When Does The Brain Stop Growing?

brain growth

It is largely believed that the human brain hasn't fully developed until the mid 20s. One might expect that a young adult of 18 years would have a mature brain, but this in fact, is not the case. At that age, their brains are still developing. A part of the brain called the "Pre-Frontal Cortex", which is responsible for organization and impulse control, is still partly underdeveloped.

Factors influencing brain maturation include:

  • Environment and heredity
  • Age (10-25 years)
  • Sex hormones (estrogen, progesterone, testosterone)
  • Physical, mental and psychological status
  • Socioeconomic status
  • Sleep 
  • Nutrition
  • Drug abuse (nicotine, caffeine, alcohol)
  • Exercise and meditation

Although brain growth stops at about the age of 25 and might be completed by 30 years , it continues to undergo neural changes as learning and adaptation takes place.
