A Functional Neurological Disorder (FND) is a medical condition in which the nervous system and the brain/body struggle to communicate, usually due to an abnormality in how the brain functions. Causes can involve both biological factors, emotional factors, and sociological factors.
Functional Neurologic Disorder (FND) is a complex condition impacting the nervous system, leading to diverse neurological symptoms including muscle weakness, tremors, sensory issues, cognitive challenges, and episodes resembling seizures. Diagnosing and treating FND is intricate, as it arises from disrupted communication or function within the nervous system rather than detectable brain alterations through conventional tests.
FND can coincide with neurological conditions like multiple sclerosis or stroke, which typically have clear structural causes. However, FND can also occur independently.
Functional seizures (FS), also termed psychogenic nonepileptic seizures (PNES) or dissociative seizures (DS), constitute a subtype of FND. These sudden events resemble epileptic seizures but lack underlying abnormal electrical activity. How they develop and form is unclear and an area of active research in the field of neurology and psychiatry..
Common symptoms of FND include:
