Transcranial Direct Current Stimulation For Neurodegeneration is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
| Property | Value |
|---|---|
| Category | Neuromodulation |
| Target Conditions | Alzheimer's Disease, Parkinson's Disease, Stroke, Depression |

| Evidence Level | Promising preclinical, early clinical |
Transcranial Direct Current Stimulation (tDCS) is a non-invasive brain stimulation technique that uses low-intensity direct electrical currents to modulate neuronal activity. By applying weak electrical currents (typically 1-2 mA) through electrodes placed on the scalp, tDCS can alter cortical excitability and modulate neural network activity. Unlike transcranial magnetic stimulation (TMS), which induces action potentials, tDCS works by subthreshold polarization of neuronal membranes, making it a gentle but potentially effective neuromodulation approach.
The technique has gained significant research interest for neurodegenerative diseases due to its safety profile, relatively low cost, and potential to enhance cognitive and motor function. Studies have explored tDCS as an adjunct therapy for Alzheimer's disease (AD), Parkinson's disease (PD), stroke rehabilitation, and depression associated with neurodegeneration. While still considered investigational, tDCS represents a promising avenue for non-pharmacological intervention in these conditions.
