The difficult patient: prevalence, psychopathology, and functional impairment.

OBJECTIVE: To determine the proportion of primary care patients who are experienced by their physicians as "difficult," and to assess the association of difficulty with physical and mental disorders, functional impairment, health care utilization, and satisfaction with medical care. DESIGN: Survey. SETTING: Four primary care clinics. PATIENTS: Six-hundred twenty-seven adult patients. MEASUREMENTS: Physician perception of difficulty (Difficult Doctor-Patient Relationship Questionnaire), mental disorders and symptoms (Primary Care Evaluation of Mental Disorders, [PRIME-MDI]), functional status (Medical Outcomes Study Short-Form Health Survey [SF-20]), utilization of and satisfaction with medical care by patient self-report. RESULTS: Physicians rated 96 (15%) of their 627 patients as difficult (site range 11-20%). Difficult patients were much more likely than not-difficult patients to have a mental disorder (67% vs 35% [corrected], p < .0001). Six psychiatric disorders had particularly strong associations with difficulty: multisomatoform disorder (odds ratio [OR] = 12.3. 95% confidence interval [CI] = 5.9-26.8), panic disorder (OR = 6.9, 95% CI = 2.6-18.1), dysthymia (OR = 4.2, 95% CI = 2.0-8.7), generalized anxiety (OR = 3.4, 95% CI = 1.7-7.1), major depressive disorder (OR = 3.0, 95% CI = 1.8-5.3), and probable alcohol abuse or dependence (OR = 2.6, 95% CI = 1.01-6.7). Compared with not-difficult patients, difficult patients had more functional impairment, higher health care utilization, and lower satisfaction with care, whereas demographic characteristics and physical illnesses were not associated with difficulty. The presence of mental disorders accounted for a substantial proportion of the excess functional impairment and dissatisfaction in difficult patients. CONCLUSIONS: Difficult patients are prevalent in primary care settings and have more psychiatric disorders, functional impairment, health care utilization, and dissatisfaction with care. Future studies are needed to determine whether improved diagnosis and management of mental disorders in difficult patients could diminish their excess disability, health care costs, and dissatisfaction with medical care, as well as the physicians experience of difficulty.

Gender, quality of life, and mental disorders in primary care: results from the PRIME-MD 1000 study.

BACKGROUND: Recently there has been increased interest in the special mental health needs of women. We used data from the PRIME-MD 1000 study to assess gender differences in the frequency of mental disorders in primary care settings, and to explore the potential impact of these differences on health-related quality of life (HRQL). SUBJECTS AND METHODS: One thousand primary care patients (559 women) were interviewed during the PRIME-MD study, which was conducted at four primary care clinics affiliated with university hospitals throughout the eastern United States. Patients completed a one-page questionnaire in the waiting room prior to being seen by the physician; patients and physicians then completed together a clinician evaluation guide that used DSM-III-R algorithms to diagnose mood, anxiety, somatoform, eating, and alcohol related disorders. Health-related quality of life was assessed with the Medical Outcomes Study SF-20 General Health Survey. RESULTS: Women were more likely than men to have at least one mental disorder (43% versus 33%, P < 0.05). Higher rates were particularly prominent for mood disorders (31% of women versus 19% of men, odds ratio [OR] = 1.9, 95% confidence interval [CI] 1.4 to 2.6), anxiety disorders (22% versus 13%, OR = 1.9, CI = 1.3 to 2.8), and somatoform disorders (18% versus 9%, OR = 2.2, CI = 1.5 to 3.4). Psychiatric comorbidity was also more common in women (26% of women had two or more mental disorders versus 15% of men, P < 0.05). Unadjusted HRQL scores, ranging from 0 to 100, with 100 = best health, were all significantly lower in women than in men (eg, physical function = 67 in women versus 76 in men, P < 0.0001; mental health = 69 in women versus 76 in men, P < 0.0001). Many HRQL differences persisted after controlling for age, education, ethnicity, marital status, and number of physical disorders; however, differences in HRQL were eliminated in 5 of 6 domains after controlling for number of mental disorders. When compared with female patients of male physicians, female patients of female physicians demonstrated similar satisfaction with care, health care utilization, HRQL, and recognition rate of mental disorders. CONCLUSIONS: In the 1,000 patients of the PRIME-MD study, mood, anxiety, and somatoform disorders and psychiatric comorbidity were all significantly more common in women than men. The HRQL scores were poorer in women than men, although most of this difference was accounted for by the difference in prevalence of mental disorders. These data suggest that one of the most important aspects of a primary care physician's care of female patients is to screen for and treat common mental disorders.

Health-related quality of life in primary care patients with mental disorders. Results from the PRIME-MD 1000 Study.

