Do you find yourself pausing mid-sentence, searching for a word that used to come instantly? Or you’ve reread the same paragraph three times before it finally sinks in. Many adults notice these moments and wonder if serious memory loss lies ahead. Fortunately, research paints a more hopeful picture. According to the 2024 Lancet Commission on Dementia Prevention, Intervention, and Care, addressing the known modifiable risk factors for cognitive decline could potentially prevent up to 45 percent of dementia cases worldwide.¹ That means nearly half of future cognitive decline may be within your influence, not outside of it.
At Hotze Health & Wellness Center, we believe education is the first step toward taking control of your health. Below, we walk through nine modifiable risk factors for cognitive decline, the research behind each one, and how an integrative, root-cause approach addresses them.
A modifiable risk factor is a condition or behavior you can change, unlike your age, sex, or genetic makeup. Researchers distinguish these factors because they represent real opportunities for prevention. Instead of viewing cognitive decline as inevitable, current science treats it as the cumulative result of choices, exposures, and untreated conditions that build over decades.
The nine modifiable risk factors for cognitive decline we cover in this article include:
Each factor on this list interacts with the others. For example, physical inactivity often worsens obesity, which then raises blood pressure and blood sugar. Consequently, addressing one factor often improves several at once.
High blood pressure damages the delicate blood vessels that supply the brain with oxygen and nutrients. Over time, this damage restricts blood flow and contributes to both vascular dementia and Alzheimer’s disease. The landmark SPRINT MIND trial followed more than 9,300 adults aged 50 and older with hypertension and found that intensive blood pressure control significantly reduced the combined rate of mild cognitive impairment and probable dementia.² Notably, researchers observed that this protective effect persisted for years after the intensive treatment period ended.
Because hypertension often develops silently, regular monitoring matters well before symptoms appear. At Hotze Health & Wellness Center, we look beyond blood pressure to understand the bigger picture of cardiovascular health. Our approach considers the body as a whole, including how well it responds to and manages stress and other factors that may influence not just cardiovascular health but also other health factors such as brain health.
Hearing loss ranks among the most significant modifiable risk factors for cognitive decline identified in dementia research. A meta-analysis of prospective cohort studies involving more than 726,000 participants found that hearing loss was independently associated with a substantially elevated risk of dementia, even after researchers adjusted for other health factors.³ Untreated hearing loss may accelerate cognitive decline through several pathways, including reduced auditory stimulation to the brain, increased cognitive load during listening, and greater social withdrawal.
Many people delay addressing hearing loss because the change happens gradually. However, early evaluation and correction may help preserve both communication and cognitive engagement over time.
Diabetes affects far more than blood sugar. Chronic high glucose levels damage blood vessels throughout the body, including those in the brain, and contribute to inflammation and insulin resistance in brain tissue. A large cohort study found that individuals diagnosed with type 2 diabetes before age 50 faced more than three times the risk of all-cause dementia compared to those without diabetes, with elevated risk persisting even when diagnosis occurred later in life.⁴
This research reinforces why early, consistent blood sugar management matters so much. Furthermore, the link between diabetes and cognitive decline underscores how metabolic and brain health are deeply intertwined.
For those who want ongoing insight into their blood sugar patterns, we carry the Stelo Glucose Biosensor (not for people on insulin), a wearable sensor that tracks glucose trends throughout the day. This kind of real-time data can help guests and our clinical team identify patterns related to diet, activity, and stress well before a diabetes diagnosis occurs.
Movement benefits the brain in ways that extend well beyond cardiovascular fitness. A systematic review and meta-analysis pooling data from more than 257,000 participants found that higher physical activity was associated with a 20 percent reduction in all-cause dementia risk and similarly reduced rates of Alzheimer’s disease and vascular dementia.⁵ Exercise appears to work through several mechanisms, including improved blood flow, reduced inflammation, and support for the brain’s natural repair processes.
The encouraging news is that physical activity remains one of the most accessible tools for lowering cognitive decline risk factors at any age. Even moderate, consistent activity, such as brisk walking, offers measurable benefit.
