Cerebellar stroke syndrome is a condition in which the circulation to the cerebellum is impaired due to a lesion of the superior cerebellar artery, anterior inferior cerebellar artery or the posterior inferior cerebellar artery. [1] Cardinal signs include vertigo, headache, vomiting, and ataxia. [2]
Hemiparesis, also called unilateral paresis, is the weakness of one entire side of the body (hemi-means "half"). Hemiplegia, in its most severe form, is the complete paralysis of one entire side of the body.
As the pain subsides, weakness usually appears. In addition, chronicle progressive weakness of one leg suggests a tumor of the spinal cord of the lumbar plexus. Fever is often the first symptom of lumbar plexus paralysis, followed by pain in one or both legs. The pain has an abrupt onset and may occur in a femoral or sciatic distribution.
Pusher syndrome is a condition observed in some people following a stroke which has left them with one side weakened due to hemiparesis. Sufferers exhibit a tendency to actively push away from the unweakened side, thus leading to a loss of postural balance. It can be a result of left or right brain damage.
The left hemisphere is usually responsible for performing language functions, although left-handed individuals have been shown to perform language functions using either their left or right hemisphere depending on the individual. The anterior frontal lobes of the language-dominant hemisphere are essential for initiating and maintaining speech. [1]
Due to brain or nerve damage, the brain is constantly sending action potentials to the neuromuscular junctions on the affected side of the body. Similar to strokes, damage on the left side of the brain affects the right side of the body and damage on the right side of the brain affects the left side of the body.
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).
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]
