What is it about?

Memory impairment occurs often in people with multiple sclerosis. Whether forgetfulness is due to poor encoding, retention, or retrieval is uncertain. Two studies demonstrated that difficulties in learning and retrieving memories account for forgetfulness.

Why is it important?

In demonstrating what accounts for forgetfulness in multiple sclerosis, the study may guide rehabilitation efforts to address the most salient aspects of memory impairment. In doing so, functional outcomes among people with multiple sclerosis may be enhanced more efficiently.


The research literature concerning memory impairment in multiple sclerosis has tended to focus upon encoding or retrieval deficits. This study demonstrates a novel finding, namely that both processes may be diminished among people with multiple sclerosis. It further shows that some people may display impaired encoding, poor retrieval, or both. Memory impairment in multiple sclerosis is unlikely a uniform or homogenous problem.
