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
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.
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.
Altered mental status is present in up to 23% of patients with sepsis. 7 Mental dysfunction may even precede the cardinal findings of sepsis. 8 When present, SAE is associated with a poor prognosis.
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].
They concluded that septic patients have a high mortality rate after two years of hospital discharge compared to patients recovered from other diseases; the percentage of death ranged from 22% to 70%.
Long term effects of sepsis
Symptoms of post-sepsis syndrome include: feeling lethargic or excessively tired.
When germs get into a person's body, they can cause an infection. If you don't stop that infection, it can cause sepsis. 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.
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.
Most people make a full recovery from sepsis. But it can take time. You might continue to have physical and emotional symptoms. These can last for months, or even years, after you had sepsis.

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.
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.
Sepsis-associated encephalopathy is characterized by acute changes in mental status, cognition, alteration of sleep/wake cycle, disorientation, impaired attention, and/or disorganized thinking [66].
In conclusion, noninvasive assessment by MRI allowed the identification of new aspects of brain damage in sepsis, including cytotoxic and vasogenic edema as well as neuronal damage.
Introduction. Survivors from sepsis have presented with long-term cognitive impairment, including alterations in memory, attention, concentration, and global loss of cognitive function.
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.
Severe sepsis = sepsis associated with organ dysfunction, hypoperfusion, or hypotension. Hypoperfusion and perfusion abnormalities may include, but are not limited to lactic acidosis, oliguria, or an acute alteration in mental status.
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.
As severe sepsis usually involves infection of the bloodstream, the heart is one of the first affected organs.
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.
The condition can arise suddenly and progress quickly, and it's often hard to recognize. Sepsis was once commonly known as “blood poisoning.” It was almost always deadly. Today, even with early treatment, sepsis kills about 1 in 5 affected people.
ANSWER: Sepsis is a serious complication of an infection. It often triggers various symptoms, including high fever, elevated heart rate and fast breathing. If sepsis goes unchecked, it can progress to septic shock — a severe condition that occurs when the body's blood pressure falls and organs shut down.
