Retrograde amnesia vs anterograde amnesia11/19/2023 This brain network understanding of discrete episodic memory processes has translational implications for developing effective interventions and treatments for patients with memory disorders. Answer: Retrograde amnesia is a loss of memories that have been already formed, while anterograde amnesia is an inability to form new memories. Overall, this thesis work contributes to understanding the neural basis of episodic memory by elucidating discrete encoding and retrieval functions impacted in anterograde and retrograde amnesia. Unlike a temporary episode of memory loss, called transient global amnesia, amnesia can be permanent. Our findings shed light on the specific brain networks contributing to anterograde and retrograde amnesias and provide insights into potential intervention targets for patients with memory disorders. Or inflammation may be a result of an autoimmune reaction to cancer somewhere in the body. The major difference between these 2 is that individuals with anterograde amnesia experience difficulty gaining new experiences after the beginning of amnesia but on the other hand. By knowing what amnesia is now let us know more about its types. Brain inflammation, which may be due to an infection with a virus such as herpes simplex virus. Retrograde Amnesia VS Anterograde Amnesia. ![]() Possible causes of neurological amnesia include: Stroke. We also employed lesion network mapping to localize functional and structural brain networks underlying anterograde and retrograde amnesias, lending insight into dissociable processes for encoding and retrieving episodic memory in humans. Amnesia caused by brain injury or damage is known as neurological amnesia. ![]() In this thesis, we used brain lesion analysis to identify differential brain structures associated with anterograde and retrograde amnesias. We classified amnesia cases into three categories according to the severity of memory loss: predominately anterograde amnesia, predominately retrograde amnesia, and proportionate anterograde and retrograde amnesia.Īdvances in neuroimaging techniques have enabled us to locate and segment brain lesions with research-grade accuracy and answer questions about human brain disease and symptoms. Retrograde amnesia: In some ways the opposite of anterograde amnesia, retrograde amnesia is when a person cannot remember events that occurred before their trauma, but they can remember what. Abstract This thesis investigates lesion location and lesion network analyses in anterograde and retrograde amnesia using a systematic review of amnesia case reports and case series in the published peer-reviewed medical literature.
