Most of the literature does seem to indicate the brain is fully developed by age 25. However, I did find one site that extends brain maturation into the 30's and 40's...
My own personal experience at age 69 is that I think they are all of them wrong. I think the brain continues to mature well into the sixties, and probably beyond. I can do things now I could never have done even ten years ago...much more than just absorbing additional knowledge.
Research just does not address the maturation of the brain accurately yet.
Your brain never stops developing and adapting (with the exception of neurodegenerative disease, obviously). One of the most basic mechanisms is called "long-term potentiation", which is a characteristic of any neuron that is post-synaptic to more than one other neuron. New serotonergic synapses are formed when consolidating a memory (think of it as "copying" from short term to long-term memory). You could actually, at any age, have some region (or possibly even regions) of the cerebral cortex removed (for whatever awful reason) and with some physical/occupational therapy, other areas of your brain would actually start taking over the roles of the missing parts. Hopefully that never happens, but it really speaks a lot towards the neuroplasticity of the human brain.
Brain development is a very different process for girls and boys. It is widely documented that girls' brains mature more quickly than a boys until the maturation process evens out at around 30+ years of age. Also brain development also depends on so many other influences: parental nurture, emotional and physical well being, intrinsic motivation, external stimulus, level of IQ, progress and ability of socialisation, feelings of self worth, happiness, self confidence and self control. All these factors (and more) play an important and ongoing role in the development of one's brain power and intellectual abilities. The progess of brain development can be severely hampered by mental health issues (particularly ongoing depression), poverty and abuse in early childhood, poor diet, lack of exercise (physical and mental), poor education and lack of motivation. There is no hard and fast rule applicable across the board. Genealogy also plays a vital role in how a person's brain and intellect will foster - if a child (male or female) has very intelligent, clever, academic parents the chances that child will be intelligent and academic is very high.

The age that I have been told most often (by therapists and a couple doctors in this field) for full brain development is 23 although it does depend on when you classify the brain as "fully developed". I have heard as high as thirty and as low as 18 (legal drinking age in Alberta) but regardless of when it actually is the brain continually changes throughout one's life.
Well um i have to say you can't say fully developed because all kids have a fully developed brain,but wat you could say is they do they have a smart brain enough to develope tons of information and as always thanks for asking.
