The formation of memories is a complex, multi-scale phenomenon, especially when it involves integration of information from various brain systems. We have investigated the differences between a novel and consolidated association of spatial cues and amphetamine administration, using an in situ hybridisation method to track the short-term dynamics during the recall testing. We have found that remote recall group involves smaller, but more consolidated groups of neurons, which is consistent with their specialisation. By employing machine learning analysis, we have shown this pattern is especially pronounced in the VTA; furthermore, we also uncovered significant activity patterns in retrosplenial and prefrontal cortices, as well as in the DG and CA3 subfields of the hippocampus. The behavioural propensity towards the associated localisation appears to be driven by the nucleus accumbens, however, further modulated by a trio of the amygdala, VTA and hippocampus, as the trained association is confronted with test experience. Moreover, chemogenetic analysis revealed central amygdala as critical for linking appetitive emotional states with spatial contexts. These results show that memory mechanisms must be modelled considering individual differences in motivation, as well as covering dynamics of the process.

Research has shown that external focus (EF) instructions-directing attention to intended movement effects (e.g., ball's or dart's path)-are more effective for enhancing motor performance and learning than internal focus (IF) instructions, which focus on body movements (e.g., arm or foot motion). Nonetheless, the impact of visuospatial working memory capacity (WMC) in this context, especially among children, has been less investigated. This research sought to examine the effects of EF compared to IF on the skill acquisition and motor learning of a dart-throwing task among children with both high and low visuospatial WMC. Forty-eight boys aged 9-11 (Mage: 9.67 ± 0.76 years) were grouped by high or low WMC based on spatial span and memory tests, then assigned to receive either EF or IF instructions. The experiment comprised three stages: practice, retention, and two transfer tests, including throwing from a longer distance and a dual-task scenario with added cognitive load (tone counting). Results showed that EF outperformed IF at all stages. While WMC did not affect performance during practice and retention, children with low WMC performed better than those with high WMC during the longer distance test. In dual-task conditions, an EF continued to surpass an IF, whilst the WMC exerted no significant impact. The present findings suggest that an EF relative to an IF promotes more automatic movement and enhanced multitasking, while the impact of visuospatial WMC was less than expected, highlighting the benefits of EF in teaching motor skills to children, regardless of visuospatial WMC.

Pochopení vztahu mezi senzomotorickými proměnnými a exerkiny, které ovlivňují funkci mozku a kognici, nám umožňuje hlouběji porozumět biologickému procesu stárnutí. Hlavním cílem této studie bylo zjistit, jak silně jsou mozkový neurotrofický faktor (brain-derived neurotrophic factor, BDNF), irisin, svalová hmota a svalová síla asociovány s výsledky testů vybraných kognitivních funkcí u starších žen a jak dobře je predikují. Padesát sedm starších žen (průměrný věk 70,4 ± 4,1 roku) absolvovalo baterii neuropsychologických testů, měření izometrické dynamometrie a bioelektrické impedance. Hladiny v krevním séru sledovaných exerkinů byly stanoveny enzymatickým imunosorbentním testem (ELISA). Pro testování predikcí byly využity hierarchické vícenásobné regresní modely. Odhadli jsme, že rozptyl 46,1 % v krátkodobé paměti byl zapříčiněn hladinami BDNF v séru, přičemž druhým statisticky významným prediktorem byl věk (beta = –0,22; p = 0,030). Síla dolních končetin (lower limb strength, LLS) prokázala významnou prediktivní sílu jak u paměti – bezprostřední vybavení (beta = 0,39; p = 0,004), tak u paměti – oddálené vybavení (beta = 0,45; p = 0,001). Hladiny BDNF v séru byly významným prediktorem u oddáleného vybavení (beta = 0,29; p = 0,048). Přidání hladin BDNF do modelu prokázalo významné zvýšení jeho prediktivní síly o přibližně 5,6 % (p = 0,048) u paměti – oddálené vybavení. Index kosterní svalové hmoty (skeletal muscle index, SMI) a úroveň vzdělání byly významnými prediktory mentální flexibility. Byla zjištěna silná pozitivní asociace mezi hladinami BDNF, irisinem, svalovou silou a kognitivní funkcí, přičemž irisin a svalová síla jsou silnými prediktory hladin BDNF u starších žen. Studie byla realizována s podporou grantu Univerzity Karlovy – PRIMUS/19/HUM/012, Specifického vysokoškolského výzkumu SVV 260599, projektu COOPERATIO a Grantové agentury UK číslo grantu 268321.

