Review
OBJECTIVES
It is known that psychotropic medications have an impact on the readings found in Electroencephalogram (EEG). In the field of psychiatry, there are several psychotropics utilized by clinicians. This review seeks to investigate all the available data for psychotropic drugs and their impact on EEG changes.
METHODS
A systematic review of all the published and ongoing literature was conducted via PubMed. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method was used for each search. Key words for searches include 'EEG and Psychotropics', 'EEG and Mood Stabilizers', 'EEG and Clozapine', 'EEG and Bupropion', 'EEG and SSRI', 'EEG and Lamotrigine', 'EEG and Carbamazepine', 'EEG and Lithium' and 'EEG and Valproate', 'EEG and Haloperidol', 'EEG and Aripiprazole', 'EEG and Methylphenidate', 'EEG and Topiramate', 'EEG and Gabapentin' and 'EEG and Oxcarbamazepine'. After applying the inclusion criteria, 201 articles were eligible and reviewed.
RESULTS
Following an extensive review of selected studies from the 201 articles, the studies indicate that each of the psychotropic medications reviewed impact alpha, beta, delta and theta waves independently and differently from each other. Additionally, certain medications, particularly haloperidol and valproic acid, have dissimilar results exemplified in all waveforms.
CONCLUSIONS
This PRISMA systematic review illustrates that while there is available data on psychotropic medications and their proposed effect on EEG activity, further research is needed to confirm these findings to help allow clinical correlations to be made between the patient's response and the psychotropic agent.

Meta-Analysis
The efficacy and safety of metoclopramide in relieving acute migraine attacks compared with other anti-migraine drugs: a systematic review and network meta-analysis of randomized controlled trials.
BACKGROUND
Many drugs are prescribed in relieving acute migraine attacks, we aim to compare metoclopramide with other antimigraine drugs.
METHODS
We searched online databases like PubMed, Cochrane Library, Scopus, and Web of Science till June 2022 for RCTs that compared metoclopramide alone with placebo or active drugs. The main outcomes were the mean change in headache score and complete headache relief. The secondary outcomes were the rescue medications need, side effects, nausea and recurrence rate. We qualitatively reviewed the outcomes. Then, we performed the network meta-analyses (NMAs) when it was possible. which were done by the Frequentist method using the MetaInsight online software.
RESULTS
Sixteen studies were included with a total of 1934 patients: 826 received metoclopramide, 302 received placebo, and 806 received other active drugs. Metoclopramide was effective in reducing headache outcomes even for 24 h. The intravenous route was the most chosen route in the included studies and showed significant positive results regarding headache outcomes; however, the best route whether intramuscular, intravenous, or suppository was not compared in the previous studies. Also, both 10 and 20 mg doses of metoclopramide were effective in improving headache outcomes; however, there was no direct comparison between both doses and the 10 mg dose was the most frequently used dosage. In NMA of headache change after 30 min or 1 h, metoclopramide effect came after granisetron, ketorolac, chlorpromazine, and Dexketoprofen trometamol. Only granisetron's effect was significantly higher than metoclopramide's effect which was only significantly higher than placebo and sumatriptan. In headache-free symptoms, only prochlorperazine was non-significantly higher than metoclopramide which was higher than other medications and showed significantly higher effects only with placebo. In rescue medication, metoclopramide's effect was only non-significantly lower than prochlorperazine and chlorpromazine while its effect was higher than other drugs and showed higher significant effects only than placebo and valproate. In the recurrence rate, studies showed no significant difference between metoclopramide and other drugs. Metoclopramide significantly decreased nausea more than the placebo. Regarding side effects, metoclopramide showed a lower incidence of mild side effects than pethidine and chlorpromazine and showed a higher incidence of mild side effects than placebo, dexamethasone, and ketorolac. The reported extrapyramidal symptoms with metoclopramide were dystonia or akathisia.
CONCLUSION
A dose of 10 mg IV Metoclopramide was effective in relieving migraine attacks with minimal side effects. Compared to other active drugs, it only showed a lower significant effect compared with granisetron regarding headache change while it showed significantly higher effects only with placebo in both rescue medication needs and headache-free symptoms and valproate in only rescue medication need. Also, it significantly decreased headache scores more than placebo and sumatriptan. However, more studies are needed to support our results.

