Alcol e adolescenza, quali sono gli effetti nella crescita?

Pinterest Google+

L’assunzione frequente di alcolici durante l’adolescenza modifica la forma dei neuroni.

A confermarlo è stato uno studio pubblicato sulla rivista “Alcoholism: Clinical and Experimental Research”, che descrive l’impatto, sulle cellule cerebrali e sul comportamento, dell’esposizione all’alcol durante l’adolescenza.

I ricercatori della Research Society on Alcoholism, in Texas, hanno condotto due test su topi maschi adulti dopo l’esposizione all’alcool durante l’adolescenza o l’età adulta: hanno testato gli animali sul consumo di alcol e la sensibilità all’intossicazione e hanno misurato i cambiamenti nella densità e nella struttura delle terminazioni dei neuroni presenti in alcune zone della corteccia e dell’amigdala.

E’ emerso che l’esposizione cronica all’alcool durante l’adolescenza ha prodotto alterazioni significative e persistenti nella densità spinale dendritica dei neuroni presenti della corteccia infralimbica e nelle regioni basilaterali dell’amigdala.

Tali cambiamenti erano inoltre accompagnati da alterazioni comportamentali, con conseguenze durature e potenzialmente dannose.
