History

Characteristics and symptoms

Arachnophobia is classified as a specific phobia in the general category of anxiety disorders in the Diagnostic and Statistical Manual of Mental Disorders-5 (2013; DSM-5). Fear of spiders is considered a phobia when it becomes an irrational, persistent mental preoccupation and when it interferes with daily functioning and social activities. Arachnophobia can prevent individuals from taking part in outdoor activities, such as hiking, owing to the chance of encountering a spider. The fear is present even though the affected individual may recognize that only a small percentage of the more than 46,000 species of spiders in the world have bites that are dangerous to humans.

Persons with arachnophobia typically experience disruptive physical and emotional symptoms, particularly anxiety about seeing or being near spiders, which cause significant distress. A phobic reaction to a spider causes hyperactivity in a part of the brain known as the amygdala, which is associated with emotional responses. Symptoms that result may include sweating, shaking, tightness in the chest, rapid heartbeat and breathing, a feeling of choking, and trouble breathing. Other symptoms may include chills, flushed skin, upset stomach, dry mouth, dizziness, and lightheadedness. An individual may scream, cry, freeze, run, or cling to another person upon seeing a spider.

Suspected causes and triggers

Individuals can develop arachnophobia at any point in life; however, similar to other phobias, it often develops in childhood or adolescence. Potential causes include a past traumatic experience with a spider or a child’s exposure to a parent or other family member affected by arachnophobia. In addition, a family history of anxiety disorders may contribute to the development of arachnophobia, and in some instances there may be an underlying genetic component, in which a specific gene mutation increases the risk of developing arachnophobia.

An arachnophobic reaction may be triggered by seeing a spider or a spiderweb, either in person or in a photograph or video. Talking or thinking about spiders or anticipating an upcoming situation in which spiders may be encountered can also trigger symptoms; in the latter case, symptoms often become more intense in the lead-up to the event. Persons with arachnophobia also often cannot stop thinking about spiders, causing difficulty concentrating or even functioning; thoughts of spiders may keep them from sleeping.

Treatment

Treatment for arachnophobia often includes cognitive behavior therapy (CBT), which helps individuals manage phobias by teaching them to recognize and change their thought patterns. CBT also teaches coping skills. In exposure therapy for arachnophobia, patients are gradually exposed to spiders as a way of helping individuals deal with their fear. Exposure therapy usually begins with small steps, such as talking about spiders. Affected individuals may then look at pictures of spiders, experience virtual reality simulations of spiders, and then view real spiders.

In more severe cases medication may be prescribed to help an individual manage anxiety. Medications may include antianxiety drugs, antidepressants, or beta-blockers. Other treatment options include relaxation and breathing exercises, mindfulness, progressive muscle relaxation, meditation, and support groups.
