Alzheimer’s-related memory loss is more than just not being able to remember someone’s name. “[We’re talking about] forgetting major events or having a loss of whole episodes,” Dr ...
The neurological cause of psychogenic amnesia is controversial. [5] [7] Even in cases of organic amnesia, where there is lesion or structural damage to the brain, caution must still be taken in defining causation, as only damage to areas of the brain crucial to memory processing is possible to result in memory impairment. [7]
The most prominent symptom of post-traumatic amnesia (PTA) is a loss of memory of the present time. [10] As a result, patients are often unaware of their condition and may behave as if they are going about their regular lives. This can cause complications if patients are confined to a hospital and may lead to agitation, distress and anxiety. [10]
The loss of semantic information in amnesia is most closely related with damage to the medial temporal lobe [15] or to the neocortex. [ 16 ] Some patients with anterograde amnesia can still acquire some semantic information, even though it might be more difficult and might remain rather unrelated to more general knowledge.
Tracy’s lab at the Buck Institute is studying memory loss from Alzheimer’s disease and frontotemporal dementia. “Everybody experiences normal age-related cognitive decline, not just people ...
Memory loss in patients with temporally graded RA strongly follows Ribot's law, meaning that one will experience more memory loss for events closer to the injury or disease onset. [4] This type of RA is commonly triggered in individuals with Korsakoff syndrome due to a combination of long-term alcohol use and Wernicke encephalopathy. [7]
This effect is potentially due to the neuronal loss associated with aging occurring mainly in the frontal lobes. [10] [11] It has been previously noticed that frontal lobe damage can cause source amnesia, so the loss of neurons in this area of the brain associated with aging may very well be the cause of the age-related source amnesia seen. [7]
Issues with episodic memory — memory for events in time or if a person doesn’t remember going shopping, for example — can be a sign of a progressive disorder, but not always.
