DEAR DOCTOR K: Last year, a truck ran a red light, totaled my car and nearly totaled me. I spent several weeks in the hospital. Since then my body has healed, but I'm not myself. I'm very irritable, easily angered and sleeping poorly. A friend says I have PTSD, but I thought that occurred to people -- soldiers, for instance -- exposed to repeated threats.
DEAR READER: Your friend is astute. Post-traumatic stress disorder -- PTSD -- is a condition in which distressing symptoms occur after a major trauma. While the media often talk about PTSD in soldiers who have seen active combat, you don't have to be in battle to get PTSD. A single horrible event, like a bad auto accident, can surely do it.
