[Lithium treatment for affective disorders in old age]. / Lithiumtherapie zur Behandlung affektiver Störungen im höheren Lebensalter.

BACKGROUND: Lithium is considered the gold standard for the treatment of bipolar affective disorder for the prevention of recurrence of manic and depressive episodes and for augmentation treatment in unipolar severe depressive episodes. The indications for treatment with lithium do not differ for older or younger patients. Nevertheless, there are a number of aspects to be considered with respect to drug safety in the group of old patients. OBJECTIVE: The aim was to give an overview of the current literature on lithium treatment in old age and from this to derive recommendations for action. MATERIAL AND METHODS: A selective literature review on lithium treatment in old age was conducted to answer questions on drug safety, monitoring (particularly with respect to comorbidities) and potential alternatives to lithium. RESULTS AND DISCUSSION: Lithium is an effective and, if used correctly, safe drug also in old people; however, with respect to somatic comorbidities that increase with age, special caution is required when using lithium in order to prevent nephropathy and intoxication.

Development and implementation of quality indicators in a group of nine psychiatric hospitals.

Quality indicators (QI) are becoming increasingly important in mental healthcare in Germany. QI can be used for various purposes, such as for creating transparency as well as for benchmarking between hospitals. QI themselves are subject to high quality standards. The aim of this report is to describe the development and implementation of QI in a group of psychiatric hospitals. Since 2015, the LVR hospital group has developed and gradually implemented QI for the purposes of quality measurement, quality assurance and internal benchmarking in its nine psychiatric hospitals in a comprehensive, multidisciplinary, scientifically accompanied process. The full LVR-QI set, consisting of eight structure-, twelve process- and four outcome indicators as well as one patient satisfaction questionnaire, was implemented by 2019. In order to create high documentation quality and acceptance by clinicians, various implementation and dissemination strategies were used, such as written documentation manuals, staff training as well as regular face-to-face communication between the LVR hospitals, the LVR Institute for Health Services Research as the central coordinating body and the headquarters of the LVR hospital group. The QI led to a quality-oriented dialogue within and between the LVR hospitals.

Training cognition in older male prisoners: lessons learned from a feasibility study.

With increasing numbers of older prisoners, effective strategies for preventing and treating age-associated diseases, such as cognitive disorders, are needed. As pharmacological therapies are limited, non-pharmacological interventions are increasingly recognized as potential treatment strategies. One approach is cognitive training (CT). However, no study has investigated CT in the prison setting. Thus, this one-arm feasibility trial aims to analyze the feasibility of (i) the study protocol and (ii) the implementation of multimodal CT for older prisoners. Eighteen older male prisoners from two specific divisions for older prisoner participated in 12 weekly CT sessions using the NEUROvitalis program. The feasibility analysis included recruitment, dropout, and CT participation rates, and motivation for and satisfaction with CT (using 6-point Likert-scales). The study protocol demonstrated sufficient feasibility with high recruitment rates between 46 and 50%. Therefore, the CT implementation was successful: Only one prisoner ceased participation; all others completed the CT sessions (i.e., attended > 75% of the sessions). Prisoners reported high CT motivation and satisfaction, and would recommend CT. This is the first study to demonstrate CT feasibility in older prisoners. Although more research is needed, these results are a starting point for expanding services to include cognitively enhancing activities for older prisoners.This one-arm feasibility study was pre-registered in the German Clinical Trials Register (DRKS; ID: DRKS00020227).), Registered 11 Mai 2021 https://drks.de/search/de/trial/DRKS00020227 .

Lithium Therapy in Old Age: Recommendations from a Delphi Survey.

INTRODUCTION: While lithium (Li) has been well established for the treatment of bipolar disorder, geriatric patients require special attention when it comes to issues of drug safety. Declining renal function, amongst other medical conditions, and polypharmacy may pose increased risks. Only a few previous studies have addressed the management of Li in geriatric patients. METHODS: Twenty-four German medical experts on geriatric medicine and Li treatment participated in a Delphi survey, consisting of two rounds of questionnaires and a final formulation of treatment recommendations. Three major issues of Li therapy were outlined: initiation of treatment, monitoring of ongoing therapy, and withdrawal due to medical reasons. Final recommendations were consented to at a threshold of at least 80% expert agreement. RESULTS: Final consensus was achieved on 21 clinical recommendations. The approved recommendations covered aspects of necessary laboratory checks, concomitant medication, and target Li serum concentration in geriatric patients. Concerning the termination of Li therapy, an agreement was reached on the appropriate time span for tapering and on potential alternatives to Li. No consensus was achieved on whether concomitant dementia or frailty should be considered contraindications for Li treatment and the appropriate threshold of the estimated glomerular function rate for withdrawing Li. CONCLUSION: According to the view of German experts, Li may be used in geriatric patients, but it should be monitored carefully. However, the lack of consent in several specific treatment situations underlines the need for research on specific issues of Li therapy.

