- Magnetic seizure therapy offers a promising alternative for treatment-resistant depression by potentially preserving cognitive function while maintaining the high antidepressant efficacy characteristic of convulsive therapies.
- Single-nucleus RNA sequencing reveals that Alzheimer's neurodegeneration follows an asynchronous, continuous trajectory with distinct transcriptional inflection points creating a permissive environment for tau pathology.
- Clozapine rechallenge following mandated cessation for suspected neutropenia is a viable strategy for selected patients, offering a potential pathway to resume effective treatment.
- Employment significantly reduces the prevalence of severe post-traumatic stress symptoms among refugees, highlighting work access as a critical mental health intervention.
- The hippocampal-to-ventricle ratio (HVR) offers a robust, head-size-independent biomarker for Alzheimer's risk that reveals consistent female cognitive advantages and male-specific ventricular expansion patterns.
- Double-blind evidence indicates that frequency-specific event-related desynchronization in neurofeedback predicts long-term resting-state plasticity rather than immediate within-session shifts.
