[Diseases of the schizophrenia spectrum disorder in old age : Diagnostic and therapeutic challenges].

BACKGROUND

The number of people with diseases of the schizophrenia spectrum in old age will increase significantly in the coming years. In the literature the topics of schizophrenia and delusional disorders in older and old people are inadequately represented.

AIM: This article gives an overview of the most important diagnostic and differential diagnostic characteristics. Another important aspect is the pharmacological and non-pharmacological treatment options in old age.

MATERIAL AND

METHODS

The S3 guidelines of the German Association for Psychiatry, Psychotherapy and Psychosomatics (DGPPN) from 2006, the guidelines of the World Federation of Societies of Biological Psychiatry (WFSBP) from 2012, 2013, 2015 and the consensus statement of the Austrian Association for Neuro-Psychopharmacology and Biological Psychiatry (ÖGPB) from 2016 formed the basic literature for this review. In addition, a targeted search in the databases PubMed, PubPsych and Cochrane Library as well as in German Journals, such as DerNervenarzt, Neuropsychiatrie, Psychiatrische Praxis and Zeitschrift für Gerontologie und Geriatrie concerning the keywords schizophrenia, delusional disorder, diagnostics, therapy and older people was carried out.

RESULTS

Besides aspects on epidemiology, clinical manifestation, diagnostics, differential diagnostics and course of the illness, pharmacological and non-pharmacological treatment options are presented.

CONCLUSION/DISCUSSION: In clinical practice a clear diagnostic assignment is often a challenge in older and very old people with psychotic symptoms, The necessary pharmacological treatment is available but is limited by tolerability, comorbidities and polypharmacy. Non-pharmacological treatment options have hardly been investigated.
