We come upon studies like this all the time because "they" are trying to disprove what's really going on, and wish to keep the 'status quo'.
"No association between Borrelia burgdorferi antibodies and amyotrophic lateral sclerosis in a case–control study"
onlinelibrary.wiley.com/doi/10.1111/ene.13197/abstract "A total of 491 patients with ALS were matched to 982 controls. IgG titers against B. burgdorferi were determined by an enzyme-linked immunosorbent assay and, in the case of positivity or borderline results, a western blot was performed."
This right here is a HUGE red flag for false results. We KNOW that the Western Blot (WB) can often have a false negative result. Several states now have laws on the books stating that a doctor must tell a patient that even with a negative WB it does NOT mean you don't have Lyme. Why is this?
Because the WB relies on the person's immune function to be normal, yet it's been proven many times that Lyme inhibits the normal function of the immune system - and yet, this faulty test is still used over and over again to 'prove' that Lyme isn't something that's affecting people.
So, their next statement, "No difference in seroprevalence of Borrelia was found between patients (4.1%) and controls (5.9%). " , says a lot. No one knows if those with a negative WB actually still had Lyme. With a minimum of 400,000 NEW patients each year, it's safe to assume that at least many with negative WB's are still infected with Borrelia.
Their statement of "This large case–control study provides evidence for a lack of association between B. burgdorferi antibodies and ALS," simply isn't true, and the really sad part is they know it. How? The issues with the WB have been well documented, they just choose to not acknowledge it because it suits their needs to "prove" ALS is never Lyme - but if you visit these Lyme forums often enough, you will see that that is not the case. There ARE cases of ALS that are truly Lyme disease.
