Current status: Cognitive dysfunction is not taken seriously by families In China, there are about 2 million new cases of cerebrovascular disease each year, and about 1.5 million deaths from cerebrovascular disease each year, with about 6-7 million patients surviving. About 90% of stroke survivors have cognitive dysfunction, including cognitive decline, executive dysfunction, depression, apathy, and decreased emotional intelligence. Statistics show that about 75% of stroke patients have long-term cognitive dysfunction, 71% of stroke patients have executive dysfunction, 57% of stroke patients have emotional apathy, and 63% of stroke patients have post-stroke depression. Post-stroke cognitive dysfunction can seriously affect patients’ quality of life, delay recovery from neurological deficits and cognitive function, increase the risk of death and recurrence of stroke, and mild cognitive dysfunction can progress gradually to vascular dementia. It is of concern that despite the high rate of cognitive dysfunction in stroke patients, most of the time, families still focus on physical dysfunction such as muscular paralysis and aphasia, but know little about cognitive dysfunction and are seriously unaware of it. Many post-stroke patients have serious psychological problems and even suicidal tendencies, but they are unable to get the understanding and attention of their families. Diagnosis: cognitive screening can help to detect the condition Currently, the assessment of cognitive-emotional impairment in stroke survivors is still in its infancy in China, and a significant number of “hidden” patients with cerebral infarction but no obvious symptoms have never been screened for cognitive-emotional impairment. In fact, targeted professional cognitive-emotional screening is essential to identify such hidden patients. Many patients with “mini-strokes” have no obvious symptoms, only mild numbness and unresponsiveness in the arms and legs. Early cognitive screening can help detect cognitive changes in these patients. In addition, patients with “multiple lacunar cerebral infarction” are often missed due to the lack of obvious symptoms and are usually detected during physical examinations. In fact, due to the multiplicity of lesions, patients with multiple lacunar cerebral infarction are more prone to cognitive dysfunction than other types of patients, and recurrent vascular cognitive impairment can eventually lead to vascular dementia, so early cognitive screening is very important for this group of patients. Reminder: Screening is needed for three groups of people Cognitive function includes language, numerical ability, motor planning and control, memory, attention and executive function. In stroke patients, common cognitive impairments include perceptual impairment, executive function impairment, and attentional impairment (including controlling and maintaining attention). However, in practice, stroke patients often have verbal disability and spatial attention difficulties, which cannot be reliably assessed by virtue of general cognitive tests, resulting in selective bias in experimental data. Therefore, people with possible cognitive impairment should be promptly screened for cognitive function at a specialized institution. So, who needs to be screened for cognitive impairment? The following three groups of people need to be screened: 1, people with high risk factors for cerebrovascular disease, such as hypertension, hyperlipidemia and diabetes, obese people, people with a long history of smoking or a family history of cerebrovascular disease. 2.People with aura of cerebrovascular disease, including vertigo, sudden transient limb numbness, weakness, aphasia and blindness, etc. 3.People who have had a substantial cerebral infarction.
