250 patients were included, 174 were examined or observed for movement disorder: 120 had no missing data, 54 refused part of the exam. Their mean age was 47, 62% male, 53% black, 26% Hispanic, 17% white.
Medication: First Generation Antipsychotic (FGA) 35 (mean CPZ equivalent dose:1177mg), Second Generation Antipsychotic (SGA) 159 (734mg), both FGA and SGA 56 (1907mg), no antipsychotic 3; anticholinergic or amantidine: FGA 57%, SGA 16%, both FGA and SGA: 50%.
Tardive Dyskinesia: all 23%, FGA 36%, SGA 25%, both 7%
Parkinsonism: all 38%, FGA 43%, SGA 33%, both 34%
Akathisia: all 3%, FGA 0%, SGA 4%, both 3%
Pseudo-akathisia: FGA 11%, SGA 4%, both13%
Dystonia: all 10%, FGA 13%, SGA 11%, both 8%
Intention Tremor: all 16%, FGA 0%, SGA 21%, both 16%
Half of those with Intention Tremor had Parkinsonism, a third had TD and a half were on anti-Parkinson medication.
None of these differences were statistically significant at p = 0.05 though intention tremor did show a trend (p = 0.08). The difference between FGA and SGA only became significant when all movement disorders were added together with those on anticholinergics with no movement disorder.
When compared with rates in similar State Hospitals in the 1970s tardive dyskinesia was now half the rate and Parkinsonism about the same.
