Second-line cannabis therapy in patients with epilepsy.

Objective: Marijuana-based therapies (MBTs) have been shown to reduce seizure frequency in patients with severe and drug-resistant epilepsy (DRE). Pharmaceutical-grade CBD (Epidiolex) was approved by the FDA in 2018 for the treatments of Dravet Syndrome (DS) and Lennox-Gastaut Syndrome (LGS) and subsequently in 2020 for tuberous sclerosis complex (TSC). It is unclear what the utility would be in prescribing one type of MBT if a previous, alternative type failed.

Longitudinal cognitive assessment in patients with primary CNS lymphoma treated with induction chemotherapy followed by reduced-dose whole-brain radiotherapy or autologous stem cell transplantation.

Introduction: The standard treatment for primary central nervous system lymphoma (PCNSL) involves induction methotrexate-based chemotherapy with or without consolidation whole brain radiotherapy (WBRT). As WBRT carries a substantial risk for cognitive impairment, alternative consolidation treatments have been used to reduce neurotoxicity, including reduced-dose WBRT (rdWBRT) or high-dose chemotherapy with autologous stem cell transplant (HDC-ASCT). In this study, we characterized cognitive functions in PCNSL patients achieving long-term remission following rdWBRT or HDC-ASCT.

Genetic variants and cognitive functions in patients with brain tumors.

Background: Patients with brain tumors treated with radiotherapy (RT) and chemotherapy (CT) often experience cognitive dysfunction. We reported that single nucleotide polymorphisms (SNPs) in the APOE, COMT, and BDNF genes may influence cognition in brain tumor patients. In this study, we assessed whether genes associated with late-onset Alzheimer's disease (LOAD), inflammation, cholesterol transport, dopamine and myelin regulation, and DNA repair may influence cognitive outcome in this population.
