Neuropsychological functioning, age, and medication adherence in bipolar disorder

Neurocognitive correlates of metabolic dysregulation in individuals with mood disorders: a systematic review and meta-analysis

Individuals with mood disorders are predisposed to metabolic dysfunction, while those with metabolic dysregulation such as diabetes and obesity experience more severe depressive symptoms. Both metabolic dysfunction and mood disorders are independently associated with cognitive deficits. Therefore, given their close association, this study aimed to explore the association between metabolic dysfunction in individuals with mood disorders in relation to cognitive outcomes. A comprehensive search comprised of these three domains was carried out; a random-effects meta-analysis pooling mean cognitive outcomes was conducted (PROSPERO ID: CRD42022295765). Sixty-three studies were included in this review; 26 were synthesized in a quantitative meta-analysis. Comorbid metabolic dysregulation was associated with significantly lower global cognition among individuals with mood disorders. These trends were significant within each mood disorder subgroup, including major depressive disorder, bipolar disorder, and self-report depression/depressive symptoms. Type 2 diabetes was associated with the lowest cognitive performance in individuals with mood disorders, followed by peripheral insulin resistance, body mass index ⩾25 kg/m2, and metabolic syndrome. Significant reduction in scores was also observed among individual cognitive domains (in descending order) of working memory, attention, executive function, processing speed, verbal memory, and visual memory. These findings demonstrate the detrimental effects of comorbid metabolic dysfunction in individuals with mood disorders. Further research is required to understand the underlying mechanisms connecting mood disorders, metabolism, and cognition.

Direct and Indirect Predictors of Medication Adherence With Bipolar Disorder: Path Analysis

BACKGROUND

Despite the efficacy of treatment and severity of symptoms, medication adherence by many with bipolar disorder (BD) is variable at best. This poses a significant challenge for BD care management.

OBJECTIVE

For this study, we set out to identify psychosocial and psychiatric predictors of medication adherence with BD.

METHODS

Using microtargeted social media advertising, we recruited an international sample of young and older adults with BD living in North America (Canada and the United States), Western Europe (eg, United Kingdom and Ireland), Australia and New Zealand (N=92). On average, participants were 55.35 (SD 9.65; range 22-73) years of age, had been diagnosed with BD 14.25 (SD 11.14; range 1-46) years ago, and were currently prescribed 2.40 (SD 1.28; range 0-6) psychotropic medications. Participants completed questionnaires online including the Morisky Medication Adherence Scale.

RESULTS

Medication adherence did not significantly differ across BD subtypes, country of residence, or prescription of lithium versus other mood stabilizers (eg, anticonvulsants). Path analyses indicate that alcohol misuse and subjective or perceived cognitive failures are direct predictors of medication adherence. BD symptoms, psychological well-being, and the number of comorbid psychiatric conditions emerged as indirect predictors of medication adherence via perceived cognitive failures.

CONCLUSIONS

Alcohol misuse did not predict perceived cognitive failures. Nor did age predict medication adherence or cognitive failures. This is noteworthy given the 51-year age range of participants. That is, persons in their 20s with BD reported similar levels of medication adherence and perceived cognitive failures as those in their 60s. This suggests that perceived cognitive loss is a facet of adult life with BD, in contrast to the assumption that accelerated cognitive aging with BD begins in midlife.

Cyclothymic Temperament, Physical Neglect, and Earlier Age of Onset Predict Poor Medication Adherence in Patients With Bipolar Disorder

ABSTRACT

Individual-level risk factors may predict poor medication adherence (PMA) in bipolar disorder (BD). This study aimed to evaluate the association between affective temperament, childhood trauma, age of first onset, and PMA in patients with BD in China. A total of 168 patients completed the eight-item Morisky Medication Adherence Scale; the Short Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire; and the Childhood Trauma Questionnaire-Short Form. Scores were then compared between PMA and non-PMA groups. Binary logistic regression showed that age of first onset was negatively correlated with PMA ( β = -0.106, p = 0.002), whereas physical neglect and cyclothymic temperament were positively correlated with PMA ( β = 0.143, p = 0.029; β = 0.19, p = 0.001, respectively). These findings indicate that cyclothymic temperament, physical neglect, and earlier onset are predictors of PMA in patients with BD and that such patients may require further attention to improve medical compliance.

