İNGİLİZCE ÖZET

Functional movement disorders (FMD) are abnormal involuntary
movements that are not attributable to known neurological and
neuroanatomical causes. In the past decade, FMD diagnoses have
been based on positive factors that are inconsistent with neurological
disorders and not on the exclusion of neurological disorders. In
this report, we presented the case of a female patient who had been
followed up for 4 years in multiple health centers with the diagnosis
of a neurological disorder which was suspected in the previous 1 year
to be of psychogenic origin. A neurological disorder comorbid with
depression and FMD was diagnosed after admission as an inpatient to
our clinic. By presenting this case, it was intended to emphasise the
importance of follow up after diagnosing FMD, given its common basis
with Parkinson’s disease and the high incidence of comorbidites seen
with it. Imaging and elecrophysiological techniques should be relied
upon.for differentiating FMD and neurological diseases. Although
psychological causes are significant disease risk and/or maintenance
factors, they are not sufficient for explaining the aetiology of FMD,
which requires a multidisciplinary approach.
