Dementia is a growing concern in the United States, over the age of 55? Take a look here!

At the Center for Neurology and Spine, we are committed to raising awareness about dementia, a condition projected to affect millions of Americans in the coming decades. Recent studies highlight that dementia cases in the U.S. could rise to nearly 1 million annually by 2060, making it more important than ever to understand this condition and take proactive steps to reduce risk.

The new study (Lifetime risk and projected burden of dementia | Nature Medicine) relies on information gathered from the ongoing Atherosclerosis Risk in Communities Neurocognitive Study (ARIC-NCS), which, since 1987, has closely tracked the vascular health and cognitive function of nearly 16,000 participants as they age. ARIC-NCS is also, the researchers say, the longest-followed cohort of African-Americans for cognition and heart health.

Publishing in the journal Nature Medicine online Jan. 13, the study concludes that from 1987 until 2020, there were 3,252 study participants who were documented as having developed dementia.

This translates to an overall lifetime risk for dementia among middle-aged Americans of 42%, which is an average of the 35% risk in men and the 48% risk in women. The excess risk in women was largely due to their lower death rates.

The new results also showed a higher risk among Black adults and in those who carried a variant of the APOE4 gene (between 45% and 60%), which codes for a protein that carries cholesterol and other lipids in the bloodstream.

Having a certain version of APOE4 is thought to be the single biggest genetic risk factor in developing late-onset Alzheimer’s disease.

The Growing Dementia Crisis

According to the study, dementia cases are expected to rise dramatically due to an aging population. The research emphasizes the importance of public health strategies to prepare for this surge and improve quality of life for those affected.

What is Dementia?

Dementia is a group of cognitive disorders that impact memory, thinking, and the ability to perform daily tasks. Alzheimer’s disease is the most common form, but other types include:

• Vascular Dementia: Linked to poor blood flow to the brain.
• Lewy Body Dementia: Characterized by abnormal protein deposits in the brain.
• Frontotemporal Dementia: Affects personality and behavior due to changes in the brain’s frontal and temporal lobes.

Current Treatments for Dementia

While there is no cure, medications and therapies aim to slow progression and manage symptoms:

1. Cholinesterase Inhibitors: Drugs like Donepezil and Rivastigmine enhance communication between brain cells.
2. Memantine (Namenda): Protects brain cells from overactive glutamate, used for moderate to severe dementia.
3. Anti-Amyloid Drugs:
   • Lecanemab (Leqembi) and Donanemab are recent breakthroughs that target amyloid plaques in the brain.

New Treatments in Development

Ongoing clinical trials are exploring innovative ways to combat dementia:

• Anti-Tau Therapies: Target the tangles of tau proteins found in Alzheimer’s disease.
• Gene Therapy: Investigating ways to address genetic risk factors like APOE4.
• Neuroinflammation Modulators: Reducing brain inflammation to protect neurons.

Proactive Steps to Reduce Dementia Risk

While some risk factors like age and genetics are unavoidable, you can take steps to lower your risk:

1. Stay Active: Engage in regular physical exercise to improve blood flow and brain health.
2. Eat a Brain-Healthy Diet: Focus on fruits, vegetables, whole grains, and lean proteins. The Mediterranean diet is highly recommended.
3. Stimulate Your Mind: Challenge your brain with puzzles, reading, or learning a new skill.
4. Stay Socially Engaged: Regular interactions with friends and family help maintain mental well-being.
5. Manage Chronic Conditions: Control blood pressure, diabetes, and cholesterol.
6. Get Quality Sleep: Aim for 7–8 hours of restful sleep each night.
7. Protect Your Brain: Wear helmets during high-risk activities to avoid traumatic brain injuries.
8. Limit Alcohol and Avoid Smoking: Both are linked to an increased risk of dementia.

Why Arizona Matters

Arizona is uniquely positioned to support advancements in dementia research, with a growing population of older adults and access to cutting-edge clinical trials. By participating in research and adopting preventive measures, residents can contribute to groundbreaking discoveries and live healthier lives.
