Huge steps forward in understanding and treatment of ischemic stroke happened in the last several decades. Significant part of this progress is due to advances in diagnostic possibilities, with the leading role of transcranial Doppler (TCD). The American Academy of Neurology has recently published new guidelines and indications for TCD use. Indications with the highest rank, when TCD is able to provide information with established clinical utility, are designated as follows: (1) screening of children aged 2 to 16 years with sickle cell disease for assessing the stroke risk, and (2) detection and monitoring of vasospasm in spontaneous subarachnoid hemorrhage. TCD indications in setting where this examination provides important information but with still indefinite clinical utility are: (1) intracranial steno-occlusive disease, with data insufficient to recommend replacement of conventional angiography with TCD, despite obvious TCD usefulness and precision, and (2) cerebral circulatory arrest detection, as confirmatory test in support of clinical diagnosis of brain death. The major limiting factor of TCD application is dependence on an examiner's training and skills. Only strict application of diagnostic protocols and accepted criteria, with knowledge of pathophysiologic basis of cerebrovascular diseases and TCD principles, can result in conclusive findings. TCD is the source of valuable information for neurologists and other specialty physicians. This text presents review of other TCD indications and their application in everyday practice.

Five-year survival rate in VaD is 39%, while it is estimated to be 75% in healthy persons of the same age. It is therefore important to make correct diagnosis of VaD early in the course of the disease. Risk factors forVaD are identical to stroke risk factors, and there are significant possibilities for the prevention of vascular cognitive decline. Cognitive decline develops acutely or step-by-step within three months after stroke, but more gradual progression of intellectual decline is also possible. Neurological examination can reveal pyramidal and extrapyramidal signs, pseudobulbar palsy, gait disturbance and urinary incontinence. Neuropsychological profile comprises the loss of cognitive set shifting, decline in word fluency, verbal learning difficulties, perseverations, difficulties in complex figure copying, and in patients with cortically located lesions also problems with speech and praxia. The basis of the diagnosis is, besides history, neurological examination and neuropsychological assessment, computed tomography and/ or magnetic resonance brain imaging. Vascular risk factors control is the most important measure in VaD prevention. Modern guidelines for the treatment of cognitive decline in VaD emphasize that donepezil can be useful in the improvement of cognitive status at the level of Class Ila recommendation at the level of evidence A, while memantine may be useful in patients with mixed VaD and Alzheimer's disease dementia.

    New therapeutic strategies under development aim to improve recanalization rates and clinical outcomes after ischemic stroke. One such approach is ultrasound (US)-enhanced thrombolysis, or sonothrombolysis, which can improve thrombolytic drug actions and even intrinsic fibrinolysis. Although the mechanisms are not fully understood, it is postulated that thrombolysis enhancement is related to... [Show full abstract]

      Transient ischemic attack (TIA) is a warning sign of stroke, and stroke is one of the leading causes of morbidity and mortality in the world. The assessment and management of TIAs can be difficult even for an experienced neurologist. The propose of this article is to increase the awareness and establish a diagnostic and therapeutic approach to patients with TIA. In terms of therapy, patients... [Show full abstract]

        Transcranial Doppler (TCD) is the only diagnostic tool that can provide continuous information about cerebral hemodynamics in real time and over extended periods. In the previous paper (Part 1), we have already presented the basic ultrasound physics pertaining to TCD, insonation methods, and various flow patterns. This article describes various advanced applications of TCD such as detection of... [Show full abstract]

          Background/Aim. The association between the right-to left shunt (RLS) and migraine with aura (MA) has been proven so far. The aim of this study was to determine if the presence of RLS detected as a result of transcranial doppler (TCD) bubble-test, makes any difference in clinical presentation, aura and headache in patients with MA. Methods. A single-group descriptive study was conducted on 153... [Show full abstract]

            Transcranial Doppler (TCD) is the only noninvasive modality for the assessment of real-time cerebral blood flow. It complements various anatomic imaging modalities by providing physiological-flow related information. It is relatively cheap, easily available, and can be performed at the bedside. It has been suggested as an essential component of a comprehensive stroke centre. In addition to its... [Show full abstract]
