Coexistent depressive and anxiety disorders in epilepsy and multiple sclerosis: a challenge to neuropsychiatric practice

Abstract

The high rate of co-existent emotional disorders in major neurological disorders, such as epilepsy and multiple sclerosis is challenging. As a rule, this co-existence comprises a more dramatic subjective suffering, a reduced psychological coping, possible negative interferences with somatic treatments and rehabilitations, an impaired quality of life and higher grades of psychosocial disability. It may also lead to an overall increased risk of somatic morbidity and even mortality in the further course of illness. These complex interrelations may be favourably integrated within a biopsychosocal model. Psychological and psychosocial stressors can be appreciated on their own discrete levels, have to be reflected, however, in their neurobiological correlates. Both neurological and emotional disorders frequently share decisive pathogenetic mechanisms, i.e. the underlying process of neurological disease may contribute to major affective problems also in a somato-psychic direction. In addition, mutual interactions of both neurological and psychiatric treatments in their impact on the emotional and neurological risks have to be appreciated.
