PURPOSE: A tau protein agglomeration detection system is provided to be effectively used in screening treatments for dementia including Alzheimer, as well as a tau protein agglomeration inhibitor by effectively detecting agglomeration of tau protein. CONSTITUTION: Tau protein and a fluorescence protein fraction are linked through a linker peptide in a structure. The tau protein comprises an amino acid sequence of SEQ ID NO:1 or a fraction thereof. The linker peptide comprises an amino acid sequence of SEQ ID NO:3, 4, or 5 or a fraction thereof. A composition for screening a tau protein agglomeration inhibitor includes a plurality of the structures. A composition for detecting tau protein agglomeration includes a plurality of the structures.
