研究目的:

1. 探究术前数字化认知训练能否降低老年患者术后谵妄(POD)发生率。 2. 评估认知训练对患者术后短期及长期认知功能的改善作用。 3. 利用多模态脑功能监测(高密度EEG、fMRI/DWI)揭示认知训练预防POD的神经机制  

Objectives of Study:

1. To investigate whether preoperative digital cognitive training can reduce the incidence of postoperative delirium (POD) in elderly patients. 2. To assess the effect of cognitive training on improvements in patients’ short-term and long-term cognitive function following surgery. 3. To use multimodal brain function monitoring (high-density EEG, fMRI/DWI) to elucidate the neural mechanisms underlying the prevention of POD through cognitive training.

干预措施:

自患者入组时使用手机程序“未来之光”进行术前数字化认知训练。每日训练至少2小时(可分2-3次),覆盖记忆力、逻辑力、反应力、专注力、计算力、想象力六大认知领域,直至手术前一日。

干预措施代码:

Intervention:

From the time of enrolment, patients will use the ‘Light of the Future’ mobile app to undergo preoperative digital cognitive training. They should train for at least two hours daily (which may be divided into two or three sessions), covering six key cognitive domains—memory, logic, reaction time, concentration, calculation and imagination—until the day before surgery.

An independent statistician generated a random number table using PASS 15.0 software and employed block randomisation (with block sizes of 4 or 6), allocating participants to the experimental or control group in a 1:1 ratio. The randomisation sequence was concealed in sealed, opaque, sequentially numbered envelopes.
