Hi, a friend of mine was ill for few days for over 104 degree temperature...there was no flu like symptoms..right now after his blood and urine test he is finding occult blood in the urine. Also, he is kind of weak and unable to speak and write properly. He can think but can not put it into words.Whatever he speaks, he can not complete the sentence or pronouces it incorrectly.Like, if he has to say 'medicine', he says it 'mecicine'.Can you suggest me the cause?
