Another less common type of inferior temporal lobe damage is prosopagnosia which is an impairment in the recognition of faces and distinction of unique individual facial features. [20] Damage specifically to the anterior portion of the left temporal lobe can cause savant syndrome. [21]
Damage to the inferior left temporal lobe, which is shown in green, is associated with TSA. Transcortical sensory aphasia is caused by lesions in the inferior left temporal lobe of the brain located near Wernicke's area, and is usually due to minor hemorrhage or contusion in the temporal lobe, or infarcts of the left posterior cerebral artery (PCA).

Lateral temporal lobe seizures arising from the temporal-parietal lobe junction may cause complex visual hallucinations. [2] In comparison to medial temporal lobe seizures, lateral temporal lobe seizures are briefer duration seizures, occur with earlier loss of awareness, and are more likely become a focal to bilateral tonic-clonic seizure. [2]
Conduction aphasia is caused by damage to the parietal lobe of the brain, especially in regards to the area associated with the left-hemisphere dominant dorsal stream network. [ 17 ] [ 9 ] The arcuate fasciculus, which connects Broca's area and Wernicke's area (important for speech and language production and comprehension, respectively), is ...
Associative visual agnosias are generally attributed to anterior left temporal lobe infarction (at the left inferior temporal gyrus), [8] caused by ischemic stroke, head injury, cardiac arrest, brain tumour, brain hemorrhage, or demyelination.
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 ...
A lesion affecting one side of the temporal lobe may cause damage to the inferior optic radiations (known as the temporal pathway or Meyer's loop) which can lead to superior quadrantanopia on the contralateral side of both eyes (colloquially referred to as "pie in the sky"); if the superior optic radiations (parietal pathway) are lesioned, the ...
Geschwind syndrome, also known as Gastaut–Geschwind syndrome, is a group of behavioral phenomena evident in some people with temporal lobe epilepsy.It is named for one of the first individuals to categorize the symptoms, Norman Geschwind, who published prolifically on the topic from 1973 to 1984.
