Transcranial Magnetic Stimulation uses targeted magnetic pulses—similar in strength to those used in MRI imaging—to stimulate specific areas of the brain involved in mood regulation, emotional processing, and the systems that drive symptoms of depression, OCD, anxiety, and other conditions. The magnetic pulses pass painlessly through the skull and induce small electrical currents in the underlying brain tissue, which over the course of treatment helps restore the activity of brain circuits that have become underactive in mental health conditions.
Unlike medication, TMS doesn’t work by changing brain chemistry through drugs that affect the whole body. It works locally, on specific brain circuits, with no systemic effects—no weight gain, no sexual side effects, no fatigue, no cognitive blunting, no daily medication to remember. For many patients, this is the difference between treatment they can sustain and treatment they end up stopping.
TMS has been studied for more than 40 years and has gained significant clinical traction in the past decade. It is one of the most extensively researched mental health treatments available, with strong evidence for its safety and effectiveness in depression specifically and growing evidence for other conditions. Serenity Mental Health Centers considers TMS our signature treatment—it’s the option we reach for most often when traditional approaches haven’t been enough.
TMS is most established for major depressive disorder, with growing applications across other mental health conditions:
Major Depressive Disorder (MDD). This is the primary FDA-approved indication and the most extensively studied use of TMS. TMS is particularly valuable for patients with treatment-resistant depression—those who haven’t responded fully to one or more antidepressant medications—and for patients who can’t tolerate medication side effects. It’s also FDA-approved for depression with anxious distress, which is one of the most common patterns we see.
Obsessive-Compulsive Disorder (OCD). TMS is FDA-approved for OCD using a specific protocol that targets brain circuits involved in obsessive thoughts and compulsive behaviors. For patients with OCD who haven’t responded fully to SSRIs and exposure-and-response-prevention therapy, TMS provides a meaningful additional option.
Anxiety disorders. While not separately FDA-approved for generalized anxiety disorder, TMS shows meaningful benefit for anxiety symptoms, particularly when anxiety co-occurs with depression. The FDA-approved indication for “depression with anxious distress” addresses one of the most common clinical presentations: patients whose depression and anxiety are intertwined.
Post-Traumatic Stress Disorder (PTSD). Growing clinical evidence supports TMS for PTSD, particularly in veterans, active-duty service members, and patients with treatment-resistant trauma symptoms. The Department of Veterans Affairs has incorporated TMS into VA mental health care for some patients, and TMS is increasingly available through DoD channels for service members. For Northern Virginia residents whose PTSD relates to combat service, federal law enforcement work, intelligence community operations, the September 11, 2001 attack on the Pentagon, intimate partner violence, or other sources, TMS can be a meaningful complement to trauma-focused therapy and medication.
Other conditions. TMS is also used for smoking cessation (a specific FDA-approved indication), bipolar depression (under appropriate care), and other conditions where standard treatments haven’t been adequate. Whether TMS is right for your specific situation is a conversation we have during evaluation.
For most patients, TMS is much less involved than they expect. Here’s what happens:
You arrive and sit down. Sessions take place in a comfortable chair, similar to a dental chair, in our Alexandria office. You don’t change clothes, you don’t get an IV, you don’t take any medication, and you don’t need anyone to drive you.
The coil is positioned. A magnetic coil is positioned against the side of your head, targeting specific brain areas based on your diagnosis and treatment protocol. Initial mapping during your first session determines the exact placement and intensity, and after that, the placement is consistent session to session.
Treatment begins. Brief magnetic pulses are delivered through the coil. You’ll feel a tapping sensation at the treatment site—most patients describe it as similar to someone tapping on the side of your head with a pencil. Some patients find this mildly uncomfortable in the first session or two, and most adjust quickly. Treatment cycles between pulses and rest periods over the course of the session.
You’re awake and aware the whole time. Patients can read, watch something on a phone or tablet, listen to music, or just rest. There’s no sedation, no altered mental state, no fog. Many patients use the time to catch up on email, prep for a meeting, or watch a show.
