However, most models failed to incorporate the biochemical and biophysical stimuli from fluid flow. (awionline.org)

CONCLUSIONS: Comparing older persons with and without MS, we provide compelling evidence of a double dissociation between the presence of mobility impairment and two neuroimaging markers of white matter integrity, fronto-striatal fractional anisotropy, and whole brain lesion load. (bvsalud.org)
If treated with cardiopulmonary resuscitation, however, cardiac arrest is survivable, but survivors often show evidence of injury in selectively vulnerable regions of the brain. (cdc.gov)

With animal models providing support for the concept, Dr Cuatrecasas, along with researchers at the Guttmann Institute, a neurorehabilitation hospital in Barcelona, set out to investigate the use of growth hormone in this patient population. (medscape.com)

The first model is formed of transgenic, 'Tau-GFP reporter' zebrafish in which the spread of the abnormal protein can be directly observed. (elifesciences.org)
Taupathies are syndromes that occur secondary to deposition of abnormal forms of tau protein in the brain. (medscape.com)
Pick disease is a taupathy, with accumulation of abnormal tau protein in the brain. (medscape.com)

Head injury is a broader category that may involve damage to other structures such as the scalp and skull. (wikipedia.org)
In addition to the damage caused at the moment of injury, a variety of events following the injury may result in further injury. (wikipedia.org)
Brain function is temporarily or permanently impaired and structural damage may or may not be detectable with current technology. (wikipedia.org)
Traumatic brain damage is common worldwide and the treatments are not defined. (researchsquare.com)

Rotational forces on the brain during acceleration-deceleration injuries cause widespread damage to axons in the white matter of the brain, and this should be suspected in a child when the degree of neurologic deterioration is out of proportion to a relatively unremarkable cranial computed tomography (CT) scan. (medscape.com)

To investigate mechanisms of injury and recovery in neonatal encephalopathy (NE), we performed targeted metabolomic analysis of plasma using liquid chromatography with tandem mass spectrometry (LC/MS/MS) from healthy term neonates or neonates with NE. (nature.com)
