Children Health – Causes and Symptoms of Neurodevelopmental Disorder

Neurodevelopment disorder is also known as disorder of neural development or brain development disorder. Physically, it is characterized as impairment of brain or central nervous system. Psychologically, it is defined as a condition of abnormal brain function that effects the children’s emotion, learning ability and memory as they grow. The condition happens in the early year of their life and if not treat, it may inflict their social behaviour, learning ability, etc.

I. Causes

The causes of brain development disorder are still unknown, but many researchers suggest the following

1. Genetic passing through metabolic diseases

The disease is passed through from the parent to the inborn. Genetic and metabolic disorder are hard to diagnosis in the new born. The infant may be look healthy and with no any symptom when they were born, because the disease won ‘t strike until the time when children start to make directed contact with their surrounding environment. The typical cases are

a) Down syndrome

It is known as trisomy 21, is caused by the abnormality of chromosome number 21.

b) William syndrome

It is caused the abnormality of chromosome number 7

c) Fragile X syndrome

d) Rett syndrome

2. Immune disorders

For what ever reason, the immune function becomes over react to certain situations and starts to attackthe brain tissues, leading to abnormal movements of the body, emotional disturbance and obsessive compulsive disorder symptoms.

3. Infectious diseases

Infectious diseases is defined as a type of disease which can transmit from the carrier to other person through one or more of diverse pathways, including physical contact, share food, body fluid, etc.

a) Mealse is one of the infectious disease that can cause subacute sclerosing panencephalitis as resulting of persistence infection by measle virus, leading to brain development disorder (cortical dysfunction).

b) Toxoplasmosis is a parasite disease caused by the protozoan toxoplasma gondii. People contact this type of diseases see their flu like symptoms disappearing within a few week, but for infants who normally have weakened immune system may see the disease progress, leading to encephalitis and severe brain tissues being damaged.

c) Meningitis

Most cases of meningitis is caused by bacteria infection, leading to inflammation, causing severe brain damage to the new born, including deafness.

d) Encephalitis

Encephalitis is another form of virus infectious disease, the new born can contact the virus when pass through an infected birth canal, leading to brain infection. The virus sometimes can stay inactive until the child comes under stress or sickness.

4. Nutritional deficiency

Believe it or not, researchers found that women who have folic acid and iodine deficiency during their pregnancy may cause risk to their babies in contacting neurodevelopmental disorders, leading to severe mental retardation. Excessive intake of both substances above may also cause brain damage as resulting of toxins accumulation in the new born central nervous system.

5. Physical trauma

Most cases of physical trauma is caused by congenital injury, it is happened due to injure as resulting of lack of oxygen to the brain or damage to the brain tissues itself, leading to cerebral palsy that cause permanent physical disability in the child development.

6. Environment toxic

Human have produced over 5000 different environment toxins, including heavy metals such as lead, mercury. If the child is unfortunately to have high levels of heavy metal accumulated in their brain due to detoxification dysfunction of body’s organs, it can cause severe brain damage, leading to impairment of emotional and physical development.

7. Medication

Some researchers found that certain vaccines used to protect the child may contribute to the onset of the disease. One of the vaccine, thimerosal contains 50 time more toxins than the plain mercury, if a infant can not excrete them, it may caused mercury accumulated in the brain, leading to severe brain damage and afflict the child development.

Antibiotic may be another cause of the brain development disorder, as the medication destroy the good bacteria, it causes the inability of the child in absorbing vital minerals, leading to nutritional causes of neuroldevelopment dysfunction

8. Severe deprivation disorder

Researchers found that children were born in a family without loving, caring, nurturing are likely to develop depression and show behavioural retardation.

II. Symptoms

There are many symptoms of neurodevelopment disorder, depending to the diagnosis, but the common symptoms include

1. Delay social development

Children with brain development disorder show little interest to social stimuli, less attention to smile and look at others less often, and respond less to their own name.

2. Communication

Most children do not develop enough natural speech and vocabularies to meet their daily communication needs and are more likely to simply repeat others’ words.

3. Repetitive behaviour

Some children with brain development disorder may have some repetitive behavior such as

Flapping hands, arranging objects in a certain order, involving an unvarying pattern of daily activities and resisting to change.

4. Unusual eating behaviour

5. Motor problems that include poor muscle tone, poor motor planning, and toe walking

6. Insomnia

7. Sensitive to Sound
