Meningitis

Meningitis is inflammation of the lining around the brain and spinal cord and needs urgent assessment when suspected.

It may be caused by an infection, though non-infectious causes exist. The illness can worsen quickly, so a person with concerning symptoms should be assessed urgently rather than waiting to see whether they settle.

Neck stiffness is a very common presentation of meningitis. Fever, headache, light sensitivity, vomiting and seizures are common presentations. A person may also become drowsy, confused, unusually irritable, develop a rash, or have cold hands and feet.

Symptoms do not always arrive together. In babies and young children, poor feeding, a high-pitched cry, unusual sleepiness, a bulging soft spot or limpness can be warning signs. Seek emergency care immediately for a seizure, loss of consciousness, confusion, a rapidly worsening illness or a rash that does not fade under pressure.

Viruses and bacteria are common infectious causes. Bacterial meningitis can be particularly severe and is treated urgently. Fungi and other organisms can cause meningitis in particular circumstances, while some medicines, inflammatory disorders and cancers can cause non-infectious inflammation.

The pace varies with the cause and the individual. Some viral cases improve with supportive care, while bacterial illness can deteriorate over a short period. Recovery may include fatigue, headaches, concentration difficulty, hearing changes or emotional adjustment, and follow-up helps address these needs.

Age, an immune system weakened by illness or treatment, certain long-term conditions, a recent head injury or neurosurgery, and close exposure to some infections can affect risk. These factors are reasons to communicate symptoms early; they do not diagnose meningitis.

Clinicians assess vital signs, mental state, skin, neck and neurological function. Blood tests can look for infection and inflammation. A lumbar puncture may examine fluid from around the spinal cord, while imaging may be used when it is needed to assess the brain safely. Treatment may begin before every result is available.

Care depends on the cause and severity. Hospital treatment may include antimicrobial medicine, fluids, oxygen, seizure treatment and close monitoring. Viral meningitis may need rest, fluids and symptom relief, but the decision belongs to the clinical team after urgent assessment. Do not use leftover antibiotics or delay emergency care.

After discharge, follow the care plan and report new fever, worsening headache, confusion, seizure activity or reduced responsiveness immediately. Arrange support for rest and gradual return to routine. Hearing, balance, mood and concentration concerns can be discussed at follow-up.

Some people recover without ongoing problems, while others need support for hearing, balance, seizures, memory, learning or mood changes. Early recognition of these changes allows referral for rehabilitation, audiology or other specialist care.

Recommended vaccines can protect against selected causes of meningitis. Follow local vaccination advice and seek clinical guidance after close exposure to an infection that may require preventive treatment. Hand hygiene and avoiding shared utensils when unwell can reduce spread of some infections.

Suspected meningitis is an emergency, so contact emergency services or go to an emergency department. A GP can support follow-up after recovery, but should not replace urgent assessment of warning signs.