Review
BACKGROUND
Topiramate is a newer broad-spectrum antiepileptic drug (AED). Some studies have shown the benefits of topiramate monotherapy in the treatment of juvenile myoclonic epilepsy (JME). However, there are no current systematic reviews to determine the efficacy and tolerability of topiramate monotherapy in people with JME. This is an updated version of the original Cochrane Review published in Issue 12, 2015.
OBJECTIVES
To evaluate the efficacy and tolerability of topiramate monotherapy in the treatment of JME.
SEARCH METHODS
For the latest update, on 21 February 2017 we searched Cochrane Epilepsy's Specialized Register, CENTRAL, MEDLINE, and ClinicalTrials.gov. We also searched ongoing trials registers, reference lists and relevant conference proceedings, and contacted study authors and pharmaceutical companies.
SELECTION CRITERIA
We included randomized controlled trials (RCTs) investigating topiramate monotherapy versus placebo or other AED treatment for people with JME, with the outcomes of proportion of responders or experiencing adverse events (AEs).
DATA COLLECTION AND ANALYSIS
Two review authors independently screened the titles and abstracts of identified records, selected studies for inclusion, extracted data, cross-checked the data for accuracy and assessed the methodological quality. We performed no meta-analyses due to the limited available data.
MAIN RESULTS
We included three studies with 83 participants. For efficacy, a greater proportion of participants in the topiramate group had a 50% or more reduction in primarily generalized tonic-clonic seizures (PGTCS) compared with participants in the placebo group. There were no significant differences between topiramate versus valproate in participants responding with a 50% or more reduction in myoclonic seizures or in PGTCS or seizure-free. Concerning tolerability, we ranked AEDs associated with topiramate as moderate-to-severe, while we ranked 59% of AEDs linked to valproate as severe complaints. Moreover, systemic toxicity scores were higher in the valproate group than the topiramate group. We judged the quality of the evidence from the studies to be very low.
AUTHORS' CONCLUSIONS
Since the last version of this review we found no new studies. This review does not provide sufficient evidence to support topiramate for the treatment of people with JME. Based on the current limited available data, topiramate seems to be better tolerated than valproate, but there were no more benefits of efficacy in topiramate compared with valproate. In the future, well-designed, double-blind RCTs with large samples are required to test the efficacy and tolerability of topiramate in people with JME.

BACKGROUND AND OBJECTIVE
Psychotropic drugs are a heterogenous group of treatments prescribed for many psychiatric disorders, often for long periods. Their effects on the kidney and its functioning are complex and a source of significant research and debate. This article aims to review recent evidence of the acute and chronic kidney adverse events of diverse psychotropes.
METHODS
A systematic search of randomized controlled trials and large observational studies (n ≥ 100) reporting the effects of psychotropic drugs on the kidney was conducted. The MEDLINE, PsycInfo, and EMBASE databases from 2011 to 2021, inclusive, were broadly searched with few restrictions and no prespecified outcomes. Two or more independent reviewers assessed and summarized all eligible studies, including risks of bias and levels of evidence.
RESULTS
In all, 1999 abstracts were screened for eligibility and 47 articles were included, which examined lithium (33), antiepileptics (10), antipsychotics (13), and antidepressants (9). No studies examining kidney adverse effects of other psychotropes, such as benzodiazepines, met inclusion criteria. Study populations were adult (8), geriatric (9), and mixed (30). Lithium was almost unanimously associated with (1) chronic kidney disease and (2) nephrogenic diabetes insipidus in methodologically diverse studies. The most supported risk factors for declining kidney functioning with lithium were advanced age, duration of lithium treatment, acute lithium toxicity, female sex, medications with known renal interactions, diabetes mellitus/hyperglycemia, and overall medical comorbidity. Supratherapeutic lithium concentrations are both the causes and consequences of acute kidney injury. Once significant chronic kidney disease has developed, four studies found that replacing lithium with other mood stabilizers does not slow progression, and the evolution to end-stage kidney disease is rare overall with modern practices. Compared to lithium, fewer studies examined antipsychotics and antiepileptics but found relatively less direct kidney harms. Antidepressants were not associated with acute or chronic kidney harms.
CONCLUSIONS
Despite the heterogeneity of findings, owing to varying methodologies and research challenges, recent studies strongly suggest that lithium is associated with an increased risk of chronic kidney disease and nephrogenic diabetes insipidus, especially in older adults and long-term lithium users. Clinicians should balance the harms of lithium against its established benefits, and ensure adequate monitoring and management of comorbidities in all patients. Weaker evidence suggests that antiepileptics such as valproate and antipsychotics result in comparatively less harm to the kidney than lithium, but warrant monitoring because of multiple direct and indirect mechanisms for potential kidney adverse events. Antidepressants do not have clear kidney adverse effects and appear safe (though potentially less effective) in the setting of kidney disease. Other classes of psychotropic drugs have received little research interest. Further research is warranted, particularly into specific antiepileptics and antipsychotics, and careful attention should be paid to mitigating important sources of bias such as confounding by indication.

