Having good communication skills is crucial for a baby's personal development in the future. But some babies always ignore others, entertain themselves in their own world, and look confused when teaching to speak, which is likely to lead to autism. So, what are the reasons for a baby developing autism when they are three years old?
1. Organic damage to the brain may occur, such as injuries at birth, intrauterine asphyxia during fetal development, poisoning, viral infections, etc. Babies caused by such causes are often accompanied by symptoms such as epilepsy and abnormal electroencephalogram. Some even exhibit physical deformities.
2. Autism in a three-year-old baby may also be caused by neuroendocrine disorders and abnormalities in neurotransmitters. The behavior of babies is closely related to neurotransmitters. If there is dysfunction in the hypothalamus, it may lead to autism. This condition presents symptoms such as loneliness and inability to establish relationships with others, and may also be caused by abnormalities in neurotransmitters such as endorphins in the brain.
3. Autism is induced by a combination of multiple causes. In most cases, autism coexists with diseases such as tuberous sclerosis, congenital rubella, and phenylketonuria.
4. In addition, autism may also be caused by cognitive impairment. If a baby has psychological cognitive defects, it is easy for autistic babies to damage their ability to understand others, resulting in insufficient social communication skills, and even seeing others as lifeless objects, often unable to recognize conscious behavior.
