Members of Manhattan’s Washington Heights recently participated in a study based on the effects of literacy and dementia. Results showed that reading and writing may help deter the forgetful symptoms compared to not reading and writing. Jennifer J. Manly, the senior writer on the paper, said those who couldn’t read and write developed dementia sooner than those who could and did. After studying almost 1,000 people, even those who learned to read at home but received little or no education developed symptoms later in life. Researchers are now asking an empirical question: can the risk of dementia be lowered with more reading and writing?
