When Is Your Brain Fully Developed?

Rates of Brain Development

A person’s brain is not fully developed until their mid to late 20s, as the brain grows in physical size and with the emergence and strengthening of nerve pathways in the brain.

Maturity, judgment, insight, and intelligence develop throughout childhood and young adulthood. Structural brain development during these years enhances learning skills and reasoning abilities—and different life experiences also enrich or disrupt the progression of brain development.

Parts of the brain mature at different rates, and sex hormones can affect brain development between people of different sexes.

Rates of Brain Development

Various parts of the brain grow and mature at varying rates, and life experiences can help promote or inhibit the maturation of certain parts of the brain. The most rapid brain development occurs between the prenatal stages (before birth) and age 8, when nerve pathways develop and become strengthened.

Men vs. Women

The hormonal direction of brain development differs slightly between males and females. These differences impact the rate of growth of different brain regions.

Brain Parts

Research using brain imaging studies has revealed a great deal of information about the functions of different areas of the brain, including defining hundreds of pathways that carry out specific tasks.

How Brain Development Works

Brain development includes several different components that contribute to healthy structure and function. Maturation of the brain accelerates the development of skills, and may also inhibit the ability to learn new skills.

Premature Brain Maturation

Sometimes stressful events can accelerate brain development, potentially reducing neuroplasticity at a younger age.

Brain Development Also Varies by Person

While there are some general patterns of brain development, individuals can differ in how their brain matures.

What Age Is Your Brain the Sharpest?

For many people, intellectual abilities, executive function, social skills, and empathy continue to improve throughout adulthood. Sometimes, illness or abilities can cause a decline in brain skills.

When Does Your Brain Start Aging?

Brain aging doesn’t affect everyone in the same way. Certain health conditions can harm the brain, accelerating age-related shrinking and damaging different parts of the brain.

Conclusion

Enhanced brain functioning involves structural physical growth of the brain, along with the development of brain communication networks. Cognitive and emotional abilities, such as learning, reasoning, self-awareness, self-control, and empathy, can improve as the brain develops with age.

Frequently Asked Questions
