the uninitiated, sound intensity is measured in decibels. Prolonged exposure to noise above 85 decibels can be harmful to hearing. Music listened to at maximum volume using headphones often falls in the range of 85 to 120 decibels, a level capable of causing significant hearing damage over time.

Studies Show The Ill Effects

According to a recent survey in the UK, a staggering 65% of students admitted to listening to music at maximum volume through their headphones. A similar study revealed that adolescents exposed to high noise levels via headphones in noisy environments experienced a hearing loss prevalence of 22.6%. Those who used earphones for 80 minutes or more per day had a hearing loss prevalence of 22.3%. These figures are alarming, especially given how ingrained headphone use has become in daily life.

The ramifications of early-onset hearing loss go far beyond damaged ears. It can also jeopardize your mental health. Hearing loss in youth can set off a chain reaction, leading to social isolation and depression. Over time, it can also escalate and jeopardise your relationships. Ill-fitting headphones add to the woes, causing pain that extends from the inner ear to the jaws and top of the head. They can also lead to ear infections, which eventually hamper cognitive functions.

Protecting hearing and brain health requires a shift in listening habits. Experts recommend keeping the volume below 60 per cent and limiting usage to 60 minutes per day. Investing in noise-cancelling headphones can also help reduce the need to crank up the volume in noisy environments.

Heart clips—also referred to as heart valve clips—are part of a minimally invasive medical procedure known as Transcatheter Edge-to-Edge Repair (TEER). Designed to repair leaking heart valves without open-heart surgery, this advanced treatment restores proper blood flow, relieves debilitating symptoms, and helps patients return to their daily lives.

Understanding Valve Leakage and Symptoms

The heart's valves rely on thin flaps of tissue called leaflets to regulate blood flow.

• The mitral valve (located on the left side of the heart) typically has two leaflets.

• The tricuspid valve (located on the right side of the heart) usually consists of three leaflets.

When a valve is leaking, the leaflets fail to close completely, leaving a gap. Blood leaks backward through this opening toward the lungs, increasing lung pressure and directly causing chronic breathlessness and fatigue.

How the Clip Repair Procedure Works

During a Transcatheter Edge-to-Edge Repair, cardiologists repair the valve using a tiny clip delivered through the vascular system:

1. Catheter Access: Guided by continuous echo imaging, doctors insert a catheter into a blood vessel in the groin and navigate it directly to the heart.
2. Targeting the Valve: The catheter goes to the left side of the heart for a mitral valve repair or to the right side for a tricuspid valve repair.
3. Identifying the Leak: Imaging pinpoints the exact spot where the leaflets fail to seal.
4. Deploying the Clip: The doctor positions and deploys the clip across the leaking gap, grasping the two opposing leaflets and pulling them closer together.
5. Evaluating the Seal: Before releasing the clip completely, doctors perform an echocardiogram to confirm that the clip is strongly anchored, that the backward leak is fixed, and that the risk of clip detachment (embolization) is negligible.

Immediate Relief and Long-Term Healing

Once the clip brings the leaflets together, backward leakage stops immediately, allowing the entire volume of blood to pump forward as intended.

• 24-Hour Recovery: Pressure inside the lungs drops rapidly once the leak is sealed. Many patients notice a dramatic improvement in their breathing within 24 hours of the procedure.

• 3 to 6 Month Integration: Over a period of three to six months, surrounding heart tissue naturally grows over the clip (endothelialization), permanently integrating it into the heart structure.

Smooth Hospital Stay and Recovery

Because the procedure is catheter-based rather than open-chest, patient recovery is remarkably swift:

• In-Room Extubation: Patients are taken off the ventilator right on the procedure table.

• Minimal Closure Site: The groin entry point is closed cleanly using specialized sutures (such as ProGlide or a figure-of-eight suture).

• Quick Discharge: Patients typically spend just one day in the Intensive Care Unit (ICU) before moving to a standard room, after which they can return home and resume normal daily activities.

Frequent cannabis use may worsen epilepsy-related symptoms, new research. It discovered that raised that people with drug-resistant epilepsy who used cannabis often had more frequent convulsive seizures and sought advanced epilepsy care much sooner than non-users.

Published in Epilepsia, the study analysed health records of 64 adults with drug-resistant epilepsy. It found that frequent cannabis users reached an intensive epilepsy monitoring stage an average of five years after their first seizure, compared to 18 years reported among non-users.

The difference of 13 years is attention-worthy but it must be noted that the study shows an association, not proof that cannabis worsens epilepsy.

Seizures Doubled In Cannabis Users With Epilepsy

Researchers compared 22 people who used cannabis at least 20 days a month to 42 people who did not.

The frequent users reported to have a heavier burden of seizure, one of the symptoms of epilepsy. They had more than twice as many convulsive seizures per year than non-users.

About 91% of frequent cannabis users experienced convulsive seizures, compared to roughly half of the non-users.

