Among relatives of patients with epilepsy, the prevalence of depression is greater among those who believe they have an increased risk of epilepsy because they may have inherited an epilepsy-related mutation. Shawn T. Sorge and his colleagues reached that conclusion after surveying 417 individuals in 104 families in which 4 persons per family had the disease on average. On the other hand, individuals with epilepsy seemed less troubled by the diagnosis: The likelihood of having depression was not related to any potential epilepsy-related mutation among persons who already have epilepsy.
