This review makes the case that idiopathic normal pressure hydrocephalus (iNPH) is an outdated term because new information indicates that the syndrome is less idiopathic and that the cerebrospinal fluid (CSF) pressure of normal individuals is affected by several factors such as body mass index, age, and sex. Our review updates the epidemiology of iNPH and provides a clinical approach to the management of these patients. All the clinical features of iNPH are common in older individuals, and each has many causes, so the diagnosis is difficult. The first step in reaching an accurate diagnosis is to address the possible contributory factors to the gait abnormality and determine what if any role iNPH may be playing. The two best diagnostic tests are neuroimaging and cerebrospinal fluid (CSF) diversion (large volume lumbar puncture or external lumbar drainage) with pre/post gait evaluation. This review provides an update on the growing evidence that vascular disease, impaired CSF absorption, congenital, and genetic factors all contribute to the pathogenesis of iNPH. We suggest replacing the term iNPH with the term Hakim syndrome (HS) in acknowledgement of the first person to describe this syndrome. Lastly, we discuss the improvements in shunt technology and surgical techniques that have decreased the risks and long-term complications of shunt surgery.

Introduction: Unilateral gamma knife thalamotomy (GKT) is a treatment option for pharmacoresistant tremor of various aetiologies. There have been to date no randomised controlled trials performed to assess its safety and efficacy. Our aim was to summarise a two-year multimodal observation of patients with tremor caused by Parkinson's Disease (PD) or essential tremor (ET).

Material and methods: 23 patients with PD (n = 12) or ET (n = 11) were included. They underwent assessments before, V0 (n = 23), and 12 months, V12 (n = 23), and 24 months, V24 (n = 15), after unilateral GKT. Patients were assessed with psychological tests and acoustic voice analysis. Tremor assessment was performed with a digitising table using the Fahn-Tolosa-Marin rating scale (FTMRS). The Unified Parkinson's Disease rating scale part III (UPDRS-III) was also used in the PD group. Gait and balance was assessed using clinical tests, stabilometric platform, and treadmill.

Results: No side effects were observed in a two-year follow-up. There was no notable deterioration observed in the patients' psychological evaluation, speech, or assessment of gait and balance. The scores were significantly lower (p = 0.01) in parts A and B of FTMRS one year after GKT. In post hoc analysis, the scores did not differ significantly between V0 and V24. In FTMRS part C (activities of daily living), no significant change was observed. There was no significant difference in total UPDRS part III score or in score of UPDRS part III domains 3 and 4 ('tremor at rest' and 'action and postural tremor of hands') between measurements.

Conclusions: UGKT may be a safe treatment modality if performed in an experienced centre. Tremor reduction may diminish over time, and UGKT did not lead to cognitive, gait or speech deterioration in a long-term observation.

Aim of study: We sought to compare MANAGE-PD and 5-2-1 Delphi criteria which are two commonly used and approved screening tools in Parkinson's Disease, in order to highlight their strengths and limitations.

Clinical rationale for study: Timely intervention with device-aided therapies is vital as it enables improving motor symptoms, lowering the dosage and side-effects of dopaminergic treatment, and improving patients' and caregivers' quality of life. Various screening tools have been created to help clinicians find the best candidates for device-aided therapies (DAT) for advanced Parkinson's Disease. In this study, we aimed to compare the 5-2-1 Delphi criteria to MANAGE-PD to determine how they could be used specifically to maximise their potential.

Material and methods: All of the patients (260) included in this study were DAT-naive, > 18 years of age, diagnosed with Parkinson's Disease, and had been referred to the Department of Neurology for qualification for advanced therapies over a 4-year period (2019-2022). They were subjected to both 5-2-1 Delphi criteria and MANAGE-PD tools and divided into subgroups based on the results of the screening. The data of patients was then statistically analysed.

Results: In the study group, 51 patients (19.5%) met all three of the 5-2-1 criteria, and 123 (47.1%) patients were categorised as '3' in MANAGE-PD, meaning that they may benefit from DAT. Finally, at the local centre level, 64 (24.5%) patients were qualified for DAT. 22 (34.4%) patients who were qualified for DAT by a clinician did not meet the 5-2-1 criteria.

Conclusions: The 5-2-1 scheme based on the data from this study was characterised by a 92.5% specificity level and 65.1% sensitivity level compared to 69.5% specificity and 98.4% sensitivity level of MANAGE-PD.

Clinical implications: We found that MANAGE-PD has a better screening potential of DAT admission than 5-2-1 criteria. While both tools are reliable and valuable in daily practice, our study suggests that some patients may be omitted when using only less complicated tools such as 5-2-1 during the assessment.

Introduction: Maintaining optimal systemic circulatory parameters is essential to ensure adequate cerebral perfusion (CPP) during neurosurgery, especially when autoregulation is impaired.

Aim of study: To compare two types of total intravenous anaesthesia i.e. target controlled infusion (TCI) and manually controlled infusion (MCI) with propofol and remifentanil in terms of their control of cardiovascular parameters during neurosurgical resection of intracranial pathology.

