The most common cause of hemiparesis and hemiplegia is stroke. Strokes can cause a variety of movement disorders, depending on the location and severity of the lesion. Hemiplegia is common when the stroke affects the corticospinal tract. Other causes of hemiplegia include spinal cord injury, specifically Brown-Séquard syndrome, traumatic brain ...
Hemiplegia (Greek 'hemi' = Half), is a condition that affects one side of the body. Signs of a hemiplegic migraine attack are similar to what would be presented in a stroke that typically includes sudden severe headache on one side of the brain, weakness of half the body, ataxia and aphasia which can last for hours, days or weeks.
The cause of Todd's paresis has been attributed to the affected cortex being ‘exhausted’ or silenced due to increased inhibition, but these conjectures are not supported. It has been observed that the impairments that follow seizures are similar to those that follow strokes, where for a period of time blood flow to certain areas of the ...
Leukodystrophies are a group of hereditary diseases that are known to cause spastic hemiplegia. Brain infections that cause spastic hemiplegia are meningitis, multiple sclerosis, and encephalitis. [7] The spasticity occurs when the afferent pathways in the brain are compromised and the communication between the brain to the motor fibers is lost ...
FHM can also present with the same signs as benign familial infantile convulsions and alternating hemiplegia of childhood. Other symptoms are altered consciousness (in fact, some cases seem related to head trauma), gaze-evoked nystagmus , and coma .
Middle alternating hemiplegia (also known as Foville Syndrome) typically constitutes weakness of the extremities accompanied by paralysis of the extraocular muscle, specifically lateral rectus, on the opposite side of the affected extremities, which indicates a lesion in the caudal and medial pons involving the abducens nerve root (controls movement of the eye) and corticospinal fibers ...
Spastic cerebral palsy is caused by malformation of or damage to the parts of the brain that control movement. [12] What exactly makes some children susceptible to such brain damage is often unknown but it is believed that cerebral palsy may be the result of causal pathways, or chains of events that cause or increase the likelihood of brain injury. [13]
Weber's syndrome, also known as midbrain stroke syndrome or superior alternating hemiplegia, is a form of stroke that affects the medial portion of the midbrain. It involves oculomotor fascicles in the interpeduncular cisterns and cerebral peduncle so it characterizes the presence of an ipsilateral lower motor neuron type oculomotor nerve palsy and contralateral hemiparesis or hemiplegia.
