In addition to postural instability, rigidity, tremor, and bradykinesia, patients will experience depression and\/or anxiety at any time during PD. Nortriptyline, as a dual reuptake inhibitor of norepinephrine and serotonin, inhibits alpha\u2010synuclein aggregation and may play an important role in improving the pathological effects of PD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>This study investigated the effects of nortriptyline combined with L\u2010DOPA and benserazide on behavioral, histological, and biochemical changes in a rat model of PD. Methods. Forty\u2010nine rats were randomly assigned to seven groups. Except for the control and sham groups, five other groups underwent stereotactic surgery for the 6\u2010OHDA lesion. We performed a tail suspension swing test and an apomorphine\u2010induced rotation test after 1\u2009week to confirm the PD model. After gradual treatment with three doses (5, 10, and 20\u2009mg\/kg) of nortriptyline combined with L\u2010DOPA and benserazide, the elevated plus\u2010maze test and open field test were performed to determine motor activities, anxiety, and depression. Tissue alterations were evaluated through Nissl staining, tyrosine hydroxylase immunohistochemistry, and Golgi\u2013Cox staining, whereas oxidative stress levels were determined by analyzing malondialdehyde (MDA), superoxide dismutase (SOD), and total antioxidant capacity (TAC) markers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Our results demonstrate that 10\u2009mg\/kg of nortriptyline in combination with L\u2010DOPA and benserazide significantly improved motor activity and reduced the anxiety\u2010 and depression\u2010like behaviors of PD. Histological findings also suggested a protective effect of nortriptyline on dopaminergic neurons in the SNpc. Furthermore, the findings from the antioxidant evaluation and the structure of CA1 hippocampal neurons indicated that a dosage of 10\u2009mg\/kg of nortriptyline might provide the greatest supportive benefit.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Nortriptyline at 10\u2009mg\/kg offers a promising adjunctive therapy for alleviating both motor and nonmotor symptoms of PD.
