Background: Spatial orientation is required for independent mobility in society. Deficits in spatial orientation can be an early symptom of Alzheimer's disease and other dementias, and there is a need for brief assessment tools to identify impairments.

Objective: The aim of this study was to evaluate the construct and known-group validity of our newly developed Spatial Orientation Screening (SOS) questionnaire.

Background: Sex differences in neuroinflammation could contribute to women's increased risk of Alzheimer's disease (AD), providing rationale for exploring sex-specific AD biomarkers. In AD, dysregulation of the kynurenine pathway (KP) contributes to neuroinflammation and there is some evidence of sex differences in KP metabolism. However, the sex-specific associations between KP metabolism and biomarkers of AD and neuroinflammation need to be explored further.

Article Synopsis
  • The study aimed to determine if MRI software, NeuroQuant®, could effectively predict cognitive decline in patients showing early signs of cognitive issues.
  • It analyzed data from 156 patients at Oslo University Hospital, looking at the relationship between hippocampus volume, whole brain volume, and the progression of cognitive decline over time.
  • Findings suggested that while hippocampus volume correlates with conversion to mild cognitive impairment or dementia, it, along with whole brain volume, is useful for assessing the rate of cognitive decline, highlighting the potential of MRI in early diagnosis.

Background And Purpose: The aims were to compare the novel regional brain volumetric measures derived by the automatic software NeuroQuant (NQ) with clinically used visual rating scales of medial temporal lobe atrophy (MTA), global cortical atrophy-frontal (GCA-f), and posterior atrophy (PA) brain regions, assessing their diagnostic validity, and to explore if combining automatic and visual methods would increase diagnostic prediction accuracy.

Methods: Brain magnetic resonance imaging (MRI) examinations from 86 patients with subjective and mild cognitive impairment (i.e.

Background And Aims: We have previously shown that systemic inflammation was associated with post-stroke cognitive impairment (PSCI). Because neopterin, kynurenine pathway (KP) metabolites, and B6 vitamers are linked to inflammation, in our study we investigated whether those biomarkers were associated with PSCI.

Material And Methods: The Norwegian Cognitive Impairment After Stroke study is a prospective multicenter cohort study of patients with acute stroke recruited from May 2015 through March 2017.
