    This study links multiple sclerosis disability to specific EEG brainwave patterns. Immunosuppressive therapy improved patient condition and altered alpha wave activity.

    Area of Science:

    • Neuroscience
    • Clinical Neurology

    Background:

    • Multiple Sclerosis (MS) is a chronic autoimmune disease affecting the central nervous system.
    • Clinical and biochemical markers, including cerebrospinal fluid oligoclonal bands, confirm MS diagnosis.
    • Disease progression and disability vary significantly among patients.

    Purpose of the Study:

    • To investigate the relationship between disability severity and electroencephalogram (EEG) spectral analysis in multiple sclerosis patients.
    • To evaluate the impact of intensive immunosuppressive therapy on clinical status and EEG patterns in MS.

    Main Methods:

    • Disability scoring and EEG-spectral analysis were conducted on MS patients at two time points: before and after immunosuppressive therapy.
    • Cerebrospinal fluid analysis confirmed MS diagnosis, noting oligoclonal bands.

  • EEG data focused on beta activity (fronto-central) and theta activity (temporal) in relation to disability, and alpha frequency (parietooccipital) changes post-therapy.

    • Main Results:

    • A correlation was observed between the degree of disability and increased beta activity in the fronto-central regions and increased theta activity in the temporal regions.
    • Following short-term intensive immunosuppressive therapy, patients showed significant clinical improvement.
    • A notable increase in mean alpha frequency in the parietooccipital region was observed post-treatment.

    Conclusions:

    • EEG spectral analysis can reveal correlations between brainwave activity and disability levels in multiple sclerosis.
    • Intensive immunosuppressive therapy demonstrates efficacy in improving clinical outcomes and altering specific EEG parameters in MS patients.
