The disease is characterized by the occurrence of neurological symptoms over a period of days to weeks, abide by partial or absolute diminutions of various durations. In this review, a concise outline on disease activity and progression of MS, pathogenesis with the special prominence on the biomarkers for the MS as therapeutic targets has been discussed by carrying out a comprehensive literature survey employing chief websites and search engines for investigation...

The most critical issue impeding the development of innovative cerebrospinal medications is the blood-brain barrier (BBB). The BBB limits the ability of most medications to penetrate the brain to the CNS. The BBB structure and functions are summarized, with the physical barrier generated by endothelial tight junctions and the transport barrier formed by transporters within the membrane and vesicular processes. The functions of connected cells, particularly the end feet of astrocytic glial cells, microglia, and pericytes, are described...

BACKGROUND: Audiogenic Epilepsy (AEs) is a subtype of epileptic seizure that is generally caused by high-intensity sounds. A large number of traditional medicines has been explored in this lieu where our study chased Galium verum L. (Rubiaceae), an herbal plant which is commonly known as Lady's Bedstraw, that contains a highly rich chemical composition including flavonoids (Hispidulin, Quercetin, and Kaempferol), and phenolic acids (chlorogenic acid, caftaric acid, and gallic acid). G verum is well known for its antioxidant, neuroprotective, and anti-inflammatory properties...

Brain ischemia occurs following heart failure, thromboembolism, and atherosclerosis, and it is characterized by the disturbance of blood flow resulting from the blockage of blood vessels. After a series of studies, it is deduced that various changes occur following stroke, including neural death and changes in plasticity. Studies have reported that neurotransmitters tend to change following a stroke. These changes that occur surrounding the infarct area following a stroke can be considered new therapeutic targets for stroke rehabilitation...

BACKGROUND: Aging affects cellular functions and impairs tissue homeostasis. Carvacrol, a polyphenolic compound, has been shown to exert a wide range of pharmacological effects, such as antioxidant, anti-inflammatory, and anticancer characteristics. METHODS: This investigation aimed to evaluate the effect of carvacrol in elderly male rats. Carvacrol at a dose of 15 or 30 mg/kg was administrated daily per os for 60 days to aged rats. The liver, heart, and kidney samples were taken for the analysis of oxidative stress markers...

BACKGROUND: Neuropathic pain is a complex chronic condition resulting from the damage or dysfunction of the nervous system. Conventional therapies offer limited success and often come with various adverse effects. Therefore, the exploration of alternative therapies, such as phytoconstituents, may be of substantial interest for their potential to alleviate neuropathic pain. OBJECTIVES: This review systematically examines the diverse roles and mechanisms of various phytoconstituents in modulating neuropathic pain...

INTRODUCTION AND AIM: Seizures due to epilepsy in any form cause a wide range of problems in a patient's physical, psychological, and social health. This study aimed to investigate piperine's anti-seizure and antiepileptic effects and mechanisms. METHODS: In this systematic review study, which was conducted according to the principles of PRISMA 2020, the initial search was conducted on November 2, 2023, using EndNote software. Various databases such as PubMed, Cochrane Library, Web of Science, Embase, and Scopus were searched using specific keywords...

BACKGROUND: The low effectiveness of existing pharmacotherapy strategies for Alzheimer's disease (AD) makes it necessary to develop a new concept for the treatment of this type of dementia. This search is promising to be carried out within the framework of the paradigm of targeting intracellular signaling pathways in Regenerative-Competent Cells (RCCs). OBJECTIVE: The purpose of the research is to study the impact of adenylate cyclase (AC) inhibitor on disorders of the psychoemotional status in aged male C57BL/6 mice, as well as on the dynamics of the content and functioning of RCCs nervous tissue...

Alzheimer's Disease (AD) is a devastating neurological condition characterized by a progressive decline in cognitive function, including memory loss, reasoning difficulties, and disorientation. Its hallmark features include the formation of neurofibrillary tangles and neuritic plaques in the brain, disrupting normal neuronal function. Neurofibrillary tangles, composed of phosphorylated tau protein and neuritic plaques, containing amyloid-β protein (Aβ) aggregates, contribute to the degenerative process...

Drug delivery through the blood-brain barrier (BBB) is one of the key challenges in the modern era of medicine due to the highly semipermeable characteristics of BBB that restrict the entry of various drugs into the central nervous system (CNS) for the management of brain disorders. Drugs can be easily incorporated into carbon nanocarriers that can cross the bloodbrain barrier. Numerous nanocarriers have been developed, including polymeric nanoparticles, carbon nanoparticles, lipid-based nanoparticles, etc...

More than 20 million people worldwide have Alzheimer's disease (AD), making it the most prevalent disease. Patients with AD may live for at least a decade after diagnosis, making it the most common cause of disability in the elderly. Each year, 1% to 4% of the population is affected by AD, with prevalence peaking between ages 65 and 70 and declining to 6% among those over 85. Researchers have accumulated evidence on medicinal herbs that may reverse the pathogenesis of Alzheimer's disease. Alzheimer's disease (AD) is associated with severe memory loss, which can negatively impact social and professional life...

BACKGROUND: A Non-Ergot Dopamine Agonist (NEDA) rotigotine has been designed as a new transdermal drug delivery system. AIM: To maintain optimum homogeneity in drug content, the rotigotine transdermal patch was developed utilizing a solvent casting technique. METHODS: The characteristics of a transdermal patch, including patch weight, folding endurance, patch thickness, surface morphology, tensile strength, swelling rate, surface pH, in vitro release studies, water retention rate, uniformity of drug content, and ex-vivo permeation studies, were determined...

Mild Cognitive Impairment (MCI) is swiftly emerging as a prevalent clinical concern within the elderly demographic. Willoughby spearheaded the pioneering investigation into the evolution of memory decline spanning from the age of 20 to 70. Employing a computerized substitution examination, he pinpointed a zenith in memory prowess at the age of 22, signifying the shift from infancy, succeeded by a gradual decline in later years in 1929. Cognitive impairment impacts various facets, encompassing cognition, memory, perceptual acuity, and linguistic proficiency...

Early detection and intervention are vital for managing AD effectively. OBJECTIVE: This review scrutinizes both in-vivo and in-vitro screening models employed in Alzheimer's disease research. In-vivo models, including transgenic mice expressing AD-related mutations, offer profound insights into disease progression and potential therapeutic targets...

OBJECTIVE: The current study was structured to evaluate the neuroprotective properties of andrographolide in the context of aluminum chloride (AlCl3)-induced neurotoxicity, along with its concurrent impact on spatial memory impairment in Wistar rats. The present investigation elucidated the biochemical and neurobehavioral outcomes of andrographolide treatment in rats, emphasizing the areas of the brain associated with memory, i.e., the cortex and the hippocampus. MATERIALS AND METHODS: Prolonged dosing of AlCl3 (7 mg/kg) intraperitoneally for 10 days exhibited a substantial enhancement in the values of oxidative stress markers associated with a reduction in the concentrations of antioxidant enzymes within the brain...

BACKGROUND: Alzheimer's disease is a neurodegenerative disorder that affects learning, memory and behavioral turbulence in elderly patients. Acetylcholinesterase (AChE) inhibitors act as anti-Alzheimer's agents. Phenothiazine derivatives are considered momentous anti-Alzheimer's agents because of their AChE inhibitory activity. The elevated levels and increased expression of this protein have been associated with Alzheimer's disease. Coumarin-fused phenothiazines have emerged as significant anti-Alzheimer's agents due to their notable receptor inhibitory activity...
