Sir Patrick Stewart has died at the age of 86. The actor, known for his roles in Star Trek and X-Men, passed away on Wednesday at his home in Los Angeles. He was under the care of his wife, Sunny, during his final hours.
A statement released on his social media page on Thursday confirmed the news. The family described his illness as a "brief and poignant journey with Alzheimer's disease and Lewy body dementia." The post noted that he was surrounded by family, friends, and live music. It described his final expression as one of "peaceful ease and reflection." The family said his "invincible grace" left a lasting impression on those who knew him.
The Alzheimer's Society explained that these two conditions are distinct but often co-occur. Alzheimer's disease is the most common cause of dementia in the UK. It damages the brain and affects memory and thinking. According to the organization, about two-thirds of people with dementia in the UK have Alzheimer's. Dementia with Lewy bodies is rarer, affecting roughly one in ten people. Experts believe this second type is often under-diagnosed.
Lewy body dementia is caused by small clumps of protein called Lewy bodies. These clumps form in brain nerve cells. The condition impacts thinking, memory, movement, and mood. It also affects how the body functions. The NHS states that dementia is not a single disease but a collection of symptoms resulting from brain damage. The specific symptoms depend on which part of the brain is affected.
Early signs of dementia can be subtle. The NHS lists common early symptoms as memory loss, difficulty concentrating, and trouble with familiar tasks. People may struggle to find the right words or get confused about time and place. These changes are often mild and progress slowly. Doctors may label this stage as mild cognitive impairment. In some cases, these symptoms do not worsen. In others, they develop into full dementia.
Alzheimer's disease presents with specific markers. Patients often forget recent events, names, and faces. They may ask the same questions repeatedly. Tasks that require planning become difficult. People may feel confused in new places or have trouble with numbers and money. They might also become more withdrawn or anxious. Lewy body dementia shares many of these traits but adds distinct physical signs. Patients may experience fluctuating levels of alertness or confusion. They often see visual hallucinations. Their physical movements slow down, and they may suffer from repeated falls, fainting, and sleep disturbances.
Michelle Dyson, chief executive officer of the Alzheimer's Society, expressed sadness over Stewart's death. She called him an "extraordinarily talented and much-loved actor." Dyson noted that both conditions are progressive. They gradually change how a person interacts with the world. The NHS advises that dementia is not a natural part of aging. It recommends that people speak to a general practitioner sooner rather than later if they notice memory problems or other symptoms.
