LOS ANGELES—The management team of Brian Wilson has petitioned to place him in a conservatorship because of his mental decline and the recent death of his wife, Melinda Ledbetter Wilson, who managed his daily life.
The 81-year-old Beach Boys co-founder and mastermind has a “major neurocognitive disorder” and is taking medication for dementia, according to a doctor’s declaration filed with the petition Wednesday in Los Angeles Superior Court.
