Post-Traumatic Stress Disorder (PTSD)
PTSD has many faces
What is PTSD?
Post-traumatic stress disorder, or PTSD, is a mental health condition that can develop after experiencing or witnessing traumatic events such as abuse, violence, accidents, or medical trauma. PTSD affects how the brain processes memory and threat, often keeping the nervous system in a state of alert long after danger has passed. These responses are not a sign of weakness but a brain-based reaction to overwhelming stress.
PTSD can cause intrusive memories, emotional distress, and physical symptoms that interfere with daily life, relationships, work, or school. Trauma-focused therapy and, when appropriate, psychiatric medication can help calm the nervous system and safely process traumatic memories. At Good Day Psychiatry, we provide evidence-based PTSD treatment using Cognitive Processing Therapy and Trauma-Focused Cognitive Behavioral Therapy, with coordinated psychiatric support when needed.
Common PTSD symptoms include intrusive memories or flashbacks, nightmares, avoidance of reminders, emotional numbness, hypervigilance, irritability, and difficulty sleeping or concentrating. Symptoms can vary by person and may change over time, often intensifying during periods of stress. Trauma-focused therapy and, when appropriate, psychiatric medication can help reduce symptoms and improve daily functioning.
What are the symptoms of PTSD?
-
Medication can be helpful for some people with PTSD, especially for symptoms like sleep disruption, anxiety, or mood instability. Medication does not replace therapy, but it can support the nervous system and make therapy more effective. At Good Day Mental Health, medication is individualized and coordinated with trauma-focused therapy.
-
Children and teens with PTSD may show behavioral changes, regression, separation anxiety, irritability, or difficulty at school. Younger children may reenact trauma through play, while teens may withdraw or engage in risk-taking behaviors. Trauma-focused therapy designed for youth can support healthy emotional development and coping.
-
Cognitive Processing Therapy and Trauma-Focused Cognitive Behavioral Therapy are among the most well-researched and effective treatments for PTSD. These therapies help individuals understand and change unhelpful trauma-related thoughts while safely processing memories. Working with a therapist trained in trauma care is key to successful treatment.
-
Some people experience symptom improvement over time, but PTSD often persists without treatment. Avoidance can temporarily reduce distress while reinforcing long-term symptoms. Trauma-focused therapy helps promote lasting recovery and reduces the risk of symptoms becoming chronic.
-
Complex PTSD, often called cPTSD, develops after repeated or prolonged trauma, especially when the trauma occurs in childhood or within relationships where escape was not possible. In addition to core PTSD symptoms, cPTSD involves disruptions in emotional regulation, self-concept, and interpersonal functioning, reflecting long-term changes in stress-response systems and attachment circuitry. Chronic activation of threat pathways affects identity development and relational safety. At Good Day Mental Health, we address cPTSD with specialized trauma-focused therapies that target both memory processing and regulation skills, while psychiatry supports stabilization of mood, sleep, and physiological arousal when needed.
How is PTSD diagnosed?
PTSD is diagnosed through a structured, evidence-based evaluation that examines trauma exposure, symptom patterns, duration, and impact on daily functioning. Clinicians assess core symptom clusters, including intrusion, avoidance, changes in mood and thinking, and hyperarousal, and confirm that symptoms have persisted for more than one month.
A high-quality diagnostic process uses multiple data sources rather than a single checklist, such as a detailed trauma history, standardized measures, and assessment of related conditions like sleep problems or dissociation. At Good Day Psychiatry, psychological expertise in trauma assessment is combined with psychiatric evaluation to guide whether therapy alone is appropriate or whether medication may help support sleep, mood, or physiological regulation.
What causes PTSD?
PTSD develops when the brain’s threat-detection and memory systems are overwhelmed by trauma. Intense stress alters activity in the amygdala, hippocampus, and prefrontal cortex, leading to heightened fear responses, impaired contextual memory, and reduced regulation of emotion. Traumatic memories are stored in a fragmented, sensory-driven way, which helps explain intrusive memories, flashbacks, and strong physical reactions to reminders.
At the neurobiological level, PTSD involves dysregulation of the hypothalamic-pituitary-adrenal axis and ongoing sympathetic nervous system activation. Stress hormones remain out of balance, keeping the body in a state of alert even after danger has passed. At Good Day Psychiatry, this brain-based understanding guides trauma-focused therapy and psychiatric care to support regulation of sleep, mood, and arousal.
