Anxiety disorder in the context of "Autism spectrum"

Agoraphobia is an anxiety disorder characterized by symptoms of anxiety in situations where the person perceives their environment to be unsafe with no way to escape. These situations can include public transit, shopping centers, crowds and queues, or simply being outside their home on their own. Being in these situations may result in a panic attack. Those affected will go to great lengths to avoid these situations. In severe cases, people may become completely unable to leave their homes.

Agoraphobia is believed to be due to a combination of genetic and environmental factors. The condition often runs in families, and stressful or traumatic events such as the death of a parent or being attacked may be a trigger. In the DSM-5, agoraphobia is classified as a phobia along with specific phobias and social phobia. Other conditions that can produce similar symptoms include separation anxiety, post-traumatic stress disorder, and major depressive disorder. The diagnosis of agoraphobia has been shown to be comorbid with depression, substance abuse, and suicidal ideation.Without treatment, it is uncommon for agoraphobia to resolve. Treatment is typically with a type of counselling called cognitive behavioral therapy (CBT). CBT results in resolution for about half of people. In some instances, those with a diagnosis of agoraphobia have reported taking benzodiazepines and antipsychotics. Agoraphobia affects about 1.7% of adults. Women are affected about twice as often as men. The condition is rare in children, often begins in adolescence or early adulthood, and becomes more common at age 65 or above.

Fear is an unpleasant subjective emotional state arising in response to perceived dangers or threats and which, when experienced, is typically associated with physiological and psychological changes. These changes frequently lead to behavioral reactions such as fight-or-flight responses or, in extreme cases, immobilization (freeze response). Unlike most (perhaps all) other animals, humans can experience fear in response to a present or anticipated stimulus and to imagined events.

Most internalizing psychopathologies (depression, anxiety, suicidal thoughts and behaviors, and so forth) are associated with and maintained by dysfunctional, anxious, or fearful feelings and thoughts. Phobias, or exaggerated and often disabling fears, are usually similarly dysfunctional.

Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized by a group of symptoms that commonly include abdominal pain, abdominal bloating, and changes in the consistency of bowel movements. These symptoms may occur over a long time, sometimes for years. IBS can negatively affect quality of life and may result in missed school or work or reduced productivity at work. Disorders such as anxiety, major depression, and myalgic encephalomyelitis/chronic fatigue syndrome are common among people with IBS, sometimes developing due to the condition.

The cause of IBS is not known but multiple factors have been proposed to lead to the condition. Theories include combinations of "gut–brain axis" problems, alterations in gut motility, visceral hypersensitivity, infections including small intestinal bacterial overgrowth, neurotransmitters, genetic factors, and food sensitivity. Onset may be triggered by a stressful life event, or an intestinal infection. In the latter case, it is called post-infectious irritable bowel syndrome.

Disgust (Middle French: desgouster, from Latin gustus, 'taste') is an emotional response of rejection or revulsion to something potentially contagious or something considered offensive, distasteful or unpleasant. In The Expression of the Emotions in Man and Animals, Charles Darwin wrote that disgust is a sensation that refers to something revolting. Disgust is experienced primarily in relation to the sense of taste (either perceived or imagined), and secondarily to anything which causes a similar feeling by sense of smell, touch, or vision. Musically sensitive people may even be disgusted by the cacophony of inharmonious sounds. Research has continually proven a relationship between disgust and anxiety disorders such as arachnophobia, blood-injection-injury type phobias, and contamination fear related obsessive–compulsive disorder (also known as OCD).

Disgust is one of the basic emotions of Robert Plutchik's theory of emotions, and has been studied extensively by Paul Rozin. It invokes a characteristic facial expression, one of Paul Ekman's six universal facial expressions of emotion. Unlike the emotions of fear, anger, and sadness, disgust is associated with a decrease in heart rate (for body-envelope violations) and proto-nausea of the stomach (for bodily effluvia).

A psychosocial hazard or work stressor is any occupational hazard related to the way work is designed, organized and managed, as well as the economic and social contexts of work. Unlike the other three categories of occupational hazard (chemical, biological, and physical), they do not arise from a physical substance, object, or hazardous energy.

