Sepsis causes cerebral dysfunction in the short and long term and induces disruption of the blood–brain barrier (BBB), neuroinflammationNeuroinflammation is inflammation of the nervous tissue. It may be initiated in response to a variety of cues, including infection, traumatic brain injury, toxic metabolites, or autoimmunity.https://en.wikipedia.org › wiki › Neuroinflammation
Sepsis is a potentially life-threatening condition caused by a systemic dysregulated host response to infection. The brain is particularly susceptible to the effects of sepsis with clinical manifestations ranging from mild confusion to a deep comatose state.
Brain dysfunction is a frequent and severe complication of septic shock, as it occurs in up to 60% of patients [1, 2] and is associated with increased mortality [3] and long-term cognitive impairment [4, 5].
However, the severity of SAE parallels the severity of the septic illness and the brain's microcirculation is probably affected in a similar manner to that of other organs. Mild cases of SAE are often completely reversible, but there is increasing evidence that severe cases have neurological sequelae.
Disabling muscle and joint pains. Decreased mental (cognitive) function. Loss of self-esteem and self-belief. Organ dysfunction (kidney failure, lung problems, etc.)
This is known as Post Sepsis Syndrome (PSS) and usually lasts between 6 and 18 months, sometimes longer. Because you may look well, others (including your employer, doctor, or family) may be unaware of the problems and expect you to be better now. Don't suffer in silence.
White matter changes and brain atrophy can be detected using brain imaging, but unfortunately, there is no specific treatment that directly addresses the underlying mechanisms of cognitive impairments in sepsis.
Complications. As sepsis worsens, blood flow to vital organs, such as your brain, heart and kidneys, becomes impaired. Sepsis may cause abnormal blood clotting that results in small clots or burst blood vessels that damage or destroy tissues.
Long term effects of sepsis
Symptoms of post-sepsis syndrome include: feeling lethargic or excessively tired.
And for all ages, the worse the sepsis, the greater the risk of developing dementia. Another study published in 2010 estimates that there may be as many as 20,000 new cases of dementia every year caused by sepsis.
These changes are present in the most severe cases. The parts of the brain mostly involved in sepsis are the frontal cortex and the hippocampus, which leads to cognitive dysfunction [23]. There might be a brainstem dysfunction caused by the passage of inflammatory mediators through area postrema.
Systemic insults, such as prolonged inflammation, severe hypoxemia, and persistent hyperglycemia also may contribute to aggravate sepsis-induced brain dysfunction or injury. The diagnosis of brain dysfunction in sepsis relies essentially on neurological examination and neurological tests, such as EEG and neuroimaging.
Encephalopathy is associated with altered electroencephalographic activity, but less frequently with neuroimaging changes1,2. A complete recovery is possible, while on the other hand, brain death is almost never observed as a direct consequence of sepsis.

Secondary encephalitis.
Instead of attacking only the cells causing the infection, the immune system mistakenly attacks healthy cells in the brain. Also known as post-infection encephalitis, secondary encephalitis often occurs 2 to 3 weeks after the initial infection.
The organs more frequently affected are kidneys, liver, lungs, heart, central nervous system, and hematologic system. This multiple organ failure is the hallmark of sepsis and determines patients' course from infection to recovery or death.
A person with sepsis might have one or more of the following signs or symptoms: High heart rate or weak pulse. Fever, shivering, or feeling very cold. Confusion or disorientation.
These changes in the blood–brain barrier might lead to a major symptom of sepsis, sepsis-associated encephalopathy, which manifests as confusion with a rapid decline in cognitive functions, especially memory, or coma.
Introduction. Survivors from sepsis have presented with long-term cognitive impairment, including alterations in memory, attention, concentration, and global loss of cognitive function.
Bacterial infections cause most cases of sepsis. Sepsis can also be a result of other infections, including viral infections, such as COVID-19 or influenza, or fungal infections.
Septic shock is the most severe level and is diagnosed when your blood pressure drops to dangerous levels.
In severe cases, one or more organ systems fail. In the worst cases, blood pressure drops, the heart weakens, and the patient spirals toward septic shock. Once this happens, multiple organs—lungs, kidneys, liver—may quickly fail, and the patient can die.
Severe breathlessness or sleepiness. It feels like you're going to die or pass out. Skin mottled or discoloured. An extremely high or a very low temperature; repeated vomiting; seizures; and a rash which doesn't fade when you press a glass against it are also possible 'red flags'.
When treatment or medical intervention is missing, sepsis is a leading cause of death, more significant than breast cancer, lung cancer, or heart attack. Research shows that the condition can kill an affected person in as little as 12 hours.
