People who come to the emergency department with a brain injury are often not admitted, but instead are sent home with advice. A follow-up study of these people found that although they were satisfied with the advice, memory for the specific details (eg. rest, alcohol/drugs, medication, work, sports) was relatively poor. And memory for the advice was worse for people with longer periods of post-traumatic amnesia (PTA). The study's authors recommend that people who come to the hospital with PTA of more than five minutes should be targeted for follow-up or inpatient admission.
