A Case Report of Home-Based Cognitive-Behavioural Treatment for Late-Onset Post-Traumatic Stress Disorder, Triggered by Mask-Wearing in the Context of the COVID-19 Pandemic.

A small but clinically significant number of people experience delayed-onset Post-traumatic stress disorder (PTSD); symptoms of trauma years after the events which are now being re-experienced. The following case report describes the use of the cognitive-behavioural treatment for PTSD with a woman experiencing flashbacks to domestic abuse endured more than 20 years ago. Mask-wearing mandated as a result of the COVID-19 pandemic triggered non-contextualised memories of life-threatening physical violence by an abuser who covered his face.
