The spread of various types of addictions is an actual problem in society. In modern world, filled with various stressors, adults and especially teenagers often fall victim to substance use or other addictions. As a result, addictive patients develop symptoms such as: unmotivated aggression and psychosis associated with craving for drug use; in later stages - anhedonia, depression, suicide attempts, as well as a number of serious illnesses. Thus, the development of drug addiction can lead to irreversible consequences for the psychological and physical health of both addicted people and their environment. Despite the differences in the mechanism of action of substance use or other addictions, such as gambling or even video games, numerous experimental and clinical data show that the neurochemical mechanisms underlying the formation of various types of addictions are almost the same and primary involving changes in the mesolimbic dopamine system. This review highlights the internal neurochemical mechanisms underlying the formation of various types of addictions and modern approaches to treatment.
