Tag: 18 year old

While 18 is the legal age of majority in most US states, emerging neuroscience shows that the human brain, particularly the prefrontal cortex responsible for decision-making, does not fully mature until around age 25. This highlights why the question, 'is 18 considered mature?', has a complex answer that goes beyond legal status alone.

According to the National Institute of Mental Health, the brain's maturation process can extend well into the mid-to-late 20s. This fact challenges the common assumption that **are 18 year olds fully developed** just because they have reached legal adulthood, highlighting ongoing brain and emotional changes that define this critical period.
