Many individuals who experience repetitive skin picking often wonder about its potential connection to Attention-Deficit/Hyperactivity Disorder (ADHD). This article explores the nature of skin picking, its recognized association with ADHD, and other related factors.
Understanding Excoriation Disorder (Skin Picking)
Excoriation disorder, also known as dermatillomania, involves recurrent picking at one’s own skin, leading to significant distress or impairment in daily life. Individuals may pick at healthy skin, minor irregularities like pimples or calluses, or even scabs and wounds. This behavior is classified as a body-focused repetitive behavior (BFRB) and can occur in brief episodes or sustained periods, sometimes lasting several hours a day.
The disorder is considered chronic, with periods of varying intensity, and typically begins during adolescence. It affects an estimated 1.4% to 5.4% of American adults, with women more frequently affected than men. Although its exact cause is not fully understood, genetic factors and differences in brain structures that control habit formation may play a role.
The Overlap: Skin Picking and ADHD
Skin picking disorder is not a direct diagnostic criterion for ADHD, but a high rate of co-occurrence exists between the two conditions. Research indicates individuals with ADHD may have an increased likelihood of developing skin picking behaviors. For instance, studies have found that up to 30% of people with ADHD engage in repetitive skin picking.
While skin picking is frequently observed in those with ADHD, it does not function as a unique marker for diagnosis. It is a behavior that often accompanies ADHD, highlighting a shared vulnerability or underlying mechanisms. A 2012 study in the Journal of Psychiatric Research noted a significant comorbidity between skin picking disorder and ADHD in adults, and a 2013 study in the Journal of Obsessive-Compulsive and Related Disorders found college students with ADHD were more likely to report skin picking symptoms.
Potential Explanations for the Connection
Several hypothesized mechanisms explain why skin picking might be more common among individuals with ADHD. One explanation involves self-regulation and fidgeting, where skin picking can serve as a form of self-stimulation or a way to cope with restlessness or under-stimulation. This aligns with the sensory-seeking tendencies often observed in ADHD, providing a tactile outlet for excess energy or a means to regulate overwhelming sensory input.
Impulsivity, a core characteristic of ADHD, also contributes to the onset and continuation of picking behaviors. Individuals with ADHD may struggle with inhibitory control, making it difficult to resist the urge to pick once it arises, often engaging in the behavior without full awareness. This difficulty in stopping can turn occasional picking into a persistent pattern, particularly during moments of boredom or stress.
Links to dopamine pathways and the brain’s reward system are suggested. People with ADHD often have differences in dopamine processing, and picking might provide a momentary sense of relief or a temporary increase in dopamine levels, creating a brief, reinforcing pleasure. Skin picking can also serve as a coping mechanism to manage anxiety, boredom, or emotional discomfort commonly experienced by individuals with ADHD.
Other Conditions Associated with Skin Picking
Skin picking is not exclusive to ADHD and can co-occur with or be intensified by several other mental health conditions. It is classified as a condition within the obsessive-compulsive and related disorders spectrum in the DSM-5. Common co-occurring disorders include Obsessive-Compulsive Disorder (OCD).
Anxiety disorders and depression are also frequently associated with skin picking, as the behavior may serve as a coping mechanism to alleviate distress or negative emotions. Other body-focused repetitive behaviors (BFRBs), such as trichotillomania (hair pulling) and onychophagia (nail biting), often co-occur with excoriation disorder.
When to Seek Professional Guidance
It is appropriate to seek professional help if skin picking causes significant distress, leads to noticeable skin damage, or interferes with daily life and relationships. This includes situations where the skin is frequently irritated, sore, or marked by open wounds, or if there is persistent bleeding, bruising, or scarring. Chronic damage can increase the risk of infections, which may require medical treatment.
Experiencing feelings of shame, guilt, or embarrassment about the behavior, or finding it impossible to control despite repeated attempts to stop, are also strong indicators for seeking support. A healthcare professional, such as a general practitioner or a mental health specialist, can provide an accurate diagnosis and discuss appropriate treatment options for both skin picking and any underlying conditions like ADHD or anxiety. Effective management often involves therapeutic interventions and, in some cases, medication.
