Our brain is more advanced than other primates. The brain is one of the things that separates us from them. 

Firstly, the human brain boasts more neurons in the association cortex. In addition, there are also higher fiber connections in areas of the brain concerned with several human-specialized functions.

These include activities like cognition, reasoning, language, and even tool-making. But one thing we must understand is that the brain develops as we age. This development also stops at a specific age. 

Now, here’s a question regarding the brain’s development. 

When is your brain fully developed?

Brain development spans more than two decades. It starts from when an individual is born until their twenties.  

MRI (magnetic resonance studies) has allowed scientists to decipher how the prefrontal cortex (PFC) matures. The discovery shows that men’s and women’s brains develop fully at different ages. 

While men’s brains don’t develop fully until 25, women’s brains become fully developed at 21.

How Developed Is The Brain At 18?

Physically, many 18-year-olds look like adults. And legally, they’re adults. You can join the military when you turn 18. You can also open a bank account and do several things when you turn 18. 

But when you consider brain development, 18-year-olds shouldn’t be called adults. Why? Their brains are still developing.  

So, why are 18-year-olds called adults? How developed is the brain at 18?

We just mentioned that the brain isn’t fully developed at 18. However, at 18, the brain has hit several developmental milestones.  

Nevertheless, the prefrontal cortex (PFC) of 18-year-olds is still developing. The PFC’s development is important since it concerns social interaction. These include how we assess risks, control impulsive behaviors, regulate emotions, and make long-term plans.

Another important part of the brain is the reward system. This part of the brain keeps growing even after 18. Research suggests it reaches full maturity at 25.

The cerebellum also affects one’s cognitive maturity. But compared to the PFC, the environment has a huge impact on the cerebellum’s development. 

How The Brain Of Adolescents Differ From Adults’ Brain

Diverse changes occur in the brain as we grow from adolescence to adulthood. Now, what are those changes?

As you grow from adolescence to adulthood, the brain loses gray matter. This takes place as neurons and synapses get pruned. 

However, loss of gray matter stops in one’s 20s. But the change doesn’t stop there. Certain brain regions strengthen their connections, while the major nerve track becomes covered with myelin sheath, increasing the brain’s white matter.

The prefrontal cortex develops in adulthood and intelligence peaks from 25 (middle adult) to 60 years. 

So, in a nutshell, an adult’s brain is much more cognitively capable than a teen’s brain. 

10 Simple Ways To Keep The Brain Young 

The brain undergoes several changes as we age. There’s also a high risk of cognitive impairment as people age, which is a sign of aging. 

However, these declines are reversible. In other words, you can make your brain young, helping it to surmount age-related cognitive decline. 

So how can you make the brain young? Follow the tips below. 

#1: Exercises regularly:

Exercise can benefit your body in several ways. For example, you can get rid of back pain with the Back Pain Breakthrough, a 30 seconds morning ritual. The workout is designed to make back pain a thing of the past. 

So, regular exercise is highly beneficial. You can even lose weight and keep fit with the right exercise. 

Additionally, research has shown that using the muscles benefits the mind. Exercise can help improve your cholesterol levels, reduce mental stress, balance blood sugar, and lower blood pressure. And all of these are beneficial to the heart and brain.  

#2: Watch the food you eat:

If you haven’t been focusing your attention on the kind of food you consume, you need to start doing so. It’s no secret that food plays a crucial role in the brain’s health. The right food can improve certain mental tasks, such as concentration and memory. 

So, what can you eat to improve brain health? Consider diets that include fish, nuts, fruits, olive oil (unsaturated oil), and plant-based protein. These can help to lower your risk of dementia and cognitive impairment. 

#3: Improve blood sugar level:

Diabetes can reduce an individual’s quality of life. It can even become life-threatening when one’s blood glucose level remains high. 

Diabetes increases one’s risk of developing dementia. So, if you want to keep your brain in good shape, keep your blood sugar under control. Regular exercise and keeping your body lean can help too. 

#4: Stop abusing alcohol:

Do you find yourself drinking excessively now and then? If yes, you’re messing up your brain’s health. Alcohol abuse can harm your brain. It can increase one’s risk of dementia.

It’s okay to drink alcohol but drink in moderation. You can have one or two drinks daily. 

#5: Improve cholesterol levels:

The health implication of high LDL (bad) cholesterol in the body can be massive. There’s a possibility of increased fatty deposits in the blood vessels. High LDL cholesterol can also increase your risk of dementia. 

Simple changes like regular exercise, eating right, tobacco avoidance, and weight control can help lower LDL cholesterol levels. 


So, when is your brain fully developed? The brain doesn’t fully develop when you become an adult or turn 18. It takes more than two decades for the brain to develop or mature fully. 

Scientists have discovered that the female brain develops faster than the brains of males. While males’ brains develop fully at 25, female brains develop fully at 21. 

We also shared tips to help make the brain young again. They include simple tasks like eating right, exercising regularly, improving blood sugar, alcohol, and tobacco avoidance, including lower LDL cholesterol levels. 

The power of exercise cannot be overemphasized. Exercise can improve your health and make certain conditions better. And using this Back Pain Breakthrough, you can stop back pain that makes you uncomfortable.
