The entertainment industry is mourning the loss of one of its most beloved stars, Billy Miller, who passed away on September 15, 2023.

The actor, best known for his roles in General Hospital, The Young and the Restless, and All My Children, was 44 years old.

According to his publicist, Miller died of complications from a neurological disorder called progressive supranuclear palsy (PSP), which affects the brain and causes problems with balance, movement, vision, speech, and cognition.

Miller had been diagnosed with PSP in 2021 and had been undergoing treatment ever since.

Miller’s fans and colleagues have been expressing their shock and sadness over his death on social media, remembering him as a talented, generous, and kind-hearted person who always brought joy and laughter to everyone around him.

Billy Miller Death Cause: How Did The Actor Die?

According to Monaco, Billy Miller died on September 16, 2023, after suffering a stroke.

Miller’s publicist also confirmed that the actor died at his home in Los Angeles, surrounded by his family and friends.

He had been battling PSP for two years, a condition that has no cure and gradually worsens over time.

PSP is a rare degenerative brain disease that affects about 20,000 people in the United States, according to the National Institute of Neurological Disorders and Stroke.

It is caused by the accumulation of abnormal protein deposits called tau in certain brain areas that control movement, balance, coordination, eye movement, speech, and behavior.

Monaco wrote on Instagram: “My heart is broken. I am at a loss for words. You were my brother, my partner, my best friend. You made me laugh harder than anyone else.”

“You were a brilliant actor, a generous soul, and a loyal friend. You were taken from us way too soon. I will miss you every day for the rest of my life. Rest in peace, Billy. I love you.”
