Alan Alda reveals the strange sleep habit that led to his Parkinson’s diagnosis

Alan Alda’s Parkinson’s journey began with a surprising moment that he never expected. Long before many people associate the disease with visible tremors, the beloved actor experienced an unusual incident in his sleep that left him wondering what was happening. While dreaming that he was defending himself against an attacker, Alda imagined throwing a sack of potatoes. But his body followed the dream, and he accidentally threw a pillow at his wife, Arlene.

At first, the incident may have seemed like an unusual dream or an isolated moment during the night. However, Alda later learned that acting out dreams can sometimes be associated with a condition known as REM sleep behavior disorder. During normal REM sleep, the body’s muscles are temporarily relaxed, preventing most physical movements while dreaming. In people with this disorder, that natural protection is impaired, allowing them to move, shout, kick, or even throw objects while asleep.

Alda eventually received his Parkinson’s disease diagnosis in 2015. He shared his experience publicly to help others recognize that the condition does not always begin with the symptoms people commonly expect. Parkinson’s can affect movement, balance, coordination, and other aspects of daily life, but early signs vary from person to person.

Although REM sleep behavior disorder is associated with an increased risk of developing Parkinson’s and certain other neurological conditions, it is important to understand that experiencing this sleep disorder does not automatically mean someone will develop Parkinson’s disease. Anyone who repeatedly acts out dreams, particularly in ways that could cause injury, should discuss the symptoms with a healthcare professional.

For Alda, the diagnosis brought new challenges, but it did not take away his determination to live fully. Known for his memorable performances in MASH\* and The West Wing, he has continued to speak openly about his experiences, helping audiences better understand a condition that affects millions of people worldwide.

One of the most striking aspects of his story is the way he uses humor to cope with everyday frustrations. Alda has described laughing when involuntary hand movements interfere with tasks such as working on his computer. Rather than allowing every difficult moment to become a source of despair, he sometimes finds a way to turn the experience into a joke and share the laughter with Arlene.

Their relationship has been an important part of his journey. The couple first connected through laughter at a dinner table, and their long marriage has continued to provide companionship through life’s unexpected changes. Their story is a reminder that love is not simply about sharing happy moments; it is also about facing uncertainty together, adapting when circumstances change, and finding comfort in the smallest things.

Parkinson’s disease remains a serious and often unpredictable condition, and humor cannot remove every difficulty that comes with it. Yet Alda’s openness demonstrates how honesty, support, and a positive outlook can help people navigate challenging circumstances without allowing a diagnosis to define their entire lives.

His experience also offers an important lesson: sometimes, the body gives us unexpected signals that deserve attention. A strange nighttime incident may have an innocent explanation, but recurring symptoms should never be ignored. Recognizing unusual changes and seeking appropriate medical advice can help people better understand their health.

Through his story, Alan Alda continues to remind people that even when life takes an unexpected turn, connection, curiosity, and laughter can remain powerful sources of strength. His journey is not simply a story about Parkinson’s disease; it is also a story about resilience, lasting love, and the importance of finding moments of joy even when life becomes more complicated.
