Domain-specific trends in cognitive impairment after acute ischaemic stroke.
2012
Little is known about the pattern of subacute cognitive domain impairments after ischaemic stroke, nor the temporal evolution of such impairments. Our objective was to investigate the pattern of cognitive impairment in different neuropsychological domains up to a year after ischaemic stroke. We included prospectively collected data from an observational database of stroke patients at the National Hospital for Neurology and Neurosurgery, Queen Square, London, UK. Patients were categorised into temporal groups according to the time between the index stroke and neuropsychological profiling. The prevalence of impairment in different cognitive domains was then compared between these categories. …
MRI-visible perivascular spaces: relationship to cognition and small vessel disease MRI markers in ischaemic stroke and TIA.
2013
Background MRI-visible perivascular spaces (PVS) are potential neuroimaging markers of cerebral small vessel disease, but their functional significance and mechanisms remain uncertain. We investigated the association between PVS and cognitive impairment, and other MRI markers of small vessel disease, in a patient cohort of ischaemic stroke/transient ischaemic attack (TIA) referrals. Methods Data were collected from a prospective observational database. Standardised detailed neuropsychological testing was performed. A validated visual rating scale on T-2-weighted MRI was used to categorise PVS severity; validated scales were used to assess white matter hyperintensities (WMH), cerebral microb…
