Effect of Neurotropic and Immunotropic Drugs on Leukocyte Elastase Activity In Vitro.

Leukocyte elastase is a marker of inflammation. Previously, a relationship was found between the severity of mental disorders in patients and elastase-like activity of blood plasma. The effect of various neurotropic drugs on leukocyte elastase activity was analyzed in an in vitro experiment. We revealed an inhibitory effect of the benzodiazepine tranquilizers diazepam and bromodihydrochlorophenylbenzodiazepine and immunomodulators aminodihydrophthalazinedione and diclofenac on the plasma elastase-like activity of healthy donors and pure human neutrophil elastase. The antipsychotics chlorpromazine and alimemazine, as well as the nootropic vinpocetine increased elastase-like activity in a dose-dependent manner. The activating effect of chlorpromazine and vinpocetine, but not alimemazine, was reproduced in neutrophil elastase. We hypothesized that these drugs can affect the development of inflammatory reactions in the complex therapy of mental disorders.

Trends of use and characterisation of anti-dementia drugs users: a large multinational-network population-based study.

BACKGROUND: An updated time-trend analysis of anti-dementia drugs (ADDs) is lacking. The aim of this study is to assess the incident rate (IR) of ADD in individuals with dementia using real-world data. SETTING: Primary care data (country/database) from the UK/CPRD-GOLD (2007-20), Spain/SIDIAP (2010-20) and the Netherlands/IPCI (2008-20), standardised to a common data model. METHODS: Cohort study. Participants: dementia patients ≥40 years old with ≥1 year of previous data. Follow-up: until the end of the study period, transfer out of the catchment area, death or incident prescription of rivastigmine, galantamine, donepezil or memantine. Other variables: age/sex, type of dementia, comorbidities. Statistics: overall and yearly age/sex IR, with 95% confidence interval, per 100,000 person-years (IR per 105 PY (95%CI)). RESULTS: We identified a total of (incident anti-dementia users/dementia patients) 41,024/110,642 in UK/CPRD-GOLD, 51,667/134,927 in Spain/SIDIAP and 2,088/17,559 in the Netherlands/IPCI.In the UK, IR (per 105 PY (95%CI)) of ADD decreased from 2007 (30,829 (28,891-32,862)) to 2010 (17,793 (17,083-18,524)), then increased up to 2019 (31,601 (30,483 to 32,749)) and decrease in 2020 (24,067 (23,021-25,148)). In Spain, IR (per 105 PY (95%CI)) of ADD decreased by 72% from 2010 (51,003 (49,199-52,855)) to 2020 (14,571 (14,109-15,043)). In the Netherlands, IR (per 105 PY (95%CI)) of ADD decreased by 77% from 2009 (21,151 (14,967-29,031)) to 2020 (4763 (4176-5409)). Subjects aged ≥65-79 years and men (in the UK and the Netherlands) initiated more frequently an ADD. CONCLUSIONS: Treatment of dementia remains highly heterogeneous. Further consensus in the pharmacological management of patients living with dementia is urgently needed.

A comprehensive assessment of the cholinergic-supporting and cognitive-enhancing effects of Rosa damascena Mill. (Damask rose) essential oil on scopolamine-induced amnestic rats.

INTRODUCTION: Alzheimer's disease (AD) is a neurodegenerative condition characterized by gradual loss of cognitive abilities (dementia) and is a major public health problem. Here, we aimed at investigating the effects of Rosa damascena essential oil (RDEO) on learning and memory functions in a rat model of amnesia induced by scopolamine, as well as on changes in acetylcholinesterase (AChE) activity, M1 muscarinic acetylcholine receptor (mAChR) expression, and brain-derived neurotrophic factor (BDNF) levels in the extracted brain tissues. METHODS: The control, amnesia (scopolamine, 1 mg/kg/i.p.) and treatment (RDEO, 100 µL/kg/p.o. or galantamine, 1.5 mg/kg/i.p.) groups were subjected to Morris water maze and new object recognition tests. AChE activity was assayed by ELISA, and M1 mAChR and BDNF concentration changes were determined by western blotting. Also, using computational tools, human M1 mAChR was modeled in an active conformation, and the major components of RDEO were docked onto this receptor. RESULTS: According to our behavioral tests, RDEO was able to mitigate the learning and memory impairments caused by scopolamine in vivo. Our in vitro assays showed that the observed positive effects correlated well with a decrease in AChE activity and an increase in M1 mAChR and BDNF levels in amnestic rat brains. We also demonstrated in an in silico setting that the major components of RDEO, specifically -citronellol, geraniol, and nerol, could be accommodated favorably within the allosteric binding pocket of active-state human M1 mAChR and anchored here chiefly by hydrogen-bonding and alkyl-π interactions. CONCLUSION: Our findings offer a solid experimental foundation for future RDEO-based medicinal product development for patients suffering from AD.

