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,

Spinal and cortical spreading depression enhance spinal cord activity

Neurobiology of Disease, 2004
Cortical spreading depression (CSD) has been suggested to underlie some neurological disorders such as migraine. Despite the intensity with which many investigators have studied SD in the brain, only a few studies have aimed to identify SD in the spinal ...

Progress of non‐motor symptoms in early‐onset Parkinson's disease

Ibrain, EarlyView.
This study reviews the research progress related to non‐motor symptoms (NMS) in patients with early onset Parkinson's disease (EOPD), including neuropsychiatric symptoms, autonomic dysfunction, sleep disorders, and sensory disorders and also summarizes the characteristics of NMS in the genetic form of Parkinson's disease (PD).

Heart Rate Variability Features as Predictors of Intermittent Theta‐Burst Stimulation Response in Posttraumatic Stress Disorder

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Background Posttraumatic stress disorder (PTSD) is associated with autonomic dysfunction as indicated by deficits in the sympathetic and parasympathetic nervous systems. These abnormalities are expressed as elevated heart rate and reduced heart rate variability (HRV), respectively.

Aura and osmophobia are associated with the IL1A -889C > T (rs1800587) variant in migraine

Arquivos de Neuro-Psiquiatria
Background Migraine belongs to the group of primary headaches, affecting 14.4% of the global population. The pathophysiological mechanisms of migraine involve the interplay between hypothalamic activation, cortical spreading depression ...

Bistable dynamics underlying excitability of ion homeostasis in neuron models

, 2014
When neurons fire action potentials, dissipation of free energy is usually not directly considered, because the change in free energy is often negligible compared to the immense reservoir stored in neural transmembrane ion gradients and the long-term ...

Aquaporin-4-dependent K(+) and water transport modeled in brain extracellular space following neuroexcitation. [PDF]

, 2013
Potassium (K(+)) ions released into brain extracellular space (ECS) during neuroexcitation are efficiently taken up by astrocytes. Deletion of astrocyte water channel aquaporin-4 (AQP4) in mice alters neuroexcitation by reducing ECS [K(+)] accumulation ...

Losing brain networks during death

Interdisciplinary Medicine, EarlyView.
Abstract Death represents the end of all living organisms. The pattern of brain activity disappearance following death, however, has not been fully elucidated. Here we investigated brain activity dynamics following cardiac arrest using ultra‐high field 11.7 T magnetic resonance imaging (MRI) in longitudinal approach and multi‐modal analyses. Initially,

ESPGHAN/NASPGHAN guidelines for treatment of irritable bowel syndrome and functional abdominal pain‐not otherwise specified in children aged 4–18 years

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives Abdominal pain related disorders of gut–brain interaction (AP‐DGBIs) such as irritable bowel syndrome (IBS) and functional abdominal pain‐not otherwise specified (FAP) are common conditions in children, significantly impacting quality of life.

Recording, analysis, and interpretation of spreading depolarizations in neurointensive care: Review and recommendations of the COSBID research group. [PDF]

, 2016
Spreading depolarizations (SD) are waves of abrupt, near-complete breakdown of neuronal transmembrane ion gradients, are the largest possible pathophysiologic disruption of viable cerebral gray matter, and are a crucial mechanism of lesion development ...
