We report a 34-year-old male neuroBehçet's Disease (NBD) patient with atypical magnetic resonance imaging (MRI) findings, whose behavioral problems were followed by progressive neurological symptoms. The patient was hospitalized due to forgetfulness, irritability, behavioral dyscontrol and a choking sensation. T2-weighted MRI showed prominent atrophy of cerebellar hemispheres, the cerebellar peduncle, the midbrain and the pons. He was diagnosed with NBD after an evaluation of his medical history together with neuropsychiatric and laboratory findings. There are few reports of NBD with only brainstem and cerebellar atrophy. We discuss our patient in the context of the four previously reported cases. In NBD without evident mucocutaneo-ocular symptoms, neurologists should always consider the medical and family history. Early diagnosis of NBD helps to initiate appropriate treatment, thereby modulating the course of the disease and preventing complications.

Brainstem infarct from cervical vertebral artery dissection presenting as a transient Parinaud syndrome.
Am J Ophthalmol Case Rep

Purpose: To report a case of transient diplopia and upgaze paresis in the setting of acute dorsal midbrain infarcts from a cervical vertebral artery dissection in an otherwise healthy man.
Observations: A 33-year old man presented to the ophthalmology urgent clinic with a 1 h history of blurred and double vision, asthenopia, and a mild focal left posterior headache. Ocular motility examination revealed a profound upgaze palsy and convergence-retraction horizontal jerk nystagmus in attempted upgaze that gradually improved over the course of 1 h.
Neuronal dynamics of cerebellum and medial prefrontal cortex in adaptive motor timing.

Precise temporal control of sensorimotor coordination and adaptation is a fundamental basis of animal behavior. How different brain regions are involved in regulating the flexible temporal adaptation remains elusive. Here, we investigated the neuronal dynamics of the cerebellar interposed nucleus (IpN) and the medial prefrontal cortex (mPFC) neurons during temporal adaptation between delay eyeblink conditioning (DEC) and trace eyeblink conditioning (TEC).

Paraneoplastic cerebellar degeneration (PCD) is a rapidly progressive, immune-mediated syndrome characterized by the degeneration of Purkinje cells, often associated with the presence of antibodies targeting intracellular antigens within these cells. These autoantibodies are implicated in the induction of cytotoxicity, leading to Purkinje cell death, as demonstrated in in vitro models. However, the precise roles of antibodies and T lymphocytes in mediating neuronal injury remain a subject of ongoing research, with T cells appearing to be the main effectors of cerebellar injury.

Objective: Postoperative tracheostomy is a significant complication following medulloblastoma (MB) resection. This study aimed to develop a predictive model for postoperative tracheostomy requirement in children undergoing MB surgical resection. This model was derived as a side product of a larger research project analyzing surgical outcomes in pediatric MB patients.

The cerebellum is involved in non-motor processing, supported by topographically distinct cerebellar activations and closed-loop circuits between the cerebellum and the cortex. Disruptions to cerebellar function may negatively impact prefrontal function and processing. Cerebellar resources may be important for offloading cortical processing, providing crucial scaffolding for normative performance and function.
