[Geriatric syndromes, multimorbidity and geriatric psychiatry; an integrated perspective]. / Geriatrische syndromen, multimorbiditeit en ouderenpsychiatrie; een geïntegreerd perspectief.

BACKGROUND: The prevalence of geriatric syndromes, frailty and multimorbidity increases in older age, with a negative impact on health outcomes. Little is known on these problems in older adults with psychiatric disorders. AIM: To evaluate the prevalence of geriatric syndromes and multimorbidity in older adults with psychiatric disorders and their impact on treatment outcomes. METHOD: We conducted a pilot study and a case-control study on older adults with medically insufficiently explained symptoms, a prospective cohort study in older adults, acutely admitted to psychiatric wards and a systematic review to evaluate whether geriatric syndromes were considered in RCTs on depression treatment. RESULTS: Unexplained symptoms were often accompanied by frailty, multimorbidity and psychiatric disorders. Older adults who were acutely admitted to psychiatric wards had a high level of multimorbidity, about half of them were frail, and a third undernourished. Frailty and multimorbidity were independent predictors for not being discharged to their own home. Frailty also strongly predicted the 5-year mortality rate. Geriatric syndromes were hardly considered in study design or as secondary outcome in treatment studies on depression in older adults. CONCLUSION: Overall, geriatric problems are highly prevalent among older adults with psychiatric disorders and have a relevant prognostic impact. The complexity of older psychiatric patients is probably best addressed by interdisciplinary, integrated diagnostic and treatment trajectories.

Psychiatric characteristics of older persons with medically unexplained symptoms: A comparison with older patients suffering from medically explained symptoms.

BACKGROUND: Empirical studies on the clinical characteristics of older persons with medically unexplained symptoms are limited to uncontrolled pilot studies. Therefore, we aim to examine the psychiatric characteristics of older patients with medically unexplained symptoms (MUS) compared to older patients with medically explained symptoms (MES), also across healthcare settings. METHODS: A case-control study including 118 older patients with MUS and 154 older patients with MES. To include patients with various developmental and severity stages, patients with MUS were recruited in the community (n = 12), primary care (n = 77), and specialized healthcare (n = 29). Psychopathology was assessed according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria (Mini-International Neuropsychiatric Interview) and by dimensional measures (e.g., psychological distress, hypochondriasis, and depressive symptoms). RESULTS: A total of 69/118 (58.5%) patients with MUS met the criteria for a somatoform disorder according to DSM-IV-TR criteria, with the highest proportion among patients recruited in specialized healthcare settings (p = 0.008). Patients with MUS had a higher level of psychological distress and hypochondriasis compared to patients with MES. Although psychiatric disorders (beyond somatoform disorders) were more frequently found among patients with MUS compared to patients with MES (42.4 vs. 24.8%, p = 0.008), this difference disappeared when adjusted for age, sex, and level of education (odds ratio = 1.7 [95% confidence interval: 1.0-3.0], p = 0.070). CONCLUSIONS: Although psychological distress is significantly higher among older patients with MUS compared to those with MES, psychiatric comorbidity rates hardly differ between both patient groups. Therefore, treatment of MUS in later life should primarily focus on reducing psychological distress, irrespective of the healthcare setting patients are treated in.

[Medically unexplained symptoms in older adults: a combination of physical, psychiatric and psychological factors]. / Onverklaarde lichamelijke klachten bij ouderen: samenspel van lichamelijke, psychiatrische en psychologische factoren.

3 women aged 75, 75 and 65 years, respectively, were referred to an outpatient clinic for medically unexplained symptoms (MUS). These cases illustrate the heterogeneity and complexity of MUS in elderly patients, which requires broad, multidisciplinary clinical examination by a geriatrician, psychiatrist and psychologist. The first patient presented with persistent pain in the lower back and legs. Examination revealed a spinal stenosis, which was treated surgically; symptoms subsequently resolved. The second patient had chronic abdominal pain and constipation in combination with depression. She was diagnosed with a severe depressive disorder. After adequate drug treatment, her mood improved and the somatic symptoms disappeared. The third patient complained of headache and feared that she may have a brain tumour. There was no somatic diagnosis. She underwent cognitive behavioural group therapy, which substantially improved her functioning. These cases illustrate the diversity and complexity of MUS in elderly patients and underscore the diagnostic appropriateness of the biopsychosocial paradigm. A specialised multidisciplinary examination ensures accurate diagnosis and cognitive behavioural therapy.
