[7] [72] Initially, post-stroke individuals have flaccid paralysis. [70] As recovery begins, and progresses, basic movement synergies will develop into more complex and difficult movement combinations. [7] [72] Concurrently, spasticity may develop and become quite severe before it begins to decline (if it does at all).
TIAs and strokes present with the same symptoms such as contralateral paralysis (opposite side of body from affected brain hemisphere), or sudden weakness or numbness. A TIA may cause sudden dimming or loss of vision, aphasia, slurred speech, and mental confusion. The symptoms of a TIA typically resolve within 24 hours, unlike a stroke.
In children, the most common cause is a stroke of the ventral pons. [9]Unlike persistent vegetative state, in which the upper portions of the brain are damaged and the lower portions are spared, locked-in syndrome is essentially the opposite, caused by damage to specific portions of the lower brain and brainstem, with no damage to the upper brain.
The brain is wired contralaterally, which means the limbs on right side of the body are controlled by the left hemisphere and vice versa. [16] Therefore, when Broca's area or surrounding areas in the left hemisphere are damaged, hemiplegia or hemiparesis often occurs on the right side of the body in individuals with Broca's aphasia.
CT scan of the brain showing a massive, prior right-sided ischemic stroke from blockage of an artery. Changes on a CT may not be visible early on. [1] Specialty: Neurology, stroke medicine: Symptoms: Inability to move or feel on one side of the body, problems understanding or speaking, dizziness, loss of vision to one side [2] [3] Complications
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).
