Can Parkinson’s Disease Cause Seizures?
Having a diagnosis of Parkinson's disease (PD) does not directly cause seizures [1]. Nonetheless, there is an association between seizure incidence, epilepsy diagnosis and Parkinson's disease. Thus, the risk factor for having a seizure in PD patients is higher than in healthy individuals, with the risk increasing with every comorbidity [2].
The study from Gruntz et al. from 2018 demonstrates this evidence of this increased seizure risk. Patients with PD had a 1.68x higher risk of experiencing seizures than healthy control participants [2].
There is increasing awareness of seizure risk in neurodegenerative conditions, as identifying seizure risk early on can improve prognosis [3].
