Una ricerca condotta su topi traumatizzati, ad esempio dopo l'incontro con un gatto, ha dimostrato che una cura a base di mirtilli, già molto apprezzati come antiossidanti, può aiutare a superare i disturbi.
I roditori nutriti per un mese con una dieta a base di queste bacche hanno infatti sormontato senza troppi danni la violenta emozione causata dal manifestarsi del loro incubo peggiore. Il consumo del piccolo frutto fa aumentare il livello di serotonina, molecola importante come regolatore dell'umore, esercitando effetti simili a quelli di un antidepressivo.
Benché preliminare, lo studio, condotto presso l'Università della Louisiana, è interessante perché indica un'alternativa all'uso di farmaci nel trattamento di malesseri psicologici dovuti alla tensione nervosa.
