    Opis:
    Introduction. Basal ganglia calcification (BGC) in pediatric population is rare and is considered as a pathological finding. Various causes may be responsible for BGC including hypoparathyroidism, various infectious, toxicities or hereditary disorders. Aim. We aimed to present a 8 year old boy presented with generalized seizure and bilateral small amount of globus pallidum calcifications on neuroimaging studies leading to the diagnosis of idiopathic hypoparathyroidism, which is a treatable cause of seizure. Description of the case. A 8-year-old boy presented to our emergency department with generalized seizure for the first time in his life. There was no history of previous head trauma and his family history was unremarkable. Neurological examination revealed no pathological findings. Radiological imaging studies revealed only bilateral small amount of globus pallidus calcifications. He was referred to the pediatric endocrinology department for further evaluation of the hypocalcemic convulsion, where laboratory investigations revealed idiopathic hypoparathyroidism as the cause of hypocalcemic convulsion with exclusion of the other causes. Conclusion. Even a small amount of BGC in pediatric patients may be the sign of primary hypoparathyroidism and should be evaluated with serum electrolyte levels for early diagnosis and for the prevention of multisystemic complications of hypoparathyroidism.

    Opis:
    Introduction and aim. Non-ketotic hyperglycemia (NKHG), also known as hyperosmolar hyperglycemic state (HHS) is a serious metabolic complication of diabetes mellitus (DM).The mortality rate can be up to 20% and this is much more higher than that of diabetic ketoacidosis (DKA). It is usually precipitated by an event such as pulmonary/urinary infection, myocardial infarction (MI) or stroke. In this state of metabolic derangements, central nervous system (CNS) manifestations including altered mental status with or without focal neurological deficits are prominent clinical presentations. On the other hand, HHS may also be complicated with various other CNS events. Herein, a quite rare presentation of HHS with hemichorea ‒ hemiballismus in a 71 year old female patient with type 2 DM is presented. Description of the case. A 71-year-old female patient type 2 DM presented to our emergency department with progressive involuntary movements on the right upper and lower extremities accompanied by semiconsciousness during the last 24 hours. On neurological examination, cranial nerves and cerebellar signs were found to be normal, as the deep tendon reflexes. However, involuntary non-rhythmic writhing movements at rest were present on her right sided extremities. The fingerstick evaluation showed marked hyperglycemia (HG). The laboratory findings were characterized with high blood glucose level without obvious acidosis compatible with HHS. In urine analysis, glucosuria without significant ketonuria was detected. On head CT, subtle hyperdensity was noted in the left neostriatal regions without any mass effect or perilesional edema, compatible with left sided diabetic striatopathy (DS). Conclusion. Diabetic striatopathy is a quite rare presentation of HHS with hemichorea – hemiballismus. The characteristic computed tomograhy (CT) findings of associated striatopathy should be differentiated from vascular lesions that may also present with unilateral findings in the course of HHS and should not be overlooked in diabetic patients to recognise the ongoing HHS before the coma precedes.

    Opis:
    The subcortical structures form the middle part of the central nervous system. They create systems which are some kind of basis for performing intentional tasks with the cooperation of the cortical centers. So the extrapyramidal system provides the fluid motion by the unconscious influence on the muscle tone distribution. However, the cooperation with the pyramidal system and the cerebellum is necessary for the performance of intentional tasks. The limbic system is formed by the grey matter structures which are engaged in the control of memory and learning processes. The major transmission station for the sensory information creates the thalamus which is connected with the extrapyramidal and limbic system. The organism adaptation to the changeable external conditions is provided by the hypothalamus involving many chemoreceptors of grey matter nuclei. It supplies internal balance and the equilibrium of body fluids, making use of the antagonism of the centers located there.Key words: extrapyramidal system, basal ganglia, diencephalon, autonomous system, limbic system

    Opis:
    Objectives Veterans of the 1991 Gulf War (GW) were exposed to a myriad of potentially hazardous chemicals during deployment. Epidemiological data suggest a possible link between chemical exposures and Parkinson’s disease (PD); however, there have been no reliable data on the incidence or prevalence of PD among GW veterans to date. This study included the following 2 questions: 1. Do deployed GW veterans display PD-like symptoms? and 2. Is there a relationship between the occurrence and quantity of PD-like symptoms, and the levels of deployment-related exposures in GW veterans? Material and Methods Self-reports of symptoms and exposures to deployment-related chemicals were filled out by 293 GW veterans, 202 of whom had undergone 3 Tesla volumetric measurements of basal ganglia volumes. Correlation analyses were used to examine the relationship between the frequency of the veterans’ self-reported exposures to deployment-related chemicals, motor and non-motor symptoms of PD, and the total basal ganglia volumes. Results Healthy deployed GW veterans self-reported few PD-like non-motor symptoms and no motor symptoms. In contrast, GW veterans with Gulf War illness (GWI) self-reported more PD-like motor and non-motor symptoms, and more GW-related exposures. Compared to healthy deployed veterans, those with GWI also had lower total basal ganglia volumes. Conclusions Although little is known about the long-term consequences of GWI, findings from this study suggest that veterans with GWI show more symptoms as those seen in PD/prodromal PD, compared to healthy deployed GW veterans.

