Objective: To detect changes in speech, verbal fluency, and memory in patients with subarachnoid hemorrhage (SAH) caused by ruptured aneurysms and to analyze the results before surgical or embolization procedure.
Methods: During the period May 2007 to November 2009, 193 patients with anterior aneurysmal SAH admitted to the Department of Neurosurgery, Hospital da Restauração, Recife, Brazil, were tested for speech, verbal fluency, and memory disturbances after the first week of bleeding and compared with a control group with similar demographics.
Results: Patients with aneurysmal SAH differed significantly from the control group in language, verbal fluency, and memory functions before clipping or coiling procedures. There were differences in cognitive performance between patients with different aneurysm sites.
Conclusions: It was possible to characterize the cognitive impairments of each area affected early on in the preoperative period, confirming the assumptions that the aneurysm site could be a determining factor of cognitive impairment.

Intermittent theta burst stimulation for negative symptoms in schizophrenia patients with mild cognitive impairment: a randomized controlled trail.
Front Psychiatry
January 2025
Mental Health Center and Psychiatric Laboratory, the State Key Laboratory of Biotherapy, West China Hospital, Sichuan University, Chengdu, China.
Background: This study aims to evaluate the intervention effect of intermittent Theta burst stimulation (iTBS) on bilateral dorsomedial prefrontal cortex (DMPFC) for negative symptoms in schizophrenia using functional near-infrared spectroscopy (fNIRS) to confirm the therapeutic significance of DMPFC in treating negative symptoms and provide new evidence for schizophrenia treatment and research.
Method: Thirty-nine schizophrenia patients with negative symptoms and mild cognitive impairment were randomly divided into a treatment group (n=20) and a control group (n=19). The treatment group received iTBS in bilateral DMPFC.
Neighborhood-level socioeconomic disadvantage is associated with multiple cognitive domains in a community sample of older adults.

Greater neighborhood disadvantage is associated with poorer global cognition. However, less is known about the variation in the magnitude of neighborhood effects across individual cognitive domains and whether the strength of these associations differs by individual-level factors. The current study investigated these questions in a community sample of older adults ( = 166, mean age = 72.

Unlabelled: Greater empirical and scientific attention is still put on patients with left brain hemisphere (LBH) damage where language impairments are common and expected. In patients with RBH damage, language assessment is therefore rarely done in the acute phase of stroke recovery.
Purpose: To investigate language impairments in the acute phase of stroke using a Croatian standardized language battery for the first time and compare patients with RBH stroke, LBH stroke and healthy individuals.
Reliability and validity of the unhelpful thoughts and beliefs scale for Persian-speaking adults who stutter (UTBAS-P): A cross-cultural examination of social anxiety in people who stutter.

Faculty of Health, Charles Darwin University, Australia. Electronic address:
Background And Aim: An increasing body of research indicates that many adults who stutter (AWS) experience anxiety in social and verbal situations. The Unhelpful Thoughts and Beliefs about Stuttering (UTBAS) scales were developed to assess speech-related anxiety and negative cognitions associated with stuttering. This study aimed to translate the UTBAS into Persian, investigate its psychometric properties for Persian-speaking AWS, and compare the results with previously published UTBAS scores across various cultures.

Introduction: Studies about dementia in Indigenous communities are still scarce worldwide, especially in low-middle-income countries, limiting timely intervention in minority groups. Our research aimed to bridge this gap by determining the prevalence of dementia and mild cognitive impairment no dementia (CIND), and the associated factors, in a multiethnic Indigenous community in Manaus, Brazil.
Methods: A cross-sectional observational study evaluated the cognitive and functional performances of 141 Indigenous individuals (aged 50 and above).
