Every year on September 21, World Alzheimer's Day is observed. It is a global effort to raise awareness and challenge the stigma around Alzheimer's disease and other dementia.

Alzheimer's is a severe brain disorder of memory loss and confusion. If it is not diagnosed and managed on time, it can also adversely impact one's mental abilities of learning, thinking, reasoning, remembering, problem-solving, decision-making, and attention.

Every year, a particular theme is followed, this year, the theme is "Time to act on dementia, Time to act on Alzheimer's".

The theme focuses on attitudes towards dementia and addresses the stigma and discrimination that still exists. Some of the common attitudes towards dementia are the common belief that dementia is a normal part of ageing, with 62% of healthcare practitioners actually believing it to be true. 35% of carers had hidden a diagnosis of dementia and 1 out of 4 thought that nothing could be done about it.

History

The first time this day was introduced was in 1994 in Edinburgh, on the occasion of the 10th anniversary of Alzheimer's Disease International (ADI). This organisation was founded in 1984 to support and guide Alzheimer's disease patients and their families.

The organisation also runs Alzheimer's University and aims to connect people around the world to promote Alzheimer's Month, which is also celebrated in September.

What Is Dementia, What Is Alzheimer's?

As per Neha Sinha, Dementia Specialist, CEO and Co-founder of Epoch Elder Care, it is a progressive decline in cognitive abilities, including memory, language, problem-solving and other thinking skills. It is severe enough to interfere with daily life. "It primarily affects older adults, with Alzheimer's being the most common," she says.

Alzheimer's accounts for 60 to 80% of all dementia cases around the world. It is estimated that the prevalence of Alzheimer's worldwide is around 2.4 crores.

While Dementia is the general term for a range of symptoms that affect cognitive abilities, while Alzheimer's is the most common form of dementia.

Shilpi Saraswat, Clinical Psychologist at Sakra World Hospital, Bengaluru points out that the main risk factors of dementia are age, genetics, long-term health conditions, lifestyle choices such as smoking or excessive alcohol use, one's gender and cognitive reserve.

Dementia In Indian Household

Sinha points out that in India, the subtle onset of dementia is quietly emerging as a silent epidemic, affecting millions of households across the country. As per the Neurological Health Atlas of India, 8.8 million elderly are currently living with dementia. "A number that can be doubled by 2036," says Sinha.

Sinha also points out that since its earliest symptoms are often ignored as signs of early ageing, Dementia stays ignored and creeps into the household unnoticed.

"Discovering Alzheimer’s early can be a pivotal moment, offering a window of opportunity that changes the course of the disease. With an early diagnosis, we can initiate medical treatments and a management plan, that may slow down the progression, giving patients and their loved ones more quality time together," says Sinha.

When care is tailored to the person, not just the disease, it profoundly enhances their quality of life. It’s about more than just managing symptoms—it’s about nurturing emotional well-being, maintaining dignity, and providing the support that adapts as the disease evolves.

Can Hearing Loss Lead To Dementia?

While age is one of the risk factors in dementia, Dr Sanjay Sachdeva, a senior ENT at HearClear India suggests a link between hearing loss and dementia.

As per a study by the Lancet Commission on Dementia, untreated hearing loss can give rise to greater cognitive decline and even account for approximately 8% of dementia cases worldwide. This means, 8 lakh of the nearly 1 crore new cases of dementia are diagnosed every year.

"Considering that auditory information plays a pivotal role in forming memories and associations, hearing impairment interferes with the brain’s ability to process auditory information, which consequently deteriorates memory and learning abilities," says Dr Sachdeva. Additionally, hearing loss in ageing people can go beyond the inability to hear things and can contribute to social isolation in them.

What Can Help Reduce It?

Saraswat point out that by modifying 12 risk factors through lifestyle changes, 40% of the dementia cases can be delayed.

Some of the specific actions include maintaining systolic BP of 130 mm Hg or less in midlife from around age 40 years (antihypertensive treatment for hypertension is the only known effective preventive medication for dementia).

Encouraging the use of hearing aids for hearing loss and reduce hearing loss by protecting of ears from excessive noise exposure.

Other such prevention methods include:

• Reduce exposure to air pollution and second-hand tobacco smoke.
• Prevent head injury.
• Limit alcohol use, as alcohol misuse and drinking more than 21 units weekly increase the risk of dementia.
• Avoid smoking uptake and support smoking cessation to stop smoking, as this reduces the risk of dementia even in later life.
• Provide all children with primary and secondary education about brain health.
• Reduce obesity and the linked condition of diabetes. Sustain midlife, and possibly later life physical activity.
• Addressing other putative risk factors for dementia, like sleep, through lifestyle interventions, will improve general health.

The Supreme Court of India, in a landmark decision, authorized the removal of life support for Harish Rana, a 31-year-old man in a vegetative state since 2013.

