Cognitive / Brain Health
Your body's quiet command system, and how to keep it working for you.
Proactive care to protect your memory, sharpness, and long-term independence.
Clear thinking doesn't fade overnight. Changes in focus, word-finding, and mental energy build gradually over decades, often starting long before any noticeable symptoms arrive. At Advanced Medicine and Wellness, Dr. Prathibha Potharlanka looks at brain health as a dynamic system to measure, protect, and optimize early—helping you stay sharp and self-reliant for the years ahead.
1. Is This Path for You?
Who this page is for
This page is not only for people who are worried about dementia.
It's for the proactive adult, typically 55 and older, who wants to stay sharp and independent, and who has noticed that the mind doesn't always feel as quick as it used to. You may recognize yourself here:
-
You walk into a room and forget why, or lose words and names more often than before.
-
It's harder to concentrate, follow a long conversation or keep track of several things at once.
-
You feel mentally tired or foggy, especially in the afternoon or after a poor night's sleep.
-
A parent or grandparent had memory loss, and you wonder about your own risk.
-
Friends or family have commented that you repeat yourself or seem more distracted.
-
Your last physical came back "normal," and no one asked about your memory at all.
It's also for people who feel perfectly sharp and want to keep it that way. Many of the things that protect the brain are the same things that protect the heart, and they work best when started early.
If you'd rather protect your memory than simply hope for the best, this path was built for you.
Reactive Care: Wait for memory problems → Seek a diagnosis
Proactive Care: Know your risks → Protect the brain → Stay sharp longer
Core takeaway: Forgetfulness isn't always "just aging." It deserves a real look, and many causes can be helped.
2. What Your Routine Checkup Isn't Telling You
What we're actually looking at
A routine annual visit rarely includes a real look at brain health. Memory may come up only if you mention it, and a quick question or two can't tell you much.
Here's the difference in plain terms.
A routine checkup looks for disease in the body. It usually doesn't ask how well you're thinking, sleeping, hearing or coping, even though all of these shape how the brain ages.
A comprehensive brain health evaluation looks at the whole picture. Many things that affect memory and focus are common and treatable, and they're easy to miss unless someone looks for them. Depending on your history, Dr. Potharlanka may evaluate:
-
Memory and thinking: a brief, structured check of memory, attention and problem-solving, which also creates a baseline for the future.
-
Heart and blood vessel health: blood pressure, cholesterol and blood sugar, because what is good for the heart is good for the brain.
-
Common, treatable causes of brain fog: such as thyroid problems, low vitamin B12 and other nutrient gaps that can affect memory and energy.
-
Sleep: how well you really sleep, including signs of problems such as sleep apnea, which can quietly affect memory and focus.
-
Hearing and vision: untreated hearing and vision loss make the brain work harder and are linked to higher dementia risk.
-
Mood and stress: low mood, anxiety and ongoing stress can look a lot like memory trouble.
-
Your medications: some common medicines can cloud thinking, especially when taken together.
Core takeaway: Brain fog has many causes, and many of them can be found and treated.
Part I
3. The Quiet Years
When the right time is to look deeper
Changes in the brain often begin long before anyone notices a problem. According to the Alzheimer's Association, the brain changes linked to Alzheimer's disease may begin 20 years or more before a diagnosis.
During these quiet years, a person usually feels fine. The brain is remarkably good at compensating, so small changes can stay hidden for a long time.
There is encouraging news. The 2024 Lancet Commission on dementia found that up to 45% of dementia cases worldwide may be linked to 14 risk factors that can be changed or treated, including high blood pressure, diabetes, high LDL cholesterol, hearing loss, untreated vision loss, depression, smoking, inactivity and social isolation.
That makes these quiet years the most valuable time to act. The risk factors that matter most for the brain can often be addressed long before memory is affected.
Part II
Signs It's Time to Look Deeper
Signs that now is the right time to look deeper
-
You are in your mid-50s or beyond and have never had your memory or thinking checked.
-
You've noticed changes in memory, focus or word-finding, even small ones.
-
Dementia, Alzheimer's disease or stroke runs in your family.
-
You have high blood pressure, diabetes, high cholesterol or have been told they are "borderline."
-
You have trouble hearing, sleep poorly or have been told you snore heavily.
-
You feel well and want a baseline so future changes can be measured against something real.
That last one matters more than people expect. A baseline taken while you feel sharp becomes the reference point for every decision afterward.
Core takeaway: Your brain's future is shaped in the years when you feel fine, and the best time to check your memory is while it's still working well.
4. How Your Brain Health Works Together
Where the pieces connect
The brain doesn't work alone. How well it thinks and remembers depends on the rest of the body. Here's who's involved.
Blood vessels (the supply lines). The brain uses a large share of the body's blood and oxygen. High blood pressure, high blood sugar and high cholesterol can damage the small vessels that feed it.
Sleep (the overnight cleanup). During deep sleep, the brain clears out waste and stores the day's memories. Poor sleep, or untreated sleep apnea, interrupts that work.
Hormones and nutrients (the fuel and signals). Thyroid hormone, vitamin B12 and other nutrients help brain cells work properly. When they are low, thinking can slow down.
Hearing and vision (the inputs). When hearing or eyesight fades, the brain strains to fill in the gaps and gets less of the stimulation it needs.
Mood, movement and connection (the protectors). Physical activity, a steady mood and time with other people all help keep the brain active and resilient.
When one part struggles, the brain feels it. That's why we look at the whole system, not memory alone.

5. Today's Numbers, Tomorrow's Freedom
Why this protects your long-term vitality
There is a difference between lifespan (how long you live) and healthspan (how long you live well). A clear mind is at the heart of living well.
Protecting your brain health can mean:
-
Staying independent. Managing your own home, finances, driving and decisions for longer.
-
Sharper focus and steadier energy. Less fog, better concentration, more good days.
-
Finding treatable causes early. Many causes of memory trouble can be improved once they are found.
-
Lower risk over time. Managing blood pressure, blood sugar, hearing, sleep and mood supports the brain for years to come.
-
Peace of mind. Clear answers are easier to live with than quiet worry.
The goal is not to fear every forgotten name. The goal is to protect the systems that let you keep doing what you love: traveling, keeping up with grandchildren, staying sharp in your work.
Core takeaway: Protecting your memory is protecting your independence.
