Magnetic Resonance Acoustic Radiation Force Imaging (MR‐ARFI)

Journal of Magnetic Resonance Imaging, EarlyView.
This review covers the theoretical background, pulse sequence considerations, practical implementations, and multitudes of applications of magnetic resonance acoustic radiation force imaging (MR‐ARFI) described to date. MR‐ARFI is an approach to encode tissue displacement caused by the acoustic radiation force of a focused ultrasound field into the ...

Speech Differences between Multiple System Atrophy and Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Delineation of Parkinson's disease (PD) from multiple system atrophy (MSA) can be challenging in early disease stages. Speech characteristics have been studied as digital biomarkers in PD and ataxias. Currently, data on speech in MSA is limited.

Myoclonic Dystonia: A Common Phenomenology in the Pleomorphic Movements of Angelman Syndrome

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Angelman syndrome (AS) is a neurodevelopmental disorder characterized by developmental delay, intellectual disability, a sociable demeanor, and abnormal movements. People with AS often exhibit multiple types of abnormal movements, including nonepileptic myoclonus, tremor, and dystonia, which hamper attempts to identify phenomenology

Transcranial direct current stimulation in psychiatric disorders

World Journal of Psychiatry, 2015
The interest in non-invasive brain stimulation techniques is increasing in recent years. Among these techniques, transcranial direct current stimulation (tDCS) has been the subject of great interest among researchers because of its easiness to use, low cost, benign profile of side effects and encouraging results of research in the field.

Analgesic Effects of Repetitive Transcranial Magnetic Stimulation at Different Stimulus Parameters for Neuropathic Pain: A Randomized Study

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives The aim of the present study was to investigate the analgesic effects of repetitive transcranial magnetic stimulation over the primary motor cortex (M1‐rTMS) using different stimulation parameters to explore the optimal stimulus condition for treating neuropathic pain.

Transcranial Temporal Interference Stimulation of the Right Globus Pallidus in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Invasive deep brain stimulation (DBS) has been shown to be effective in treating patients with Parkinson's disease (PD), yet its clinical use is limited to patients at the advanced stage of the disease. Transcranial temporal interference stimulation (tTIS) may be a novel nonneurosurgical and safer alternative, yet its therapeutic ...

Pulsed Electromagnetic Fields: A Novel Attractive Therapeutic Opportunity for Neuroprotection After Acute Cerebral Ischemia

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Acute cerebral ischemia is characterized by several pathological processes evolving during time, which contribute to the final tissue damage. Secondary processes, such as prolonged inflammatory response, impaired mitochondrial function and oxidative stress, are responsible for the progression of brain injury to the peri‐infarct area,

Noninvasive Temporal Interference Stimulation of the Subthalamic Nucleus in Parkinson's Disease Reduces Beta Activity

Movement Disorders, EarlyView.
Abstract Background Temporal interference stimulation (TIS) is a novel noninvasive electrical stimulation technique to focally modulate deep brain regions; a minimum of two high‐frequency signals (f1 and f2 > 1 kHz) interfere to create an envelope‐modulated signal at a deep brain target with the frequency of modulation equal to the difference frequency:

A Randomized, Sham‐Controlled Trial of Repetitive Transcranial Magnetic Stimulation Targeting M1 and S2 in Central Poststroke Pain: A Pilot Trial

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Central poststroke pain (CPSP), a neuropathic pain condition, is difficult to treat. Repetitive transcranial magnetic stimulation (rTMS) targeted to the primary motor cortex (M1) can alleviate the condition, but not all patients respond. We aimed to assess a promising alternative rTMS target, the secondary somatosensory cortex (S2),

Motor Cortex Disinhibition Correlates with Olfactory Dysfunction in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Motor cortex disinhibition, as measured by impaired short‐interval intracortical inhibition (SICI) using transcranial magnetic stimulation (TMS), is a well‐established feature of Parkinson's disease (PD). However, its substantial variability among patients remains unexplained, prompting questions about its origin, clinical relevance,
