 Most common motor sign is paratonic rigidity or gegenhalten, a resistance to passive movement of limbs that is velocity-dependent  Asterixis, multifocal myoclonus, seizures and tremor are relatively infrequent  Cranial nerve functions are almost [slideshare.net]

Asterixis can be detected. Stage 2. Lethargy or apathy. Minimal disorientation. Inappropriate behavior. Slurred speech. Obvious asterixis. [clevelandclinicmeded.com]

Grade I Trivial lack of awareness, euphoria or anxiety, shortened attention span, impaired performance of addition or subtraction Grade II Lethargy or apathy, minimal disorientation for time or place, subtle personality change, inappropriate behavior, asterixis [clinicaladvisor.com]

Patients underwent a daily cognitive assessment with the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) test. RESULTS: Twenty-one patients (55%) were found to present confusion. [ncbi.nlm.nih.gov]

 Defined as brain dysfunction due to sepsis and SIRS  Also called sepsis-associated delirium  Clinically, acute impairment in the level of consciousness and confusion (manifested by alteration in attention, disorientation and concentration up to [slideshare.net]

It can range from slight confusion to coma and can be, although rarely, accompanied by focal neurological signs. [scitechnol.com]

This condition can cause mild confusion to deep coma. Wernicke encephalopathy Also known as Wernicke’s disease, this condition is a result of vitamin B-1 deficiency. [healthline.com]

[…] consciousness that consists of three types: Type B: HE associated with portal-systemic bypass without intrinsic hepatocellular damage Type C: HE associated with end-stage liver disease (ESLD) or cirrhosis with portal-systemic shunt HE can range from minimal confusion [clinicaladvisor.com]

"The first manifestation of SAE is an acute change in mental status, ranging from inattention, disorientation, agitation, somnolence, stupor and coma," the authors write. There is no specific treatment for SAE. [news-medical.net]

SAE can also lead to stupor and coma. This is the most common encephalopathy in the ICU. [alvinandassociateslnc.com]

Arousable by loud voice commands, but immediately lapses into stupor without further response. MAP failed to improve with further increase in norepinephrine. CPP 50 despite increase of ventilatory rate in an effort to decrease ICP. [rense.com]

The overall incidence rate ratio (IRR) for seizures among sepsis survivors was about 5, but was higher for those who also had neurologic dysfunction (such as encephalopathy, delirium, coma, or stupor) during their index hospitalization than in those without [mdedge.com]

The main sign of SAE is an altered mental status. Electroencephalography is the more sensitive diagnostic test, and allows the grading of the severity of cerebral dysfunction that is related to outcome. [ncbi.nlm.nih.gov]

SAE is characterized by an altered mental status (AMS) that ranges from delirium to coma, and can lead to long-term cognitive impairment. [clinicaltrials.gov]

Like altered mental status, and unlike lactate, tachypnea does not require a blood test. [emdocs.net]

Neurotoxicity developed 6 days after positive cultures with altered mental status and blood pressure 128/80 mm Hg. [ajnr.org]

Somnolent but can be aroused, unable to perform mental tasks, gross disorientation about time and place, marked confusion, amnesia, occasional fits of rage, present but incomprehensible speech. Stage 4. [clevelandclinicmeded.com]

It has been recently reported that even a single episode of HE is associated with a persistent cognitive defect, suggesting that HE is not a truly reversible condition. [clevelandclinicmeded.com]

EEGs were classified into five groups: normal, excessive theta, predominant delta, triphasic waves, and suppression or burst suppression, in ascending order of severity. [ncbi.nlm.nih.gov]

All recordings were assessed for the presence of burst suppression and a maturition score was assigned. [wakespace.lib.wfu.edu]

Patients with lethal outcome were more likely to be female (p 0.0011), to have focal seizures (p 0.034), lower values of GCS during hospitalization (p CONCLUSION: Presence of focal seizures, EEG suppression at the time of exacerbation in SAE elderly patients [ncbi.nlm.nih.gov]

Both patients showed diffuse brain edema on CT and severe brain dysfunction on electroencephalography within a day of onset. [ncbi.nlm.nih.gov]

These therapies include mild hyperventilation which curtails intracerebral blood volume, ventricular drainage of CSF and osmotherapy to reduce brain edema/parenchymal volume. [pulmccm.org]

Vasogenic Edema Extent of brain edema was compared between patients from groups 1 and 2, and the results are summarized in Table 4. [ajnr.org]

Ammonia is thought to result in both cytotoxic and vasogenic brain edema due to the cerebral energy failure, excessive intracellular accumilation of glutamine and alteration in aquaporin-4 integral membrane proteins. [clinicaladvisor.com]

MRI revealed unilateral subcortical white matter lesions in the right hemisphere. She was diagnosed as having sepsis-associated encephalopathy and was treated with dexamethasone and midazolam. [ncbi.nlm.nih.gov]

Nonspecific white matter lesions are also described in other studies. [6], [7] Finelli and Uphoff reported cases with bilateral basal ganglia, thalamic, cerebellar, brainstem, and cerebral MR abnormalities in sepsis. [8] Furthermore, MR abnormalities [jdrntruhs.org]
