The Effectiveness of Transcranial Electrical Stimulation on the Pattern Brain Waves and Blood Pressure in Patients with Generalized Anxiety Disorder

BACKGROUND Percutaneous transcatheter closure of patent foramen ovale has been proposed to prevent recurrent strokes in young adults. Contrast transcranial Doppler ultrasonography provides a functional, semiquantitative evaluation of right-to-left cardiac shunt. AIMS To evaluate the efficacy of percutaneous closure of patent foramen ovale in suppressing right-to-left shunt (assessed using tra...

This study presents and tests the clinical validity of a hemodynamic grading system that depends on noninvasive transcranial Doppler ultrasonographic parameters. The suggested transcranial Doppler-based grading system was compared with the Spetzler-Martin anatomic grading for prognosticative validity and clinical dependability. We concluded the following: (1) The pulsatility index was shown to ...

OBJECTIVE Accurate and reproducible coil positioning is important for headache research using transcranial magnetic stimulation protocols. We aimed to design a transcranial magnetic stimulation coil holder and demonstrate reliability of test-retest coil positioning. METHODS A coil holder was developed and manufactured according to three principles of stability, durability, and three-dimension...

Transcranial sonography is a highly sensitive noninvasive sonographic method for detection of early and specific echogenic changes in basal ganglia of patients with some neurodegenerative diseases. Transcranial sonography showed substantia nigra hyperechogenicity as a typical echo feature in idiopathic Parkinson disease and lenticular nucleus hyperechogenicity as a characteristic finding in aty...

BACKGROUND Several recent studies suggest that repetitive transcranial magnetic stimulation can temporarily reduce pain perception in neuropathic pain patients and in healthy adults using laboratory pain models. No studies have investigated the effects of prefrontal cortex stimulation using transcranial magnetic stimulation on postoperative pain. METHODS Twenty gastric bypass surgery patients...
