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)
Visual stimulation influences mean blood flow velocities (MBFV) in posterior cerebral arteries (PCA). In 51 healthy, right-handed volunteers MBFV were measured in PCA with opened and closed eyes and while watching colored light (red, yellow, green, blue) for 1 minute. Volunteers had eyes closed 2 minutes between different colors. MBFV in left PCA was 41.2(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)

We have recently reported that transcranial sonography (TCS) is a method competitive to magnetic resonance neuroimaging (MRI) in the evaluation of pineal gland lesions. The aim of the present is study was to assess the usefulness of TCS in a larger patient sample during a two-year follow up. Twenty patients with incidental pineal gland cyst (PGC) detected(More)
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)
SUMMARY – While nigral substance (NS) is either barely detectable or undetectable in healthy individuals, the majority of patients with Parkinson’s disease (PD) display its increased echogenicity on transcranial sonography (TCS). The aim of the study was to assess the possibility of TCS to differentiate PD from other movement disorders by the measurement of(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)
SUMMARY – Secondary preventive measures such as measuring serum cholesterol levels and treatment of hypercholesterolemia with statins, 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibi-tors, are insufficiently used in patients with acute stroke or transient ischemic attack, although statins offer potential benefits for reducing the incidence(More)
