Eric Dane, who played the role of Dr Mark "McSteamy" Sloan, on Grey's Anatomy passed away at the age of 53 after battling with a neurological condition called amyotrophic lateral sclerosis (ALS). His family confirmed the news on Thursday.

Dane spoke about the diagnosis of the disease in April 2025. Also known as Lou Gehrig's disease, in this disease, the nerve cells that control voluntary muscles get attacked, rendering individuals incapable of performing even the most basic functions.

Survived by his wife and actor Rebecca Gayheart and his two daughters, Dane always spoke quite openly about the challenges he faced after the diagnosis of the disease. Through dialogue about his neurological condition, he helped spread awareness about the disease and what all effects it can have on one's body and life. In fact, he worked with organisations that were dedicated to the cause.

He was also part of the  nonprofit groups like I AM ALS and Synapticure to spread awareness. For his contribution to research initiatives and educating people about the disease, he was felicitated as Advocate of the Year by the ALS Network.

Moneycontrol team spoke to Dr Praveen Gupta, Chairman, Marengo Asia International Institute of Neuro and Spine, Gurugram, to understand more about ALS, its cure, symptoms, causes and more.

"ALS is a serious condition that affects nerve cells in the brain and spinal cord that control voluntary muscles used for walking, talking, eating, and breathing. When these nerve cells die, muscles become weak and may lead to paralysis," he shared.

'No means to prevent ALS...'

Dr Gupta says that at present, there are no known effective means to cure ALS. "Scientists have not been able to determine the cause of ALS, and most instances occur randomly without any apparent reason. This means that there are no known measures that can be taken to prevent it, as indicated by medical professionals," he told Moneycontrol.

Dr Gupta concluded by saying that the condition may arise due to some genetic or other unknown factors.

FAQs on amyotrophic lateral sclerosis

Q. What is amyotrophic lateral sclerosis?

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord responsible for controlling voluntary muscles. Over time, it leads to muscle weakness and loss of movement.

Q. Is ALS the same as motor neuron disease?

ALS is the most common type of motor neuron disease. In some countries, the terms are used interchangeably.

Q. What are the early symptoms of ALS?

Early signs may include muscle twitching, weakness in the arms or legs, difficulty gripping objects, slurred speech, or trouble swallowing.

Q. What causes ALS?

The exact cause is unknown. Most cases occur randomly (sporadic ALS), while about 5–10% are inherited (familial ALS) due to genetic mutations.

Q. Who is at risk of developing ALS?

ALS most commonly affects people between the ages of 40 and 70. Men are slightly more likely to develop it than women. Family history increases risk in inherited cases.
