Brain injury (BI) is the destruction or ... The results of both cases became a vital verification of the relationship between speech and the left cerebral hemisphere.
Hemispherectomy is a surgery that is performed by a neurosurgeon where an unhealthy hemisphere of the brain is disconnected or removed. There are two types of hemispherectomy. Functional hemispherectomy refers to when the diseased brain is simply disconnected so that it can no longer send signals to the rest of the brain and body.
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]
DAI most commonly affects white matter in areas including the brain stem, the corpus callosum, and the cerebral hemispheres. The lobes of the brain most likely to be injured are the frontal and temporal lobes. [19] Other common locations for DAI include the white matter in the cerebral cortex, the superior cerebral peduncles, [16] basal ganglia ...
Traumatic brain injury is defined as damage to the brain resulting from external mechanical force, such as rapid acceleration or deceleration, impact, blast waves, or penetration by a projectile. [10] Brain function is temporarily or permanently impaired and structural damage may or may not be detectable with current technology. [11]
Hence the right hemisphere is able to compensate for the loss of left hemisphere function, but not vice versa. [9] Neglect is not to be confused with hemianopsia. Hemianopsia arises from damage to the primary visual pathways cutting off the input to the cerebral hemispheres from the retinas. Neglect is damage to the processing areas.
The exact prevalence of porencephaly is not known; however, it has been reported that 6.8% of patients with cerebral palsy or 68% of patients with epilepsy and congenital vascular hemiparesis have porencephaly. [5] Porencephaly has a number of different, often unknown, causes including absence of brain development and destruction of brain tissue.
Brain damage, which is the destruction or degeneration of brain cells, is a common occurrence in those who experience a head injury. Neurotoxicity is another cause of brain damage that typically refers to selective, chemically induced neuron /brain damage.
