The neurology ‐ psychiatry interface: variations on a diagnostic theme

Abstract

Despite the panoply of clinical assessment and neuroimaging modalities at the disposal of clinicians today, the diagnosis of neurodegenerative disorders may still prove challenging, particularly in the early stages, because of the subtlety of early changes and/or their overlap with (so‐called) psychiatric disorders. A case illustrating these difficulties is presented, in which long‐term follow‐up proved to be the most important investigation to establish the correct diagnosis.