Sessions typically last 19 to 37 minutes depending on the protocol for your condition. The newest TMS protocols are at the shorter end of that range; older protocols are at the longer end.
You leave and go about your day. No recovery time, no driving restrictions, no work restrictions. You can drive yourself back to a Pentagon office, return to post at Fort Belvoir, head into an agency facility, or whatever your day involves.
A standard course of TMS involves daily sessions (Monday through Friday) over 4 to 6 weeks—typically 30 to 36 sessions total. This is the most significant practical consideration with TMS, and it’s worth being honest about: daily clinic visits for over a month is a real commitment.
Why it works this way. The treatment effect builds with repeated sessions over time. The brain circuits TMS targets need repeated stimulation to shift toward a more typical activity pattern, and the treatment course is designed to deliver enough stimulation to produce durable change. Shorter courses don’t work as well.
What patients typically notice during the course. Most patients begin to notice some improvement in the second or third week, though some notice changes earlier and some later. Sleep often improves first. Mood and energy typically follow. The full benefit of treatment is usually clear by the end of the standard course.
Scheduling. We schedule sessions to fit around federal work schedules, military duty hours, family commitments, and the realities of National Capital Region life. Sessions can be early morning (we open at 6:00 AM)—useful for federal workers and service members coming in before duty hours—during long lunch breaks, or late afternoon and evening (we’re open until 9:00 PM weekdays). Our Walker Lane location is accessible from across southern Fairfax County via I-95, the Beltway, and the Franconia-Springfield corridor.
Planning around PCS, deployment, and clearance cycles. For active-duty service members and other patients with anticipated career events, we can help time the 4-6 week course around PCS moves, deployment windows, polygraph or reinvestigation cycles, or other career events. For most patients, the timing flexibility means TMS can fit into life rather than disrupting it.
After the initial course. Some patients respond well to the initial course and don’t need further TMS for an extended period. Others benefit from periodic maintenance sessions—every few weeks or months—to sustain the gains. The pattern that works best for you becomes clear over time, and we adjust accordingly.
Alexandria’s patient population includes a substantial share of federal employees, intelligence community personnel, military officers, defense contractors, and others holding security clearances. Concerns about how mental health treatment affects clearances are among the most common questions we hear—and they deserve direct, accurate answers.
Mental health treatment generally does not disqualify a security clearance. The federal government has specifically encouraged personnel to seek mental health care without fear of clearance consequences, and the Office of the Director of National Intelligence has stated clearly that seeking mental health care is not a barrier to clearance eligibility. The intent of clearance review is to identify untreated conditions that pose security risks—not to penalize people for taking responsible care of their health.
SF-86 Question 21 is more limited than people assume. The current SF-86 Question 21 asks about mental health treatment with specific exceptions for routine outpatient treatment for depression, anxiety, or grief related to common life circumstances. Many forms of routine psychiatric care do not require disclosure under the current standards. The specific application to your situation depends on your circumstances, and we recommend consulting with your security officer, an EAP, or an attorney familiar with clearance law for guidance specific to your case.
TMS specifically has advantages for clearance holders. Compared to medication treatment, TMS:
— Has no prescription record, no pharmacy fill, and no controlled substance involved.
— Has no medication record in pharmacy benefit data or pharmacy benefit manager systems.
— Is a defined treatment course with a clear endpoint, after which patients are not on ongoing medication.
— Has no medication-related side effects that might need to be disclosed in fitness-for-duty contexts.
— Doesn’t require ongoing prescription renewals or pharmacy visits.
Confidentiality and HIPAA. Mental health treatment records are protected by HIPAA, and we do not share information with employers, agencies, or anyone else without your written authorization. The clinical record stays with us and you.
Discretion in practice. Our extended hours mean appointments can fit before or after duty hours without requiring explanations for absence. Our location is professional and unmarked from the outside in a way that respects patient privacy.
