Hi! I’m an undergrad planning to do research on PPPD. There’s very little awareness of it in my country. If my proposal gets approved, would some of you be willing to participate in an anonymous online questionnaire about living with PPPD? I’d be really grateful for your help! 
welcome to forum - you are an unsolicited poster so I can’t vouch for you but if people wish to engage they are free to do so. Good luck with your research and studies!
