[Influence of Pre-existing Cognitive Impairment on Rehabilitation Outcomes in Patients with Cerebral Infarction].

Background And Purpose: The present study determined the effects of pre-existing cognitive impairment (PreCI) on the rehabilitation outcomes in patients with cerebral infarction.

Methods: From June 2013 to August 2015, we classified 52 patients with unilateral cerebral hemispheric infarction into the PreCI and non-PreCI group based on three-dimensional stereotactic surface projection (3D-SSP) cerebral blood flow (CBF) decrease images and the past history of dementia. Furthermore we investigated the related clinical factors and functional independence measure (FIM).

Prediction of stroke rehabilitation outcome with xenon-enhanced computed tomography cerebral blood flow study.

Background: Cerebral blood flow (CBF) of stroke patients in the chronic stage is supposed to reflect brain functions. We examined the relation between rehabilitation outcome and CBF values.

Methods: The study group comprised 101 consecutive patients (mean age, 69±12 years) including 61 patients with cerebral infarction, 32 patients with cerebral hemorrhage, and 8 patients with subarachnoid hemorrhage.

[Evaluation of cerebral hemodynamics with perfusion CT].

We report on the evaluation of cerebral ischemic lesions with perfusion CT. Cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT) of 52 patients mostly with ischemic cerebrovascular disease were analysed using the box-modulation transfer function method with 30 ml of contrast medium intravenously injected at 5 ml/sec. CBF, CBV and MTT of the middle cerebral artery (MCA) territory were 43.
