Chiari malformation and epilepsy can be connected, but the relationship is complex and not fully understood. Chiari malformation—particularly Type I—involves the downward displacement of the cerebellar tonsils through the foramen magnum, which can disrupt normal cerebrospinal fluid flow and put pressure on the brainstem and spinal cord.
While Chiari malformation is primarily associated with symptoms like headaches, balance issues, and neck pain, seizures have been reported in some patients, especially when the malformation is discovered during evaluations for epilepsy2. However, studies suggest that in many cases, the presence of both conditions may be coincidental rather than causally linked3.
That said, some researchers have observed a higher-than-expected incidence of Chiari malformation in children undergoing imaging for epilepsy, which has reignited debate about a possible connection. In these cases, seizures were often well-controlled with medication, and not all patients required surgical intervention.
If you or someone you know is navigating both conditions, it’s important to work closely with a neurologist and possibly a neurosurgeon to determine the best course of action based on symptoms, imaging, and overall health. Would you like to explore how treatment approaches differ when both conditions are present?
