Summary: Postoperative delirium is a common complication for elderly patients. This study examined the association of apolipoproteins with delirium after surgery. Serum levels of apolipoprotein A-I and B were increased in patients with delirium whereas those of apolipoprotein E were decreased. These changes in apolipoprotein A-I and E levels were associated with the presence of phosphorylated neurofilament heavy subunit in the serum and were significantly associated with delirium.

Summary: DSD, occurring in older hospitalized patients with preexisting dementia, leads to worse outcomes compared with delirium or dementia alone. Diagnosis and management can be challenging due to cognitive dysfunction being common in both delirium and dementia. Future research opportunities lie in studying shared pathophysiological pathways to uncover diagnostic tests and therapeutic innovations.

Summary: This study examines the healthcare costs associated with delirium in older hospitalized patients with and without Alzheimer's disease and related dementias (ADRD). The findings show that patients with ADRD are more likely to develop delirium and have higher costs associated with delirium compared to non-ADRD patients. The costs increase progressively over the course of one year for ADRD patients, while the increase is consistent across time periods for non-ADRD patients.

Summary: This study aimed to investigate the potential of a brief point-of-care EEG measurement for diagnosing delirium superimposed on dementia (DSD). The results showed that higher activities of delta and theta1, and lower activities of theta2, alpha, and beta activity were found in DSD compared to dementia alone. The ratio of delta and theta power during eyes-open conditions had the highest accuracy in distinguishing DSD from dementia alone.

Summary: This study investigated the modulation of APOE on cerebral atrophy and its role in the conversion from cognitive normal (CN) to dementia using a voxel-wise whole-brain perspective. The results revealed that APOE epsilon 4 carriers showed faster-accelerated atrophy in the left hippocampus compared to noncarriers, and both CN2D epsilon 4 carriers and noncarriers exhibited a faster atrophic speed than CN epsilon 4 carriers. These findings were replicated in a sub-sample with strict demographic matching.

Summary: This article describes the challenges in clinical diagnosis and management of Lewy body disease (LBD) and delirium. Distinguishing delirium from LBD is particularly challenging as they share common clinical characteristics. The under and over diagnosis of delirium, as well as the under and over treatment of symptoms, can compromise the care and safety of individuals with LBD. Clinicians currently have a limited set of evidence-based management options for delirium in the context of an LBD diagnosis.

Summary: The study investigated whether a dementia-friendly hospital program improved detection and management of patients with cognitive impairment and risk of delirium at an acute-care hospital. Although the program did not significantly increase identification of patients with cognitive impairment, there was an increase in 4AT screening within 24 hours, implementation of non-pharmacological interventions, and a reduction in prescription of certain medications.

Summary: Delirium presents significant challenges and affects a large proportion of older hospitalized adults. The care for delirium is generally poor, but there have been recent policy advances and increased research output. This article highlights three areas that have the potential to transform delirium practice and knowledge. These areas include addressing the distress caused by delirium, advancing delirium epidemiology research, and improving the assessment of delirium severity. There is still progress to be made, but innovation in these areas can lead to exciting possibilities in enhancing patient care.

Summary: This study found that dementia is associated with many comorbidities and Apolipoprotein E (ApoE) polymorphism. Homozygous epsilon 4 carriers have a higher risk of dementia, with the peak age at 65-75 years. Cerebrovascular accident, sleep disorder, and functional gastrointestinal disorders are significantly associated with dementia.

Summary: This study presents a cultural neuropsychological approach to prestatistical harmonization of cognitive data across the United States and Mexico. By comparing linguistic and cultural equivalence, the researchers identified confident and tentative linking items. Results showed that a significant proportion of the linking items exhibited measurement differences across cohorts. The study highlights the importance of multidisciplinary and multilingual teams in identifying differences in cognitive construct measurement that may not be detected by statistical procedures alone.

Summary: This study aimed to link self-perceived cognitive functioning data from international aging studies using item response theory. The results demonstrated that a single-factor structure was reasonable for the latent trait, and identified top items that made the greatest contribution to measurement precision. This allows for joint or pooled analyses across international studies and may lead to the development of new self-perceived cognitive functioning questionnaires.

Summary: This study found that intensive pharmacologic antihypertensive treatment was associated with a greater risk of adverse events among hospitalized older adults with elevated blood pressures. These findings do not support the treatment of elevated inpatient blood pressures without evidence of end organ damage, and highlight the need for randomized clinical trials of inpatient blood pressure treatment targets.

Summary: This prospective cohort study examined the patterns and pace of cognitive decline up to 72 months following postoperative delirium in older adults. The study found that there was an accelerated cognitive decline rate of 0.14 population SD units per year in those who developed delirium after surgery, compared to the long-term cognitive decline rate of 0.10 population SD units per year in those who did not develop delirium or did not undergo surgery. Delirium was associated with continued cognitive decline for 72 months, but it remains uncertain whether delirium causes subsequent cognitive decline or if individuals with preclinical brain disease are more susceptible to delirium.

Summary: The objective of this study was to identify the clinical features that result in a later age at ASD diagnosis in females. The study found that females were diagnosed with ASD on average 14 months later than males in the sample. This delay in diagnosis was associated with mild or atypical presentation, limited repetitive behaviors, intact IQ and language skills, and later emergence of recognized symptoms. This highlights the need for improved screening methods for ASD in females.
