Psychogerontology is nowadays an interdisciplinary field of study where gerontology and clinical psychology converge. This is due to the fact that the training of the psychogerontologist contemplates the exhaustive knowledge of the sciences of aging and the theoretical-practical knowledge of the techniques of psychotherapeutic approach visualized from a neuropsychological, cognitive-behavioral or psychoanalytical current.
