Understanding PTSD: Symptoms, Causes & Treatment Options
Post-traumatic stress disorder (PTSD) doesn't just affect combat veterans it can develop after any event that overwhelms a person's ability to cope, from a car accident to a medical emergency to ongoing abuse. And because PTSD so often travels alongside depression symptoms, the two conditions are frequently misdiagnosed or only partially treated. This guide walks through what PTSD looks like, what causes it, how it overlaps with depression, and the treatment options that can help you or a loved one move forward.
What Is PTSD?
PTSD is a mental health condition that can develop after exposure to a traumatic event one that involved actual or threatened death, serious injury, or violence. Not everyone who lives through trauma develops PTSD, but for those who do, the effects can persist for months or years without the right care. At Embrace Behavioral Health, we regularly see patients whose PTSD has gone unrecognized because their symptoms were attributed to anxiety, burnout, or simply "stress."
Common Symptoms of PTSD
PTSD symptoms are typically grouped into four categories. Most people don't experience every symptom, and severity varies widely from person to person.
1. Intrusive Memories
Unwanted, distressing memories of the traumatic event
Flashbacks that feel as though the event is happening again
Nightmares related to the trauma
Intense emotional or physical reactions to reminders ("triggers") of the event
2. Avoidance
Avoiding places, people, or activities that bring back memories of the trauma
Refusing to talk or think about what happened
3. Negative Changes in Mood and Thinking
This category overlaps heavily with depression symptoms, which is one reason PTSD and depression are so often diagnosed together. Signs include:
Persistent negative beliefs about oneself, others, or the world
Ongoing feelings of guilt, shame, or blame
Loss of interest in activities once enjoyed
Feeling detached or emotionally numb
Difficulty experiencing positive emotions
4. Changes in Arousal and Reactivity
Being easily startled or constantly "on guard"
Irritability or angry outbursts
Difficulty concentrating
Trouble sleeping
Reckless or self-destructive behavior
What Causes PTSD?
PTSD can develop after any event a person experiences as life-threatening or deeply distressing, including:
Combat exposure or military service
Physical or sexual assault
Serious accidents (car crashes, workplace injuries)
Natural disasters
Childhood abuse or neglect
Sudden loss of a loved one
A frightening medical diagnosis or procedure
A person's individual risk also plays a role. Genetics, prior mental health history, the amount of support available after the event, and even how the brain processes stress hormones all influence whether trauma develops into full PTSD. This is part of why two people can go through the same event and have very different outcomes and it's also why genetic and psychiatric evaluation can be so useful in building an effective treatment plan.
PTSD and Depression: Why They So Often Occur Together
Research consistently shows that a large share of people diagnosed with PTSD also meet the criteria for major depressive disorder. The two conditions share overlapping symptoms low mood, sleep disruption, loss of interest, difficulty concentrating which makes accurate diagnosis essential. Someone might come in describing what sounds like straightforward depression symptoms, when trauma is actually the underlying driver. Without addressing the trauma itself, standard depression treatment alone may fall short.
This is exactly the kind of overlap our team is trained to untangle. Using comprehensive psychiatric evaluation and diagnostic tools that screen for dozens of conditions at once, we're able to see the full clinical picture rather than treating symptoms in isolation.
The Risks of Untreated Depression and PTSD
When PTSD and untreated depression are left unaddressed, the effects tend to compound over time rather than fade on their own. Left untreated, this combination is associated with:
Worsening anxiety and panic symptoms
Damage to relationships, work performance, and daily functioning
Increased reliance on alcohol or other substances to cope
Physical health effects, including chronic pain and cardiovascular strain
A significantly higher risk of suicidal thinking
If you or someone you know is in crisis or having thoughts of suicide, call or text 988 (Suicide & Crisis Lifeline) or go to the nearest emergency room. Support is available, and reaching out is a sign of strength, not weakness. Learn more about what to do in a mental health emergency on our site.
Treatment Options for PTSD
The good news is that PTSD even alongside depression is highly treatable. Effective care typically combines several approaches tailored to the individual:
Comprehensive Psychiatric Evaluation
An accurate diagnosis is the foundation of effective treatment. Our team uses in-depth evaluation, including tools that screen for over 80 mental health conditions, to distinguish PTSD from depression, anxiety, or other overlapping conditions and build a treatment plan around the full picture. Learn more about our approach to integrative psychiatry.
Medication Management
For many patients, medication plays an important role in reducing PTSD and depression symptoms enough to fully engage in therapy. Because response to psychiatric medication varies widely from person to person, our medication management services focus on close monitoring and adjustment over time not a one-size-fits-all prescription.
Genetic Testing
Trial-and-error with psychiatric medication can be frustrating and slow, especially for patients dealing with both PTSD and depression. Our genetic testing services help identify which medications are more likely to be effective for a patient's individual genetic profile, shortening the path to relief.
Trauma-Focused Therapy
Evidence-based therapies designed specifically for trauma such as cognitive processing therapy and EMDR help patients process traumatic memories in a safe, structured way, rather than avoiding them indefinitely. This is often paired with ongoing supportive therapy to address co-occurring depression symptoms.
Ongoing, Coordinated Care
PTSD recovery isn't a single appointment it's an ongoing relationship with a care team that adjusts as you do. To meet the team who will be walking through that process with you, visit our Meet Our Team page.

Frequently Asked Questions
Can PTSD develop without a single "big" traumatic event?
Yes. PTSD can also develop from prolonged or repeated stress, such as ongoing childhood neglect, chronic abuse, or extended exposure to a frightening environment, not only from a single catastrophic incident.
How is PTSD different from generalized anxiety?
While both involve excessive worry and physical tension, PTSD is specifically tied to a traumatic event and includes symptoms like flashbacks, avoidance of trauma-related triggers, and hypervigilance that aren't part of generalized anxiety.
Is it common to have both PTSD and depression?
Yes the two conditions frequently co-occur, and overlapping depression symptoms can make PTSD harder to identify without a thorough evaluation. Addressing both conditions together typically leads to better outcomes than treating either one alone.
How long does PTSD treatment take?
Timelines vary by individual, the nature of the trauma, and whether other conditions like depression are also present. Many patients see meaningful improvement within a few months of consistent treatment, though ongoing care and adjustment are common.
When should I seek help for PTSD or depression symptoms?
If symptoms are lasting more than a few weeks, interfering with work, relationships, or daily functioning, or involve any thoughts of self-harm, it's time to reach out. You can schedule an appointment with Embrace Behavioral Health, and if you're in immediate crisis, call or text 988 or visit our emergency resources page.
