Switching attention deficits in post-stroke individuals with different aphasia types.

Background: Previous studies have shown that individuals with aphasia have impairments in switching attention compared to healthy controls. However, there is insufficient information about the characteristics of switching attention within one task and whether attention deficits vary depending on aphasia type and lesion location. We aimed to address these knowledge gaps by investigating characteristics of switching attention within one type of task in participants with different types of aphasia and distinct lesion sites.

[Dual-tasks is an indicator of cognitive deficit specificity in patients after traumatic brain injury].

Aim: To investigate the brain activity impairment in patients after traumatic brain injury (TBI) during dual-tasks in comparison with the normal ranges.

Material And Methods: Electroencephalographic (EEG), stabilographic and clinical study was performed in 9 patients (mean age 25±1.2 years) for up to 3 months after a mild traumatic brain injury (TBI) in comparison with 18 healthy subjects (mean age 26.

[Regression of post-stroke aphasia and associated non-speech syndromes caused by a course of restorative treatment including intensive speech therapy].

Aim: To analyze clinical and fMRI indicators related with the therapeutic effectiveness of complex restorative treatment including intensive speech therapy in various clinical forms and severity of the aphasia syndrome.

Material And Methods: The study included 40 right-handed patients with aphasia syndrome after the first hemispheric ischemic stroke. Patients were studied 3 month after disease onset.

[The prognosis for post-stroke aphasia].

Aim: To determine risk factors and factors of favorable prognosis for regression of post-stroke aphasia in the early recovery period of ischemic stroke (IS).

Material And Methods: A cohort study was undertaken with 40 patients with different clinical forms of aphasia. The duration of study was 3-4 months of the disease.

Neural mechanisms of two different verbal working memory tasks: A VLSM study.

Currently, a distributed bilateral network of frontal-parietal areas is regarded as the neural substrate of working memory (WM), with the verbal WM network being more left-lateralized. This conclusion is based primarily on functional magnetic resonance imaging (fMRI) data that provides correlational evidence for brain regions involved in a task. However, fMRI cannot differentiate the areas that are fundamentally required for performing a task.
