JGJiaojiao GuoNathan Kline Institute for Psychiatric ResearchCLChristos Panagiotis LisgarasNathan Kline Institute for Psychiatric Research

Key Points

  • The aim is to assess the role of electroencephalography (EEG) in neurodegenerative diseases and its potential applications in dementia.
  • Comprehensive review of existing literature on EEG in neurodegenerative conditions.
  • Analysis of emerging EEG technologies and their capabilities for revealing brain abnormalities.
  • Discussion on future advancements for EEG practical applications in clinical and research contexts.
  • EEG abnormalities can appear before cognitive symptoms in neurodegenerative diseases.
  • Recent EEG technologies enhance detection of brain function irregularities.
  • Recommendations outlined for improving EEG's utility in clinical dementia evaluations.

Abstract

Abstract Electroencephalography (EEG) offers a non-invasive window into brain function, often revealing abnormalities long before cognitive symptoms or neurodegeneration emerge. This review examines the expanding role of EEG in neurodegenerative disease and comorbid conditions that contribute to abnormal EEG. We review emerging EEG technologies that uncover previously underappreciated EEG abnormalities and outline future steps needed to advance EEG as a practical tool in clinical and research settings for dementia.
