Brain Health

Brain health includes how you think, remember, focus, sleep, and manage mood. A proactive plan starts with rule-out labs that can explain memory or thinking changes, then adds brain-specific biomarkers when concern remains. Begin with thyroid (TSH), vitamin B12, metabolic and blood counts, A1c, and lipids to uncover common, fixable causes or risks. If problems persist, clinicians may order Alzheimer’s blood biomarkers—the amyloid beta ratio (Aβ42/40) and phosphorylated tau (p-tau)—often paired with neurofilament light (NfL) to gauge nerve-cell injury. Results guide next steps, which can include cerebrospinal ... See more

What Is a Decline in Brain Health?

There is no universally recognized definition for brain health, but researchers know that a decline in brain health is marked by changes that negatively impact your quality of life.

Since the brain works throughout the entire body, signals of decline in brain health can manifest in many different ways. However, a patient with brain decline will ... See more

Have you ever forgotten someone’s name or where you placed your car keys? Have you ever joked that you have a senior moment during those times? Well, the truth is that; it is common for everyone to experience mild memory loss. However, cognitive decline is not a laughing matter.

As a matter of fact, for many of us, experiencing a declining brain function is the most feared side effect of aging. Studies show that an estimated one out of three seniors die with dementia and Alzheimer’s diseases. However, this does not mean that it is an aging process factor.

Although aging is defiantly a risk factor, scientists believe that dementia, Alzheimer’s, and other memory-related diseases are caused by environmental factors, lifestyle choices, and genetics. With that in mind, it makes things easier to know the steps you need to take to reduce the risk factors and help maintain a healthy brain even as one ages.

Therefore, the million-dollar question is; what are the five ... See more
