10 Important Facts About Alzheimer's and Vascular Dementia


Alzheimer’s disease and Vascular Dementia (VaD) account for a substantial majority of dementia cases across the globe. Understanding these conditions, their differences, similarities, and potential treatment strategies are crucial in today’s society, where dementia incidence is on the rise. With the global population aging, both Alzheimer’s and VaD are projected to impact an increasing number of individuals and families.


In this discussion, we will explore ten key aspects of these diseases, shedding light on their inner workings, impacts, and available therapeutic interventions.

Before delving into the complexities, let’s start with the basics. Alzheimer’s disease and Vascular Dementia are two prevalent forms of dementia. While they share similarities in their manifestation, primarily cognitive decline, they have distinct causes and progression patterns.

Alzheimer’s disease is the most common type of dementia. It is characterized by the presence of plaques and tangles in the brain, leading to a progressive decline in memory and other cognitive abilities. Vascular Dementia, the second most common form, is typically caused by conditions that block or reduce blood flow to the brain, depriving brain cells of vital nutrients and oxygen. This lack of blood flow can cause a series of small strokes leading to cognitive decline.

Dementia, including Alzheimer’s and VaD, is a significant global health issue. According to the World Health Organization, around 50 million people worldwide have dementia, with nearly 10 million new cases each year. Alzheimer’s accounts for between 60 to 70 percent of these cases, while VaD contributes to a substantial portion of the remaining cases.

The impact of these conditions extends beyond the affected individuals, significantly influencing caregivers’ lives, healthcare systems, and society at large. The burden of dementia, both emotional and economic, is enormous, with global costs estimated to be over $1 trillion annually.

Fact 1: Unraveling Alzheimer’s – More Than Just Memory Loss

Alzheimer’s disease is notoriously associated with memory loss. Yet, this formidable disease impacts more than just an individual’s ability to recall past events or familiar names. It’s a progressive neurodegenerative condition, gradually chipping away at various cognitive and behavioral abilities. Over time, individuals with Alzheimer’s may find it increasingly challenging to carry out basic, everyday tasks.

The process begins subtly, often mistaken for common age-related forgetfulness. A misplaced item here, a forgotten appointment there. It’s easy to dismiss these early warning signs as minor hiccups. However, as the disease advances, the effects become more apparent. Someone with Alzheimer’s might find it hard to hold a conversation, losing their train of thought mid-sentence or struggling to find the right words. This cognitive decline extends to problem-solving abilities and critical thinking, impacting decision-making processes.

There’s also a significant shift in mood and personality. As brain function deteriorates, individuals with Alzheimer’s might display unpredictable behavior and emotional outbursts. They may become confused, anxious, or suspicious, particularly in unfamiliar environments. These personality changes can be distressing for both the individual and their loved ones, presenting additional challenges to an already trying situation.

Over 50 million people across the globe are currently living with Alzheimer’s, demonstrating its immense global significance. Despite extensive research efforts, a cure for Alzheimer’s remains elusive, adding urgency to the quest for improved understanding and effective treatment options. (1)
