Obsessive-Compulsive Disorder (OCD) is a chronic neurological and behavioral condition characterized by intrusive, distressing thoughts (obsessions) that trigger intense anxiety. To alleviate this distress, individuals feel driven to perform repetitive behaviors or mental rituals (compulsions), creating an exhausting cycle that severely disrupts daily life.

Body Dysmorphic Disorder (BDD) is a distressing psychiatric condition characterized by an intense, obsessive preoccupation with perceived flaws or defects in one's physical appearance that are unnoticeable or appear minor to others. This distressing fixation drives individuals to perform exhausting, repetitive rituals—such as excessive grooming, constant mirror checking, or seeking reassurance—that severely impact their emotional well-being and daily functioning.

Trichotillomania is a neurological and body-focused repetitive behavior disorder characterized by an irresistible, recurrent urge to pull out one's own hair, most commonly from the scalp, eyebrows, or eyelashes. Despite repeated attempts to stop, the behavior is often driven by a mounting internal tension that is temporarily relieved by pulling, creating a distressing cycle that can lead to significant hair loss and emotional distress.

Excoriation disorder, commonly known as skin-picking disorder, is a body-focused repetitive behavior characterized by the chronic, compulsive urge to pick at one's own skin, leading to physical tissue damage and severe emotional distress. Despite repeated, exhausting attempts to stop or decrease the behavior, individuals feel driven by a mounting internal tension that is only temporarily relieved by picking, significantly impacting their daily social and professional life.

Tic disorders are neurological conditions characterized by sudden, rapid, and recurrent movements or vocalizations—known as tics—that are involuntary and repetitive. Often preceded by an uncomfortable premonitory urge that is temporarily relieved by executing the tic, these symptoms typically fluctuate in severity and can significantly interfere with an individual’s social, academic, and daily functioning.

Hoarding disorder is a persistent psychiatric condition characterized by chronic difficulty discarding or parting with possessions, regardless of their actual material or monetary value. This behavior is driven by a perceived need to save the items and intense distress associated with discarding them, ultimately leading to severe clutter that congests living areas, compromises safety, and significantly impairs daily functioning.
