OBJECTIVE Identification of patients with aneurysmal subarachnoid haemorrhage (aSAH) with cognitive impairment is important for patient management (medical treatment, cognitive rehabilitation and social arrangements). The Montreal cognitive assessment (MoCA) is currently recommended over the mini-mental state examination (MMSE) by the U.S. National(More)
BACKGROUND AND PURPOSE After aneurysmal subarachnoid hemorrhage (aSAH), cognitive impairment, even mild and relatively isolated, can be devastating, especially in working-age persons. The Montreal Cognitive Assessment (MoCA) is accepted as a valid screening tool for mild cognitive impairment due to cerebral ischaemia. Whether MoCA is independently(More)
Recent clinical research into aneurysmal subarachnoid hemorrhage (aSAH) has confirmed the long-term effect of cognitive dysfunction on functional outcomes. We hypothesized that early cognitive impairment was a marker of permanent brain injury and hence predicted long-term functional outcome. Hong Kong Chinese patients with aneurysmal subarachnoid hemorrhage(More)
OBJECTIVE Cognitive deficits are common after aneurysmal subarachnoid haemorrhage (aSAH), and clinical evaluation is important for their management. Our hypothesis was that the Montreal Cognitive Assessment (MoCa) is superior to the Mini-Mental State Examination (MMSE) in screening for cognitive domain deficit in aSAH patients. METHODS We carried out a(More)
Dear editor, We recently reported the clinical outcome of traumatic acute subdural hematoma in Hong Kong [1], and we supplemented our work in collaboration with students from the faculty of social science on the impacts on the quality of life of these patients and their next-of-kins. Quality of life was measured with the Chinese version of short form-36(More)
Cognition had recently been suggested as a supplement to traditional measures of neurological outcome. However, no data were available in the literature on long-term cognitive outcomes in patients with traumatic subarachnoid hemorrhage (tSAH). We explored the long-term cognitive profiles of patients with tSAH who had returned to the community, and the risk(More)
BACKGROUND Cognitive domain deficits can occur after aneurysmal subarachnoid haemorrhage (aSAH) though few studies systemically evaluate its impact on 1-year outcomes. OBJECTIVE We aimed to evaluate the pattern and functional outcome impact of cognitive domain deficits in aSAH patients at 1 year. METHODS We carried out a prospective observational study(More)
Although aneurysmal subarachnoid hemorrhage (aSAH) accounts for only 3-5% of all strokes, a high degree of morbidity has been reported in this relatively young subset of patients. Neuropsychiatric disturbance has often been neglected in these reports. We aimed to investigate the pattern and pathological factors of chronic neuropsychiatric disturbance in(More)
BACKGROUND The identification of aneurysmal subarachnoid hemorrhage (aSAH) patients with a decrease in health-related quality of life (HRQOL) is challenging. Failure of clinical trials has been partially attributed to lack of sensitivity in outcome measures. Stroke-specific Quality of Life (SS-QOL) is a disease-specific HRQOL tool widely applied in ischemic(More)
BACKGROUND The identification of aneurysmal subarachnoid hemorrhage (aSAH) patients with a decrease in health-related quality of life (HRQOL) is challenging. Stroke-Specific Quality of Life (SS-QOL) Scale is one of the commonest disease-specific quality of life measures initially developed and validated for ischemic stroke patients. A disadvantage is(More)
