I didn't know you are in Europe and yes it is difficult to come all the way. I am sure you can find some doctor who is willing to try but good brain specialists are only few which I learnt the hard way. Still haven't found the good one.
I mean the same thing in stores what you go through. Nowadays I go straight and pick up what I need and try not to process anything which makes me dizzy, lost and tired. Not only that when I talk to some one (even in the phone) gives me headaches and dizziness. so I cannot be around people which greatly affects me mentally. I am pretty confined to my apartment (like a solitary prison).
With memory issues Neuropsychologist will be the best to assess. Not sure anything can be done by any one but altleast they can be more specific which areas you lag. Even I want to go there but I cannot tolerate the grueling process which goes for the whole day.
probably you know the taste (I mean flavor) comes from the smell. you are saying you can taste all fruits and also flavored yoghurts. Interesting. I guess some good specialist may be able to help you.
Check out the other thread where there are lot of sufferers and few got the sense back.
