6.Pathogenesis and clinical features of cerebral small vessel disease
International Journal of Cerebrovascular Diseases 2011;19(8):620-624
Cerebral small vessel disease (SVD) is an important subtype of cerebrovascular disease. It is also one of the major reasons for resulting in vascular cognitive impairment or dementia in the elderly. SVD is a small arteriovenous lesion in subcortex caused by a variety of causes, mainly causing subcortical lacunar infarction, white matter damage, microblecds and other pathological changes. There is evidence that vascular endothelial function and blood-brain barrier damage may result in small vessel structures and perivascular changes, which may be the initial factors.of causing SVD. Genetic susceptibility is also one of the risk factors that can not be ignored.
7.Stroke and malnutrition
International Journal of Cerebrovascular Diseases 2010;18(10):764-767
The patients with stroke is often accompanied by malnutrition, its causes include eating less, increased catabolism, and intestinal dysfunction, etc. Malnutrition can not only aggravate the extent of brain damage in patients with stroke, but also increase the incidence of complications, and thus affecting the course and prognosis of stroke. Therefore, correct evaluation of the nutritional status in stroke patients, choosing the appropriate nutrient timing and nutritional support methods have important significance. Among a variety of nutritional assessment methods, the scored Patient-Generated Subjective Global Assessment can quickly identify malnutrition in stroke patients. Early enteral nutrition support, including oral nutritional supplements, nasogastric tube feeding and percutaneous endoscopic gastrostomy, can significantly improve the prognosis in stroke patients. Among them, nasogastric tube feeding is the first choice for nutritional support in stroke patients.
