Computerised tracking tests show promise for evaluating antiepileptic drug (AED) effectiveness and monitoring Alzheimer's disease (AD) progression. These reliable and sensitive tests offer a valuable tool for clinical assessments in neurology.

Area of Science:

  • Neuroscience
  • Clinical Neurology
  • Medical Technology

Background:

  • Computerised tracking offers a novel method for assessing cognitive and motor functions.
  • Evaluating the efficacy of antiepileptic drugs (AEDs) and monitoring Alzheimer's disease (AD) progression requires sensitive and reliable assessment tools.

Purpose of the Study:

  • To evaluate the utility of computerised tracking in assessing AED effectiveness in epilepsy patients.
  • To investigate the application of computerised tracking for monitoring Alzheimer's disease progression.
  • To introduce real-time target speed adaptation and signal-processing techniques to simplify experimental protocols.

Main Methods:

  • Clinical study comparing AED blood levels, standard neuropsychological tests, and computerised tracking/reaction time tests in epilepsy patients.

Related Experiment Videos

  • Implementation of real-time target speed adaptation to streamline experiments.
  • Application of signal-processing techniques to analyze computerised tracking data for AD patients.

    • Main Results:

    • Computerised tracking tests demonstrated repeatability, reliability, and sensitivity, indicating their utility in epilepsy treatment evaluation.
    • Variations in optimal speed (OS) were observed within the therapeutic range of AEDs.
    • Signal-processing analysis revealed distinct tracking characteristics in AD patients, mirroring healthy controls' non-preview tracking due to impaired working memory.

    Conclusions:

    • Computerised tracking is a reliable and sensitive tool for evaluating epilepsy treatment and monitoring AD progression.
    • The study highlights the potential of adapted computerised tracking protocols for clinical neurological assessments.
    • Impaired working memory in AD significantly influences motor planning and tracking behavior, as evidenced by the observed tracking modes.
