Swiss doctors are highlighting an increased risk of PTSD in patients with severe COVID-19 after treating a man who developed false memories about his care, including delusions of abuse. 

The 67-year-old was intubated for 13 days after being admitted to ICU with severe acute respiratory distress syndrome, a bacterial infection and septic shock. 

His hospitalisation was further complicated by acute renal failure requiring temporary dialysis, the University Hospitals of Geneva doctors said. 

When he was finally extubated and transferred to the medical ward, he was extremely emotional, anxious and had false memories and delusions about his hospitalisation.