Neuropsychological aspects of bipolar disorder

Bipolar disorder (BD) is a chronic condition with serious consequences on the health and functionality of patients who suffer from it, with a high heritability and segregation, and aprevalence of between 1% and 2%. Neuropsychological deficits have been implicated as a very important issue related to BD prognosis, so a review was conducted of these deficits, the related factors and their functional consequences. It has been determined that the presence of neuropsychological deficits can vary in patients with BD according to their mood state, with a great influence of depressive symptoms on the cognitive variability of patients with respect to the general population and differences with respect to patients in the manic phase. In euthymic patients, the most affected cognitive domains are those of memory, attention, and executive function, associated with a more severe disease, sociodemographic vulnerability factors, and stable over time. A relationship has been found between poor cognitive performance, especially executive dysfunction, and objective functional deficit. Furthermore, cognitive differences have been outlined between BD and other serious mental illnesses that are described in this review.

Direct medical cost of bipolar disorder: Insights from the FACE-BD longitudinal cohort

BACKGROUND

Bipolar disorder (BD) is a severe chronic psychiatric disorder affecting 0.5 to 1% of the population worldwide. To date, most studies have estimated the cost of BD via information sourced from insurance claims with limited information on clinical characteristics and course of BD. The aims of this study are (i) to estimate the direct healthcare cost associated with BD and to identify contributing factors and (ii) to study the evolution of cost during a two-year follow-up period.

METHOD

We analyzed a sample of 1116 individuals with BD included in the Advanced Centers of Expertise in Bipolar Disorder cohort. We estimated the direct healthcare cost per year and per patient, and we identified the clinical features of patients with BD associated with higher direct healthcare costs. In a subsample of patients followed up for two years centers of expertise for BD, we studied the evolution of direct healthcare cost.

RESULTS

The average cost of bipolar disorder was € 6910 per year and per patient. Clinical features of BD, sociodemographic characteristics, and associated addiction were associated with higher direct healthcare costs. In the subsample of patients followed-up for two years, direct healthcare cost dropped by more than 50%, strongly suggesting the beneficial effect of specialized care organization.

LIMITATION

We did not estimate indirect healthcare and intangible costs.

CONCLUSION

Our study investigates the cost of BD and its evolution in a deeply phenotyped longitudinal sample. Cost-utility and cost-effectiveness analyses are required to inform resource allocation decisions and to promote innovative healthcare organizations.

Finalization and Validation of Questionnaire and Algorithm of SPUR, a New Adherence Profiling Tool

Purpose

The SPUR (Social, Psychological, Usage and Rational) Adherence Profiling Tool is a recently developed adaptive instrument for assessing key patient-level drivers for non-adherence. This study describes the SPUR questionnaire's finalization and psychometric evaluation.

Patients and Methods

Data were collected through an online survey among patients with type 2 diabetes included by general practitioners and diabetologists in France. The survey included four questionnaires, SPUR and three validated adherence measures: BMQ, MARS and ACCEPT. Item-level analysis and a partial credit model (PCM) were performed to refine the response option coding of SPUR items. The final item selection of SPUR was defined using a PCM and a principal component analysis (PCA). Construct validity, concurrent validity and known-groups validity were assessed on the final SPUR questionnaire.

Results

A total of 245 patients (55% men, mean age of 63 years) completed the survey remotely and were included in this analysis. Refining response option coding allowed a better discrimination of patients on the latent trait. After item selection, a short, an intermediate, and a long form composed the final SPUR questionnaire. The short form will be used to screen patients for risk and then the other forms will allow the collection of further information to refine the risk assessment and decide the best levers for action. Results obtained were supportive of the construct validity of the forms. Their concurrent validity was demonstrated: moderate to high significant correlations were obtained with BMQ, MARS and ACCEPT scores. Their known-groups validity were shown with a logical pattern of higher scores obtained for patients considered non-adherent and significant differences between the scores obtained for patients considered adherent versus non-adherent.

