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.
For example, in a gap detection test, subjects with egocentric hemispatial neglect on the right side often make errors on the far right side of the page, as they are neglecting the space in their right visual field. [21] The next range of neglect is "allocentric" neglect, where individuals neglect either their peri-personal or extrapersonal space.
It displays a combination of cerebellar and motor symptoms, including weakness and clumsiness, on the ipsilateral side of the body. [4] It usually affects the leg more than it does the arm; hence, it is known also as homolateral ataxia and crural paresis. The onset of symptoms is often over hours or days.
The dominion of right-sided abdominal pain in omental infarction has been attributed to right segmental infarction as a result of the tenuous blood vessels in this part of the omentum as well as its longer size and higher mobility in comparison to the left side which subjects it to torsion. Obesity is a known risk factor for omental infarction.
Brain stem - Tetraparesis, facial weakness, decreased level of consciousness, gaze paresis, ocular bobbing, miosis, or autonomic instability; Cerebellum - Ataxia, usually beginning in the trunk, ipsilateral facial weakness, ipsilateral sensory loss, gaze paresis, skew deviation, miosis, or decreased level of consciousness
Todd's paresis (or postictal paresis/paralysis, "after seizure") is focal weakness in a part or all of the body after a seizure. This weakness typically affects the limbs and is localized to either the left or right side of the body. It usually subsides completely within 48 hours. Todd's paresis may also affect speech, eye position (gaze), or ...
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.
Focal neurological deficits may be caused by a variety of medical conditions such as head trauma, [1] tumors or stroke; or by various diseases such as meningitis or encephalitis or as a side effect of certain medications such as those used in anesthesia. [2] Neurological soft signs are a group of non-focal neurologic signs. [3]
