Post-traumatic stress disorder, or PTSD, is a mental health condition that can develop after a person experiences or witnesses a frightening, dangerous, or deeply distressing event. It is a natural response to trauma that, for some people, does not fade on its own and begins to interfere with daily life. A person living with PTSD may relive the event, avoid reminders of it, and feel constantly on edge long after the danger has passed.

According to the National Institute of Mental Health, PTSD can affect anyone, at any age, and it is more common than many people realize. It is also treatable. With trauma-informed care and evidence-based therapies, symptoms can ease and a person can regain a sense of safety and control. This guide explains the symptoms, the causes, and the treatment options available at Ascend Recovery Center in Albuquerque.

The four symptom clusters of PTSD

Clinicians group PTSD symptoms into four clusters. A person does not need every symptom in every cluster, and the way symptoms appear varies from one person to another. Understanding these groups makes the condition easier to recognize.

Re-experiencing

Intrusive memories, flashbacks, or nightmares can make the event feel as if it is happening again. Reminders can trigger strong emotional and physical reactions.

Avoidance

A person may avoid places, people, activities, or conversations that recall the trauma, and may try to push away thoughts and feelings connected to it.

Arousal and reactivity

Feeling on guard, being easily startled, having trouble sleeping, and experiencing irritability or difficulty concentrating are common. This is sometimes described as feeling keyed up.

Mood and cognition

Negative changes in thoughts and mood can include persistent fear, guilt, or shame, difficulty remembering parts of the event, feeling detached from others, and losing interest in activities once enjoyed.

What causes PTSD

PTSD can follow many kinds of experiences, including accidents, violence, abuse, combat, natural disasters, the sudden loss of a loved one, or serious illness. Not everyone who lives through trauma develops PTSD. Factors such as the severity of the event, prior experiences, available support, and individual biology all play a part. The condition is not a sign of weakness. It is a recognized response to overwhelming stress.

How PTSD is treated

PTSD responds to structured, evidence-based treatment. At Ascend, care begins with a thorough assessment, and every plan is built around trauma-informed care, which means our clinicians work to create safety and avoid re-traumatization at every step. Treatment can include:

  • EMDR available, delivered by EMDR-trained therapists as part of trauma-informed care
  • Cognitive behavioral therapy (CBT) to process and reframe trauma-related thoughts
  • Dialectical behavior therapy (DBT) to build skills for managing intense emotions
  • Psychiatric services and medication management overseen by our medical directors
  • Family and group therapy, plus wellness activities such as mindfulness and breathwork

When substance use occurs alongside PTSD

Substance use and PTSD frequently occur together. Some people turn to alcohol or other substances to quiet intrusive memories or to sleep, which can deepen both conditions over time. When both are present, integrated dual diagnosis treatment addresses the mental health condition and the substance use disorder at the same time, in one coordinated plan, rather than treating them in isolation.

Frequently Asked Questions

How is PTSD different from a normal stress reaction?
Most people feel shaken after a distressing event, and those feelings usually ease with time. PTSD is diagnosed when symptoms across the four clusters persist, cause significant distress, and interfere with daily life. A clinical assessment can clarify the difference.
Is EMDR offered at Ascend?
Yes. EMDR is available at Ascend and is delivered by EMDR-trained therapists as part of trauma-informed care. It is one of several evidence-based approaches we use to support a person living with PTSD.
Can PTSD be treated successfully?
Yes. PTSD is treatable. With trauma-informed care and evidence-based therapies such as EMDR and CBT, many people experience meaningful relief from symptoms and regain a sense of safety and control.
Why do PTSD and substance use often occur together?
Some people use substances to cope with intrusive memories, hypervigilance, or sleep problems, which can worsen both conditions. When both are present, integrated dual diagnosis treatment addresses them together in one plan.
What does trauma-informed care mean?
Trauma-informed care is an approach in which clinicians recognize the effects of trauma and work to create safety, build trust, and avoid re-traumatization throughout treatment. At Ascend it shapes how every part of care is delivered.
Will insurance help cover treatment?
Under the Affordable Care Act and mental health parity rules, many plans include behavioral health benefits. We are approved for Medicaid, Blue Cross, United Healthcare, and Molina, and we verify each client's specific benefits before they commit to anything.
