Brett Lillie 2007 9/3/2009 2 Generally abnormal mvts are exaggerated with anxiety and diminish with sleep. By Dr Brett Lil ie (2009) Next, determine what type of invol. mvt: chorea, dystonia, myoclonus, and tremor. Hence look at rhythm, duration, pattern etc. By Dr Brett Lil ie (2009) By Dr Brett Lil ie (2009) Mvt disorders can be defined as syndromes where there is: an excess excess excess excess of mvt (Hyperkinesia, dyskinesia or abnormal invol. mvts) or a lack lack lack lack of voluntary or automated mvts unrelated to weakness. Hypokinesia ( b amount of mvt), bradykinesia (lack of mvt), Akinesia (loss of mvt) are common themes.

(asynergy, ataxia) c misjudgment of distance (dysmetria), and c the intention tremor. By Dr Brett Lil ie (2009) Myoclonus and many forms of tremors do not appear to be related 1 to pathological disorders of the BG, but often arise in other areas of the CNS, and many myoclonic disorders are associated with disease of the Cb. By Dr Brett Lil ie (2009) By Dr Brett Lil ie (2009) It is unknown which part of the brain is involved with Tics. 9/3/2009 4 By Dr Brett Lil ie (2009) Complex pathways (closed Loop) Eg.
