Linda Ronstadt has Parkinson's disease

Linda Ronstadt has revealed that she is suffering from Parkinson's disease. The 67-year-old singing legend can no longer perform because of her illness.

According to an interview with AARP, Ronstadt was only diagnosed with the neurological condition about 8 months ago. She did, however, suffer symptoms many years before then -- but she blamed her health issues on a tick bite and on shoulder surgery.

The biggest effect of this illness on Linda Ronstadt is her voice. She explains that "no one can sing with Parkinson's disease, no matter how hard you try." At least finding out was a relief. "I couldn't sing," Ronstadt said in her interview, "and I couldn't figure out why. I knew it was mechanical. I knew it had to do with the muscles, but I thought it might have also had something to do with the tick disease that I had. And it didn't occur to me to go to a neurologist."

Now, Ronstadt must use poles to help walk on uneven ground and travels with a wheelchair.

Beginning in the 1960s and 1970s, Ronstadt was one of the leading voices in the folk-rock musical genre. She won 11 Grammy awards, two Academy of Country Music awards and one Emmy award for her work.
