Since the 1930s, the surface area of a modern human brain has increased by around 15 per cent - meaning brain-related issues may be able to be avoided.
Experts have said that the 'battle to beat dementia' is on the horizon as the human brain has grown larger since the 1930s.
Dr Charles DeCarli, director of the UC Davis Alzheimer’s Disease Research Center said: "Larger brain structures like those observed in our study may reflect improved brain development and improved brain health. A larger brain structure represents a larger brain reserve and may buffer the late-life effects of age-related brain diseases like Alzheimer’s and related dementias."
Dr DeCarli, added: "The decade someone is born appears to impact brain size and potentially long-term brain health Top Health Stories Today For participants born in the 1930s, the average brain volume was 1,234 millilitres, compared to those born in the 1970s of 1,321 millilitres, or about 6.6 per cent greater volume.
The researchers found brain structures such as white matter also increased in size when comparing the two groups.
