This clinical study explores associations among basal serum cortisol, depressive symptoms, and medial temporal lobe atrophy in patients with MCI and Alzheimer's disease. It discusses stress‑axis dysregulation as a potential contributor to neurodegeneration and outlines implications for assessment and intervention.
Temporal lobe meningoencephalocele is an uncommon anomaly in the face. As brain tissue herniate through the dural imperfection, cerebrospinal fluid (CSF) or a mass will appear in the mastoid, middle ear or the both. Here we present a 10 years old boy with right lobe temporal meningoencephalocele which results in CSF leakage and manifested with bacterial meningitis. He had a history of head trauma and bone fracture 3 years ago. In surgery the defect repaired and the patient showed improvement.
Although clinical trials in refractory epilepsy are currently carried out, the field of deep brain stimulation (DBS) in epilepsy is still at its initial stage. Little is known about where, when and how to stimulate and what would be the short and long consequences. Animal studies might provide clinicians with new ideas regarding targets for DBS. Here an overview is given regarding old and new targets in rodent models of temporal lobe epilepsy. The evidence from animal models showed that stimulation of the subiculum – either in responsive or scheduled manner - is anticonvulsant in different seizure and epilepsy models, indicating that the subiculum might be a promising candidate for DBS targets. For the rest, the antiepileptic effects of low frequency stimulation were established mostly in kindling models. The presence of a critical time window in which stimulation was effective following after discharges on kindling acquisition, demonstrates that timing of DBS is an important factor for the anticonvulsant effects of DBS.
