Alzheimer’s disease as a serious and prevalent condition has only been formally identified in recent history.

However, the disease itself has existed throughout human history. Our understanding of it is relatively recent:

• Over the past 100 years: Alzheimer’s disease was first formally described in 1906 by German physician
• Over the past 50 years: The international scientific community has made major advances in understanding the disease and its impacts. Ongoing research continues in the hope of discovering treatments and a cure.
• Over the past 20 years: Thanks in part to Alzheimer Societies around the world, significant efforts have been made to reduce stigma and better support individuals living with the disease, their families, and caregivers.

Much progress has been made, but there is still much work to do.

Alzheimer’s disease is the most common neurocognitive disorder

Alzheimer’s disease accounts for 60% to 80% of all neurocognitive disorder diagnoses.

However, it is incorrect to assume that every neurocognitive disorder is Alzheimer’s disease, or that all neurocognitive disorders are forms of Alzheimer’s.

Alzheimer’s disease changes brain function

It affects a person’s way of thinking, feeling, and acting.

Each person is affected differently. While symptoms and their progression can be unpredictable, there are early warning signs to watch for.

Alzheimer’s disease is progressive. Early diagnosis increases the chances of maintaining a better quality of life. It is important to speak openly with a family doctor or consult a specialist (such as a neurologist) when significant changes in daily functioning are noticed.

• Mild stage: Memory loss, difficulty learning new things, concentration issues, and mild coordination problems may appear. Symptoms become more frequent and affect familiar tasks. Early planning and support are recommended.
• Moderate stage: Cognitive decline becomes more noticeable. Assistance is needed for daily activities, and family involvement increases significantly. Community respite services may help, and specialized care housing may be considered.
• Advanced stage: The person is no longer able to communicate verbally or care for themselves. Basic functions such as eating and hygiene are affected, requiring full-time care.
• End of life: Cognitive decline reaches a stage where full-time care is required. Palliative and comfort care are provided to ensure quality of life.

IT’S POSSIBLE TO LIVE WELL WITH ALZHEIMER’S DISEASE

Although every journey is unique and challenging, it is possible to live well with Alzheimer’s or another major neurocognitive disorder.

Research shows that healthy lifestyle habits, physical activity, and cognitive stimulation can help slow progression and support adaptation to changes.

Resources and support are available for individuals and families. Early access to support can help maintain a good quality of life for as long as possible.

Key statistics (Alzheimer’s Disease International report, Sept. 21, 2022)

• 85% of people living with a neurocognitive disorder do not receive post-diagnostic support (medical, non-medical, home support, respite, and social inclusion services).

• 62% of healthcare professionals still consider neurocognitive disorders to be a normal part of aging.

• 59% of professionals report not having enough time to provide adequate support.
