Terminological exactitude: changing the names of established neurological disorders

This is a quick post to highlight changes and proposed changes to some neurological terms. It is not unusual for such changes to occur every now and then. We have, for example, seen benign intracranial hypertension (BIH) changed to idiopathic intracranial hypertension (IIH), and Hallavorden Spatz disease transformed into pantethonate kinase associated neurodegeneration (PKAN).

One recent important change in neurological terminology, starting tentatively but beginning to take hold, is of nocturnal frontal lobe epilepsy (NFLE) to sleep-related hypermotor epilepsy.

The second is the suggested change from exploding head syndrome to episodic cranial sensory shock. I am not quite sure it will take off, but time will tell!

The third, not too new but surprising non-the-less, is the change from primary dystonia to focal isolated dystonia

Are you aware of any other issues of terminological exactitude? Please leave a comment.
