Is Your Brain Performing as Reliably as It Should?
Cognitive Stability Index™
A neurologist-designed brain checkup that reveals the hidden instability behind brain fog, sleep disruption, head pressure, and declining focus.
Takes less than 3 minutes.
This Brain Checkup Evaluates Five Core Systems
Mental Clarity | Focus Stability| Sleep Recovery | Sensory Processing | Brain Energy|
Mental Clarity | Focus Stability| Sleep Recovery | Sensory Processing | Brain Energy|

Designed by a Neurologist
Dr. Tanzila Kulman is a board-certified neurologist focused on cognitive health, brain performance, and long-term brain stability.
The Cognitive Stability Index™ was created to help people identify early instability patterns and take meaningful steps toward improving clarity, focus, and recovery.
Your results include:
Your Brain Stability Score
Your Brain Pattern
The first protocol to begin stabilizing your brain
Many high-performing people notice subtle brain changes long before they understand why.
The brain rarely loses performance suddenly.
Instead, specific systems begin to show instability:
Thinking feels slower under pressure
Focus becomes harder to sustain
Sleep stops restoring mental clarity
Head pressure or headaches appear more frequently
Cognitive fatigue builds throughout the day
These patterns are often dismissed as stress or aging.
But they often reflect measurable changes in brain stability.
The Cognitive Stability Index™ was created to help identify these patterns early.
A neurological approach to brain stability
Most people are never taught how the brain’s stability systems function.
As a neurologist, I often see patients only after these systems have already begun to struggle.
The Cognitive Stability Index™ was created to identify early instability patterns and guide the first steps toward improving brain clarity and performance.
This assessment evaluates the systems that influence:
Cognitive clarity
Focus stability
Sleep recovery
Sensory sensitivity
Mental energy
The earlier brain instability is identified, the easier it is to stabilize.
