Physical assault by aggressive older adults.

this assumption is correct, it would be interesting to investigate the extent to which hypertension contributes to atrophy, increases the likelihood of conversion from mild cognitive impairment to fullblown AD, or complicates the course of established AD. In line with this assumption, it is important that some observational studies have reported that use of antihypertensives decreases the risk of AD (Skoog and Gustafson, 2006). If hypertension is proven to be a significant predictor of hippocampal atrophy, then both primary and secondary prevention of AD could be achieved with anti-hypertentive drugs. A large comparative study involving AD patients with hypertension and hippocampal atrophy and those with no atrophy needs to be undertaken to establish this association further.
