Supporting evidence — 5 representative gaps

• Sensory impairment and cognitive-state transitions in middle-aged and older adults: a multistate Markov analysis of the health and retirement study (2026) · Frontiers in Aging Neuroscience · doi

  Further research is needed to investigate the causal relationships between sensory impairment and cognitive decline. Studies should examine the effects of interventions aimed at preventing or treating sensory impairment on cognitive outcomes. Research should explore the mechanisms underlying the associations between sensory impairment and cognitive decline.

• Multimodal EEG and explainable machine learning characterize neuroticism-related neurodynamic heterogeneity in mild cognitive impairment during visuospatial working memory (2026) · Frontiers in Aging Neuroscience · doi

  The study identifies a gap in the current understanding of the neural mechanisms underlying cognitive decline in individuals with mild cognitive impairment and elevated neuroticism. The study highlights the need for further research on the role of neuroticism in cognitive decline. The study suggests that personalized interventions for cognitive decline may be developed based on the study's findings.

  Further studies are needed to investigate the underlying mechanisms of the observed deficits. Studies should examine the relationship between physiological deficits in hippocampal synaptic plasticity and deficits in behavioral plasticity in more detail. Studies should investigate the neural mechanisms underlying age-related cognitive decline.
