Article Synopsis
  • - The study examined the effects of education, smoking, and alcohol use disorder (AUD) on dementia risk in older adults, aiming to understand how these factors might influence dementia differently among various subgroups.
  • - Using data from the National Alzheimer's Coordinating Center (2005-2021), researchers found that a college education was linked to a decreased risk of dementia, particularly in people without hypertension, while smoking and AUD had varying effects based on specific health conditions.
  • - The findings highlight the need for a personalized approach in addressing dementia risk, as different factors significantly impact certain groups, suggesting that interventions should be tailored to individual health profiles.

Article Synopsis
  • SGLT2 inhibitors may help lower the risk of all-cause dementia in individuals with type 2 diabetes (T2D), with studies showing a significantly lower incidence compared to those taking sulfonylureas.
  • In a study involving over 35,000 T2D patients, 1.8% on SGLT2 inhibitors developed dementia versus 4.7% on sulfonylureas, indicating a risk difference of -2.5% across a 3.2-year follow-up.
  • Subgroup analysis revealed that Hispanic ethnicity and chronic kidney disease influenced the risk reduction, suggesting that not all patients with T2D benefit equally from SGLT2 inhibitors

Behavioral neurology & neuropsychiatry (BNNP) is a field that seeks to understand brain-behavior relationships, including fundamental brain organization principles and the many ways that brain structures and connectivity can be disrupted, leading to abnormalities of behavior, cognition, emotion, perception, and social cognition. In North America, BNNP has existed as an integrated subspecialty through the United Council for Neurologic Subspecialties since 2006. Nonetheless, the number of behavioral neurologists across academic medical centers and community settings is not keeping pace with increasing clinical and research demand.

Objective measures of disease progression are critically needed in research on Parkinson's disease (PD) and atypical Parkinsonism but may be hindered by both practicality and cost. The Purdue Pegboard Test (PPT) is objective, has high test-retest reliability, and has a low cost. The goals of this study were to determine: (1) longitudinal changes in PPT in a multisite cohort of patients with PD, atypical Parkinsonism, and healthy controls; (2) whether PPT performance reflects brain pathology revealed by neuroimaging; (3) quantify kinematic deficits shown by PD patients during PPT.

Overly restricted and poorly designed eligibility criteria reduce the generalizability of the results from clinical trials. We conducted a study to identify and quantify the impacts of study traits extracted from eligibility criteria on the age of study populations in Alzheimer's Disease (AD) clinical trials. Using machine learning methods and SHapley Additive exPlanation (SHAP) values, we identified 30 and 34 study traits that excluded older patients from AD trials in our 2 generated target populations respectively.

Sleep problems are common among veterans with post-traumatic stress disorder and closely associated with hyperarousal symptoms. Transcutaneous vagus nerve stimulation (tVNS) may have potential to improve sleep quality in veterans with PTSD through effects on brain systems relevant to hyperarousal and sleep-wake regulation. The current pilot study examines the effect of 1 h of tVNS administered at "lights out" on sleep architecture, microstructure, and autonomic activity.

To estimate the prevalence rates of Alzheimer's disease and related dementias (ADRD) and their risk factors in the transgender population and compare the rates to those in cisgender adults. We identified 1784 transgender adults in the linked electronic health records and claims data between 2012 and 2020 from the OneFlorida Clinical Research Consortium. We calculated the prevalence of ADRD and ADRD risk factors for the transgender and matched cisgender control adults.

Purpose Of Review: This article provides a synopsis of current assessment and treatment considerations for posttraumatic stress disorder (PTSD) and related anxiety disorder characteristics. Epidemiologic and neurobiological data are reviewed as well as common associated symptoms, including sleep disruption, and treatment approaches to these conditions.

Recent Findings: PTSD is no longer considered an anxiety-related disorder in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition classification and instead is associated with trauma/stressor-related disorders.

Prognostic modeling in moderate to severe traumatic brain injury (TBI) has historically focused primarily on the projection of crude outcomes such as the risk of mortality and disability. Initial work in this area has perpetuated the notion that prognosis after moderate to severe TBI can be measured as a single, static, and dichotomous outcome. However, more recent conceptualizations describe moderate to severe TBI as the initiation of a chronic disease state with high levels of inter-individual variability in terms of symptom manifestation and disease progression.
