阿尔茨海默病（ AD）是一种神经退行性疾病，尽管过去对 AD 治疗的研究有了长足的进步，但是仍然缺乏长期有效的治疗办法。目前，药物治疗和外科手术治疗仅起到缓解 AD 症状的作用，仍不能阻止病情的发展或者恢复受损的神经功能。而细胞替代疗法和基因疗法治疗 AD成为可能，并逐渐成为AD治疗的研究热点，同时也为AD的治疗带来了新的希望。“,”Alzheimer disease(AD) is a neurodegenerative disease.Although the treatment of AD has made great progress, there is still no long-term effective treatment for this disease.At present,drug therapy and surgery can only alleviate the symptoms of AD,which cannot halt the progression or restore the dam-aged neural function.And the stem cell treatment and gene-modified therapy have become technically feasi-ble, and gradually become a focus in the therapeutic strategies for AD , which has brought hope for the treatment of AD.
