how does the immune system get affected by als
ALS or Lou Gehrigâs Disease. ALS (Amyotrophic Lateral Sclerosis) or Lou Gehrigâs Disease is considered an âautoimmune disease,â meaning something foreign to the brain is getting into the brain. The immune system recognizes the invader and attacks. The immune system is not able to get rid of, or kill, the invader and for some reason the immune system does not âturn off.â. Because the immune system does not âturn offâ, the immune system itself causes some of the damage to the brain. However, there may be multiple reasons, or multiple ways of looking at, the causes of ALS. ALS is almost always caused by Lyme Disease (aka Lymes Disease).