Material and methods: Patients with supratentorial intracranial pathology were selected for the study. Patients in ASA grades III and IV and those with diseases of the circulatory system were excluded. Patients were randomly divided into two equal groups according to the method of general anaesthesia used i.e. TCI or MCI. During the neurosurgery, the values of mean arterial pressure (MAP), heart rate (HR), bispectral index (BIS) and central venous pressure were monitored and recorded at the designated 14 relevant (i.e. critical from the anaesthetist's and neurosurgeon's points of view) measurement points.

Results: Fifty patients (25 TCI and 25 MCI) were enrolled in the study. The groups did not differ with respect to sex, age and BMI, operation time or volume of removed lesions. TCI-anaesthetised patients had better MAP stability at the respective time points.

Conclusions: Due to the greater stability of MAP, which has a direct effect on CPP, TCI appears to be the method of choice in anaesthesia for intracranial surgery.

Aim of study: The Gastrointestinal Dysfunction Scale for Parkinson's Disease (GIDS-PD) is a novel, disease-specific self-report questionnaire used to quantitatively assess features of gastrointestinal dysfunction symptoms in patients with Parkinson's Disease. The aim of this paper was to validate the Polish translation of the scale, to summarise its consistency with the English language version, and to assess its clinimetric properties.

Clinical rationale for study: Gastrointestinal dysfunction is a common and often debilitating manifestation of Parkinson's Disease (PD). Gastrointestinal symptoms are also considered to be prodromal features of this disease. To date, there has been no scale in Polish that has precisely assessed gastrointestinal symptoms in patients with PD.

Material and methods: The GIDS-PD was translated into Polish by two investigators (M.K. and J.N.). A back-translation was completed by two separate investigators (M.F. and A.A.) who were not involved in the original translation. Afterwards, 10 Polish PD patients underwent cognitive pre-testing. After the final translation was officially approved by the Movement Disorder Society, it was tested on 64 individuals with PD during field testing. For the purpose of testing scale reliability, 20 of the patients recruited for field testing underwent the GIDS-PD for a second time after 8-12 weeks.

Results: The GIDS-PD demonstrated overall good consistency (Cronbach's alpha of 0.74, ICC of 0.74). Regarding the individual domains, the constipation subscore demonstrated good reliability, the bowel irritability subscore demonstrated moderate reliability, and the upper GI subscore demonstrated poor reliability. Upper GI symptoms seem to be less pronounced, and also more varied, in the Polish PD population than in its English language counterpart.

Conclusions and clinical implications: This paper provides a validated Polish translation of the GIDS-PD questionnaire. We highly recommend using the GIDS-PD for research purposes, as well as everyday clinical practice in the Polish PD population.

Introduction: Primary familial brain calcification (PFBC) is a neurodegenerative disease characterised by bilateral calcification in the brain, especially in the basal ganglia, leading to neurological and neuropsychiatric manifestations. White matter hyperintensities (WMH) have been described in patients with PFBC and pathogenic variants in the gene for platelet-derived growth factor beta polypeptide (PDGFB), suggesting a manifest cerebrovascular process. We present below the cases of two PFBC families with PDGFB variants and stroke or transient ischaemic attack (TIA) episodes. We examine the possible correlation between PFBC and vascular events as stroke/TIA, and evaluate whether signs for vascular disease in this condition are systemic or limited to the cerebral vessels.

Material and methods: Two Swedish families with novel truncating PDGFB variants, p.Gln140* and p.Arg191*, are described clinically and radiologically. Subcutaneous capillary vessels in affected and unaffected family members were examined by light and electron microscopy.

Results: All mutation carriers showed WMH and bilateral brain calcifications. The clinical presentations differed, with movement disorder symptoms dominating in family A, and psychiatric symptoms in family B. However, affected members of both families had stroke, TIA, and/or asymptomatic intracerebral ischaemic lesions. Only one of the patients had classical vascular risk factors. Skin microvasculature was normal.

Conclusions: Patients with these PDGFB variants develop microvascular changes in the brain, but not the skin. PDGFB-related small vessel disease can manifest radiologically as cerebral haemorrhage or ischaemia, and may explain TIA or stroke in patients without other vascular risk factors.

Aim of the study: Neuronal pentraxin-2 (NPTX2) is a synaptic protein responsible for modulating plasticity at excitatory synapses. While the role of NPTX2 as a novel synaptic biomarker in cognitive disorders has been elucidated recently, its role in idiopathic normal pressure hydrocephalus (iNPH) is not yet understood.

Clinical rationale for study: To determine if NPTX2 predicts cognition in patients with iNPH, and whether it could serve as a predictive marker for shunt outcomes.

