Concept
Phobie spécifique
Résumé
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. Patients have a lot of distress or interference when functioning in their daily life. Unreasonable or irrational fears get in the way of daily routines, work, and relationships due to the effort that a patient makes to avoid the terrifying feelings associated with the fear.
Females are twice as likely to be diagnosed than males with a specific phobia (although this can depend on the stimulus).
Children and adolescents who are diagnosed with a specific phobia are at an increased risk for additional psychopathology later in life.
Fear, discomfort or anxiety may be triggered both by the presence and the anticipation of the specific object or situation. The main behavioral sign of a specific phobia is avoidance. The fear or anxiety associated with specific phobia can also manifest in physical symptoms such as an increased heart rate, shortness of breath, muscle tension, sweating, or a desire to escape the situation.
The exact cause of specific phobias is not known. The mechanisms for development of specific phobias can be distinguished between innate (genetic and neurobiological) factors, and learned factors.