Understanding the relationship between sensorimotor variables and exerkines related to brain function and cognition may help better understand biological ageing. The main aim of this study was to determine how strongly brain-derived neurotrophic factor (BDNF), irisin, muscle mass and muscle strength are associated and predict scores on selected cognitive domain tests in older women. Fifty seven older women (mean age 70.4 ± 4.1 years) underwent a battery of cognitive and psychological tests and measurements of isometric dynamometry and bioelectrical impedance. Serum exerkines levels were measured by enzyme-linked immunosorbent assay (ELISA). Hierarchical multiple regression models were used to test the predictions. We estimated that 46.1% of the variance in short-term memory was accounted for by serum BDNF levels, with age being the second statistically significant predictor (Beta = -0.22; p = 0.030). Lower limb strength (LLS) showed significant predictive power in both immediate (Beta = 0.39; p = 0.004) and delayed memory (Beta = 0.45; p = 0.001), serum BDNF levels were a significant predictor in delayed memory (Beta = 0.29; p = 0.048). Adding serum BDNF levels to the model showed a significant increase in predictive power of approximately 5.6% (p = 0.048) in delayed memory. Skeletal muscle index (SMI) and education level were significant predictors of mental flexibility. A strong positive association between BDNF levels, irisin, muscle strength, and cognitive function was found, with irisin and muscle strength being strong predictors of BDNF levels in older women.

BACKGROUND: Semantic and short-term episodic memory are impaired in some brain disorders including Alzheimer's disease. OBJECTIVE: Development and validation of an almost self-administered, but cognitively demanding four-minute test identifying very mild cognitive impairment (vMCI). METHODS: The innovative hedgehog PICture Naming and Immediate Recall (PICNIR) consisted of two parts. The first task was to write down the names of 20 black-and-white pictures to evaluate long-term semantic memory and language. The second task involves immediate recall and writing the names of as many previously named pictures as possible in one minute. The PICNIR is assessed using the number of naming errors (NE) and correctly recalled picture names (PICR). The PICNIR and a neuropsychological battery were administered to 190 elderly individuals living independently in the community. They were divided into those with vMCI (n = 43 with Montreal Cognitive Assessment (MoCA) 24 ± 3 points) and sociodemographically matched cognitively normal (CN) individuals (n = 147 with MoCA 26 ± 3). Both subgroups had predicted mean Mini-Mental State Examination scores of 28-29 points. RESULTS: Compared to CN, vMCI participants made more NE (0.3 ± 0.6 versus 0.6 ± 0.9; p = 0.02) and recalled fewer PICR (8.9 ± 2.2 versus 6.8 ± 2.2; p < 0.000001). Discriminative validity was satisfactory using the area under the ROC curve (AUC): 0.76 for PICR, 0.74 for MoCA, 0.67 for MoCA-five-word recall, and 0.59 for NE. The AUCs of PICR and MoCA were comparable and larger than those of MoCA five-point recall or NE. Logical Memory scores, RAVLT scores, Digit symbol, and animal fluency correlated with PICR. CONCLUSIONS: The picture-based PICNIR is an ultra-brief, sensitive cognitive test valid for assessing very mild cognitive impairment. Its effectiveness should be validated for other languages and cultures.

The relationship between working memory (WM) and neuronal oscillations can be studied in detail using brain stimulation techniques, which provide a method for modulating these oscillations and thus influencing WM. The endogenous coupling between the amplitude of gamma oscillations and the phase of theta oscillations is crucial for cognitive control. Theta/gamma peak-coupled transcranial alternating current stimulation (TGCp-tACS) can modulate this coupling and thus influence WM performance. This study investigated the effects of TGCp-tACS on WM in older adults and compared their responses with those of younger participants from our previous work who underwent the same experimental design. Twenty-eight older subjects underwent both TGCp-tACS and sham stimulation sessions at least 72 h apart. Resting-state electroencephalography (EEG) was recorded before and after the interventions, and a WM task battery with five different WM tasks was performed during the interventions to assess various WM components. Outcomes measured included WM task performance (e.g., accuracy, reaction time (RT)) and changes in power spectral density (PSD) in different frequency bands. TGCp-tACS significantly decreased accuracy and RT on the 10- and 14-point Sternberg tasks and increased RT on the Digit Symbol Substitution Test in older adults. In contrast, younger participants showed a significant increase in accuracy only on the 14-item Sternberg task. Electrophysiological analysis revealed a decrease in delta and theta PSD and an increase in high gamma PSD in both younger and older participants after verum stimulation. In conclusion, theta-gamma coupling is essential for WM and modulation of this coupling affects WM performance. The effects of TGCp-tACS on WM vary with age due to natural brain changes. To better support older adults, the study suggests several strategies to improve cognitive function, including: Adjusting stimulation parameters, applying stimulation to two sites, conducting multiple sessions, and using brain imaging techniques for precise targeting.

