Μemory by itself as a function, loses its capabilities with a normal deterioration. However, there are acquired conditions that negatively affect the functions of memory, resulting in dysfunction of its stages. Thus possible damage to the structures of the hemisphere that controls these processes disrupts the comprehension, organization and categorization of the material to be memorized. Patients with damage to these systems will have difficulty remembering because they have not adequately coded the material. Patients with Multiple Sclerosis report short-term memory difficulties in the sense that they have difficulty remembering details of recent conversations and events. Aim: To investigate the memory storage difficulties in Multiple Sclerosis. Materials and Methods: An international literature review was performed on Memory Disorders in Multiple Sclerosis. Conclusion: In patients with Multiple Sclerosis learning deficits are greatly aided by processing speed and working memory. It has been observed that slow mental processing makes it difficult for many patients with Multiple Sclerosis to capture an entire verbal message, especially if it is large, complex, delivered quickly and with external stimuli, such as a noisy environment

Alphanumeric Sequencing involves the alternating recitation of counting and the alphabet. We report data on the use of this measure with two clinical samples of persons with multiple sclerosis, having either the chronic progressive (n = 23) or relapsing-remitting form (n = 52) of the disease. Patients were administered Alphanumeric Sequencing and several other tests of information-processing speed/capacity and short-term memory. Chronic progressive MS patients performed worse than 23 healthy controls on both the speed and error components of the test, while relapsing-remitting patients were worse than 35 controls only on the total time to complete the task. The time score was correlated with several measures of information processing and short-term memory.

A general method, including procedural and computational aspects, for expressing short-term memory span as channel capacity is described. The method is then illustrated on an experiment performed to determine the channel capacity for short-term memory storage of decimal digits of two subjects. Curves representing transmitted information as a function of input information are similar in shape to those obtained in information-transmission experiments on absolute judgment.

Evidence of the association between global cognitive function and mortality is much, but whether specific cognitive function is related to mortality is unclear. To address the paucity of knowledge on younger populations in the US, we analyzed the association between specific cognitive function and mortality in young and middle-aged adults. We analyzed data from 5,144 men and women between 20 and 59 years of age in the Third National Health and Nutrition Examination Survey (1988–94) with mortality follow-up evaluation through 2006. Cognitive function tests, including assessments of executive function/processing speed (symbol digit substitution) and learning recall/short-term memory (serial digit learning), were performed. All-cause mortality was the outcome of interest. After adjusting for multiple variables, total mortality was significantly higher in males with poorer executive function/processing speed (hazard ratio (HR) 2.02; 95% confidence interval 1.36 to 2.99) and poorer recall/short-term memory (HR 1.47; 95% confidence interval 1.02 to 2.12). After adjusting for multiple variables, the mortality risk did not significantly increase among the females in these two cognitive tests groups. In this sample of the US population, poorer executive function/processing speed and poorer learning recall/short-term memory were significantly associated with increased mortality rates, especially in males. This study highlights the notion that poorer specific cognitive function predicts all-cause mortality in young and middle-aged males.
