A recent article by a team of international experts on multiple sclerosis (MS) underscores the importance of expanding the knowledge base about the hippocampus in order to better understand the genesis of cognitive deficits and develop new treatment strategies.
The article, “The hippocampus in multiple sclerosis”, was published in The Lancet Neurology 2018;17:918-926.
The burgeoning field of neuroimaging has fueled cognitive research in MS, including details of the involvement of the hippocampus and associated changes in cognition, as well as the effects of different types of interventions. Techniques such as magnetic resonance imaging (MRI), functional MRI, and diffusion tensor imaging are yielding fundamental in-vivo information about hippocampal pathology and links with clinical manifestations. The authors examine the literature on neuroimaging of the hippocampus in MS, including studies of focal lesions, structural abnormalities, atrophy, and abnormalities of functional connectivity. There is growing evidence that the hippocampus can be modified by aerobic exercise and memory retraining, suggesting the potential for the development of effective cognitive rehabilitative strategies.
