On this Day:

On June 21, 1939, New York Yankees announced Lou Gehrig’s retirement after doctors revealed he had amyotrophic lateral sclerosis (Lou Gehrig’s Disease).

Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND) or Lou Gehrig’s disease, is a neurodegenerative disease[a] that results in the progressive loss of motor neurons that control voluntary muscles. ALS is the most common type of motor neuron disease. Early symptoms of ALS include stiff muscles, muscle twitches, and gradual increasing weakness and muscle wasting. Limb-onset ALS begins with weakness in the arms or legs, while bulbar-onset ALS begins with difficulty speaking or swallowing. Half of the people with ALS develop at least mild difficulties with thinking and behavior, and about 15% develop frontotemporal dementia. Most people experience pain. The affected muscles are responsible for chewing food, speaking, and walking. Motor neuron loss continues until the ability to eat, speak, move, and finally the ability to breathe is lost. ALS eventually causes paralysis and early death, usually from respiratory failure.

Most cases of ALS (about 90% to 95%) have no known cause, and are known as sporadic ALS. However, both genetic and environmental factors are believed to be involved. The remaining 5% to 10% of cases have a genetic cause linked to a history of the disease in the family, and these are known as familial ALS. About half of these genetic cases are due to one of two specific genes. ALS and frontotemporal dementia (FTD) are considered to be part of a common disease spectrum (ALS-FTD) because of genetic, clinical, and pathological similarities. The underlying mechanism involves damage to both upper and lower motor neurons; in ALS-FTD, neurons in the frontal and temporal lobes of the brain die as well. 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. The goal of treatment is to improve symptoms. A medication called riluzole may extend life by about two to three months. Non-invasive ventilation may result in both improved quality and length of life. Mechanical ventilation can prolong survival but does not stop disease progression. A feeding tube may help. The disease can affect people of any age, but usually starts around the age of 60 and in inherited cases around the age of 50. The average survival from onset to death is two to four years, though this can vary, and about 10% survive longer than 10 years, and death is usually due to respiratory failure. In Europe, the disease affects about two to three people per 100,000 per year. Rates in much of the world are unclear. In the United States, it is more common in white people than in black people.

Descriptions of the disease date back to at least 1824 by Charles Bell. In 1869, the connection between the symptoms and the underlying neurological problems was first described by French neurologist Jean-Martin Charcot, who in 1874 began using the term amyotrophic lateral sclerosis. It became well known in the United States in the 20th century when in 1939 it affected baseball player Lou Gehrig (leading to his death two years later), and later worldwide, following the 1963 diagnosis of then 21 year old cosmologist Stephen Hawking. However, unlike most individuals with ALS, Hawking managed to survive his illness for another 55 years. The first ALS gene was discovered in 1993 while the first animal model was developed in 1994. In 2014, videos of the Ice Bucket Challenge went viral on the Internet and increased public awareness of the condition (per Wikipedia).

First, a Story:

A guy walks into a bar with a dog and the bartender says “No pets allowed!”

The guy says “This isn’t a pet, he’s my friend and he can talk.”

The bartender is skeptical and demands the guy prove it.

The guy asks the dog “What’s the opposite of ‘soft’?” The dog replies “Rough!”

The bartender remains skeptical and asks for more proof.

The guy asks the dog “What do people put over the top of their house?” The dog replies “Roof!”

The bartender gets annoyed and gives the guy one more chance.

The guy asks the dog “Who is the greatest baseball player of all time? Babe……” The dog replies “Ruth!”

The bartender is fed up and throws them out.

The dog says “Should I have said ‘Lou Gehrig?'”

Second, a Song:

John Oliver talks to Stephen Hawking in the first instalment of Last Week Tonight’s new “People Who Think Good” series. They cover such topics as parallel universes, artificial intelligence, and Charlize Theron. We hope you enjoy this!


Thought for the Day:

“I believe alien life is quite common in the universe, although intelligent life is less so. Some say it has yet to appear on planet Earth.” – Stephen Hawking
