Frontoamygdala hyperconnectivity predicts affective dysregulation in adolescent moderate-severe TBI
Bickart, Kevin C.; Olsen, Alexander; Dennis, Emily L.; Babikian, Talin; Hoffman, Ann N.; Snyder, Aliyah; Sheridan, Christopher A.; Fischer, Jesse T.; Giza, Christopher C.; Choe, Meeryo C.; Asarnow, Robert F. (Peer reviewed; Journal article, 2022)In survivors of moderate to severe traumatic brain injury (msTBI), affective disruptions often remain underdetected and undertreated, in part due to poor understanding of the underlying neural mechanisms. We hypothesized ... -
Functional Brain Hyperactivations Are Linked to an Electrophysiological Measure of Slow Interhemispheric Transfer Time after Pediatric Moderate/Severe Traumatic Brain Injury
Olsen, Alexander; Babikian, Talin; Dennis, Emily L.; Ellis-Blied, Monica U.; Giza, Christopher C.; Marion, Sarah DeBoard; Mink, Richard; Johnson, Jeffrey; Babbitt, Christopher; Thompson, Paul M.; Asarnow, Robert F. (Peer reviewed; Journal article, 2020)Increased task-related blood oxygen level dependent (BOLD) activation is commonly observed in functional magnetic resonance imaging (fMRI) studies of moderate/severe traumatic brain injury (msTBI), but the functional ... -
Magnetic resonance spectroscopy of fiber tracts in children with traumatic brain injury: A combined MRS - Diffusion MRI study
Dennis, Emily L.; Babikian, Talin; Alger, Jeffry; Rashid, Faisal; Villalon-Reina, Julio E.; Jin, Yan; Olsen, Alexander; Mink, Richard; Babbitt, Christopher; Johnson, Jeffrey; Giza, Christopher C.; Thompson, Paul M.; Asarnow, Robert F. (Peer reviewed; Journal article, 2018)Traumatic brain injury can cause extensive damage to the white matter (WM) of the brain. These disruptions can be especially damaging in children, whose brains are still maturing. Diffusion magnetic resonance imaging (dMRI) ... -
Poorer sleep health is associated with altered brain activation during cognitive control processing in healthy adults
Smevik, Hanne; Habli, Sarah; Saksvik, Simen Berg; Kliem, Elisabeth; Evensmoen, Hallvard Røe; Conde, Virginia; Petroni, Agustin; Asarnow, Robert F.; Dennis, Emily L.; Eikenes, Live; Kallestad, Håvard; Sand, Trond Halfdan; Thompson, Paul M.; Saksvik-Lehouillier, Ingvild; Håberg, Asta; Olsen, Alexander (Peer reviewed; Journal article, 2023)This study investigated how proactive and reactive cognitive control processing in the brain was associated with habitual sleep health. BOLD fMRI data were acquired from 81 healthy adults with normal sleep (41 females, age ... -
The prevalence and stability of sleep-wake disturbance and fatigue throughout the first year after mild traumatic brain injury
Saksvik, Simen Berg; Karaliute, Migle; Kallestad, Håvard; Follestad, Turid; Asarnow, Robert F.; Vik, Anne; Håberg, Asta; Skandsen, Toril; Olsen, Alexander (Peer reviewed; Journal article, 2020)In this prospective, longitudinal study, we aimed to determine the prevalence and stability of sleep-wake disturbance (SWD) and fatigue in a large representative sample of patients (Trondheim mild traumatic brain injury ...
