We report the neuropathological findings in a patient with Parkinson's disease (PD) associated with Basque R1441G-LRRK2/dardarin mutation. The patient was a man with disease onset at 68 years of age, with unilateral rest tremor; the Parkinsonism was well controlled with medication for 15 years. He died at the age of 86, after 18 years of evolution.
