At what age does brain development stop?

In fact, parents all want to know about their children's health status. In the process of taking care of their children, they should also pay attention to various common sense issues, so that when some abnormal conditions are found, they can be discovered in time. For example, many parents need to pay attention to understanding the baby's brain development to a certain age. Now I will give you a detailed introduction. Generally speaking, a child's brain should develop to a certain age.

A child's brain begins to develop at 3-8 weeks of embryonic development, and reaches 80% of an adult's brain capacity at 2 years old, and 90% at 6 years old.

Regarding the nervous system, the brain already has hundreds of billions of neurons, but this does not mean that brain development is complete. After birth, as the baby's external environmental stimuli become richer, connections between neurons continue to form, and the connection points are synapses. The mechanism of learning lies in the change of synaptic capacity. Every neuron has the ability to form new synapses. Babies less than one month old have fewer synapses and lower synaptic density per unit of brain tissue than adults. However, starting in infancy, synapses that are frequently used are consolidated and retained, while synapses that do not receive repeated stimulation are pruned and disappear. The learning process of the brain is based on the synaptic activity of the neural network. The more synapses there are and the greater the density, the stronger the person's learning ability and the higher the level of intellectual activity.

The process of synaptic activity is a sensitive period, during which he will be particularly sensitive to certain abilities. When the critical period arrives, there will be a driving force in the child's heart that drives the child to develop a strong interest in trying or learning specific things. During the "critical period" of a certain ability, this ability develops the fastest and is most easily affected. At this time, giving children rich and appropriate stimulation can achieve twice the result with half the effort. Once the "critical period" is missed, it will take several times the effort to make up for it, or even never be able to acquire it in a lifetime.

I believe that after reading the above content and common sense, everyone should now know at what age a child’s brain development should begin. Only by mastering these contents and common sense can you understand the health status of your baby’s development and be responsible for their health problems. This is something every parent needs to pay attention to.