Seizures involve stiffening and jerking of the body and loss of consciousness. They constitute medical emergency as they are associated with sudden death in epilepsy.

What Does Drug-Resistant Epilepsy Mean?

Epilepsy is considered drug-resistant when seizures continue despite appropriate treatment with two antiseizure medications.

People with drug-resistant epilepsy may need to visit specialised epilepsy centres, where doctors can monitor them and recommend changes in medication, surgery, or other treatment options. In this study, frequent cannabis users reached this stage much earlier.

They were also discharged from hospital after taking an average of 3.05 antiseizure medications, compared with 2.21 among non-users.

Cannabis & Epilepsy

This was a retrospective study based on health records of a small sample size. There may be other differences between people who used cannabis often and those who did not that could affect the severity of the seizures.

However, researchers were able to establish the timing of cannabis use for 15 of the 22 users. All 15 had started using cannabis before their first seizure, making it less likely that they had simply begun using cannabis to cope with an already existing seizure disorder.

The researchers say larger studies can determine whether cannabis contributes to worsening seizures.

The association between cannabis and seizures is complicated as CBD (cannabidiol) is reported to have beneficial effect on severe epilepsy.

To understand the seeming contradiction, we must understand the distinction between cannabis and purified cannabidiol (CBD).

A purified form of CBD is an approved treatment for certain severe forms of epilepsy. CBD is different from THC, the psychoactive element responsible for the “high” associated with cannabis. Recreational cannabis products may contain high concentrations of THC.

According to the researchers, animal studies suggest CBD can suppress seizures, while THC may have the opposite effect.

Hence, evidence that a specific CBD-based medicine can help certain epilepsy syndromes cannot be used to conclude that recreational cannabis is an epilepsy treatment.

Researchers suggest that THC acts on receptors concentrated in brain regions involved in seizures, raising the possibility that cannabis could influence how brain circuits fire. But this is a hypothesis that needs further investigation.

A stroke changes the life of a person in an instant, making everyday activities like walking, talking, or even holding a cup difficult. But strokes do not always mean these challenges are permanent. Many people recover lost abilities and enhance their lives with timely treatment, proper rehabilitation and continued support.

A stroke occurs when blood stops flowing to the brain or a blood vessel in the brain bursts, cutting off oxygen to brain cells. It can cause weakness or paralysis, speech problems, poor balance, or memory issues, or trouble swallowing, depending on the part of the brain that is affected.

Tips to Support Recovery from Stroke

• Begin rehabilitation immediately after a stroke
• Attend Physiotherapy and speech Therapy sessions regularly
• Take prescribed medications as directed.
• Keep blood pressure, diabetes and cholesterol under control.
• Have a healthy and nutritious diet to restore energy.
• Stay physically active
• Seeking emotional and psychological support

The Treatment Journey:

Timely Medical Care Makes a Big Difference

Patients who reach the hospital within a certain time may be eligible for clot-busting medications or clot removal procedures. These procedures restore blood flow, reduce brain damage and increase the likelihood of faster recovery.

Rehabilitation starts immediately after stroke

Stroke care extends beyond emergency treatment. Rehabilitation begins within 24 hours after a stroke when the patient is medically stable. A team of specialists, including neurologists, physiotherapists, and speech therapists, works together to help the patient regain function, rebuild confidence and return to everyday activities as soon as possible.

Physical Therapy to Rebuild Body Movement and Independence

When a stroke happens, muscles on one side of the body may become weak or paralysed, affecting the patient's strength, balance, coordination, posture, and walking.

Physiotherapy consists of a series of exercises, muscle training and mobility techniques that enhance mobility of the body and improve functional independence. Many patients can perform activities with greater ease with regular rehabilitation.

Enhancing communication and cognitive skills

After a stroke, some patients have problems talking, speaking, swallowing, remembering or concentrating. Speech and language therapy are used to help with communication and safe swallowing, and cognitive rehabilitation is used to support memory, attention, reasoning and problem solving. These therapies assist patients in re-entering the workforce, social circles and independent living more smoothly.

Modern Rehabilitation Methods for Better Recovery

Advances in rehabilitation have expanded the range of therapies available to support stroke recovery.

Techniques like robot-assisted rehabilitation, functional electrical stimulation (FES), virtual reality-based therapy, constraint-induced movement therapy, balance training systems and computer-assisted gait training complement conventional rehabilitation very well. These methods provide repetitive, targeted exercises that promote functional improvement in the brain and body.

Managing Ongoing Challenges

After a stroke, some patients have muscle stiffness (spasticity), chronic pain or trouble walking or moving their hands. They are treated with medications, injections and continued rehabilitation therapy.

Recovery from a stroke is much better with proper rehabilitation. While some regain most of their abilities, others continue to need support, making patience and consistency just as important as medical help. The right care at the right time makes a big difference in rebuilding your life.
