I'm hoping someone can help. My dad, who's 78yrs old and usually in excellent health (normal/slightly elevated blood pressure), normal cholesterol, etc - has been suffering from a nagging headache for several weeks. He rubs the sides of his head almost constantly and complains about not being able to 'read the whole word' in books etc - e.g. with the word 'morning' he will only be able to read '...ning'. He has no other symptoms, his balance and gait both fine.
He had and eye test last week and that was normal. He also saw a specialist last Thursday who was just as baffled - he said his eyes are fine apart from a minor cataract (which he's having removed this Thursday). He had a battery of blood tests which came back normal.
My mom (who's a retired nurse) asked the specialist if it could be a TIA (Transient Ischemic Attack) and his eyes suddenly widened and he went to speak to a colleague. They haven't ruled it out, but haven't said that it might be either.
Is there something we are missing?
Your help would be much appreciated!
