My mom has been diagnosed with Atypical parkinson n psp. She has been having mild symptoms over 3-4 yrs n doctors just kept treating her for depression . Last year there was an MRI done n they diagnosed it as atypical PD. She has frequent falls n her body balance is pretty impaired. I have read over internet there have been no break through what so ever for atypical pd. Are there any clinical trials for psp n atypical PD in India or US.
