I have read about 5 to 10% of all ALS cases are inherited. What does that mean? that 10% of people who have als, their children will get als too ? I am looking at my twitches quite differently after I heard of my dad's diagnosed. Frankly its freaking me out and i am considering getting it checked. Anyone has any thoughts on what the children of pals can do in terms of early detection and / or monitoring ?
