Functional Weakness is the weakness of the arm or leg because the nervous system is not working properly. It is not caused by damage or disease in the nervous system. Patients with functional weakness experience symptoms of lymphatic weakness that can be paralyzing and frightening as walking or 'heavy' on one side, dropping something or feeling that the limbs do not feel normal or 'part of them'. Functional weakness can also be described as a functional neurological disorder (FNsD), Functional Nerve Disorders (FND) or functional neurological symptoms. If symptoms are caused by a psychological trigger, it may be diagnosed as a 'dissociative motor disorder' or a conversion disorder (CD).
To patients and doctors often look as if there is a stroke or have symptoms of multiple sclerosis. However, unlike this condition, with functional weakness there is no permanent damage to the nervous system which means it can be better or even completely lost.
Diagnosis should usually be made by a consultant neurologist so that other neurological causes can be excluded. Diagnosis should be made on the basis of positive features in history and examination (such as Hoover's sign). It is dangerous to make a diagnosis just because the test is normal. Neurologists usually diagnose wrong about 5% of the time (which is the same for many other conditions.)
The most effective treatment is physiotherapy, but it also helps for patients to understand the diagnosis, and some people may find CBT helps them to overcome the emotions associated with becoming unhealthy. For those with conversion disorders, psychological therapy is the key to their treatment because of emotional or psychological factors that cause their symptoms.
