To the Editor: In their study of neuropsychological outcomes of Army personnel after deployment to the Iraq war, Dr Vasterling and colleagues1 describe compromised attention span and memory, increased confusion, and tension. These symptoms can also be associated with grieving.2 The authors did not report on the soldiers' exposure and grief reaction to death as an associated factor. Sudden and unexpected death has been associated with persistent grief reactions.3 The research literature is sparse with regard to neuropsychological symptoms and grieving among soldiers, and further studies should examine this relationship.
