Outcome Measures

Primary Outcomes (3)

  • Neurophysiological characterization of dopaminergic neurons derived from patients with Parkinson's disease.

    To evaluate the firing frequency in the dopaminergic neurons derived from fibroblasts of patients with Parkinson's disease.

    Baseline

  • Biochemical characterization of dopaminergic neurons derived from patients with Parkinson's disease.

    To determine the amount of dopamine released from differentiated neurons derived from fibroblasts of patients with Parkinson's disease.

    Baseline

  • α-synuclein misfolding in dopaminergic neurons derived from patients with Parkinson's disease.

    To document the presence of abnormal accumulation of misfolded alpha-synuclein in the dopaminergic neurons derived from fibroblasts of patients with Parkinson's disease.