Active-duty service members face specific considerations when seeking mental health treatment, and TMS often fits this population particularly well:
No prescription record on fitness-for-duty matters. Antidepressants sometimes require disclosure in fitness-for-duty evaluations, flight physical updates, dive medicals, and other military-specific medical reviews. The disclosure isn’t typically disqualifying, but the requirement creates real stress for service members in particular career tracks. TMS doesn’t generate the medication record that triggers these disclosures.
No side effects affecting operational performance. Many antidepressants cause fatigue, cognitive slowing, sexual side effects, or weight gain—all of which can affect operational performance in ways that matter. TMS doesn’t cause any of these effects, which means treatment supports duty rather than competing with it.
Treatment that doesn’t pull you off duty. TMS sessions take 19-37 minutes, with no recovery time. You can drive yourself back to duty after a session. The treatment course requires daily sessions for 4-6 weeks, which we schedule around duty hours when possible.
Tricare coverage. We accept Tricare, which covers TMS for treatment-resistant depression with prior authorization. We handle the prior authorization paperwork on your behalf.
Coordination with military medicine. For service members already receiving care through Fort Belvoir, Walter Reed, Bethesda, or other military treatment facilities, we can coordinate care alongside those services. TMS is often used to complement, not replace, military mental health care.
Service-specific policies. Each service branch has its own policies on certain treatments, and active-duty service members considering TMS should be aware of any unit-specific or service-specific guidance. We can discuss this during consultation.
On September 11, 2001, American Airlines Flight 77 struck the Pentagon, killing 184 people at the Pentagon and on the aircraft. First responders from Alexandria County, Fort Myer, Alexandria, the Fairfax County Urban Search and Rescue Team, the FBI, and many other agencies responded that day. In the years since, additional 9/11 responders have been diagnosed with serious illnesses including cancers. The Pentagon survivor community, the first responder community, and the broader Northern Virginia population impacted that day include people carrying documented trauma—some of whom have sought treatment, some of whom haven’t, and some of whom have tried standard treatment without full response.
For patients in this population whose PTSD has been resistant to talk therapy and medication, TMS represents a meaningful additional option. The treatment has growing evidence for PTSD specifically, has no medication side effects affecting cognition or alertness, and integrates with continued trauma-focused therapy. We approach this work with the care it deserves.
For patients whose 9/11-related health concerns include cancers and other serious illnesses connected to that day, the World Trade Center Health Program may provide additional resources, including for Pentagon responders.
Beyond clearance-holder, active-duty, and 9/11-related populations, several other patterns make TMS particularly useful for our Alexandria patient population:
Treatment-resistant depression. The largest TMS patient population is people who’ve tried multiple antidepressants without sustained relief. About a third of depression patients don’t respond fully to the first medication tried, and many cycle through two, three, or more before finding (or not finding) sustained benefit. For these patients, TMS represents a fundamentally different mechanism—not another pill, but a different approach to the underlying brain circuit dysfunction.
Healthcare worker TMS. Nurses, techs, EMTs, and clinical staff at Inova Alexandria Hospital, Inova Mount Vernon, and the broader Northern Virginia hospital systems often have concerns about prescription records, credentialing, and DEA registrations that make TMS particularly appealing. Treatment is in-clinic, doesn’t appear in pharmacy data, and doesn’t generate the medication record some patients prefer to avoid.
Veterans. Alexandria has a substantial veteran population. TMS has growing evidence for PTSD and treatment-resistant depression in veterans, and we accept Tricare and VA Community Care.
New mothers preserving breastfeeding. Postpartum depression is common, and many new mothers want to avoid antidepressants while breastfeeding. TMS doesn’t involve any systemic medication, doesn’t pass to the baby, and is compatible with breastfeeding throughout the treatment course.
Older adults on multiple medications. Many of our older patients are already on multiple prescriptions for medical conditions. Adding an antidepressant introduces drug-drug interaction risks. TMS sidesteps that concern entirely because it isn’t a drug, and it’s well-tolerated in older adults.
Treatment that fits the National Capital Region commute. Our Walker Lane location in southern Fairfax County is accessible from across the region via I-95, the Beltway, and the Franconia-Springfield corridor. Our 6:00 AM to 9:00 PM weekday hours mean sessions can fit before or after work, rather than competing with the long commutes that define so much of National Capital Region life.
