Essential New Complexity-Based Themes for Patient-Centered Diagnosis and Treatment of Dementia and Predementia in Older People: Multimorbidity and Multilevel Phenomenology

Dementia is a highly prevalent condition with devastating clinical and socioeconomic sequela. It is expected to triple in prevalence by 2050. No treatment is currently known to be effective. Symptomatic late-onset dementia and predementia (SLODP) affects 95% of patients with the syndrome. In contrast to trials of pharmacological prevention, no treatment is suggested to remediate or cure these symptomatic patients. SLODP but not young onset dementia is intensely associated with multimorbidity (MUM), including brain-perturbating conditions (BPCs). Recent studies showed that MUM/BPCs have a major role in the pathogenesis of SLODP. Fortunately, most MUM/BPCs are medically treatable, and thus, their treatment may modify and improve SLODP, relieving suffering and reducing its clinical and socioeconomic threats. Regrettably, the complex system features of SLODP impede the diagnosis and treatment of the potentially remediable conditions (PRCs) associated with them, mainly due to failure of pattern recognition and a flawed diagnostic workup. We suggest incorporating two SLODP-specific conceptual themes into the diagnostic workup: MUM/BPC and multilevel phenomenological themes. By doing so, we were able to improve the diagnostic accuracy of SLODP components and optimize detecting and favorably treating PRCs. These revolutionary concepts and their implications for remediability and other parameters are discussed in the paper.

Towards an improved dementia care experience in clinical radiography practice: A state-of-the-art review

INTRODUCTION

The increasing global incidence rate of dementia and associated co/multimorbidity has consequently led to a rise in the number of people with dementia (PwD) requiring clinical radiography care services. This review aims to explore and integrate findings from diverse settings with a focus on the experiences of PwD and stakeholders, towards the development of a holistic approach for dementia care and management within the context of radiography services.

METHOD

An electronic search was performed across the following databases: PUBMED, CINAHL, Medline, SCOPUS, and ScienceDirect for articles published from January 2009 and June 2023. Articles were included if they fulfilled a predefined criteria mainly focused on experiences of PwD and/or other stakeholders when using the radiography services. Data obtained from the included studies were analysed using a result-based convergent synthesis.

RESULT

Eleven studies from diverse settings met the inclusion criteria. A mix of both positive and negative experiences of PwD and stakeholders were reported following visits to radiology and radiotherapy departments were highlighted across settings. The findings were themed around the need for: person-centred care, effective communication, attitudinal changes of staff, specialised and improved clinical environment and inclusion of caregivers for the care of PwD.

DISCUSSION

This study emphasise the critical importance of adopting holistic approaches to caring for PwD. This involves adopting a person-centred approach, actively involving caregivers, effective communication, and adequate training for radiographers to provide quality services, all in dementia-friendly environments.

CONCLUSION

The experiences of various stakeholders highlight the need for a more holistic approach and strategy for the care and management of PwD within the context of the radiography services. This calls for an urgent need for a comprehensive strategy that includes awareness creation of staff to enhance the quality of care and the overall experience for PwD using the radiography services.

The Association Between Surgery and Mild Cognitive Impairment: Insight from a Case-Control Study

BACKGROUND

Surgery may be associated with postoperative cognitive impairment in elder participants, yet the extent of its association with mild cognitive impairment (MCI) remains undetermined.

OBJECTIVE

To determine the relationship between surgery and MCI.

METHODS

The data of participants from the Alzheimer's Disease Neuroimaging Initiative were analyzed, including individuals with MCI or normal cognition. We focused on surgeries conducted after the age of 45, categorized by the number of surgeries, surgical risk, and the age at which surgeries occurred. Multivariable logistic regression was employed to determine the association between surgery and the development of MCI.

RESULTS

The study is comprised of 387 individuals with MCI and 578 cognitively normal individuals. The overall surgery exposure (adjusted OR = 1.14, [95% CI 0.83, 1.56], p = 0.43) and the number of surgeries (adjusted OR = 0.92  [0.62, 1.36], p = 0.67 for single exposure, adjusted OR = 1.12 [0.71, 1.78], p = 0.63 for two exposures, adjusted OR = 1.38 [0.95, 2.01], p = 0.09 for three or more exposures compared to no exposure as the reference) were not associated with the development of MCI. However, high-risk surgeries (adjusted OR = 1.79 [1.00, 3.21], p = 0.049) or surgeries occurring after the age of 75 (adjusted OR = 2.01 [1.03, 3.90], p = 0.041) were associated with a greater risk of developing MCI.

CONCLUSIONS

High risk surgeries occurring at an older age contribute to the development of MCI, indicating a complex of mechanistic insights for the development of postoperative cognitive impairment.

A Systematic Review on the Potential Acceleration of Neurocognitive Aging in Older Cancer Survivors

As survival rates increase, more emphasis has gone to possible cognitive sequelae in older cancer patients, which could be explained by accelerated brain aging. In this review, we provide a complete overview of studies investigating neuroimaging, neurocognitive, and neurodegenerative disorders in older cancer survivors (>65 years), based on three databases (Pubmed, Web of Science and Medline). Ninety-six studies were included. Evidence was found for functional and structural brain changes (frontal regions, basal ganglia, gray and white matter), compared to healthy controls. Cognitive decline was mainly found in memory functioning. Anti-hormonal treatments were repeatedly associated with cognitive decline (tamoxifen) and sometimes with an increased risk of Alzheimer's disease (androgen deprivation therapy). Chemotherapy was inconsistently associated with later development of cognitive changes or dementia. Radiotherapy was not associated with cognition in patients with non-central nervous system cancer but can play a role in patients with central nervous system cancer, while neurosurgery seemed to improve their cognition in the short-term. Individual risk factors included cancer subtypes (e.g., brain cancer, hormone-related cancers), treatment (e.g., anti-hormonal therapy, chemotherapy, cranial radiation), genetic predisposition (e.g., APOE, COMT, BDNF), age, comorbidities (e.g., frailty, cognitive reserve), and psychological (e.g., depression, (post-traumatic) distress, sleep, fatigue) and social factors (e.g., loneliness, limited caregiver support, low SES). More research on accelerated aging is required to guide intervention studies.

Prevalence and health outcomes in community-dwelling older adults with comorbid cancer and dementia: a longitudinal analysis

OBJECTIVES

To examine health outcomes in community-dwelling older adults with: dementia only, cancer only, and comorbid cancer and dementia.

METHODS

Longitudinal analysis was conducted using data from 2010 to 2016 waves of the Health and Retirement Study. Health outcomes included mortality, limitations in activities of daily living (ADL) and instrumental activities of daily living (IADL), nursing home utilization, hospital stay, homecare use, self-rated health, and out-of-pocket medical expenditure. Panel regression was used for statistical analysis.

RESULTS

The prevalence of comorbid cancer and dementia ranged from 2.56% to 2.97%. Individuals with comorbid cancer and dementia demonstrated a higher likelihood of nursing home utilization and poorer self-rated health but a lower likelihood of hospital stay, homecare use, and out-of-pocket expenditures, compared to the cancer only or dementia only groups. The differences in mortality and ADL and IADL limitations were not statistically significant.

CONCLUSION

Comorbid cancer and dementia predicted longer nursing home utilization and poorer self-rated health. The results help guide care planning for individuals with comorbid cancer and dementia.
