Providers who treat stroke sufferers need to do a better job of screening them for depression, a new study suggests.

In a study of 1,450 ischemic stroke survivors and 397 transient ischemic attack (TIA) survivors, investigators found that 18% of stroke patients and over 14% of TIA survivors experienced depression three months following their initial hospitalization. Nearly 70% of all the stroke and TIA participants with persistent depression were not being treated with antidepressants at follow-ups.

The study was published March 29 in the journal Stroke.
