Yes, Arnold-Chiari malformation can get worse over time. This is because the malformation is a structural defect of the brain and spine that affects the position of the cerebellum and the base of the skull. As the brain and spine continue to grow, the pressure on the cerebellum can increase, leading to further displacement and worsening of the symptoms.
Symptoms of Arnold-Chiari malformation can include headaches, dizziness, difficulty swallowing, balance problems, fatigue, and ringing in the ears. As the malformation gets worse, these symptoms may become more pronounced and other symptoms, such as tingling in the arms and legs and difficulty speaking, may also appear.
In some cases, medication can help reduce the symptoms associated with Arnold-Chiari malformation and slow the progression of the malformation. However, the only definitive treatment is surgery, which is designed to reduce pressure on the cerebellum and restore normal function. Depending on the severity of the malformation, surgery may involve removing a portion of the skull or vertebrae to create more space for the cerebellum.
In summary, Arnold-Chiari malformation can get worse over time, leading to an increase in symptoms and a decrease in quality of life. Treatment is available, but the only definitive option is surgery.
