Dementia, a term that describes a collection of symptoms affecting memory, thinking, and social abilities, is often misunderstood.

This misunderstanding has given rise to numerous myths that not only spread misinformation but can also cause unnecessary fear and stigma.

This review aims to tackle some of the biggest myths about dementia, using evidence from recent studies to set the record straight in a language that’s easy for everyone to understand.

Myth 1: Dementia is a normal part of aging.

While it’s true that the risk of developing dementia increases with age, it’s not a normal or inevitable part of getting older. Dementia is caused by diseases that affect the brain, like Alzheimer’s disease, which is the most common form.

Research shows that while certain cognitive functions might decline slightly with age, significant memory loss or cognitive decline that interferes with daily life is not normal and is a sign of underlying disease.

Myth 2: Only older people can get dementia.

Although dementia is more common in people over the age of 65, it can also affect younger people. Early-onset dementia can occur in people in their 40s or 50s, or even younger.

This form of dementia is less common but is important to recognize as it can have a significant impact on a person’s working life and family responsibilities.

Myth 3: Dementia symptoms are all about memory loss.

Memory loss is a well-known symptom of dementia, but it’s not the only one. Dementia can affect people in various ways, depending on the area of the brain that’s damaged.

Other symptoms can include difficulties with language, problem-solving, attention, and visual perception. Some people may experience changes in their mood or behavior, such as increased irritability, depression, or apathy.

Myth 4: There’s nothing you can do to prevent dementia.

While it’s true that there’s no surefire way to prevent dementia, certain lifestyle changes can lower your risk.

Research has identified several factors that might contribute to the development of dementia, including physical inactivity, obesity, unhealthy diet, smoking, excessive alcohol consumption, and uncontrolled hypertension or diabetes.

By addressing these risk factors, individuals can potentially reduce their risk of developing dementia. Engaging in regular physical activity, eating a healthy diet, quitting smoking, and managing blood pressure and blood sugar levels are all steps in the right direction.

Myth 5: Dementia is hereditary, so if your parents had it, you will get it too.

While genetics play a role in some types of dementia, such as familial Alzheimer’s disease, these cases are relatively rare. Most people with dementia do not have a strong family history of the condition.

The presence of certain genes can increase the risk, but lifestyle and environmental factors also have a significant impact on the likelihood of developing dementia.

Myth 6: Once you have dementia, your life is over.

Dementia is a progressive condition for which there is currently no cure, but that doesn’t mean life is over after a diagnosis. Many people with dementia continue to live meaningful, fulfilling lives for many years after their diagnosis.

Early diagnosis and appropriate support can help manage the symptoms and maintain independence for longer. Support from family, friends, and healthcare professionals can also make a significant difference in managing the condition.

In conclusion, debunking myths about dementia is crucial for improving understanding and reducing stigma associated with the condition.

By addressing these misconceptions with evidence-based information, we can foster a more informed and compassionate society that supports individuals affected by dementia.

Awareness and education are key to changing perceptions and ensuring that those living with dementia receive the respect and care they deserve.