TMS and medication aren’t competing options—they’re different tools that serve different patient situations, and many patients use both at different points in their treatment. A few key differences:
How they work. Medications work by changing the balance of neurotransmitters throughout the brain (and the body—which is where side effects come from). TMS works locally on specific brain circuits, stimulating activity in regions that have become underactive in mental health conditions. The result is improvement without systemic effects.
Time to effect. Antidepressants typically take 4-8 weeks to show full effect, and patients often don’t know during those weeks whether the medication is going to work. TMS produces gradual improvement during the treatment course, and patients can often feel changes by week 2 or 3.
Side effects. Medication side effects are common and often disabling enough that patients stop treatment before it’s had time to help. TMS side effects are minimal—occasional headache or scalp discomfort during sessions, both of which typically resolve quickly.
Duration of effect. Antidepressants work only as long as you take them daily. TMS produces effects that last beyond the treatment course—often months or longer—and some patients maintain remission for extended periods with occasional maintenance sessions or no additional treatment.
Combining them. Many patients do well on a combination—continuing medication during and after TMS. Some patients eventually taper medication after TMS produces a strong response. These decisions are individualized.
Some patients ask whether TMS is similar to electroconvulsive therapy (ECT). They’re related in concept—both use forms of brain stimulation for treatment-resistant depression—but the experience is very different:
ECT involves general anesthesia, induces a brief therapeutic seizure, typically requires inpatient or outpatient hospital-based delivery with significant recovery time after each session, can produce temporary memory effects, and is reserved for the most severe or treatment-resistant cases. ECT is highly effective for severe depression and remains a valuable treatment in the right circumstances.
TMS is fully outpatient, involves no sedation or seizure induction, has no memory effects, lets you drive yourself home, and is appropriate for many patients who wouldn’t be candidates for ECT or who want to try a less invasive option first. Most patients trying brain stimulation for the first time appropriately start with TMS.
TMS is appropriate for most adults with depression, OCD, anxiety, or PTSD who haven’t fully responded to standard treatments, who want to avoid medication, or who can’t tolerate medication side effects. Specific considerations:
Established diagnosis. A clear diagnosis of one of the conditions TMS treats. We confirm this through our standard evaluation process before recommending TMS.
Prior treatment history. Insurance typically requires documentation of one or more (often two or more) antidepressant medication trials that haven’t worked adequately. Some patients qualify on a first-line basis based on intolerance to medication; others qualify after a treatment history.
No contraindications. The primary contraindications to TMS are metal implants in or near the head (cochlear implants, deep brain stimulators, aneurysm clips, certain dental implants—we assess this carefully) and a history of seizure disorder or significantly elevated seizure risk. Many patients with metal elsewhere in the body, including hip and knee replacements, are fine candidates.
Treatment commitment. The 4-6 week daily session course is the main practical commitment, and we want patients who are ready to engage with it. We work with patients on scheduling, but the time investment is real.
TMS is one of the better-tolerated treatments in psychiatry. Most patients have minimal side effects, and the side effects that do occur are typically mild and temporary:
Common (most patients). Mild headache during or after the session, mild scalp discomfort at the treatment site, brief facial twitching during pulses (the pulses can stimulate nearby facial muscles). These typically resolve within minutes to hours and become less noticeable over the course of treatment.
Less common. Lightheadedness during sessions, mild jaw discomfort if the pulses affect the masseter muscle. These typically resolve with minor coil position adjustments.
Rare. Seizure during treatment is the most serious potential side effect, occurring in well under 1 in 10,000 sessions in patients without seizure risk factors. We screen carefully for seizure risk before treatment and monitor during sessions.
What TMS doesn’t cause. Weight gain. Sexual side effects. Sedation or fatigue. Cognitive blunting. Sleep disturbance. GI issues. Memory problems. Dependency. None of the side effects that drive patients to stop antidepressants are TMS side effects, because TMS isn’t a drug.
