Mental Performance Index

Meaning

The Mental Performance Index (MPI) is a composite metric or score derived from a battery of cognitive tests designed to quantify an individual’s current functional capacity in domains like attention, processing speed, and executive function. This index serves as a quantifiable, objective biomarker of neurological efficiency and can be used to track the impact of hormonal or lifestyle interventions. A higher MPI correlates with improved neuroplasticity and overall cognitive reserve.
