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]
Watershed stroke symptoms are due to the reduced blood flow to all parts of the body, specifically the brain, thus leading to brain damage. Initial symptoms, as promoted by the American Stroke Association, are FAST, representing F = Facial weakness (droop), A = Arm weakness (drift), S = Speech difficulty (slur), and T = Time to act (priority of intervention).
Right hemisphere brain damage (RHD) is the result of injury to the right cerebral hemisphere. [1] The right hemisphere of the brain coordinates tasks for functional communication, which include problem solving, memory, and reasoning. [1] Deficits caused by right hemisphere brain damage vary depending on the location of the damage. [2]
A stroke on the right side of the brain (especially parietal lobe), in addition to producing a homonymous hemianopsia, may also lead to the syndrome of hemispatial neglect. Transient homonymous hemianopsia does not necessarily mean stroke. For instance, it can constitute the aura phase of migraine.
Hemispatial neglect is a neuropsychological condition in which, after damage to one hemisphere of the brain (e.g. after a stroke), a deficit in attention and awareness towards the side of space opposite brain damage (contralesional space) is observed.
Spitzer’s stroke damaged the right side of his brain, which some scientists identify as important for processing musical pitch patterns. He lost the ability to sing familiar music.
In patients whose brain damage was in the right hemisphere, left limb activation (LLA) was another treatment that proved effective. [12] The theory behind this method of treatment is that any use of the damaged side of the brain will enhance all functions related to the damaged hemisphere and that use of the opposite (healthy) side will only ...
CT scan slice of the brain showing a right-hemispheric ischemic stroke (left side of image). A stroke can be caused by a few different situations, but the basic result is the same. Blood flow to a section of the brain is stopped, which results in rapid depletion of oxygen and other nutrients in the starved section. The starved section of brain ...
