The pattern of memory disturbance and slowed information processing resembled deficits generally observed in subcortical dementias, such as Huntington's disease, but in addition, the patients with multiple sclerosis showed naming difficulties that are usually associated with cortical dementias, such as Alzheimer's disease. The proportion of impaired patients was quite similar for anterograde and remote memory tests and for recall and recognition procedures. The present research was concerned with anterograde and retrograde memory for a. Sudden memory loss is more commonly referred to as amnesia. Read the full article below for the explanation. More than 45% of the patients scored below the tenth percentile. Key words: Hippocampus Thalamus Anterograde amnesia Retrograde amnesia. An athlete can experience two types of post-traumatic amnesia (PTA) after a concussion: anterograde (reduced ability to form new memories) and/or retrograde (partial or total loss of the ability to recall events before injury). The major difference between retrograde amnesia and anterograde amnesia is the following: Retrograde amnesia is the inability to recall past memories while anterograde amnesia is the inability to create new memories. More than 75% of the patients scored below the tenth percentile for controls on the Symbol-Digit Modalities Test, while 61% scored below the tenth percentile on verbal fluency. Anterograde amnesia: Your brain becomes unable to form new memories or store new information after the amnesia-causing event. Deficits were most striking on the Symbol-Digit Modalities Test and the verbal fluency measures, tests that require rapid information processing. There are two main types of amnesia, or memory loss: 1. Although there were marked differences in the extent and severity of cognitive disturbance among individual patients, as a group they were impaired compared with controls on all measures. By contrast, patients with FRA had a sudden onset of memory problems that were characterized by severe retrograde amnesia without associated anterograde amnesia. The persistence of retrograde amnesia is. Retrograde amnesia is the opposite of anterograde amnesia, where a person cannot recall events that occurred before their trauma but can recall events that. Retrograde amnesia can be diagnosed through an MRI scan or CT scan, blood tests, a neurological examination, a cognitive test, or an electroencephalogram, which checks for seizure activity. The performance of 38 patients with chronic progressive multiple sclerosis was compared with that of 26 age- and education-matched controls on a battery of tests of information-processing speed, verbal fluency, naming, egocentric perception, and anterograde and remote memory. A patient with cerebral trauma recovered considerably from the resulting anterograde but not retrograde amnesia.
