Post-traumatic stress disorder in the context of "Misophonia"

Psychological abuse, often known as emotional abuse or mental abuse, is a form of abuse characterized by a person knowingly or intentionally exposing another person to a behavior that results in psychological trauma, including anxiety, chronic depression, clinical depression or post-traumatic stress disorder amongst other psychological reactions.

It is often associated with situations of controlling behavior in abusive relationships, and may include bullying, gaslighting, abuse in the workplace, amongst other behaviors that may cause an individual to feel unsafe.

Psychological trauma (also known as mental trauma, psychiatric trauma, emotional damage, or psychotrauma) is an emotional response caused by severe distressing events, such as bodily injury, sexual violence, or other threats to the life of the subject or their loved ones; indirect exposure, such as from watching television news, may be extremely distressing and can produce an involuntary and possibly overwhelming physiological stress response, but does not always produce trauma per se. Examples of distressing events include violence, rape, or a terrorist attack.

Short-term reactions such as psychological shock and psychological denial typically follow. Long-term reactions and effects include flashbacks, panic attacks, insomnia, nightmare disorder, difficulties with interpersonal relationships, post-traumatic stress disorder (PTSD), and brief psychotic disorder. Physical symptoms including migraines, hyperventilation, hyperhidrosis, and nausea are often associated with or made worse by trauma.

Rail suicide or suicide by train is deliberate self-harm resulting in death by means of impact from a moving rail vehicle. The suicide occurs when an approaching train hits a suicidal pedestrian jumping onto, lying down on, or walking or standing on the tracks. Low friction on the tracks usually makes it impossible for the train to stop quickly enough. On urban mass transit rail systems that use a high-voltage electrified third rail, the suicide may also touch or be otherwise drawn into contact with it, adding electrocution to the cause of death.

Unlike other methods, rail suicide often directly affects the general public. Trains must be rerouted temporarily to clean the tracks and investigate the incident, causing delays for passengers and crews that may extend far beyond the site, a costly economic inconvenience. Train drivers in particular, effectively forced into being accomplices to the suicide they witness, often suffer post-traumatic stress disorder that adversely affects their personal lives and careers. In recent years railways and their unions have been offering more support to afflicted drivers.

A mass shooting is a violent crime in which one or more attackers use a firearm to kill or injure multiple individuals in rapid succession. Mass shootings with multiple deceased victims are a form of mass murder. There is no widely accepted specific definition of the term, and different organizations tracking such incidents use different criteria. Mass shootings are characterized by the targeting, often indiscriminate, of victims outside a combat setting, and the term generally excludes warfare, gang violence, shootouts, and self-defense. The perpetrator of an ongoing mass shooting may be referred to as an active shooter.

Mass shootings may be done for personal or psychological reasons, such as by individuals who are deeply disgruntled, seeking notoriety, or are intensely angry at a perceived grievance; though they have also been used as a terrorist tactic, such as when members of an ethnic or religious group are deliberately targeted. It has been theorized that media coverage of mass shootings has contributed to later shooters being motivated by fame-seeking. After mass shootings, mental health issues such as survivor's guilt and post-traumatic stress disorder are commonly suffered by survivors, first responders, and victims' loved ones.

Acute stress reaction (ASR), also known as psychological shock, mental shock, or simply shock, as well as acute stress disorder (ASD), is a psychological response to a terrifying, traumatic, or surprising experience. The reactions may include but are not limited to intrusive thoughts, or dissociation, and reactivity symptoms such as avoidance or hyperarousal. It may be exhibited for days or weeks after the traumatic event. If the condition is not correctly addressed, it may develop into post-traumatic stress disorder (PTSD).

Child sexual abuse (CSA), also called child molestation, is a form of child abuse in which an adult or older adolescent uses a child for sexual stimulation. Forms of child sexual abuse include engaging in sexual activities with a child (whether by asking or pressuring, or by other means), indecent exposure, child grooming, and child sexual exploitation, such as using a child to produce child pornography.

