Brain Trauma and Lou Gehrig’s Disease
The New York Times published a very interesting article describing a new study that suggests that brain trauma–like concussions and other head injuries–can over time cause damage that looks like Lou Gehrig’s disease (Amyotrophic Lateral Sclerosis, or ALS). This might mean that some people diagnosed with ALS actually are suffering from the long-term effects of repeated mild head injuries. This fits in with a lot of new evidence that repeated mild head injuries can have very significant long-term effects on brain health, even if each individual injury seems like it has no lasting effect.
