Which of the following best describes excoriation disorder?

A. Severe temper outbursts. Disruptive Mood Dysregulation Disorder (DMDD) is characterized by frequent, severe temper outbursts that are out of proportion to the situation. These outbursts can be verbal or physical and occur at least three times per week, persisting for one year or more.

B. Struggle to regulate emotions. Individuals with DMDD have difficulty managing emotions, particularly anger and frustration. This emotional dysregulation leads to persistent mood instability, which interferes with daily functioning at home, school, and in social settings.

C. Hyperactivity. Hyperactivity is not a core symptom of DMDD but is more commonly associated with Attention-Deficit/Hyperactivity Disorder (ADHD). While some children with DMDD may also have ADHD, DMDD primarily involves severe mood disturbances rather than impulsivity or excessive movement.

D. Chronic irritability. Persistent irritability is a hallmark of DMDD, with children and adolescents experiencing near-constant irritability between temper outbursts. Unlike episodic mood disorders like bipolar disorder, DMDD symptoms are chronic and ongoing without distinct mood episodes.

A. Gabapentin is an anticonvulsant and neuropathic pain medication that has no role in treating enuresis. It works by modulating calcium channels and is primarily used for seizures, neuropathic pain, and restless leg syndrome.

B. Laxatives. While constipation can contribute to enuresis by exerting pressure on the bladder, laxatives do not directly treat bedwetting. Instead, addressing constipation may help reduce nocturnal enuresis in some cases.

C. Desmopressin (DDAVP) is the first-line pharmacologic treatment for enuresis. It is a synthetic analog of antidiuretic hormone (ADH, vasopressin) that reduces night-time urine production, making it effective for nocturnal enuresis (bedwetting) in children.

D. SSRIs. Selective serotonin reuptake inhibitors (SSRIs) are used for depression, anxiety, and OCD but have no primary role in enuresis treatment. In some cases, they may actually cause urinary retention or incontinence as a side effect rather than improving enuresis.
