Hepatic encephalopathy occurs when the liver can not remove certain toxins and chemicals, such as ammonia, from the blood.1 These toxins and chemicals then build up and enter the brain.1 Hepatic encephalopathy is one of the major complications of cirrhosis (scarring of the liver), and a leading cause of hospital re-admission due to its recurrence, despite treatment.1 It can occur suddenly in people with acute liver failure, but is seen more often in those with chronic liver disease.1 Symptoms of hepatic encephalopathy include mild confusion, forgetfulness, poor concentration and personality or mood changes, but can progress to extreme anxiety, seizures, severe confusion, jumbled and slurred speech and slow movement.1 The first step in treatment is to identify and treat any factors that cause hepatic encephalopathy.2 Once the episode has resolved, further treatment aims to reduce the production and absorption of toxins, such as ammonia.1 Generally, there are two types of medication used to reduce the likelihood of another hepatic encephalopathy episode — lactulose and rifaximin.2 However, it remains a leading cause of hospitalisations and re-hospitalisations in cirrhotic patients, despite the use of the above - mentioned standard of care treatment.

Health improvement (allowing to post - pone / escape the diseases and thus live, healthier / disease - free longer, but not above human MLSP of around 122 years; thus these therapies do not affect epigenetic aging whatsoever, they are degenerative aging problems not regular healthy aging problem (except OncoSENS - only when you Already Have Cancer - which cancer increases epigenetic aging, but cancer removal thus does not change anything / makes no difference about what happens in the other cells / about what happens in the normal epigenetic «aging» course in Normal non-cancerous healthy cells) Although there is not such thing as «healthy aging» all aging in «unhealthy» (as seen from elders who are «healthy enough» who show much damage), it's just «tolerable / liveable» enough (in terms of damage accumulating) that it does not affect their quality of life (enough yet), that is «healthy aging»: ApoptoSENS - Clearing Senescent Cells (this will have great impact to reduce diseases, the largest one, since it's all inflammation fueled by the inflammation secretory phenotype (SASP) of these senescent cells) AmyloSENS - Dissolving the Plaques (this will allow humans to evade Alzheimer's, Parkinsons and general brain degenerescence, allowing quite a boost; making people much more easily reach the big 100 - since the brain is causal to how long we live; keeping brain amyloid - free and keeping our memories / neuron sharp / means longer LongTerm Potentiation - means longer brain function means longer heavy brain mass (gray matter / white matter retention seen in «sharp - witted» Centenarians who show are younger brain for their age), and both are correlated to MLSP).

Sure enough, when the researchers examined the brains of PD patients, they found more cells exhibiting signs of senescence than in people without the disease — and especially astrocytes, as they had expected.7 This was true even after matching patients for age, meaning that PD subjects had even more senescent astrocytes in their SNcs than is typical for people their age (ranging in this case from 50 — 92 years at autopsy)-- and remember, aging already drives an increase in the burden of these cells as compared with young people, even in those who have yet to develop Parkinson's disease.7

Both recent experience with immunotherapy for clearance of Aβ in AD, and their own (and Prothena's) experience with AS - clearing immunotherapies in animal models, indicate that in order to be effective as disease - modifying agents when administered alone, therapies that remove proteinaceous aggregates from the brain must be initiated in the early clinical or even preclinical stages of the disease, before the burden of other forms of aging damage becomes entrenched.
