If antidepressants have not brought enough relief, TMS may be worth asking about.

Transcranial magnetic stimulation (TMS) is a non-invasive, FDA-cleared treatment for medication-resistant depression. It uses a brief magnetic field to stimulate specific areas of the brain involved in mood — no anesthesia, no recovery time.

Approximately 20-40% of people with depression do not get adequate relief from medication and psychotherapy alone. For those individuals, TMS offers a non-pharmacological path forward.

At SIA Behavioral Health in Maryville, IL, providers evaluate each person individually to determine whether TMS is a safe and appropriate fit.

If antidepressants have not brought enough relief, ketamine and esketamine may be options worth understanding.

About one-third of people with major depression do not respond adequately to standard antidepressants -- a condition called treatment-resistant depression.

Ketamine works through the glutamate system, a different mechanism than conventional medications, and can produce antidepressant effects within hours to days rather than weeks.

Intranasal esketamine (Spravato) received FDA approval in 2019 for treatment-resistant depression. IV ketamine is offered off-label. Both are administered in a monitored clinical setting.

Providers at SIA Behavioral Health in Maryville, IL evaluate each patient individually to determine whether these treatments are appropriate.

Work stress is normal. But there is a point where it crosses into something that deserves real support.

Persistent sleep problems, emotional numbness, inability to concentrate, and a sense of hopelessness that does not lift on weekends — these are signs that stress has moved into clinical territory.

Burnout, anxiety, and depression each look different and respond to different approaches. A thorough evaluation helps clarify what is actually driving the picture.

SIA Behavioral Health in Maryville, IL offers psychiatric evaluation and telepsychiatry for adults across Metro East St. Louis who are ready to get a clearer answer.

Anxiety that does not lift after the stressful moment passes is not a character flaw. It is a medical experience with identifiable patterns and real treatment options.

Chronic anxiety can look like worry that floats from topic to topic, recurring panic attacks, or a low-level tension that never fully quiets. It often co-occurs with depression and is one of the most common reasons people seek psychiatric care.

A psychiatric evaluation looks at the full picture -- history, sleep, functioning, prior treatments -- before recommending a plan. That plan may include therapy, medication, or for those who have not responded to standard treatments, options like TMS or ketamine-based therapies.

Providers at Southern Illinois Associates, LLC in Maryville, IL offer comprehensive evaluation and individualized care for persistent anxiety across the Metro East St. Louis area.

Meet Anna Zarlingo, FNP — she leads our Spravato and ketamine clinic.

Anna came to advanced psychiatric care the long way around. A computer science degree first, then twelve years as an emergency department nurse, then family nurse practitioner.

That ER background matters more than it might sound. Spravato and ketamine treatment are given under observation, and they ask for a clinician who monitors closely, reads a room quickly, and stays steady when something needs attention. Anna spent over a decade doing exactly that.

She now runs the day-to-day operations of both programs alongside Dr. Nigam, working with people whose depression has not responded to standard antidepressants. She is board certified through both the ANCC and the AANP.

Anxiety that will not go away deserves a real explanation, not reassurance that everything is fine.

Chronic anxiety has real, identifiable patterns -- generalized worry, panic attacks, social avoidance -- and it responds to treatment.

A psychiatric evaluation matches the right approach to what is actually driving your symptoms. Options range from therapy and medication to TMS and ketamine-based care for those who have not found enough relief.

A 2026 Lancet Psychiatry study of nearly 100,000 people found semaglutide, not every GLP-1 drug, linked to a 42% lower risk of worsening depression or anxiety. Here is what that actually means.

Patients taking semaglutide are already asking at medication management visits whether the mood changes they notice are real. The short answer: for semaglutide specifically, the evidence is genuinely interesting, though not every GLP-1 drug showed the same effect.

A 13-year Swedish cohort study found semaglutide linked to fewer psychiatric hospitalizations and less mental health-related sick leave; liraglutide showed a smaller benefit, and two older GLP-1 drugs showed none. These drugs are not FDA-approved for depression or anxiety, the study was observational, and it is not a substitute for psychiatric care.

At SIA Behavioral Health in Maryville, IL, providers evaluate the full clinical picture when metabolic and mood conditions overlap.

When two or more antidepressants have not brought enough relief, a different approach may be warranted.

Spravato (esketamine) is an FDA-approved nasal spray for treatment-resistant depression -- a condition affecting roughly 30% of people undergoing pharmacotherapy for major depression.

Unlike standard antidepressants that target serotonin or norepinephrine, esketamine works through the brain's glutamate system and can produce antidepressant effects more rapidly.

Every dose is administered at a certified clinical site with post-dose monitoring. Providers at SIA Behavioral Health in Maryville, IL conduct individualized evaluations to determine whether Spravato is appropriate for each patient.

A new kind of ADHD medication called centanafadine is approaching an FDA decision, and the mechanism behind it is genuinely different from most current options.

Most ADHD medications target dopamine and norepinephrine. Centanafadine targets all three: dopamine, norepinephrine, and serotonin. That triple-reuptake profile may address emotional reactivity alongside attention and impulse control.

It is also a non-stimulant, meaning it would not carry Schedule II controlled-substance status. For patients who have not done well on stimulants, or for whom a non-controlled option matters, that distinction is significant.

Providers at SIA in Maryville, IL evaluate each patient's full symptom picture before recommending any treatment path.
