Specific Phobia
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 the 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. It can be described as when patients are anxious about a particular situation. It causes a great load of difficulty in life. Patient ...

Anxiety Disorder
Anxiety disorders are a cluster of mental disorders characterized by significant and uncontrollable feelings of anxiety and fear such that a person's social, occupational, and personal function are significantly impaired. Anxiety may cause physical and cognitive symptoms, such as restlessness, irritability, easy fatiguability, 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 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 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) or anxiety symptoms. There ...

Ophidiophobia
Ophidiophobia (or ophiophobia) is a particular type of specific phobia, the irrational fear of snakes. It is sometimes called by a more general term, herpetophobia, fear of reptiles. The word comes from the Greek words "ophis" (), snake, and "phobia" () meaning fear. Research About a third of adult humans are ophidiophobic, making this one of the most commonly reported phobias. In ''The Handbook of the Emotions'' (1993), psychologist Arne Öhman studied pairing an unconditioned stimulus with evolutionarily-relevant fear-response neutral stimuli (snakes and spiders) versus evolutionarily-irrelevant fear-response neutral stimuli (mushrooms, flowers, physical representation of polyhedra, firearms, and electrical outlets) on human subjects and found that ophidiophobia and arachnophobia required only one pairing to develop a conditioned response while mycophobia, anthophobia, phobias of physical representations of polyhedra, firearms, and electrical outlets required multiple pa ...

Avoidant Personality Disorder
Avoidant personality disorder (AvPD) is a Cluster C personality disorder characterized by excessive social anxiety and inhibition, fear of intimacy (despite an intense desire for it), severe feelings of inadequacy and inferiority, and an overreliance on avoidance of feared stimuli (e.g. self-imposed social isolation) as a maladaptive coping method.''Anxious voidant personality disorder' in ICD-10Diagnostic Criteria anClinical descriptions and guidelines. Those affected typically display a pattern of extreme sensitivity to negative evaluation and rejection, a belief that one is socially inept or personally unappealing to others, and avoidance of social interaction despite a strong desire for it. It appears to affect an approximately equal number of men and women. People with AvPD often avoid social interaction for fear of being ridiculed, humiliated, rejected, or disliked. They typically avoid becoming involved with others unless they are certain they will not be rejected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Substance Use Disorder
Substance use disorder (SUD) is the persistent use of drugs (including alcohol) despite substantial harm and adverse consequences as a result of their use. Substance use disorders are characterized by an array of mental/emotional, physical, and behavioral problems such as chronic guilt; an inability to reduce or stop consuming the substance(s) despite repeated attempts; operating vehicles while intoxicated; and physiological withdrawal symptoms. Drug classes that are commonly involved in SUD include: alcohol (alcoholism); cannabis; opioids; stimulants such as nicotine (including tobacco), cocaine and amphetamines; benzodiazepines; barbiturates; and other or unknown substances. In the Diagnostic and Statistical Manual of Mental Disorders 5th edition (2013), also known as DSM-5, the DSM-IV diagnoses of substance abuse and substance dependence were merged into the category of substance use disorders. The severity of substance use disorders can vary widely; in the DSM-5 diagno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agoraphobia
Agoraphobia is a mental and behavioral disorder, specifically an anxiety disorder characterized by symptoms of anxiety in situations where the person perceives their environment to be unsafe with no easy way to escape. These situations can include open spaces, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Differential Diagnosis
In healthcare, a differential diagnosis (abbreviated DDx) is a method of analysis of a patient's history and physical examination to arrive at the correct diagnosis. It involves distinguishing a particular disease or condition from others that present with similar clinical features. Differential diagnostic procedures are used by clinicians to diagnose the specific disease in a patient, or, at least, to consider any imminently life-threatening conditions. Often, each individual option of a possible disease is called a differential diagnosis (e.g., acute bronchitis could be a differential diagnosis in the evaluation of a cough, even if the final diagnosis is common cold). More generally, a differential diagnostic procedure is a systematic diagnostic method used to identify the presence of a disease entity where multiple alternatives are possible. This method may employ algorithms, akin to the process of elimination, or at least a process of obtaining information that shrinks th ...

