Plasma neurofilament light outperforms glial fibrillary acidic protein in differentiating behavioural variant frontotemporal dementia from primary psychiatric disorders.

Objective: Timely, accurate distinction between behavioural variant frontotemporal dementia (bvFTD) and primary psychiatric disorders (PPD) is a clinical challenge. Blood biomarkers such as neurofilament light chain (NfL) and glial fibrillary acidic protein (GFAP) have shown promise. Prior work has shown NfL helps distinguish FTD from PPD.

Sustainability of an intervention to reduce waiting for access to an epilepsy outpatient clinic.

Purpose: Delays in outpatient specialist neurologist care for people with epilepsy are common despite recommendations for prompt access. There is evidence to suggest that there are interventions that can minimise waitlists and waiting time. However, little is known about whether such interventions can result in sustained improvements in waiting.

Plasma neurofilament light in behavioural variant frontotemporal dementia compared to mood and psychotic disorders.

Objective: Blood biomarkers of neuronal injury such as neurofilament light (NfL) show promise to improve diagnosis of neurodegenerative disorders and distinguish neurodegenerative from primary psychiatric disorders (PPD). This study investigated the diagnostic utility of plasma NfL to differentiate behavioural variant frontotemporal dementia (bvFTD, a neurodegenerative disorder commonly misdiagnosed initially as PPD), from PPD, and performance of large normative/reference data sets and models.

Methods: Plasma NfL was analysed in major depressive disorder (MDD, = 42), bipolar affective disorder (BPAD, = 121), treatment-resistant schizophrenia (TRS, = 82), bvFTD ( = 22), and compared to the reference cohort (Control Group 2, = 1926, using GAMLSS modelling), and age-matched controls (Control Group 1, = 96, using general linear models).

Treatment Outcomes of Newly Diagnosed Epilepsy: A Systematic Review and Meta-analysis.

Background And Objectives: Understanding the multi-faceted treatment outcomes of newly diagnosed epilepsy is critical for developing rational therapeutic strategies. A meta-analysis was conducted to derive pooled estimates of a range of seizure outcomes in children and adults with newly diagnosed epilepsy commenced on antiseizure medication treatment, and to identify factors associated with different outcomes.

Methods: PubMed/EMBASE were screened for eligible articles between 1 January, 1995 and 1 May, 2021 to include unselected cohort studies with a ≥ 12-month follow-up of seizure outcomes.

Meta-Analysis of the Use of Head Impulse Test and Head Impulse Test with Direction Changing Nystagmus and Test of Skew Deviation in the Diagnosis of Peripheral Vertigo and Stroke.

Introduction: The head impulse test (HIT) and HIT combined with direction-changing Nystagmus-Test of Skew deviation (HINTS) have been proposed as bedside tests to differentiate between peripheral and central causes of vertigo in the emergency department (ED). We conducted a meta-analysis of the HIT and HINTS tests to diagnose peripheral vertigo (PV) and central vertigo.

Methods: Pubmed, Google Scholar, EmBase, and articles references published in English up to July 2021 were searched for keywords "vertigo" or "acute vestibular syndrome" or "dizziness" and "head impulse" and "stroke.

Plasma Neurofilament Light Chain and Clinical Diagnosis in Frontotemporal Dementia Syndromes.

Background: Frontotemporal dementia (FTD) syndromes, mimics, phenocopy (phFTD), and slowly progressive behavioral variant FTD (bvFTD) can be difficult to distinguish clinically. Biomarkers such as neurofilament light chain (NfL) may be helpful.

Objective: To study plasma NfL levels in people with FTD syndromes and determine if plasma NfL can distinguish between FTD syndromes and phFTD.

Cerebral Large Vessel Occlusion Caused by Fat Embolism-A Case Series and Review of the Literature.

The diagnosis of fat embolism syndrome typically involves neurological, respiratory and dermatological manifestations of microvascular occlusion 24-72 h after a precipitating event. However, fat embolism causing cerebral large vessel occlusion strokes and their sequelae have rarely been reported in the literature. This case series reports three patients with fat emboli post operatively causing cerebral large vessel occlusions, as well as a review of the literature to identify differences in clinical presentations and outcomes in stroke secondary to fat emboli causing large vessel occlusions compared to those with fat embolism syndrome.

The prevalence of epileptic seizures in multiple sclerosis in a large tertiary hospital in Australia.

Rationale: To determine the prevalence of epileptic seizures in multiple sclerosis (MS) at an Australian tertiary hospital and to define their clinical features.

Methods: We retrospectively analysed adult patients at the Royal Melbourne Hospital electronically identified to have ICD codes for MS and seizures and/or epilepsy between 1996 to 2019, utilising paper and electronic-based records.

Results: Of the 2,125 MS patients identified, 16 (0.

Surgical considerations in a paediatric case of a large skull-base epithelioid haemangioendothelioma.

Intracranial epithelioid haemangioendothelioma (EHE) is a rare intermediate grade vascular tumour with heterogeneous clinical and histopathological behaviour. We present the surgical considerations of an exceptionally large skull-based EHE in an 11-year old female who presented to our institution with headaches and a protuberance over the left parietal area. Magnetic resonance imaging (MRI) demonstrated a left sided 10.
