It causes severe seizures, which are often frequent and hard to control. A minority might have seizure control with medicines, but most will need removal or disconnection of the affected hemisphere as the best chance. Uncontrolled, they often cause progressive intellectual disability and brain damage and stop development. [3]
Gerstmann syndrome is a neurological disorder that is characterized by a constellation of symptoms [1] that suggests the presence of a lesion usually near the junction of the temporal and parietal lobes at or near the angular gyrus. Gerstmann syndrome is typically associated with damage to the inferior parietal lobule of the dominant hemisphere ...
The most common cause of asemia is brain damage, such as a stroke or a brain tumor. [4] Other possible causes include Alzheimer's disease and infection. [4] Roger Wolcott Sperry, through his research of split-brain patients, had found out that the human brain lateralizes functions, meaning that the two hemispheres of the brain have different functions.

Aphasia can also sometimes be caused by damage to subcortical structures deep within the left hemisphere, including the thalamus, the internal and external capsules, and the caudate nucleus of the basal ganglia. [44] [45] The area and extent of brain damage or atrophy will determine the type of aphasia and its symptoms.
Apraxia is a motor disorder caused by damage to the brain (specifically the posterior parietal cortex or corpus callosum [1]), which causes difficulty with motor planning to perform tasks or movements. The nature of the damage determines the disorder's severity, and the absence of sensory loss or paralysis helps to explain the level of ...
Callosal syndrome, or split-brain, is an example of a disconnection syndrome from damage to the corpus callosum between the two hemispheres of the brain. Disconnection syndrome can also lead to aphasia , left-sided apraxia , and tactile aphasia, among other symptoms.
“After 30 minutes, seizures cause brain damage. So he was likely getting one week’s worth of brain damage already out of the gate. And it’s possible that he was having seizures in utero and ...
TMoA is generally characterized by reduced speech output, which is a result of dysfunction of the affected region of the brain. [1] 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 ...
