Your blood tests come back normal. Your doctor says everything looks fine. But something is off.
You are waking up tired. Your focus is not what it was. Decisions that used to be effortless now feel
slow. Recovery from stress takes longer than it used to. The evenings that used to restore you no longer
do.
This is not simply ageing. This is your biology telling you something is changing underneath the
surface — in your metabolism, your inflammation levels, your mitochondrial function, your hormonal
balance, your autonomic nervous system.
Conventional medicine is designed to intervene when these changes become disease. Prajeeva is designed to find them years earlier — when they are still measurable, still modifiable and still reversible.
Healthcare has three eras. Medicine 1.0 treated acute illness — infections, injuries, emergencies. Medicine 2.0 manages chronic disease with long-term medication. Medicine 3.0 — the frontier Prajeeva operates in — works decades upstream of both.
The goal is not to treat disease after it appears. The goal is to measure the biological processes that lead to disease, understand them precisely, and intervene before they become irreversible.
Prajeeva combines three disciplines that are rarely found together under one roof :
Investigating Root Causes Rather Than Managing Symptoms

Evidence-Based Protocols That Slow Biological Ageing

Biomarker-Driven, Individually Personalised Protocols That Reveal What Standard Diagnostics Miss

Every patient at Prajeeva begins with a comprehensive baseline assessment. Every intervention is prescribed by a physician, tracked against biomarkers, and measured for outcomes.
This Is Not A Service You Experience. It Is A Clinical Programme You Participate In.
Most people have had their cholesterol checked, their blood pressure monitored and their heart listened to. Very few have had their cognitive function objectively measured.
What we find frequently surprises people. High-performing executives often have measurable deficits in processing speed or sustained attention that they have been compensating for with effort and experience. Identifying these patterns early allows targeted intervention before they progress.
At Prajeeva, every patient receives a comprehensive cognitive assessment covering processing speed, working memory, sustained attention, executive function and reasoning — compared to age and education-matched normative data. For most patients this is the first time they have ever seen an objective picture of how their brain is performing.
A standard annual health check measures a narrow range of markers designed to detect established disease. It will tell you if your LDL cholesterol is above a threshold. It will not tell you your ApoB particle number — the more accurate predictor of cardiovascular risk. It will check your fasting glucose. It will not assess your HOMA-IR — the earliest measurable signal of insulin resistance.
Prajeeva’s clinical technology stack includes interventions with genuine evidence bases in longevity and performance medicine. Each is prescribed by a physician following assessment, sequenced by physiological rationale and tracked against biomarker outcomes.
Prajeeva was founded by two physicians whose combined credential set is unique in the Indian clinical context. Both bring over 25 years of clinical experience to Prajeeva.
MBBS, MS (General Surgery, Bengaluru) • Functional Medicine Certification (USA)
A general surgeon who completed both his MBBS and MS in General Surgery in Bengaluru before pursuing internationally recognised Functional Medicine certification. This dual identity — surgical precision combined with root-cause functional medicine — is the clinical foundation of the Live Longer pillar.
Dr Praveen’s surgical training brings the highest standards of clinical governance, patient safety and diagnostic rigour. His functional medicine training brings the systems-biology framework that drives the root-cause approach at Prajeeva. He holds overall responsibility for clinical standards, protocol design and patient safety.
MBBS (Bengaluru) • MRCPsych, Royal College of Psychiatrists (UK) • CCT in Forensic Psychiatry (UK) • LLM (Master of Laws, UK) • PGDip Clinical Neurology, University College London
UK-trained Consultant Forensic Neuropsychiatrist with one of the most distinctive credential combinations coupled with years of medical leadership experience in the UK. His Royal College of Psychiatrists membership and CCT in Forensic Psychiatry represent the highest standards of UK postgraduate psychiatric training. His Postgraduate Diploma in Clinical Neurology from University College London adds academic neuroscience depth that informs every aspect of the Think Sharper programme.
As CEO, Dr. Vishwanath leads Prajeeva’s overall strategic vision, clinical governance and organisational direction. Clinically, he leads the Think Sharper pillar, applying his forensic neuropsychiatry, neurology and lifestyle medicine training to cognitive longevity, sleep medicine, neurofeedback and the psychological dimensions of high performance.
A Prajeeva programme begins with a comprehensive physician consultation. Not a 15-minute appointment. A 90-minute encounter designed to understand your health history, your goals, your biology and the specific programme most likely to move the needle for you.
