Functional neurological disorder (FND) may mimic various kinds of neurologic diseases and may coexist with other neurologic disorders. In cases overlapped by FND, it might be challenging to distinguish symptoms induced by FND and those induced by other underlying neurological disorders, especially when patients show no positive signs indicative of FND. Here, we present the case of a patient who was genetically diagnosed with paroxysmal kinesigenic dyskinesia (PKD). However, most of the patient's symptoms were considered to indicate FND. To our knowledge, there are no reports of FND overlapping PKD. This case illustrates the possibility that FND can coexist with and mimic symptoms of other diseases. It is necessary to rule out coexisting FND symptoms that may modify clinical presentations that cannot simply be explained by a recognized neurological disease.
功能性神经障碍（FND）可能会模仿各种神经系统疾病，并且可能与其他神经障碍共存。在FND重叠的病例中，区分FND引起的症状和其他潜在神经系统疾病引起的症状可能具有挑战性，尤其是当患者没有提示FND的阳性体征时。在此，我们报告一例经基因诊断为发作性运动诱发性运动障碍（PKD）的患者。然而，该患者的大多数症状被认为提示FND。据我们所知，尚无FND与PKD重叠的报道。该病例说明了FND可能与其他疾病共存并模仿其症状的可能性。有必要排除可能改变临床表现的共存FND症状，而这些临床表现不能简单地用公认的神经系统疾病来解释。
