Neurological signs of tick-borne diseases (such as TBE, Lyme disease, or Powassan virus) often arise from inflammation of the brain or nervous system, manifesting as severe headaches, confusion, stiff neck, seizures, and altered mental status. Other key symptoms include facial palsy, ataxia, severe fatigue, and, in severe cases, paralysis or coma.

Symptoms can include fever, headache, vomiting, weakness, confusion, loss of coordination, speech difficulties, and seizures.

How to know if an infection is spreading to the brain?

When an infection spreads to the brain, symptoms signal a medical emergency, including severe headache, high fever, stiff neck, confusion, personality changes, seizures, vomiting, and weakness or paralysis on one side of the body, often appearing suddenly and requiring immediate medical attention. These signs indicate inflammation (encephalitis or meningitis) or a collection of pus (brain abscess), affecting brain function, consciousness, and nerve control.

What does neuro inflammation feel like?

Neuroinflammation — an inflammatory response within the brain and spinal cord — is more than a medical buzzword. It is a complex process that can contribute to a wide range of symptoms, from persistent brain fog, fatigue, and mood swings to more severe cognitive or autonomic dysfunction.
