Hypervigilant
Hypervigilance is a condition in which the nervous system is inaccurately and rapidly filtering sensory information and the individual is in an enhanced state of sensory sensitivity. This appears to be linked to a dysregulated nervous system which can often be caused by traumatic events or complex PTSD. Normally, the nervous system releases stress signals (e.g. norepinephrine) in certain situations as a defense mechanism to protect one from perceived dangers. In some cases, the nervous system becomes chronically dysregulated, causing a release of stress signals that are inappropriate to the situation, creating inappropriate and exaggerated responses. Hypervigilance may bring about a state of increased anxiety which can cause exhaustion. Other symptoms include high responsiveness to stimuli and constant scanning of the environment. In hypervigilance, there is a perpetual scanning of the environment to search for sights, sounds, people, behaviors, smells, or anything else that is re ...

Paranoid Personality Disorder
Paranoid personality disorder (PPD) is a mental disorder characterized by paranoia, and a pervasive, long-standing suspiciousness and generalized mistrust of others. People with this personality disorder may be hypersensitive, easily insulted, and habitually relate to the world by vigilant scanning of the environment for clues or suggestions that may validate their fears or biases. They are eager observers and they often think they are in danger and look for signs and threats of that danger, potentially not appreciating other interpretations or evidence. They tend to be guarded and suspicious and have quite constricted emotional lives. Their reduced capacity for meaningful emotional involvement and the general pattern of isolated withdrawal often lend a quality of loneliness to their life experience. People with PPD may have a tendency to bear grudges, suspiciousness, tendency to interpret others' actions as hostile, persistent tendency to self-reference, or a tenacious sense ...

Nervous System
In biology, the nervous system is the complex system, highly complex part of an animal that coordinates its behavior, actions and sense, sensory information by transmitting action potential, signals to and from different parts of its body. The nervous system detects environmental changes that impact the body, then works in tandem with the endocrine system to respond to such events. Nervous tissue first arose in Ediacara biota, wormlike organisms about 550 to 600 million years ago. In Vertebrate, vertebrates, it consists of two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord. The PNS consists mainly of nerves, which are enclosed bundles of the long fibers, or axons, that connect the CNS to every other part of the body. Nerves that transmit signals from the brain are called motor nerves (efferent), while those nerves that transmit information from the body to the CNS are called sensory nerves (aff ...

Post-traumatic Stress Disorder
Post-traumatic stress disorder (PTSD) is a mental disorder that develops from experiencing a Psychological trauma, traumatic event, such as sexual assault, domestic violence, child abuse, warfare and its associated traumas, natural disaster, traffic collision, or other threats on a person's life or well-being. Symptoms may include disturbing thoughts, feelings, or dreams related to the events, mental or physical distress (medicine), distress to Psychological trauma, 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 and can include triggers such as misophonia. Young children are less likely to show distress, but instead may express their memories through play (activity), play. Most people who experience traumatic events do not develop PTSD. People who experience interpersonal violence such as rape, other sexual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trauma Trigger
A trauma trigger is a psychological stimulus that prompts involuntary recall of a previous traumatic experience. The stimulus itself need not be frightening or traumatic and may be only indirectly or superficially reminiscent of an earlier traumatic incident, such as a scent or a piece of clothing. Triggers can be subtle, individual, and difficult for others to predict. A trauma trigger may also be called a trauma stimulus, a trauma stressor or a trauma reminder. The process of connecting a traumatic experience to a trauma trigger is called traumatic coupling. When trauma is "triggered", the involuntary response goes far beyond feeling uncomfortable and can feel overwhelming and uncontrollable, such as a panic attack, a flashback, or a strong impulse to flee to a safe place. Avoiding a trauma trigger, and therefore the potentially extreme reaction it provokes, is a common behavioral symptom of posttraumatic stress disorder (PTSD) and post-traumatic embitterment disorder (PTED ...

Rheumatoid Arthritis
Rheumatoid arthritis (RA) is a long-term autoimmune disorder that primarily affects synovial joint, joints. It typically results in warm, swollen, and painful joints. Pain and stiffness often worsen following rest. Most commonly, the wrist and hands are involved, with the same joints typically involved on both sides of the body. The disease may also affect other parts of the body, including skin, eyes, lungs, heart, nerves, and blood. This may result in a anemia, low red blood cell count, pleurisy, inflammation around the lungs, and pericarditis, inflammation around the heart. Fever and low energy may also be present. Often, symptoms come on gradually over weeks to months. While the cause of rheumatoid arthritis is not clear, it is believed to involve a combination of genetic and environmental factors. The underlying mechanism involves the body's immune system attacking the joints. This results in inflammation and thickening of the synovium, joint capsule. It also affects the und ...