    Opis:
    In this paper, we introduce several system theoretic problems brought forward by recent studies on neural models of motor control. We focus our attention on three topics: (i) the cerebellum and adaptive control, (ii) reinforcement learning and the basal ganglia, and (iii) modular control with multiple models. We discuss these subjects from both neuroscience and systems theory viewpoints with the aim of promoting interplay between the two research communities.

    Opis:
    Introduction: Movement disorders in the form of involuntary movements are a rare complication of stroke, found in approximately 4% of patients. Material and methods: This case is presented on the basis of medical records of the patient. Case study: This paper presents the case of a 73-year-old patient with chronic obstructive pulmonary disease, a history of an ischaemic stroke, who was treated repeatedly at the Department of Neurology due to poststroke involuntary movements involving the left upper extremity, head and tongue. Computed tomography of the head revealed: bilateral vascular focal lesions in the projection of basal ganglia. Frequently, the decrease in oxygen saturation (SpO2) levels below 90% was observed in the patient, when involuntary movements intensified. When the patient was saturated with oxygen, involuntary movements were remitted, and reappeared after some time but their amplitude was significantly narrower. Involuntary movements completely regressed after new cerebral ischaemic accidents in the right frontal lobe. Results and discussion: Chorea-ballism and dystonic movements are associated with damage to the basal ganglia, most commonly developed as a result of lesions of a vascular origin. In the case of our patient, vascular lesions were confirmed by a computed tomography scan. Conclusions: In the presented case massive involuntary movements intensified when saturation levels dropped below 90%. This can be associated with the adverse effect of hypoxia in focal ischaemia involving the brain. Remission of involuntary movements may have been caused by the development of a new ischaemic lesion in the right frontal lobe.
    Wstęp: Ruchy mimowolne są rzadkim objawem udaru mózgu, występującym u około 4% chorych. Materiał i metoda: Przypadek przedstawiono na podstawie dokumentacji medycznej pacjenta. Opis przypadku: Raport opisuje przypadek 73-letniego pacjenta z przewlekłą obturacyjną chorobą płuc i po niedokrwiennym udarze mózgu. Chory był kilkukrotnie leczonego na Oddziale Neurologii z powodu ruchów mimowolnych lewej kończyny górnej, głowy i języka. W tomografii komputerowej głowy w rzucie jąder podstawy stwierdzono obustronnie ogniska naczyniopochodne. U pacjenta wiele razy obserwowano spadek saturacji tlenem poniżej 90%, co znacznie nasilało ruchy mimowolne. Po nasyceniu tlenem ruchy te ustępowały, by pojawić się po jakimś czasie, ale już ze znacznie mniejszą amplitudą. Po udarze niedokrwiennym w prawej okolicy czołowej ruchy mimowolne zanikły samoistnie. Wyniki: Ruchy balistyczno-pląsawicze i dystoniczne są związane z uszkodzeniem jąder podkorowych, najczęściej w przebiegu zmian naczyniopochodnych. U opisywanego pacjenta zmiany naczyniopochodne zostały potwierdzone w badaniu tomograficznym. Wnioski: W przedstawionym przypadku masywne ruchy mimowolne nasilały się przy spadku saturacji tlenem poniżej 90%, co można wiązać z niekorzystnym działaniem hipoksji na obszary niedokrwienne mózgowia. Przyczyną ustąpienia ruchów mimowolnych mogło być powstanie nowego ogniska niedokrwiennego w prawym płacie czołowym i zahamowanie działania pobudzającego jąder podstawy na układ ruchowy.

    Opis:
    By considering a specific scenario of early language evolution, here I advocate taking into account one of the most obvious players in the evolution of human language capacity: (sexual) selection. The proposal is based both on an internal reconstruction using syntactic theory, and on comparative typological evidence, directly bringing together, formal, typological, and evolutionary considerations. As one possible test case, transitivity is decomposed into evolutionary primitives of syntactic structure, revealing a common denominator and the building blocks for crosslinguistic variation in transitivity. The approximations of this early grammar, identified by such a reconstruction, while not identical constructs, are at least as good proxies of the earliest stages of grammar as one can find among tools, cave paintings, or bird song. One subtype of such “living fossils” interacts directly with biological considerations of survival, aggression, and mate choice, while others clearly distinguish themselves in fMRI experiments. The fMRI findings are consistent with the proposal that the pressures to be able to master ever more and more complex syntax were at least partly responsible for driving the selection processes which gradually increased the connectivity of the Broca’s-basal ganglia network, crucial for syntactic processing, among other important functions.
