Exploring therapeutical targets and innovative treatments for ischemic stroke: a comprehensive review

Abstract

This review focuses on the current advances in the field of therapeutic targets and treatments for stroke. Stroke is a major health problem worldwide, with significant impacts on morbidity and mortality, and a considerable burden on the medical and socio-economic systems. This review provides a comprehensive overview of the current state of knowledge on acute treatments and therapeutic targets. Current stroke treatments like recanalization therapies focus mainly on restoring blood flow to the brain, reducing cell death, and preventing further damage, but have limitations in terms of efficacy and long-term outcomes. Besides acute treatments (mobile stroke units, telerehabilitation) and acute therapeutic targets, the review focuses on longer-term therapeutic targets, such as neuroprotection and neuroregeneration. Neuroprotective strategies target the mechanisms underlying energy failure, cellular acidosis, mitochondrial dysfunction, endoplasmic reticulum stress, excitotoxicity, calcium channels dysregulation, oxidative stress, neuroinflammation, blood-brain barrier disruption, apoptosis, and ischemia-reperfusion injury. Neuroregenerative approaches include stem cell therapy, gene therapy, growth factors, and rehabilitation techniques that promote the rewiring of neuronal circuits in the brain. Non-pharmacological treatments like neurostimulation and bioengineering are also presented. Additionally, we highlight the challenges and future directions in translating these therapies into clinical practice. Overall, the treatment of ischemic stroke is a complex and multifaceted process that requires a combination of acute measures as well as longer-term strategies to promote brain repair and recovery. The treatment of ischemic stroke has made significant progress in recent years with the development of new treatments and ongoing research to improve outcomes for stroke patients. However, before these therapies can be successfully integrated into routine clinical practise, further research is needed to establish standardised protocols, overcome methodological limitations, and overcome clinical challenges. By further deepening our understanding of the pathophysiology of ischemic stroke and developing innovative treatments, we can improve outcomes and quality of life for stroke survivors.
