Can anyone explain what Parkinson's related Laryngeal Dysfunction is? I was having problems breathing during sleep (according to my husband) & my doctor ordered a sleep study thinking it was apnea. It came back that I don't snore, very mild apnea (2 central, 2 obstructive, 2 mixed, 7 hypopneas). But, I do I the laryngeal thing & the pulmonologist who read the study said that evaluation with an ENT & close monitoring needed to be done. I have an appt with an ENT in 2 weeks, but I'm worried. BTW, I have early-onset PD, am now 47 and am on 1.5mg Mirapex 3 times daily.
