Yes, at least significantly improve stuttering. The electrical stimulation devices are: >**Transcranial Direct Current Stimulation (tDCS)**: >Low electrical current to the scalp to modulate neuronal activity - to improve reinforcement learning, or cognitive function >**Transcranial Magnetic Stimulation (TMS)**: >Same, but for treating depression and psychiatric conditions >**Deep Brain Stimulation (DBS)**: >Same, but for treating conditions like Parkinson, tremor, and dystonia >**Electroconvulsive Therapy (ECT)**: >Same, but for treating psychiatric disorders >**Functional Electrical Stimulation (FES)**: >Same, but for stimulating specific muscles or nerves to restore or improve motor function, mostly used in rehabilitation for spinal cord injuries >**Cranial Electrotherapy Stimulation (CES)**: >Same, but for treating anxiety and insomnia >**Vagus Nerve Stimulation (VNS)**: >Same, but for treating epilepsy But, I've only read in research - about stuttering and Transcranial Direct Current Stimulation (tDCS). Research found abnormal neural brain activation during stuttering. And, this device (tDCS) has proven to reduce stuttering, when applied over the supplementary motor area (SMA). Here are some research studies that investigated it: ([1](https://www.brainstimjrnl.com/article/S1935-861X(23)00334-0/fulltext)) [Research](https://www.brainstimjrnl.com/article/S1935-861X(23)00334-0/fulltext): The Effect of Transcranial Direct Current Stimulation on Stuttering: A Preliminary Report (2023) [(2) Research](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5240850/): Investigating the feasibility of using transcranial direct current stimulation to enhance fluency in people who stutter (2017) [(3) Research](https://pubmed.ncbi.nlm.nih.gov/31824276/): Stuttering Severity Modulates Effects of Non-invasive Brain Stimulation in Adults Who Stutter (2019) It does seem to have become more effective over the years; now in 2024 it seems more effective than previous years. So, yes maybe one day this device can help bring us at least closer to early onset stuttering
