Perisylvian syndrome is a rare neurological disease characterized by damage to the sylvian fissure (lateral sulcus), an area in the brain involved in language and speech. The main symptoms are difficulty chewing and swallowing, low muscle tone in the face and tongue, speech and language development disorders, and epilepsy. These symptoms are ...
Temporal lobe epilepsy is the most common focal onset epilepsy, and 80% of temporal lobe epilepsy is mesial (medial) temporal lobe epilepsy, temporal lobe epilepsy arising from the inner part of the temporal lobe that may involve the hippocampus, parahippocampal gyrus or amygdala. [2] [11] The less common lateral temporal lobe or neocortical ...
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).

This may succeed or accompany temporal lobe (uncal) herniation and subfalcian herniation secondary to a supratentorial mass. [ citation needed ] The pathophysiological mechanism is uncertain [ 7 ] but is probably caused by the displacement of the brainstem stretching and tearing perforating branches of the basilar artery to the pons; venous ...
Intraparenchymal hemorrhage is one form of intracerebral bleeding in which there is bleeding within brain parenchyma. The other form is intraventricular hemorrhage). [1] Intraparenchymal hemorrhage accounts for approximately 8-13% of all strokes and results from a wide spectrum of disorders.
Middle cerebral artery syndrome is a condition whereby the blood supply from the middle cerebral artery (MCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the lateral aspects of frontal, temporal and parietal lobes, the corona radiata, globus pallidus, caudate and putamen.
Symptoms of a mild brain injury include headaches, confusion, ringing ears, fatigue, changes in sleep patterns, mood or behavior. Other symptoms include trouble with memory, concentration, attention or thinking. Mental fatigue is a common debilitating experience and may not be linked by the patient to the original (minor) incident.
Cysts on the left temporal lobe have been associated with psychosis. [13] [14] A left fronto-temporal cyst showed symptoms of alexithymia. [15] Cyst on the right sylvian fissure resulted in new onset of schizophrenia-like symptoms at age 61. [16]
