Although impulsive behavior is found in many different forms in the literature, the shortest definition of the concept can be expressed as "the tendency to act without thinking, to act with a sudden, irresistible, irrational desire" (Kırpınar, 2013: 166). Impulsive behavior is mainly seen in young children and obsessive-compulsive or antisocial adults who have not developed adequate defense systems against impulses. Pathological gambling, kleptomania (urge to steal), pyromania, trichotylmania (compulsive behavior in the form of hair pulling), etc. Impulsive behavior is considered as structures that deform the person's quality of life and differ from compulsion behaviors in that they are episodic (Kırpınar, 2013: 166).
19. Impulse control disorders have attracted the attention of scientists since the end of the century, but in parallel with the small number of cases, few objective studies have been conducted on this subject. In this context, they are considered as rare cases both in textbooks and other medical literature and are briefly emphasized (Okay, 2015:833). One of these cases is a rare form of trichotillomania, conceptualized in the literature as "rapunzel syndrome". This syndrome was first described by Vaughan in 1968 and many case reports were made subsequently. This form is explained in the shortest definition as the patient eating his hair impulsively. The first contemporary descriptive studies on impulse control disorders are; It is seen that it emerged in the late 1990s and that the subject started to be studied intensively since then. (Jacobson J. and Jacobson A., 2006: 243)
While the behavioral pattern that emerges due to the increase in the dopaminergic system can be reconciled with its physiological basis, psychosocial differences are likely to be a factor in the structuring of this behavior. If we need to examine it in terms of the principle of parsimony, the simplest explanation is that the increase in neuronal activation in dopamine and serotonin receptors can be seen as the source of impulsivity. Regarding the subject; Neuroscience as a trigger of impulsive behavior, according to data obtained from clinical and cohort studies conducted with people experiencing euphoria. biological axioms can be demonstrated. Research conducted by Michal and Gendel also supports this assumption. Although it seems that the neurobiological aspect of impulsive behavior has not yet been elucidated in relevant research, based on the phenomenon of "intermittent explosive disorder", acceptable evidence from studies conducted for this behavior-based disorder has shown that there is abnormal serotonin metabolism
DISCUSSION
According to OK; He stated that although impulsivity, as a personality trait, is a behavioral pattern that has been known for centuries, it is not possible to say the same for impulse control disorders, which can be described as excessive and uncontrolled expression (Okay, 2015:833). Impulsive behavior is expressed as the transformation of the impulse, which is a deloparization wave transmitted along a nerve or muscle fiber, into an action potential (Budak, 2001:243). The prefrontal and orbitofrontal cortex are involved in the control of suppression, decision-making and response selection processes. The orbitofrontal cortex plays a major role in regulating behavior based on available information about the consequences of one's actions. For this reason, impulsivity is frequently observed in people with frontal lobe damage. Regarding this, it has been stated that the decrease in brain serotonin levels reduces the suppression of behavior. Taking eating disorders as an example, it is a subject that needs research and development as it may be effective in neurobiological factors, learned behaviors and social sanctions.
