=====Functional Neurological Disorder=====
**Functional Neurological Disorder**
  *one of most common neurological conditions
  *frequently present as dissociative seizures or stroke like presentations
    *nearly 10% of hyper-acute stroke unit admissions are said to be FND
  *Ix does not reveal pathology
  *examination rely on distraction testing techniques:
    *Hoover's sign - hip extension in a patient with unilateral functional weakness is weak when tested directly, but briefly returns to normal when triggered by contralateral hip flexion
    *‘give way’ weakness - full power is generated for a second, but then disappears
    *distractibility, demonstrating a discrepancy between volitional and non-volitional motor function
  *recurrent episodes with normal imaging suggest functional weakness rather than stroke or other neurological disorders
