BACKGROUND In Central/Eastern European countries, cerebrovascular diseases are among the leading causes of mortality. We aimed to determine the incidence of first-ever stroke (FES) in the north-western part of Croatia. METHODS A population-based prospective incidence study was conducted between July 1, 2007, and June 30, 2009. Cases were sought from(More)
Changes of mean blood flow velocities (MBFV) in the posterior cerebral arteries (PCA) recorded during visual stimulation in a group of 51 healthy, right-handed volunteers are presented. There were 27 (52.9%) males and 24 (47.1%) females, aged 20-59 years (mean age: 36.98 years). Measurements were performed with a hand-held 2 MHz transcranial Doppler (TCD)(More)
Essential tremor is one of the most common movement disorders characterized by combination of postural bilateral action tremor with frequency 4-12MHz. Diagnosis is based on clinical examination, while neuroimaging methods so far have limited role. Recent reports showed that substantia nigra (SN) hyperechogenicity detected by transcranial sonography (TCS) is(More)
We investigated the brainstem blink reflex in patients suffering from idiopathic and symptomatic trigeminal neuralgia to establish possible dysfunction in the reflex cycle and determine eventual differences between the two disease types. The study included 35 patients with idiopathic disease and seven patients with symptomatic disease, their results(More)
There is emerging evidence that lipids play an important role in many neurodegenerative processes, for example in Alzheimer's disease (AD). Although different lipid alterations in the AD brain have been reported, there have only been very few investigations of lipid changes in the cerebrospinal fluid (CSF). Recent developments in mass spectrometry (MS) have(More)
OBJECTIVES Until today there is no reliable test that can clearly distinguish Parkinson's disease (PD) from the essential tremor (ET). Our aim was to determine the usefulness of the transcranial sonography (TCS) in the differential diagnosis of the PD and ET as well as the interobserver reliability for this method. METHODS Transcranial sonography of(More)
These are evidence based guidelines for the management of patients with carotid stenosis, developed and endorsed by Croatian Society of Neurovascular Disorders, Croatian Society of Neurology, Croatian Society of Ultrasound in Medicine and Biology, Croatian Society for Radiology, Croatian Society of Vascular Surgery and Croatian Society of Neurosurgery. They(More)
Recent transcranial sonography (TCS) studies showed that disruption of echogenic midbrain line, corresponding to basal limbic system and raphe nuclei (RN) within, might represent functional marker for the development of depression. Major depressive disorder (MDD) is one of the most common psychiatric disorders associated with suicidal ideation. We initiated(More)
There are no reliable data on the relationship between ischemic stroke and elevated triglyceride levels. Results of previous studies have shown that elevated total cholesterol, high low-density lipoprotein cholesterol (LDL-C) and low high-density lipoprotein cholesterol (HDL-C) are modifiable risk factors for ischemic stroke. Recent evidence suggests that(More)
