One local report says Dolores has suffered an ischemic stroke, caused by a blood clot that blocks or plugs a blood vessel in the brain.
This is the most common type of stroke.
Reports say Dolores is resting after receiving mechanical thrombectomy, a technique which involves the removal of a blood clot from the artery through a catheter.
Her family are said to have asked the regional health service to respect her privacy while she remains in intensive care at the hospital.
There has been no comment by any of her four children, but wellwishers have offered the 65-year-old their support on social media.
Wish her well in the comment section below👇👇
