After the brain, the heart is the second most sensitive organ to ischemia. [4] If the cause of the cardiac arrest was fundamentally a coronary pathology, then the consequences to the heart may include myocardial infarction complications. However, if the fundamental cause was non-coronary, then the heart becomes ischemic as a consequence, not a ...
In adults, Neisseria meningitidis and Streptococcus pneumoniae together cause 80% of bacterial meningitis cases. Risk of infection with Listeria monocytogenes is increased in people over 50 years old. [3] [8] The introduction of pneumococcal vaccine has lowered rates of pneumococcal meningitis in both children and adults. [28]
Survivors of Haemophilus meningitis may experience permanent damage caused by inflammation around the brain, mostly involving neurological disorders. Long-term complications include brain damage, hearing loss, and mental disability. [5] Other possible long-term effects are reduced IQ, cerebral palsy, and the development of seizures. [10]
Some of the possible symptoms of chronic meningitis (due to any cause) include headache, nausea and vomiting, fever, and visual impairment. Nuchal rigidity (or neck stiffness with discomfort in trying to move the neck), a classic symptom in acute meningitis, was seen in only 45% of cases of chronic meningitis with the sign being even more rare in non-infectious causes.
Meningococcal disease causes life-threatening meningitis and sepsis conditions. In the case of meningitis, bacteria attack the lining between the brain and skull called the meninges. Infected fluid from the meninges then passes into the spinal cord, causing symptoms including stiff neck, fever and rashes.
The causes of brain ischemia vary from sickle cell anemia to congenital heart defects. Symptoms of brain ischemia can include unconsciousness, blindness, problems with coordination, and weakness in the body. Other effects that may result from brain ischemia are stroke, cardiorespiratory arrest, and irreversible brain damage.
Damage to the Broca's area and the Wernicke's area of the brain (left side) typically causes problems with speech and language. Damage to the right side of the brain may interfere with the ability to express emotions or interpret what one sees. Damage on either side can cause paralysis of the opposite side of the body.

Aseptic meningitis is a common condition, which is caused by many viruses but also from autoimmune etiologies. MRS occurs in 8% of aseptic meningitis cases. Average latencies from the onset of meningeal irritation to urinary symptoms were 0–8 days. However, in some cases, urinary retention precedes fever and headache.
