University of Cambridge study links reading to brain structural changes

Researchers from the University of Cambridge have published a review in the journal ‘Psychological Medicine’ detailing how regular reading physically reshapes the human brain through neuroplasticity. Imaging studies indicate that reading for pleasure leads to measurable increases in gray matter volume, particularly in areas such as the angular gyrus, which is responsible for language, learning, and executive control.

In addition to gray matter changes, the research shows benefits to white matter, with increased fiber density facilitating more efficient communication between brain hemispheres. These structural adaptations contribute to a higher cognitive reserve. Long-term data suggests that regular readers face a 33 percent lower risk of developing Alzheimer’s disease.

The benefits extend across the lifespan. Data from the ABCD study, involving over 10,000 adolescents in the United States, shows a correlation between early reading habits and improved attention, working memory, and impulse control. Approximately 12 hours of reading per week is associated with the strongest positive cognitive outcomes and larger cortical surfaces in centers for language and emotion regulation.
