Objective.-The aim of this study was to determine the lifetime prevalence of vertigo and dizziness in patients with migraine as compared with controls and to establish the lifetime prevalence of migrainous vertigo.Background.-Dizziness and vertigo are relatively frequent complaints in general population; however, the prevalence of migrainous vertigo has not been extensively studied so far.Methods.-The study included 327 migraine patients and 324 controls who do not suffer from frequent headaches. The study and control group were assessed clinically and through diagnostic workup for having vertigo, dizziness, hypotension, and sideropenic anemia.Results.-Vertigo or dizziness was experienced by 51.7% of migraine patients (MVL group) and 31.5% in the control group (CVL group), P < .0001. Among the MVL group, 23.2% of patients met the criteria for migrainous vertigo. There was no difference between the MVL group and CVL group in frequency of attacks or the pattern of symptom appearance in relation to head movement. Patients in the MVL group more frequently had hypotension, P = .011. Patients with migraine with aura significantly more often had migraine attacks in association with vertigo or dizziness, P < .0001.Conclusion.-The lifetime prevalence of migrainous vertigo is relatively frequent in migraine patients, especially in migraine with aura.

: The MoCA successfully identified reduced cognitive status in patients with ICAs/o. The MoCA subtest scores revealed a pattern of cognitive impairment similar to that documented in other studies using more extensive neuropsychological tests. MoCA could be used as part of the clinical evaluation of patients with ICAs/o.

Substantia nigra hyperechogenicity on TCS is a highly specific finding of PD, where in healthy individuals or in ET patients, it might correspond to an increased risk of developing PD later in life or might also be because of the impairment of nearby area of nucleus ruber in ET patients, as suggested by positron emission tomography studies. TCS may serve as a practical and sufficiently sensitive neuroimaging tool in PD diagnoses and in distinguishing it from ET; its repeatability and accuracy might add to its practical value.

The results of this study indicate that respondents showed a fair knowledge about stroke signs and risk factors for stroke. The results of our study will help to create and plan programmes for improvement of public health in Croatia.

Stroke is a one of the leading causes of morbidity and mortality in the world. Carotid atherosclerosis is recognized as an important factor in stroke pathophysiology and represents a key target in stroke prevention; multiple treatment modalities have been developed to battle this disease. Multiple randomized trials have shown the efficacy of carotid endarterectomy in secondary stroke prevention. Carotid stenting, a newer treatment option, presents a less invasive alternative to the surgical intervention on carotid arteries. Advances in medical therapy have also enabled further risk reduction in the overall incidence of stroke. Despite numerous trials and decades of clinical research, the optimal management of symptomatic and asymptomatic carotid disease remains controversial. We will attempt to highlight some of the pivotal trials already completed, discuss the current controversies and complexities in the treatment decision-making, and postulate on what likely lies ahead. This paper will highlight the complexities of decision-making optimal treatment recommendations for patients with symptomatic and asymptomatic carotid stenosis.

The role of cerebral hypoperfusion in the posterior circulation has not been clearly established in migraine. The purpose of this study was to determine the role of vertebral artery (VA) hypoplasia in the pathogenesis of migraine. We studied the extracranial part of VA in 59 migraine patients (17 with and 42 without aura) using color Doppler. In migraine with aura, 29% of patients had hypoplastic VA, and in migraine without aura 7%. In migraine with aura, mean diameter of the right VA was 2.7+/-0.7 mm, and of the left 3.3+/-0.7 mm; in migraine without aura mean diameter was 3.1+/-0.5 mm on the right, and 3.3+/-0.6 on the left. In migraine with aura, mean systolic blood flow velocity was 55+/-16 cm/s on the right, 60+/-17 cm/s on the left, in migraine without aura 57+/-18 cm/s on the right, 57+/-18 cm/s on the left. We observed higher frequency of hypoplastic VA in migraine with aura, suggesting that hypoplasia of VA may be an additional factor which can lead to hypoperfusion in the posterior circulation during the aura phase.

Transcranial sonography (TCS) has never been used in the evaluation of morphology of pineal gland. The aim of the study was to assess the possibility of TCS to distinguish normal from cystic pineal gland and to correlate its size with magnetic resonance imaging (MRI) at the first examination and during follow-up. Sixty patients with previously made MRI of the brain were evaluated by two independent observers using TCS, blinded to the results of the MRI. Inappropriate bone window limited TCS examination in seven patients. All 14 pineal gland cysts (PGC) seen on MRI were detected by both observers using TCS. Control group consisted of 39 healthy examinees. No statistically significant difference has been found between: PGC size measured by first and second observer by TCS (P = 0.425), PGC size measured by TCS and MRI (first observer, P = 0.353; second observer, P = 0.425), size of the pineal gland measured by TCS and MRI in control group (first observer, P = 0.497; second observer, P = 0.370) or interobserver variability in control group (P = 0.373). The MRI and TCS follow-up of ten patients after six months did not show any difference in size of PGC. TCS can be used as a method in detection, measurement and follow-up of PGC.
