Reading Linked to Lower Dementia Risk, Review Finds

A review published Sept. 15 in the journal Psychological Medicine states that reading for pleasure is associated with better cognitive skills, improved mental well-being, and a lower risk of cognitive decline across all ages, according to the study’s authors.

The findings, based largely on observational studies, indicate associations rather than causation, the review noted.

Experts told Healthline that reading may help build cognitive reserve, though they cautioned that more research is needed to determine whether the activity changes the underlying biology of Alzheimer’s disease. The review synthesizes data from childhood through older adulthood, presenting reading as an accessible, low-cost activity with potential brain-health benefits.

Alex Dimitriu, MD, a psychiatrist and sleep medicine specialist who was not involved in the review, told Healthline that reading offers multiple cognitive and emotional advantages. “Reading builds empathy, improves focus, and offers a healthy digital detox,” he said.

“Reading also fires up the imagination and provides a low enough level of stimulation to inspire us to think and feel on our own,” added Dimitriu.

Reading in Childhood and Adolescence

Data from the Adolescent Brain Cognitive Development (ABCD) Study cited in the review associates reading for pleasure during childhood (ages 3-10) with long-lasting cognitive, behavioral, and academic benefits that persist into adolescence. Neuroimaging cited in the review found that reading for pleasure was linked to larger cortical areas and greater volumes in brain regions associated with language and emotional regulation.

Dung Trinh, MD, an internist and chief medical officer of the Healthy Brain Clinic in Irvine, California, who was also part of the review, told Healthline that these structural differences remained significant even after accounting for parental education and household income.

The review notes, however, that reading among children and adolescents is declining, especially among boys ages 11-16 and those from lower socioeconomic backgrounds. A 2025 United Kingdom survey cited in the review identified potential motivators to re-engage young readers: 38.1% said they were more motivated to read when the material related to a favorite TV series or film, 37.1% when it matched a hobby, 30.9% were drawn to an interesting cover or title, and 26.6% valued the freedom to choose what they read.

Nearly half of those who reported low enjoyment of reading still acknowledged its educational value, noting that reading helps them learn new words and new things.

Benefits for Adults and Mental Well-Being

A 2015 Quick Reads survey by The Reading Agency, cited in the review, found that adults reported significant benefits from reading, including increased empathy, personal growth, and stress reduction. Among adults who read for just 30 minutes each week, 64% reported a better understanding of other people’s feelings.

Twenty percent said they began taking better care of their health, and 19% took up a new hobby as a result of reading. Half of the readers noted they became more tolerant of other people’s beliefs, and 17% said they were able to stay calmer during a disagreement.

Survey data cited in the review also found that 74% of adult readers said reading positively affected their mental health and well-being, and 41% said it helped them feel more connected to others.

Reading was identified as one of the most popular stress relievers, with 38% of adults choosing books as their preferred way to unwind, compared to 31% who chose wine and 10% who chose a hot bath. Even six minutes of reading was found to reduce stress by up to 68%, according to the review.

Dimitriu told Healthline that reading offers a rare quiet space in modern life. “The muscles of sustained focus, patience, slowing down, impulse control, and imagination are essential to defining us as human beings, and among our highest qualities,” he said.

Older Adults and Dementia Risk

Evidence from older studies indicates that cognitively stimulating activities such as reading are associated with slower cognitive decline and a reduced risk of dementia in older adults, according to the review. A 2021 study cited in the review found that older adults who read regularly performed better on cognitive tests than those who did not read.

Trinh told Healthline that one theory is that reading helps build cognitive reserve, giving the brain greater resilience as it ages. “While longitudinal studies have found that people who read regularly have lower rates of later cognitive impairment or dementia, more research is needed to determine exactly how much of that relationship is causal and whether reading changes Alzheimer’s biology itself,” Trinh said.

He added that reading should be viewed as one promising component of a broader brain-healthy lifestyle, rather than as a stand-alone treatment or guaranteed way to prevent dementia.

A February 2026 study published in Neurology, reported by NaturalNews.com, found that a lifetime habit of reading, writing, and learning delayed Alzheimer’s disease by five years and mild cognitive impairment by seven years, outcomes that no pharmaceutical treatment has achieved despite billions of dollars in research investment [3].

How to Incorporate More Reading

The review suggests several strategies for incorporating more reading into daily life. Starting small with 15 to 20 minutes a day is recommended.

Joining a book club, either in person at a library or virtually online, can provide social benefits and accountability. Keeping books accessible in visible locations, experimenting with different genres and setting realistic goals are also advised.

Tracking reading progress with an app or a journal can help maintain motivation, according to the review. Choosing materials tied to existing interests or hobbies may also encourage consistent reading habits.

While the evidence remains observational and should not be presented as a guaranteed way to prevent dementia, experts said reading can be a valuable component of a brain-healthy lifestyle.
