What are Specific Phobias?
Causes
Specific phobias often emerge in childhood and tend to run in families, which suggests there may be a heritable genetic component. However, they can develop at any age after a traumatic or distressing encounter with the feared stimulus. Classical conditioning may play a role in which the stimulus becomes associated with a frightening event and elicits a fear response on subsequent exposures. Imbalances in certain neurotransmitters like serotonin have also been observed in individuals with phobias.
Symptoms
When confronted with their phobic stimulus, individuals exhibit an immediate anxious response, including a racing heart, rapid breathing, trembling, and feelings of unreality or detachment. They may attempt to avoid or flee from the trigger to ease their anxiety. Generalized psychological distress, nausea, dizziness, and panic attacks can also occur. The fear, anxiety, and avoidance behaviours cause significant distress and impair the person’s quality of life.
Types
Common specific phobias include:
Hematophobia – fear of blood
Ophidiophobia – fear of snakes
Trypanophobia – fear of needles or injections
Treatments
1. Specific phobias are highly treatable using techniques like exposure therapy, which gradually exposes the patient to the feared stimulus in a safe, controlled setting.
2. Cognitive-behavioural therapy helps patients change negative thought patterns associated with their phobia.
3. Anti-anxiety medications are sometimes used as an adjunct treatment.
4. Desensitization and modelling can also teach the person to face and overcome their fear triggers over time.
With proper treatment, most patients see a lasting elimination of phobic symptoms and avoidance behaviours.