Suicide Attempt Aftercare in Geriatric Patients: A Pilot Project.

Hospitalized patients after suicide attempts gave informed consent to a postvention project after discharge. A continuous caregiver contacted the subjects monthly by phone for a period of 1 year. In case of significant worsening and reoccurrence of suicidal ideations, immediate re-admission was possible. Ten subjects 65 years and older and hospitalized because of suicide attempts were included. The sample was presumed to be at high risk for repeated suicides because of somatic comorbidities and social isolation. Affective state was monitored using the PHQ-9. At the end, the social situation was assessed using the MILVA inventory. Of 16 patients screened for participation only 10 gave informed consent. Six subjects completed the study per protocol. Three subjects died (one suicide, two deaths by natural causes) and one dropped out for other reasons. At the end of the study, all completers appreciated the continuous guidance. While the affective state remained relatively stable in most subjects during the observed period, activities and social isolation could not be modified. Only one patient was readmitted during the project. Phone contacts proved to be feasible in the follow-up after suicide attempts especially in old age, because of the limited mobility of this vulnerable population.

Cognitive function in patients undergoing cystectomy for bladder cancer - results from a prospective observational study.

Background: Impaired cognitive function of bladder cancer patients plays a role in coping with the kind of urinary diversion and may impact perioperative morbidity. In this study we therefore aimed to assess the prevalence of mild cognitive impairment in patients undergoing radical cystectomy. Secondary objectives included correlation of common cognition tests, assessment of the admitting physician, and perioperative complication rates. Methods: Patients undergoing radical cystectomy for bladder cancer were prospectively screened by neuropsychological tests including cognition tests [DemTect (Dementia Detection test), MMSE (Mini-Mental State Examination), clock drawing test] prior to surgery. Besides, clinical characteristics and perioperative outcomes were documented. Frequency of mild cognitive impairment as assessed by DemTect was correlated with the results of MMSE and clock drawing test, the occurrence of anxiety and depression, the assessment of the admitting physician, and perioperative complication rates as calculated by Spearman rank correlation coefficient. Comparative analysis (parametric and nonparametric) of patient characteristics (nonpathological versus pathological DemTect suggestive of mild cognitive impairment) was performed. Results: A total of 51 patients (80% male, median age 69 years) were analyzed. DemTect was suspicious of mild cognitive impairment in 27% (14/51) of patients, whereas MMSE and clock drawing test showed pathological results only in 10/51 and 6/51 patients, respectively. We found no correlation between mild cognitive impairment and anxiety/depression status. In all, 5/20 patients (25%) with suspicious DemTect results were considered suitable for a continent diversion neobladder by the admitting physician. Suspicious DemTect results were predictive for higher perioperative complication rates (29% versus 5%). Study limitations include small sample size and missing long-term follow-up. Conclusions: Mild cognitive impairment was observed in more than a quarter of radical cystectomy patients prior to surgery. Preoperative assessment should be supplemented by neuropsychological testing such as the DemTect as mild cognitive impairment is often underestimated and associated with significantly higher perioperative complication rates.

[Suicidality in older adults]. / Suizidalität im Alter.

Older people have the highest suicide risk compared to all other age groups. Expressions of no longer wanting to live are also found in a large number of older people. The reasons are usually multifactorial and sometimes go back a long way in the personal biography. Limitations resulting from physical illness, mental disorders and social problems make an important contribution. Doctors are often the contact person, even though many older people avoid direct communication in this respect. It is important to perceive and actively address indirect notes, because suicidality is also changeable in very old age. Suicide prevention includes the multimodal treatment of the physical and mental illness, including the (re)activation of resources; however, it also begins in advance, when differentiated images of old age are communicated at the societal level, social participation of older people is practised and the quality of life is maintained until the end.

Characteristics of antipsychotic drug-induced hypothermia in psychogeriatric inpatients.