Conclusion

SPUR is a valid tool to evaluate the risk of non-adherence of patients, allowing effective intervention by providing insights into the respective individual reasons for lack of adherence.

Efficacy and Safety of Lumateperone for Major Depressive Episodes Associated With Bipolar I or Bipolar II Disorder: A Phase 3 Randomized Placebo-Controlled Trial

OBJECTIVE

In a phase 3 randomized double-blind placebo-controlled study, the authors investigated the efficacy and safety of 42 mg/day of lumateperone in patients with bipolar I or bipolar II disorder experiencing a major depressive episode.

METHODS

Patients 18-75 years old with a clinical diagnosis of bipolar I or bipolar II disorder and experiencing a major depressive episode were eligible for the study. Patients were randomized in a 1:1 ratio to receive 42 mg/day of lumateperone (N=188) or placebo (N=189), administered orally once daily in the evening for 6 weeks. The primary and key secondary efficacy endpoints were change from baseline to day 43 in score on the Montgomery-Åsberg Depression Rating Scale (MADRS) and total score on the Clinical Global Impressions Scale-Bipolar Version severity scale (CGI-BP-S), respectively. Safety assessments included treatment-emergent adverse events, laboratory parameters, vital signs, extrapyramidal symptoms, and suicidality.

RESULTS

At day 43, lumateperone treatment was associated with significantly greater improvement from baseline in MADRS score compared with placebo (least squares mean difference compared with placebo, -4.6 points; effect size=-0.56) and CGI-BP-S total score (least squares mean difference compared with placebo, -0.9; effect size=-0.46). Significant MADRS superiority for lumateperone over placebo was observed both in patients with bipolar I and bipolar II disorders. Somnolence and nausea were the only treatment-emergent adverse events that occurred with lumateperone at a clinically meaningful greater rate than placebo. The incidence of extrapyramidal symptom-related treatment-emergent adverse events was low and similar to that for placebo. Minimal changes were observed in weight, vital signs, or metabolic or endocrine assessments.

CONCLUSIONS

Lumateperone at 42 mg/day significantly improved depression symptoms and was generally well tolerated in patients with major depressive episodes associated with both bipolar I and bipolar II disorders.

Relation of medication adherence to cognitive functions in egyptian patients with bipolar I disorder

Nonadherence to medication regimens is frequently reported in bipolar I disorder (BDI) patients. However, little is known about the relationship between cognitive functions and adherence in BDI. To establish possible associations between medication adherence and cognitive function in patients with BDI. A total of 110 inpatients with BDI were subjected to the Structured Clinical Interview for DSM-IV Axis I Disorder, Morisky 8-Item Medication Adherence Scale, Young Mania Rating Scale, Wechsler Adult Intelligence Scale-Revised, Wechsler memory scale (WMS) and Wisconsin card sorting test (WCST). Patients were assessed on admission and followed up 6 months after discharge. Six months after discharge, (58.2%) of patients were nonadherent to their medications. The nonadherent group were younger males with less years of education, with lower mean scores in information orientation and visual memory backward domains of WMS and lower mean scores in perseveration responses, perseveration errors and learning to learn domains of WCST. In logistic regression analysis, younger age and impaired information orientation domain of WMS were putative predictors of nonadherence. Episodic memory and younger age were the strongest patients' related factors associated with nonadherence to medication. These results suggest that rehabilitation of specific cognitive skills may improve adherence in BDI.

Mapping modifiable determinants of medication adherence in bipolar disorder (BD) to the theoretical domains framework (TDF): a systematic review

BACKGROUND

Around 40% of people with bipolar disorder (BD) are non-adherent to medication leading to relapse, hospitalisation and increased suicide risk. Limited progress in addressing non-adherence may be partly attributable to insufficient understanding of the modifiable determinants of adherence that require targeting in interventions. We synthesised the modifiable determinants of adherence in BD and map them to the theoretical domains framework (TDF).

METHOD

We searched CINAHL, Cochrane Library, Embase, LILACS, Medline, PsychINFO and PubMed until February 2020. We included studies reporting modifiable determinants of adherence in BD. Two reviewers independently screened studies, assessed quality, extracted modifiable determinants and mapped them to TDF.

