The Signs of Depression, Anxiety and PTSD Most People Miss

Mental Health Awareness Month is a reminder that millions of Americans live with depression, anxiety, post-traumatic stress disorder (PTSD), and other mental health conditions, often for months or years before they recognize the symptoms for what they are. At Serenity Mental Health Centers, our psychiatrists see this pattern every day. Patients arrive describing trouble sleeping, difficulty concentrating, or persistent irritability, then discover that those symptoms are connected to something larger.

This guide covers the signs that are most commonly overlooked, the evidence-based outpatient treatments available including Transcranial Magnetic Stimulation (TMS) therapy and ketamine infusion therapy, and how to know when it may be time to speak with a psychiatrist.

What Are the Mental Health Symptoms People Most Often Overlook?

Mental health conditions don’t always announce themselves the way most people expect. The clearest cues, such as persistent sadness, panic attacks, or intrusive thoughts, are also the ones patients are most likely to recognize. The earlier, quieter signs are the ones that go unaddressed, sometimes for years.

According to Dr. TeeJay Tripp, DO, Chief Medical Officer at Serenity Mental Health Centers, the symptoms most frequently dismissed or attributed to other causes include:

  • Persistent sleep disruption that doesn’t respond to lifestyle changes, including difficulty falling asleep, waking early, or sleeping a full night without feeling rested
  • Difficulty concentrating or “brain fog” that interferes with work, school, or daily tasks
  • Irritability or short temper that feels out of character
  • Loss of interest in activities the person previously enjoyed
  • Physical fatigue without a clear medical cause


These symptoms often appear before more recognizable warning signs. Many of them overlap with the early indicators of more familiar conditions.

Patients researching what they’re experiencing often start by looking up the signs of depression in adults, the signs of an anxiety disorder, the symptoms of PTSD, or an adult ADHD symptoms list.

Sleep deserves attention as a signal rather than a standalone problem. Persistent sleep disruption is rarely the underlying condition. It is typically a co-occurring symptom of depression, anxiety, or PTSD that improves when the underlying condition is addressed.

2024 Patient Outcomes Data: Mental Health Trends From the Serenity Network

Across more than 35 outpatient mental health clinics, Serenity Mental Health Centers providers most frequently treated:

78.6%
of patients treated for anxiety
75.6%
of patients treated for depression
22.7%
of patients treated for PTSD
16.3%
of patients reported sleep disturbances as a co-occurring symptom of another diagnosis

These numbers reflect what Serenity’s psychiatrists see clinically. The most common conditions are also the most likely to occur together. A patient diagnosed with depression often presents with anxiety symptoms. A patient with PTSD often experiences sleep disruption. Treatment planning at Serenity considers a patient’s full symptom picture, not just the one that brought them in.

What Is Transcranial Magnetic Stimulation (TMS) Therapy?

Transcranial Magnetic Stimulation (TMS) therapy is a non-invasive, FDA-cleared outpatient treatment that uses magnetic pulses to stimulate areas of the brain associated with mood regulation. Unlike medication, which affects brain chemistry throughout the entire body, TMS therapy targets specific neural pathways involved in conditions such as major depressive disorder (MDD), obsessive-compulsive disorder (OCD), and anxiety.

In Serenity’s 2024 patient outcomes:

  • 84% of TMS patients responded to treatment
  • 78% of TMS patients achieved remission
  • Three years or longer of sustained results for many patients
 

Serenity uses BrainsWay® Deep TMS™ technology, which is FDA-cleared for MDD and OCD. Deep TMS reaches deeper neural regions than standard TMS, allowing precise stimulation of the brain areas involved in mood, attention, and impulse regulation. TMS therapy is administered in an outpatient mental health clinic setting, requires no anesthesia or sedation, and allows patients to resume normal daily activities the same day.

Patients evaluating TMS therapy generally have a few questions early in the process. Many want to know what to expect during a TMS session, whether their plan offers TMS therapy insurance coverage, and how outcomes compare for TMS for treatment-resistant depression versus continued medication management. Serenity’s care coordinators help patients work through each of these as part of the consultation process.