OBJECTIVE: Hypothermia is a potentially lethal adverse reaction to typical and atypical antipsychotic drugs (APD). Among predisposing factors are advanced age and comorbid somatic diseases. The aim of this study was to assess the incidence of hypothermia and quantify risk factors. METHOD: Charts of N = 3002 psychogeriatric inpatients were screened for incidence of hypothermia (body core temperature <35.0°C). The frequency of hypothermia was compared between patients treated with versus without APD and, within the sample of APD-treated patients, for (1) specific APD, (2) sex, (3) main diagnosis, and (4) age. RESULTS: N = 54 cases (2.6%) of hypothermia occurred in APD-treated patients and 12 cases (1.3%) in non-APD-treated patients (p = 0.024). In APD-treated patients, only male sex (p = 0.038) and pipamperone were associated with a higher incidence of hypothermia (p = 0.0017). Whereas the main diagnosis delirium showed a trend to significance, age did not correlate with hypothermia. CONCLUSION: Medication with pipamperone was associated with an increased risk of hypothermia. The advanced age of our sample might as well explain the high incidence of hypothermia within our sample and the failure to detect high age as a risk factor due to a ceiling effect.

Inpatient Suicides in Late Life: A Retrospective Analysis of a Hospital Group with Nine Psychiatric Clinics.

OBJECTIVE: Inpatient suicides are rare incidents; however, the impacts of such events on associated families and hospital staff are severe. Therefore, preventive strategies need to focus on risk factors. Clinical management in a hospital setting must integrate the home environment and social life of patients. Nevertheless, home leaves require careful preparation. METHODS: Suicides were reported systematically from all psychiatric departments of the Landschaftsverband Rheinland (an assembly of municipalities) using a structured form during two periods (1995-2004, 2005-2014). From these reports we extracted data on suicide methods and sociodemographic and clinical variables. Only patients 65 years and older were included. RESULTS: From a total of 551 reports on suicides in the period of 1995-2014, 103 patients 65 years and older (60 women, 43 men) died by suicide. In contrast to the general trend in Germany during this period, no decline in overall suicide rates was found. Most patients were treated because of depression (73.8%); schizophrenic psychosis was diagnosed in 11.7%; and dementia was only diagnosed in 1.9%. The most frequent suicide method was hanging (40%). All suicides within the hospital were hangings. The majority of suicides occurred outside the hospital during approved home leaves. Only 7% of suicides occurred when patients left the hospital without permission. Almost half of the patients (n = 44) died by suicide during the first month of treatment. With longer duration of hospitalization, the risk of suicide decreased. There were no significant trends with regard to suicide methods between the two periods. CONCLUSIONS: In the first weeks of hospitalizations the patients are most endangered to die by suicide. Therefore, home leaves need careful consideration.

Association of Cerebrospinal Fluid S100B Protein with Core Biomarkers and Cognitive Deficits in Prodromal and Mild Alzheimer's Disease.

BACKGROUND: Increased expression of the astroglial Ca2+-binding protein S100B has been observed in various neurodegenerative diseases and also seems to play a role in the unfolding of pathophysiological events at early stages of Alzheimer's disease (AD). OBJECTIVE: To examine the association of cerebrospinal fluid (CSF) levels of S100B with 1) established CSF core biomarkers total tau (tau), hyperphosphorylated tau (p-tau), and amyloid ß1-42 (Aß1-42) as well as neuron-specific enolase (NSE) CSF levels and 2) cognition in early AD and mild cognitive impairment (MCI) due to AD (MCI-AD). METHODS: Retrospective study assessing 49 pooled charts of Memory Clinic and inpatients diagnosed with AD (N = 26) and MCI-AD (N = 23) according to the National Institute of Aging and Alzheimer's Disease Association (NIA-AA) criteria. Neuropsychological testing was performed with the Consortium to Establish a Registry for AD (CERAD)-Plus battery. RESULTS: CSF levels of S100B correlated with NSE, but not the other CSF parameters. Stepwise multiple linear regression, adjusted for age, sex, and educational level, revealed that only increased CSF S100B was independently associated with lower CERAD-Plus total and Mini-Mental Status Examination scores together with poorer performance in wordlist learning (delayed recall and overall performance). We found no independent associations with other CSF biomarkers or cognitive domains. CONCLUSION: Our data suggest that CSF S100B may have a diagnostic value particularly at early stages of AD reflecting the significance of neuroinflammatory/astroglial processes. Thus, CSF S100B may complement the established array of available AD biomarkers to improve early stage diagnosis.

