FND Awareness Day – April 13

Functional Neurological Disorder (FND) is a condition that disrupts the communication between the brain and body. It occurs when the nervous system doesn’t function as it should, despite both the brain and body being physically intact. The disorder can mimic other conditions, which is why many patients are misdiagnosed. Although its exact cause is still unknown, FND has historically been regarded as a psychological disorder, with physical symptoms believed to stem from suppressed trauma.

Around four to twelve people out of every 100,000 are affected by FND. Biological factors such as early childhood trauma, anxiety, or mistreatment can contribute to its development. Sociological elements, like stressful relationships or life pressures, can also trigger episodes. The symptoms of FND are diverse, affecting the physical, cognitive, and sensory functions of the body. These may include motor problems like limb paralysis, walking difficulties, and slurred speech. Sensory dysfunctions, such as loss of vision or facial numbness, are also common. Patients may experience altered consciousness, blackouts, and seizures. Other frequent symptoms include chronic pain, sleep disturbances, fatigue, and depression. The severity of symptoms can fluctuate, with some individuals experiencing them constantly, while others may have days without symptoms, only to relapse unexpectedly. Physical injuries or other illnesses can sometimes trigger these episodes.
