Ask the doctor, why do I always talk? Come on! I just want to say a word, but my mouth is like a muscle, and it can only be shaken several times.

1. Genetic factors

Some scholars have suggested that some genes are related to stuttering. However, the hypothesis that genes cause stuttering needs further verification. Stuttering is a familial disease in some families, but it has not been ascertained whether this familial disease comes from genetic factors or social factors.

2. Dysplasia of language nerve center or neurophysiological abnormality.

That is, there is something wrong with the nervous system closely related to pronunciation, language understanding and even reading and writing.

Among preschool children, boys stutter twice as much as girls. Moreover, the recovery rate of girls stuttering is higher than that of boys. After the fifth grade (about 1 1 ~ 12 years old), the proportion of male and female stutterers increased to 4: 1. Parents should take their children to see a speech therapist immediately after discovering that their children have stuttering symptoms. They should not delay or sit idly by, hoping that stuttering will recover automatically.

Studies have shown that persistent stuttering in childhood may be due to the abnormality of the left brain, which leads to the disconnection between the cerebral cortex and the areas related to speech ability. Experts point out that because the left brain can't fully grasp the timeliness of making the language area work, the left brain makes up for this deficiency too much, which leads to the inability to speak fluently. When the stutterer's brain is scanned with a magnetic vibrator, it is found that there are some areas with different activities or organizational structures from those of normal speakers (such as the lateralization of the language in the cerebral cortex, the temporal plane in the central advanced auditory area, the abnormal activities in the anterior cingulate gyrus, the anterior insula, the basal nucleus, the cerebellum and the limbic system).

3. Psychological reasons

Such as mental stress, anxiety and stress. Mental factors are the main cause of stuttering.

4. Physiological diseases

For example, children with brain infections, head injuries and infectious diseases such as whooping cough, measles, flu and scarlet fever are also prone to stuttering.

5. Imitation and suggestion.
