Case Introduction
Martha* is a 60-year-old woman who lives alone. She is currently employed as a sales manager at a large car dealership. Martha is divorced and has strained relationships with her 3 married sons who all live in another state.
Medical and Psychiatric History
Martha has a history of panic attacks and mild anxiety that began when she was in college. She was diagnosed with recurrent depression 15 years ago following her divorce; she has experienced more than 5 lifetime episodes with no hospitalizations. For this depressive episode, she has taken multiple antidepressants as well as an unsuccessful trial of adjunctive lithium. Martha’s depression has been labeled as treatment resistant, and she was switched to treatment with 75 mg/d of venlafaxine, a serotonin-norepinephrine reuptake inhibitor. While on this medication, she has experienced significant residual symptoms such as insomnia, anhedonia, and cognitive difficulties, which have caused problems at work.
After 2 months of taking venlafaxine, you suggested that she begin an adjunctive aerobic exercise. She chose water aerobics, since it could also potentially provide relief for her comorbid rheumatoid arthritis,1 chronic low back pain,2 and fibromyalgia.3

Patient Presentation
Two months have passed since Martha’s last visit, and she is complaining about feeling extremely depressed most days. It has been difficult for her to get up in the morning, and her insomnia, anhedonia, and cognitive difficulties have not improved. Her constant depressed mood has made it hard for her to be motivated at work, and her supervisor has mentioned her decreasing sales quotas. She has no interest in her usual daily activities and has not been attending her water aerobics class regularly.
You discuss the available options with Martha, including their potential adverse effects such as weight gain and tardive dyskinesia (TD). When she asks what TD is, you inform her that involuntary movements may occur after a few months of exposure to antipsychotics. Although first-generation antipsychotics confer the greatest risk of TD, second-generation antipsychotics also confer risk.1 You explain that catching symptoms early is important in order to reverse or treat them. Together, you decide to combine her venlafaxine treatment with quetiapine for 6 weeks.2 You start her dosage of quetiapine at 50 mg/d, which is then titrated to 150 mg/d after 1 week. Due to her age, you decide not to prescribe Martha the maximum dosage.
Given Martha’s treatment history and current symptoms, which assessment should you use to meet her treatment goals going forward?
9-item Patient Health Questionnaire (PHQ-9)
Abnormal Involuntary Movement Scale (AIMS)
Body mass index (BMI) and/or waist circumference measurement

Explanation
The correct answer is e. All of the above
Each of these assessments should be performed before Martha’s treatment is continued.
Guidelines recommend that clinicians regularly monitor patients with a depression rating scale during treatment.1 The use of scales such as the PHQ-9 can provide clinicians with a simple and regular way to monitor patients’ symptoms and progress toward the treatment goals of a robust, sustained remission and full functional recovery.
Since Martha is being started on a second-generation antipsychotic (SGA) for the first time, it is recommended that a baseline assessment of any abnormal movements be conducted. Martha is at a higher risk for developing tardive dyskinesia (TD) due to her advanced age and the fact that she is female.2 The AIMS test is widely recommended for screening for TD.2 Certain steps should be taken when administering the exam to patients, such as: unobtrusively observing patients at rest for signs of potential dyskinesia symptoms, providing a firm chair without arms (or with short arms) so that the patient’s hands may hang unsupported, prompting the patient to remove anything they may have in their mouth (such as gum) and inquiring about any problems with their teeth (such as ill-fitting dentures), and asking about the patient’s awareness of any involuntary movements exist.3
SGAs have a tendency to cause significant weight gain4 or the onset of diabetes in patients (although rare), so performing an initial BMI and/or waist circumference measurement is necessary to recognize weight gain during treatment.5 Additionally, patients with diabetes have a higher risk of developing TD when being treated with SGAs.2
Guidelines for the diagnosis and treatment of insomnia recommend that patients be screened with a tool such as the ESS.6 Guidelines1 for the treatment of depression recommend that patients being treated with an antidepressant who have developed insomnia or other restless behaviors be treated with sleep hygiene techniques or cognitive-behavioral therapy. Other options include adding a sedative-hypnotic medication, trazodone, or melatonin.

Follow-Up Visit
Martha returns after 6 weeks of treatment with venlafaxine and adjunctive quetiapine. She has responded well and her symptoms have improved. You re-administer the assessment tools and schedule a follow-up several weeks later.
At her next follow-up visit, 9 weeks later, Martha complains of uncontrollable movements of her mouth and tongue with some additional involuntary twisting of her shoulders and arms. You administer the AIMS rating scale again, and Martha scores a 2 (indicating mild severity) in both the “Facial and Oral Movements” and “Trunk Movements” categories. Once you have ruled out a diagnosis of spontaneous dyskinesia that sometimes affects the elderly,1 you determine that Martha meets the Schooler-Kane diagnostic criteria for TD.2
Given this new development in Martha’s condition, what is the best next step in her treatment plan?
Lower quetiapine to its original dose of 50 mg/d
Discontinue venlafaxine
Gradually reduce the dose of quetiapine to zero over several weeks
The correct answer is c. Gradually reduce the dose of quetiapine to zero over several weeks
Since Martha has not been diagnosed with schizophrenia and therefore does not need continuing antipsychotic treatment, the best option for her treatment is to discontinue quetiapine immediately using stepwise dose reduction over 2-3 weeks. If TD symptoms are caught early, there is a higher chance that they will remit entirely.1 Additionally, guidelines2 for clinicians treating patients with depression warn about the disadvantages of prescribing a combination of antidepressants and SGAs compared with other antidepressant augmentation strategies.
Considering that quetiapine was not well tolerated and Martha’s unsuccessful response to lithium in the past, other options for her treatment include: switching to a different antidepressant (either within class or across class),2 thyroid augmentation such as liothyronine,3 or consideration of repetitive transcranial magnetic stimulation.2

Follow-up and ConclusionBy 4 weeks after discontinuing her quetiapine, Martha’s TD symptoms have dissipated.
Clinicians should regularly screen patients who are being treated with antipsychotic medications in order to detect potential dyskinesia symptoms early.
For patients who are at a higher risk for developing tardive dyskinesia, clinicians should monitor patients closely and prescribe the lowest recommended dose of antipsychotics.

Statement of Need and Purpose
Some physicians are unaware that tardive dyskinesia (TD) is associated with second-generation antipsychotic (SGA) agents to a greater extent than previously thought. Education about the prevalence and incidence of TD and risk factors and screening tools is needed because SGAs are used to treat multiple illnesses and the older first-generation antipsychotic agents are also still prescribed. Early recognition is key to management of TD, but subtle signs are easily missed if routine standardized screening is not performed. Survey data show that many psychiatrists have not received training on TD, most do not feel competent in using a screening scale, and most do not discuss TD risk with patients before prescribing antipsychotics. Some clinicians continue treatment unchanged after a movement disorder has appeared because patients are responding so positively to the present treatment regimen. Not only does this increase the chances for TD symptoms to become permanent, it can lead to patient nonadherence, which may ultimately lead to relapse. Therefore, education for physicians is also needed about evidence-based treatment options for patients with TD. This activity was designed to meet the needs of participants in CME activities provided by the CME Institute of Physicians Postgraduate Press, Inc., who have requested information on TD.
