Aivotulehduksia

Aivotulehduksia, known as brain inflammation or encephalitis in medical terminology, refers to the swelling and inflammation of the brain tissue caused by infections, autoimmune responses, or other underlying conditions. It is a serious neurological condition that can develop rapidly and may lead to severe complications, including neurological deficits, coma, or death.

The most common causes of aivotulehduksia are viral infections, such as herpes simplex virus, varicella-zoster virus, enteroviruses, and West Nile virus. Bacterial, fungal, or parasitic infections can also induce brain inflammation, although these are comparatively less frequent. Autoimmune responses, where the immune system mistakenly attacks brain tissue, represent another pathway for inflammation, often seen in conditions like autoimmune encephalitis.

Symptoms of aivotulehduksia can vary but typically include headache, fever, confusion, seizures, sensory or motor deficits, and altered consciousness. Diagnosis involves clinical evaluation, neuroimaging (such as MRI or CT scans), lumbar puncture to analyze cerebrospinal fluid, and laboratory testing to identify causative agents.

Treatment depends on the underlying cause. Antiviral, antibacterial, or antifungal medications are used when infections are identified. In autoimmune cases, corticosteroids or immunosuppressive drugs may be prescribed. Supportive care, including sedation, anticonvulsants, and intensive monitoring, is often necessary to manage symptoms and prevent complications.

Prognosis varies according to the cause, severity, and timeliness of intervention. Early diagnosis and proper treatment are crucial for improving outcomes. Preventative measures include vaccination, good hygiene practices, and avoiding exposure to known infectious sources.

Overall, aivotulehduksia is a critical neurological condition requiring prompt medical attention to minimize the risk of long-term damage or mortality.
