Inflammatory Conditions: Meningitis, Encephalitis, Brain Abscesses

A set of vocabulary flashcards covering key terms and their definitions related to inflammatory conditions such as meningitis, encephalitis, and brain abscesses.

Meningitis

An acute inflammation of the meninges surrounding the brain and spinal cord, which can cause severe symptoms and may lead to death.

Bacterial Meningitis

A type of meningitis caused by bacteria, leading to serious symptoms including high fever, headache, and nuchal rigidity.

Pia Mater

Streptococcus Pneumoniae

One of the three primary bacteria responsible for causing bacterial meningitis.

Neisseria Meningitidis

Another major bacterium that can cause bacterial meningitis.

Haemophilus influenzae

Cranial Nerve Irritation

Symptoms resulting from inflammation or pressure on cranial nerves, which can occur in meningitis.

Lumbar Puncture

A medical procedure used to collect cerebrospinal fluid (CSF) for analysis, critical for diagnosing meningitis.

Viral Meningitis

Meningitis caused by viruses such as enteroviruses and mumps, generally less severe than bacterial meningitis.

Supportive Care

Treatment aimed at relieving symptoms and ensuring comfort in patients with conditions like encephalitis and meningitis.

Antibiotic Therapy

Treatment with antibiotics, critical in managing bacterial meningitis.

Seizure Precautions

Preventative measures taken to reduce the risk of seizures in patients with neurological conditions.
