A 65-year-old female patient underwent conservative management for cerebral infarcts in the bilateral thalamus and midbrain at the department of neurology of a university hospital (Fig. 1a). At fourweeks after onset, she was transferred to the rehabilitation department for rehabilitation. The patient showed impaired consciousness, with a Glasgow Coma Scale score of 13 and Coma Recovery Scale-Revised score of 15. Four agematched female control subjects (mean age: 65·28 years) were recruited… Expand

TLDR
In conclusion, this is the first study to demonstrate injury of the lower ARAS between the pontine reticular formation and the thalamus in a patient with IVH. Expand
Impaired consciousness due to injury of the ascending reticular activating system in a patient with bilateral pontine infarction: A case report
TLDR
This is the first report of injury to the ARAS in bilateral pontine infarction diagnosed by DTT, and results of diffusion tensor tractography showed decreased neural connectivity in the left lower dorsal ARAS, both lower ventral AR AS, and both upper ARAS. Expand
Injury of the lower ascending reticular activating system in patients with pontine hemorrhage
TLDR
In conclusion, injury of the lower ventral and dorsal ARAS was demonstrated in patients with impaired arousal following pontine hemorrhage, and it is believed that analysis of the ARAS using DTT would be helpful in evaluation of patients with impairment of consciousness after pontin hemorrhage. Expand
Recovery of multiply injured ascending reticular activating systems in a stroke patient
TLDR
A stroke patient with a spontaneous intraventricular hemorrhage and left basal ganglia hemorrhage is reported on who showed recovery of a multiply injured ARAS using DTT. Expand
Multiple injuries of the ascending reticular activating system in a stroke patient: a diffusion tensor tractography study
TLDR
The patient exhibited impaired alertness, and brain MR images at 6 weeks after onset showed multiple leukomalactic lesions in both fronto-parietal lobes, and narrowing of the right ventral lower ARAS was observed, indicating the ARAS is vulnerable to multiple brain pathologies. Expand

Recovery of injured lower portion of the ascending reticular activating system in a patient with traumatic brain injury.
TLDR
Recovered lower portion of the ascending reticular activating system (ARAS) between the pontine reticular formation and the thalamus in a patient with traumatic brain injury is demonstrated. Expand
Aneurysmal Subarachnoid Hemorrhage Causes Injury of the Ascending Reticular Activating System: Relation to Consciousness
TLDR
Injuries of the lower portion of the ascending reticular activating system between the pontine reticular formation and the thalamus are found in patients with SAH and a close association between injury and consciousness level is observed. Expand
Injury of the lower ascending reticular activating system in patients with hypoxic–ischemic brain injury: diffusion tensor imaging study
TLDR
Injury of the lower portion of the ARAS was found between the pontine reticular formation and the thalamus in patients with impaired arousal after HI-BI and analysis using DTT is believed to be helpful in the evaluation of patients with impairment of arousal afterHI-BI. Expand
Injury of the ascending reticular activating system by transtentorial herniation in a patient with intracerebral haemorrhage: a diffusion tensor tractography study
TLDR
A 73-year-old female patient was coma mental state when she arrived in the emergency room of a university hospital and was diagnosed with spontaneous ICH in the right frontotemporal lobe, which is a common clinical manifestation of TTH following an intracerebral haemorrhage. Expand
Disconnection of the ascending arousal system in traumatic coma.
TLDR
It is proposed that traumatic coma may be a subcortical disconnection syndrome related to the disconnection of specific brainstem arousal nuclei from the thalamus and basal forebrain. Expand
