Dizziness and brain fog, which Hallett and colleagues propose including, are undoubtedly common symptoms in functional neurological disorder, but they are also among the most common symptoms of all unexplained syndromes. Published by the BMJ Publishing Group Limited. The literature to date highlights heterogeneity in responses to treatment, underscoring that more research is needed to individualize treatments and develop novel interventions. Symptoms can vary in severity and may come and go or be persistent. Typically, this disorder affects your movement or your senses, such as the ability to walk, swallow, see or hear. ![]() Rehabilitative interventions (physical and occupational therapy) are treatments of choice for functional motor symptoms, while psychotherapy is an emerging evidence based treatment across FND subtypes. Signs and symptoms vary, depending on the type of functional neurologic disorder, and may include specific patterns. Patients with an FND experience a wide variety of neurological symptoms, including limb weakness, seizures, numbness and vision problems. Twenty two studies on motor and 27 studies on seizure type symptoms report high specificities of clinical signs (64-100%), and individual signs are reviewed. A functional neurological disorder is diagnosed when a patient has neurological and psychiatric symptoms that can’t be explained by a known neurological disorder or medical disease. Signs and symptoms that affect body movement and function may include: Weakness or paralysis Abnormal movement, such as tremors or difficulty walking Loss of balance Difficulty swallowing or feeling 'a lump in the throat' Seizures or episodes of shaking and apparent loss of consciousness. Functional Neurological Disorder is one of medicines most challenging mysteries and those who suffer from it often have to deal with scepticism and misdiagnosis as well as the very real symptoms. The article focuses on the two most frequently identified subtypes of FND: motor (weakness and/or movement disorders) and seizure type symptoms. This review presents the latest advances in the use of validated rule-in examination signs to guide diagnosis, and the range of therapeutic approaches available to care for patients with FND. Functional neurological disorder (FND) is a medical condition in which patients experience a number of neurological symptoms, such as sensory disturbances, fainting, dizziness, weakness, or movement disorders. An early diagnosis, with subsequent access to evidence based rehabilitative and/or psychological treatments, can promote recovery-albeit not all patients respond to currently available treatments. FND is prevalent, generally affecting young and middle aged adults, and can cause severe disability in some individuals. Multiple sclerosis (MS) and functional neurological disorder (FND) are both diagnostically challenging conditions which can present with similar symptoms. This represents a major step toward destigmatizing the disorder, which was often doubted and deemed untreatable. ![]() Functional neurological disorder (FND), previously regarded as a diagnosis of exclusion, is now a rule-in diagnosis with available treatments.
