Doctors are unsure on how or why ALS occurs but some of the cases are inherited.ALS can begin with muscle twitching and weakness of a limb or when an individual starts to slur their speech. Eventually the disease will take control of the muscles needed to move, speak, eat and breathe. Unfortunately there isn't a cure for this fatal disease.Symptoms of ALSDifficulty walking or doing normal daily activitiesTripping and fallingWeakness in your legs, feet or anklesHand weaknesses or clumsinessSlurred speech or trouble swallowingMuscle cramps and twitching in your arms, shoulder and tongueInappropriate crying, laughing or yawningCognitive and behavioral changesThe disease often starts in an individual's hands, feet or limbs. It then spreads to other parts of the individual body. As time passes, ALS destroys the nerve cells and your muscles begin to get weaker. Towards the end it will impact an individual’s ability to chew, swallow, speak and breathe.Steve McMichaels 15-year NFL CareerSteve McMichaelSteve 'Mongo' McMichaels was drafted by the New England Patriots with the 73rd overall pick in the third-round of the 1980 NFL Draft.
