铝是否为老年性痴呆症(Alzheimer’sdisease)的病因本已是探讨及争论的课题。老年性痴呆症患者脑内的铝含量较其他患者明显增高,但也有研究者认为这增高仅属偶然。在英国和法国某些地区,饮水中铝浓度较高,老年性痴呆症的发病率也有所增高。新近在加拿大安大略卫生部会议上,有报告称患者注射去铁胺(desferroxamine)以排除铝,可防止铝对细胞的非可逆性损害。将48名老年性痴呆症患者分为两组试验,一组注射去铁胺,一组不给药。去铁胺可与铝结合。经过二年以后,不给药组病情迅速恶化,有的患者死亡,有的必须住院;而给药组仍能自己料理生活,并与他人交往。这结果进一步说明铝与老年性痴呆症的联系。可能由于遗传 Whether or not aluminum is the cause of Alzheimer’s disease has been the subject of debate and debate. Aluminum content in patients with Alzheimer’s disease was significantly higher than other patients, but some researchers think that this increase is only by chance. In some parts of the UK and France, drinking water has a higher aluminum concentration and an increased incidence of Alzheimer’s disease. At a recent Ontario Health Department meeting in Canada, there was a report that patients were injected with desferroxamine to exclude aluminum, preventing irreversible damage to the cells by aluminum. Forty-eight patients with Alzheimer’s disease were divided into two groups: one group received deferoxamine, and the other group did not. Deferoxamine can be combined with aluminum. After two years, the patients in the non-medication group were deteriorating rapidly, some patients died, and others had to be hospitalized. The medication group was still able to handle their own life and deal with others. This result further illustrates the link between Al and Alzheimer’s disease. May be due to genetic