Integration of a facile sustainable resonance Rayleigh scattering switchable-based system for feasible determination of centrophenoxine, a nootropic and antioxidant agent; application to crude materials and dosage forms.

The proposed research adheres to a certain methodology to ensure that the technique used for analyzing the centrophenoxine drug is sustainable and green. It is important to highlight that several tools that have been recently developed were utilized as potential indicators of environmental sustainability and applicability. The present research presents a novel and entirely innovative method utilizing ultrasensitive spectrofluorimetry for the detection of centrophenoxine (CPX) drug. The employed methodology in this study involved the utilization of one-step, one-pot, and direct spectrofluorimetric technique, which was found to be both efficient and environmentally sustainable in the validation and assessment of the drug. Simply, when CPX and erythrosine B reagent were combined in an acidic environment, the highly resonance Rayleigh scattering product was immediately produced. The sensitivity limits were observed to be within the range of 15-47 ng mL-1, whereas the linearity was assessed to be in the range of 50-2000 ng mL-1. The optimal settings for all modifiable parameters of the system were ascertained through an analysis of centrophenoxine-erythrosine B complexes. Moreover, the system demonstrated compliance with International Council for Harmonization (ICH) specifications without encountering any issues. The suggested process was then rated on different recent environmental safety measuring metrics to see how good it was for the environment. Fortunately, the WAC standards that combine ecological and functional elements utilizing the Green/Red/Blue (RGB 12) design also acclaimed the current analytical technique as a white one. Additionally, a new applicability evaluation tool (BAGI) was employed to estimate the practicability of the planned method in the analytical chemistry field.

Donepezil for dementia with Lewy bodies: meta-analysis of multicentre, randomised, double-blind, placebo-controlled phase II, III, and, IV studies.

BACKGROUND: Current evidence for the management of symptoms associated with dementia with Lewy bodies (DLB) using donepezil is limited. We conducted a meta-analysis of three randomised controlled trials of donepezil in patients with DLB to investigate the overall efficacy of donepezil on Mini-Mental State Examination (MMSE), Neuropsychiatric Inventory (NPI), and Clinician's Interview-Based Impression of Change-plus Caregiver Input (CIBIC-plus). METHODS: A meta-analysis was performed using the data of 312 patients administered placebo or 10 mg donepezil. Overall mean score differences for MMSE, NPI-2, and NPI-10 from baseline to week 12 and their 95% confidence intervals (CI) were estimated. For CIBIC-plus, which was transformed from a seven-point grade to a dichotomous outcome (improvements/no improvements), odds ratio (OR) and its 95% CI were estimated. Random-effects models were used, and heterogeneity was evaluated using the Cochrane's Q test and I2 statistic. RESULTS: Heterogeneity was suspected for NPI-2 (P < 0.05; I2 = 87.2%) and NPI-10 (P < 0.05; I2 = 67.7%) while it was not suspected for MMSE (P = 0.23; I2 = 32.4%) and CIBIC-plus (P = 0.26; I2 = 19.8%). The overall mean MMSE score difference (mean difference: 1.50; 95% CI, 0.67-2.34) and the overall odds of improving CIBIC-plus (OR: 2.20; 95% CI, 1.13-4.26) from baseline to week 12 were higher in the donepezil group than in the placebo group. CONCLUSION: Results of our meta-analysis indicated overall efficacy of donepezil on cognitive impairment and global clinical status in patients with DLB.

Efficacy and safety of donepezil in patients with dementia with Lewy bodies: results from a 12-week multicentre, randomised, double-blind, and placebo-controlled phase IV study.

