Translation of neurological in German

So by age twelve, I had decided that I wanted to learn English and I was studying for the United States TOEFL at age twenty. Being bilingual practically from birth, makes speaking languages very easy for me.
We can help each other with these language studies, this is also the main purpose of Vocabulix. I have already got in touch with some other users. I can speak Italian, but my grammar is weak.
Should I call him in August? Will he know who I am? I hope that we will return to Italy in October, then we may take a coffee or a beer together, or we can even go to eat something small.
