Summary

Subacute sclerosing panencephalitis (SSPE) patients exhibit autonomic dysfunction, indicated by reduced heart rate variability. This autonomic nervous system impairment may stem from central nervous system involvement in SSPE.

Area of Science:

  • Neurology
  • Autonomic Neuroscience

Background:

  • Subacute sclerosing panencephalitis (SSPE) is a severe, progressive neurological disorder.
  • Autonomic nervous system (ANS) dysfunction is a potential complication of SSPE.

Purpose of the Study:

  • To investigate autonomic nervous system involvement in SSPE patients.
  • To analyze heart rate variability (HRV) in SSPE patients and compare it to healthy controls.

Main Methods:

  • 24-hour Holter recordings were analyzed using time-domain HRV parameters.
  • 29 SSPE patients were compared with 20 age- and sex-matched healthy controls.

Main Results:

  • SSPE patients showed significantly lower standard deviation of normal-to-normal intervals and triangular index compared to controls.

  • No significant association was found between HRV indices and brain MRI findings or patient survival.
  • Autonomic dysfunction was prevalent in SSPE patients, suggesting central nervous system involvement.

    • Conclusions:

    • Autonomic nervous system dysfunction is a significant feature of subacute sclerosing panencephalitis.
    • The observed autonomic dysfunction is likely due to central nervous system pathology in SSPE.