Review
There are numerous potential factors that may affect growth in children with epilepsy, and these must be evaluated in any child with appetite and weight concerns. Antiseizure medications (ASMs) have potential adverse effects, and many may affect appetite, thus impacting normal growth and weight gain. The aim of this review is to focus on the impact of both epilepsy and ASMs on appetite and weight in children. We systematically reviewed studies using Medline assessing the impact of ASMs on appetite and weight in children. Eligible studies included randomized controlled trials and open-label studies (open-label extension and interventional) that targeted or included the pediatric population (0-18 years of age). Each study was classified using the American Academy of Neurology (AAN) Classification of Evidence for Therapeutic Studies, and the level of evidence for impact on appetite and weight in children was graded. ASMs associated with decreased appetite and/or weight loss include fenfluramine, topiramate, zonisamide, felbamate, rufinamide, stiripentol, cannabidiol, brivaracetam and ethosuximide; ASMs with minimal impact on weight and appetite in children include oxcarbazepine, eslicarbazepine, lamotrigine, levetiracetam, lacosamide, carbamazepine, vigabatrin and clobazam. The ASM most robustly associated with increased appetite and/or weight gain is valproic acid; however, both pregabalin and perampanel may also lead to modest weight gain or increased appetite in children. Certain ASMs may impact both appetite and weight, which may lead to increased morbidity of the underlying disease and impaired adherence to the treatment regimen.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterised by repetitive behaviours, cognitive rigidity/inflexibility, and social-affective impairment. Unfortunately, few pharmacological treatments exist to alleviate these socio-behavioural impairments. Prenatal administration of valproic acid (VPA) has become an accepted animal model of ASD and has been extensively used to explore new pharmacotherapies in rodents. We conducted a systematic review of the behavioural impairments induced by the VPA model in rodents, with specific reference to 3 core socio-behavioural alterations associated with ASD: repetitive behaviours, cognitive rigidity/inflexibility, and social-affective impairment. We systematically reviewed studies attempting to alleviate these core behavioural alterations using pharmacological means. We include 132 studies exploring the prenatal effects of VPA in rodents. Gestational exposure to VPA in rodents has significant effects on rodent-equivalent measures of the 3 core behavioural traits characteristic of ASD in humans, inducing social impairments, repetitive behaviour, and cognitive rigidity/inflexibility after birth. This model's validity has seen it used to test potential drug treatments for ASD and is likely to continue doing so. We conclude the rodent VPA model may be suitable to examine future therapeutic interventions for ASD, providing an overview of the progress made so far.

