post-traumatic stress disorder post-traumatic stress disorder post-traumatic stress disorder (ptsd) is a mental and behavioral disorder that can develop because of exposure to a traumatic event, such as sexual assault, warfare, traffic collisions, child abuse, domestic violence, or other threats on a person's life. symptoms may include disturbing thoughts, feelings, or dreams related to the events, mental or physical distress to trauma-related cues, attempts to avoid trauma-related cues, alterations in the way a person thinks and feels, and an increase in the fight-or-flight response. these symptoms last for more than a month after the event. young children are less likely to show distress but instead may express their memories through play. a person with ptsd is at a higher risk of suicide and intentional self-harm. post-traumatic stress disorderspecialtypsychiatry, clinical psychologysymptomsdisturbing thoughts, feelings, or dreams related to the event; mental or physical

sexual assaults, being kidnapped, stalking, physical abuse by an intimate partner, and incest or other forms of childhood sexual abuse are more likely to develop ptsd than those who experience non-assault based trauma, such as accidents and natural disasters. those who experience prolonged trauma, such as slavery, concentration camps, or chronic domestic abuse, may develop complex post-traumatic stress disorder (c-ptsd). c-ptsd is similar to ptsd but has a distinct effect on a person's emotional regulation and core identity. prevention may be possible when counselling is targeted at those with early symptoms but is not effective when provided to all trauma-exposed individuals whether or not symptoms are present. the main treatments for people with ptsd are counselling (psychotherapy) and medication. antidepressants of the ssri or snri type are the first-line medications used for ptsd and are moderately beneficial for about half of people. benefits from medication are less than those seen with counselling. it is not known whether using medications and counselling together has greater benefit than either method separately. medications, other than some ssris or snris, do not have enough evidence to support their use and, in the case of benzodiazepines, may worsen outcomes. in the united states, about 3.5% of adults have ptsd in a given year, and 9% of people develop it at some point in their life. in much of the rest of the world, rates during a given year are between 0.5% and 1%. higher rates may occur in regions of armed conflict. it is more common in women than men. symptoms of trauma-related mental disorders have been documented since at least the time of the ancient greeks. a few instances of evidence of post-traumatic illness have been argued to exist from the seventeenth and eighteenth centuries, such as the diary of samuel pepys, who described intrusive and distressing symptoms following the 1666 fire of london. during the world wars, the condition was known under various terms, including 'shell shock', 'war nerves', neurasthenia and 'combat neurosis'. the term "post-traumatic stress disorder" came into use in the 1970s in large part due to the diagnoses of u.s. military veterans of the vietnam war. it was officially recognized by the american psychiatric association in 1980 in the third edition of the diagnostic and statistical manual of mental disorders (dsm-iii). symptoms service members use art to relieve ptsd symptoms. symptoms of ptsd generally begin within the first three months after the inciting traumatic event, but may not begin until years later. in the typical case, the individual with ptsd persistently avoids either trauma-related thoughts and emotions or discussion of the traumatic event and may even have amnesia of the event. however, the event is commonly relived by the individual through intrusive, recurrent recollections, dissociative episodes of reliving the trauma ("flashbacks"), and nightmares (50 to 70%). while it is common to have symptoms after any traumatic event, these must persist to a sufficient degree (i.e., causing dysfunction in life or clinical levels of distress) for longer than one month after the trauma to be classified as ptsd (clinically significant dysfunction or distress for less than one month after the trauma may be acute stress disorder). some following a traumatic event experience post-traumatic growth. associated medical conditions trauma survivors often develop depression, anxiety disorders, and mood disorders in addition to ptsd. substance use disorder, such as alcohol use disorder, commonly co-occur with ptsd. recovery from post-traumatic stress disorder or other anxiety disorders may be hindered, or the condition worsened, when substance use disorders are comorbid with ptsd. resolving these problems can bring about improvement in an individual's mental health status and anxiety levels. ptsd has a strong association with tinnitus, and can even possibly be the tinnitus' cause. in children and adolescents, there is a strong association between emotional regulation difficulties (e.g. mood swings, anger outbursts, temper tantrums) and post-traumatic stress symptoms, independent of age, gender, or type of trauma. moral injury the feeling of moral distress such as a shame or guilt following a moral transgression is associated with ptsd but is distinguished from it. moral injury is associated with shame and guilt while ptsd is associated with anxiety and fear.: 2,8,11 risk factors no quieren (they do not want to) by francisco goya (1746–1828) depicts an elderly woman wielding a knife in defense of a girl being assaulted by a soldier. persons considered at risk include combat military personnel, survivors of natural disasters, concentration camp survivors, and survivors of violent crime. persons employed in occupations that expose them to violence (such as soldiers) or disasters (such as emergency service workers) are also at risk. other occupations that are at higher risk include police officers, firefighters, ambulance personnel, health care professionals, train drivers, divers, journalists, and sailors, in addition to people who work at banks, post offices or in stores. trauma main article: psychological trauma
