Explanation

Fatal familial insomnia (FFI) is a rare genetic disorder that affects the brain and leads to severe sleep disturbances. People with this condition find it increasingly hard to sleep and symptoms severely progress

Symptoms and Effects:

  • Sleep Problems: The main symptom is trouble sleeping. As the condition progresses, sleep becomes almost impossible.
  • Cognitive Issues: Individuals may experience confusion, memory loss, and difficulty concentrating.
  • Behavioral Changes: People with FFI might have mood swings and changes in behavior.

Causes:

FFI is caused by a mutation in a specific gene that affects the brain. This genetic change leads to damage in certain parts of the brain, which is why sleep and other functions are affected.

Progression:

The disease usually starts in middle age and gets worse over time. Unfortunately, there is no cure, and it eventually leads to death.

For those experiencing mental health concerns related to FFI or other conditions, support is available at 988lifeline.org.
