His family confirmed the news in a heartfelt statement, describing their heartbreak and celebrating his life and legacy.

Ace Frehley Cause of Death: First Details Emerge

According to reports from TMZ and Rolling Stone, Ace Frehley was hospitalized in September after suffering a brain bleed caused by a fall in his home studio. The injury was described as life-threatening, and his condition failed to improve over the following weeks. Sources close to the family said doctors placed him on life support, and his loved ones were eventually faced with the difficult decision to withdraw it.

While Frehley’s family has not yet issued a detailed medical explanation, a brain bleed — or intracranial hemorrhage — occurs when blood accumulates between the brain and the skull, cutting off oxygen supply. Cleveland Clinic notes that such bleeds are often triggered by trauma, such as a fall, and their severity depends on the location, size, and timing of treatment. Even with prompt medical care, the condition can be fatal, especially in older adults.

Frehley’s final days were spent surrounded by family and close friends. “We are completely devastated and heartbroken,” his family said in their official statement. “We cherish all of his finest memories, his laughter, and celebrate his strengths and kindness. The magnitude of his passing is of epic proportions, and beyond comprehension.”

Frehley, affectionately known as “The Spaceman,” helped shape the sound and success of KISS from 1973 to 1982, contributing to classic tracks like “Rock and Roll All Nite” and “Detroit Rock City.” After leaving the band, he formed Frehley’s Comet and continued performing and recording music, maintaining a dedicated fan base over five decades.
