had a history of psychological disturbance and/or lost
consciousness. Not being able to recall receiving infor-
mation about expected symptoms and how best to deal
with them may result in greater long-term reporting of
PCS. The study has implications for clinical practice.
Screening for history of psychological disturbance and
careful documentation of LOC in the ED are important
indicators of risk of potential persistent symptoms that
could be implemented. Provision of information about
potential PCS with suggested coping strategies is an
inexpensive intervention that may minimize PCS.
