Anxiety

(Redirected from Anxious)

Anxiety is medically recognized as the experience of negative feelings of apprehension, worry, and general unease.[1][2] These feelings can range from subtle and ignorable to intense and overwhelming enough to trigger panic attacks or feelings of impending doom. Anxiety is often accompanied by nervous behaviour such as stimulation, restlessness, difficulty concentrating, irritability, and muscular tension.[3] Psychoactive substance-induced anxiety can be caused as an inescapable effect of the drug itself, by a lack of experience with the substance or its intensity, as an intensification of a pre-existing state of mind, or by the experience of negative hallucinations. The focus of anticipated danger can be internally or externally derived.

Anxiety is often accompanied by other coinciding effects such as depression and irritability. It is most commonly induced under the influence of moderate dosages of hallucinogenic compounds, such as cannabinoids,[4] psychedelics,[5] dissociatives, and deliriants.[6] However, it can also occur during the withdrawal symptoms of GABAergic depressants[7] and during stimulant comedowns.[8]


If you have anxiety, you may want to read the anxiety suppression effect. Additionally, if the anxiety is significantly impacting well-being for a prolonged time period, it is highly recommended to seek out therapeutic medical attention and/or a support group.

Analysis

Fear is not anxiety.[2][3][9][10][11][12] Fear is the response to an immediate threat, whereas anxiety is a set of behaviours attempting to mitigate a perceived future threat. Anxiety disorders are an atypical learning of maladaptive behaviours. While there is substantial evidence indicating anxiety disorders involve genetics and early environmental factors, the practice of anxious thoughts and behavioural patterns also further strengthens their associated neural pathways. Ironically, attempting to avoid anxiety-causing behavioural cues protects the anxiety-causing neural pathways from being extinguished.

Fear and anxiety are defensive neural networks involving many functionally distinct hubs.[10][11][12][13] While there is a substantial overlap between fear and anxiety in these defensive networks, they do differ. Typically the amygdala and bed nucleus of the stria terminalis are the focal points for fear and anxiety respectively, but there are significant problems assigning these as the main center. These hubs generate signals to modify the appropriate defensive neural pathways, but they are not centers for eliciting subjective experience. The body's defensive responses appear before the conscious awareness of feeling threatened, when there is no conscious awareness of feeling threatened, and for survival cues such as hunger. Automatic defensive responses are not by necessity conscious feelings, meaning there are different neural pathways involved for anxiety to be a subjective experience.

Due to the sheer breadth of brain systems involved, the influence of intestinal bacteria,[14] and any potential communicative malfunctioning between any these systems, it's not useful to describe anxiety's underlying neuroanatomy outside of a clinician's context. However, there are specific observable tendencies in anxious individuals:[11]

  • Inflated estimates of threat cost and probability
  • Increased threat attention and hypervigilance
  • Impaired recognition of safety cues
  • Behavioural and cognitive avoidance
  • Heightened reactivity to threat uncertainty

Anxiety disorders are the most common class of mental disorder; one third of the population is affected by an anxiety disorder during their lifetime.[15] It's consistently found that the prevalence in women is twice as high as in men. Patients may suffer from their disorder for years to decades, but it does not mean that it is permanent. There is a high overlap among slightly differing classifications of anxiety disorders, and between anxiety disorders with other mental disorders. It is important to remember that the presence of anxiety is a normal defense mechanism. Anxiety becomes an anxiety disorder when it significantly impacts functional well-being for prolonged periods of time.
