For other normal people, the diagnosis can be done by performing analysis of the family history, some laboratory tests and clinical evaluation. Some of tests that you can expect the doctors to perform include X – rays, magnetic resonance imaging (MRI), computed tomography (CT).

As of today, there is no specific treatment for NPS. The doctors try to focus on the managing symptoms. For eg – If you are suffering from pain in the knee then you can manage it by physical therapy, braces, splints or medications.

Doctors also monitor people suffering from NPS for kidney problems. They may advise the patient to pass yearly urine tests to check the status of the kidneys. If anything occurs, then normal medications or dialysis can help solve the issue.
