Ventricular widening within the normal range usually has no effect on the child, but if the widening is more, it may cause the body to develop hydrocephalus, which may affect the normal life in the future. Normally, a ventricular widening of 10 millimeters is considered normal. Ventricular widening within this range does not require intervention and has no effect on the child’s growth and development. If the widening of the ventricles is around 15 mm, it can be judged as the presence of hydrocephalus, which should be taken seriously in time and may hinder the development of the brain and nerves of the body, and in serious cases, it may cause intellectual developmental disorders. If the result of ventricular widening test appears, it is recommended to consult a doctor in time to clarify the cause of the disease and carry out targeted treatment or therapy to avoid delaying the condition.
