Your Question

Can you help me find information on the diagnosis of secondary (non-genetic) paroxysmal nonkinesigenic dyskinesia?

Our Answer

We have identified the following information that we hope you find helpful. If you still have questions, please contact us.

Are there non-genetic causes of paroxysmal nonkinesigenic dyskinesia?

Yes. Sporadic (non-genetic) causes of paroxysmal nonkinesigenic dyskinesia have been reported in the literature. Non-genetic causes include lesions of the basal ganglia due to multiple sclerosis, tumors, and vascular lesions. In addition, lesions outside the basal ganglia (including those due to penetrating injury) have been reported as causing symptoms similar to those found in paroxysmal nonkinesigenic dyskinesia.[1] In these situations, careful evaluation by a neurologist and neuroimaging (such as MRI) may be necessary for diagnosis.[1]
