The point-prevalence of tardive dyskinesia in schizophrenics from a discrete geographical area (Nithsdale, in Dumfries and Galloway Region) in 1981, 1982, and 1984 was 31%, 27%, and 30% respectively. This suggests that the prevalence of tardive dyskinesia in a community of schizophrenics has reached a plateau. In 12% of patients there was persistent dyskinesia, i.e. abnormal involuntary movements were present at all three assessments. Persistent dyskinesia was more common in older patients. The severity of tardive dyskinesia fluctuated between assessments in 41 % of patients, indicating that it is only a transient feature in some cases.

Of 113 patients in long-stay wards of a psychiatric hospital, 43 had TD. Twenty-six of the 39 patients who consented to take part in the study were unaware of abnormal involuntary movements. These patients scored significantly lower on a short test of cognitive function than patients who were aware of such movements. The diagnosis of schizophrenia, perticularly the ‘defect’ state with cognitive deficit and negative symptoms, was found to be associated with lack of awareness of TD.

Five patients with abnormal involuntary movements of tardive dyskinesia were treated with dihydrogenated ergot alkaloids (Hydergine) in doses of 3 to 4 milligrams a day for six weeks. Blind ratings of standard videotape recordings indicated significant differences between the patients. Worsening occurred in three patients during treatment and to a lesser extent after treatment; improvement during treatment appeared in one patient and more sustained improvement in one patient.

Background: RE-KINECT (NCT03062033), a real-world study of possible tardive dyskinesia (TD) in antipsychotic-treated patients, included a questionnaire to assess the effects of patients’ abnormal involuntary movements on caregivers. Objective: To capture the experiences of caregivers who assisted individuals with abnormal involuntary movements that were confirmed by clinicians as being consistent with TD. Methods: Qualified (nonpaid) caregivers were invited to complete a questionnaire that included the following: caregivers’ sociodemographic characteristics, their perceptions about the impact of abnormal involuntary movements on patients, and the impact of these movements on themselves (caregivers). Results: Of the 41 participating caregivers, 25 (61.0%) were women, 20 (48.8%) were employed full time or part time, and 35 (85.4%) were family members or friends. Based on responses from caregivers who noticed patients’ abnormal involuntary movements and were caring for individuals who also noticed those movements, 48.0% of patients had “a lot” of severity in ≥1 body region and 76.0% had abnormal involuntary movements in ≥2 regions. Caregiver ratings were significantly correlated with patient ratings (but not with clinician ratings) for maximum severity of abnormal involuntary movements and the number of affected regions (both p <.05). Based on their own judgments and perceptions, caregivers reported that the patient’s movements had “some” or “a lot” of impact on their (caregiver’s) ability to continue usual activities (50.0%), be productive (58.3%), socialize (55.6%), or take care of self (50.0%). Conclusion: Caregivers as well as patients are negatively affected by TD, and the impact of TD on caregivers’ lives should be considered when determining treatment options.
