Nadeesha (age 34) came to my clinic last Tuesday and spoke to me with great concern. Her 5-year-old son Ryan was also clinging tightly to her sari.
"Dr. Priya, Ryan will start preschool next week. But he is incredibly scared of going to a new environment and meeting new people. He follows me around whenever anyone comes to the house. He gets angry and yells at me for even the smallest things. He spends the whole day watching videos on his phone and doesn't go out to play with other children. I'm worried about how he will adjust to school," Nadeesha explained her ordeal.
I chatted with Ryan for a while and explained to Nadeesha: "Nadeesha, Ryan is facing a problem of adaptation to a new environment. A child's brain is like a sponge when he is young. This is called neuroplasticity in medicine. New synapses (connections between nerve cells) in the brain are created or strengthened according to the stimuli and experiences received from the external environment. However, due to the child's continuous addiction to smartphone use and the severe mental stress caused by going to a new environment, the secretion of cortisol (stress hormone) increases in the body. This hinders the development of key parts of the brain such as the hippocampus, which stores memory, and the prefrontal cortex, which helps in planning. Today, let's talk about how to adapt a child to a new environment without harming his brain development."
🚨 Red Flags that require immediate medical attention
Although behavioral or adjustment problems in a child may be normal, if the following symptoms are present, it may be signs of autism or another neurological disorder and should be seen by a developmental pediatrician immediately:
- Failure to respond to name and maintain direct eye contact even by the age of 1 or 2 years.
- Complete refusal to communicate using words or sudden loss of previous language and social skills (regression).
- Self-harming behaviors such as banging your head on the floor or wall, or performing the same action repeatedly in an unusual manner (Repetitive behaviors / Stimming).
- Showing no interest in playing with other children and preferring to be extremely alone.
Neuro-scientific factors that affect a child's adaptive capacity
A child's brain interacts with the outside world with the support of key physiological and nervous systems:
1. Cognitive Processes: The child analyzes the new environment through activities such as Attention, Memory, and Intelligence. This is mainly controlled by the brain.From the prefrontal cortex.
2. Neurotransmitters: Chemicals that transmit messages between brain cells, such as dopamine (which provides motivation) , serotonin (which controls mood) , and oxytocin (which creates affection and bonding), determine a child's social behavior.
3. Mirror Neurons: These special nerve cells in the brain help children learn by watching others and imitating what they do.
Comparing different cases of adaptation to the environment
| Development Division | Adaptation features | Functional area of the brain | The role of parents |
|---|---|---|---|
| Emotional | Being able to control one's anger, fear, and stress. | Amygdala and prefrontal cortex. | Listening to the child's feelings, hugging and showing affection (oxytocin stimulation). |
| Social | Playing and sharing with other children. | Mirror Neurons. | Providing opportunities to play with other children. |
| Executive Functions | Planning, decision-making, and practicing patience. | Prefrontal Cortex. | Solving puzzles, assigning small, age-appropriate responsibilities. |
| Sensory | Getting used to tolerating new sounds, lights, and touches. | Sensory organs and primary nervous pathways. | Take the child outdoors (parks, beaches) and expose them to various natural sensations. |
Do's & Don'ts
| ✔️ Things to do (Do) | ❌ Don'ts |
|---|---|
| Encourage your child by praising his small talents and efforts frequently. | Never give smartphones or tablets to children under 2 years of age (it stunts normal brain development). |
| Provide your child with a good night's sleep (10-12 hours) and nutritious food (rich in Omega-3 and Iron) daily. | Avoid yelling or punishing your child when they make a mistake or have difficulty adjusting to a new situation (this increases the stress hormone cortisol). |
| Before taking your child to a new school or place, mentally prepare them by showing them relevant pictures or books. | Avoid comparing your child with other children (Neurodiversity - each child's brain structure is different). |
❓ Some other questions you may have (FAQ)
Why is play important for brain development in early childhood? ▼
Play is the main way a child explores the world. When playing, the connections between neurons in the brain (synapses) are rapidly strengthened, and problem-solving skills (executive functions) and social communication are developed. This is the main natural stimulus that leads to brain development.
How does screen time affect a child's attention span? ▼
The rapid visual stimuli emitted from phone screens artificially increase the dopamine hormone in the brain. As a result, slow-moving processes in the real world (e.g., reading books, classroom teaching) become boring and unpleasant for the child, which severely weakens the child's ability to maintain attention.
How does stress damage a child's memory? ▼
The hormone cortisol, which is produced when a child is constantly afraid or stressed, inhibits the generation of new nerve cells in the hippocampus, the area where memories are stored. This makes it difficult for the child to remember and learn new things.
How do adverse childhood experiences (ACEs) affect a child's future? ▼
Childhood family conflicts, emotional or physical abuse (ACEs) can permanently sensitize the brain's stress response system. This increases the risk of excessive anxiety, depression, and various physical illnesses as an adult.
