Body-Focused Repetitive Behaviors

Body-Focused Repetitive Behaviors (BFRBs) are defined as motor and cognitive actions repeatedly performed by an individual that carry a risk of causing harm to or discomfort in their own body. These behaviors are often associated with stress, anxiety, distress, or concentration difficulties and can be difficult to control. This condition, extensively studied in psychology and psychiatry, is closely linked to obsessive-compulsive spectrum disorders.

The concept of body-focused repetitive behaviors began to be examined in detail in psychiatry and psychology during the second half of the 20th century. Known in Western literature as "Body-Focused Repetitive Behaviors (BFRBs)," this concept is evaluated within the obsessive-compulsive disorder spectrum but exhibits distinct differences. Conditions such as trichotillomania (hair pulling) and dermatillomania (skin picking) were first described in psychiatric handbooks and subsequently classified as clinical disorders.

Various behaviors fall under the category of BFRBs. The most common include:

1. Nail Biting (Onychophagia): The involuntary chewing or pulling of fingernails triggered by stress or anxiety.
2. Hair Pulling (Trichotillomania): The unconscious, repetitive pulling of hair from the scalp or other body areas such as eyebrows or eyelashes, leading to bald patches.
3. Skin Picking (Dermatillomania): The repetitive picking of skin to the extent of causing new wounds, often targeting blemishes, scars, or healthy skin.
4. Teeth Grinding (Bruxism): The clenching or grinding of teeth, typically occurring during sleep.

Biological, psychological, and environmental factors contribute to the emergence of BFRBs. These behaviors are linked to impulse control mechanisms in the brain and may also be influenced by genetic factors. Imbalances in certain neurotransmitters, particularly fluctuations in serotonin levels, can contribute to the persistence of these behaviors.

Treatment of BFRBs varies depending on the severity of symptoms and underlying causes. The most common treatment approaches include:

• Cognitive Behavioral Therapy (CBT): Helps strengthen impulse control mechanisms.
• Habit Reversal Training (HRT): Encourages the development of an alternative behavior to replace the problematic one.
• Pharmacotherapy: Antidepressants and anxiolytic medications may be effective in some cases.
