(Associated Press) – Céline Dion has canceled all her scheduled tour dates through April 2024 as she continues treatment for a rare neurological disorder.

A total of 42 European dates have been canceled, including stops in the Netherlands, France, Belgium, Denmark, Norway, Sweden, Finland, Poland, Czech Republic, Switzerland, Croatia, Germany, Hungary, Austria, England, Scotland and Ireland.

Earlier this year, Dion said stiff person syndrome was causing spasms that affect her ability to walk and sing.

Stiff person syndrome causes rigid muscles and painful muscle spasms, which can be triggered by such things as loud noises or light touch.
