Amyotrophic lateral sclerosis

Amyotrophic lateral sclerosis (ALS) is a specific disorder that involves the death of neurons. In a number of countries the term motor neurone disease (MND) is commonly used, while others use that term for a group of five conditions of which ALS is the most common. ALS is characterized by stiff muscles, muscle twitching, and gradually worsening weakness due to muscles decreasing in size. This results in difficulty speaking, swallowing, and eventually breathing.

The cause is not known in 90% to 95% of cases. About 5–10% of cases are inherited from a person's parents. About half of these genetic cases are due to one of two specific genes. It results in the death of the neurons that control voluntary muscles. The diagnosis is based on a person's signs and symptoms with testing done to rule out other potential causes.

There is no known cure for ALS. A medication called riluzole may extend life expectancy by about two to three months.Non-invasive ventilation may result in both improved quality and length of life. The disease usually starts around the age of 60 and in inherited cases around the age of 50. The average survival from onset to death is three to four years. About 10% survive longer than 10 years. Most die from respiratory failure. In much of the world, rates of ALS are unknown. In Europe and the United States, the disease affects about 2 people per 100,000 per year.

Lou Gehrig

Henry Louis "Lou" or "Buster"Gehrig (Born Heinrich Ludwig Gehrig; June 19, 1903 – June 2, 1941) was an American baseball first baseman who played 17 seasons in Major League Baseball (MLB) for the New York Yankees, from 1923 through 1939. Gehrig was renowned for his prowess as a hitter and for his durability, a trait which earned him his nickname "The Iron Horse". He was an All-Star seven consecutive times, a Triple Crown winner once, an American League (AL) Most Valuable Player twice, and a member of six World Series champion teams. He had a career .340 batting average, .632 slugging average, and a .447 on base average. He hit 493 home runs and had 1,995 runs batted in (RBI). In 1939, he was elected to the Baseball Hall of Fame and was the first MLB player to have his uniform number retired.

A native of New York City and attendee of Columbia University, Gehrig signed with the Yankees in 1923. He set several major league records during his career, including the most career grand slams (23) (since broken by Alex Rodriguez) and most consecutive games played (2,130), a record that stood for 56 years and was long considered unbreakable until surpassed by Cal Ripken, Jr. in 1995. Gehrig's streak ended in 1939 after he was diagnosed with amyotrophic lateral sclerosis (ALS), a disorder now commonly referred to as Lou Gehrig's disease in North America. The disease forced him to retire at age 36 and was the cause of his death two years later. The pathos of his farewell from baseball was capped off by his iconic "Luckiest Man on the Face of the Earth" speech at the original Yankee Stadium.
