โœฆ Synopsis

Voluntary suppressibility of abnormal movements is helpful in the classification of movement disorders because this ability appears to be a common component of tics. However, there has been no systematic study of voluntary suppressibility in other movement disorders. We have therefore assessed 146 patients with tremors and dyskinetic disorders as to their ability to suppress movements by mental concentration. Patients were videotaped while trying to stop their movements, and the length of time they could suppress their abnormal movements was recorded. One hundred percent (10 of 10) of patients with tics could suppress movements for an average of 2.5 min. Two percent (1 of 50) of essential tremor patients could suppress the tremor, and the tremor of 24% (12 of SO) was made worse by mental concentration. Eighty percent (4 of 5) of neuroleptic-induced tremor could be improved mentally. Seventy percent (35 of 50) of patients with parkinsonian tremor could voluntarily diminish their

Levodopa (L-dopa)-induced dyskinesia (LID) emerge in the majority of PD patients after long-term L-dopa treatment. LID most often coincide with the maximal antiparkinsonian effect of L-dopa (''peak dose or ondyskinesias'') and are mainly choreiform in nature. Though the precise mechanism responsible

Patients with restless legs syndrome (RLS) suffer from involuntary limb movements during the day. We studied these leg movements in 18 idiopathic (n = 8) and uremic (n = 10) patients at rest. Electromyographically measured muscle contractions were preceded by sensory discomfort in all patients. The

In the past, Huntington's disease was diagnosed when movement disturbances were present in concordance with a positive family history. Early motor signs, however, are often not found in a standard neurologic examination, and their expression is variable. Not until later stages of the disease could o
