L’émission d’Arte sur la plasticité du cerveau a abordé 4 maladies neurologiques :
– TOC ou Troubles Obsessionnels Compulsifs ;
– conséquences d’un AVC (accident Vasculaire Cérébral) et nouveau traitement pour améliorer les capacités (orales) à communiquer diminuées par un AVC ;
– nouveau médicament associé à une thérapie contre le SSPT ou syndrome de stress post-traumatique (PTSD, Post-Traumatic Stress Disorder) ;
– schizophrénie : les nouveaux traitements (jeu vidéo) de remédiation cognitive contre les symptômes de a schizophrénie.
SSPT = syndrome de stress post-traumatique
PTSD = Post-Traumatic Stress Disorder (syndrôme de stress post-traumatique)
la plasticité du cerveau le rend vulnérable après un traumatisme (accident, guerre, viol, vision d’un suicidé ou d’un mort…)
ancien médicament qui est utilisé depuis peu contre les SSPT : le Propranolol
Propranolol is currently being investigated as a potential treatment for post-traumatic stress disorder.[11][12][13][14] Propranolol works to inhibit the actions of norepinephrine, a neurotransmitter that enhances memory consolidation. Studies have shown that individuals given propranolol immediately after a traumatic experience show less severe symptoms of PTSD compared to their respective control groups that did not receive the drug (Vaiva et al., 2003). Propranolol reduces the effects of nightmare-related cardiac activity by keeping sinus rhythm low during nightmares, as a higher pulse and increased adrenaline are associated with severe nightmares. However, results remain inconclusive as to the success of propranolol in treatment of PTSD, including nightmares experienced by those with PTSD. There are also many ethical and legal questions surrounding the use of Propranolol-based medications for use as a « memory dampener, » including: altering (memory-recalled) evidence during an investigation, modifying behavioral response to past (albeit traumatic) experiences, the regulation of these drugs, and others.[15]
