Introduction: The main purpose of occluding a ruptured aneurysm is preventing rebleeding, which may be fatal. Microsurgical or endovascular treatments are the main approaches adopted to prevent new bleeding. Among patients presenting with aneurysmal subarachnoid hemorrhage, about 50% had permanent injuries. Cognitive changes are one of the main morbidities from that illness. The type of treatment for the aneurysm (clipping or coil embolization) can also contribute to the genesis of those complications.
Objective: Assessing language and verbal memory changes resulting from the aneurysmal lesion occlusion procedures, as well as establish which treatment offers less cognitive sequels.
Method: This investigation was carried out in Hospital da Restauraão, Recife-PE, from May 2007 to November 2009. One hundred fifty-one patients were divided into two groups, surgical and endovascular, and had their language, fluency, and verbal memory functions tested at two time points, pre- and postoperation. The results of the initial assessment and of the one occurring after the treatment were compared, between both groups and to each other.
Results And Conclusions: One hundred fifty-one patients were assessed, distributed as 122 surgical and 29 coil embolized. The performances in both groups did not differ in the initial assessment. However, endovascular treatment does not show additional cognitive impairment and had a better performance in language and verbal memory, compared with patients submitted to surgical treatment in an early postoperative period.

Electroconvulsive therapy (ECT) is an effective treatment for depression but is often associated with cognitive side effects. In patients, ECT-induced electric field (E-field) strength across brain regions varies significantly due to anatomical differences, which may explain individual differences in cognitive side effects. We examined the relationship between regional E-field strength and change in verbal fluency score (i.

Objective: To explore the effects of acupuncture in comparison with sham acupuncture on cognitive functions in patients with relapsing-remitting multiple sclerosis (RRMS).
Methods: In this randomized controlled trial, 31 RRMS patients in the acupuncture group were treated with traditional Chinese acupuncture based on the treatment principle of calming the mind, reinforcing qi and blood, and 31 patients in the control group were treated with sham acupuncture (shallow needling at non-acupuncture points) twice a week for 12 weeks. The primary outcome was the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) score, which was evaluated by a psychologist at baseline and after 12 weeks of treatment.

Schizophrenia (SZ) is a complex, chronic mental disorder characterized by positive symptoms (such as delusions and hallucinations), negative symptoms (including anhedonia, alogia, avolition, and social withdrawal), and cognitive deficits (affecting attention, processing speed, verbal and visuospatial learning, problem-solving, working memory, and mental flexibility). Extensive animal and clinical studies have emphasized the NMDAR hypofunction hypothesis of SZ. Glycine plays a crucial role as an agonist of NMDAR, enhancing the receptor's affinity for glutamate and supporting normal synaptic function and plasticity, that is, signal transmission between neurons.

Background: Cognitive impairment is common at all stages of Parkinson's disease (PD), but there is no consensus on which neuropsychological tests to use or how to interpret cognitive battery results. A cognitive summary score (CSS) combines the richness of a neuropsychological battery with the simplicity of a single score.
Objective: The objective of this study was to determine whether a CSS created using robust norming can detect early cognitive deficits in de novo, untreated PD.

Understanding brain function relies on identifying spatiotemporal patterns in brain activity. In recent years, machine learning methods have been widely used to detect connections between regions of interest (ROIs) involved in cognitive functions, as measured by the fMRI technique. However, it's essential to match the type of learning method to the problem type, and extracting the information about the most important ROI connections might be challenging.
