A PTSD brain shows an overactive fear center (amygdala), a shrunken memory area (hippocampus), and an underactive emotion-regulating part (prefrontal cortex), leading to heightened threat responses, flashbacks, memory issues, and difficulty controlling emotions, essentially getting stuck in "danger mode" and struggling to distinguish past threats from present safety, notes ProActive Psychology and the Cleveland Clinic.
PTSD is more than an emotional struggle — it physically rewires the brain, altering how fear is processed, memories are stored and emotions are regulated. Key brain regions affected include the amygdala, bed nucleus of the stria terminali, prefrontal cortex and hippocampus.
Neuroimaging studies have demonstrated significant neurobiologic changes in PTSD. There appear to be 3 areas of the brain that are different in patients with PTSD compared with those in control subjects: the hippocampus, the amygdala, and the medial frontal cortex.
Living with PTSD feels like you're living your worst nightmare over and over again. One of the main symptoms of PTSD is having nightmares, or flashbacks, that rehash the traumatic event. People with PTSD relive their traumatic experience over and over again in their minds, while sleeping, awake, or both.
The 2 medicines recommended to treat PTSD in adults are paroxetine and sertraline. Paroxetine and sertraline are both a type of antidepressant known as selective serotonin reuptake inhibitors (SSRIs).
Post-traumatic stress disorder can disrupt your whole life — your education, job, how well you get along with others, physical health and enjoyment of everyday activities. Having PTSD also may raise your risk of other mental health problems, such as: Depression and anxiety disorders. Issues with drugs or alcohol use.
Never use alcohol or other drugs with antianxiety medicine. This could lead to extreme tiredness, confusion, breathing problems, falls, coma, or death. Use only the amount of medicine prescribed to you.
Severe PTSD symptoms can include flashbacks, nightmares, severe anxiety, and uncontrollable thoughts about the traumatic event. Individuals with severe PTSD may also experience avoidance behaviors, such as avoiding places or people that remind them of the traumatic event.
Psychotherapy (talk therapy) is the main treatment for PTSD, especially forms of cognitive behavioral therapy (CBT). This therapy takes place with a trained, licensed mental health professional, such as a psychologist or psychiatrist.
These triggers can be external, such as sights, sounds, smells, or locations that are associated with the trauma. They can also be internal, such as certain thoughts, emotions, or physical sensations that are similar to those experienced during the traumatic event.
To diagnose post-traumatic stress disorder, your healthcare professional likely will do a: Physical exam to check for medical problems that may be causing your symptoms. Mental health evaluation that includes talking about your symptoms and the trauma that led up to them.
One less talked-about effect of PTSD is a strong fear of change, even when it's an expected and positive change like a new job, a graduation, or a vacation.
A neurologist can conduct a thorough evaluation to assess the impact of trauma on the brain and nervous system. This may involve neurological examinations, imaging studies, and psychological assessments to understand the underlying mechanisms contributing to PTSD symptoms.
The course of the disorder varies. Although some people recover within 6 months, others have symptoms that last for 1 year or longer. People with PTSD often have co-occurring conditions, such as depression, substance use, or one or more anxiety disorders.
Common Symptoms of a CPTSD Episode
Intense feelings of anxiety or panic. Flashbacks or intrusive memories of the traumatic event. Overwhelming feelings of sadness or despair. Heightened emotional sensitivity or irritability.
Returning Veterans who suffer from PTSD symptoms may realize they are “out of line” and seek to protect others from their negative emotions. In order to do so, they may feel the need to shut down all emotions, or build a safe place in which to isolate.
Sleeping pils and sedatives (benzodiazepines) aren't suitable for the treatment of PTSD, because there's a risk of becoming dependent on them and they hardly relieve the symptoms. Before starting treatment with medication, it's important to find out how effective it is and what side effects it may have.
When our brain then recognises similarities between our present situation and our past trauma (e.g. a colour, smell or noise), it can activate the fight, flight, freeze, flop or friend response, even if we're not currently in danger.
10 ways to relax when you have PTSD
The highest form of PTSD is considered extreme PTSD, often manifesting as Complex PTSD. It involves chronic symptoms, emotional detachment, and deep psychological distress from prolonged trauma.
Flashbacks play a significant role in the experience of PTSD. They are characterized by vivid and disturbing recollections of the traumatic event, which can feel as if the person is reliving the experience all over again.
The four main antidepressants effective for treating PTSD are sertraline (Zoloft®), paroxetine (Paxil®), fluoxetine (Prozac®)—all SSRIs—and venlafaxine (Effexor®), an SNRI. Additionally, three antipsychotic drugs are used to help treat PTSD: olanzapine, quetiapine, and risperidone.
Key Actions: Cut down on sugar and processed foods and replace them with more complex carbohydrates, such as wholegrain bread, porridge or brown rice. It is helpful to eat what is called a low Glycemic Load (GL) diet that avoids sugar and refined carbohydrates.
Evidence for PTSD pharmacology is strongest for specific selective serotonin reuptake inhibitors (SSRIs)--sertraline (Zoloft) and paroxetine (Paxil)--and a particular serotonin norepinephrine reuptake inhibitor (SNRI), venlafaxine (Effexor) (1,2).
Some factors may make you more vulnerable to developing PTSD, or may make the problems you experience more severe, including: experiencing repeated trauma. getting physically hurt or feeling pain. having little or no support from friends, family or professionals.
