Summary

Whole-body cryotherapy (WBC), which consists of a short exposure to very cold and dry air in special ‘cryo-chambers’, is believed to reduce inflammation and musculoskeletal pain as well as improve athletes’ recovery. This is the case of a 63-year-old male, who presented with transient global amnesia (TGA) after undertaking a WBC session. TGA is a clinical syndrome characterised by a sudden onset of anterograde amnesia, sometimes coupled with a retrograde component, lasting up to 24 hours without other neurological deficits. Even though the patient completely recovered, as expected, in 24 hours, this case highlights that WBC is potentially not as risk free as thought to be initially. To conclude, before WBC can be medically recommended, well-conducted studies investigating the possible adverse events are required.
