Cognitive rehabilitation training generally refers to the training of cognitive dysfunction, such as memory training, attention training and logical thinking ability training. 1. Memory training: Cognitive dysfunction patients are prone to memory loss, and need targeted memory training, such as recognizing cards and words, repeated memory stimulation for patients, so as to improve memory ability. 2. Attention training: For patients with cognitive dysfunction, they may suffer from decreased attention, and usually cannot concentrate, so they can target attention training, for example, by reading stories and looking for the characters and the development of the situation in the stories, so that the patients can gradually improve their ability to pay attention. 3. Logical thinking ability: when cognitive function is abnormal, it will affect the patient’s logical thinking ability, so in the process of rehabilitation training, we need to target the logical thinking ability of training, such as training patients to use blocks to build a certain structure, so as to exercise thinking ability. It is recommended that patients under the guidance of a professional doctor for treatment, do not blindly self-training, to avoid adverse consequences.
