Alzheimer’s disease has occurred in numerous maternal and paternal ancestors of mine, including grandparents, aunts, uncles and cousins (my extended family is rather large). I was quite surprised to find that I am homozygous — I carry two copies of a gene variant — for ApoE₄, which is strongly associated with an increased risk of developing Alzheimer’s disease. About 10 years ago, knowing that I have a high probability of developing Alzheimer’s disease, I began being tested annually by a clinical psychologist for evidence of dementia. I work at a large university and supervise graduate students. So, yes, your colleague needs to be schooled in how to treat his graduate students properly.
