Of note, our recent study with 53 PwP (30.2% female; age: 63.79 ± 11.31 years) revealed an association between the presence of PD‐related pain and the severity of dopaminergic deficiency in the caudate nucleus (demonstrated using striatal dopamine transporter visualization with a 123I‐Ioflupane injection and a single‐photon emission computed tomography), further supporting the previously reported involvement of dopaminergic neurotransmission in the modulation of nociceptive information in PwP (Rukavina et al., 2023) (Brefel‐Courbon et al., 2005). The gene discussed is SLC6A3; the disease is Parkinson disease.
