The causes of occupational stress can be placed into a broad category of what the main occupational stressor is and a more specific category of what causes occupational stress. The broad category of occupational stressors include some of the following: bad management practices, the job content and its demands, a lack of support or autonomy and ...
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]
In 1620, Johann Jakob Wepfer, by studying the brain of a pig, developed the theory that stroke was caused by an interruption of the flow of blood to the brain. [6] [page needed] After that, the focus became how to treat patients with stroke. [citation needed] For most of the last century, people were discouraged from being active after a stroke.
The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and sometimes a hemorrhagic stroke. [2] Hypertension (high blood pressure) is the most important contributing risk factor for stroke and cerebrovascular diseases as it can change the structure of blood vessels and result in atherosclerosis .

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.
A silent stroke (or asymptomatic cerebral infarction) is a stroke that does not have any outward symptoms associated with stroke, and the patient is typically unaware they have suffered a stroke. Despite not causing identifiable symptoms, a silent stroke still causes damage to the brain and places the patient at increased risk for both ...
Ischemia is one of the leading causes of secondary brain damage after head trauma. [9] Similar mechanisms are involved in secondary injury after ischemia, trauma, and injuries resulting when a person does not get enough oxygen. [5] After stroke, an ischemic cascade, a set of biochemical cascades takes place.
Intracerebral hemorrhage (ICH), also known as hemorrhagic stroke, is a sudden bleeding into the tissues of the brain (i.e. the parenchyma), into its ventricles, or into both. [3] [4] [1] An ICH is a type of bleeding within the skull and one kind of stroke (ischemic stroke being the other).