Most major insurance plans cover TMS for treatment-resistant depression, and coverage has expanded substantially over the past decade. Plans we work with that typically cover TMS include Aetna, Blue Cross Blue Shield, Cigna, Optum, United Healthcare, Tricare, Medicare, VA Community Care, and many others. Coverage details vary—some plans cover TMS only for depression, others cover OCD and additional indications—and we verify your specific coverage during the consultation process.
Prior authorization. Insurance plans typically require prior authorization for TMS, which involves documentation of your prior treatment history, current diagnosis, and medical necessity. We handle the prior authorization paperwork on your behalf as part of getting started. This typically takes 1-3 weeks, depending on the insurance company.
What patients usually pay. With insurance coverage in place, patients are typically responsible for their plan’s standard cost-sharing—deductibles, copays, or coinsurance—rather than the full cost of treatment. We walk through the financial picture during consultation so there are no surprises.
Starting TMS isn’t a same-day decision. Here’s how the process typically unfolds:
Initial consultation. A thorough evaluation that includes review of your diagnosis, current symptoms, prior treatment history, and goals. We assess whether TMS is likely to help your specific situation and answer your questions about what treatment involves, including any clearance, career, or duty-status considerations.
Screening for contraindications. Review of medical history for metal implants, seizure risk factors, and other considerations that affect TMS candidacy. Most patients clear this screening without issue.
Insurance authorization. Our team submits the prior authorization paperwork to your insurance company. This typically takes 1-3 weeks. We handle this; you don’t.
Treatment planning and scheduling. Once authorization is in place, we schedule your first session and the rest of the course. Sessions are scheduled to fit your actual schedule—federal work hours, military duty cycles, family commitments, and the broader National Capital Region commute.
First session and mapping. The first session takes longer (typically 60-90 minutes) because it includes initial mapping to determine optimal coil placement and intensity for you specifically. After that, sessions are at the standard 19-to-37-minute duration.
Treatment course and follow-up. Daily sessions Monday through Friday for 4-6 weeks. Periodic check-ins to track progress and adjust as needed. End-of-course evaluation and planning for what comes next—whether maintenance sessions, continued medication or therapy, or simply ongoing monitoring.
TMS is most effective when delivered as part of comprehensive psychiatric care, not as a standalone procedure. Our approach integrates TMS with medication management, therapy referrals, and ongoing clinical follow-up. We assess whether co-occurring conditions—anxiety, ADHD, sleep disorders, substance use, medical conditions—are affecting outcomes, and we adjust the broader plan as needed.
Many patients arrive at TMS after years of feeling stuck on medication or after multiple unsuccessful trials. Our goal isn’t just to deliver TMS sessions; it’s to help patients build a sustainable approach to their mental health that works after the initial course ends.
Our Alexandria clinic is led by a board-certified psychiatrist and a psychiatric physician with experience treating mood, anxiety, PTSD, and related conditions:
Dr. Vanessa Freeman, MD — Board-certified Psychiatrist.
Dr. Lan-Anh Tran, DO — Psychiatric Physician.
Our Alexandria team takes a patient-first, evidence-based approach: careful evaluation, transparent conversations about what TMS can and can’t do, and a steady pace that respects how you’re actually doing. With same-week consultations, extended hours, Tricare and VA Community Care accepted, TMS delivered on-site in southern Fairfax County, and discretion that respects the realities of federal, military, and clearance-holding professional life, we’re committed to making this signature treatment fit the way our patients actually live.
TMS is fundamentally an in-person treatment—it can’t be delivered remotely. That makes location matter. Our Alexandria clinic is at 6354 Walker Lane, Suite 450, in the Kingstowne/Franconia area of southern Fairfax County—convenient to Springfield, Mount Vernon, Fort Belvoir (approximately 5 miles south), Lorton, and the broader National Capital Region. The Pentagon is approximately 7 miles north. Patients coming from across southern Fairfax County, Alexandria proper, and Alexandria can typically reach us in 15-25 minutes—and that proximity matters when you’re coming five days a week for several weeks.
