Eating more fish is associated with lowering the onset of medical conditions like stroke and dementia a recent study published in the journal Neurology revealed.

Evidence shows that in individuals without stroke or dementia higher fish intake is associated with lower pre-symptomatic or subclinical Cerebrovascular Diseases (CVD), researchers of the study from Bordeaux University found.

The study undertook a cross-sectional analysis of healthy participants without any history of cardiovascular or CVD related hospitalisation of those who underwent brain MRI.

The researchers assessed the fish-eating through a questionnaire and marking of small lesions in brains, an indicator of stroke and dementia using MRI and found that there exists a positive association between fish intake and CVD.

Higher fish intake was associated with lower CVD burden, especially among participants in the 65-69 years age group, the researchers of the study reported. However among the participants of 75 years or more, no significant association was detected, they noted.

If fish is eaten two to three times a week before the onset of CVDs, it may have a beneficial effect on brain health in people under the age of 75, the researchers further noted.

According to another study published in the  Indian Journal of Public Health, the total number of dementia patients in India was estimated to be around 3.6 million in 2020 and could reach as many as 7.5 million by 2040.
