Psikostimülan İlaçların Gelişen Beyin Üzerindeki Etkileri.

Although psychostimulants have been used for the treatment of attention deficit hyperactivity disorder for approximately 70 years, little is known about the long term effects of these drugs on developing brain. The observable effects of psychostimulants are influenced by the timing of exposure, the age of examination after drug exposure and sex. Preclinical studies point out that chronic psychostimulant exposure before adolescence cause reverse sensitization or tolerance and this leads to reduction in stimulant effectiveness in adolesecence and adulthood. Preclinical studies show the potential long term effects of psychostimulants. But it is necessary to investigate the relationship between preclinical effects and clinical practice. A developmental approach is needed to understand the impact of pediatric medications on the brain that includes assessment at multiple ages to completely characterize the long term effects of these medications. The aim of this paper is to review the effects of psychostimulants on developing brain. [ABSTRACT FROM AUTHOR]
