I didn’t know it at the time, and didn’t talk much about it [definitely not publicly], but recently realised I had PTSD from mid-late teens to mid 20s, related to various traumatic events. 1/ ted.com/talks/joelle_r…
Symptoms: Nightly nightmares (esp. family members dying). Anxiety. Depression. Extreme sweating. Rashes. Constantly on edge (fight/flight/freeze, literally freezing at a thought). Visions. Tics, mostly repressed [exhausting]. #PTSD 2/

A little story about prospective memory. Last week at #HSJPatientSafety I talked a bit about research on prospective memory, in the context of Kathryn Walton's account of her terrifying experience of being accidentally paralysed following a forgotten cannula. 1/
It appeared that there was an intention to remove the cannula, which had the substance in the dead space, but this was forgotten. Research I did in ATC years ago showed prospective memory forgetting to be the dominant kind. dl.dropboxusercontent.com/u/4953549/Pape… 2/