BACKGROUND: Donepezil has been approved in Japan for the treatment of dementia with Lewy bodies (DLB) based on clinical trials showing its beneficial effects on cognitive impairment. This phase IV study evaluated the efficacy of donepezil by focusing on global clinical status during a 12-week double-blind phase. METHODS: Patients with probable DLB were randomly assigned to the placebo (n = 79) or 10 mg donepezil (n = 81) groups. The primary endpoint was changes in global clinical status, assessed using the Clinician's Interview-Based Impression of Change plus Caregiver Input (CIBIC-plus). We also assessed four CIBIC-plus domains (general condition, cognitive function, behaviour, and activities of daily living) and changes in cognitive impairment and behavioural and neuropsychiatric symptoms measured using the Mini-Mental State Examination (MMSE) and the Neuropsychiatric Inventory (NPI), respectively. RESULTS: Although donepezil's superiority was not shown in the global clinical status, a significant favourable effect was detected in the cognitive domain (P = 0.006). MMSE scores improved in the donepezil group after adjustments in post hoc analysis (MMSE mean difference, 1.4 (95% confidence interval (CI), 0.42-2.30), P = 0.004). Improvements in NPIs were similar between the groups (NPI-2: -0.2 (95% CI, -1.48 to 1.01), P = 0.710; NPI-10: 0.1 (95% CI, -3.28 to 3.55), P = 0.937). CONCLUSION: The results support the observation that the efficacy of 10 mg donepezil in improving cognitive function is clinically meaningful in DLB patients. The evaluation of global clinical status might be affected by mild to moderate DLB patients enrolled in this study. No new safety concerns were detected.

Update on Cognitive Enhancers Among the Older Adult Population: A Clinical Review.

PURPOSE OF REVIEW: The purpose of this review is to identify key classes of medications that are used for the treatment of older adults with neurocognitive disorders. RECENT FINDINGS: Clinical factors play a critical role in the prescribing of these medication classes for the treatment of dementia. The variation in prescribing trends is determined by the presence of medical and psychiatric comorbidities commonly occurring in older adults and is based on the consideration of potential interactions between pharmacotherapies for the comorbidities and for the dementia. Six medication classes currently exist to address the neurocognitive aspect of dementia, with varying pharmacokinetic and pharmacodynamic profiles. We review these six classes in this report and provide a provision of clinical insights regarding the use of these agents. While literature exists on the safety and efficacy of individual medication options for the treatment of dementia in the older adult population, further research is needed to provide clearer guidance regarding the specific use of these agents in clinical practice.

Prevalence of the use of prescription stimulants as "study drugs" by UK university students: A brief report.

INTRODUCTION: There is media concern over students using prescription stimulants as "cognitive enhancers" to try and improve their academic performance. However, there is limited evidence about the prevalence of this behaviour in the United Kingdom, or whether it has increased in recent years. METHODS: We review survey studies on students' use of cognitive enhancers. RESULTS: Overall reported use is low, with some inconclusive evidence that it is increasing. Use of modafinil appears to be higher than that of methylphenidate or dexamphetamine. CONCLUSION: There is a clear need for large-scale research in this area, using representative sampling and survey methods that protect student anonymity.

Potentiation of prefrontal cortex dopamine function by the novel cognitive enhancer d-govadine.

Cognitive impairment is a debilitating feature of psychiatric disorders including schizophrenia, mood disorders and substance use disorders for which there is a substantial lack of effective therapies. d-Govadine (d-GOV) is a tetrahydroprotoberberine recently shown to significantly enhance working memory and behavioural flexibility in several prefrontal cortex (PFC)-dependent rodent tasks. d-GOV potentiates dopamine (DA) efflux in the mPFC and not the nucleus accumbens, a unique pharmacology that sets it apart from many dopaminergic drugs and likely contributes to its effects on cognitive function. However, specific mechanisms involved in the preferential effects of d-GOV on mPFC DA function remain to be determined. The present study employs brain dialysis in male rats to deliver d-GOV into the mPFC or ventral tegmental area (VTA), while simultaneously sampling DA and norepinephrine (NE) efflux in the mPFC. Intra-PFC delivery or systemic administration of d-GOV preferentially potentiated medial prefrontal DA vs NE efflux. This differential effect of d-GOV on the primary catecholamines known to affect mPFC function further underscores its specificity for the mPFC DA system. Importantly, the potentiating effect of d-GOV on mPFC DA was disrupted when glutamatergic transmission was blocked in either the mPFC or the VTA. We hypothesize that d-GOV acts in the mPFC to engage the mesocortical feedback loop through which prefrontal glutamatergic projections activate a population of VTA DA neurons that specifically project back to the PFC. The activation of a PFC-VTA feedback loop to elevate PFC DA efflux without affecting mesolimbic DA release represents a novel approach to developing pro-cognitive drugs.

From functional neuroimaging to neurostimulation: fNIRS devices as cognitive enhancers.

