Understanding Alzheimer’s: A silent thief of memories

By Evelina Petkeviciute, a Castlebar transition year student

Alzheimer’s is the most common cause of dementia, affecting millions of people and their families around the world.

In Ireland approximately 64,000 people are living with dementia.

Alzheimer’s disease begins with a biological process involving a build-up of proteins in the brain.

These proteins form amyloid plaques (abnormal deposits) and neurofibrillary tangles, which disrupt brain function. Over time, this causes brain cells to die and the brain to shrink.

Among more than 200 types of dementia, Alzheimer's is the most common.

The disease can begin developing 15 to 20 years before any symptoms appear. Signs typically start to show up later in life, usually after age 65.

Early symptoms include forgetting recent conversations or events, mood or personality changes, impaired judgement, and behavioural shifts.

As the disease progresses, it leads to severe memory loss and a decline in ability to perform everyday tasks.

September is recognized as World Alzheimer’s Month, an international campaign to raise awareness and challenge the stigma surrounding Alzheimer's and other forms of dementia.

It focuses on helping the public understand dementia, recognise the early signs, and support those living with it.

The campaign also advocates for better care services, stronger support systems, and increased research funding.

To mark the month, individuals and communities are encouraged to wear purple which is the official colour of Alzheimer's awareness.

Many also take part in activities such as educational workshops, memory cafes, fundraising events, and memory walks. These efforts help raise awareness, fund research, and provide support to those affected.

Although there is currently no cure for Alzheimer's disease, raising awareness and promoting education can help with early diagnosis, slowing the progression of symptoms, and maintaining brain health.

In advanced stages, the disease can lead to complications such as dehydration, poor nutrition, and infections, which can ultimately result in death.

Alzheimer doesn't just affect the individual, it ripples through families, communities, and the wider healthcare system. Raising awareness is a critical step in supporting those living with the disease and pushing for better treatments, and one day, a cure.

Everyone can help make a difference, whether it's by taking part in awareness campaigns, supporting caregivers, volunteering, donating, or simply learning more and sharing that knowledge with others.