Psychiatric and mood disorders may play an important role in the development and persistence of irritable bowel syndrome (IBS). Previously, we hypothesized that stress-induced implicit memories may persist throughout life via epigenetic processes in the enteric nervous system (ENS), independent of the central nervous system (CNS). These epigenetic memories in the ENS may contribute to developing and perpetuating IBS. Here, we further elaborate on our earlier hypothesis. That is, during pregnancy, maternal prenatal stresses perturb the HPA axis and increase circulating cortisol levels, which can affect the maternal gut microbiota. Maternal cortisol can cross the placental barrier and increase cortisol-circulating levels in the fetus. This leads to dysregulation of the HPA axis, affecting the gut microbiota, microbial metabolites, and intestinal permeability in the fetus. Microbial metabolites, such as short-chain fatty acids (which also regulate the development of fetal ENS), can modulate a range of diseases by inducing epigenetic changes. These mentioned processes suggest that stress-related, implicit, long-term epigenetic memories may be programmed into the fetal ENS during pregnancy. Subsequently, this implicit epigenetic stress information from the fetal ENS could be conveyed to the CNS through the bidirectional microbiota-gut-brain axis (MGBA), leading to perturbed functional connectivity among various brain networks and the dysregulation of affective and pain processes.

Working memory (WM) is essential for the temporary storage and processing of information required for complex cognitive tasks and relies on neuronal theta and gamma oscillations. Given the limited capacity of WM, researchers have investigated various methods to improve it, including transcranial alternating current stimulation (tACS), which modulates brain activity at specific frequencies. One particularly promising approach is theta-gamma peak-coupled-tACS (TGCp-tACS), which simulates the natural interaction between theta and gamma oscillations that occurs during cognitive control in the brain. The aim of this study was to improve WM in healthy young adults with TGCp-tACS, focusing on both behavioral and neurophysiological outcomes. Thirty-one participants completed five WM tasks under both sham and verum stimulation conditions. Electroencephalography (EEG) recordings before and after stimulation showed that TGCp-tACS increased power spectral density (PSD) in the high-gamma region at the stimulation site, while PSD decreased in the theta and delta regions throughout the cortex. From a behavioral perspective, although no significant changes were observed in most tasks, there was a significant improvement in accuracy in the 14-item Sternberg task, indicating an improvement in phonological WM. In conclusion, TGCp-tACS has the potential to promote and improve the phonological component of WM. To fully realize the cognitive benefits, further research is needed to refine the stimulation parameters and account for individual differences, such as baseline cognitive status and hormonal factors.

