Your cardiovascular fitness is tracked. Your labs are optimized. Your brain has never been evaluated.
The Cognitive Stability Index™ is a neurologist-designed assessment that identifies which of your core brain systems are under stress — and gives you a precise starting point for addressing them.
Developed by Tanzila Kulman, MD · Board-Certified Neurologist
Takes less than 2 minutes. Science-based. No spam.
This assessment evaluates five clinically relevant brain systems:
Mental Clarity · Focus Stability · Sleep Recovery · Sensory Processing · Brain Energy
High performers notice these patterns first
They don't announce themselves loudly. They accumulate quietly — until the gap between how your brain used to perform and how it performs now becomes impossible to ignore.
Processing speed slows under cognitive load
Sustained attention requires significantly more effort
Sleep stops producing full cognitive recovery
Decision fatigue arrives earlier in the day
Word retrieval, working memory, and mental sharpness feel less reliable
These are not personality traits. They are not inevitable consequences of a demanding life. They are measurable patterns in specific brain systems — and they respond to targeted, evidence-based intervention.

Why I built this
In clinical neurology, I see a predictable pattern. High-functioning patients — executives, physicians, attorneys, entrepreneurs — arrive after years of attributing their cognitive symptoms to stress, poor sleep, or simply the demands of a high-performance life.
By the time they reach my practice, patterns that were addressable early have become entrenched.
The Cognitive Stability Index™ exists because the neurological framework for understanding brain performance should not be reserved for patients who are already in crisis.
You don't need to be symptomatic enough to justify a neurology referral to start understanding your brain.