Functional near-infrared spectroscopy (fNIRS) relies on near-infrared (NIR) light for changes in tissue oxygenation. For decades, this technique has been used in neuroscience to measure cortical activity. However, recent research suggests that NIR light directed to neural populations can modulate their activity through "photobiomodulation" (PBM). Yet, fNIRS is being used exclusively as a measurement tool. By adopting cognitive tests sensitive to prefrontal functioning, we show that a 'classical' fNIRS device, placed in correspondence of the prefrontal cortices of healthy participants, induces faster RTs and better accuracy in some of the indexes considered. A well-matched control group, wearing the same but inactive device, did not show any improvement. Hence, our findings indicate that the 'standard' use of fNIRS devices generates PBM impacting cognition. The neuromodulatory power intrinsic in that technique has been so far completely overlooked, and future studies will need to take this into account.

Exploring the understanding, source of availability and level of access of cognitive enhancers among university students in the United Arab Emirates: A qualitative study.

OBJECTIVE: The use of prescription stimulants for cognitive enhancement by healthy university students, identified as the largest cohort of cognitive enhancer (CE) users, is of growing interest. The purpose of this study was to look at the understanding, perception, experience, and level of access of CEs among healthy university students in the United Arab Emirates (UAE). METHODS: The study was conducted in six highly competitive university programmes. Semi-structured interviews were conducted with 18 university students to discuss their own experiences and those of their friends and peers regarding the use of prescription stimulants. In addition, semi-structured interviews were conducted with seven teaching faculty staff members (registered pharmacists and medical doctors) to explore their views on the use of CEs in their university. RESULTS: Data were analysed thematically for the identification of themes and subthemes within the data using coding. It was found that, 'Adderall' was the most common prescribed CE drug and caffeine super strength pills were the most common non-prescribed CE drug, both reported to enhance concentration, motivation, and meet academic deadlines. CONCLUSIONS: It is expected that the findings of this study will be of interest to a wide range of services in UAE universities. This will enable them to raise awareness about the use of CEs among students.

Safety, tolerability, and pharmacokinetics of oral (S)-oxiracetam in Chinese healthy volunteers: A randomized, double-blind, controlled phase I study.

BACKGROUND AND OBJECTIVE: (S)-oxiracetam is the major active enantiomer of oxiracetam, which is being developed for dementia. This trial was designed to evaluate the safety, tolerability, and pharmacokinetics of oral (S)-oxiracetam in healthy Chinese volunteers. METHODS: A randomized, controlled, double-blind and dose-escalation design was used in this Phase I trial, which consisted of a single-ascending-dose (SAD) study (400-2000 mg) and a multiple-ascending-dose (MAD) study (400-1600 mg). Blood, urine and feces samples were collected for pharmacokinetic analysis. Safety was evaluated by monitoring adverse events (AEs). RESULTS: AEs in both studies were mild or moderate in severity and dose-independent. In the SAD study, no chiral transformation was observed. 55.03% and 36.16% of (S)-oxiracetam was excreted unchanged in urine and feces, respectively. Exposures exhibited dose-proportional increases over the range of 400 to 1600 mg but almost unchanged from 1600 to 2000 mg. (S)-oxiracetam was absorbed rapidly, reaching a peak at 0.75-1.00 h, and t1/2 was 6.12-6.60 h. Food had no effect on AUC, but prolonged Tmax to 3.00 h. In the MAD study, steady-state was observed on day 5. Mild accumulations were observed after 7 days of repeated dosing. CONCLUSION: (S)-oxiracetam was safe and tolerated with favorable pharmacokinetic profiles at all study doses, providing dosing evidence for further efficacy evaluation.

Cognitive-Enhancing Effects of Acetylcholine Receptor Agonists in Group-Housed Cynomolgus Monkeys Who Drink Ethanol.