CSA is not confined to specific settings; it permeates various institutions and communities. CSA affects children in all socioeconomic levels, across all racial, ethnic, and cultural groups, and in both rural and urban areas. In places where child labor is common, CSA is not restricted to one individual setting; it passes through a multitude of institutions and communities. This includes but is not limited to schools, homes, and online spaces where adolescents are exposed to abuse and exploitation. Child marriage is one of the main forms of child sexual abuse; UNICEF has stated that child marriage "represents perhaps the most prevalent form of sexual abuse and exploitation of girls". The effects of child sexual abuse can include depression, post-traumatic stress disorder, anxiety, complex post-traumatic stress disorder, and physical injury to the child, among other problems. Sexual abuse by a family member is a form of incest and can result in more serious and long-term psychological trauma, especially in the case of parental incest.

A character structure is a system of secondary traits manifested in the specific ways that an individual relates and reacts to others, to various kinds of stimuli, and to the environment. A child whose nurture and/or education cause them to have conflict between legitimate feelings, living in an illogical environment and interacting with adults who do not take the long-term interests of the child to heart will be more likely to form these secondary traits. In this manner the child blocks the unwanted emotional reaction that would have normally occurred. Although this may serve the child well while in that dysfunctional environment, it may also cause the child to react in inappropriate ways, by developing alternate ways in which the energy compulsively surfaces, ways damaging to his or her own interests, when interacting with people in a completely independent environment. Major trauma that occurs later in life, even in adulthood, can sometimes have a profound effect on character. See post-traumatic stress disorder. However, character may also develop in a positive way according to how the individual meets the psychosocial challenges of the life cycle (Erikson).

Mindfulness has been defined in modern psychological terms as "paying attention to relevant aspects of experience in a nonjudgmental manner", and maintaining attention on present moment experience with an attitude of openness and acceptance. Meditation is a platform used to achieve mindfulness. Both practices, mindfulness and meditation, have been "directly inspired from the Buddhist tradition" and have been widely promoted by Jon Kabat-Zinn. Mindfulness meditation has been shown to have a positive impact on several psychiatric problems such as depression and therefore has formed the basis of mindfulness programs such as mindfulness-based cognitive therapy, mindfulness-based stress reduction and mindfulness-based pain management. The applications of mindfulness meditation are well established, however the mechanisms that underlie this practice are yet to be fully understood. Many tests and studies on soldiers with PTSD have shown tremendous positive results in decreasing stress levels and being able to cope with problems of the past, paving the way for more tests and studies to normalize and accept mindful based meditation and research, not only for soldiers with PTSD, but numerous mental inabilities or disabilities.

Four components of mindfulness meditation have been proposed to describe much of the mechanism of action by which mindfulness meditation may work: attention regulation, body awareness, emotion regulation, and change in perspective on the self. All of the components described above are connected to each other. For example, when a person is triggered by an external stimulus, the executive attention system attempts to maintain a mindful state. There is also a heightened body awareness such as a rapid heartbeat which triggers an emotional response. The response is then regulated so that it does not become habitual, but constantly changes from moment to moment experience. This eventually leads to a change in the perspective of the self.

First aid is the first and immediate assistance given to any person with a medical emergency, with care provided to preserve life, prevent the condition from worsening, or to promote recovery until medical services arrive. First aid is generally performed by someone with basic medical or first response training. Mental health first aid is an extension of the concept of first aid to cover mental health, while psychological first aid is used as early treatment of people who are at risk for developing PTSD. Conflict first aid, focused on preservation and recovery of an individual's social or relationship well-being, is being piloted in Canada.

There are many situations that may require first aid, and many countries have legislation, regulation, or guidance, which specifies a minimum level of first aid provision in certain circumstances. This can include specific training or equipment to be available in the workplace (such as an automated external defibrillator), the provision of specialist first aid cover at public gatherings, or mandatory first aid training within schools. Generally, five steps are associated with first aid:
