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)
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)
Stroke is the leading cause of disability in modern society. In developed countries stroke is the second or the third cause of death, and in Croatia it is the leading cause of death. Therefore, stroke is not only a great medical, but also economic burden. Figures show that the incidence of stroke in transitional countries is increasing, so the epidemic of(More)
Despite the enormous progress done in the course of last years in diagnosis, treatment and rehabilitation of stroke patients, prevention is still main strategy in approaching the stroke. After the comprehensive review of the organization of stroke care, treatment and neurorehabilitation of stroke patients, this part shows the recommendations of the Croatian(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)
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)

BACKGROUND AND AIM Changes of arterial stiffness indicate alteration in arterial mechanics predisposing to the evolution of stroke or vascular dementia. The aim of this pilot study was to investigate whether ultrasound parameters, particularly beta stiffness index (BSI), should be further explored as independent markers or risk factors for dementia.
