DIAGNOSTIC PSYCHIATRY • LOS ANGELES & PHOENIX

Medical Investigation for Mental Health Optimization

Systematic root-cause investigation identifies the underlying medical factors—thyroid function, nutritional status, sleep quality, hormones—that limit mental clarity, energy, and mood. Whether you're struggling with treatment-resistant symptoms or seeking to optimize from 'functional' to 'exceptional,' comprehensive medical-psychiatric assessment changes outcomes.

Most patients achieve significant lasting improvement within 2-3 months through root-cause investigation.

Once optimized, quarterly 20-30 minute check-ins maintain wellness long-term—not endless weekly therapy.

This contrasts with standard psychiatric care where only 30-40% of patients experience adequate symptom improvement, often requiring ongoing intensive treatment without clear resolution.

What Is Diagnostic Psychiatry?

40%

of complex psychiatric symptoms have underlying medical causes that standard psychiatric evaluation typically misses—thyroid dysfunction, nutritional deficiencies (B12, iron, vitamin D), undiagnosed sleep apnea, hormonal imbalances, chronic inflammation, medication interactions. When these go unidentified, patients cycle through multiple medications without improvement.

This is why I spend 75-90 minutes in initial evaluations, not 15 minutes. Why I order comprehensive medical workups. Why I look at the whole picture before recommending treatment.

What We Investigate

  • Complete review of medical history and current medications

  • Assessment for thyroid, metabolic, and hormonal factors

  • Evaluation of nutritional deficiencies (B12, iron, folate, vitamin D)

  • Sleep quality and potential sleep disorders

  • Medication interactions and side effects

  • Other systemic medical factors affecting mental health

What We Investigate: 8 Body Systems That Affect Mental Performance

Comprehensive medical-psychiatric assessment systematically examines physiological factors across multiple body systems. Here's what we look at:

Endocrine System

Thyroid, cortisol, sex hormones

Complete thyroid panel (TSH, free T3, free T4, reverse T3, antibodies), cortisol patterns, testosterone, estrogen. Thyroid dysfunction alone affects 15-20% of depression cases.

Nutritional Status

Vitamins, minerals, deficiencies

Vitamin D, B12, folate, iron/ferritin, magnesium. Deficiencies directly impair neurotransmitter production—B12 deficiency alone can mimic depression for years.

Sleep Architechture

Thyroid, cortisol, sex hormones

Screening for undiagnosed sleep apnea (80% undiagnosed in psychiatric populations), circadian rhythm disorders, sleep quality assessment. Poor sleep mimics and worsens psychiatric symptoms.

Cardiovascular Health

Blood pressure, heart medications

Blood pressure effects on cognition, cardiac medication impacts on mood (beta-blockers commonly cause depression), autonomic nervous system function.

Metabolic Function

Blood sugar, insulin, energy

Insulin resistance, glucose dysregulation, metabolic syndrome. Blood sugar instability directly affects mood, energy, focus, and anxiety levels.

Medication Interactions

All medications reviewed

19 years ICU experience with complex medication regimens. Many non-psychiatric medications (statins, steroids, blood pressure meds) cause psychiatric side effects.

Inflammatory Markers

Chronic inflammation assessment

C-reactive protein, inflammatory cytokines. Chronic inflammation directly linked to depression—treating inflammation can resolve psychiatric symptoms.

Hormonal Optimization

Reproductive hormones, DHEA

Perimenopause/menopause effects, testosterone optimization, DHEA levels. Hormonal changes significantly impact mood, energy, cognition, and anxiety.

Why this matters: Standard 15-minute psychiatric visits rarely investigate these factors systematically. When medical causes go unidentified, patients cycle through psychiatric medications that can't work—because they're treating symptoms, not causes.

Who Benefits from This Approach

Treatment-resistant symptoms: If you've tried multiple medications or approaches without lasting improvement, systematic medical investigation often reveals why. When the diagnosis is incomplete, treatment effectiveness is limited regardless of which medications are tried.

Optimization from functional to exceptional: Many people experience subtle declines in mental clarity, energy, or mood despite being 'functional' on paper Often these reflect medical factors—suboptimal thyroid function, nutritional deficiencies, sleep issues—that respond quickly to targeted optimization.

The First Visit

75-90 minutes—not a standard 15-minute appointment. We systematically investigate your complete medical history, all current medications (psychiatric and non-psychiatric), symptom patterns, sleep quality, nutritional status, stress factors, and family history. You receive a clear diagnostic plan with specific lab recommendations and targeted next steps.

