Vitamin C Deficiency Linked to Brain Decline in Older Adults, Study Finds

Islamabad – A new study has highlighted a significant health risk associated with vitamin C deficiency, suggesting that low levels of the nutrient may negatively affect brain health, particularly in older adults.

Vitamin C is widely known for its role in supporting the immune system and various essential bodily functions. However, recent findings published in the journal PLOS ONE indicate that its deficiency may also be linked to changes in the brain associated with cognitive decline.

The study found that elderly individuals with insufficient vitamin C levels showed brain alterations that are commonly associated with memory loss and cognitive deterioration. Previous research had already suggested that diets rich in vitamin C may help reduce the risk of dementia, but limited data existed on the direct effects of deficiency on brain structure.

Researchers analyzed data from 2,000 participants aged 65 years and above. Brain MRI scans were used to examine regions responsible for memory and cognitive processing, and the results were compared with blood samples measuring vitamin C levels.

The findings revealed that lower vitamin C levels were associated with negative changes in brain regions linked to memory, decision-making, and other daily cognitive functions. Scientists observed a strong correlation between vitamin C deficiency and cognitive decline.

However, researchers cautioned that the study establishes only an association and does not confirm a direct cause-and-effect relationship.

Vitamin C also acts as an antioxidant in the body, helping reduce oxidative stress and inflammation. Researchers believe it may play a protective role in preventing damage to brain neurons caused by oxidative stress.