The remaining risk factors on the Lancet Commission’s list each carry independent weight, and together they round out the full picture of modifiable risk factors for cognitive decline. The table below summarizes how each one contributes to risk.
| Risk Factor | How it Affects the Brain | Ways to Address It |
| Obesity | Drives chronic inflammation and worsens insulin resistance, both linked to cognitive decline | Sustainable nutrition changes, regular movement, and evaluation for underlying metabolic or hormonal contributors |
| Depression | Associated with changes in brain structure and function that may compound over time | Mental health support, consistent physical activity, and evaluation for hormone imbalances that can mimic or worsen mood changes |
| Social Isolation | Reduces cognitive stimulation and is linked to a measurably higher risk of dementia¹ | Regular engagement with family and friends, community or faith groups, and structured activities that combine movement with connection |
| Untreated Vision Loss | Limits environmental engagement and was newly added as a risk factor in the 2024 report¹ | Annual eye exams and timely correction through glasses, updated prescriptions, or referral for further evaluation |
Since these factors often cluster together in the same individual, an integrative evaluation that considers the whole person, rather than a single symptom, provides a clearer path forward.
Beyond the eight factors above, hormone balance deserves serious attention when discussing modifiable risk factors for cognitive decline. Thyroid hormones support brain metabolism, myelination, and memory-related brain regions.⁶ Estrogen, progesterone, and testosterone also play protective roles in neuron health and cognitive clarity.
When these hormone levels decline, your body is not lacking pharmaceutical drugs. Rather, your body naturally depletes necessary hormones over time. When that happens, the answer is to replenish them with bioidentical hormone therapy. We do not utilize synthetic forms of hormones; they can cause too many unwanted and, in some cases, severe side effects. At Hotze Health & Wellness Center, we evaluate clinical symptoms alongside comprehensive bloodwork, since normal lab ranges do not always match how a person actually feels. This integrative approach allows our medical team to identify imbalances that standard screenings often overlook.
At Hotze Health & Wellness Center, we treat the whole body, not just an isolated symptom. This way, we get to the root cause of symptoms while also supporting prevention and healthspan. As a population, we are living longer, and those additional years should be quality years, filled with clarity, energy, and connection rather than decline.
This philosophy shapes how we approach every guest’s care plan. Rather than addressing a single lab value or symptom, our team looks across hormone balance, metabolic health, nutrition, and lifestyle factors together. Since so many modifiable risk factors for cognitive decline interact with one another, this comprehensive view often uncovers connections that a narrower approach would miss.
Since so many modifiable risk factors for cognitive decline overlap with hormone balance, metabolic health, and cellular aging, Hotze Health & Wellness Center offers a dedicated Brain Support Program for guests who want a proactive, structured plan. This program begins with a detailed medical and lifestyle evaluation, followed by comprehensive bloodwork and advanced testing tailored to your individual needs.
From there, our team builds a personalized strategy that may include targeted nutrition, vitamin and mineral supplementation, and additional integrative therapies designed to support brain health alongside overall vitality.
Two therapies in this program are Sirolimus (also known as Rapamycin) and Methylene Blue. Sirolimus is widely studied for its role in supporting healthy cellular aging pathways, and many guests report benefits such as increased energy, sharper mental clarity, and improved mood. Methylene Blue supports mitochondrial function and cellular energy production, which may help address the underlying cellular stress associated with cognitive changes. Both therapies are considered as part of a broader, personalized plan rather than as standalone solutions. There are many more tools and lifestyle modifications that we utilize in partnership with our guests. Our providers are Recode Certified in the prevention and treatment of Cognitive Decline and Cognitive Decline concerns.
Whether you are focused purely on prevention or already noticing changes, this program meets you wherever you are on your journey toward a longer, healthier healthspan.
For over 35 years, Hotze Health & Wellness Center has helped guests uncover the root causes behind fatigue, brain fog, and other frustrating symptoms. We are often people’s last stop after they have already seen multiple doctors without answers. Why does this happen so often? Because we listen. Our team combines your clinical symptoms with thorough laboratory testing to build a complete picture of your health, rather than relying on standard bloodwork results alone.
This approach has served more than 33,000 guests since 1989, reflecting our core belief that lasting wellness starts with understanding, not guesswork.
