Sleep is a fundamental physiological process that plays a critical role in brain health and overall well-being. The impact of sleep on brain function and its potential implications for neurological disorders have garnered significant attention in recent years. This review explores the mechanisms underlying the relationship between sleep and brain health, as well as the implications for neurological disorders. We discuss the importance of sleep in brain homeostasis, synaptic plasticity, memory consolidation, and cognitive function. Furthermore, we delve into the potential consequences of sleep disturbances on neurological disorders, including Alzheimer's disease, Parkinson's disease, and stroke. Understanding the complex interplay between sleep and brain health offers insights into the development of preventive strategies and therapeutic interventions for neurological disorders [1].


Sleep is a dynamic process consisting of different stages and cycles, each serving distinct functions. It is during sleep that the brain undergoes critical restorative processes, such as the clearance of metabolic waste products and the consolidation of memories. Sleep plays a vital role in maintaining brain homeostasis by allowing for the recovery of energy reserves, the regulation of synaptic strength, and the removal of toxic byproducts that accumulate during wakefulness [2]. Synaptic plasticity, the ability of synapses to modify their strength and connections, is essential for learning and memory formation. Sleep has been shown to support the consolidation of newly acquired information, facilitating memory retention and enhancing cognitive performance. During sleep, the brain undergoes reactivation and reorganization of neuronal connections, leading to the integration of new memories into existing networks [3].

Disruptions in sleep patterns, such as sleep deprivation, sleep fragmentation, or sleep disorders, can have detrimental effects on brain health. Sleep disturbances have been associated with an increased risk of developing neurological disorders, including Alzheimer's disease, Parkinson's disease, and stroke. Sleep disturbances may contribute to the accumulation of amyloid-beta plaques in Alzheimer's disease, exacerbate motor symptoms in Parkinson's disease, and affect stroke recovery by impairing neural repair mechanisms and promoting inflammation [4].

The relationship between sleep and neurological disorders is bidirectional. Neurological disorders themselves can disrupt sleep architecture and quality, further exacerbating symptoms and impairing overall brain health. Sleep disturbances, when combined with preexisting neurological conditions, can create a vicious cycle, leading to a negative impact on both sleep quality and disease progression [5].


Sleep is a fundamental process crucial for brain health and optimal cognitive functioning. The intricate relationship between sleep and brain function highlights the importance of sleep in maintaining brain homeostasis, synaptic plasticity, memory consolidation, and overall cognitive performance. Disruptions in sleep patterns and sleep disturbances have been associated with increased vulnerability to neurological disorders, including Alzheimer's disease, Parkinson's disease, and stroke. Addressing sleep-related issues and promoting healthy sleep habits may have implications for the prevention, management, and treatment of these disorders.

Further research is needed to elucidate the underlying mechanisms connecting sleep disturbances and neurological disorders. Developing targeted interventions to improve sleep quality and quantity, as well as exploring the potential therapeutic benefits of enhancing sleep, may offer novel strategies for preventing or mitigating the impact of neurological disorders. Promoting awareness of the critical role of sleep in brain health and incorporating sleep assessments and interventions into clinical practice have the potential to enhance patient outcomes and improve overall brain health. Ultimately, a comprehensive approach that recognizes and addresses the impact of sleep on neurological disorders can contribute to the development of personalized strategies for promoting brain health and improving the quality of life for individuals affected by these conditions.
