ReviewA systematic review of Terson's syndrome: frequency and prognosis after subarachnoid haemorrhage.
To review systematically the frequency and prognostic significance of vitreous haemorrhage in patients with subarachnoid haemorrhage (Terson's syndrome). ⋯ Prospective studies show a higher frequency of Terson's syndrome than retrospective studies, suggesting that vitreous haemorrhage is not well documented. Vitreous haemorrhage is an adverse prognostic finding in patients with subarachnoid haemorrhage.

Cerebral motor control in patients with gliomas around the central sulcus studied with spatially filtered magnetoencephalography.
Application of spatially filtered magnetoencephalography (MEG) to investigate changes in the mechanism of cerebral motor control in patients with tumours around the central sulcus. ⋯ The altered pattern of ERD in the patient group during affected side hand movement suggests recruitment of diverse motor areas, especially the ipsilateral MI/SI, which may be required for the effective movement of the affected hand.

Early pathological changes in the parkinsonian brain demonstrated by diffusion tensor MRI.
To determine whether the fractional anisotropy (FA) of magnetic resonance diffusion tensor imaging is decreased in the nigrostriatal projection in parkinsonian patients. ⋯ Assuming that the loss of FA parallels the neuronal change in the brain, the results are consistent with the view that more than half the dopaminergic neurones in the nigrostriatal projection are lost before the onset of Parkinson's disease. Close comparison of FA in the basal ganglia may contribute to the early diagnosis of Parkinson's disease.
