Childhood autism generally has a poor prognosis. However, in recent years, with the improvement of diagnostic ability, early intervention, and quality of rehabilitation training, the prognosis of childhood autism is gradually improving. Some children with childhood autism can reach a normal level of cognition, social adaptation and social skills. The prognosis of childhood autism is influenced by several factors, including: 1. The timing of diagnosis and intervention. Early diagnosis and long-term systematic intervention for children during the period of greatest developmental plasticity (generally before age 3) can maximize the prognosis of the child. For children with mild, normal or near-normal intelligence, early diagnosis and early intervention are especially important. 2. Early verbal communication skills. Early verbal communication ability is closely related to the prognosis of childhood autism, and the prognosis is generally better for those who have good verbal function at an early age (before 5 years old) or before the diagnosis of childhood autism. 3. Severity of the disease and intelligence level. The prognosis of children with autism is greatly influenced by the severity of the disease and the level of intelligence. The more serious the disease, the lower the intelligence and the worse the prognosis; on the contrary, the less serious the disease, the higher the intelligence and the better the prognosis. 4. The presence or absence of concomitant diseases. The prognosis of children with autism is also related to the presence of concomitant diseases. The prognosis of children with autism is poor if they have associated disorders such as fragile X chromosome syndrome, tuberous sclerosis, mental retardation and epilepsy. Current research suggests that early detection, diagnosis and intervention are positively associated with the prognosis of autism in children. It is important to fully understand the factors affecting the prognosis of children and actively take treatment measures to improve their condition and promote their development.
