BACKGROUND Brain stimulation is a technique that can guide brain plasticity and thus be suitable to treat chronic pain-a disorder that is associated with substantial reorganisation of CNS activity. In fact, the idea of using invasive and non-invasive brain stimulation for pain relief is not new. Studies from the 1950s investigated the use of this therapeutic method for the treatment of chronic ...

The ability of the brain to process information relies on its control of the conduction of electric currents. Brain diseases invariably affect this capability. One of the therapeutic approaches to a variety of neurological disorders therefore includes the application of electric currents and fields to the brain. A successful example of this strategy is the introduction of deep brain stimulation...

Introduction: COVID-19 patients can experience long-term effects including neurological symptoms as part of the long COVID syndrome. The most common associated with this syndrome are cognitive impairments, such brain fog, memory issues or loss concentration, and mood changes, depression anxiety. Non-invasive stimulation, for instance, transcranial direct current stimulation (tDCS), is a treatme...
