MMSE (A) and FAB (B) for each patient over 4 years. (A) The MMSE remained almost unchanged for 4 years in many patients. MMSE showed a significant decrease in cases of dementia with Lewy bodies (DLB) and functional underdrainage associated with weight gain, which we named weight and abdominal pressure induced shunt trouble (WAIST). (B) FAB was also maintained at a high score for 4 years in many patients, but declined significantly in one patient who developed DLB, in two patients with no hobbies and a persistent inactive lifestyle, and in one patient with an underdrainage type of WAIST.
