AD Alzheimer’s disease, ALSFRS-R ALS Functional Rating Scale-revised version, BMI body mass index, CTRL controls, DPI disease progression index, EN enteral nutrition, MMSE Mini-Mental State Examination, na not available, NIV non-invasive ventilation, TDP43 + ALS patients carrying a pathogenic TARDBP mutation. Data are shown as mean ± SD.

aThe DPI was calculated as [48-ALSFRS-R score]/disease duration (months) for ALS patients and [30-MMSE score]/disease duration (months) for AD patients.
