Functional Psychiatry NYC

Most psychiatric care is built around the diagnosis: identify the symptoms, name the condition, prescribe a treatment. For many patients, that approach is sufficient.

For others, it isn't. Symptoms persist. Medications work partially, or not at all. The diagnosis feels incomplete — and standard evaluations aren't designed to find what's been missed.

Functional psychiatry extends conventional psychiatric practice by investigating the biological systems that directly affect mental health: gut function, inflammation, hormone regulation, nutritional status, and nervous system patterns. At Evolution Medicine, this investigation is conducted by a board-certified psychiatrist with advanced training in functional and regenerative medicine — and integrated with evidence-based psychiatric care, not offered in place of it.


Why Standard Care Sometimes Falls Short

Conventional psychiatry is designed to manage symptoms. That's a reasonable goal — but it's not always sufficient for patients with treatment-resistant presentations, complex co-occurring conditions, or symptoms that don't respond predictably to standard protocols.

When gut permeability affects neurotransmitter production, when systemic inflammation elevates depression risk, when thyroid dysfunction compounds anxiety, when chronic stress disrupts cortisol regulation — these aren't peripheral findings. They're central to the clinical picture. Standard care doesn't routinely test for them. Functional psychiatry does.


Our Approach

Comprehensive Psychiatric Evaluation — We begin with a thorough assessment of your psychiatric history, symptom patterns over time, co-occurring conditions, prior treatments, and treatment responses. Understanding what has and hasn't worked — and why — is the foundation of everything that follows.

Functional & Biological Testing — When clinically indicated, we investigate gut microbiome function, systemic inflammation, thyroid and adrenal function, sex hormone levels, nutritional status, and metabolic markers. Testing is ordered based on clinical relevance — not applied as a routine panel to every patient.

Integrated Treatment Planning — Your plan may combine medication optimization, targeted psychotherapy, nutritional and lifestyle interventions, and nervous system regulation strategies — built around your specific findings, not a standard diagnostic protocol.

Ongoing Evaluation — Functional psychiatry is not a one-time assessment. We track how you respond, adjust accordingly, and work toward sustained improvement — not just symptom control.


Substance Use, Addiction, and the Functional Picture

Substance use frequently has functional underpinnings: nutritional depletion from chronic use, dysregulated stress hormones, gut disruption, and neurological changes that standard care rarely investigates. For patients managing addiction alongside depression, anxiety, or trauma, this deeper assessment is often what makes recovery sustainable.

Dr. Lazarevic is double board-certified in General Psychiatry and Addiction Psychiatry. Many patients in her practice don't identify substance use as their primary concern — yet the physiological effects of use shape their clinical presentation in ways that a functional approach can address directly, without requiring patients to define or label themselves.


What Makes Evolution Medicine Different

Board-Certified Foundation — Functional testing and integrative methods here are applied by a board-certified psychiatrist with advanced training in functional and regenerative medicine — not a wellness provider operating outside psychiatric credentials.

Time and Depth — Initial evaluations are 60–90 minutes. Multifactorial presentations require thorough investigation, not a brief appointment or a predetermined protocol.

Coordinated Care — When appropriate, clinical psychologist Dr. Shuki Cohen, PhD, and functional nutritionist Helaine Polanco, MS, join your care — integrating psychotherapy and nutritional medicine with your psychiatric plan as a unified team.

Have questions? Frequently Asked Questions

  • Patients who tend to benefit most are those with treatment-resistant depression, anxiety that hasn't resolved with standard care, complex presentations involving mood, sleep, and cognition together, and those with a history of substance use or addiction alongside a mental health diagnosis. That said, a functional evaluation can be valuable for anyone who feels their care has focused on symptoms without investigating what's driving them.

  • Testing is individualized and ordered only when clinically indicated. It may include blood panels for thyroid, hormones, and inflammation markers; gut microbiome assessment; nutritional status evaluation; and adrenal function testing. Dr. Lazarevic reviews findings in the context of your full psychiatric picture — not as a standalone lab report.

  • No. Some patients arrive with a clear diagnosis that hasn't responded to treatment. Others arrive uncertain of their diagnosis, or feeling that the label they've been given doesn't fully explain their experience. Both are appropriate starting points for a functional psychiatry evaluation.

  • It varies by case complexity. Some patients see meaningful change within the first few months as targeted interventions take effect. Others, particularly those with long-standing treatment resistance or complex histories, benefit from a longer, more iterative process. Evolution Medicine's Momentum Care™ Packages are designed specifically for patients who require sustained, coordinated care.

  • Yes. Dr. Lazarevic sees patients via telepsychiatry in New York (NY), Connecticut (CT), and California (CA). Patients in other states are welcome to inquire.

Functional psychiatry doesn't replace what you've tried. It investigates what's been missed.
