AbstractIntroductionMIND-TD is a collaboration of healthcare professionals (HCPs) who are committed to raising awareness of tardive dyskinesia (TD), a persistent and potentially disabling movement disorder associated with prolonged exposure to antipsychotics and other dopamine receptor blocking agents. The MIND-TD questionnaire was developed to help HCPs screen for TD and facilitate discussion with patients.MethodsIn August 2020, an expert panel of 13 HCPs (4 psychiatrists, 6 neurologists/movement disorder specialists [MDSs], and 3 advanced practice providers [APPs]) met virtually to discuss potential screening questions for TD. This work was continued by 4 panelists (1 psychiatrist, 2 neurologists/MDSs, and 1 APP) who tested the questions in clinical practice for revision and refinement. The same group also worked with the sponsor to develop 2 additional sections that could be used to elicit more information from patients. The panel recognized the need for a tool that could facilitate telehealth screening for TD, including audio-only interactions. Therefore, practices from speech-language pathologists (eg, diadochokinetics) were used to refine the questionnaire.ResultsPart 1 of the MIND-TD questionnaire includes a yes-or-no question for each of the 4 following topics: presence of extra or unwanted movements (Movement); feelings of embarrassment or self-consciousness (Impact); if anyone else has noticed the movements (Notice); and if movements interfere with everyday routines (Daily Activities). Part 1 can be administered by any trained medical staff, either in person or via telehealth (with video or audio-only). Routine administration is suggested in all patients who meet any of the following criteria: current or prior use of any first- or second-generation antipsychotic; use of an anticholinergic medication in conjunction with a current or past antipsychotic; or current diagnosis of TD. Part 2 of the MIND-TD questionnaire has 2 sections. The first (Thorough Interview) includes 9 items related to physical/functional difficulties (eg, eating, speaking, walking, and gripping objects) and 3 simple instructions for speech difficulties. The second section (Differentiate) includes checklists of characteristic movements for TD and drug-induced parkinsonism, along with an item related to akathisia and suggestions for observing abnormal or involuntary movements. Part 2 should be administered by the treating HCP in patients who have abnormal movements that may be related to TD. Part 2 requires visual observation of the patient, whether in-person or via video.ConclusionsMIND-TD is a screening questionnaire that can facilitate a dialogue between HCPs and patients about the risks, symptoms, and impact of TD. The MIND questions can stand alone and be administered during in-person visits or telehealth visits (video or audio-only). The TD section can be used to gather more information about a patient’s abnormal movements.FundingNeurocrine Biosciences, Inc.
