In donated brains from people with MS, shrinkage in a deep brain area was linked to damaged nerve connections and changes in immune cells.
Researchers examined donated brains from 13 people with MS and 13 people without MS. They studied the thalamus (a deep brain area) using scans and tissue tests. Some parts of this area had shrunk more than others in the MS brains. Shrinkage was linked to changes in nearby nerve connections and immune cells in the brain. Loss of the nerves’ protective covering was not linked to shrinkage, and researchers found no overall loss of connections between nerve cells.
This study examined brain tissue donated after death by people with and without MS. It looked at why a deep brain area shrinks in MS. The findings suggest that damage to connected nerve pathways may be part of that picture. Changes in the brain’s immune cells were also linked to shrinkage in one part of the area. The study did not link shrinkage there to loss of the nerves’ protective covering.
You should know this study used donated brain tissue, not tests in living people. The researchers examined tissue from 13 people with MS and 13 people without MS. These links do not show what caused the shrinkage or whether a treatment could prevent it.

Read MoreWhether you’ve recently been diagnosed with Multiple Sclerosis (MS) or are seeking to broaden your understanding of this complex, neurodegenerative disease, navigating the latest research can feel overwhelming. Studies published in respected medical journals like Acta neuropathologica often range from early-stage, exploratory work to advanced clinical trials. These evidence-based findings help shape new disease-modifying therapies, guide symptom management techniques, and deepen our knowledge of MS progression.
However, not all research is created equal. Some clinical research studies may have smaller sample sizes, evolving methodologies, or limitations that warrant careful interpretation. For a more comprehensive, accurate understanding, we recommend reviewing the original source material—accessible via the More Details section above—and consulting with healthcare professionals who specialize in MS care.
By presenting a wide range of MS-focused studies—spanning cutting-edge treatments, emerging therapies, and established best practices—we aim to empower patients, caregivers, and clinicians to stay informed and make well-informed decisions when managing Multiple Sclerosis.
