Nutritional management in amyotrophic lateral sclerosis: a worldwide perspective

Area of Science:

• Neurology
• Clinical Nutrition
• Palliative Care

Background:

• Amyotrophic lateral sclerosis (ALS) primarily causes death through respiratory failure.
• Nutritional status management is vital for improving quality of life and optimizing intervention timing in ALS patients.
• Progressive muscle weakness leads to eating difficulties and severe dysphagia in nearly all ALS patients.

Purpose of the Study:

• To describe the nutritional needs of ALS patients from a global and cross-cultural perspective.
• To address differences between paternalistic and patient-centered approaches in ALS nutritional management.
• To discuss the need for further research on ALS patient nutritional status and nutritional therapies.

Main Methods:

• Review of global and cross-cultural nutritional needs in ALS.
• Analysis of paternalistic versus patient-centered care models.
• Discussion of parenteral and enteral nutritional therapy, including percutaneous endoscopic gastrostomy (PEG).

Main Results:

• ALS patients face significant challenges with food and fluid intake due to dysphagia and muscle weakness.
• Malnutrition and weight loss are common if nutritional support is inadequate.
• Impaired respiratory function increases energy demands, further complicating nutritional management.

Conclusions:

• Comprehensive nutritional assessment and support are essential for ALS patient care.
• A patient-centered approach is recommended for nutritional management, respecting patient autonomy.
• Further research is needed on optimal nutritional strategies, including enteral feeding methods like PEG.
