Bangkok: Thailand`s Queen Sirikit has been advised rest by her doctors after an MRI examination showed a slight shortage of blood in her brain, the Royal Palace announced on Sunday.
The announcement said the 79-year-old Queen had felt dizziness last morning while exercising and had staggered a little but was still fully conscious.
The doctors found a slight shortage of blood in the cerebellum, but could see no bleeding and treated the Queen by giving her a blood transfusion, the online Bangkok Post paper said adding that the doctors were keeping her under close watch.
The Queen has been advised to suspend all official duties for a period.
Just over a week back King Bhumibol Adulyadej, 84, was found to have slight bleeding in his brain`s outer membrane that caused twitching in his hand.
He is said to have recovered after receiving intravenous medication.
The King, the world`s longest-serving monarch, is Thailand`s most revered figure.
