Meningitis is an inflammation of the membranes (meninges) surrounding the brain and spinal cord. The swelling from meningitis typically triggers symptoms such as headache, fever, and a stiff neck. Most of meningitis is caused by viral infection, but bacterial and fungal infections are other causes. Some others can be life-threatening and require emergent antibiotic treatment.
Patho-physiology of Meningitis:
The brain is of course shielded from the body’s system by the barrier that the tissue layer produce between the blood and therefore the brain. Normally, the barrier prevents the system from assaultive the brain. However, in infectious disease, the barrier will become disrupted; once bacterium or alternative organisms have found their thanks to the brain. Most cases of infectious disease ar caused by associate degree infective agent that has settled or established within the skin, cavity, tract, canal (GI) tract, and therefore the reproductive organ tract. The organism invades the connective tissue at these sites by circumventing host defenses (eg, physical barriers, native immunity, and phagocytes or macrophages).
An irresistible operator (ie, a bacterium, infection, growth, or parasite) can access the CNS and cause meningeal ailment by means of any of the 3 following major pathways:
• Invasion of the circulatory system (ie, bacteremia, viremia, fungemia, or parasitemia) and ensuing hematogenous seeding of the CNS.
• A retrograde neuronal (eg, olfactory and fringe nerves) pathway (eg,Naegleria fowleri and so on).
• Direct adjacent spread (eg, sinusitis, otitis media, inborn deformities, injury, or direct vaccination amid intracranial control).
At the point when the body attempts to battle the disease, the issue can exacerbate; veins wind up defective and permit liquid, WBCs, and other contamination battling particles to enter the meninges and cerebrum. This procedure, thusly, causes cerebrum swelling and can in the long run bring about diminishing blood stream to parts of the mind, intensifying the indications of disease.
Indications:
Meningitis began with a flu signs. Indications may make in excess of a couple of hours or over two or three days. Possible signs and indications in anyone more prepared than the age of 2 include: Sudden high fever, Firm neck, Serious headache that has all the earmarks of being not the equivalent as would be normal, Migraine with nausea or hurling, Perplexity or inconvenience concentrating, Seizures, Sluggishness or inconvenience waking, Affectability to light, Skin rash (all over, for instance, in meningococcal meningitis), A protuberance in the shortcoming over a baby’s head (fontanel).
Two physically certifiable manifestations of meningitis are;
• Kernig’s sign; Severe firmness of the hamstrings makes a powerlessness rectify the leg when the hip is flexed to 90 degrees.
• Brudzinski’s sign; Severe neck firmness makes a patient’s hips and knees flex when the neck is flexed.
Types of meningitis and its treatment:

Infections, for example, Herpes simplex infection, HIV and others likewise can cause viral meningitis.
• The condition happens for the most part in kids or youthful grown-ups, with fractiousness and meningism.
• In viral meningitis, the cerebral pain is normally the most serious element in addition to on and off pyrexia.
Medication OF CHOICE:
• Lessen Fever and diminish Body aches (Acetaminophene 325-650 mg PR q4-6hr PRN)
• Lessen Swelling in the brain (Corticosteroids (Dexamethasone 0.15 mg/kg IV 4 times for 2-4 days)
• To control Seizures (Phenytoin 5 mg/kg/day in 2-3 isolated dosages)
• On the off chance that a herpes infection caused the meningitis, an antiviral solution is accessible. ‘ACYCLOVIR’ ADULT DOSE 400mg Q8 H (7 – 10 days)
NEONATE DOSE 10-20 mg Q8H 14days
Bacterial meningitis:
It happens when microscopic organisms enter the circulatory system, travel to the cerebrum and spinal string causes intense bacterial meningitis. In any case, it can likewise happen when microscopic organisms specifically attack the meninges. Bacterial meningitis has turned out to be less normal however mortality and bleakness stay noteworthy. A few strains of microorganisms can cause intense bacterial meningitis, generally usually:
• Streptococcus pneumoniae (pneumococcus) most basic in babies, youthful youngsters and grown-ups.
• Neisseria meningitidis (meningococcus) exceptionally infectious disease that influences principally youngsters and youthful grown-ups.
• Haemophilus influenzae (haemophilus). Haemophilus influenzae type b (Hib) bacterium was previously the main source in youngsters.
• Listeria monocytogenes (listeria) can cross the placental obstruction, and contaminations in late pregnancy might be lethal to the child. Basic in Pregnant ladies, infants, more seasoned grown-ups and individuals with debilitated invulnerable frameworks are generally vulnerable.

Tuberculosis/chronic meningitis:
The standard source is a caseous concentration in the meninges or mind. Moderate developing life form Mycobacterium tuberculosis attack the films and liquid encompassing the mind cause perpetual meningitis. It creates more than about fourteen days or more. Side effects are cerebral pains, fever, heaving and mental darkness. It is remarkable in solid individuals in created nations yet stays basic in creating nations. It happens in specific advances;

Additional measurements are proposed for youths between the ages of 2 and 5 who are at high threat of pneumococcal ailment, including kids who have interminable heart or lung disease or harm.
• Pneumococcal polysaccharide inoculation (PPSV23). More settled youths and adults who require protection from pneumococcal tiny living beings may get this counter acting agent. The Centers for Disease Control and Prevention endorses the PPSV23 immune response for all adults more prepared than 65; for more energetic adults and youths age 2 and more prepared who have delicate safe structures or steady ailments, for instance, coronary ailment, diabetes or sickle cell press insufficiency; and for any person who doesn’t have a spleen.
Diagnosis:
SPINAL TAP (Lumbar Puncture): A spinal tap is prescribed to gather cerebrospinal liquid (CSF) for a complete finding of meningitis. The CSF frequently demonstrates a low sugar (glucose) level alongside an expanded white platelet check and expanded protein.
