Summary
This study reports that a severe vitamin D deficiency in amyotrophic lateral sclerosis (ALS) patients accelerates the rate of decline by 4 times and is associated with a marked shorter life expectancy.
The researchers say their findings support a neuroprotective function of vitamin D on motoneurons and propose vitamin D as a reliable prognostic factor of ALS.
Further details can be found in the study.
