Language predicts dementia risk 語言預測失智風險

Language predicts dementia risk 語言預測失智風險


People with superior language skills early in life may be less likely to develop Alzheimer’s disease decades later, research suggests.


A team from Johns Hopkins University studied the brains of 38 Catholic nuns after death. They found those with good language skills early in life were less likely to have memory problems – even if their brains showed signs of dementia damage.

約翰霍普金斯大學團隊,在38名修女逝世後研究她們的大腦。他們發現,早年語言能力好的修女比較不會有記憶問題,即使是她們的大腦出現失智損傷跡象 。

The study appears online in the journal Neurology.


Dementia is linked to the formation of protein plaques and nerve cell tangles in the brain. But scientists remain puzzled about why these signs of damage produce dementia symptoms in some people, but not others.


They divided the women into those with memory problems and signs of dementia damage in the brain, and those whose memory was unaffected regardless of whether or not they showed signs of dementia damage.


And they also analysed essays that 14 of the women wrote as they entered the convent in their late teens or early 20s, assessing them for complexity of language and grammar. The study showed that language scores were 20% higher in women without memory problems than those with signs of a malfunctioning memory.
