Understanding the onset of dementia is crucial for patients, caregivers, and health professionals. It raises awareness and facilitates timely intervention. Dementia is often misunderstood as a normal part of aging. Yet, this condition has profound impacts, affecting cognition, behavior, and the ability to perform everyday tasks. 

If you are older than 65, you have a greater chance of developing dementia. However, people with dementia earlier than 65 years old are dubbed with early-onset dementia. While other factors like brain injury, overall health, and well-being can play a significant role in developing dementia. So, let’s dive into this condition that significantly impacts lives across the globe.

Understanding Dementia

Dementia is not a disease itself but rather a syndrome – a group of symptoms affecting memory, cognition, and social abilities. Common forms include Alzheimer’s disease, vascular dementia, Lewy body dementia, and frontotemporal dementia.

Age-Related Risk Factors

As we age, our risk of developing dementia increases. This is due to several factors, such as declining neural health, genetics, heart health, and lifestyle. However, age alone is not a determinant of dementia.

Early-Onset Dementia

Early onset dementia refers to dementia occurring before 65 years of age. While relatively rare, it’s impactful, often striking individuals in their prime working years. Causes are multifaceted, including genetic predisposition, environmental factors, and lifestyle.

Late-Onset Dementia

Late-Onset Dementia occurs after the age of 65 and is the most common form. The causes range from cerebrovascular disease to Alzheimer ‘s-related changes. Understanding these causes is crucial for both prevention and treatment.

People in the late stage of Alzheimer’s disease can’t carry on conversations, lose awareness of what’s going on around them, and can’t control their movement.

Difficulties may include:

  • Trouble communicating
  • Difficulty with walking
  • Trouble swallowing food and medications
  • More prone to infections, especially pneumonia
  • Requiring 24-hour assistance with care

Risk Reduction & Prevention

A healthy lifestyle can lower the risk of dementia. This includes regular exercise, a balanced diet, cognitive training, and meaningful social engagement. Managing other health conditions like diabetes or hypertension also plays a role. 

Risk Factors for Dementia

Age: This is the most decisive risk factor. Your chance of dementia increases as you age. Most cases affect people over the age of 65.

Family history: If you have biological parents or siblings with dementia, you’re more likely to develop dementia.

Down syndrome: If you have Down syndrome, you’re at risk of developing early-onset Alzheimer’s disease by middle age.

Poor heart health: If you have high cholesterol levels, high blood pressure, atherosclerosis, or smoke, you increase your risk of dementia. These health problems, as well as diabetes, affect your blood vessels. Damaged blood vessels can lead to reduced blood flow and strokes.

Race and ethnicity: Compared to caucasians, African Americans have twice the risk of developing dementia, and Hispanics are 1.5 times more likely.

Brain injury: If you’ve had a severe brain injury, you’re at a higher risk for dementia.

Tips on Caring for a Dementia Patient

  • Establish Daily Routines: This helps reduce confusion and anxiety for dementia patients. 
  • Promote Physical Exercise: Regular physical activity can improve mood and maintain the health of the heart, muscles, and joints.  
  • Encourage Social Interaction: Keep the patient engaged with family and community to uphold their sense of belonging and self. 
  • Create a Safe Living Space: A dementia-friendly home reduces the risks of injuries and accidents.
