You're welcome. I just read your journal entry on your concern for your brother's children's future, and wanted to reassure you. Thanks to FMRI technology, Alzheimer's research is advancing, just never fast enough for those who are affected. There are some preventive measures; constant learning, playing a musical instrument, speaking multiple languages...but the most important is to keep the mind working. Doing puzzles, belonging to book clubs, engaging in volunteer work. It is sad that her family did not want to admit her condition, because the earlier treatment is started, the more time they have before they worsen into nothingness. While there isn't a cure, there are treatments that are effective. I write for a blog for the elderly, so I'm constantly reading about Alzheimer's research, and my F-i-L had Alzheimer's, so I have that same worry about my own children. Fortunately, my son is a musician, and my daughter speaks numerous languages.
