| Abstract | Alzheimer’s disease (AD) is the most prevalent neurodegenerative disorder, affecting tens of millions worldwide with projections indicating increasing prevalence in coming decades. Characterized by progressive cognitive decline, AD manifests with varying degrees of executive, language, and visuospatial impairments that worsen over time, eventually leading to severe psychiatric symptoms, mobility difficulties, sleep disturbances, and incontinence. While pharmacological treatments remain the primary intervention approach, their efficacy often diminishes over time and may produce significant adverse effects. Repetitive transcranial magnetic stimulation (rTMS), as a non-invasive neuromodulation technique, has emerged as a promising alternative or complementary therapy. This literature review examines the therapeutic potential and mechanisms of rTMS in Alzheimer’s disease. Through electromagnetic induction, rTMS can selectively modulate cortical excitability, with high-frequency stimulation (≥ 5 Hz) enhancing neural excitability and low-frequency stimulation (≤ 1 Hz) producing inhibitory effects. Recent clinical evidence demonstrates that rTMS can significantly improve cognitive function, memory, language abilities, and motor performance in AD patients, particularly when administered with optimized parameters targeting key brain regions, such as the dorsolateral prefrontal cortex. The neurobiological mechanisms underlying these effects include enhanced synaptic plasticity, increased expression of neurotrophic factors, modulation of neurotransmitter systems, and reduction of pathological protein aggregation. Meta-analyses indicate that high-frequency protocols (particularly 20 Hz) delivered over at least 3 weeks with a minimum of 20 sessions produce the most significant cognitive improvements, with effects potentially persisting for months post-treatment. Combined approaches integrating rTMS with cognitive training show particular promise through synergistic enhancement of neuroplasticity. Despite encouraging results, standardization of treatment protocols and larger clinical trials are needed to establish definitive guidelines and determine long-term efficacy. This review synthesizes current evidence supporting rTMS as an effective intervention for alleviating clinical symptoms of Alzheimer’s disease while highlighting opportunities for advancing its therapeutic application. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
