Chiari malformation is a neurological disorder that occurs when the cerebellum, the part of the brain that controls balance, descends into the spinal canal. It is usually diagnosed during childhood, but the exact age of diagnosis depends on the type of Chiari malformation.
Type 1 Chiari malformation is the most common, and is typically diagnosed during infancy or early childhood. It is usually identified through an ultrasound or MRI scan if the child shows any signs of abnormal head or neck shape, or if they experience difficulty with feeding, vomiting, or other physical symptoms.
Type 2 Chiari malformation is more serious and is typically diagnosed in infants or toddlers. It is usually identified through an MRI scan if the child experiences any of the following symptoms: difficulty with breathing, swallowing, or speaking; problems with coordination; and asymmetrical facial features.
Type 3 Chiari malformation is the most severe and is typically diagnosed in older children or teens. It is usually identified through an MRI scan if the child experiences any of the following symptoms: difficulty with coordination, problems with balance and walking, and abnormal head or neck shape.
Overall, the age of diagnosis for Chiari malformation varies depending on the type. Type 1 is typically diagnosed during infancy or early childhood, type 2 is typically diagnosed in infants or toddlers, and type 3 is typically diagnosed in older children or teens.