When we identify and address underlying medical factors—either instead of or alongside psychiatric medications—most patients experience significant improvement within 2-3 months. Accurate diagnosis enables effective treatment rather than prolonged trial-and-error.

After 19 years across 7 ICU specialties at top hospitals (Cedars-Sinai, USC Keck), I developed Diagnostic Psychiatry—a systematic approach applying ICU-level diagnostic investigation to mental health and cognitive optimization. Instead of 15-minute medication checks using trial-and-error, we investigate WHY symptoms occur through comprehensive medical-psychiatric assessment.

REAL PATIENT OUTCOMES

What Happens When We Find the Root Cause

These outcomes represent what's possible when you investigate thoroughly first— not after years of failed treatments.

THYROID-INDUCED ANXIETY

"I tried two different antidepressants for anxiety. Nothing helped. First visit here, they noticed I was always cold and my hair was thinning. Thyroid test showed severe hypothyroidism that had been missed. Within 6 weeks of proper thyroid treatment, I felt like myself again."

TIME TO RESOLUTION

6 weeks

— Marketing Director, Age 42
Medical Cause: Undiagnosed hypothyroidism

MEDICATION SIDE EFFECT

"I was being treated for depression, but the medication review revealed my blood pressure medication was actually causing depressive symptoms. They coordinated with my cardiologist to switch medications. Depression resolved within 3 weeks. No psychiatric medication needed."

TIME TO RESOLUTION

3 weeks

— Sales Executive, Age 58
Medical Cause: Beta-blocker side effects

SLEEP APNEA + DEFICIENCY

"Years of 'treatment-resistant depression.' Comprehensive workup found severe sleep apnea and iron deficiency. After CPAP and iron supplementation, energy returned, mood stabilized. Now I see them quarterly and I'm thriving. I just needed someone to actually investigate."

TIME TO RESOLUTION

10 weeks

— Teacher, Age 35
Medical Causes: Sleep apnea + iron deficiency

COMMON QUESTIONS

What People Ask Before Their First Visit

Will I need ongoing intensive treatment?

No. Once we identify what's wrong and optimize treatment (typically 2-3 months), you transition to quarterly check-ins. The goal is sustained wellness with minimal ongoing intervention—not indefinite intensive care.

What if you don't find a medical cause?

Then we use evidence-based psychiatric treatment. But we've ruled out medical factors first, so we know we're addressing the right thing. Either way, you get clarity and targeted treatment—not years of trial-and-error.

How is this different from standard psychiatry?

We invest significantly more time investigating underlying medical factors BEFORE making treatment decisions. Standard psychiatric care typically begins with medication trial-and-error. We start with systematic investigation to understand what's actually causing symptoms.

Do you accept insurance?

Yes! We accept most major insurance plans including Aetna, Anthem Blue Cross, Cigna, United Healthcare, and Medicare. Contact us to verify your specific plan coverage.

How quickly can I be seen?

Typically 3-5 days for new patients. We know prolonged wait times when you're struggling aren't acceptable. We maintain appointment availability because every month under-optimized matters.

What if I need more frequent visits initially?

That's completely appropriate. We adjust visit frequency based on clinical need, not rigid protocols. Early on, weekly visits are common. As you improve, we space them out. Treatment intensity matches your needs.

What conditions do you treat?

Depression, anxiety, ADHD, trauma/PTSD, and treatment-resistant symptoms. The key difference is we investigate underlying medical contributors for all these conditions—thyroid function, nutritional status, sleep quality, hormonal factors, medication interactions—before or alongside psychiatric treatment.

Do you provide therapy or just medication?

We provide comprehensive psychiatric evaluation, medication management when appropriate, and coordination with other specialists. If you need ongoing weekly therapy, we can refer you to excellent therapists and coordinate care. Our focus is accurate diagnosis and medical management.

Is this only for severe cases?

Not at all. Many patients are already functional but seeking optimization—going from "good" to "great." Others have treatment-resistant symptoms. Both benefit from systematic medical investigation to identify any limiting factors.

What does the first visit cost?

Initial comprehensive evaluation is typically $300-400 depending on insurance. We verify your benefits before your appointment so you know what to expect. Most insurance plans cover psychiatric evaluation with standard copay or coinsurance.
