Neurobiologia del trattamento del PTSD e della depressione maggiore : cosa ci dicono le neuroimmagini

2016 - Franco Angeli

169-177 p.

  • Questo articolo riguarda l'utilizzo delle neuroimmagini come efficace strumento d'indagine per comprendere le basi anatomo funzionali dei processi mentali e presenta una revisione della letteratura scientifica rispetto ad alcuni disturbi (PTSD e depressione maggiore) connessi alla violenza subita e correlati ad alterate interazioni tra strutture cerebrali implicate nel controllo ed elaborazione delle emozioni. Gli studi in breve mostrano come una mancata inibizione della corteccia prefrontale sull'amigdala provochi un'ipereccitabilità delle strutture implicate nella regolazione emotiva, elaborazione e memorizzazione dell'informazione, con impoverimenti anche strutturali in aree corticali e sottocorticali, a vari livelli. Le neuroimmagini sugli effetti delle psicoterapie riscontrano anche, in seguito a trattamenti psicoterapeutici eseguiti con successo e insieme alla scomparsa dei sintomi, una normalizzazione delle strutture partecipanti al medesimo network limbico/emozionale.

  • Neuroimaging is an efficient tool to investigate the anatomical and functional basis of mental processes. A revision of the scientific literature regarding conditions (PTSD and major depression) connected to violence and traumatic experiences is presented, exploring the connection between these syndromes and a modified interaction between cerebral structures implicated in the control and processing of emotions. Research shows how a missing inhibition of the prefrontal cortex on the amygdala leads to hyperexcitability of the structures involved in emotional regulation, elaboration and memorization of information and with impoverishments, some of which structural, in cortical and subcortical areas at multiple levels.
  • Neuroimaging on the effects of psychotherapy show, in successful psychotherapeutic treatments resulting in the disappearance of the symptoms, a normalisation of the structures regarding the same limbic emotional network.
