As we age, our bodies go through various changes, not all of which are visible. One of the
most devastating impacts of aging is the development of neurodegenerative diseases like
dementia. This series of blog posts aims to shed light on the topic of dementia, focusing on two main types: Alzheimer's disease and vascular dementia. We will also discuss the importance of prevention and early intervention in managing this condition, especially in countries like South Africa where the population is relatively young.
About Dementia
The term 'dementia' is used to describe a group of symptoms that impact memory,
performance of daily activities, and communication abilities. Alzheimer's disease and
vascular dementia are the two most common forms of this disease, however neurodegenerative diseases also include Parkinson's disease and Lewy body dementia. These conditions can severely impact a person's life, making it essential to discuss and understand.
In South Africa, where the population is not very old, dementia hasn't been a significant
focus, unlike other diseases such as diabetes and cardiovascular disease. However, as the population ages, the prevalence of dementia is expected to increase. Currently, only about 1% of deaths in South Africa are related to dementia diseases like Alzheimer's. However, for those who have experienced a loved one suffering from dementia, the statistics become irrelevant as the disease takes a personal and emotional toll.
Preventing Dementia
There's been a global shift in thinking about dementia and related diseases. The focus is now on prevention and the delaying of the disease, rather than just treating it after diagnosis. The
disease often starts 10-20 years before diagnosis, meaning that actions taken in your 40s and 50s can significantly impact your risk of developing dementia in later life. Research conducted in countries with older populations, like the UK and US, has shown that
it's possible to lower your chances of developing dementia by around 40% through lifestyle
changes and taking certain supplements. By starting early, you can significantly reduce the
risk of dementia and maintain your mental health into old age.
While dementia may not currently be a top concern in countries with younger populations,
it's essential to start taking steps towards prevention as early as possible. By focusing on
maintaining a healthy lifestyle, taking recommended supplements, and staying informed
about the disease, we can hope to reduce the risk of dementia and ensure a healthier, happier old age. The battle against dementia is not just for the individual but also for the families and caregivers who support them. By spreading awareness and understanding, we can all play a part in this important fight.

A Deep Dive into Alzheimer's Disease
Alzheimer's disease, a form of dementia, is a condition that has been widely misunderstood and misdiagnosed. Named after Dr. Alzheimer, who identified the first patient, it's a condition
that's often associated with memory loss. However, it's crucial to understand that
Alzheimer's is more than just a memory disorder; it affects the whole body and the entire
person. The disease was initially identified in an asylum, where patients were often locked away. Dr. Alzheimer performed an autopsy on a patient who showed significant changes in the brain; interestingly, the patient died of a cold rather than Alzheimer's itself, but the disease was named after Dr. Alzheimer by his successors.
There are many diseases that resemble Alzheimer's, especially in their early stages. The
hallmark of Alzheimer's disease is the presence of amyloid plaques in the brain, however, the
symptoms can vary widely. In addition to memory loss, patients may experience balance and
speech symptoms, muscular symptoms, and even autonomic symptoms affecting the bowels.
Another form of dementia is vascular dementia, which often overlaps with Alzheimer's.
Vascular dementia can result from small strokes that accumulate over time, causing cognitive
decline. Physicians often categorize Alzheimer's and vascular dementia separately, but in
reality, many patients exhibit symptoms of both conditions.
Diagnosing dementia often begins with a family member or caregiver noticing memory loss or cognitive decline. Medical professionals use questionnaire-based screening tools to assess the patient's condition but the diagnosis is primarily clinical; it's often challenging to
distinguish between different forms of dementia.
There are other types of dementia, such as Parkinson's disease and Lewy body dementia, but these are less common. Parkinson's disease is more of a movement disorder, while Lewy body dementia combines memory and movement disorders with potential visual hallucinations.
While there are many medications available for treating dementia, their efficacy is often
limited. They may slow the progression of the disease but are not a cure. In contrast, lifestyle
interventions can potentially delay or even prevent the onset of dementia, making
preventative measures a key aspect of dementia care.
Everyone will experience some level of cognitive decline with age. However, with the right
interventions, it's possible to delay this decline significantly. The goal should be to start with a "full tank," so to speak; keeping our cognitive reserves as high as possible to withstand the
inevitable cognitive decline that comes with aging.
Understanding these conditions, their symptoms, and their progression is vital for patients,
caregivers, and medical professionals alike. The more we know about Alzheimer's and other
forms of dementia, the better equipped we are to combat them. In the end, it's not just about
extending lifespan, it's about enhancing the quality of life for those living with these
conditions and their loved ones.
In our next blog post (Part 2), we discuss supplements and the promising results they are showing in delaying the onset of dementia.
