3 ways to categorise tremors

What is the difference between athetoid and choreiform?What are choreoathetoid movements?
1) Snake like writhing vs. typically discrete coarse jerky movement2) a combination of the 2 seen in Huntingtons, Wilsons, tardive dyskinesia, dopamine agonists
Blepharospasm - what is it?
Repeated spasmodic closure of the eye lids - probably localised tardive dyskinesia
How does tardive dystonia differ to tardive dyskinesia?
Movements are less jerky and are more sustained, e.g. Grimmacing for at least several seconds
How do automatisms, stereotyped behaviours and mannerisms differ?
Mannerisms are largely under conscious control. They appear purposeful and are consistent distinctive ways of doing things, e.g. Pirouetting before sitting down.Automisms and stereotypies are both involuntary and apparently purposeless. Automisms occurring in the context of altered conscious level and are not remembered by the patient. They can be simple or complex.Stereotypies are complex involuntary behaviour that occur without conscious impairment. E.g. Rocking in PDD
What are tics?
Tics are recurrent motor activities or vocalisations which are difficult to voluntarily control. Attempts to resist tics are met with increasing psychomotor tension which is relieved when the tic occurs.Associated tic disorder, tourettes, ocd, stimulants
