Post-traumatic stress disorder (PTSD) is a debilitating mental illness triggered by a significant frightful event such as war, natural disaster or violence. In the past, it was associated mainly with veterans, but nowadays, the incidence shows a rising trend, with a percentage of 3.9% of people worldwide who have declared to suffer from PTSD, especially correlated to the COVID-19 pandemic and the increasing war anxiety. The major associated symptoms are hyperarousal, sleep disorders, social anxiety and isolation, conditions that negatively affect the quality of life. The current therapies, cognitive behaviour and pharmacological therapies, focus on reducing symptoms rather than curing the disease.
