A recent meta-analysis of randomized trials revealed that antiepileptic drugs (AEDs) as a class increase the risk of suicidal thoughts and behavior. We conducted an observational study with data from the United Kingdom General Practice Research Database to investigate if an increase in risk for different groups of AEDs is also evident in clinical practice. ⋯ Newer AEDs with a rather high frequency of depressive symptoms in clinical trials may also increase the risk of self-harm or suicidal behavior in clinical practice. For the most commonly used other groups of AEDs, no increase in risk was observed.

The Vietnam Head Injury Study (VHIS) is a prospective, longitudinal follow-up of 1,221 Vietnam War veterans with mostly penetrating head injuries (PHIs). The high prevalence (45%-53%) of posttraumatic epilepsy (PTE) in this unique cohort makes it valuable for study. ⋯ Patients with PHI carry a high risk of PTE decades after their injury, and so require long-term medical follow-up. Lesion location, lesion size, and lesion type were predictors of PTE.

The present retrospective cohort study compares the long-term functional outcome, improvement or deterioration, of patients considered in a vegetative state (VS) or a minimally conscious state (MCS) 1 year after coma onset, then yearly for up to 5 years. ⋯ In contrast to patients in VS, a third of patients in MCS improved more than 1 year after coma onset. This emphasizes the need to define reliable boundaries between VS and MCS using repeated clinical evaluations and all imaging and neurophysiologic tools available today.