Elektrokonvulzívna terapia (ECT) má v psychiatrii svoje stále miesto a nezastupiteľnú úlohu v liečbe závažných psychických porúch. Výskyt vážnejších nežiaducich účinkov je zriedkavý, mortalita ECT je nižšia, v porovnaní s inými lekárskymi zákrokmi realizovanými v celkovej anestéze. V súvislosti s ECT sa popisujú rôzne poruchy kognitívnych funkcií, ktoré predstavujú riziko z hľadiska negatívneho vplyvu na kvalitu života pacienta. Obavy z ich výskytu a údajnej vysokej závažnosti dlhodobo pretrvávajú v laickej verejnosti. Jedná sa o tzv. nesystematický prehľad. Literárne zdroje boli čerpané najmä z databázy PubMed (metaanalýzy, systematické prehľadové práce a klinické štúdie, publikované na danú tématiku v priebehu posledných 10 rokov). Podľa nedávnej a pomerne rozsiahlej metaanalýzy bol výskyt subjektívnych kognitívnych nežiaducich účinkov u pacientov po ECT zaznamenaný v 48 % prípadov. Podľa aktuálne dostupných údajov sú však väčšinou prechodné, krátkodobé a týkajú sa len určitých kognitívnych domén (rýchlosť spracovania informácií, exekutívne funkcie, pozornosť, pracovná a verbálna pamäť, autobiografická pamäť). Napriek tomu porucha autobiografickej pamäti môže pretrvávať v niektorých prípadoch aj viac ako 1 rok s parciálnou ireverzibilitou. Na výskyt kognitívnych nežiaducich účinkov má vplyv viacero modifikovateľných faktorov, ktoré je potrebné poznať a rešpektovať. Podstatným z nich je individualizácia množstva aplikovaného elektrického náboja počas ECT prostredníctvom jeho postupnej titrácie, za účelom nájdenia individuálneho záchvatového prahu. Jednoznačne by mali byť uprednostňované ultrakrátke impulzy (0,3ms) pred dlhšími. Ak to klinický stav umožní, je vhodné použiť unilaterálne umiestnenie elektród (nad nedominantnou hemisférou). Neodporúča sa podávanie viac ako 12 aplikácií v jednej sérii v akútnej fáze liečby (pri bitemporálnom umiestnení elektród). Individuálne faktory pacienta, ku ktorým sa radia vyšší vek, ženské pohlavie, prítomnosť organického poškodenia mozgu a nižší intelekt, predstavujú vyššie riziko rozvoja kognitívnych nežiaducich účinkov po ECT, rovnako aj súbežná liečba lítiom počas ECT. Súčasné národné a medzinárodné odporúčania ponúkajú rôzne psychometrické inštrumenty na monitorovanie kognitívnych nežiaducich účinkov ECT. V niektorých krajinách, napríklad v nemecky hovoriacich regiónoch, ale ani na Slovensku, konkrétne odporúčania neboli vypracované. V dnešnej dobe existujú batérie testov hodnotiace relevantné kognitívne domény, ktoré je možné pri ECT použiť v klinickej praxi, pretože nie sú časovo ani odborne náročné na administráciu. Jedná sa napr. o ECCA test (ElectroConvulsive therapy Cognitive Assessment), prípadne o batériu B4ECT-ReCoDe (Battery for ECT Related Cognitive Deficits). Komplikáciou ich využitia v podmienkach Slovenskej i Českej republiky je, že tam nie sú štandardizované. Alternatívou je použitie jednotlivých testov na spomenuté domény. Významné je najmä hodnotenie dĺžky dezorientácie pacienta po ECT zákrokoch, vyhodnocovanie autobiografickej pamäti, schopnosti verbálneho učenia, exekutívnych funkcií a rýchlosti spracovania informácií a pozornosti, resp. pracovnej pamäti. Hodnotenie výskytu a závažnosti kognitívnych nežiaducich účinkov u pacientov podstupujúcich ECT je v praxi potrebné, zníži riziko rozvoja ich závažnejšieho stupňa, prispeje k optimalizácii liečby, ako aj k zlepšeniu spolupráce pacientov pri tejto terapii.
Electroconvulsive therapy (ECT) has a solid place in psychiatry and an irreplaceable role in the treatment of serious mental disorders. The occurrence of serious side effects is rare, the mortality rate of ECT is lower, compared to other medical interventions performed under general anesthesia. In connection with ECT, various disorders of cognitive functions are described, which pose a risk in terms of a negative impact on the patient ́s quality of life. Concerns about their occurrence and alleged high severity persist for a long time in the public. This is the so-called unsystematic review. Literary sources were mainly drawn from the PubMed database (meta-analyses, systematic review works and clinical studies published on the given topic during the last 10 years). According to a recent and fairly extensive meta-analysis, the occurrence of subjective cognitive side effects in patients after ECT was recorded in 48% of cases. However, according to the currently available data, they are mostly transitory, short-term and affect only certain cognitive domains (information processing speed, executive functions, attention, working and verbal memory, autobiographical memory). Nevertheless, the autobiographical memory disorder can persist in some cases for more than 1 year with partial irreversibility. The occurrence of cognitive side effects is influenced by several modifiable factors that need to be known and respected. An essential one is the individualization of the amount of applied electric charge during ECT through its gradual titration, in order to find the individual seizure threshold. Ultrabrief pulses (0.3ms) should clearly be preferred over longer ones. If the clinical condition allows it, it is advisable to use unilateral electrode placement (over the non-dominant hemisphere). It is not recommended to administer more than 12 applications in one series in the acute phase of treatment (with bitemporal placement of electrodes). Individual patient factors such as older age, female gender, presence of organic brain damage, and lower intellect pose a higher risk of developing cognitive adverse effects after ECT. So does concurrent lithium treatment during ECT. Current national and international guidelines offer various psychometric instruments to monitor the cognitive side effects of ECT. In some countries, for example in German-speaking regions, but also in Slovakia, specific recommendations have not been developed. Nowadays, there are batteries of tests evaluating relevant cognitive domains that can be used in clinical practice during ECT, because they are neither time nor expertly hard to administer. It is, for example, the ECCA test (ElectroConvulsive therapy Cognitive Assessment), or the B4ECT-ReCoDe battery (Battery for ECT Related Cognitive Deficits). The complication of their use in the conditions of Slovakia and the Czech Republic is that they are not standardized there. An alternative is to use individual tests for the mentioned domains. It is particularly important to assess the length of the patient ́s disorientation after ECT procedures, the evaluation of autobiographical memory, verbal learning ability, executive functions and information processing speed and attention, or working memory. Assessment of the occurrence and severity of cognitive side effects in patients undergoing ECT is necessary in practice, it will reduce the risk of developing their more severe degree, contribute to the optimization of treatment, as well as to the improvement of patient cooperation in this therapy.
PURPOSE: Memory plays an essential role in daily life and is one of the first functions to deteriorate in cognitive impairment and dementia. Transcutaneous vagus nerve stimulation (tVNS) is a promising therapeutic method; however, its ability to enhance memory is underexplored, especially considering long-term stimulation. We aimed to investigate the effect of a 2-week course of auricular tVNS (taVNS) on memory in a non-clinical population. METHODS: This single-blind randomized placebo-wait-list controlled trial recruited 76 participants (30 men; mean age 48.32 years) and randomized them into four groups: early active/sham taVNS and late active/sham taVNS. Participation in the study lasted 4 weeks; early groups underwent 2 weeks intervention immediately following the first study site visit (days 0-13) and late groups 2 weeks after the first study site visit (days 14-27). Active and sham taVNS included 2 weeks of daily 4-h neurostimulation at the tragus or earlobe, respectively. To assess memory, we used the Rey Auditory Verbal Learning Test. RESULTS: Two weeks of active taVNS, but not sham taVNS, improved immediate recall and short-term memory score both in early and late groups. Furthermore, the improvements persisted over subsequent follow-up in early active taVNS. Importantly, the effect of active taVNS was superior to sham for immediate recall in both early and late groups. There were no statistical differences in delayed recall. CONCLUSION: Our findings suggest that taVNS has potential to improve memory, particularly immediate recall, and may be an effective method in preventing memory loss and mitigating cognitive aging.

