Pharmaceutical Exec: Hillary Clinton Has Parkinson’s Disease - "Involuntary movements" and difficulty walking is a form of dyskinesia. According to pharmaceutical executive Martin Shkreli, footage of Hillary Clinton exhibiting bizarre behavior is proof that the presidential candidate is suffering from Parkinson’s disease. Shkreli says that Hillary’s walking difficulties are a “cardinal symptom of Parkinson’s disease” and what is known as “freezing gait”. Shkreli adds that he helped develop a drug to treat the problem.
