Functional movement disorder ( FMD ) is also know as functional neurologic disorderliness , conversion disorders.1FMD is applied to conditions where there are physical symptoms such as tremors , abnormal cause , gait problems , etc . But there is no apparent organic disease found that can be the cause of the symptoms . Since , there is no organic disease found the symptom are though to be due to a psychological term . fundamentally , there is a problem in the function of the body but there is no structural problem in the body and the symptoms can not be relate to any neurological or aesculapian condition . The diagnosing of useable apparent movement upset is arrived after excluding skulk ( fabricating symptoms with an underlying motif ) , even though there is no constituent disease FMD patients are not fabricating symptoms .
What Causes Functional Movement Disorder?
The exact causal agency of Functional movement upset is not known.1Many research studies have already start to observe the risk factors and causes . It is believed that a previous injury or a like symptom in the affected body part might trigger FMD . Usually when you get a symptom it adjudicate ad lib or with medicine , here the symptoms get stuck in a form in the nervous arrangement and then it is mirrored in the neutered brain functioning . When that happens , it conk beyond the patient ’s ascendence . Sometimes the symptom might not in reality be present but the affected role feel as if it is there ; she or he is not lying about it because they really feel that way .
Some of the risk factors or triggering ingredient that enquiry subject have found out that has been present continue the Functional movement disorder are :
former days running apparent motion disorder was thought to be strictly psychological , the effect of a recent or earlier stressful effect might manifest as a physical symptom . This is how the term spiritual rebirth disorder name come . But this can not be apply to all patients who were diagnosed with FMD ; therefore this can not fully explain the cause of FMD . A patient role does not necessarily have to be anxious , low or go through a traumatic puerility event to evolve functional movement disorderliness .
A study done by using a single photon expelling computerized tomography ( SPECT ) to see the head has shown reduce blood rate of flow in the thalamus and in the basal ganglia in affected patients for a short period of time .
Another study done by using Electroencephalography ( EEG ) and MRI to visualize the brain and record the brain activity have shown some unnatural change like increased brain natural action in some areas that is not seen in a healthy individual . Another bailiwick done using Voxel - based morphometry shown increase cortical thickness and grey matter book in working movement disorder patients .
FMD occurs both in children and adult . The exact prevalence of FMD is in children is not available because it ’s hard to diagnose FMD in children , however the preponderance is about 1 - 4 per 100,000 . Weakness , unnatural movements and pseud seizures are the common symptom visualize in children . All historic period grouping children are affected by FMD however it is uncommon in children less than 10 age . The exact prevalence of Functional trend disorder in adults is unknown ; the estimated prevalence is 14 - 22 per 100,000 . It is in reality the 2d commonest neurological reasonableness for an adult to visit the outpatient department , whereas the first being headaches / migraine . It is think to be as vulgar asmultiple sclerosisorParkinson ’s disease . FMD is more vulgar in females than in male person in both children and in adult .
Conclusion
Functional movement disorder ( FMD ) is a consideration where there are physical symptom such as tremor , unnatural social movement , gait problem , etc . But there is no apparent organic disease ( structural freakishness ) found that can be the drive for the symptoms . The exact cause of FMD is not known . Many research studies have already start to chance the risk factors and crusade . It is believed that a former injury , continuing pain , emphasis , infection , traumatic effect , panic attacks and physical hurt might actuate usable movement disorderliness . tomography studies done on FMD patient have shown some changes in the brain therefore , there might be a structural variety stimulate FMD .
