Abstract Background Neuropsychiatric disorders significantly burden individuals and society, necessitating the exploration of innovative treatment approaches. Non-invasive brain stimulation techniques have emerged as promising interventions for these disorders, offering potential therapeutic benefits with minimal side effects. This narrative review provides a comprehensive overview of non-invasive brain stimulation techniques' current applications and future directions in managing neuropsychiatric disorders. Methods A thorough search of relevant literature was conducted to identify studies investigating non-invasive brain stimulation techniques in neuropsychiatric disorders. The selected studies were critically reviewed, and their findings were synthesised to provide a comprehensive overview of the current state of knowledge in the field. Results The review highlights the current applications of non-invasive brain stimulation techniques in neuropsychiatric disorders, including major depressive disorder, Parkinson's disease, schizophrenia, insomnia, and cognitive impairments. It presents evidence supporting the efficacy of these techniques in modulating brain activity, alleviating symptoms, and enhancing cognitive functions. Furthermore, the review addresses challenges such as interindividual variability, optimal target site selection, and standardisation of protocols. It also discusses potential future directions, including exploring novel target sites, personalised stimulation protocols, integrating with other treatment modalities, and identifying biomarkers for treatment response. Conclusion Non-invasive brain stimulation techniques offer promising avenues for managing neuropsychiatric disorders. Further research is necessary to optimise stimulation protocols, establish standardised guidelines, and identify biomarkers for treatment response. The findings underscore the potential of non-invasive brain stimulation techniques as valuable additions to the armamentarium of neuropsychiatric treatments.

Abstract Background Surgical management is one of the mainstay management options for cerebrovascular diseases, which is not only curative but also preventive. However, there's a gap between the surgical management of cerebrovascular disease in Africa when compared to the developed parts of the world. Methods A literature search was done on the state of Cerebrovascular surgery in Africa from databases such as Pubmed, Embase, and Google Scholar, articles we fetched and meticulously reviewed. Results We found gaps in the surgical management of cerebrovascular diseases such as stroke in African countries when compared to developed countries. The challenges facing the surgical management of cerebrovascular disease in Africa include a low number of neurosurgeons and vascular surgeons trained in the surgical management of these diseases, a lack of adequate facilities for surgical management, and others. The burden of cerebrovascular diseases in Africa is great, and this warrants an improvement in the surgical management of the conditions, which includes primary prevention of such diseases through public health education on risk factors, improvement of health facilities to accommodate recent advances in the cerebrovascular surgeries, establishments of several neurosurgery training centers. Conclusion The practice of surgical management of cerebrovascular disease in Africa needs to be optimized for it to be at the global standard and for better outcomes and management of patients.
