Nineteen elderly--ten healthy and nine Alzheimer patients--were given a naming-generation task. Their responses were analyzed according to word-type and inter-word relatedness. The results were correlated with the Mini-Mental-State Examination (MMSE) and examined to elucidate time-dependency. In healthy subjects it was found that time-dependency exists for the number of new words and for percent of phonetically-related words, while for Alzheimer patients, time-dependency was exhibited in new words only. Results are discussed in terms of the principles of semantic-memory organization and time-dependency of cognitive-linguistic functions.

Brain iron deposition and cognitive decline in patients with cerebral small vessel disease : a quantitative susceptibility mapping study.
Alzheimers Res Ther
January 2025
Department of Radiology, Weill Medical College of Cornell University, New York, NY, USA, Meinig School of Biomedical Engineering, Cornell University, Ithaca, NY, USA.
Background: Quantitative susceptibility mapping (QSM) can study the susceptibility values of brain tissue which allows for noninvasive examination of local brain iron levels in both normal and pathological conditions.
Purpose: Our study compares brain iron deposition in gray matter (GM) nuclei between cerebral small vessel disease (CSVD) patients and healthy controls (HCs), exploring factors that affect iron deposition and cognitive function.
Materials And Methods: A total of 321 subjects were enrolled in this study.

Background: Blood-brain barrier dysfunction is one characteristic of Alzheimer's disease (AD) and is recognized as both a cause and consequence of the pathological cascade leading to cognitive decline. The goal of this study was to assess markers for barrier dysfunction in postmortem tissue samples from research participants who were either cognitively normal individuals (CNI) or diagnosed with AD at the time of autopsy and determine to what extent these markers are associated with AD neuropathologic changes (ADNC) and cognitive impairment.
Methods: We used postmortem brain tissue and plasma samples from 19 participants: 9 CNI and 10 AD dementia patients who had come to autopsy from the University of Kentucky AD Research Center (UK-ADRC) community-based cohort; all cases with dementia had confirmed severe ADNC.
Neuropathological contributions to grey matter atrophy and white matter hyperintensities in amnestic dementia.
Alzheimers Res Ther

Laboratory for Clinical Neuroscience, Center for Biomedical Technology, Universidad Politécnica de Madrid, IdISSC, Crta M40, km38, Madrid, 28223, Spain.
Background: Dementia patients commonly present multiple neuropathologies, worsening cognitive function, yet structural neuroimaging signatures of dementia have not been positioned in the context of combined pathology. In this study, we implemented an MRI voxel-based approach to explore combined and independent effects of dementia pathologies on grey and white matter structural changes.
Methods: In 91 amnestic dementia patients with post-mortem brain donation, grey matter density and white matter hyperintensity (WMH) burdens were obtained from pre-mortem MRI and analyzed in relation to Alzheimer's, vascular, Lewy body, TDP-43, and hippocampal sclerosis (HS) pathologies.
Nose-to-brain delivery of DHA-loaded nanoemulsions: A promising approach against Alzheimer's disease.

Reduced docosahexaenoic acid (DHA) concentrations seem to be associated with an increased risk of Alzheimer's disease (AD), and DHA accretion to the brain across the blood-brain-barrier (BBB) can be modulated by various factors. Therefore, there is an urgent need to identify an efficient and non-invasive method to ensure brain DHA enrichment. In the present study, a safe and stable DHA-enriched nanoemulsion, designed to protect DHA against oxidation, was designed and administered intranasally in a transgenic mouse model of AD, the J20 mice.

Exposure to sound energy may be a risk factor or a therapeutic intervention for Alzheimer's disease (AD). On one hand, noise has a harmful effect on people with AD by contributing to hearing loss, sleep disturbance, oxidative stress, inflammation, and excitotoxicity. But on the other hand, clinical trials and nursing home interventions with soundscape augmentation involving natural sounds have shown promising results in alleviating psychophysiological symptoms in people with AD.
