Long\u2010term levodopa treatment has been associated with PN, due to metabolic disturbances, including vitamin B12 depletion and increased homocysteine levels. Small fiber neuropathy is commonly observed in PD and may precede motor symptom onset. Certain pathogenic variants, known to cause parkinsonian syndromes, have also been linked to peripheral nerve involvement (\n                      <jats:italic>PRKN<\/jats:italic>\n                      ,\n                      <jats:italic>DJ1<\/jats:italic>\n                      ,\n                      <jats:italic>PINK1<\/jats:italic>\n                      ,\n                      <jats:italic>GBA<\/jats:italic>\n                      , and\n                      <jats:italic>ATP13A2<\/jats:italic>\n                      ), while some inherited neuropathies (\n                      <jats:italic>FIG4<\/jats:italic>\n                      ,\n                      <jats:italic>LRSAM1<\/jats:italic>\n                      ,\n                      <jats:italic>SLC25A46<\/jats:italic>\n                      ,\n                      <jats:italic>DNAJB2<\/jats:italic>\n                      , and\n                      <jats:italic>AARS<\/jats:italic>\n                      ) are characterized by overlapping parkinsonian features.
