The occurence of extranuchal dystonia, facial spasm, parkinsonian symptoms (facial masking, bradykinesia, rigidity), tremor and family history of tremor was tabulated in a group of 30 patients with IST. The incidence of extranuchal dystonia increased as severity of IST increased. There was a strong trend for severity of extranuchal dystonia to increase as severity of torticollis increased, which was significant (p less than 0.001). There was a similar trend for severity of facial spasm to increase with increasing severity of torticollis (p less than 0.025). Parkinsonian features were seen in 10 of 30 patients, and in three the diagnosis of Parkinson's disease could be entertained. Tremor was seen in 26 of 30 patients being mild in 12, moderate in 11, and severe in three. A family history of tremor was present in 16 of 28 cases for whom history was available (12 primary, four secondary relations). The results are most consistent with the hypothesis that IST is a variant of DMD with tremor as an integral part of the disease and tremor represents a forme of the disease in family members.

Dystonia in the pediatric age group can be confused with hysteria, particularly when it occurs in an emotionally disturbed child with a negative family history of dystonia. A 20-year-old girl with a 12 year history of DMD is described. From age 12 to 17 she was housed in a mental institution after a misdiagnosis of hysteria was made. The progressive nature of DMD and the important emotional components are stressed. The multidisciplinary management model is discussed as a valuable method in the treatment of this chronic neurological disorder.

A prospective long-term semiquantitative evaluation of the results of ventral intermediate-posterior ventral oral nucleus thalamotomy on the different aspects of dystonia was made in 29 patients with secondary disease, 12 with nonfamilial, eight with (non-Jewish) familial, and seven with atypical DMD. The effect of disease progression, even in secondary patients, on surgical outcome was reviewed. Thalamotomy resulted in a long-term improvement in limb function of more than 25% to 50% in 23% of the patients, over 50% in 34% of patients, but midline features responded poorly. Manual dexterity was little changed in secondary cases because of underlying paralysis but improved 38% in cases of DMD. Involvement of neck and trunk, of three to four limbs, and progressive disease prognosticated for a poorer result, but phasic and tonic, familial, and nonfamilial dystonia respond equally well and age at surgery made no difference. Significant complications in 29 secondary cases included one death 31 days postoperative, one case of worsened hemiparesis, two cases of worsened dysarthria, two cases of worsened locomotion, one case of hydrocephalus requiring shunting, and one case of need for permanent tracheotomy. In 27 cases of typical and atypical DMD, there were two instances of hemiparesis, two of significant speech deterioration, three of hand ataxia, one of postoperative seizures, and one of hydrocephalus requiring shunting for an overall significant morbidity rate of 21%. The limiting factor in treating secondary dystonia is the underlying spastic paralysis but that in DMD is the relentless postoperative progression. The overall results of this study are remarkably similar to those of other published series: a quarter of the patients improved by 25% to 50%, a quarter to a third by more than 50%. The analysis of effect on specific features of the disease may be useful in the future for predicting outcome in a particular patient.
