Anteromedial GPi deep brain stimulation in Tourette syndrome: The first case series from Iran.

Objectives: Tourette syndrome (TS) is a neuropsychiatric disorder characterized by childhood onset motor and phonic tics. In refractory cases, deep brain stimulation (DBS) with different targets including anteromedial Globus pallidus (AM-GPi) looks promising.

Patients And Methods: Patients with TS diagnosed according to DSM-IV TR criteria with severe medication-recalcitrant disease referred to our DBS clinic, were recruited for this study.

The effect of bilateral subthalamic nucleus deep brain stimulation (STN-DBS) on the acoustic and prosodic features in patients with Parkinson's disease: A study protocol for the first trial on Iranian patients.

The effect of subthalamic nucleus deep brain stimulation (STN-DBS) on the voice features in Parkinson's disease (PD) is controversial. No study has evaluated the voice features of PD underwent STN-DBS by the acoustic, perceptual, and patientbased assessments comprehensively. Furthermore, there is no study to investigate prosodic features before and after DBS in PD.
