AI Article Synopsis
- The study aimed to investigate cognitive and emotional changes in patients with neurobrucellosis compared to those with brucellosis without neurological signs.
- Before treatment, patients with neurobrucellosis scored lower on cognitive (MMSE) and emotional (HDRS) tests, but their scores improved significantly within two weeks of antibiotic therapy.
- The findings suggest that cognitive and emotional issues in neurobrucellosis patients can be alleviated through antibiotics alone, without the need for additional psychiatric medications.
Article Abstract
Objective: To determine cognitive and emotional changes among neurobrucellosis patients.
Methods: The patients with neurobrucellosis and controls with brucellosis without neurologic involvement were included in the study. Neurobrucellosis was diagnosed by the following criteria: (i) symptoms or clinical findings compatible with neurobrucellosis, including headache, confusion, mental and emotional changes; (ii) isolation of Brucella spp. from CSF and/or demonstration of antibodies to Brucella > or = 1/4 in the CSF; (iii) the presence of lymphocytosis, increased protein and decreased glucose levels in the CSF; and (iv) clinical improvement with appropriate treatment. Two psychiatrists interviewed the patients, and performed the Hamilton Depression Rating Scale (HDRS) tests and Mini-Mental State Examination (MMSE) tests.
Results: Thirty-four neurobrucellosis cases and 30 patients with brucellosis without neurological involvement were studied. The mean age was 41 years, 12 (41%) patients were female, 13 (46%) patients were farmers, and 7 (25%) patients were housewives. Among the neurobrucellosis cases, before the antibiotic therapy, the mean MMSE test score was 21.6, one week after the therapy 22.7, and two weeks after the therapy 24.3 (p=0.024, and p<0.001, respectively). At the day of admission before therapy, the mean of HDRS test was 9.9, one week after therapy it was 7.8, and two weeks after therapy it was 5 (p=0.014, and p<0.001, respectively).
Conclusion: The cognitive and emotional disturbances among neurobrucellosis patients were documented by MMSE and HDRS tests. These disorders improve by antibiotic therapy, without any anti-depressive or anti-psychotic therapy.

Aberrant large-scale resting-state functional connectivity (rsFC) has been frequently documented in ischemic stroke. However, it remains unclear about the altered patterns of within- and across-network connectivity. The purpose of this meta-analysis was to identify the altered rsFC in patients with ischemic stroke relative to healthy controls, as well as to reveal longitudinal changes of network dysfunctions across acute, subacute, and chronic phases.

The subiculum is a main output part of the hippocampal formation and important for learning and memory. According to connection studies, the distal and proximal regions of the subiculum project to the brain regions related to the spatial and emotional memories, respectively. Our previous morphological studies indicated that the ventral subiculum (vSub) consists of two regions, the distal subiculum (Sub1) and the proximal subiculum (Sub2), while the dorsal subiculum (dSub) seemed to comprise only one region (Sub1).

Sleep is crucial for sustaining normal physiological functions, and sleep deprivation has been associated with increased pain sensitivity. The histone deacetylases (HDACs) are known to significantly regulate in regulating neuropathic pain, but their involvement in nociceptive hypersensitivity during sleep deprivation is still not fully understood. Utilizing a modified multi-platform water environment technique to establish a sleep deprivation model.

Introduction: Residual dizziness (RD) is common in patients with benign paroxysmal positional vertigo (BPPV) after successful canalith repositioning procedures. This study aimed to investigate the therapeutic effects of vestibular rehabilitation (VR) on BPPV patients experiencing RD, and to explore the impact of VR on functional connectivity (FC), specifically focusing on the bilateral parietal operculum (OP) cortex.
Methods: Seventy patients with RD were randomly assigned to either a four-week VR group or a control group that received no treatment.

Objective: The study was conducted to determine the effect of emotional freedom techniques (EFT) on the severity of premenstrual syndrome (PMS).
Methods: The study was conducted as a randomized controlled trial, with a premenstrual syndrome sample comprising 78 single female students of reproductive age presenting with PMS complaints (40 in the experimental group and 38 in the control group). Students in the experimental group were interviewed individually in the week before their menstrual cycle and received two EFT sessions with a 3-day interval.
