Mitchell’s official website elaborates on her condition, saying the artist is speaking and her condition is improving:
Joni did in fact suffer an aneurysm. However, details that have emerged in the past few days are mostly speculative. The truth is that Joni is speaking, and she’s speaking well. She is not walking yet, but she will be in the near future as she is undergoing daily therapies. She is resting comfortably in her own home and she’s getting better each day. A full recovery is expected.
