Brain health as opposed to mental health is a neglected phenomenon, less discovered now capturing more attention. Currently, the concepts surrounding brain health are vague and no clear definition of this term exists. Assessing brain’s health early in life may offer insights into impending disruptions brain function. If deteriorating or poor health of the brain is detected at a young age, therapeutic steps can be taken. The definition of brain health - “the preservation of optimal brain integrity and mental and cognitive function at a given age in the absence of overt brain diseases that affect normal brain function”. Recently cognitive age has been used as a better indicator of brain health called it the “Cognitive clock”. This book reviews such as fMRI, EEG and PET scan as well as measuring certain blood and CSF biomarker levels. A new noninvasive, cost effective and easily implemented tool for gauging brain health is introduced. This tool can be used in rural communities as well as in LMIC. This book will focus on development of this new tool for brain health measurement, as well as its cross validation in diseased and healthy population.

Dr. Umema Zafar is an accomplished physiologist, educator, and researcher with over a decade of experience in teaching and advancing medical sciences. Currently serving as an Associate Professor of Physiology at HBS Medical College, Islamabad, she holds an MBBS, MPhil, and a PhD in Physiology from Khyber Medical University, Pakistan. Dr. Zafar has been recognized with the prestigious 2022 Research Recognition Award by the American Physiological Society and has served as Vice President of the South Asian Association of Physiologists (SAAP).

Dr. Zafar’s groundbreaking work includes the development of a non-invasive tool to measure brain health and a predictive formula for height estimation based on age, gender, and hand size. Her expertise spans neurophysiology, medical education, and clinical research, with numerous publications and presentations at national and international conferences.

Beyond her professional achievements, Dr. Zafar is deeply committed to social service. She volunteered in the medicine ward at Khyber Teaching Hospital during her undergraduate years and is an active member of professional organizations, including the American Physiological Society and Pakistan Physiological Society. An advocate for continuous learning, she has recently completed a hands-on course in aesthetic medicine, excelling in minimally invasive procedures.
