Studies have shown that up to 42% of PD patients are affected by RBD.
Researchers have confirmed the connection between PD and RBD for some time.
In PD patients with RBD, faster motor development and higher risk of cognitive decline are more common.
For PD with cognitive impairment and PD with dementia, RBD has also been shown to be an important early sign.
RBD is also considered a prodromal symptom of PD, which means it can occur before other undesirable symptoms related to this condition occur.
