Article Abstract
Purpose: The current study aims to explore the correlation between the Diffusion Tensor Imaging (DTI) indices and neurological status of individuals with TB spine with neurological deficit (TBSND). Further, factors affecting the rate of post-operative neurological recovery were also analysed with special emphasis on DTI indices.
Methods: The current study included 51 individuals with TBSND undergoing posterior instrumentation and posterolateral decompression. All individuals underwent DTI scanning at the site of compression and at a normal level proximal to the disease. The relationship of the DTI parameters with the pre-operative motor, sensory and total scores were analysed. All clinical and radiological parameters were further analysed on the basis of their recovery patterns after decompression surgery.
Results: The FA values at the compressed segment were significantly lower while the ADC values were significantly higher when compared with the non-compressed levels. Pre-operative motor and total neurological scores were found to be significantly positively correlated to FA values and ADC values. Faster neurological recovery after decompression was associated with high FA values and younger age while incomplete neurological recovery was associated with high ADC values.
Conclusions: Higher FA indices along with lower age constitute independent predictors for faster neurological recovery following decompression. FA values correlate with the neurological status of individuals with TBSND and its use may be explored as an adjunct to objectively assess the cord damage and for predicting neurological recovery pattern after decompression in such individuals.

Background: There is limited knowledge on the post-glymphatic structures such as the parasagittal dural (PSD) space and the arachnoid granulations (AGs) in multiple sclerosis (MS).
Objectives: To evaluate differences in volume and macromolecular content of PSD and AG between people with newly diagnosed MS (pwMS), clinically isolated syndrome (pwCIS), or radiologically isolated syndrome (pwRIS) and healthy controls (HCs) and their associations with clinical and radiological disease measures.
Methods: A total of 69 pwMS, pwCIS, pwRIS, and HCs underwent a 3.
Ivermectin toxicosis in a foal: Use of intravenous lipid emulsion therapy.

This report describes a case of ivermectin toxicosis in a 4-day-old thoroughbred colt successfully treated with intravenous lipid emulsion (ILE) without complications. This case supports the use of ILE as a safe and effective therapy for the management of lipophilic drug toxicosis in foals. Key clinical message: Ivermectin toxicosis, though rare in equine neonates, can occur following accidental overdose and induces severe neurologic signs.

Background: Idiopathic normal pressure hydrocephalus (iNPH) predominantly manifests with gait disturbances, yet clinical assessments are vulnerable to confirmation bias, particularly post-shunt surgery. Blinded video evaluations are a method to enhance objectivity in gait assessment, but their reliability has never been systematically investigated. The aim was to evaluate the inter-rater reliability of blinded gait assessments in iNPH patients and to investigate how these assessments correlate with the Hellström iNPH scale and patient-reported health status following shunt surgery.

Background And Purpose: Low-level light therapy (LLLT) has been shown to modulate recovery in patients with traumatic brain injury (TBI). However, the longitudinal impact of LLLT on brain metabolites has not been studied. The purpose of this study was to use magnetic resonance spectroscopic imaging (MRSI) to assess the metabolic response of LLLT in patients with moderate TBI at acute (within 1 week), subacute (2-3 weeks), and late-subacute (3 months) recovery phases.

Background: Intracranial solitary fibrous tumors (SFTs) are rare mesenchymal tumors often presenting with dural-based lesions. These tumors can exhibit aggressive characteristics with high recurrence rates and extracranial metastasis. While SFTs occasionally invade venous sinuses, cases where the tumor arises within the venous sinus are rare.
