Alzheimer’s and Brain Awareness Month

Every June, the world goes purple for Alzheimer’s and Brain Awareness Month. Not just to remember those living with the disease – but to remind every one of us that the brain we take for granted today needs our attention right now, long before any symptom appears. 

Why June, and Why Does It Matter So Much?

Alzheimer’s and Brain Awareness Month was established by the Alzheimer’s Association to dedicate an entire month to what has become one of the most quietly devastating health crises of our time. Worldwide, over 55 million people are currently living with dementia – and Alzheimer’s disease accounts for 60 to 70 percent of those cases. In India, estimates suggest over 8.8 million people are living with dementia, a number projected to more than double by 2050.

What makes these numbers especially sobering is this: for every person diagnosed, there are typically three to five family members whose lives are transformed alongside them – quietly, gradually, and without much public acknowledgment. Alzheimer’s is rarely just one person’s illness. It is a family’s journey.

What Alzheimer’s Disease Actually Is?

Most people think of Alzheimer’s as “forgetting things.” That is where it begins, but it is far from where it ends. Alzheimer’s is a progressive neurological disease – meaning it advances steadily over time – in which abnormal protein deposits called amyloid plaques and tau tangles build up in the brain, disrupting communication between brain cells and eventually causing them to die.

The brain shrinks. Connections are lost. And with them, memories, language, reasoning, personality, and eventually the ability to perform the most basic daily functions disappear – one by one, over years.

What is particularly cruel about Alzheimer’s is that it begins damaging the brain silently, up to 20 years before the first symptom appears. By the time a person forgets a name or loses their way on a familiar street, the disease has already been quietly at work for a long time.

Alzheimer’s vs. Normal Ageing

This is the question families wrestle with most. Is this normal ageing, or is something wrong?

Forgetting where you placed your keys and then remembering later – that is normal ageing. Forgetting that keys exist, or what they are used for – that is not. Taking longer to recall a name but getting there eventually – normal. Asking the same question five times in one conversation with no awareness of having asked before – not normal.

Normal ageing slows the brain slightly. Alzheimer’s erases. The difference between occasional forgetfulness and a consistent, progressive pattern of confusion, disorientation, and personality change is the signal that deserves a neurologist’s attention – and the earlier that attention comes, the more that can be done.

The Warning Signs Families Often Miss For Years

Alzheimer’s is a master of disguise in its early stages, and families often look back and recognize signs they had explained away for years. The ten early warning signs identified by neurologists and dementia specialists worldwide include memory loss that disrupts daily life – particularly forgetting recently learned information; difficulty planning or solving problems that were once routine; confusion with time, dates, and the passage of seasons; trouble understanding visual images and spatial relationships, which sometimes first shows up as difficulty driving; new problems with words – losing track mid-sentence, calling familiar objects by wrong names, or withdrawing from conversations altogether; misplacing things and being unable to retrace steps to find them; increasingly poor judgement, particularly around money or personal hygiene; withdrawal from social activities and hobbies once loved; and noticeable changes in mood, personality, or behaviour – new anxiety, suspicion, depression, or uncharacteristic emotional reactions.

None of these alone confirms Alzheimer’s. But a pattern of several, persisting over months and worsening over time, is reason to seek evaluation – not next month, not after one more family discussion, but now.

Who Is at Risk – And What Actually Increases That Risk?

Age is the single greatest risk factor. The likelihood of developing Alzheimer’s roughly doubles every five years after the age of 65. But here is what most people do not know – nearly 5 to 10 percent of Alzheimer’s cases are early-onset, meaning they develop before the age of 65, sometimes as early as the forties. Alzheimer’s is not purely an old person’s disease.

Genetics play a role, particularly a gene variant called APOE-e4. Having one copy raises risk; having two copies raises it significantly. However, carrying the gene does not guarantee the disease, and many people without it still develop Alzheimer’s – which is why genetics is a factor, not a sentence.

Other risk factors that research has firmly established include uncontrolled high blood pressure and diabetes, chronic poor sleep, long-term social isolation, untreated depression, significant hearing loss left unaddressed, physical inactivity through midlife, smoking, obesity, and low levels of cognitive engagement over a lifetime. What is remarkable – and hopeful – about this list is how many of these factors are within our control.

What Happens in the Brain – Without the Medical Jargon

Imagine your brain as an incredibly complex city, with billions of roads connecting billions of buildings. In Alzheimer’s, those roads begin to get blocked – first in the areas governing memory and language, then spreading outward. Messages stop reaching their destinations. Buildings – brain cells – that receive no traffic begin to shut down. Eventually, entire districts of the city go dark.

The hippocampus – the brain’s memory headquarters – is typically affected first, which is why memory loss is the earliest and most recognizable symptom. As the disease progresses, it moves into regions responsible for reasoning, language, and eventually movement and basic bodily function. This is why advanced Alzheimer’s affects not just the mind but the body’s ability to walk, swallow, and regulate itself.

