Ørbo MC, et al. - The associations between global brain volumes, hippocampal subfield volumes and verbal memory performance were investigated in long-term survivors of out-of-hospital cardiac arrest (OHCA). Researchers noticed that 3 months after resuscitation, both hippocampal volume and cortical volume were smaller in good outcome OHCA survivors in comparison to healthy controls. Smaller cerebral volumes were observed to be associated with poorer memory performance.
