The associated autobiographical memory impairment is, however, a more puzzling consequence of medial temporal lobe pathology on this theory. It could be that epileptiform activity originating in the medial temporal lobe has the potential to disrupt the distributed neocortical traces required to maintain detailed autobiographical memories.
The temporal lobe is located beneath the lateral fissure on both cerebral hemispheres of the mammalian brain. [3] The temporal lobe is involved in processing sensory input into derived meanings for the appropriate retention of visual memory, language comprehension, and emotion association. [4]: 21 Temporal refers to the head's temples.
The difference in memory between normal aging and a memory disorder is the amount of beta-amyloid deposits, hippocampal neurofibrillary tangles, or amyloid plaques in the cortex. If there is an increased amount, memory connections become blocked, memory functions decrease much more than what is normal for that age and a memory disorder is ...
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)
For autobiographical memory, the hippocampus, located in the medial temporal lobe, is involved in the encoding of declarative memory (memory for facts and events), while the temporal cortex is involved in the storage of such memory. [21]
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. There ...
The pathophysiology of anterograde amnesic syndromes varies with the extent of damage and the regions of the brain that were damaged. The most well-described regions indicated in this disorder are the medial temporal lobe (MTL), basal forebrain, and fornix. Beyond the details described below, the precise process of how we remember – on a ...
