There are many articles on statins and ALS, and in general the results show that statin use does not influence the progression of ALS.
Statins are commonly used to manage cholesterol levels and reduce the risk of cardiovascular disease, but their safety in amyotrophic lateral sclerosis (ALS) has long been questioned by both patients and their caregivers. Since the mid-1990s, weight loss has been identified as a contributing factor for patients with ALS, leading to a 7.7-fold increased risk of death. Many individuals worry that statins may accelerate the progression of ALS or exacerbate symptoms, and reports from drug monitoring systems suggest a potential link between a diagnosis of ALS and statin use; however, these reports have yet to be validated in epidemiological studies. In contrast, findings from more recent studies indicate that high LDL cholesterol and elevated LDL/high-density lipoprotein ratios occurring well before the onset of ALS may be associated with an increased risk of developing the disease.
A new Norwegian study on this topic confirms that statin use does not impact the progression of ALS.

The researchers analyzed data from four Norwegian health surveys spanning the years from 1972 to 2003. They linked these surveys to national registries to track ALS diagnoses, mortality, and medication use. Specifically, they examined whether statin use before and after an ALS diagnosis influenced survival time.
The researchers included 524 ALS patients in the analysis. They compared statin use before and after diagnosis and adjusted for various factors, including age, sex, smoking status, BMI, cholesterol levels, and use of riluzole (the main ALS drug).
Their work found no association between statin use and ALS survival. Interestingly, 21% of ALS patients stopped taking statins in the year before their diagnosis. This group had a poorer prognosis, perhaps because of worsening general health, but the fact they stopped using statins did not appear to have improved ALS survival.
The study therefore suggests that routinely stopping statins in ALS patients is not necessary. Since statins do not appear to have a negative impact on survival, stopping them solely because of an ALS diagnosis may deprive patients of their cardiovascular benefits.
