tDCS-enhanced motor and cognitive function in neurological diseases

Area of Science:

• Neuroscience
• Neurology
• Medical Technology

Background:

• Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique.
• Initially used for modulating cortical excitability, tDCS is now explored for motor and cognitive functions in healthy individuals and patients.
• This review covers the basic principles and recent applications of tDCS in neurological disorders.

Purpose of the Study:

• To review recent studies on tDCS for enhancing behavioral outcomes and disease-specific symptoms in neurological conditions.
• To provide an overview of tDCS principles and its application in various neurological diseases.
• To discuss the current use and future outlook of tDCS in treating neurological disorders.

Main Methods:

• Literature review of recent studies utilizing tDCS.
• Analysis of tDCS applications in mild cognitive impairment, Alzheimer's disease, movement disorders, epilepsy, and post-stroke deficits.
• Synthesis of findings on tDCS efficacy in improving behavioral outcomes and reducing symptoms.

Main Results:

• tDCS has been investigated for enhancing motor and cognitive functions in various neurological diseases.
• Studies explored tDCS for conditions including mild cognitive impairment, Alzheimer's disease, movement disorders, epilepsy, and stroke.
• Efficacy in improving daily activities and reducing specific symptoms like dystonia or seizures requires further controlled trials.

Conclusions:

• tDCS holds potential as an adjunctive therapy for cognitive or motor training in neurological diseases.
• Controlled randomized trials are necessary to establish the efficacy of tDCS for improving activities and participation.
• The effectiveness of tDCS in reducing disease-specific symptoms such as dystonia or epileptic seizures remains uncertain.
