Intelligence is a very important thing for everyone, which determines the starting point of your life. However, hard work and diligence can narrow the gap between the two. But no matter which parent wants their child to have low intelligence, what are the manifestations of intellectual disability in a 2-year-old baby? Let's learn about it together.
Performance of intellectual disability in a 2-year-old baby
1. Excessive sleep makes it difficult to wake up, poor sucking ability, and feeding difficulties.
2. Abnormal crying noise caused by stimulation, with prolonged crying time, sometimes requiring repeated or sustained stimulation to induce crying.
3. It takes 3-4 months to show a smiling expression, with no response to external stimuli and a dull expression.
4. The movements of watching and playing with hands continue to exist after 6 months.
5. After 8 months, there is still frequent drooling and grinding of teeth when awake.
6. Children's physical development lags behind that of healthy children by more than 2-3 months.
7. Delayed language development, unclear pronunciation, etc.
8. Visual development is lagging behind, and eye function is underdeveloped because they do not focus on surrounding objects.
9. Delayed auditory development and lack of response to sound are often misdiagnosed as deafness.
10. Facial expressions are dull, and in some cases, a so-called 'dementia face' may appear.
What are the causes of intellectual disability
1. Mechanical damage and hypoxia to the brain account for 19.6%. Brain injury can be caused by physical or mechanical factors before, after, and during childbirth, such as birth injury and traumatic brain injury. Severe blood loss, anemia, heart failure, pulmonary diseases, neonatal asphyxia, intracranial hemorrhage, as well as cerebral hypoxia after drowning, anesthesia accidents, and sustained seizures during the perinatal period.
2. Social psychological factors account for 8.2%. These children do not have organic brain lesions and are mainly caused by adverse environmental factors such as neuropsychological damage and sensory deprivation, such as severe lack of early appropriate stimulation and education.
3. Infection and poisoning accounted for 12.3%. Infection refers to brain infections before and after death, such as rubella, cytomegalovirus, toxoplasmosis, herpes simplex virus, and various other viral infections. Poisoning includes hyperbilirubinemia, toxemia, lead poisoning, alcohol poisoning, and long-term overdose of drugs such as phenytoin or phenobarbital.
4. Gross brain diseases account for 0.7%. Including tumors, degenerative diseases of unknown origin, neuro cutaneous syndromes, cerebrovascular diseases, etc.
The above is a brief introduction to the manifestations and causes of intellectual disability in two-year-old babies. So parents should observe the development of their babies for a long time after they are born. Any developmental problems can be detected through observation, so that early treatment can be sought.
