Delirium may be a presenting feature in acute subarachnoid haemorrhage (SAH). The aim of this study was to investigate the risk factors for delirium in acute SAH and to analyse the relation between delirium and location and amount of haematic densities and hydrocephalus. ⋯ Delirium was detected in 16% of acute SAH patients. Intraventricular bleeding, hydrocephalus and basofrontal haematomas contribute to the pathogenesis of delirium, through damage to anatomical networks subserving sustained attention, declarative memory and the expression of emotional behaviour.

Cerebral infarction (CI) is a serious complication of tuberculous meningitis (TBM). It can be asymptomatic or symptomatic, causing stroke. We studied 40 TBM patients. ⋯ Patients with LAI might develop posterior circulation CI more frequently than those with LI only. CI is a common complication of TBM locally, with LAI and multiple CI being common. Two thirds of TBM patients complicated by CI had poor prognosis despite adjunctive dexamethasone treatment.

Randomized Controlled Trial Clinical TrialEnhanced antiplatelet effects of clopidogrel plus acetylsalicylic acid compared with acetylsalicylic acid alone or combined with extended-release dipyridamole in healthy volunteers.
Previous studies have shown the potential benefit of using antiplatelet agents with complementary modes of action. ⋯ Based on ex vivo platelet aggregometry, clopidogrel + ASA is a more potent antiplatelet regimen than either ASA alone or the marketed combination of dipyridamole + ASA. However, the clinical significance of this finding remains to be confirmed.

Multicenter StudyCan telemedicine contribute to fulfill WHO Helsingborg Declaration of specialized stroke care?
Providing stroke unit treatment for all stroke patients is a cross-national goal as stated in the WHO Helsingborg Declaration. In order to achieve specialized stroke care for a large area, two stroke centers and 12 community hospitals established an integrative stroke network. This evaluation was performed to analyze achieved advances in stroke management. ⋯ This stroke network concept leads to a substantial improvement of stroke management. Telemedicine contributes to an early etiological assessment and fills the gap of specialized stroke expertise in neurologically underserved areas.

Clinical TrialSuperficial temporal artery duplex ultrasonography for improved cerebral hemodynamics after extracranial-intracranial bypass surgery.
To investigate the utility of superficial temporal artery (STA) duplex ultrasonography (STDU) for evaluating the improvement of the cerebral hemodynamics after extracranial-intracranial (EC-IC) bypass. ⋯ STDU was available for evaluating postsurgical patency of the bypass flow and the rCBF of the ipsilateral MCA territory. The mean blood flow velocity of the operated STA is a highly sensitive parameter for predicting rCBF in the ipsilateral MCA territory after EC-IC bypass.