Fibromyalgia
Fibromyalgia (FM) is a functional somatic syndrome with symptoms of widespread chronic pain, accompanied by fatigue, sleep disturbance including awakening unrefreshed, and Cognitive deficit, cognitive symptoms. Other symptoms can include headaches, Abdominal pain, lower abdominal pain or cramps, and Depression (mood), depression. People with fibromyalgia can also experience insomnia and extreme sensitivity. The causes of fibromyalgia are unknown, with several pathophysiologies proposed. People with fibromyalgia are sometimes accused of imagining their symptoms. Fibromyalgia was first recognised in the 1950s, and defined in 1990, with updated criteria in 2011, 2016, and 2019. Fibromyalgia is estimated to affect 2 to 4% of the population. Women are affected more than men. Rates appear similar across areas of the world and among varied cultures. Symptoms of fibromyalgia are persistent in most patients. The treatment of fibromyalgia is Symptomatic treatment, symptomatic an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chronic Pain
Chronic pain is pain that persists or recurs for longer than 3 months.https://icd.who.int/browse/2025-01/mms/en#1581976053 It is also known as gradual burning pain, electrical pain, throbbing pain, and nauseating pain. This type of pain is in contrast to acute pain, which is pain associated with a cause that can be relieved by treating the cause, and decreases or stops when the cause improves. Chronic pain can last for years. Persistent pain often serves no apparent useful purpose. The most common types of chronic pain are back pain, severe headache, migraine, and facial pain. Chronic pain can cause very severe psychological and physical effects that sometimes continue until the end of life. Analysis of the grey matter (damage to brain neurons), insomnia and sleep deprivation, metabolic problems, chronic stress, obesity, and heart attack are examples of physical disorders; and Depression (mood), depression, and neurocognitive disorders are examples of mental disorders.

Thousand-yard Stare
The thousand-yard stare (also referred to as two-thousand-yard stare) is the blank, unfocused gaze of people experiencing dissociation due to acute stress or traumatic events. It was originally used about war combatants and the post-traumatic stress they exhibited but is now also used to refer to an unfocused gaze observed in people under any stressful situation, or in people with certain mental health conditions. The thousand-yard stare is sometimes described as an effect of shell shock or combat stress reaction, along with other mental health conditions. However, it is not a formal medical term. Origin The phrase was popularized after '' Life'' magazine published the painting ''Marines Call It That 2,000 Yard Stare'' by World War II artist and correspondent Tom Lea, although the painting was not referred to with that title in the 1945 magazine article. The painting, a 1944 portrait of a nameless Marine at the Battle of Peleliu, is now held by the United States Army Cen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flashback (psychology)
A flashback, or involuntary recurrent memory, is a psychological phenomenon in which an individual has a sudden, usually powerful, re-experiencing of a past experience or elements of a past experience. These experiences can be frightful, happy, sad, exciting, or any number of other emotions. The term is used particularly when the memory is recalled involuntarily, especially when it is so intense that the person "relives" the experience, and is unable to fully recognize it as memory of a past experience and not something that is happening in "real time". History Flashbacks are the "personal experiences that pop into your awareness, without any conscious, premeditated attempt to search and retrieve this memory". These experiences occasionally have little to no relation to the situation at hand. For those suffering post-traumatic stress disorder (PTSD), flashbacks can significantly disrupt everyday life. Memory is divided into voluntary (conscious) and involuntary ( unconscious) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anxiety Disorder
Anxiety disorders are a group of mental disorders characterized by significant and uncontrollable feelings of anxiety and fear such that a person's social, occupational, and personal functions are significantly impaired. Anxiety may cause physical and cognitive symptoms, such as restlessness, irritability, easy fatigue, difficulty concentrating, increased heart rate, chest pain, abdominal pain, and a variety of other symptoms that may vary based on the individual. In casual discourse, the words ''anxiety'' and ''fear'' are often used interchangeably. In clinical usage, they have distinct meanings; anxiety is clinically defined as an unpleasant emotional state for which the cause is either not readily identified or perceived to be uncontrollable or unavoidable, whereas fear is clinically defined as an emotional and physiological response to a recognized external threat. The umbrella term 'anxiety disorder' refers to a number of specific disorders that include fears (phobias) and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fixation (psychology)
Fixation () is a concept (in human psychology) that was originated by Sigmund Freud (1905) to denote the persistence of anachronistic sexual traits. The term subsequently came to denote object relationships with attachments to people or things in general persisting from childhood into adult life. Freud In '' Three Essays on the Theory of Sexuality'' (1905), Freud distinguished the fixations of the libido on an incestuous object from a fixation upon a specific, partial ''aim'', such as voyeurism. Freud theorized that some humans may develop psychological fixation due to one or more of the following: #A lack of proper gratification during one of the psychosexual stages of development. #Receiving a strong impression from one of these stages, in which case the person's personality would reflect that stage throughout adult life. #"An excessively strong manifestation of these instincts at a very early age hichleads to a kind of partial ''fixation'', which then constitutes a weak po ...

Sensory Sensitivity
Sensory processing sensitivity (SPS) is a temperamental or personality trait involving "an increased sensitivity of the central nervous system and a deeper cognitive processing of physical, social, and emotional stimuli". The trait is characterized by "a tendency to 'pause to check' in novel situations, greater sensitivity to subtle stimuli, and the engagement of deeper cognitive processing strategies for employing coping actions, all of which is driven by heightened emotional reactivity, both positive and negative". A human with a particularly high measure of SPS is considered to have "hypersensitivity", or be a highly sensitive person (HSP). The terms ''SPS'' and ''HSP'' were coined in the mid-1990s by psychologists Elaine Aron and her husband Arthur Aron, who developed the Highly Sensitive Person Scale (HSPS) questionnaire by which SPS is measured. Other researchers have applied various other terms to denote this responsiveness to stimuli that is seen in humans and other s ...
