Linda Ronstadt has Parkinson's disease, a condition that has left her unable to perform.
The 67-year-old singer, who will publish her memoir, Simple Dreams, next month, revealed her debilitating condition Friday in an interview with AARP.
She uses poles to assist with walking on uneven ground has been traveling with a wheelchair since being diagnosed with the neurological disorder.
That was eight months ago, though she began experiencing symptoms, including hand tremors and trouble controlling the muscles that let her sing, years ago.
She attributed her problems to residual effects of a tick bite and shoulder surgery.
