Evidence for long‐term survival and function of dopaminergic grafts in progressive Parkinson's disease
Abstract
Two patients with idiopathic Parkinson's disease (Patients 3 and 4 in our series) were followed up to 3 years after grafting of human embryonic dopamine‐rich mesencephalic tissue unilaterally into the putamen. During the first postoperative year both patients showed significant amelioration of parkinsonian symptoms and increased 6‐L‐[18 F]‐fluorodopa uptake in the grafted putamen, as assessed with positron emission tomography. Three years after grafting the patients still exhibited increased fluorodopa uptake in the grafted putamen and significant clinical improvements, evidenced by a reduction of the severity of symptoms and of the time spent in the “off” phase, and by a prolongation of the effect of a single dose of L‐dopa. Between 1 and 3 years after surgery, Patient 3 showed only minor changes of parkinsonian symptoms on the side contralateral to the graft, whereas there was a worsening on the ipsilateral side. Fluorodopa uptake decreased in the nongrafted putamen but was unchanged in the grafted putamen. Patient 4 continued to improve after the first postoperative year and L‐dopa was withdrawn after 32 months. The reduction of parkinsonian symptoms on the side contralateral to the graft became more pronounced between 1 and 3 years after surgery. Fluorodopa uptake further increased in the grafted putamen, whereas no change was detected on the non‐grafted side. These results indicate that grafts of embryonic dopamine neurons can survive, grow, and exert functional effects up to at least 3 years after surgery in the parkinsonian brain, despite an ongoing disease process leading to degeneration of the intrinsic dopamine system.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
