AI Article Synopsis
- A 70-year-old man was hospitalized due to dizziness and unsteadiness, but initial MRI showed no brain abnormalities.
- On Day 1, he developed respiratory failure, and by Day 3, he exhibited flaccid tetraplegia, leading to his transfer to another hospital.
- Follow-up MRI on Day 6 revealed bilateral medial medulla infarction, highlighting the importance of considering this condition in cases of progressive tetraplegia and the necessity of follow-up imaging for accurate diagnosis.
Article Abstract
A 70-year-old man presented with dizziness and unsteadiness when standing and was hospitalized in another hospital. Magnetic resonance imaging (MRI) of the brain on Day 1 showed no abnormalities. The patient developed respiratory failure on Day 1and flaccid tetraplegia on Day 3, and was transferred to our hospital. Progressive upper and lower limb weakness and bulbar symptoms suggested Guillain-Barré syndrome or its variant. Diffusion-weighted MRI on Day 6 disclosed high signal intensities in the bilateral medial portion of the medulla, and the patient was diagnosed with bilateral medial medulla infarction. Bilateral medial medulla infarction should be considered when a patient shows progressive tetraplegia, and bulbar palsy and follow-up MRI is important to confirm the diagnosis.

Brainstem BDNF neurons are downstream of GFRAL/GLP1R signalling.
Nat Commun

Growth differentiation factor 15, GDF15, and glucagon-like peptide-1 (GLP-1) analogues act through brainstem neurons that co-localise their receptors, GDNF-family receptor α-like (GFRAL) and GLP1R, to reduce food intake and body weight. However, their use as clinical treatments is partially hampered since both can also induce sickness-like behaviours, including aversion, that are mediated through a well-characterised pathway via the exterolateral parabrachial nucleus. Here, in mice, we describe a separate pathway downstream of GFRAL/GLP1R neurons that involves a distinct population of brain-derived neurotrophic factor (BDNF) cells in the medial nucleus of the tractus solitarius.

Traumatic brain injury (TBI) after high-energy, behind helmet blunt trauma (BHBT) is an important but poorly understood clinical entity often associated with apnea and death in humans. In this study, we use a swine model of high-energy BHBT to characterize key neuropathologies and their association with acute respiratory decompensation. Animals with either stable or critical vital signs were euthanized within 4 h after injury for neuropathological assessment, with emphasis on axonal and vascular pathologies in the brainstem.

A 52-year-old man with a 5-year history of diabetes mellitus and chronic renal disease presented with sudden onset left upper limb weakness and numbness at 5 pm, which progressed to quadriplegia by the next day at 2:30 am. He had dysarthria at admission. There were no sensory symptoms in the lower limbs.

Article Synopsis
- Research indicates that structural and functional brain changes are linked to opioid use disorder (OUD), but earlier studies often had small participant groups, especially fewer women, and focused on single types of brain analysis.
- This study aimed to use comprehensive brain imaging techniques, including T1-weighted MRI and resting-state fMRI, to better identify these brain alterations in OUD patients undergoing methadone treatment compared to healthy controls.
- Results showed significant differences in brain volumes between the two groups, with OUD participants having smaller thalamus and temporal lobe sizes but larger brainstem and cerebellum volumes, and there were sex-based differences in the medial prefrontal cortex volumes.

Bilateral medullary syndrome (BMS) is an extremely rare and devastating neurological disorder resulting from ischemia or infarction of the medulla oblongata. This case report presents two unique instances of BMS, both leading to fatal outcomes. Case 1 describes a 70-year-old male with a history of systemic hypertension who presented with limb weakness, slurred speech, and dysphagia.
