Trigeminal nerve stimulation (TNS) is a promising strategy in treating diseases of the nervous system. In this study, the effects of TNS on traumatic brain injury (TBI) were investigated in a mouse model. ⋯ This study elucidates the role of TNS as an effective treatment for TBI by inhibiting the occurrence of a secondary brain injury.

This scoping review was undertaken to synthetize and appraise the literature on the potential mechanisms of action of functional electrical stimulation therapy in combination with task-specific training (FEST + TST) in the rehabilitation following stroke, spinal cord injury, traumatic brain injury, or multiple sclerosis. ⋯ The results of this scoping review suggest that FEST + TST can result in multiple effects on different elements of the neuromuscular system, while most research studies were focused on the muscle changes after FEST + TST. Despite the efficacy of the FEST + TST in the neurorehabilitation after CNS injury or disease, the results of this review underline an important knowledge gap with regards to the actual mechanism of action of FEST + TST.

Neurofeedback training is a closed-loop neuromodulatory technique in which real-time feedback of brain activity and connectivity is provided to the participant for the purpose of volitional neural control. Through practice and reinforcement, such learning has been shown to facilitate measurable changes in brain function and behavior. ⋯ The published literature provides mounting high-quality evidence that neurofeedback and BMI control may lead to clinically relevant changes in brain function and behavior.

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, called "penumbra." Adenosine has been shown to play a crucial role in regulating the inflammatory cascade following brain ischemia. Pulsed electromagnetic fields (PEMFs) act as modulators of adenosine receptors, increasing the functionality of the endogenous adenosine. In particular, PEMF exposure induces a significant upregulation of A2A and A3 adenosine receptors in different neuronal cell types. Several lines of evidence suggest that PEMF exposure might play a neuroprotective role after ischemic damage. ⋯ Altogether, these data demonstrate the efficacy of PEMFs against several mechanisms underlying ischemic damage and suggest that PEMFs might represent a novel noninvasive adjunctive treatment for acute ischemic stroke, providing neuroprotection and reducing functional deficits following ischemia.

Neuromodulation for Storage Lower Urinary Tract Symptoms in Parkinson Disease: A Systematic Review.
Bladder symptoms are common in Parkinson disease (PD), affecting quality of life. Medications commonly used such as antimuscarinics can cause frequently intolerable side effects, and therefore, new, better tolerated approaches are needed. Neuromodulation techniques have an established role in urologic disorders; these techniques include tibial nerve stimulation (TNS) and sacral neuromodulation (SNM), which are localized therapies lacking the side effects associated with medication. ⋯ Evidence from case series suggests benefit from TNS in PD, with limited literature on SNM or TMS. Placebo effect from neuromodulation is a concern, and only limited controlled data exist. Future well-designed and sham-controlled studies need to be completed to provide definitive data on the benefit of neuromodulation in PD. Definitively proving the utility of a neuromodulation modality will allow better treatment of bladder symptoms without the need for pharmacologic measures that cause side effects.
