My Grandad has recently been admitted to hospital with a stroke but had come out after 5 days only to go back again 1 week later.

When he went in the first time he had difficulty getting his words out and was very unsteady on his feet.

This time he cannot say hardly any words right at all other than when he gets frustrated he can say 'F@@@ It' very well. When he speaks 99% of his words don't make sense at all and are as if he is speaking an alien language. He can barly stand up and is very emotional at the site of people visiting him.

He had a cat scan on saturday which they had found a spot on his brain. But because the main specialist isn't in until Monday they are very reluctant to say anything other than he most probably will need surgery.
They have now transfered him to a hospital in Romford, UK called Queens Hospital which is supposed to specialise in this sort of thing.

Does anyone have an idea of what it may be as I have no clue what so ever other than a tumor.
