Low DHT and ALS (Amyotrophic lateral sclerosis)

According to this study (https://onlinelibrary.wiley.com/doi/full/10.1002/brb3.1645#brb31645-sec-0008-title) lower DHT levels are associated with ALS! I’m worried that this means finasteride, something that lowers DHT, can maybe cause ALS even thought it’s rare! Thoughts?

From reading the article quickly, I did not see a 1:1 connection between low DHT and ALS. The authors postulated that low DHT may have a role, but the evidence is not strong.
