Introduction: Poor quality sleep has often been cited as a cause of lowered quality of life in patients with affective disorders such as major depressive disorder (MDD) and generalized anxiety disorder (GAD). As sleep and affective disorders are affected by multi-network interactions, we hypothesize that the modulation of the central executive network (CEN), salience, and default mode networks (DMNs) through individualized repetitive transcranial magnetic stimulation (rTMS) may improve sleep and quality of life.

Methods: A retrospective analysis from 2020 to 2023 was conducted in patients with affective disorders at Cingulum Health.

Article Synopsis
  • Clinical clearance of a child's cervical spine after trauma is difficult due to unreliable neurologic exams; LSMRI may help by providing a quicker, anesthesia-free alternative to standard MRI for detecting ligamentous injuries.
  • A study conducted over five years across 10 centers evaluated 2,663 children and found that LSMRI had a sensitivity and negative predictive value of over 99% for detecting cervical spine injuries and 100% for unstable injuries.
  • The findings support the use of limited-sequence MRI to effectively rule out significant injuries, suggesting that trauma centers implement LSMRI protocols to reduce the need for anesthesia and MRI times.