Traumatophobia
According to the DSM-IV classification of mental disorders, the injury phobia is a specific phobia of blood/injection/injury type. It is an abnormal, pathological fear of having an injury."Oxford Textbook of Psychopathology" by Theodore Millon, Paul H. Blaney, Roger D. Davis (1999) p. 82/ref> Another name for injury phobia is traumatophobia, from Greek τραῦμα (''trauma''), "wound, hurt" and φόβος (''phobos''), "fear". It is associated with BII (Blood-Injury-Injection) Phobia. Sufferers exhibit irrational or excessive anxiety and a desire to avoid specific feared objects and situations, to the point of avoiding potentially life-saving medical procedures. According to one study, it is most common in females. What sets injury phobia apart is that it is when a person is exposed to blood, an injury, or an injection, they begin to experience extreme sensations of terror, such as breathlessness; excessive sweating; dry mouth; feeling sick; shaking; heart palpitations; inabil ...

Hemophobia
Blood phobia (also known as hemophobia or hematophobia in American English and haemophobia or haematophobia in British English) is an extreme irrational fear of blood, a type of specific phobia. Severe cases of this fear can cause physical reactions that are uncommon in most other fears, specifically vasovagal syncope (fainting). Similar reactions can also occur with trypanophobia and traumatophobia. For this reason, these phobias are categorized as blood-injection-injury phobia by the DSM-IV. Some early texts refer to this category as "blood-injury-illness phobia." Causes Blood phobia is often caused by direct or vicarious trauma in childhood. Though some have suggested a possible genetic link, a study of twins suggests that social learning and traumatic events, rather than genetics, is of greater significance.. Blood-injection-injury phobia (BII) affects about 4% of the population in the United States. The inclusion of BII within the category of specific or simple phobias ...

Trypanophobia
Fear of needles, known in medical literature as needle phobia, is the extreme fear of medical procedures involving injections or hypodermic needles. This can lead to avoidance of medical care, including vaccine hesitancy. It is occasionally referred to as '' aichmophobia'', although this term may also refer to a more general fear of sharply pointed objects. Overview and incidence The condition was officially recognized in 1994 in the DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, 4th edition) as a specific phobia of blood-injection-injury type phobia (BII phobia). Phobic level responses to injections cause sufferers to avoid inoculations, blood tests, and in the more severe cases, all medical care. It is estimated that at least 10% of American adults have a fear of needles, and it is likely that the actual number is larger, as the most severe cases are never documented due to the tendency of the sufferer to avoid all medical treatment. The diagnosis criteria fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nyctophobia
Fear of the dark is a common fear or phobia among children and, to a varying degree, adults. A fear of the dark does not always concern darkness itself; it can also be a fear of possible or imagined dangers concealed by darkness. Some degree of fear of the dark is natural, especially as a phase of child development. Most observers report that fear of the dark seldom appears before the age of two years. When fear of the dark reaches a degree that is severe enough to be considered pathological, it is sometimes called scotophobia (from – "darkness"), or lygophobia (from – "twilight"). Some researchers, beginning with Sigmund Freud, consider the fear of the dark to be a manifestation of separation anxiety disorder. An alternate theory was posited in the 1960s, when scientists conducted experiments in a search for molecules responsible for memory. In one experiment, rats, normally nocturnal animals, were conditioned to fear the dark and a substance called "scotophobin" was ...

Claustrophobia
Claustrophobia is the fear of confined spaces. It can be triggered by many situations or stimuli, including elevators, especially when crowded to capacity, windowless rooms, and hotel rooms with closed doors and sealed windows. Even bedrooms with a lock on the outside, small cars, and tight-necked clothing can induce a response in those with claustrophobia. It is typically classified as an anxiety disorder, which often results in panic attacks. The onset of claustrophobia has been attributed to many factors, including a reduction in the size of the amygdala and classical conditioning. One study indicates that 5–10% of the world population is affected by severe claustrophobia, but only a small percentage of these people receive some kind of treatment for the disorder. The term ''claustrophobia'' comes from Latin ' "a shut in place" and Greek ', '' phóbos'', "fear". Signs and symptoms Claustrophobia is classified as a mental and behavioral disorder, specifically an an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gerascophobia
Gerascophobia is an abnormal or incessant fear of growing older or ageing (senescence). Background Gerascophobia is a clinical phobia generally classified under specific phobias or fears of a single specific panic trigger. Gerascophobia may be based on anxieties of being left alone without resources and incapable of caring for oneself due to age-caused disability. Symptoms Some sufferers seek plastic surgery to make them look more youthful, while the main concern of others is a fear of internal, biological long-term damage caused by the aging process. Etymology The term ''gerascophobia'' comes from the Greek γηράσκω, ''gerasko'', "I grow old" and φόβος, ''phobos'', "fear".''Perspectives on Aging'', by Priscilla W. Johnston, 1982, , pp. 239-241 Some authors refer to it as gerontophobia, although this may also refer to the fear of the elderly due to memento mori.
