ABSTRACT
BACKGROUND: Motor neuron disease (MND) is largely understudied in many underdeveloped and developing countries, including the Philippines. The practice and management of MND is generally insufficient, and thus, the quality of life of these patients are consequently compromised. OBJECTIVES: The aim of this study is to determine the clinical profile and describe the management of MND patients seen in the largest tertiary hospital in the Philippines for one year. METHODS: This is a cross-sectional study of MND patients diagnosed clinically and via electromyogram-nerve conduction study (EMG NCS) in the Philippine General Hospital (PGH) from January to December 2022. Clinical characteristics, diagnostics and management information were obtained and summarized. RESULTS: The incidence of MND in our neurophysiology unit was 4.3% (28/648), with amyotrophic lateral sclerosis (ALS) being the most common variant (67.9%, n = 19). Male to Female ratio was 1:1, with the median age of onset of 55 (36-72) years old and median onset duration to diagnosis of 1.5 (0.25-8) years. Limb onset was more prevalent (82.14%, n = 23) with upper limbs initially involved (79.1%, n = 18). Split hand syndrome was found in almost half (53.6%) of the patients. The median ALS functional rating score-revised (ALSFRS-R) and medical research council (MRC) scores were 34 (8-47) and 42(16-60) respectively while the median King's clinical stage was 3 (1-4). Only half of the patients were able to undergo magnetic resonance imaging (MRI) and only one had neuromuscular ultrasound. Only one of the 28 patients was able to take riluzole, and only one was on oxygen support. None had gastrostomy and none used non-invasive ventilation. CONCLUSION: This study showed that the management of MND in the Philippines is largely inadequate and further improvement in the health care system in handling rare neurologic cases must be implemented to enhance their quality of life.
