Psychiatric distress is substantially prevalent among elderly individuals, particularly in the primary care and institutional settings, where most older persons receive mental health care. Barriers to care from providers include negative attitudes and stigmatization and poor recognition by general health care professionals. When psychiatric disorders are recognized, the intensity and duration of treatment provided is generally below standards for adequacy. Further research can determine the impact of patient, caregiver, and provider factors on treatment provision and on patient adherence to treatment. Assessment of factors influencing the treatment process are needed to ensure that treatments provided in the real world approximate the efficacy established in controlled clinical trials.