Can Alzheimer’s Be Prevented? What Science Actually Says

There is no guaranteed prevention, and anyone claiming otherwise is overstepping the science. But the research is genuinely encouraging about what reduces risk. A landmark global study – the FINGER trial – demonstrated that a combination of physical exercise, mental stimulation, social engagement, a heart-healthy diet, and management of vascular risk factors meaningfully slowed cognitive decline in at-risk adults. Not cured it, but slowed it – which in the context of Alzheimer’s is significant.

What this tells us is that the brain responds to how we live. Thirty minutes of aerobic exercise most days, learning something new consistently, staying connected to people, sleeping seven to eight hours, managing blood pressure and blood sugar – these are not miracle cures. They are evidence-based investments in long-term brain health that every person can begin making today, regardless of age.

Diagnosis and Treatment – Honest Answers

Alzheimer’s is diagnosed through a combination of detailed cognitive assessments, neurological examination, blood tests, and brain imaging – typically MRI and increasingly PET scans that can detect amyloid deposits in the brain. A formal diagnosis opens the door to treatment, planning, and support that dramatically improves quality of life for both the patient and the family.

Current medications – cholinesterase inhibitors and memantine – do not reverse or halt the disease, but they manage symptoms and slow progression meaningfully in many patients. More significantly, newer drug therapies targeting amyloid plaques have recently received approval and represent the most important shift in Alzheimer’s treatment in decades, with ongoing trials continuing to refine their use.

Beyond medication, structured daily routine, cognitive stimulation therapy, physical activity, and strong psychosocial support – for the patient and the caregiver – are central to comprehensive Alzheimer’s care.

The Person Behind the Diagnosis

Something that clinical language often fails to honour – every person living with Alzheimer’s is still a full human being with a history, preferences, dignity, and moments of absolute clarity and joy. The disease changes a person; it does not erase who they are. How families and caregivers respond – with patience, presence, and understanding – shapes the lived experience of Alzheimer’s as profoundly as any medication.

Caregiver burnout is real, widespread, and dangerously underacknowledged. If you are caring for someone with Alzheimer’s, seeking support for yourself is not a weakness. It is what makes sustained, compassionate care possible.

Frequently Asked Questions 

Q: What is Alzheimer’s and Brain Awareness Month?

Every June is observed as Alzheimer’s and Brain Awareness Month, established by the Alzheimer’s Association to raise global awareness about Alzheimer’s disease and dementia. The month encourages early detection, supports patients and caregivers, and drives conversations about long-term brain health before symptoms ever appear.

Q: What is the difference between Alzheimer’s disease and dementia?

Dementia is an umbrella term for a group of symptoms affecting memory, thinking, and daily function. Alzheimer’s disease is the most common cause of dementia, accounting for 60 to 70 % of all dementia cases. Not all dementia is Alzheimer’s, but all Alzheimer’s is a form of dementia.

Q: What are the early warning signs of Alzheimer’s?

The most recognised early signs include memory loss that disrupts daily life, difficulty with planning or problem-solving, confusion about time and dates, new trouble with words or conversations, misplacing objects without being able to retrace steps, poor judgement, withdrawal from social activities, and noticeable changes in mood or personality. A pattern of several of these signs, worsening over months, warrants neurological evaluation without delay.

Q: At what age does Alzheimer’s typically develop?

While age is the greatest risk factor and risk roughly doubles every five years after 65, Alzheimer’s is not exclusively a disease of old age. Between 5 and 10 percent of cases are early-onset, developing before the age of 65 — sometimes as early as the forties. Alzheimer’s can affect working-age adults and should not be dismissed on grounds of age alone.

Q: What causes Alzheimer’s disease?

Alzheimer’s is caused by the abnormal buildup of proteins — amyloid plaques and tau tangles — in the brain that disrupt communication between brain cells and eventually cause them to die. The exact trigger varies. Known risk factors include age, genetics particularly the APOE-e4 gene variant, uncontrolled blood pressure and diabetes, chronic poor sleep, social isolation, physical inactivity, smoking, obesity, and untreated depression.

Q: Can Alzheimer’s disease be prevented?

There is no guaranteed prevention. However, research — including the landmark FINGER trial — has shown that a combination of regular physical exercise, mental stimulation, social engagement, a heart-healthy diet, and management of vascular risk factors can meaningfully slow cognitive decline in at-risk individuals. Many of the known risk factors for Alzheimer’s are within our control, making lifestyle choices a genuinely important part of long-term brain health.

Q: How is Alzheimer’s diagnosed?

Alzheimer’s is diagnosed through a combination of detailed cognitive assessments, neurological examination, blood tests, and brain imaging — typically MRI and increasingly PET scans capable of detecting amyloid deposits in the brain. Early diagnosis is important because it opens the door to treatment, planning, and support that significantly improves quality of life for both the patient and their family.

Q: What support is available for Alzheimer’s caregivers?

Caregiver burnout is a serious and widely underacknowledged issue. Caregivers need and deserve support — through counselling, respite care, support groups, and medical guidance on managing the evolving needs of the person they care for. Seeking help as a caregiver is not a sign of weakness. It is what makes sustained, compassionate long-term care possible.
