I have lived in Germany for the past thirty years and have befriended an old German couple. Recently he has been diagnosed with vascular dementia and Alzheimers and is now in a home following a fall. He is 92 and during the war was a prisoner of war in Africa in a British camp. He was treated well and his school boy English proved very useful. He has had progressive difficulty with his speech over the last few months and now in the home is only speaking English and that quite fluently. Does anyone know of anything similar. Does he simply think that he is back in Africa in a British hospital or is the German speech part of his brain so badly damaged that it is easier to speak English. However he doesn't like it when I speak English to him - I should speak German and he replies in English. Any comments or experiences? Thanks
