Objective: This article explores the effects of early cognitive training and rehabilitation for patients with cognitive dysfunction in stroke. Methods: Stroke patients have cognitive dysfunction, and the incidence of cognitive dysfunction in stroke patients is six to nine times that of patients without stroke. This article selects 118 patients with stroke in our hospital from August 2017 to August 2019, 42 patients with stroke disorders randomly divided into two groups. Both groups of patients received conventional rehabilitation training, and the observation group performed motion observation therapy in virtual reality equipment based on conventional cognitive training. Analysis of time parameters related to rehabilitation training before and after treatment, and evaluation of standard health effects. Results: After 4 weeks of treatment, the cognitive training time parameters of the two groups were compared. The cognitive reaction time was shorter than that before treatment. After treatment, the scores of cognitive training and rehabilitation effects were significantly lower than those before treatment, and the two scores of the observation group were significantly lower than those of the control group. Conclusion: Stroke patients receive early cognitive training with the support of computer-assisted technology to obtain good rehabilitation results.

Background COPD combined with respiratory failure is very common in intensive care unit (ICU). We aimed to evaluate the current status and influencing factors of delirium in elderly COPD patients with undergoing mechanical ventilation. Methods Patients with COPD combined with respiratory failure and mechanically ventilated who were admitted to the ICU of our hospital were selected. The characteristics of included patients were assessed. Pearson correlation analysis was performed to evaluate the characteristics of patients and delirium. Logistic regression analysis was conducted to identify the risk factors of delirium in elderly patients with COPD combined with respiratory failure undergoing mechanical ventilation. Results A total of 237 COPD combined with respiratory failure patients were included, the incidence of delirium was 21.94%. Pearson correlation analysis indicated that age (r = 0.784), BMI (r = 0.709), hypertension (r = 0.696), APACHE II score (r = 0.801), CPOT (r = 0.513), sedation(r = 0.626) and PaO2 (r = 0.611) were all correlated with the occurrence of delirium (all p < 0.05). Logistic regression analysis indicated that age ≥ 75y (OR 3.112, 95% CI 2.144–4.602), BMI ≤ 19 kg/m2 (OR 2.742, 95% CI 1.801–3.355), hypertension(OR 1.909, 95% CI 1.415–2.421), APACHE II score ≥ 15 (OR 2.087, 95% CI 1.724–2.615), CPOT ≥ 5 (OR 1.778, 95% CI 1.206–2.641), sedation(OR 3.147, 95% CI 2.714–3.758), PaO2 ≤ 75 mmHg(OR 2.196, 95%CI 1.875–3.088) were the risk factors of delirium in elderly patients with COPD combined with respiratory failure undergoing mechanical ventilation (all p < 0.05). Conclusions Delirium is common in patients with COPD and respiratory failure undergoing mechanical ventilation, and there are many related influencing factors. Medical staff should pay more attention to patients with risk factors and take intervention measures as soon as possible to reduce the incidence of delirium.
