Former talk show host Wendy Williams was diagnosed with aphasia and dementia last year, according to her care team.

The announcement on Thursday came “after careful consideration, not only to advocate for understanding and compassion for Wendy, but to raise awareness about aphasia and frontotemporal dementia.” Aphasia is a condition that deteriorates language and communication abilities, while dementia progressively weakens cognitive ability and behavior. Williams, 59, left fans speculating for a long time that something was amiss as she hosted her own show, which the announcement addressed.
