Impulsivity is a complex phenomenon that eludes a single universal definition and has both behavioral and cognitive manifestations. Most current definitions of impulsivity describe it as a tendency to engage in ill-considered behavior that is difficult to postpone. The action is taken so quickly that it is impossible to assess its consequences.
Impulsive behavior can occur as a dominant symptom in many mental illnesses and disorders, especially in bipolar disorder. Another large group of illnesses in which impulsivity plays a significant role are disorders associated with loss of impulse control. However, it is worth emphasizing that impulsivity can also occur in people without mental disorders as a personality trait. It can also be a temporary, transient state, occurring secondary to factors such as severe stress.
People characterized by high impulsivity are often at increased risk of developing. For example, addiction to psychoactive substances or bipolar disorder in the future. It is worth noting that the use of psychoactive substances, through their effect on the central nervous system (CNS), especially the frontal lobes, can cause impulsive disorders, which often manifest themselves as disinhibition and increased impulsivity. The biological basis of impulsivity is still not fully understood. However, the role of the balance of the serotonin and noradrenergic systems is emphasized as key.
