        headache, fever, stiff neck, and signs of cerebral dysfunction (confusion, delirium),seizures.
        
        palsies, facial weakness and/or deafness, and vertigo
      - cerebral abscess
  - - - transmitted to neonates during vaginal delivery
    - - healthy and immunocompromised adults.
    - - across the blood-brain barrier, the virus enters the neurons and disrupts cellular functioning, causing bleeding and inflammation
- - - - oxygen supply is decreased
      - Neurons dependent on glucose for production of ATP
      - oxidative phosphorylation impaired
      - Restricts anaerobic production of ATP
      - about 5 to 10 minutes of complete occlusion → brain damage
    - - Mitochondrial failure

        Mitochondrial sequestration of Ca＋
      - calcium overload