Srdeční infarkt je závažný stav definovaný jako nekróza části srdečních buněk (kardiomyocytů) s klinickými známkami akutní ischemie myokardu. Většinou je charakterizován rupturou aterosklerotického plátu, ulcerací, fisurou nebo erozí s výsledným intraluminálním trombem v jedné nebo více koronárních tepnách. Srdeční infarkt bývá spojován s vyšším věkem a u mladých pacientů se na tuto diagnózu často nemyslí. Cílem sdělení je poukázat na výskyt akutního infarktu myokardu (AIM) u mladých jedinců. Rádi bychom demonstrovali závažnost problematiky diagnostiky AIM u mladých nemocných na kazuistice muže věku 36 let s pozitivní rodinnou anamnézou. Na naše pracoviště byl přivezen za kontinuální resuscitace zevním masážním systémem Lucas pro refrakterní srdeční zástavu s obrazem bezpulzové aktivity. Resuscitace byla nakonec úspěšná, k obnově spontánního oběhu došlo v 85. minutě. Následně byl na EKG obraz infarktu myokardu s ST elevacemi přední stěny. Akutní koronarografie potvrdila proximální uzávěr ramus interventricularis anterior, byla provedena balónková angioplastika s implantací stentu. Tento mladý muž opustil naše oddělení po 21 dnech s malým neurologickým deficitem (porucha krátkodobé paměti). Prevalence srdečního infarktu stoupá s věkem, ale může se vyvinout a ohrožovat život i u mladých jedinců. Proto je třeba na tuto diagnózu myslet také u mladších pacientů s námahovými bolestmi na hrudi nebo v zádech
A heart attack is a serious condition, defined as the death of a portion of cardiac muscle cells. It is typically caused by a sudden blockage or significant narrowing of a coronary artery that supplies the affected region. Although heart attacks are often associated with older individuals, they can also occur in the young. The aim of this paper is to shed light on the incidence of acute myocardial infarction (AMI) in younger populations. Through the case study of a 36year-old male with a familial history of heart conditions, we aim to highlight the critical nature of early AMI diagnosis in young individuals. He was admitted to our department while undergoing continuous resuscitation using the Lucas external chest compression system, following a refractory cardiac arrest characterized by pulseless electrical activity. Resuscitation proved successful, with spontaneous circulation restored after 85 minutes. A subsequent ECG revealed an ST elevation myocardial infarction of the anterior wall. Acute coronary angiography identified a proximal blockage in the ramus interventricularis anterior, which was then treated with balloon angioplasty and stent implantation. Twenty-one days later, the young patient was discharged with a mild impairment in short-term memory. While the prevalence of myocardial infarction increases with age, it is imperative to recognize that younger individuals are not immune. Therefore, healthcare professionals must consider AMI as a potential diagnosis in younger patients presenting with exertional chest or back pain.
