Founded by mother-daughter team Heather and Hannah, Pittsburgh-based Hannahtopia makes its signature NillyNoggin EEG Caps for children and adults undergoing epilepsy testing. Shaped by Hannah’s lifelong experience with severe epilepsy and frequent EEGs, the colorful, washable caps are designed to make the procedure feel less stressful while covering the wires and leads. Hannahtopia manufactures the caps in Pittsburgh, Pennsylvania, and makes them in the USA.