This marks the country's first Court-approved case of passive euthanasia without a prior living will. The Court ruled that the "right to die with dignity" is a fundamental part of the right to life under Article 21.

Speaking to HealthandMe, the experts said that the landmark ruling will enable families and doctors to make compassionate decisions and may also influence end-of-life protocols.

There are several medical conditions where patients undergo prolonged suffering despite treatment, with no realistic scope for recovery, sometimes for decades.

“This judgment could have a significant impact on end-of-life care practices in Indian ICUs. Many patients remain in prolonged vegetative states with no meaningful quality of life, often sustained only through artificial life support,” Dr. Sandeep Dewan, Senior Director, Critical Care & Chairman ECMO Program, Fortis Gurugram, told this publication.

“The ruling reinforces that while preserving life is important, the quality and dignity of life must also be considered, and it provides clearer pathways for families and doctors to make compassionate decisions in such situations,” he added.

Harish was a BTech student in Chandigarh who suffered severe traumatic brain injury after falling from the fourth floor of his paying guest accommodation in August 2013.

Since then, he has remained bedridden and was being treated with Clinically Administered Nutrition (CAN), where surgically installed PEG tubes helped him with breathing and nutrition.

The apex Court, in its ruling, noted that it can just prolong his biological existence, but it will not lead to any therapeutic improvement.

With the Harish Rana judgment, the apex Court today clarified how passive euthanasia should be applied in cases where a patient’s life is being supported by feeding tubes.

The top Court also waived off the reconsideration period of 30 days and noted that the medical treatment, including the CAN administered to the patient, can be withdrawn or withheld.

"Doctors and hospitals have often been reluctant to stop tube feeding in such patients, fearing that it could be interpreted as 'starving the patient to death',” Dr. Rajeev Jayadevan, Ex-President of IMA Cochin and Convener of the Research Cell, Kerala, told HealthandMe.

“Today’s ruling clarifies that artificial nutrition and hydration are indeed forms of medical treatment. Therefore, withholding such artificial feeding can be considered withdrawal of life-sustaining medical support in situations where treatment offers no prospect of recovery and only prolongs suffering,” he added.

Passive Euthanasia In India

Passive Euthanasia allows a terminally ill or irreversibly comatose patient to die naturally. It involves deliberately withholding or withdrawing life-sustaining treatments (like ventilators, feeding tubes, or medication). It has been legal since 2018, but under strict guidelines.

On the other hand, active euthanasia or assisted suicide for terminally ill patients is legal in several countries, but is not permitted in India.

The Aruna Shanbaug Case (2011) paved the way for passive euthanasia in India.

Shanbaug was a nurse at Mumbai's KEM hospital who remained in a vegetative state for 42 years after an assault in 1973. The hospital staff cared for her and did not stop treatment till she passed away naturally in 2015.

However, in the 2011 Aruna Shanbaug judgment, the SC allowed passive euthanasia by permitting the withdrawal or withholding of life-sustaining treatment under strict legal safeguards.

This framework was further clarified in the 2018 Common Cause judgment, which recognized advance directives or living wills.

Later in 2023, the SC modified the guidelines, noting that withdrawal of life support is permissible only after the approval of the Primary and Secondary Medical Boards.

A Living Will

Dr. Jayadevan noted that, as death is a certainty for all who are living, greater awareness must be created on adults preparing a "Living Will or Advanced Directive".

A Living Will is essentially made when individuals are "still in good health— documenting one’s preference for specific treatment measures in the event of a terminal illness occurring in the future”.

“This will help relatives and doctors to take the right decisions and avoid unnecessary treatment measures in such situations. Unlike the conventional Will that is executed after death, a Living Will is implemented when a person is still alive,” the doctor said.

In a landmark judgement, the Supreme Court today allowed passive euthanasia for a 32-year-old man, living in a vegetative state for the last 13 years.

A bench comprising Justice JB Pardiwala and Justice KV Viswanathan allowed the withdrawal of life support for Harish Rana, a resident of Ghaziabad, who has been in a coma and kept alive on tubes for breathing and nutrition after sustaining severe head injuries following a fall from a building in 2013 in Chandigarh.

It is the first known case of a court-ordered passive euthanasia in India, since it was legalised in 2018 and modified in 2023, recognizing the fundamental right to die with dignity.

"Harish Rana, presently aged 32 years, was once a young, bright boy. He met with a tragic life-altering accident after a fall from the fourth floor of his paying guest accommodation. His brain injury left him in a condition of Persistent Vegetative State (PSV) with 100 percent quadraplegia... Medical reports show that his medical condition has not improved in the past 13 years," LiveLaw quoted the bench as saying.

The Court noted that the continuation of his treatment -- Clinically Administered Nutrition (CAN) via surgically installed PEG tubes -- can just prolong his biological existence but will not lead to any therapeutic improvement.

What Is The Case Of Harish Rana?