The cognitive impairments that are often observed in patients with alcohol use disorder (AUD) partially contribute to the extremely low rates of treatment initiation and adherence. Brain acetylcholine receptors (AChR) mediate and modulate cognitive and reward-related behavior, and their distribution can be altered by long-term heavy drinking. Therefore, AChRs are promising pharmacotherapeutic targets for treating the cognitive symptoms of AUD. In the present study, the procognitive efficacy of two AChR agonists, xanomeline and varenicline, were evaluated in group-housed monkeys who self-administered ethanol for more than 1 year. The muscarinic AChR antagonist scopolamine was used to disrupt performance of a serial stimulus discrimination and reversal (SDR) task designed to probe cognitive flexibility, defined as the ability to modify a previously learned behavior in response to a change in reinforcement contingencies. The ability of xanomeline and varenicline to remediate the disruptive effects of scopolamine was compared between socially dominant and subordinate monkeys, with lighter and heavier drinking histories, respectively. We hypothesized that subordinate monkeys would be more sensitive to all three drugs. Scopolamine dose-dependently impaired performance on the serial SDR task in all monkeys at doses lower than those that produced nonspecific impairments (e.g., sedation); its potency did not differ between dominant and subordinate monkeys. However, both AChR agonists were effective in remediating the scopolamine-induced deficit in subordinate monkeys but not in dominant monkeys. These findings suggest xanomeline and varenicline may be effective for enhancing cognitive flexibility in individuals with a history of heavy drinking. SIGNIFICANCE STATEMENT: Procognitive effects of two acetylcholine (ACh) receptor agonists were assessed in group-housed monkeys who had several years' experience drinking ethanol. The muscarinic ACh receptor agonist xanomeline and the nicotinic ACh receptor agonist varenicline reversed a cognitive deficit induced by the muscarinic ACh receptor antagonist scopolamine. However, this effect was observed only in lower-ranking (subordinate) monkeys and not higher-ranking (dominant monkeys). Results suggest that ACh agonists may effectively remediate alcohol-induced cognitive deficits in a subpopulation of those with alcohol use disorder.

[Bacosides: a study of neurobiological activity, prospects for application]. / Bakozidy: izuchenie neirobiologicheskoi aktivnosti i perspektivy primeneniya.

Bacosides are the main biologically active components derived from the plant bacopa monnieri (Bacopa monnieri (L.) Wettst.), which has been used as a nootropic in Indian medicine for many centuries. In recent years, these compounds have attracted attention because of their wide range of neurobiological effects. The neuroprotective effects of bacosides on brain neurons under the influence of various damaging factors (neurotoxins, oxidative stress, beta-amyloid deposition, cigarette smoke, etc.) have been established. It was shown that these substances reduce the levels of inflammatory cytokines and inhibit the processes of demyelination of neurons. The anticonvulsant effect of bacosides has been established. These compounds also improve cognitive functions, including memory and learning abilities. The effects associated with the influence on the dopaminergic and serotonergic systems of the striatum are of interest for the therapy of morphine addiction. The theoretical justifications for the future use of bacosides as a multipurpose means of complex therapy of individual diseases in neurological and psychiatric practice are presented.

[Recognan (citicoline) efficacy and safety in cognitive impairment correction of various nosological forms]. / Effektivnost' i bezopasnost' Rekognana (tsitikolin) pri korrektsii kognitivnykh narushenii razlichnoi etiologii.

Insufficiency of a choline derivative (acetylcholine) can lead to the development of cognitive impairment (CI). One of the most well-known and well-studied medical drugs (MD) containing choline and having neuroprotective properties is citicoline (Recognan). A number of studies have demonstrated the effectiveness of Recognan in relation to mild CI, chronic cerebrovascular diseases (CVD), acute vascular disorders (including post-traumatic genesis). Recognan improves memory and other cognitive functions in healthy young people against the background of asthenia due to stress or increased cognitive and emotional stress or infection, and also has a preventive effect on fading cognitive functions in the process of age-related changes. The duration of neuroprotection can reach 6 months or more - up to 12 months, depending on the patient's condition. Therapy regimens include two-stage Recognan prescribing: with CVD intramuscularly (i/m) at 1000 mg /d for 30 days, in the acute period of ischemic stroke, i/m or intravenously (i/v) at 1000 mg every 12 hours from the first day after diagnosis, 3-5 days after the start of therapy, with preservation functions of swallowing, it is possible to switch to per oral (p/o) drug administration.

Toxidrome of an Easily Obtainable Nootropic: A Case Report of Phenibut Intoxication and Withdrawal Delirium.

