Rabies encephalitis is a uniformly fatal disease with several hypothesis proposed to explain pathogenesis and mortality. One such theory premises deficiency of neuronal nitric oxide synthetase deficiency causing selective cerebral vasospasm. We present transcranial Doppler findings in a case of rabies that did not show imaging evidence of vasospasm. Transcranial Doppler in two published cases h...

Recent advances of transcranial magnetic stimulation can provide new methods to elucidate the mechanism of higher brain function or cortical plasticity. For example, transcranial magnetic stimulation can produce transient disruption of the visual perception or modulation of cortical functions. Probably, the induced eddy current in the brain disturbs the information processing from external sign...

We studied whether five sessions of 10 Hz repetitive transcranial magnetic stimulation (rTMS treatment) applied over the dorsolateral prefrontal cortex (DLPFC) or the primary motor cortex (MC) in advanced Parkinson's disease (PD) patients would have any effect on L-dopa-induced dyskinesias and cortical excitability. We aimed at a randomised, controlled study. Single-pulse transcranial magnetic ...

BACKGROUND AND PURPOSE Large vessels are also affected in sickle cell disease. The aim of this study was to assess several parameters in adult patients with sickle cell disease compared with control subjects and in patients with sickle cell disease with stroke. METHODS Carotid arterial stiffness, intima-media thickness, and transcranial Doppler ultrasonography were measured. RESULTS Arteria...

Transcranial Doppler sonography is a non-invasive, non-ionising, inexpensive, portable and safe technique that uses a pulsed Doppler transducer for assessment of intracerebral blood flow. This article deals with the principles and technique of transcranial Doppler sonography. It gives a brief overview of its use in evaluation of intracranial steno-occlusive disease, subarachnoid haemorrhage, an...

Objectives: Stroke is the leading cause of long-term disability. Hand motor impairment resulting from chronic stroke may have extensive physical, psychological, financial, and social implications despite available rehabilitative treatments. The best time to start treatment for stroke, is in sub-acute period. Repetitive transcranial magnetic stimulation (rTMS) is a method of stimulating and ...

Abstract Background The additional information that transcranial Doppler can provide as part of a multimodal imaging protocol in many clinical settings has not been evaluated. Main body Transcranial is bedside procedure used to assess cerebral blood flow velocity via circulation and pulsatility index (PI). Many diseases lead vessels vasospasm subarachnoid hemorrhage trauma. Cerebral represented...

PURPOSE OF REVIEW To discuss recent strategies for boosting the efficacy of noninvasive transcranial brain stimulation to improve human brain function. RECENT FINDINGS Recent research exposed substantial intra- and inter-individual variability in response to plasticity-inducing transcranial brain stimulation. Trait-related and state-related determinants contribute to this variability, challen...
