How to deal with unexpected traumatic events
Psychological shock is when you experience a surge of strong emotions and a corresponding physical reaction, in response to a (typically unexpected) stressful event.
Why do we have these symptoms?
These symptoms are all part of the body's acute fight, flight, or freeze response. Your body prepares you for fast, thoughtless action. For example, blood rushes to the muscles in your limbs ready for you to spring into activity; we tend to hyperventilate as well, which leads to the cognitive symptoms of feeling spacey and foggy.
What should you do?
Since it's hard to think straight when you're in shock, you should give yourself a chance to calm down before acting, unless quick action is necessary. You may be tempted to make a poor decision.
What happens next?
Since you've gotten a surge of stress hormones released into your bloodstream, it's going to take some time—perhaps a few hours—for your body to get back to its normal state.
What is the sympathetic response?
The sympathetic response is colloquially known as the " fight or flight " response, indicated by accelerated pulse and respiration rates, pupil dilation, and a general feeling of anxiety and hyper-awareness. This is caused by the release of epinephrine and norepinephrine from the adrenal glands.
What is sympathetic stress disorder?
Sympathetic acute stress disorder is caused by the release of excessive adrenaline and norepinephrine into the nervous system. These hormones may speed up a person's pulse and respiratory rate, dilate pupils, or temporarily mask pain.
How long does it take for stress to go away?
In cases where the stress continues, the symptoms usually begin to diminish after 24–48 hours and are usually minimal after about three days. Evaluation of patients is done through close examination of emotional response.
When was ASD first diagnosed?
The APA officially included the term ASD in the DSM-IV in 1994. Before that, symptomatic individuals within the first month of trauma were diagnosed with adjustment disorder. According to the DSM-IV, acute stress reaction refers to the symptoms experienced immediately to 48 hours after exposure to a traumatic event.
What is the opposite of sympathetic?
This response is fairly often triggered by the sight of blood. In this stress response, the body releases acetylcholine. In many ways, this reaction is the opposite of the sympathetic response, in that it slows the heart rate and can cause the patient to either regurgitate or temporarily lose consciousness. The evolutionary value of this is unclear, although it may have allowed for prey to appear dead to avoid being eaten.
How effective is cognitive behavioural therapy?
Cognitive behavioural therapy, which includes exposure and cognitive restructuring, was found to be effective in preventing PTSD in patients diagnosed with acute stress disorder with clinically significant results at six-month follow-up appointments.
Does PTSD resolve itself?
This disorder may resolve itself with time or may develop into a more severe disorder, such as PTSD. However, results of Creamer, O'Donnell, and Pattison's (2004) study of 363 patients suggests that a diagnosis of acute stress disorder had only limited predictive validity for PTSD. Creamer et al. found that re-experiences of the traumatic event and arousal were better predictors of PTSD. Early pharmacotherapy may prevent the development of post-traumatic symptoms. Additionally, early trauma-focused cognitive behavioural therapy (TFCBT) for those with a diagnosis of ASD can protect an individual from developing chronic PTSD.
