There are very little data on the burden among caregivers of older adults with severe mental diseases. We aimed to assess the perceived burden among caregivers of family members with schizophrenia spectrum and bipolar disorders. A cross-sectional study was carried out with 52 older patients with schizophrenia spectrum and bipolar disorders and their family caregivers. Caregivers were assessed with the medical outcome survey short form (SF-36), the Zarit Burden Interview (ZBI) and the Depression Anxiety and Stress scales (DASS-21).
