ANSWERS AND EXPLANATIONS

---

A) cognitive and/or motor regression, progressive blindness, epilepsy, and intracellular accumulation of autofluorescent material

This answer is correct.

Typical features that are shared among the neuronal ceroid lipofuscinoses (also called Batten disease) are progressive blindness, congitive/motor regression, epilepsy, and intracellular accumulation of autofluorescent material.

Not all patients present with all of these features.
