Hyperphosphorylated Tau and Cognition in Epilepsy.
J Clin Med

Department of Epileptology, University Hospital Bonn (UKB), 53127 Bonn, Germany.
In light of the growing interest in the bidirectional relationship between epilepsy and dementia, this review aims to provide an overview of the role of hyperphosphorylated tau (pTau) in cognition in human epilepsy. A literature search identified five relevant studies. All of them examined pTau burden in surgical biopsy specimens from patients with temporal lobe epilepsy.

The patients with Arthrogryposis-Renal dysfunction-Cholestasis (ARC) syndrome have genetic susceptibility to the opportunistic infections due to the involvement of VPS33B (vacuolar protein sorting 33 homolog B) in phagolysosome fusion in macrophages. Detailed pathologic studies in ARC patients are missing in literature due to the lack of autopsy. We described the first autopsy case of ARC syndrome in a 2-month-old male infant.

Buspirone, a commonly prescribed medication for generalized anxiety disorder (GAD), is gaining attention for its narrow window of side effects such as lack of physical dependence, non-sedative properties as compared to other anxiolytic drugs. Its dose-specific therapeutic effects beyond anxiety highlights its clinical significance. Pharmacologically, buspirone activates serotonin-1A pre-synaptic autoreceptors and post-synaptic heteroreceptors which modulate serotonergic neurotransmission induced behavioral changes such as anxiolytic and nootropic effects.

The neuropathological diagnosis of Alzheimer's disease (AD) relies on amyloid beta (Aβ) deposition in brain tissues. To study the relationship between Aβ deposition and brain structure, as determined using C-Pittsburgh compound B (PiB) and magnetic resonance imaging (MRI), respectively, we developed a regression model with PiB and MRI data as the predictor and response variables, respectively, and proposed a regression method for studying the association between them based on a supervised sparse multivariate analysis with dimension reduction based on a composite paired basis function. By applying this method to imaging data of 61 patients with AD (age: 55-85), the first component showed the strongest correlation with the composite score, owing to the supervised feature.
