Alternatively, autobiographical memory loss may result from subtle changes in the temporal lobe which gives rise to temporal lobe epilepsy and to memory problems. The mechanism and etiology of this phenomenon remain controversial, especially as it is impossible to rule out prior subclinical epileptic activity which could be responsible for a ...
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 ...
Anomic aphasia occurring by itself may be caused by damage to almost anywhere in the left hemisphere and in some cases can be seen in instances of right hemisphere damage. [7] Anomia can be genetic or caused by damage to various parts of the parietal lobe or the temporal lobe of the brain due to traumatic injury, stroke, or a brain tumor. [8]
Temporal lobe signs usually involve auditory sensation and memory, and may include: [citation needed] deafness without damage to the structures of the ear, described as cortical deafness; tinnitus, auditory hallucinations; loss of ability to comprehend music or language, described as a sensory aphasia (Wernicke's aphasia)
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).

SD is a clinically defined syndrome but is associated with predominantly temporal lobe atrophy (left greater than right) and hence is sometimes called temporal variant FTLD (tvFTLD). [7] SD is one of the three variants of primary progressive aphasia (PPA), which results from neurodegenerative disorders such as FTLD or Alzheimer's disease .
Frontal lobe epilepsy; Lacunar syndromes; Migraine variants; Posterior cerebral artery stroke; Syncope and related paroxysmal spells; Temporal lobe epilepsy; If the event lasts less than one hour, transient epileptic amnesia (TEA) might be implicated. [2] [30] If the condition lasts longer than 24 hours, it is not considered TGA by definition.
Symptoms will vary according to where the seizure occurs. When seizures occur in the frontal lobe, the patient may experience a wave-like sensation in the head. When seizures occur in the temporal lobe, a feeling of déjà vu may be experienced. When seizures are localized to the parietal lobe, a numbness or tingling may occur.
