What condition is characterized by eye closure induced seizures and photosensitivity?

Jeavons syndrome is characterized by eye closure-induced seizures, often referred to as "eyelid myoclonia." In this condition, seizures can be triggered by closing the eyes or exposure to flashing lights, demonstrating a significant photosensitivity. The eyelid myoclonia is distinctive and typically occurs alongside generalized tonic-clonic seizures. This unique presentation helps differentiate Jeavons syndrome from other epileptic syndromes.

The other conditions listed do not share the same defining characteristics. For instance, West syndrome primarily presents as infantile spasms and is associated with developmental regression, while Tay-Sachs disease is a genetic disorder leading to neurodegeneration and does not feature seizure activity or photosensitivity. Rasmussen syndrome involves unilateral brain inflammation leading to severe epilepsy, often affecting one hemisphere, but does not feature the specific eye closure-induced triggers seen in Jeavons syndrome. This highlights why Jeavons syndrome is the correct answer in this context.