RESULTS

We included 57 studies involving 32 894 participants. Determinants reported by patients spanned 11 of the 14 TDF domains compared to six domains represented by clinician/researcher. The TDF domains most commonly represented (% and example) in studies were: 'Environmental context and resources' (63%, e.g. experiencing side effects), 'Beliefs about consequences' (63%, e.g. beliefs about medication effects), 'Knowledge' (40%, e.g. knowledge about disorder), 'Social influences' (33%, e.g. support from family/clinicians), 'Memory, attention and decision processes' (33%, e.g. forgetfulness), 'Emotion' (21%, e.g. fear of addiction) and 'Intentions' (21%, e.g. wanting alternative treatment). 'Intentions', 'Memory, attention and decision processes' and 'Emotion' domains were only reported by patients but not clinicians.

CONCLUSIONS

Clinicians may be underappreciating the full range of modifiable determinants of adherence and thus not providing adherence support reflective of patients' needs. Reporting of modifiable determinants in behavioural terms facilitates developing theory-based interventions to address non-adherence in BD.

Real-World Treatment Patterns and Adherence to Oral Medication Among Patients with Bipolar Disorders: A Retrospective, Observational Study Using a Healthcare Claims Database

PURPOSE

This study aimed to describe real-world treatment patterns and medication adherence among patients with bipolar disorder (BD) in Japan.

PATIENTS AND METHODS

Adult patients with a BD diagnosis were identified between July 2013 and February 2018, using an employment-based health insurance claims database from the JMDC Inc. Treatment patterns of target drugs (mood stabilizers, antipsychotics) and adherence (measured by the proportion of days covered [PDC]) were assessed during the first- through third-year follow-up. Adherence was also assessed for patient subgroups.

RESULTS

The analyzed population included 13,788 patients with BD. They were mostly prescribed sodium valproate, lithium, or aripiprazole (range: 21.1-27.4%) across 3 years of follow-up, whereas lamotrigine was prescribed to 11.2-12.8% of patients. Benzodiazepines (70-87%) and antidepressants (52-71%) were commonly prescribed during all three follow-up periods. The mean PDC among all patients with BD was 0.51 during the first and increased to 0.61 during the third year. The mean PDC was 0.42 (first year) in patients aged <30 years and 0.49 in those aged 30-40 years. The PDC was 0.44-0.61 (depending on the drug class) in those who were prescribed a single-class target drug and 0.68-0.83 in those prescribed two drug classes concomitantly.

CONCLUSION

This study documented generally low medication adherence among patients with BD, and those at young age. These patients may require more attention.

End-of-Life Care Among Patients With Bipolar Disorder and Cancer: A Nationwide Cohort Study

OBJECTIVE

This study aimed to describe end-of-life (EOL) care in individuals with bipolar disorder (BD) who died of cancer compared with mentally healthy individuals.

METHODS

This was a nationwide cohort study of all adult individuals who died of cancer in hospitals in France between 2013 and 2016. Outcomes were compared between individuals with BD and mentally healthy individuals in the last month of life including palliative care and high-intensity EOL care (chemotherapy, artificial nutrition, and other interventions). A subanalysis explored differences between patients with BD and patients with schizophrenia.

RESULTS

The study included 2015 individuals with BD and 222,477 mentally healthy controls. Compared with the controls, individuals with BD died 5 years earlier, more often had comorbidities and thoracic cancer, and had fewer metastases, but did not have shorter delays from cancer diagnosis to death. After matching and adjustment for covariates, individuals with BD more often received palliative care in the last 3 days of life (25% versus 13%, p < .001) and less high-intensity care (e.g., chemotherapy 12% versus 15%, p = .004), but more artificial nutrition (6% versus 4.6%, p = .003). Compared with the schizophrenia comparison group, chemotherapy was received more by individuals with BD in the last 14 days of life (12.5% for BD versus 9.4%, p < .001).

CONCLUSIONS

Individuals with BD were more likely to receive palliative care and less likely to receive high-intensity EOL care, except for artificial nutrition. These results may not be specific to BD, as no difference was found between patients with BD and schizophrenia except for chemotherapy.

