What this trial studies

This pilot study aims to enhance episodic memory in individuals with mild cognitive impairment (MCI) or dementia through high-definition transcranial direct current stimulation (HD-tDCS) targeting specific brain regions associated with memory and language retrieval. Participants will undergo 10 sessions of either active HD-tDCS or a sham treatment over two weeks, with cognitive assessments conducted at baseline, immediately after treatment, and two months later. The study will also allow participants from the sham group to receive active treatment after the initial phase, enabling a comparison of cognitive outcomes. The goal is to determine the efficacy of this neurostimulation approach in improving cognitive functions.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 55 and older with a diagnosis of mild cognitive impairment or dementia who are fluent in English.

Not a fit: Patients with a history of major neurologic syndromes, substance use disorders, or those with certain medical conditions affecting treatment response may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve memory and cognitive function in patients with mild cognitive impairment and dementia.

How similar studies have performed: Previous studies have suggested that neurostimulation targeting similar brain regions can improve cognitive functions, indicating potential for success in this approach.
