Fellow musicians are reaching out on Twitter to express their support for ailing legendary Canadian folk singer Joni Mitchell.

The Rock and Roll Hall of Famer was placed in intensive care in a Los Angeles-area hospital Tuesday after she was found unconscious in her home. Precise details of her illness have yet to be released.

"She is currently in intensive care undergoing tests and is awake and in good spirits," said a statement on Mitchell's website. "Light a candle and sing a song, let's all send good wishes her way."

Many artists from the music industry posted positive messages for the eight-time Grammy winner on Twitter.

Fellow Canadian musicians, St. Vincent and Ron Sexsmith, also voiced their concerns for the singer-songwriter who hails from Fort Macleod, Alta.

On Tuesday, Los Angeles fire officials said paramedics responded to an afternoon 911 call in Bel-Air, where Mitchell lives. A patient was taken to hospital, but the authorities could not confirm the identity or reveal any details about the patient’s condition.

The 71-year-old admitted in December that she was suffering from a rare condition, Morgellons disease. The mysterious illness is associated with a crawling sensation on or under the skin, and itchy skin rashes or sores that can severely interfere with a person's quality of life.

Mitchell has said that the condition prevents her from performing.

Despite her health, Mitchell released a career-spanning four-disc box set last year, with 53 newly remastered songs.

In her more than 40 years in the music industry, Mitchell has captured eight Grammy Awards, including a lifetime achievement award in 2002.

The Alberta-born star -- who spent the early years of her career playing in small nightclubs in Saskatchewan and Western Canada, as well as busking on the streets of Toronto -- was inducted into the Rock and Roll Hall of Fame in 1997.

Mitchell is also a member of the Canadian Music Hall of Fame and the Canadian Songwriters Hall of Fame.

In 2000, she received a star on Canada's Walk of Fame, and two years later became only the third popular Canadian musician to be appointed a Companion of the Order of Canada.

Mitchell moved to Southern California in the late 1960s, joining a blooming folk scene.

In 1969, Mitchell achieved mainstream success with her second album, "Clouds." Songs such as "Both Sides Now" and "Chelsea Morning," helped Mitchell take home the Grammy for best folk performance.

Her 1971 record, "Blue," was an instant critical and commercial success, thanks to songs like "California," "Blue" and "Carey." The Rolling Stone placed "Blue" 30th on the magazine's list of "500 Greatest Albums of All Time."

Mitchell has released 19 albums over her long-standing and highly successful career.
