What is the best natural treatment for nph?

Varies. Surgery with a ventriculo-peritoneal shunt is the best treatment for nph. However, for patients who cannot tolerate surgery, or are very early on in their symptomatology, one could consider physical, occupational and speech (cognitive) therapy. These modalities can teach the patient how to compensate for the symptoms of nph. For example, gait training or balance training.
Shunt. Some patients with normal pressure hydrocephalus respond to a shunt being placed to divert flow of csf; however, many do not, and treatment is just supportive care. There is no natural treatment for this.