PURPOSE/BACKGROUND: Phenibut (4-amino-3-phenyl-butyric acid) is a structural analog of GABA with central nervous system depressant and anxiolytic properties, developed in the former Soviet Union for anxiety, insomnia, and alcohol withdrawal. Its primary mechanism of action is believed to be a GABA-B receptor agonist-with high affinity at the α 2 δ subunit-containing voltage-dependent calcium channels and therefore gabapentinoid activity-as well as, to a lesser extent, GABA-A agonist activity. While not approved or regulated by the FDA, phenibut is easily obtainable online, where it is marketed as a nootropic, or cognitive enhancer. However, phenibut can lead to problems related to intoxication, dependency, and withdrawal, similar to other sedatives. METHODS/PROCEDURES: We present a case of phenibut intoxication and withdrawal delirium that provided diagnostic and management challenges because of a patient that was initially not forthcoming about his phenibut use which resulted in five presentations to the hospital including two admissions. FINDINGS/RESULTS: Initial differential including adrenergic, serotonergic or anticholinergic toxidrome based on clinical picture and history reported at that time, however phenibut use of 50 g daily was eventually revealed, an amount exceeding the highest reported cases in our review of the English literature. IMPLICATIONS/CONCLUSIONS: High-dose phenibut intoxication and withdrawal can appear as dramatic and dangerous as high-dose sedative withdrawal, however given its specified receptor affinity and binding profile we found that a pharmacotherapeutic approach targeting GABA-B, GABA-A, and gabapentenoid receptors were effective in stabilizing this patient, eventually leading to the patient's full and sustained recovery.

[Cognitive impairment and tactics of using the drug Cerebrolysin. Resolution of the International Council of Experts (May 12, 2023)]. / Kognitivnye narusheniya i taktika primeneniya preparata Tserebrolizin. Rezolyutsiya mezhdunarodnogo soveta ekspertov (12 maya 2023 g.).

The aging of the population and the associated increase in the share of cognitive impairments in the structure of a wide range of diseases are a serious challenge for modern healthcare. Difficulties in the treatment of cognitive disorders are determined by many factors, including the age of patients, comorbidity, forced polypragmasia and the adequacy of the dosage of drugs that restore cognitive activity. The experts discussed information about the therapeutic potential of the drug Cerebrolysin in the treatment of cognitive disorders of various origins, stated significant experience of its effective and safe use in many clinical studies in mild and moderate forms of dementia. At the same time, there was a lack of consistent and systematic data on the dosage regimen, frequency, and duration of use of the drug in different forms of cognitive impairment and the degree of their severity. The aim of the international council of experts was to determine the optimal dosage regimens of the drug Cerebrolysin in patients with various etiologies and severity of cognitive impairment. The result of the work was the approval of a unified scheme for the use of the drug Cerebrolysin, considering the severity of the disease and its duration.

Nourishing the Cognition with Millets: A Comprehensive Review of Their Nutritional Impact and Potential as Cognitive Enhancers.

Cognition is the mental processes and abilities involved in acquiring, storing, retrieving and using it for decision making. Cognitive decline due to aging, lifestyle factor, chronic health conditions, genetic, and environmental factors are rising global concern and propose a potential threat to the cognitive health. The nutritional imbalance has led to increase in cognitive disorders around the world. Millets can be a nutritional intervention for promoting cognitive health and preventing cognitive decline. Millets has abundant phenolic compounds, flavonoids, and antioxidants to protect against oxidative stress-induced cognitive impairment. Millets exert neuroprotective effects by modulating pathways involved in neuronal-survival, synaptic-plasticity, and release of brain-derived neurotrophic factor. Millets demonstrates anti-inflammatory properties by regulating inflammatory-pathways and suppressing cytokines associated with cognitive impairment. Millets maintain healthy gut microbiota by producing metabolites such as short-chain fatty acids, which influence brain function and cognition. However, further research is needed to elucidate the underlying mechanisms and on optimizing the proportion do exploit its potential. Implementing millet-based dietary strategies through public health initiatives and educational programs can be a practical approach to support cognitive health across populations. Harnessing the potential of millets as a nutritional intervention offers a promising avenue for promoting cognitive health and improving the quality of life.

Citicoline on the Barthel Index: Severe and moderate brain injury.

INTRODUCTION: Traumatic brain injury (TBI) is a paramount factor in mortality and morbidity. The clinical trials conducted to investigate the efficacy of neuroprotective agents, such as citicoline, as a therapeutic alternative for TBI have presented divergent findings. Therefore, this study aimed to evaluate and compare citicoline's effect on the Barthel Index in patients with severe and moderate brain injury. MATERIALS AND METHODS: The study is a randomized clinical trial. Patients in the case group (35 patients) were treated with citicoline and the control group (34 patients) received a placebo. Data were analyzed using SPSS 16 software. RESULTS: The results showed that changes in the Glasgow Coma Scale, changes in quadriceps muscle force score, Barthel Index score changes, achieving the status without intubation, and spontaneous breathing in patients treated with citicoline were not a statistically significant difference in the two groups (P > 0.05). CONCLUSION: Findings revealed that citicoline did not impact the recovery process of severe and moderate TBI patients.