What Is Ketamine Infusion Therapy and How Does It Work?

Ketamine infusion therapy is administered intravenously by a registered nurse in a controlled outpatient setting. It is increasingly recognized for its rapid impact on treatment-resistant depression, post-traumatic stress disorder (PTSD), OCD, and severe anxiety. Many patients experience meaningful symptom relief within hours of their first treatment session.

A typical course at Serenity is approximately six sessions. Each session lasts about two hours, and patients are encouraged to bring a book, music, or another comfortable activity. Ketamine infusion therapy is administered under continuous medical supervision and is considered following an evaluation by a Serenity psychiatrist.

Patients often want to understand what a ketamine therapy session looks like before scheduling a consultation, along with how ketamine therapy for treatment-resistant depression compares with other treatment paths. Both are covered in greater detail elsewhere on the Serenity site.

Serenity’s Integrated Approach to TMS Therapy and Ketamine Infusion Therapy

Serenity Mental Health Centers takes an integrated approach to outpatient mental health care, combining evidence-based treatments rather than relying on any single therapy in isolation. Two of Serenity’s distinguishing approaches are the integration of structured gratitude practice into TMS therapy sessions and, when clinically appropriate, the coordination of TMS therapy with ketamine infusion therapy in a single treatment plan.

TMS Therapy Combined with Gratitude Practice

During TMS therapy sessions at Serenity, providers incorporate structured gratitude practices designed to support patients in developing a more resilient mindset alongside the neurological effects of the treatment itself. The approach is grounded in published research, including a foundational 2003 study by Emmons and McCullough, which found that participants who maintained a regular gratitude practice reported reduced physical symptoms and higher engagement with their care. At Serenity, gratitude practice is positioned as a complement to TMS therapy, not a replacement, and is integrated into the patient’s session experience rather than offered as a separate program.

The Serenity team has written more about this approach in TMS therapy and gratitude practice as a dual approach.

Combination Treatment with TMS Therapy and Ketamine Infusion Therapy

Serenity is one of the few outpatient mental health providers in the United States offering coordinated combination treatment that pairs TMS therapy with ketamine infusion therapy in a single patient care plan. For patients with severe or treatment-resistant conditions, Serenity psychiatrists may recommend integrating the two treatments based on the patient’s diagnosis, treatment history, and clinical evaluation. Combination treatment is not the right approach for every patient. For those who qualify, it allows Serenity providers to address both the rapid-onset relief that ketamine infusion therapy can offer and the longer-term neuromodulation benefits of TMS therapy.

Who Is a Candidate for TMS Therapy or Ketamine Infusion Therapy?

Candidates for TMS therapy generally include adults with a diagnosed mood disorder who have not responded fully to medication management, or who are seeking a treatment path that doesn’t rely on daily medication. Conditions that may benefit from TMS therapy include depression, anxiety, PTSD, and OCD.

Candidates for ketamine infusion therapy generally include adults with treatment-resistant depression, bipolar depression, PTSD, severe anxiety, or who have not experienced full relief from traditional medication management.

Both treatments are administered on an outpatient basis. A consultation with a Serenity psychiatrist determines candidacy and treatment plan. Serenity Mental Health Centers does not provide traditional talk therapy and encourages patients to continue with their existing therapists during and after treatment.

Why Mental Health Care Is Shifting Beyond Medication-Only Approaches

Approximately 30% of people diagnosed with major depressive disorder develop treatment-resistant depression, where two or more antidepressants fail to relieve symptoms (Cleveland Clinic). For these patients, Harvard Health reports that 50 to 60% experience meaningful improvement with TMS therapy.

“Patients deserve access to the full spectrum of evidence-based options,” Dr. Tripp says. “Medication is the right answer for many people, but it shouldn’t be the only answer. TMS therapy and ketamine therapy give us a way to reach patients who have been cycling through medications without relief.”

