This is an extract from a training video for psychiatrists and medics. It details involuntary abnormal movements. It is worth noting that these movements are all drug induced, primarily by neuroleptic medication (i.e. anti-psychotic medication such as chlorpromazine, stelezine and so forth) and often do not resolve upon cessation of the medication.
These kinds of movements are often associated with "madness", but so few people realise that they are iatrogenic in origin (i.e. induced by the treatment, not the problem being treated) and serve to add immeasurably to the individuals problems.