Longitudinal progression of posterior cortical atrophy over 11 years: Relationship between lesion topology and clinical deficits.

Posterior cortical atrophy (PCA) is a rare form of dementia primarily characterized by slowly progressing deterioration of visual processing corresponding to atrophy in the posterior parietal and occipital cortices with less prominent memory loss than are usually seen in other forms of dementia such as Alzheimer's Disease (AD). In the present case report, we describe longitudinal data over a period of 11 years regarding clinical and neuropsychological impairments and their relation to the location and extent of cortical changes related to higher order visual processing in a patient with posterior cortical atrophy. In our patient, visual processing deficits concerning space, motion and object perception emerged at the age of 50 and continued to worsen. By the age of 58, while the perception of contrast, color and figure-ground separation appeared undisturbed the patient exhibited pronounced dorsal- and ventral-related visual deficits, which continued to worsen with age. The patient's MRI scans over the course of the disease revealed increasing circumscribed and bilateral atrophy of the parietal and occipital cortices, with a right-sided predominance. The specific localization of cortical atrophy, the slow progression characterized by visual processing deficits and relatively preserved memory were the main criteria for the diagnosis of posterior cortical atrophy. The case report also highlights the importance of an early extensive neurological and neuropsychological evaluation of visual deficits that occur without the presence of ophthalmological disease.

A systematic evaluation of impulsive-aggressive behavior in psychogeriatric inpatients using the staff observation aggression scale-revision (SOAS-R).

BACKGROUND: Impulsive-aggressive behavior is a significant challenge in geriatric psychiatry and requires professional evaluation and management. METHODS: SOAS-R scales (Staff Observation Aggression Scale-Revision) completed by medical staff on three secure psychiatric wards were analyzed during a period of 12 months. Patients were subdivided into the following two diagnostic subgroups: dementia and other diagnoses. RESULTS: A total of 146 aggressive incidents involving 66 patients were reported (8.8% of patients treated during this period, n = 752). Fifty-seven percent of the incidents involved patients with dementia. In 20% of the incidents, no precipitating event could be identified; this was more common in patients without dementia (p = 0.005). The medical condition of the patient was considered the trigger in 55% of the cases. Aggression was directed at nurses in 82% of the cases. Visible injury was reported in 12 cases, 3 of which required medical treatment. Male gender, the presence of previous aggressive incidents, and the evening shift (in the case of dementia patients) were identified as risk factors. CONCLUSIONS: Aggression in dementia is often reactive and seems to be more predictable than if occurring with other diagnoses. Prevention measures such as de-escalations techniques, warning notes in the patient's file with previous aggressive behavior and stepping up for evening shifts are of crucial importance. As nurses were primarily affected, employer support programs, and mental health interventions are proposed to avoid long-term consequences.

Repressive Coping Does Not Contribute to Anosognosia in First-Diagnosis Patients With Alzheimer Disease.

Anosognosia is common in patients with Alzheimer disease (AD) even in early stages. Although neural correlates and the impact of cognitive dysfunctions have been described, possible psychodynamic processes such as a repressive coping style as described in other illnesses, have not been examined. Our study aimed to examine possible psychological influence factors on illness perception embracing a repressive coping style and cognitive functions in AD patients in the diagnostic process. Fifty-four subjects with mild AD diagnosed in our memory clinic were enrolled. Anosognosia was evaluated using a patient-caregiver discrepancy rating. All patients underwent comprehensive neuropsychological testing. In addition, characteristics of a repressive coping style were assessed. In total, 79.6% of our patients showed a lack of awareness at least to some degree. 33.3% of the patients were classified as repressors. Repressors and nonrepressors did not differ in cognition, or the unawareness score. Multivariate regression analysis showed that repressive coping style did not significantly contribute to anosognosia, but that verbal memory and naming ability had a strong influence. Although our data indicate that a high proportion of patients with mild AD show characteristics of repressive coping, this possible defense mechanism had no influence on the awareness of illness-related deficits measured by caregiver patient discrepancy.

Epidemiology, symptoms, and treatment characteristics of hyponatremic psychiatric inpatients.

