Recent studies have identified cognitive deficits in semantic memory and verbal language abilities among women with Alzheimer's disease (AD). Few studies to date have explored gender differences in episodic memory function in AD. The present study compared the performance of men and women diagnosed with AD on a battery of neuropsychological measures. Results indicated the presence of gender-related cognitive deficits on tasks of confrontation naming, expressive word knowledge, and both episodic and semantic memory for women with AD, relative to findings in men.

Introduction: Subjective cognitive decline (SCD) is linked to memory complaints and disruptions in certain brain regions identified by molecular imaging and resting-state functional magnetic resonance imaging studies. However, it remains unclear how these regions interact to contribute to both subjective and potential objective memory issues in SCD.
Methods: To address this gap, task-based imaging studies are essential.

Introduction: Neuropsychiatric symptoms (NPSs) are common in dementia with Lewy bodies (DLB) but their neurobiological mechanisms are poorly understood.
Methods: NPSs and cognition were assessed annually in participants (DLB n = 222; Alzheimer's disease [AD] n = 125) from the European DLB (E-DLB) Consortium, and plasma phosphorylated tau-181 (p-tau181) and p-tau231 concentrations were measured at baseline.
Results: Hallucinations, delusions, and depression were more common in DLB than in AD and, in a subgroup with longitudinal follow-up, persistent hallucinations and NPSs were associated with lower p-tau181 and p-tau231 in DLB.

Introduction: The longitudinal progression of synaptic loss in Alzheimer's disease (AD) and how it is affected by tau pathology remains poorly understood.
Methods: Thirty patients with amnestic mild cognitive impairment (aMCI) and 26 healthy controls underwent cognitive evaluations and tau, synaptic vesicle protein 2A (SV2A), and amyloid positron emission tomography. Twenty-one aMCI underwent 2-year follow-up (FU) investigations.

Alzheimer's disease (AD) is a neurodegenerative disease that is significantly characterized by cognitive and memory impairments, which worsen significantly with age. In the late stages of AD, metal ion disorders and an imbalance of reactive oxygen species (ROS) levels occur in the brain microenvironment, which causes abnormal aggregation of β-amyloid (Aβ), leading to a significant worsening of the AD symptoms. Therefore, we designed a composite nanomaterial of macrophage membranes-encapsulated Prussian blue nanoparticles (PB NPs/MM).
