- Deep brain stimulation-related disability rates [ Time Frame: changes of baseline and month 1, month 6, month 12 after surgery ]To assess the effectiveness of deep brain stimulation in the treatment of Alzheimer's disease (AD).
- Clinical Dementia Rating(CDR) score [ Time Frame: changes of baseline and month 1, month 6, month 12 after surgery ]The Clinical Dementia Rating(CDR) is 5-point scale used to characterize six domains (memory, orientation, judgment & problem solving, community affairs, home & hobbies and personal care) of the cognitive and functional performance of the aged (in particular AD patients). Patients are rated on dementia severity: 0 = normal, 0.5 = questionable dementia; 1 = mild dementia; 2 = moderate dementia; 3 = severe dementia.
- The Alzheimer's Disease Assessment Scale cognitive subscale (ADAS-Cog) [ Time Frame: changes of baseline and month 1, month 6, month 12 after surgery ]The Alzheimer's Disease Assessment Scale cognitive subscale (ADAS-Cog) scale is widely used for evaluating the severity of AD. ADAS-Cog consists of 12 components including word recall, naming, command, constructional praxis, ideational praxis, orientation, word recognition, remembering test instructions, spoken language ability, word finding difficulty, comprehension of oral language, and attention. The ADAS-Cog assesses multiple cognitive domains including memory, language, praxis, and orientation. ADAS-Cog score ranges from 0-75, with higher scores indicating more severe cognitive impairment.
- Mini-Mental State Examination (MMSE) score [ Time Frame: changes of baseline and month 1, month 6, month 12 after surgery ]Mini-Mental State Examination (MMSE) is one of the most influential cognitive screening tools worldwide. It consists of five dimensions including orientation (10 points), registration (3 points), attention and calculation (5 points), recall (3 points) and language and praxis (9 points). Educational attainment level-related dementia classification: illiterate: 5 points ≤ MMSE score ≤16 points; primary school: 8 points ≤ MMSE score ≤ 20 points; junior high school and above: 10 points ≤ MMSE score ≤ 24 points.