Hyponatremia is a common phenomenon in psychiatry occurring as an adverse effect to drugs or following polydipsia. We performed a retrospective in-depth analysis of hyponatremia cases in a large unselected population of psychiatric inpatients. During a 3-year period, all cases of hyponatremia were identified among patients admitted to a large psychiatric state and university hospital by the institution's electronic laboratory database. Demographic, treatment-related, and laboratory data were obtained by consecutive chart review, respectively. Hyponatremia occurred in 347 (4.9%) of 7113 cases, of which the majority (78%) displayed only a mild manifestation. Symptoms were recorded in 28.8% of cases, already occurred in mild forms, and comprised gait impairment (45%, including falls), confusion (30%), sedation (26%), and dyspepsia (41%). Age, female sex, nonpsychiatric drug polypharmacy-particularly with thiazides and/or angiotensin-converting enzyme inhibitors-and diagnosis of a mood disorder were associated with more severe hyponatremia, respectively. The proportion of hyponatremic patients treated with venlafaxine, trazodone, carbamazepine, oxcarbazepine, and first-generation antipsychotics, respectively, was significantly higher in the hyponatremia sample than in the normonatremic population. This was, surprisingly, not the case with selective serotonin reuptake inhibitors or any other antidepressant drug class. We found prescription with second-generation antipsychotics to be significantly associated with less severe hyponatremia.Hyponatremia may be mainly attributed to the syndrome of inappropriate antidiuretic hormone secretion, as indicated by decreased serum osmolarity in our sample. Besides old age and female sex, treatment with certain drugs-rather than whole drug classes-carries a substantially increased risk.

Anosognosia and depression in patients with Alzheimer's dementia.

Anosognosia refers to impaired awareness of patients to realize deficits related to a disorder and is a common symptom of dementia. Anosognosia has far-reaching consequences for diagnosis and treatment and is probably associated with unfavorable prognosis. This study examined the relationship between anosognosia and depression in patients with Alzheimer's dementia (AD). Assessment included interviews of patients and their caregivers. Depressive symptoms were evaluated with observer and self-rating instruments: the Geriatric Depression Scale (GDS), and the "mood" subscale of the Nurses Observation Scale for geriatric patients (NOSGER). Anosognosia was evaluated with the Anosognosia Questionnaire for Dementia (AQ-D). For the evaluation of behavioral and neuropsychological symptoms in dementia and the caregiver burden, the neuropsychiatric inventory (NPI) and the Cares of older People in Europe (COPE) Index were administered. A total of 47 patients were enrolled in the study at the department's geriatric psychiatry outpatient clinic. A considerable discrepancy was found between observer- and self-ratings of depressive symptoms. In 74.5% of the participants, caregiver ratings indicated secondary symptoms of depression as opposed to patient ratings. Thus, in AD, anosognosia may affect not only deficits in cognition and everyday functioning but also affective symptoms ("affective anosognosia"). Caregiver rating therefore is particularly important when assessing mood changes in AD patients.

Multielectrode array analysis of cerebrospinal fluid in Alzheimer's disease versus mild cognitive impairment: a potential diagnostic and treatment biomarker.

Pathological cerebrospinal fluid (CSF) alterations like changes in amyloid-ß1-42 and tau protein concentration are typical in Alzheimer's disease (AD). However, it remains unclear, if the composition of known or unknown pathological factors in native CSF has a functional significance in AD. In this pilot study, we used multielectrode array (MEA) neurochips to determine whether CSF of individuals with AD (AD-CSF) may have distinct neurofunctional properties that may distinguish it from that of individuals with mild cognitive impairment (MCI) - a differential diagnosis of high clinical importance. MEAs are neuronal cultures coupled to a multisite electrical recording system with the ability to reflect pharmacological or toxicological alterations on the functional level of whole neuronal networks. Collective rhythmical electrical activity was substantially enhanced after exposure to CSF of cognitively healthy subjects (controls) and of MCI individuals (MCI-CSF) alike. However, this activity increment was significantly reduced when MEAs were exposed to AD-CSF compared to MCI-CSF. Moreover, following AD-CSF exposure, networks showed significantly enhanced burst durations and less synchronous bursting, respectively. Thus, AD-CSF and MCI-CSF could be distinguished by characteristic changes of the network firing pattern on MEAs. When data of MCI individuals and AD patients were pooled, the network suppression correlated significantly with the degree of cognitive decline. The findings of this pilot study may set the stage for a unique and straightforward diagnostic bioassay of AD with particular value in the differential diagnosis to MCI and as a much needed biomarker for clinical trials.