This shift reflects a broader change in psychiatry. Medication remains an important part of mental health care, but it is increasingly understood as one option within a larger toolkit. For patients who have not responded to medication, alternatives to antidepressants include neuromodulation therapies such as TMS, evidence-based protocols like ketamine therapy, and personalized treatment planning that considers each patient’s full symptom picture.

Frequently Asked Questions About Mental Health Awareness Month and Treatment Options

What is Mental Health Awareness Month?

Mental Health Awareness Month, observed every May since 1949, is a national effort to raise awareness about mental health conditions, reduce stigma, and connect people with care. Organizations such as the National Alliance on Mental Illness (NAMI), the Substance Abuse and Mental Health Services Administration (SAMHSA), and Mental Health America lead awareness initiatives throughout the month.

The signs of depression most often overlooked include persistent sleep disruption, difficulty concentrating, irritability, loss of interest in previously enjoyed activities, and unexplained physical fatigue. These symptoms often appear before more recognizable signs such as persistent sadness, and they are frequently attributed to stress, age, or general lifestyle factors.
Adult anxiety disorders often present as excessive worry that interferes with daily activities, physical symptoms such as muscle tension or rapid heartbeat, sleep disturbances, avoidance of certain situations, and difficulty concentrating. A qualified psychiatrist can evaluate symptoms and determine whether they meet the criteria for generalized anxiety disorder, panic disorder, social anxiety, or another condition.
Common symptoms of adult ADHD include difficulty focusing, executive dysfunction (challenges with planning, organization, and follow-through), impulsivity, restlessness, and difficulty completing tasks. Many adults with ADHD were not diagnosed in childhood. A psychiatrist can perform a clinical evaluation to determine whether a formal diagnosis is appropriate.
TMS therapy targets specific neural pathways in the brain using magnetic pulses, while medication alters brain chemistry throughout the entire body. TMS therapy is non-invasive, FDA-cleared for major depressive disorder and OCD, and typically does not produce the systemic side effects associated with antidepressant medication. TMS is often considered for patients who have not responded to medication or who prefer a non-medication approach.

Many insurance plans, including major commercial insurers, Medicare, and Tricare, cover TMS therapy insurance coverage for major depressive disorder when specific clinical criteria are met. Serenity’s care coordinators work with patients to verify benefits and navigate insurance approval.

A standard course of TMS therapy at Serenity involves approximately 36 sessions over six to eight weeks, with each session lasting 20 to 40 minutes depending on the protocol. Accelerated TMS protocols, which compress treatment into one to two weeks with multiple sessions per day, are also available for eligible patients.
Ketamine therapy is considered safe when administered by trained medical professionals in a controlled clinical setting. At Serenity, ketamine infusions are administered intravenously by a registered nurse under continuous medical supervision. Each session includes pre-session evaluation and post-session monitoring.
Candidates for ketamine therapy generally include adults with treatment-resistant depression, bipolar depression, PTSD, severe anxiety, or thoughts of self-harm. Candidacy is determined through evaluation by a Serenity psychiatrist, who considers diagnosis, treatment history, and overall health.
Yes. Serenity is one of the few outpatient mental health providers in the United States offering coordinated combination treatment with both TMS therapy and ketamine therapy. The decision to combine the two treatments is made by a Serenity psychiatrist based on the patient’s diagnosis, treatment history, and clinical evaluation. Combination treatment is most often considered for patients with severe or treatment-resistant conditions who have not responded fully to a single therapy.

Serenity Mental Health Centers incorporates structured gratitude practice into the patient’s TMS therapy session experience. The approach is grounded in published research, including the Emmons and McCullough 2003 study on gratitude and well-being, which linked regular gratitude practice with improved engagement in care and reduced symptoms. Gratitude practice is positioned as a complement to TMS therapy, not as a standalone treatment, and is described in greater detail in TMS therapy and gratitude practice as a dual approach.