Harish was a BTech student in Chandigarh who suffered severe traumatic brain injury after falling from the fourth floor of his paying guest accommodation in August 2013.

Since then, he has remained bedridden and dependent on others for all activities of daily life.

Harish's father, the petitioner, first approached the Delhi High Court in 2024, seeking permission for passive euthanasia, but was rejected as the patient was not terminally ill.

The same year, the petitioner knocked on the doors of the Supreme Court, which, though it refused to entertain the plea, directed the Uttar Pradesh government to bear the treatment expenses.

In 2025, the petitioner filed a miscellaneous application in the Supreme Court, noting that Harish's condition had no scope for improvement.

The Court then directed the constitution of a Primary Medical Board led by the District Hospital in Noida to examine his health, as well as a Secondary Medical Board constituted by the All India Institute of Medical Sciences (AIIMS).

After perusing the report, Justice Pardiwala remarked that it's a "sad report" and the man can't continue to live like this. Before passing the final order, the Court met the parents, LiveLaw reported.

The Court has asked AIIMS to provide palliative care, so that the withdrawal of CAN can be given effect to.

To maintain the dignity of death, the apex Court said that the life support must be withdrawn with a tailored plan.

1st Passive Euthanasia: What's New From The 2018 Judgment

In 2018, a five-judge Constitution Bench had recognized and given sanction for passive euthanasia, and living will/advance directives.

Later in 2023, the SC modified the guidelines, noting that withdrawal of life support is permissible only after the approval of the Primary and Secondary Medical Boards.

With the Harish Rana judgment, the apex Court today clarified how passive euthanasia should be applied in cases where a patient’s life is being supported by feeding tubes.

The top Court waived off the reconsideration period of 30 days and noted that the medical treatment, including the CAN administered to the patient, can be withdrawn or withheld.

What is Passive Euthanasia

Passive Euthanasia allows a terminally ill or irreversibly comatose patient to die naturally. It involves deliberately withholding or withdrawing life-sustaining treatments (like ventilators, feeding tubes, or medication). It has been legal since 2018, but under strict guidelines.

In Active Euthanasia, patients are administered a lethal injection to cause death. It is illegal in India and considered an offence.

The Aruna Shanbaug case in 2011 opened the door for passive euthanasia in India for the first time.

The top Court rejected euthanasia in the case of Shanbaug, a nurse at Mumbai's KEM hospital who was in a vegetative state for 42 years after an assault in 1973, as the hospital staff who cared for her for decades did not support stopping treatment.

Shanbaug continued to be under care and passed away naturally in 2015

However, in her case, the court made the judgment allowing for passive euthanasia in certain rare situations under strict conditions.

In the wake of a shocking incident in Uttar Pradesh’s Kanpur, where two engineers allegedly died within 48 hours of undergoing hair transplant surgery by a dentist, the Indian Association of Dermatologists, Venereologists and Leprologists (IADVL) and the Association of Plastic Surgeons of India (APSI) have pressed the need for stricter rules for aesthetic and hair restoration procedures.

The doctors raised concerns about patient safety and called for ramping up training standards, even as many such cases where unqualified medical practitioners performed aesthetic procedures leading to severe infections, loss of sight, and many complications have been documented from across the country.

Traditionally, these procedures were performed by specialists such as dermatologists and plastic surgeons trained under the regulatory framework of the National Medical Commission (NMC).

However, experts said the issue has become more complicated after the Dental Council of India (DCI) allowed MDS dental surgeons, under provisions of the Dentists Act, 1948, to perform certain aesthetic procedures and hair transplantation.

“Aesthetic procedures and dermatology demand additional training. In addition to the MBBS degree, a dermatologist training program requires three years of residency at a postgraduate level in dermatology at certain accredited medical schools,” Dr Vinay Singh, President IADVL said.

He added that the training also includes a condensed curriculum of various skin ailments, hair problems, and advanced procedures in dermatology.

“Allowing professionals without comprehensive medical training in skin diseases, hair disorders, and surgical complication management to perform such procedures could dilute training standards and increase risks for patients,” warned Dr. Rajat Gupta, Senior Consultant Plastic Surgeon, Delhi.

The experts also pointed out that hair transplant is a modern medical procedure and should only be conducted by Registered Medical Practitioners (RMPs) who are specialized in that area.

Dr. Aditya Aggarwal, Senior Consultant Plastic Surgery, Medicity Medanta Hospital, shared that the surgery requires knowledge regarding the biology of the skin, the disorders of the hair, how to manage infections, and how to manage complications.

The associations urged the government to issue comprehensive guidelines and ensure strict implementation of existing regulations to curb quackery and safeguard public health.

Further, they advised the patients to verify the doctor’s qualifications and registration with the state medical council before undergoing any skin, hair, or cosmetic treatment.

The public must remain alert and avoid falling prey to misleading advertisements or treatments offered by unlicensed practitioners, the experts said.