Material and methods: 354 iNPH patients underwent cerebrospinal fluid drainage (CSF) as part of the tap test or extended lumbar drainage. Demographic and clinical measures including age, Evans Index (EI), Montreal Cognitive Assessment (MoCA) score, Functional Activities Questionnaire (FAQ) score, and baseline and post-shunt surgery Timed Up and Go (TUG) test scores were ascertained. CSF NPTX2 concentrations were measured using an ELISA. CSF β-amyloid 1-40 (Aβ1-40), β-amyloid 1-42 (Aβ1-42), and phosphorylated tau-181 (pTau-181) were measured by chemiluminescent assays. Spearman's correlation was used to determine the correlation between CSF NPTX2 concentrations and age, EI, MoCA and FAQ, TUG, Aβ1-40/Aβ1-42 ratio, and pTau-181 concentrations. Logistic regression was used to determine if CSF NPTX2 values were a predictor of short-term improvement post-CSF drainage or long-term improvement post-shunt surgery.

Results: There were 225 males and 129 females with a mean age of 77.7 years (± 7.06). Average CSF NPTX2 level in all iNPH patients was 559.97 pg/mL (± 432.87). CSF NPTX2 level in those selected for shunt surgery was 505.61 pg/mL (± 322.38). NPTX2 showed modest correlations with pTau-181 (r = 0.44, p < 0.001) with a trend for Aβ42/Aβ40 ratio (r = -0.1, p = 0.053). NPTX2 concentrations did not correlate with age (r = -0.012, p = 0.83) or MoCA score (r = 0.001, p = 0.87), but correlated negatively with FAQ (r = -0.15, p = 0.019).

Conclusions: While CSF NPTX2 values correlate with neurodegeneration, they do not correlate with cognitive or functional measures in iNPH. CSF NPTX2 cannot serve as a predictor of either short-term or long-term improvement after CSF drainage.

Clinical implications: These results suggest that synaptic degeneration is not a core feature of iNPH pathophysiology.

Introduction: Spontaneous CSF leak is a known complication of idiopathic intracranial hypertension (IIH). Patients with CSF rhinorrhea present a unique challenge within the IIH population, as the occurrence of a leak can mask the typical IIH symptoms and signs, complicating the diagnosis. Treatment of leaks in this population can also be challenging, with the risk of rhinorrhea recurrence if intracranial hypertension is not adequately treated.

Objective: The aim of this narrative review was to examine current literature on the association between spontaneous CSF rhinorrhea leaks and IIH, focusing on key clinical features, diagnostic approaches, management strategies, and outcomes.

Material and methods: A literature search was executed using the PubMed and Scopus databases. The search was confined to articles published between January 1985 and August 2023; extracted data was then analysed to form the foundation of the narrative review.

Results: This search yielded 26 articles, comprising 943 patients. Average age was 46.8 ± 6.5 years, and average body mass index was 35.8 ± 4.8. Most of the patients were female (74.33%). Presenting symptoms were rhinorrhea, headaches and meningitis. The most common imaging findings were empty sella and encephalocele. The standard treatment approach was endoscopic endonasal approach for correction of CSF rhinorrhea leak, and shunt placement was also performed in 128 (13%) patients. Recurrences were observed in 10% of cases.

Conclusions: The complex relationship between spontaneous CSF leaks and IIH is a challenge that benefits from multidisciplinary evaluation and management for successful treatment. Treatments such as endoscopic repair, acetazolamide, and VP/ /LP shunts reduce complications and recurrence. Personalised plans addressing elevated intracranial pressure are crucial for successful outcomes.

Introduction: The phenomenon known as periodic limb movements in sleep (PLMS) has been linked to a change in autonomic nervous system (ANS) activity and its effect on circulatory regulation. Autonomic dysfunction or dysregulation in patients with PLMS has been described in some domains; however, any relationship between heart rate variability (HRV) and PLMS has not been clearly established. HRV analysis is a recognised, non-invasive research method that describes the influence of the ANS on heart rate (HR). The aim of our study was to further investigate the dysregulation of autonomic HR control in patients with PLMS.

Material and methods: We undertook a retrospective analysis of the polysomnographic (PSG), demographic and medical data of five patients with a total number of 1,348 PLMS. We analysed HR, HRV HF, systolic blood pressure (SBP), and diastolic blood pressure (DBP) for 10 heartbeats before the series of PLMS and 10 consecutive heartbeats as beat-to-beat measurements. The presented method of using successive, short, 10 RR interval segments refers to the time-frequency measurement, which is very clear and useful for presenting changes in the calculated parameters over time and thereby illustrating their dynamics. This method allowed us to assess dynamic changes in HRV HF during successive PLMS series. Statistical analysis was performed using IBM SPSS Statistics (v. 28.0.0.0). The Kruskal-Wallis test was performed to find statistically significant changes from baseline.

Results: No statistically significant changes in HR, SBP, or DBP were found in our group, although an increase in the value of the HRV HF was noted, suggesting an increase in intracardiac parasympathetic activity during the subsequent series of PLMS.

Conclusions: Our study indicates an increase in parasympathetic activity during the appearance of successive PLMS, which, with the simultaneous lack of changes in HR, may suggest an increase in sympathetic activity, and therefore the appearance of so-called 'autonomic co-activation' resulting in the possibility of life-threatening cardiac events.

Clinical implications: Our findings add to the literature information regarding HRV in PLMS, and highlight the need for further studies to elucidate the effects of these conditions on the ANS, and on cardiovascular health.
