Successful approaches have included physical therapy, psychotherapy and medications such as antidepressants. We do know that successful treatment plans must be individualized based on clinical features, and that the earlier the diagnosis is made and treatment is started, the greater likelihood of reversal of the symptoms. What treatment is available?ĭespite the frequent occurrence of FMD, there are no standardized treatments and this requires more research. Nevertheless, the disorder is felt to be the result of a complex interaction between psychology and neurology, or, put differently, emotion and brain biology. However, this is not always obvious, to the patient or the physician, nor is a psychological event or stressor even necessary to trigger FMD. In the past, these disorders were referred to as "psychogenic disorders" because in many patients the symptoms were triggered by psychological symptoms or stressors. These disorders are often triggered by an illness, or a physical or emotional event. The precise cause of FMD, as with many neurological diseases, remains unclear, particularly because FMD are not caused by structural brain damage, but a functional change. ![]() The diagnosis of functional movement disorders is generally made by neurologists, not psychiatrists. All testing, including imaging, are normal. The diagnosis is clinical, based or medical history and neurological examination. The symptoms of functional movement disorders are specific and recognizable. Many patients also have primary psychiatric disorders such as anxiety and depression which may not have been previously recognized. Functional disorders can occur in combination with other movement disorders, or independently. The symptoms can also fluctuate in type, location, frequency and severity. The symptoms of functional movement disorders generally come on suddenly and can become severe in a very short time. Tremor or shaking is the most common type of functional movement disorders making up about half the cases, followed by painful spasms and abnormal postures and jerking movements, but the symptoms can manifest in a variety of abnormal movements, even looking like Parkinson's disease or including multiple types in one patient. What are the signs and symptoms of FMD and how is it diagnosed? FMD also have many types such as shaking (or tremor), abnormal muscle spasm and posturing (also referred to as dystonia) and jerky movements (also referred to as myoclonus) and there are others. Functional Movement disorders (FMD) represent a significant portion of functional neurological disorders. FND manifest with symptoms that are typically seen in neurology clinics, for example, seizures-like episodes, weakness, abnormal sensations, pain, walking problems and movement disorders. Instead there is a functional problem (or malfunction) of the brain which is often reversible. With functional neurological disorders, there is no structural damage or degeneration of the nervous system. For example, shaking or tremor that is not typical of Parkinson's disease or essential tremor. Functional Movement Disorders What are Functional Neurological Disorders (FND)?įunctional neurological disorders represent a group of disorders where there are often distressing and disabling neurological signs and symptoms that occur which cannot be accounted for by other known disease entities. ![]()
