The purpose of this study was to evaluate the rate and timing of neurological recovery in cats with epidural lymphoma who were treated with chemotherapy. The study included cats with various degrees of neurological impairment, confirmed diagnosis of lymphoma and spinal cord involvement. At the start of treatment, of the 14 cats diagnosed with lymphoma, 14.3% (n = 2) had ambulatory paraparesis, 14.3% (n = 2) had non-ambulatory paraparesis, 7.1% (n = 1) paraplegia with deep nociception, 50% (n = 7) were paraplegic with absent deep nociception and 14.3% (n = 2) had non-ambulatory tetraparesis. The chemotherapy treatment given was COP in 10 cats, COP and CHOP in 2 cats and CHOP in 2 cats. The number of chemotherapy sessions needed for neurological recovery varied from 1 to 4, with a total of 1-13 sessions per cat. The rate of neurological recovery was satisfactory in 83.3% (10/12) of the cats. This study indicates that cats with epidural lymphoma treated with chemotherapy have an 83.3% likelihood of partial neurological recovery and a 50% chance of full neurological recovery within a period of 7-28 days, regardless of the level of neurological impairment.

Background: Women are disproportionately affected by neuropsychiatric symptoms following recovery from acute COVID-19. However, whether there are central nervous system-specific changes in gene expression in women with neuropsychiatric Long COVID (NP-Long COVID) remains unknown.
Methods: Twenty-two women with and ten women without NP-Long COVID were enrolled from New Haven, CT, and the surrounding region and consented to a blood draw and large volume lumbar puncture.

Background: The "Systematic Screening of Handwriting Difficulties in Parkinson's Disease" (SOS) test is the only tool specifically designed to evaluate handwriting in people with Parkinson's Disease (pwPD). It is language specific.
Objective: To assess the construct validity, intrarater and interrater reliability of the Italian version of the SOS test.

The role of the right hemisphere in aphasia recovery has been controversial since the 19th century. Imaging studies have sometimes found increased activation in right hemisphere regions homotopic to canonical left hemisphere language regions, but these results have been questioned due to small sample sizes, unreliable imaging tasks, and task performance confounds that affect right hemisphere activation levels even in neurologically healthy adults. Several principles of right hemisphere language recruitment in aphasia have been proposed based on these studies: that the right hemisphere is recruited primarily by individuals with severe left hemisphere damage, that transcallosal disinhibition results in recruitment of right hemisphere regions homotopic to the lesion, and that increased right hemisphere activation diminishes to baseline levels over time.

Traumatic Brain Injury (TBI) is a common and debilitating injury, causing long-lasting neurological deficits. Current therapeies for recovery remain inadequate, undersing the urgent need for innovative interventions. In this study, a novel therapeutic approach is introduced that delivers extracellular vesicles (EVs) derived from human-induced pluripotent stem cell-derived neural progenitor cells (hiPSC-NPCs) with a gelatin-based injectable bioorthogonal hydrogel (BIOGEL).

Background: Germinal matrix hemorrhage (GMH) is a common complication of premature infants with lifelong neurological consequences. Inflammation-mediated blood-brain barrier (BBB) disruption has been implicated as a main mechanism of secondary brain injury after GMH. The cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS)-stimulator of interferon genes (STING) pathway plays a crucial role in inflammation, yet its involvement in GMH pathophysiology remains unclear.
