It has also been observed that the incidence of fire-setting is more common in juvenile and teenage boys than girls of the same age. Intermittent explosive disorder
Intermittent explosive disorder or IED is a clinical condition of experiencing recurrent aggressive episodes that are out of proportion of any given stressor. Earlier studies reported a prevalence rate between 1–2% in a clinical setting, however a study done by Coccaro and colleagues in 2004 had reported about 11.1% lifetime prevalence and 3.2% one month prevalence in a sample of a moderate number of individuals (n=253). Based on the study, Coccaro and colleagues estimated the prevalence of IED in 1.4 million individuals in the US and 10 million with lifetime IED. Kleptomania
Kleptomania is characterized by an impulsive urge to steal purely for the sake of gratification. In the U.S. the presence of kleptomania is unknown but has been estimated at 6 per 1000 individuals. Kleptomania is also thought to be the cause of 5% of annual shoplifting in the U.S. If true, 100,000 arrests are made in the U.S. annually due to kleptomaniac behavior. Signs and symptoms
The signs and symptoms of impulse-control disorders vary based on the age of the persons with them, the actual type of impulse-control that they are struggling with, the environment in which they are living, and whether they are male or female. Co-morbidity
Complications of late Parkinsons disease may include a range of impulse-control disorders, including eating, buying, compulsive gambling, sexual behavior, and related behaviors (punding, hobbyism and walkabout).
However, research conducted in the early 1990s in the United States gave prevalence estimates between 5–6% in the U.S. population, with male cases being higher than female. Internet addiction
The disorder of Internet addiction has only recently been taken into consideration and has been added as a form of ICD. It is characterized by excessive and damaging usage of Internet with increased amount of time spent chatting, web surfing, gambling, shopping or consuming pornography. Excessive and problematic Internet use has been reported across all age, social, economic, and educational ranges. Although initially thought to occur mostly in males, increasing rates have been also observed in females. However, no epidemiological study has been conducted yet to understand its prevalence. Compulsive shopping
Compulsive shopping or buying is characterized by a frequent irresistible urge to shop even if the purchases are not needed or cannot be afforded. The prevalence of compulsive buying in the U.S. has been estimated to be 2–8% of the general adult population, with 80–95% of these cases being females. The onset is believed to occur in late teens or early twenties and the disorder is considered to be generally chronic. Pyromania
Pyromania is characterized by impulsive and repetitive urges to deliberately start fires. Because of its nature, the number of studies performed for fire-setting are understandably limited. However, studies done on children and adolescents with pyromania have reported its prevalence to be between 2.4 and 3.5% in the United States.