Psychosocial hazards affect the psychological and physical well-being of workers, including their ability to participate in a work environment among other people. They cause not only psychiatric and psychological outcomes such as occupational burnout, anxiety disorders, and depression, but they can also cause physical injury or illness such as cardiovascular disease or musculoskeletal injury. Psychosocial risks are linked to the organization of work as well as workplace violence and are recognized internationally as major challenges to occupational safety and health as well as productivity.

A phobia is an anxiety disorder, defined by an irrational, unrealistic, persistent and excessive fear of an object or situation. Phobias typically result in a rapid onset of fear and are usually present for more than six months. Those affected go to great lengths to avoid the situation or object, to a degree greater than the actual danger posed. If the object or situation cannot be avoided, they experience significant distress. Other symptoms can include fainting, which may occur in blood or injury phobia, and panic attacks, often found in agoraphobia and emetophobia. Around 75% of those with phobias have multiple phobias.

Phobias can be divided into specific phobias, social anxiety disorder, and agoraphobia. Specific phobias are further divided to include certain animals, natural environment, blood or injury, and particular situations. The most common are fear of spiders, fear of snakes, and fear of heights. Specific phobias may be caused by a negative experience with the object or situation in early childhood to early adulthood. Social phobia is when a person fears a situation due to worries about others judging them. Agoraphobia is a fear of a situation due to perceived difficulty or inability to escape.

Specific phobia is an anxiety disorder, characterized by an extreme, unreasonable, and irrational fear associated with a specific object, situation, or concept which poses little or no actual danger. Specific phobia can lead to avoidance of the object or situation, persistence of the fear, and significant distress or problems functioning associated with the fear. A phobia can be a fear of anything.

Although fears are common and normal, a phobia is an extreme type of fear where great lengths are taken to avoid being exposed to the particular danger. Phobias are considered the most common psychiatric disorder, affecting about 10% of the population in the US, according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), (among children, 5%; among teens, 16%). About 75% of patients have more than one specific phobia.

Social anxiety disorder (SAD), also known as social phobia, is an anxiety disorder characterized by sentiments of fear and anxiety in social situations, causing considerable distress and impairing ability to function in at least some aspects of daily life. These fears can be triggered by perceived or actual scrutiny from others. Individuals with social anxiety disorder fear negative evaluations from other people.

Physical symptoms often include excessive blushing, excessive sweating, trembling, palpitations, rapid heartbeat, muscle tension, shortness of breath, and nausea. Panic attacks can also occur under intense fear and discomfort. Some affected individuals may use alcohol or other drugs to reduce fears and inhibitions at social events. It is common for those with social phobia to self-medicate in this fashion, especially if they are undiagnosed, untreated, or both; this can lead to alcohol use disorder, eating disorders, or other kinds of substance use disorders. According to ICD-10 guidelines, the main diagnostic criteria of social phobia are fear of being the focus of attention, or fear of behaving in a way that will be embarrassing or humiliating, avoidance and anxiety symptoms. Standardized rating scales can be used to screen for social anxiety disorder and measure the severity of anxiety.

Separation Anxiety Disorder (SAD) is an anxiety disorder in which an individual experiences excessive anxiety regarding separation from home and/or from people to whom the individual has a strong emotional attachment (e.g., a parent, caregiver, significant other, or siblings). Separation anxiety is a natural part of the developmental process. It is most common in infants and little children, typically between the ages of six months to three years, although it may pathologically manifest itself in older children, adolescents and adults. Unlike SAD (indicated by excessive anxiety), normal separation anxiety indicates healthy advancements in a child's cognitive maturation and should not be considered a developing behavioral problem.

According to the American Psychiatric Association (APA), Separation Anxiety Disorder is an excessive display of fear and distress when faced with situations of separation from the home and/or from a specific attachment figure. The anxiety that is expressed is categorized as being atypical of the expected developmental level and age. The severity of the symptoms ranges from anticipatory uneasiness to full-blown anxiety about separation.
