"Permanently affected by his kidnapping, Getty suffered from drug and alcohol addiction during the years that followed.[13] In 1981, he drank a Valium, methadone, and alcohol cocktail which caused liver failure and a stroke, leaving him quadriplegic, partially blind and unable to speak.[16][17] Afterwards, he was taken care of by his mother. He eventually sued his father for $28,000 a month to cover his medical needs.[13] He never fully recovered and remained severely handicapped for the rest of his life."
