**10. Conclusions**

INPH is probably more common that we realise. Due to its reversibility, it is imperative that not only neurologists but other physicians, in particular geriatricians, are more aware of this condition. Although significant progress has been made in our understanding of this condi‐ tion, a unifying theory explaining its pathophysiology is still awaited. Numerous pathophy‐ siological changes have been noted, but it remains unclear which is the cause, effect or epiphenomenon. Given that patients with INPH have pathologies such as VD, AD and PSP, among others, we therefore regard INPH as a multi‐aetiological disorder. For similar reasons, we feel that the role of neurodegeneration should be explored further. Treatment with shunting remains the gold standard. Unfortunately, too often, the condition eventually progresses.