Psycho-demographic and clinical predictors of medication adherence in patients with bipolar I disorder in a university hospital in Egypt

BACKGROUND

Poor adherence to treatment is one of the main challenges to symptom control and preventing recurrence in bipolar disorder (BD). Numerous studies have established an association between patients' poor adherence and an increased risk of recurrence, relapse of the symptoms and admission to hospital.

AIM

To study the socio-demographic and clinical factors associated with medication nonadherence in patients with BD who were admitted to the hospital.

SETTING

The study was conducted at the Institute of Psychiatry, Ain Shams University.

METHODS

A 1-year longitudinal prospective study of 110 patients, aged 18-60 years, with BD-I. Young Mania Rating Scale, Clinical Global Impression, Global Assessment of Functioning, Sheehan Disability Scale and Insight and Treatment Attitude Questionnaire were applied before and 6 months after discharge. Adherence was measured using the Morisky 8-Item Medication Adherence Scale. Sociodemographic data and level of functioning were studied in relation to adherence.

RESULTS

Higher adherence was noticed in female, married and older patients and those with a higher level of education. However, low adherence was more common in male, non-married and less educated patients. Follow-up after 6 months revealed that the high adherence group scored the lowest in terms of disability. Meanwhile, the low adherence group scored the highest scores in disability.

CONCLUSION

Several socio-demographic and clinical variables were found to be associated with a low adherence rate to the prescribed medication in patients with BD-I. Age and impaired insight were found to be significant predictive factors for non-adherence.

Pharmacotherapy for the peripartum management of bipolar disorder

Introduction: The peripartum period in bipolar disorder (BD) patients is associated with high risk of relapse. Relapse during this period may affect fetal and child development. The consequences of psychotropic medication during pregnancy are also a major concern. The extent to which mood stabilizers may potentially affect the embryogenesis or the child development varies from high (e.g. valproate) to less clear and more debated (e.g. lithium). Areas covered: This review describes the current state of evidence with respect to the impact of recommended pharmacological interventions for BD during the peripartum period. It compares recent international treatment guidelines for the management of BD during the peripartum period. Last, this review presents a summary of key recommendations for BD women of childbearing age, for BD women during pregnancy and postpartum period from the international guidelines. Expert opinion: Management of the pharmacological treatment for BD patients during the perinatal period is challenging. Although treatment guidelines may be of significant help, high heterogeneity exists across them. Shared decision-making represents a useful patient-centered approach during the perinatal period. Large cohort studies are needed to better identify risk associated to treatment discontinuation or treatment exposure.

The Patient-Reported Experience Measure for Improving qUality of care in Mental health (PREMIUM) project in France: study protocol for the development and implementation strategy

BACKGROUND

Measuring the quality and performance of health care is a major challenge in improving the efficiency of a health system. Patient experience is one important measure of the quality of health care, and the use of patient-reported experience measures (PREMs) is recommended. The aims of this project are 1) to develop item banks of PREMs that assess the quality of health care for adult patients with psychiatric disorders (schizophrenia, bipolar disorder, and depression) and to validate computerized adaptive testing (CAT) to support the routine use of PREMs; and 2) to analyze the implementation and acceptability of the CAT among patients, professionals, and health authorities.

METHODS

This multicenter and cross-sectional study is based on a mixed method approach, integrating qualitative and quantitative methodologies in two main phases: 1) item bank and CAT development based on a standardized procedure, including conceptual work and definition of the domain mapping, item selection, calibration of the item bank and CAT simulations to elaborate the administration algorithm, and CAT validation; and 2) a qualitative study exploring the implementation and acceptability of the CAT among patients, professionals, and health authorities.

DISCUSSION

The development of a set of PREMs on quality of care in mental health that overcomes the limitations of previous works (ie, allowing national comparisons regardless of the characteristics of patients and care and based on modern testing using item banks and CAT) could help health care professionals and health system policymakers to identify strategies to improve the quality and efficiency of mental health care.

