Hace 5 días · As such, CSF tracer influx into the trigeminal ganglion can take two paths, either flowing from the inner subarachnoid space surrounding the root of the nerve, where no barriers are present, or via the brainstem parenchyma, via the pons and the trigeminal nerve to the ganglion [see (1) and (2) in Fig. 2D].
21 de jun. de 2024 · In iNPH, the perivascular spaces of the subarachnoid space (PVSAS) exhibit dysfunction, characterized by widened PVSAS areas and slowed perivascular tracer transport . This is accompanied with enhanced tracer enrichment in the brain and slowed clearance, likely due to impaired glymphatic transport.
Hace 6 días · Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is a syndrome with signs and symptoms of increased intracranial pressure but where a causative mass or hydrocephalus is not identified.
Hace 6 días · The subarachnoid lymphatic-like membrane is only a few cells thin layer, which renders it invisible using clinical neuroimaging techniques. The SLYM forms a barrier through which cerebrospinal fluid solutes over 3 kDa cannot pass, thus it divides the subarachnoid space into two distinct compartments 1 .
2 de jul. de 2024 · Normal pressure hydrocephalus (NPH) is a clinical condition characterised by the triad of gait disturbance, dementia, and urinary incontinence, alongside radiological evidence of ventricular enlargement without significant elevation in cerebrospinal fluid (CSF) pressure.
2 de jul. de 2024 · Subarachnoid hemorrhage (SAH) from spontaneous rupture of an aneurysm is a debilitating condition with high morbidity and mortality.
