Objective: To determine the difference in outcome among elderly people with major depression who do and do not have severe white matter lesions on magnetic resonance imaging.
Design: Follow up study.
Setting: Two psychiatric and two general hospitals in Melbourne, Australia.
Subjects: 60 depressed subjects aged over 55 referred to hospital psychiatric services with major depressive disorder meeting American Psychiatric Association (DSM-IIIR) criteria.
Main Outcome Measure: Proportion with good outcome as determined by full recovery from initial illness and no evidence of depressive relapse or cognitive decline during follow up among those with and without lesions.
Results: Mean (SD) follow up was 31.9 (9.9) months. Survival analysis showed a significant effect of severe lesions on time to poor outcome (P=0.04), with median survival 136 days in those with severe lesions compared with 315 days in those without.
Conclusion: Severe white matter change on magnetic resonance imaging is associated with poor outcome in elderly depressed subjects.

Perinatal white matter injury (WMI), which is prevalent in premature infants, involves M2 microglia affecting oligodendrocyte precursor cells (OPCs) through exosomes, promoting OPC growth and reducing WMI. The molecular mechanism of WMI remains unclear, and this study explored the role of M2 microglia-derived exosomes in WMI. A tMCAO rat model was constructed to simulate WMI characteristics in vivo.

Background: Cerebral infection with the opportunistic pathogen Bacillus cereus can lead to severe lesions, especially in premature newborns. Early diagnosis would be highly beneficial. The aim of this study was to describe the imaging findings associated with B.

Material And Methods: This retrospective observational study assessed 426 pediatric patients who underwent myelomeningocele repair between January 2013 and December 2020. Cranial MRIs with T1- and T2-weighted sequences were obtained as part of the postoperative assessment to determine the presence of associated supratentorial anomalies in pediatric patients following myelomeningocele repair.

Idiopathic epilepsy (IE) is the most common neurological disease in dogs. Approximately 1/3 of dogs with IE are resistant to anti-seizure medications (ASMs). Because the diagnosis of IE is largely based on the exclusion of other diseases, it would be beneficial to indicate an IE biomarker to better understand, diagnose, and treat this disease.

Background And Objective: Neurobrucellosis is a rare neurological disorder characterized by diverse clinical manifestations. Although several relevant cases were reported, our understanding of this disorder is limited. In this study, we presented the clinical and imaging characteristics of four cases of neurobrucellosis.
