While invasive ventilation prolongs survival, disease progression and functional decline continue. It may decrease the quality of life of people with ALS or their caregivers. Invasive ventilation is more commonly used in Japan than North America or Europe.Physical therapy can promote functional independence through aerobic, range of motion, and stretching exercises. Occupational therapy can assist with activities of daily living through adaptive equipment. Speech therapy can assist people with ALS who have difficulty speaking. Preventing weight loss and malnutrition in people with ALS improves both survival and quality of life. Initially, difficulty swallowing (dysphagia) can be managed by dietary changes and swallowing techniques. A feeding tube should be considered if someone with ALS loses 5% or more of their body weight or if they cannot safely swallow food and water. The feeding tube is usually inserted by percutaneous endoscopic gastrostomy (PEG). There is weak evidence that PEG tubes improve survival. PEG insertion is usually performed with the intent of improving quality of life.Palliative care should begin shortly after someone is diagnosed with ALS. Discussion of end-of-life issues gives people with ALS time to reflect on their preferences for end-of-life care and can help avoid unwanted interventions or procedures. Hospice care can improve symptom management at the end of life and increases the likelihood of a peaceful death. In the final days of life, opioids can be used to treat pain and dyspnea, while benzodiazepines can be used to treat anxiety. Medications
Riluzole has been found to modestly prolong survival by about 2–3 months.
