Meanwhile, a study published in the British Medical Journal, found that even two bottles of wine a week can shrink your brain. They conducted MRI scans on 550 people over a 30-year period, and found surprising results. Only 35 per cent of teetotallers showed shrinkage in the hippocampus, a region associated with learning and memory, over the 30 years. While 65 per cent of those who drank between 14 and 21 units a week showed shrinkage. This overturns previous claims that a drink a day can help ‘protect’ the brain.
