This  phase 3 clinical trial , known as  TenCRAOS , investigated whether the drug  tenecteplase  could improve vision for patients suffering from  acute central retinal artery occlusion . Researchers compared the efficacy and safety of a  single intravenous injection  of the thrombolytic agent against a standard dose of  oral aspirin  when administered within a tight  4.5-hour window . The study f...

This episodes summarizes three papers on significant advancements and clinical recommendations for utilizing  blood-based biomarkers  to diagnose  Alzheimer’s disease  and other neurodegenerative conditions.

The  2026 American Heart Association and American Stroke Association guidelines  provide a comprehensive framework for the  early management of acute ischemic stroke . Developed by a  multidisciplinary writing group , the document updates clinical protocols for  prehospital coordination ,  emergency evaluation , and  advanced reperfusion therapies . Key recommendations endorse the use of  tenectep...

This review explores  multifocal motor neuropathy (MMN) , a rare autoimmune condition characterized by  progressive muscle weakness  and  motor conduction blocks . The paper details how the disease predominantly impacts the  distal upper limbs  of middle-aged men while sparing sensory functions.  Electrodiagnostic testing ,  nerve ultrasound , and  MRI  serve as vital tools for identifying nerve e...

Stiff-person syndrome (SPS)  is a rare  autoimmune neurological disorder  primarily defined by muscle rigidity and painful spasms caused by impaired inhibitory neurotransmission. This comprehensive review details how the condition often involves  antibodies against glutamic acid decarboxylase (GAD)  and can manifest in various forms, ranging from classical stiffness to complex  spectrum disorders...

This review article provides a comprehensive guide for  diagnosing and managing dementia with Lewy bodies (DLB) , a condition frequently prone to misidentification. The authors emphasize the importance of recognizing  core clinical features , such as  cognitive fluctuations, visual hallucinations, parkinsonism, and REM sleep behavior disorder . Beyond traditional symptoms, the text highlights  pro...

This research study presents a  systematic review and meta-analysis  of 224 patients to characterize  seronegative autoimmune encephalitis , a condition where individuals show symptoms of brain inflammation without detectable autoantibodies. The authors identify two primary categories— limbic encephalitis  and  antibody-negative probable autoimmune encephalitis —noting that the latter typically re...

This episode provides  updated clinical guidelines  for the  diagnosis and management  of cavernous malformations (CMs) within the brain and spinal cord.
