A Review on the Neuroprotective Effect of Berberine against Chemotherapy- induced Cognitive Impairment

Abstract

Abstract: Chemobrain is one of the major side effects of chemotherapy; despite increased research, the mechanisms underlying chemotherapy-induced cognitive changes remain unknown. Several pos-sibly important candidate mechanisms have been identified and will be studied further in the future. Chemobrain is characterized by memory loss, cognitive impairment, difficulty in language, concen-tration, acceleration, and learning. The major characteristic of chemobrain is oxidative stress, mito-chondrial dysfunction, immune dysregulation, hormonal alteration, white matter abnormalities, and DNA damage. Berberine (BBR) is an isoquinoline alkaloid extracted from various berberine species. BBR is a small chemical that easily passes the blood-brain barrier (BBB), making it useful for treat-ing neurodegenerative diseases. Many studies on the pharmacology of BBR have been reported in the past. Furthermore, several clinical and experimental research indicates that BBR has a variety of pharmacological effects. So, in this review, we explore the pathogenesis of chemobrain and the neu-roprotective potential of BBR against chemobrain. We also introduced the therapeutic role of BBR in various neurodegenerative and neurological diseases such as Alzheimer's, Parkinson's disease, mental depression, schizophrenia, anxiety, and also some stroke.
