The ACM Awards don't air until Sunday (April 3), but several awards have already been announced. In a press release issued on Tuesday (March 29), Glen Campbell was acknowledged as a recipient of the Career Achievement Award.

According to the Academy of Country Music, the Career Achievement Award honors artists who have "advanced the popularity and acceptance of country music through their endeavors in the entertainment industry in multiple areas during the preceding calendar year."

Last year, Campbell won a Grammy Award for Best Country Song for "I'm Not Gonna Miss You" and was also nominated for Best Original Song at the 2015 Academy Awards. The iconic song was featured in a 2014 documentary on his life, also titled I'm Not Gonna Miss You, which followed Campbell's farewell tour and struggle with Alzheimer’s disease.

Campbell's wife recently revealed that the country legend has lost his ability to speak.

“He’s healthy, he’s content,” she shares with WTSP news in Tampa Bay, Fla. “He’s lost most of his ability to communicate verbally. He has severe aphasia, but he still understands the universal language of smiles and kisses, and he enjoys food.”

She adds: “We just trust that God has a purpose for everything that we face in our lives, and we just love each other through whatever we’re going through. Alzheimer’s is a disease that affects the whole family.”

Throughout his six decades in the music business, Campbell has sold 45 million records. He is well known for his blend of country and pop on songs like “Gentle on My Mind,” “By the Time I Get to Phoenix,” “Wichita Lineman” and “Rhinestone Cowboy.”

Past recipients of the Career Achievement Award include John Anderson, Vince Gill, Faith Hill, Toby Keith, Tim McGraw, Ronnie Milsap, Johnny Paycheck, Carl Perkins, Reba, Kenny Rogers and Alabama.