BACKGROUND
Current guidelines recommend therapeutic drug monitoring as a critical component of valproic acid (VPA) therapy. Due to high protein binding, the active unbound (free) portion of VPA can be misrepresented by total VPA serum levels in certain clinical scenarios. Monitoring free VPA serum levels may be warranted when assessing the clinical response to VPA therapy.
OBJECTIVES
The aims were to conduct a systematic review to identify a therapeutic range for free VPA serum levels; to explore the correlation of free VPA serum levels with clinical toxicity and therapeutic benefit; and to examine predictors of discordance between free and total VPA levels.
METHODS
Medline, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), PsycINFO, BIOSIS Previews, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) were searched from the time of database inception to June 20, 2021. Randomized controlled trials and observational studies that evaluated any patient receiving VPA with free VPA level monitoring were included.
RESULTS
Of 189 citations, we identified 27 relevant studies, which included 14 observational studies, two case series, and 11 case reports. Three studies provided a therapeutic range for free VPA levels between 20 and 410 μmol/L. Two studies suggested the occurrence of hyperammonemia and thrombocytopenia at free VPA serum levels above 60 µmol/L and 103.3 µmol/L, respectively. Two studies suggested an upper limit for neurotoxicity at free VPA serum levels of 70 µmol/L and 207.9 µmol/L. Hypoalbuminemia was identified as a predictor of therapeutic discordance.
CONCLUSIONS
This review demonstrates a paucity of data informing the clinical utility of free VPA serum levels. Further high-quality trials are needed to validate an optimal therapeutic range for free VPA levels.

Review
BACKGROUND
We systematically reviewed the existing literature on the cosmetic adverse effects of antiseizure medications (ASMs) in order to depict a clear picture of these unwanted side effects of ASMs with a particular attention to hair loss, hirsutism, acne, and gingival hyperplasia.
METHODS
This systematic review was prepared according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Scopus, MEDLINE, and Google Scholar from the inception to 25 March, 2021 were systematically searched. These key words (title/abstract) were used: "hair loss" OR "hirsutism" OR "acne" OR "gingival hyperplasia" AND "seizure" OR "epilepsy" OR "anriseizure" OR "antiepileptic". The exclusion criteria included: non-original studies, articles not in English, and animal studies.
RESULTS
The primary search yielded 3938 studies; 127 studies were related to the topic and were included in the current systematic review. The most robust evidence on cosmetic adverse effects of ASMs were related to phenytoin (causing gingival hyperplasia, hirsutism, and acne) and valproate (causing hair loss and hirsutism); however, many other ASMs were also implicated in causing these cosmetic adverse effects.
CONCLUSION
Antiseizure medications may be associated with various cosmetic adverse effects. Phenytoin and valproate are the most notorious ASMs in this regard; but, other ASMs have also been implicated in causing hair loss, hirsutism, acne, and gingival hyperplasia. Physicians should pay more attention to these significant adverse effects that may affect a patient's facial attractiveness, quality of life, and emotional state.

We aimed to determine the efficacy of the various available oral, topical, and procedural treatment options for hair loss in individuals with androgenic alopecia. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic review of the National Library of Medicine was performed. Overall, 141 unique studies met our inclusion criteria. We demonstrate that many over the counter (e.g. topical minoxidil, supplements, low-level light treatment), prescription (e.g. oral minoxidil, finasteride, dutasteride), and procedural (e.g. platelet-rich plasma, fractionated lasers, hair transplantation) treatments successfully promote hair growth, highlighting the superiority of a multifaceted and individualized approach to management.

Review
Mood stabilizers such as lithium and anticonvulsants are still standard-of-care for the acute and long-term treatment of bipolar disorder (BD). This systematic review aimed to assess the prevalence of their adverse effects (AEs) and to provide recommendations on their clinical management. We performed a systematic research for studies reporting the prevalence of AEs with lithium, valproate, lamotrigine, and carbamazepine/oxcarbazepine. Management recommendations were then developed. Mood stabilizers have different tolerability profiles and are eventually associated to cognitive, dermatological, endocrine, gastrointestinal, immunological, metabolic, nephrogenic, neurologic, sexual, and teratogenic AEs. Most of those can be transient or dose-related and can be managed by optimizing drug doses to the lowest effective dose. Some rare AEs can be serious and potentially lethal, and require abrupt discontinuation of medication. Integrated medical attention is warranted for complex somatic AEs. Functional remediation and psychoeducation may help to promote awareness on BD and better medication management.
