The weakness in a leg following a seizure that persists for 15 hours is called Todd's paralysis or Todd's paresis. This is a temporary neurological condition characterized by weakness, numbness, or altered sensation in part of the body after a seizure. Todd's paralysis typically affects the limbs on one side of the body and usually resolves within 24-48 hours, though it can occasionally last longer. If you're experiencing Todd's paralysis that has lasted 15 hours, you should seek medical attention promptly to rule out other possible causes like stroke or more serious neurological damage. While Todd's paralysis itself doesn't typically require specific treatment beyond rest and monitoring, a healthcare provider needs to evaluate the underlying seizure disorder and adjust anti-seizure medications if necessary. The phenomenon occurs because the intense electrical activity during a seizure temporarily exhausts or inhibits the affected brain regions, leading to temporary dysfunction in the corresponding body parts controlled by those brain areas. Key points to consider include:
- The condition is usually self-limiting and resolves on its own
- Medical evaluation is necessary to rule out other causes of weakness
- Adjustments to anti-seizure medications may be needed to prevent future seizures and associated Todd's paralysis
- There is no direct evidence from the provided studies 1, 2, 3, 4, 5 that specifically addresses Todd's paralysis, but the condition is a recognized complication of seizures. Given the lack of direct evidence, the recommendation is based on general medical knowledge and the principle of prioritizing patient safety and preventing further neurological damage.
