We report the cases of three elderly patients presenting with insidious mental impairment whilst receiving both lipophilic and hydrophilic beta-adrenoceptor blocking agents (propranolol and atenolol respectively). In each case marked improvement occurred on drug withdrawal. Two of our cases probably had early senile dementia of the Alzheimer's type and continued to exhibit signs of mild mental impairment, but the third was restored to normal functioning. We found no evidence of impaired perfusion to suggest a vascular basis for the effect or of depression. We believe that beta-blockade may cause or exacerbate mental impairment in the elderly.

Breast milk (BM) is the main nutrition source for infants that plays a key role on growth and development. Human milk composition includes endogenous and exogenous substances, including endocrine disrupting chemicals (EDCs). EDCs are man-made environmental chemicals present in everyday environment and food that can disrupt the programming of endocrine signalling pathways during development, resulting in adverse effects that may not be apparent until much later in life.

Objectives: We aimed to explore the impact of glymphatic function in patients diagnosed with autoimmune encephalitis (AE).
Methods: In this prospective longitudinal study, patients were recruited from Xijing Hospital between June 2020 and January 2024. Glymphatic function was evaluated using diffusion tensor imaging analysis along the perivascular space (DTI-ALPS).

Cognitive decline is one of the most significant non-motor symptoms of Parkinson's disease (PD), with executive dysfunction (EDF) being the most prominent characteristic of PD-associated cognitive deficits. Currently, lack of uniformity in the conceptualization and assessment scales for executive functions impedes the early and accurate diagnosis of executive dysfunction in PD. The neurobiological mechanisms of executive dysfunction in PD remain poorly understood.

A qualitative study was conducted to define a preliminary set of 62 items. Item reduction was performed using exploratory factor analysis.

Background: Long-term fear memory storage involves gradual reorganization of supporting brain regions over time, a process termed systems consolidation. Memories initially rely on the hippocampus but gradually shift dependence to the neocortex. Although hippocampal activity drives this transfer, the molecular basis of systems consolidation is largely unknown.
