If the stroke affects the parts of your brain involved in vision, that can lead to problems noticing things in parts of your visual field, or figuring out exactly what you are looking at.
Localization of function of the thalamus can be illustrated through vascular thalamic amnesia. The damage to the tuberothalmic territory appears to have the most extensive effects in relation to this form of amnesia by affecting functions of arousal and orientation, learning and memory, personality, and executive function.

Since stroke is an essential part of vascular dementia, [13] the goal is to prevent new strokes. This is attempted through reduction of stroke risk factors, such as high blood pressure, high blood lipid levels, atrial fibrillation, or diabetes mellitus. [2] [5] Medications for high blood pressure are used to prevent pre-stroke dementia. [19]
Stroke affecting large portions of the brain can cause significant brain swelling with secondary brain injury in surrounding tissue. This phenomenon is mainly encountered in stroke affecting brain tissue dependent upon the middle cerebral artery for blood supply and is also called "malignant cerebral infarction" because it carries a dismal ...
A new study examines how age-related brain changes could be linked to stroke recovery. Researchers suggest areas of age-related damage to parts of the brain containing white matter may influence ...
Brain injuries can also be the result of a stroke as the resulting lack of oxygen can cause damage to the location of the cerebrovascular accident (CVA). The effects of a CVA in the left and right hemispheres of the brain include short-term memory impairment, and difficulty acquiring and retaining new information. [11]
A person can show one or more of these symptoms during a stroke. If person has a decrease in consciousness, they may be suffering from a stroke in more than one part of the brain or in the brain stem. [12] Symptoms of cerebral infarction can help determine which parts of the brain are affected.
The causes of brain ischemia vary from sickle cell anemia to congenital heart defects. Symptoms of brain ischemia can include unconsciousness, blindness, problems with coordination, and weakness in the body. Other effects that may result from brain ischemia are stroke, cardiorespiratory arrest, and irreversible brain damage.
