Standardized clinical behavioral assessment remains the cornerstone for diagnosing disorders of consciousness (DoC). Nevertheless, mounting evidences underscore the substantial risk of misdiagnosis associated with exclusive reliance on behavioral evaluations. In contemporary neuroscience research, advanced neuroimaging and electrophysiological methodologies have emerged as powerful tools; these techniques not only enable in-depth characterization of the dynamic alterations in brain structure and function among DoC patients but also furnish critical insights for clinical decision-making, including accurate diagnosis, prognosis, and tailored therapeutic strategies. This review synthesizes the recent advance in applying neuroimaging and electrophysiological approaches in DoC diagnosis and prognosis evaluation, and discusses its technical advantages, clinical application scenarios and limitations, in order to provide new ideas and methods for DoC diagnosis and prognosis evaluation.

Hematoma enlargement is a common harmful event after cerebral hemorrhage, which can lead to deterioration of neurological function and poor outcome. Early detection of high-risk patients can help prevent hematoma enlargement and improve the outcome of patients. Although the exact mechanism of hematoma enlargement is unclear, more and more evidence shows that many imaging signs may be related to hematoma enlargement, such as dot sign, mixed sign, black hole sign, island sign, etc. This article mainly reviews the relevant imaging prediction factors of hematoma enlargement from the perspective of imaging.

Objective To discuss the mechanism of progesterone that soften brain water content in traumatic brain edema in rats. Methods The models of focal lobe contusion and laceration of brain were made on the male rats treated by the progesterone following injury. Immunohistochemical method was used to assess the expression of aquaporin-4 (AQP4). Evan's Blue method was used to detect the permeability of blood-brain barrier. Results Treated by the progesteron, the brain water content was significantly decreased, and the lower expression of AQP4 took place on astrocytes of the contusion and peri-contusion of the brain tissue after 24 h,72h ,and 120h . The content of EB was decreased at 6 h and 24 h post-injury. Conclusions Progesterone can soften the traumatic brain water content, which may be associated with the attenuation of AQP4 in frontal lobe contusion following traumatic brain injury ( TBI) and progesterone can protect the blood-brain barrier at early time after TBI.
