Summary
Cognitive impairment in multiple sclerosis (MS) is complex, affecting both gray and white matter. Understanding its evolution requires integrating clinical, imaging, and pathological studies.
Area of Science:
- Neuroscience
- Neurology
- Pathology
Background:
- Cognitive impairment is a significant and often debilitating symptom of multiple sclerosis (MS).
- Recent research increasingly focuses on understanding the multifaceted nature and complexity of MS-related cognitive deficits.
- Neuroimaging and pathological studies are crucial for elucidating the underlying neuroanatomy and pathogenesis.
Purpose of the Study:
- To review the characteristics of cognitive impairment in MS.
- To explore imaging and pathological findings related to the evolution of MS cognitive impairment.
- To discuss the roles of gray and white matter, and their interconnectivity, in MS-related cognitive dysfunction.
Main Methods:
- Review of clinical neuropsychological studies.
- Analysis of radiographic and imaging studies.
- Examination of pathological studies, including post-mortem tissue analysis.
Main Results:
- Cognitive impairment in MS is multifaceted, involving various cognitive domains.
- Both gray matter (cortex, hippocampus, thalamus, basal ganglia) and white matter contribute to MS cognitive deficits.
- Interconnectivity between brain structures is vital for cognitive function in MS.
Conclusions:
- Further research integrating longitudinal clinical, imaging, and pathological data is essential.
- A comprehensive understanding requires correlating in-vivo findings with post-mortem tissue analysis.
- Elucidating the precise mechanisms of MS-related cognitive impairment is critical for developing effective interventions.

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...

Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and...