Medication nonadherence in bipolar disorder: a narrative review

A number of effective maintenance medication options exist for bipolar disorder (BD) and these are regarded as the foundation of long-term treatment in BD. However, nonadherence to medication is common in BD. For example, a large data base study in the United States of America (USA) showed that approximately half of patients with BD were nonadherent with lithium and maintenance medications over a 12 month period. Such nonadherence carries a high risk of relapse due to the recurrent nature of the illness and the fact that abrupt cessation of treatment, particularly lithium, may cause rebound depression and mania. Indeed, medication nonadherence in BD is associated with significantly increased risks of relapse, recurrence, hospitalization and suicide attempts and a decreased likelihood of achieving remission and recovery, as well as with higher overall treatment costs. Factors associated with nonadherence include adverse effects of medication, complex medication regimens, negative patient attitudes to medication, poor insight, rapid-cycling BD, comorbid substance misuse and a poor therapeutic alliance. Clinicians should routinely enquire about nonadherence in a nonjudgmental fashion. Potential steps to improve adherence include simple pragmatic strategies related to prescribing including shared decision-making, psychoeducation with a clear focus on adherence, reminders (traditional and digital), potentially using a depot rather than an oral antipsychotic, managing comorbid substance misuse and improving therapeutic alliance. Financial incentives have been shown to improve adherence to depot antipsychotics, but this approach raises ethical issues and its long-term effectiveness is unknown. Often a combination of approaches will be required. The strategies that are adopted need to be patient specific, reflecting that nonadherence has no single cause, and chosen by the patient and clinician working together.

Reasons for lithium discontinuation in men and women with bipolar disorder: a retrospective cohort study

BACKGROUND

Lithium remains first choice as maintenance treatment for bipolar affective disorder. Yet, about half of all individuals may stop their treatment at some point, despite lithium's proven benefits concerning the prevention of severe affective episodes and suicide.

METHODS

Retrospective cohort study in the Swedish region of Norrbotten into the causes of lithium discontinuation. The study was set up to (1) test whether patients with bipolar affective disorder or schizoaffective disorder, treated with lithium maintenance therapy, were more likely to discontinue lithium because of adverse effects than lack of therapeutic effectiveness, (2) explore gender differences, (3) understand the role of diagnosis and (4) identify who, patient or doctor, took the initiative to stop lithium. Review of medical records for all episodes of lithium discontinuation that had occurred between 1997 and 2013 with the intent to stop lithium for good.

RESULTS

Of 873 patients treated with lithium, 54% discontinued lithium, corresponding to 561 episodes of lithium discontinuation. In 62% of episodes, lithium was discontinued due to adverse effects, in 44% due to psychiatric reasons, and in 12% due to physical reasons interfering with lithium treatment. The five single most common adverse effects leading to lithium discontinuation were diarrhoea (13%), tremor (11%), polyuria/polydipsia/diabetes insipidus (9%), creatinine increase (9%) and weight gain (7%). Women were as likely as men to take the initiative to stop lithium, but twice as likely to consult a doctor before taking action (p < 0.01). Patients with type 1 BPAD or SZD were more likely to discontinue lithium than patients with type 2 or unspecified BPAD (p < 0.01). Patients with type 1 BPAD or SZD were more likely to refuse medication (p < 0.01). Conversely, patients with type 2 or unspecified BPAD were three times as likely to discontinue lithium for lack or perceived lack of effectiveness (p < 0.001).

CONCLUSIONS

Stopping lithium treatment is common and occurs mostly due to adverse effects. It is important to discuss potential adverse effects with patients before initiation and continuously during lithium treatment, to reduce the frequency of potentially unnecessary discontinuations.

A cornerstone of healthy aging: do we need to rethink the concept of adherence in the elderly?

Worldwide, the population is aging and this trend will increase in the future due to medical, technological and scientific advancements. To take care of the elderly is highly demanding and challenging for the health care system due to their frequent condition of chronicity, multimorbidity and the consequent complex management of polypharmacy. Nonadherence to medications and to medical plans is a well-recognized public health problem and a very urgent issue in this population. For this reason, some considerations to identify a new shared approach to integrated care of older people are described. The concept of adherence should be considered as a complex and continuous process where family, caregivers and patients' beliefs come into play. Moreover, a new culture of adherence should contemplate the complexity of multimorbidity, as well as the necessity to renegotiate the medication regimen on the basis of each patient's needs.
