How Do You Spell ENCEPHALITIS LETHARGICA?

1. Encephalitis Lethargica is a rare neurological disorder characterized by inflammation of the brain, specifically the basal ganglia and midbrain. The condition was first identified in the early 20th century during the global pandemic of Influenza, but the exact cause remains unknown. The condition primarily affects the central nervous system, leading to a range of symptoms including high fever, headache, fatigue, muscle weakness, and various neurological abnormalities.

   Encephalitis Lethargica is often referred to as "sleepy sickness" due to its characteristic symptom of excessive sleepiness or prolonged periods of altered consciousness. However, the condition may also cause symptoms such as movement disorders, including Parkinsonism, as well as psychiatric symptoms like depression, irritability, and psychosis. In severe cases, the disorder can lead to a state of catatonia, where the patient may become immobile and unresponsive.

   The natural course of Encephalitis Lethargica can be unpredictable, with symptoms worsening, improving, or even disappearing temporarily. Some individuals may experience long-term complications, while others may recover spontaneously. Treatment generally focuses on managing symptoms and providing supportive care. Various medications, including antiviral drugs and immunomodulatory therapies, are sometimes prescribed, but their effectiveness remains limited.

   Although Encephalitis Lethargica is a rare disorder, its historical significance lies in the fact that it provided insights into the study of neurology and the understanding of infectious diseases affecting the brain. Further research is warranted to unravel the complex etiology and pathophysiology of this enigmatic condition.

2. Nona, a form occurring epidemically, often apparently in association with influenza, marked by apathy, somnolence, diplopia, and extreme muscular weakness.
