Healing the Mind by Treating the Biology That Drives It.
Standard psychiatry treats mental symptoms in isolation. We bridge autonomic cardiology, neurovascular dynamics, and neuropsychiatry into an integrated clinical sanctuary for complex, treatment-resistant conditions.
Where Cardiology Meets the Mind
Mental exhaustion, intractable panic, and treatment non-response are rarely isolated cognitive failures. They are biochemical reflections of autonomic nervous system overload and microvascular hypoperfusion.
Autonomic Dysregulation & HRV
Heart rate variability and vagal tone serve as our direct physiological window into chronic fight-or-flight states. When vagal braking fails, the amygdala remains trapped in hyper-arousal regardless of psychotropic dosing.
Cerebral Perfusion & Vascular Load
Postural shifts and microvascular resistance govern oxygen and glucose delivery to prefrontal networks. Undiagnosed hypoperfusion produces identical symptoms to panic disorder, severe derealization, and brain fog.
Precision Systemic Remission
We transcend blunt trial-and-error pharmacology. Every prescription and behavioral protocol is customized around your autonomic telemetry, mitochondrial markers, and metabolic baseline for lasting resilience.
Designed for Complex & Treatment-Resistant Cases
Our diagnostic sanctuary is purposefully engineered for individuals who have tried multiple standard lines of treatment without enduring relief, often told their physical sensations are “just stress.”
Treatment-Resistant Panic
Unpredictable adrenergic surges, nocturnal wakeups with racing pulse, and episodic palpitations refractory to standard SSRIs and anxiolytics.
Dysautonomia & POTS
Postural tachycardia, blood pooling, and exercise intolerance accompanied by intense neuropsychiatric exhaustion and sensory overload.
Post-Viral Neuro-Fatigue
Prolonged executive dysfunction, linguistic stumbling, memory latency, and microglial neuroinflammation following viral insults.
Sleep Architecture Disruption
Absence of restorative slow-wave sleep, sympathetically driven micro-arousals, and morning autonomic collapse despite normal polysomnography.
Measured across complex cohorts at 12-month post-intervention follow-ups.
Unrushed, deep biological analysis mapping your complete timeline directly with Dr. Sehgal.
Every review, clinical decision, medication change, and follow-up is managed exclusively by Dr. Sehgal.
Physician-monitored asynchronous secure channel for real-time dosage and symptom refinement.
The Solo Practitioner Difference
Conventional assembly-line clinics split patient care across fragmented sub-specialists and rotating extenders. Neurotonin was built as an uncompromising, single-physician sanctuary.
How Your Care Unfolds
Our onboarding is intentionally thorough. Upon initiating Step 1, you will review Dr. Sehgal’s clinical protocol, submit preliminary symptom metrics, and choose your intake speed.
Physician Match
Care model and state licensure review (NY or MA). Dr. Sehgal personally evaluates clinical compatibility prior to scheduling.
Pre-Intake Bio-Telemetry
Autonomic rhythm tracking and historical medical record synthesis to map baseline orthostatic and physiological variance.
75m Diagnostic Sanctuary
Comprehensive unhurried virtual consultation. A bespoke neuro-cardiac stabilization strategy is deployed same-day.
Begin Your Diagnostic Journey with Dr. Sehgal
Choose between expedited Priority Fast-Track care (within 24–48 hours) or our methodical Standard Clinical Waitlist. Every pathway guarantees complete, unhurried attention directly from Dr. Sehgal.
