Signs of a stroke can range from a motor deficit, a deviating mouth, an arm that does not rise well, difficulty expressing oneself, visual disturbances or numbness in a limb. They are often lateralized, meaning that they appear only on one side of the body.
Diagnosis of Cerebral Vascular Accident
In a hospital setting, the diagnosis of stroke is completed by brain imaging, which makes it possible to confirm and specify the nature of the stroke (ischemia or haemorrhage).
Magnetic Resonance Imaging (MRI) is the most suitable technique to meet the objectives of imaging in stroke, it allows very quickly in the context of ischemia to locate the area of obstruction of the artery and the extent of the "penumbral zone" in order to adapt the treatment as quickly and as well as possible.
Ischemia in the right hemisphere of the brain leads to paralysis on the left side of the body (left hemiplegia), visual disturbances and difficulty locating in space. Patients have a disorder called hemi-neglect. This is reflected in the fact that patients are no longer aware of the left part of their body and behave as if it did not exist.
If ischemia occurs in the left hemisphere of the brain, then patients have right hemiplegia and speech disorders.
