Testosterone therapy may improve motor symptoms in Parkinson's disease (PD) patients with testosterone deficiency. This case report shows improved tremor and motor control after testosterone administration, correlating with increased hormone levels.

Area of Science:

  • Neuroendocrinology
  • Movement Disorders

Background:

  • Parkinson's disease (PD) involves nigrostriatal pathways, modulated by sex steroids like testosterone.
  • Testosterone deficiency is prevalent in older men and PD patients, impacting non-motor symptoms.

Observation:

  • A case report details a Parkinson's patient with severe testosterone deficiency (1 nmol/L).
  • The patient experienced significant improvements in resting tremor and fine motor control.

Findings:

  • Motor symptom improvements, including handwriting and tremor amplitude, were observed after testosterone administration.
  • Enhanced motor function correlated directly with increased serum testosterone levels.
  • Unified Parkinson's Disease Rating Scale (UPDRS) self-reporting indicated improvement.

Implications:

  • Testosterone replacement therapy may benefit motor symptoms in testosterone-deficient PD patients.
  • This approach could enhance overall well-being in affected individuals.
  • Further research into testosterone's role in PD motor function is warranted.
