About 3.0 million deaths resulted from ischemic stroke while 3.3 million deaths resulted from hemorrhagic stroke. [12] About half of people who have had a stroke live less than one year. [2] Overall, two thirds of cases of stroke occurred in those over 65 years old. [19]
The other 15% are hemorrhagic, or the bleeding type. "One of the feared complications of stroke is cerebral edema, or brain swelling," Tan said, adding that usually occurs a few days after the stroke.
It accounts for 50% of all dementias in Japan, 20% to 40% in Europe and 15% in Latin America. 25% of people with stroke develop new-onset dementia within one year of their stroke. One study found that in the United States, the prevalence of vascular dementia in all people over the age of 71 is 2.43%, and another found that the prevalence of the ...
The incidence of post-stroke depression peaks at 3–6 months and usually resolves within 1–2 years after the stroke, although a minority of patients can go on to develop chronic depression. The diagnosis of post-stroke depression is complicated by other consequences of stroke such as fatigue and psychomotor retardation – which do not ...
The incidence of intracerebral hemorrhage is estimated at 24.6 cases per 100,000 person years with the incidence rate being similar in men and women. [7] [8] The incidence is much higher in the elderly, especially those who are 85 or older, who are 9.6 times more likely to have an intracerebral hemorrhage as compared to those of middle age. [8]
Spinal cord stroke is a rare type of stroke with compromised blood flow to any region of spinal cord owing to occlusion or bleeding, leading to irreversible neuronal death. [1] It can be classified into two types, ischaemia and haemorrhage, in which the former accounts for 86% of all cases, a pattern similar to cerebral stroke.
Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
Survival rate is a part of survival analysis. It is the proportion of people in a study or treatment group still alive at a given period of time after diagnosis. It is a method of describing prognosis in certain disease conditions, and can be used for the assessment of standards of therapy. The survival period is usually reckoned from date of ...
