Area of Science:

  • Biochemistry
  • Cellular Biology
  • Neurology

Background:

  • Oxidative phosphorylation (OXPHOS) is crucial for cellular energy production, generating ~95% of cellular ATP.
  • Dysfunction in OXPHOS affects various tissues, particularly the nervous system and muscles.
  • Neuromuscular manifestations are common and critical for diagnosing OXPHOS diseases.

Purpose of the Study:

  • To focus on OXPHOS diseases with distinct neuromuscular abnormalities.
  • To present a diagnostic evaluation algorithm for neurologists.
  • To aid in the clinical assessment of patients with suspected OXPHOS disorders.

Main Methods:

  • Review of selected OXPHOS diseases with neuromuscular involvement.
  • Development of a diagnostic algorithm based on clinical presentation.
  • Focus on characteristic neuromuscular findings.

Main Results:

  • Identified key OXPHOS diseases presenting with significant neuromuscular symptoms.
  • Outlined an algorithm to guide neurologists through the diagnostic process.
  • Highlighted the importance of neuromuscular evaluation in OXPHOS disease diagnosis.

Conclusions:

  • Neuromuscular symptoms are key indicators in many OXPHOS diseases.
  • A structured diagnostic approach can improve the identification of these disorders.
  • The proposed algorithm assists neurologists in evaluating patients with OXPHOS-related neuromuscular conditions.
