A specific phobia is a generic term for any kind of anxiety disorder that amounts to an unreasonable or irrational fear related to exposure to specific objects or situations. As a result, the affected persons tend to actively avoid direct contact with the objects or situations and, in severe cases, any mention or depiction of them.
The fear or anxiety may be triggered both by the presence and the anticipation of the specific object or situation. A person who encounters that of which they are phobic will often show signs of fear or express discomfort. In some cases it can result in a panic attack. In most cases of adults, this kind of phobia is consciously recognized by the person; still, anxiety and avoidance are difficult to control and may significantly impair person's functioning and even physical health.
