The aim of this study was to estimate the role of transcranial sonography in detecting basal ganglia changes as structural biomarkers in migraine. Transcranial sonography was performed on Aloka prosound α-10. Semiquantitative and planimetric methods were applied when basal ganglia changes were detected. Comparison between groups was performed by unpaired Student's t test and Spearman's correlation test. We analyzed 30 migraine patients and 30 age-/sex-matched controls. Substantia nigra hyperechogenicity was detected in 36...

Background. This study was conducted to show the prompt effect of chunghyul-dan (CHD) on cerebral hemodynamics in order to provide evidence for its use in stroke prevention. Methods. Hyperventilation-induced CO2 reactivity of the middle cerebral artery was measured in 12 healthy male volunteers (mean age: 26.3 ± 1.1 years) using transcranial Doppler sonography. All subjects were examined before and for 3 hours after administration, with an interval of 1 week between measurements. Results. Compared to baseline, the CO2 reactivity of the middle cerebral artery increased significantly at 2 and 3 hours after the administration of CHD (600 mg and 1200 mg)...

BACKGROUND: There are contradictory reports concerning the validity of transcranial sonography (TCD and TCCS) for examinations of the basilar artery. Here we investigated sensitivity and specificity of transcranial sonography for the detection of basilar artery stenosis and in-stent-restenosis compared to cerebral angiography. METHODS: We analyzed data of 104 examinations of the basilar artery. The association between sonographic peak systolic velocity (PSV) and degree of stenosis obtained by cerebral angiography was evaluated applying Spearman's correlation coefficient...

INTRODUCTION: Subarachnoid hemorrhage (SAH)represents hemorrhage in the space between arachnoidea and pia mater, due to aneurysm burst, spontaneously or as a consequence of trauma. It is condition that occurs more common in women than men, and its most common complications are rebleeding and vazospasm. As a result of vasospasm, develops ischemia in the portion of brain tissue that can cause additional neurological deficit. Transcranial Doppler Sonography (TCD) is a noninvasive ultrasound diagnostic method that allows monitoring of the state of intracerebral hemodynamics...

Differential diagnosis of patients with Chronic Disorders of Consciousness (DoC) is rather challenging, owing to the lack of objective approaches highlighting residual awareness. Sophisticated functional neuroimaging have provided high diagnostic value, but their application in the clinical setting is limited due to their relative complexity, cost, availability and poor collaboration of persons with DoC. By using a specific ultrasound-based methodology, namely Transcranial B-mode Parenchymal Sonography (TCS), it is possible to obtain images of the main parenchymal brain structures...

Transcranial sonography (TCS) shows an increased echogenic area of the substantia nigra (SN) in patients with Parkinson disease (PD). It has been increasingly used in the diagnosis of PD and its differentiation from atypical parkinsonian syndromes. Here, we studied the diagnostic accuracy of SN TCS in Italian patients. In this blinded cross-sectional study (NOBIS study), two expert neuro-sonologists performed TCS in 25 PD patients and 29 age- and sex-matched controls. The study participants were completely hidden to the TCS investigators using large drapery...

BACKGROUND: It is unknown whether contrast transcranial color-coded sonography of vertebral artery monitoring via the foramen magnum window (cTCCS-VA) is useful to detect right-to-left shunt (RLS). We investigated whether cTCCS-VA can be proposed as an alternative to middle cerebral artery monitoring via the temporal bone window (cTCCS-MCA) for RLS detection, as compared with contrast transesophageal echocardiography (cTEE). METHODS: We evaluated 112 patients with ischemic stroke or transient ischemic attack...

BACKGROUND AND PURPOSE: The axial mesencephalic transcranial sonography plane is an established and sensitive diagnostic tool for the differentiation of Parkinson's disease and essential tremor. However, the substantia nigra can also be depicted in a second coronal examination plane, whose diagnostic value has not yet been evaluated. Furthermore, the M-mode tremor frequency determination represents another sonographic tool, which might yield additional diagnostic value. METHODS: We included patients with diagnosed Parkinson's disease (n = 31), essential tremor (n = 16), and healthy age-matched controls (n = 16)...

The recurrent 22q11.2 deletion is a genetic risk factor for early-onset Parkinson's disease. Adults with the associated 22q11.2 deletion syndrome (22q11.2DS) may exhibit phenotypes that could help identify those at highest risk and reveal disease trajectories. We investigated clinical and neuroimaging features relevant to Parkinson's disease in 26 adults: 13 with 22q11.2DS at genetic risk of Parkinson's disease (mean age = 41.5 years, standard deviation = 9.7), 12 healthy age and sex-matched controls, and a 22q11...

Early diagnosis of anxiety and depression may be facilitated by the use of neurobiological markers. In depression and panic disorder, transcranial sonography (TCS) has revealed decreased echogenicity of the brainstem raphe (BR). The aim of the present study was to detect whether decreased echogenicity of the BR correlates with personality features described in the five-dimension model, especially neuroticism. We examined 100 healthy volunteers using quantitative and qualitative TCS, the five-dimension revised NEO Personality Inventory, Beck´s scales of anxiety and depression, and the Social Re-adjustment Rating Scale (SRRS)...

Two centuries ago in 1817, James Parkinson provided the first medical description of Parkinson's disease, later refined by Jean-Martin Charcot in the mid-to-late 19th century to include the atypical parkinsonian variants (also termed, Parkinson-plus syndromes). Today, Parkinson's disease represents the second most common neurodegenerative disorder with an estimated global prevalence of over 10 million. Conversely, atypical parkinsonian syndromes encompass a group of relatively heterogeneous disorders that may share some clinical features with Parkinson's disease, but are uncommon distinct clinicopathological diseases...

INTRODUCTION: Although the nature of basal ganglia hyperechogenicity in transcranial sonography (TCS) examinations remains unclear, many studies have shown associations between hyperechogenicity and iron accumulation. The role of iron in basal ganglia hyperechogenicity raises interest in the use of TCS in forms of neurodegeneration with brain iron accumulation (NBIA). Here we analyzed TCS and magnetic resonance imaging (MRI) findings among patients affected by one type of NBIA, mitochondrial membrane protein-associated neurodegeneration (MPAN)...
