【摘要】:阿爾茨海默病(AD)俗稱老年性癡呆,是一種神經(jīng)退行性疾病。近年來,在人群中的發(fā)病率呈逐年增高的趨勢,隨著國內(nèi)社會老齡化的進(jìn)展,AD的患病人群也在不斷增加,需要引起廣泛的重視。 AD以記憶功能和認(rèn)知功能障礙為主要臨床表現(xiàn),具有起病緩慢,前期癥狀不明顯等特點(diǎn),這對臨床疾病的早期診斷帶來了很大的困難。盡管在1907年就有學(xué)者對AD的發(fā)病進(jìn)行了描述,但時(shí)至今日,對于AD的發(fā)病機(jī)制仍沒有一個(gè)足夠的認(rèn)識,使得臨床在AD的診斷及其治療進(jìn)展上也步履維艱。 目前,臨床對于AD確診仍然是依靠臨床表現(xiàn)癥狀和神經(jīng)心理學(xué)評分,由于AD癥狀出現(xiàn)較晚,前期多得不到重視,故臨床確診的AD多數(shù)為中晚期病人。而在病理解剖中發(fā)現(xiàn),AD病人前期通常會出現(xiàn)腦萎縮的征象,尤其是海馬萎縮更為明顯。本研究在進(jìn)行顱腦MRI掃描來觀察和測定AD病人的大腦及海馬區(qū)的改變中,試圖通過與輕度認(rèn)知障礙(MCI)患者對比,來發(fā)現(xiàn)早期AD患者的顱腦特異性改變,,以期達(dá)到早期診斷AD的目的。
[Abstract]:Alzheimer's disease (AD), commonly known as Alzheimer's disease, is a neurodegenerative disease. In recent years, the incidence of Alzheimer's disease in the population is increasing year by year, with the development of aging society in China. The number of AD patients is also increasing and needs to be paid more attention. AD with memory and cognitive dysfunction as the main clinical manifestations, with slow onset, symptoms are not obvious. Although some scholars described the pathogenesis of AD in 1907, there is still not a sufficient understanding of the pathogenesis of AD. It makes the diagnosis and treatment of AD difficult. At present, the clinical diagnosis of AD is still dependent on clinical symptoms and neuropsychological scores. Therefore, the majority of clinically diagnosed AD patients are advanced patients, and in the pathological anatomy of patients with AD usually have early signs of brain atrophy. In particular, hippocampal atrophy is more obvious. This study attempted to compare the cerebral and hippocampal changes of AD patients with mild cognitive impairment (MCI) by craniocerebral MRI scanning. To detect the craniocerebral specific changes in early AD patients, and to achieve the purpose of early diagnosis of AD.