OBJECTIVE: To determine if different mental disorders commonly seen in primary care are uniquely associated with distinctive patterns of impairment in the components of health-related quality of life (HRQL) and how this compares with the impairment seen in common medical disorders. DESIGN: Survey. SETTING: Four primary care clinics. SUBJECTS: A total of 1000 adult patients (369 selected by convenience and 631 selected by site-specific methods to avoid sampling bias) assessed by 31 primary care physicians using PRIME-MD (Primary Care Evaluation of Mental Disorders) to make diagnoses of mood, anxiety, alcohol, somatoform, and eating disorders. MAIN OUTCOME MEASURES: The six scales of the Short-Form General Health Survey and self-reported disability days, adjusting for demographic variables as well as psychiatric and medical comorbidity. RESULTS: Mood, anxiety, somatoform, and eating disorders were associated with substantial impairment in HRQL. Impairment was also present in patients who only had subthreshold mental disorder diagnoses, such as minor depression and anxiety disorder not otherwise specified. Mental disorders, particularly mood disorders, accounted for considerably more of the impairment on all domains of HRQL than did common medical disorders. Finally, we found marked differences in the pattern of impairment among different groups of mental disorders just as others have reported unique patterns associated with different medical disorders. Whereas mood disorders had a pervasive effect on all domains of HRQL, anxiety, somatoform, and eating disorders affected only selected domains. CONCLUSIONS: Mental disorders commonly seen in primary care are not only associated with more impairment in HRQL than common medical disorders, but also have distinct patterns of impairment. Primary care directed at improving HRQL needs to focus on the recognition and treatment of common mental disorders. Outcomes studies of mental disorders in both primary care and psychiatric settings should include multidimensional measures of HRQL.

Morning report. A survey of resident attitudes.

BACKGROUND: Morning report is a time-honored tradition of most internal medicine residency programs. Despite its ubiquity, residents' attitudes regarding morning report have not been investigated. METHODS: Using a 44-item questionnaire, we surveyed residents in an academic internal medicine training program working in five teaching hospitals on the processes of teaching and learning during morning report. RESULTS: Among 74 residents completing the survey (100%), morning report was ranked as the most valuable of six educational activities. Residents preferred discussing new cases, with time equally divided between "great" cases and common problems, an interactive discussion with open-ended questions, and a Socratic teaching style. Seventy-two percent stated that attending physicians should be chosen from among the best teachers. General medical knowledge (90%), an ability to ask effective questions (86%), and good interpersonal skills (84%) were identified as the most important attending physicians' attributes. Discussions of basic science, use of anecdotes, and subspecialty knowledge were not considered highly desirable characteristics. Attending physicians with limited knowledge (41%) were viewed as the major obstacle to effective teaching while provocative attending physicians (52%) were considered as being most valuable to the learning experience. CONCLUSIONS: Residents believed that the morning report was a valuable educational experience. They preferred clinically based, open-ended interactive discussions led by attending physicians with a broad knowledge base. These findings underscore the importance of morning report in general, and the role of attending physicians in particular, in medical education.

When the physician leaves the patient: predictors of satisfaction with the transfer of care in a primary care clinic.

OBJECTIVE: To identify independent predictors of patients' satisfaction with transfer of their care from a departing to a new resident physician. DESIGN: A self-administered questionnaire completed by consecutive patients following up after transfer of their care, and by a randomly selected 50% of patients not returning within three months after transfer. SETTING: An internal medicine clinic in a teaching hospital. PATIENTS: Questionnaires were completed by 376 patients: 237 returning to clinic and 139 (91%) of 152 randomly selected patients who had not returned. Mean age of the patients was 65 years, 52% were men, and they had come to the clinic for a median of four years. RESULTS: 57% of the patients were satisfied with the transfer process, 25% were neutral, and 18% expressed frank dissatisfaction. Of nine variables significantly associated with satisfaction by univariate analysis, stepwise multiple regression identified five independent predictors. Personal notification of the patient by the departing physician was the most powerful determinant, explaining 41% of the variability in satisfaction. Other predictors were whether patients believed their physicians had done everything possible to facilitate transfer, whether the departing physician had provided opportunity for discussion of the transfer, whether this discussion was considered sufficient, and patients' impressions of the institution. CONCLUSIONS: Most of the predictors identified can be influenced by physician behavior, suggesting that physicians should personally notify patients of their departure and provide an opportunity for discussion. This could significantly improve patient satisfaction with the transfer process and, as previous studies suggest, translate into greater compliance with medications and follow-up.

Gender differences in depression in primary care.

OBJECTIVES: To determine gender differences in the frequency and manifestation of depression in primary care. STUDY DESIGN: PRIME-MD, a new assessment tool, was tested in 1000 patients as an aid to diagnose depression in primary care patients. Answers to a self-assessment questionnaire completed by patients determined whether physicians administered the mood module in the Clinician Evaluation Guide to diagnose depression. Functional status was assessed with the Medical Outcomes Study Short Form (SF-20). RESULTS: More women than men were diagnosed as having a mood disorder (31% vs 19%; p < 0.01), and an antidepressant was newly prescribed only for women (p < 0.001). There were no gender differences in physician ratings of patients' health, but women rated their health significantly more poorly than did men. Similarly, functional impairment scores were significantly lower in women than in men. CONCLUSIONS: Women are much more likely than men to have depressive disorders, and when these disorders are diagnosed, to receive a prescription for antidepressant medication. Further research is needed to determine why women seem to suffer disproportionately from symptoms of depression and signs of functional impairment.

Psychiatric comorbidity, health status, and functional impairment associated with alcohol abuse and dependence in primary care patients: findings of the PRIME MD-1000 study.

The psychiatric comorbidity, health, and functioning of primary care patients with alcohol abuse and dependence (AAD) were investigated in a sample of 1,000 patients. Psychiatric symptomatology was assessed with the Primary Care Evaluation of Mental Disorders (PRIME-MD) diagnostic system. Health and functional status was assessed with the Medical Outcomes Study Short Form General Health Survey (SF-20). Results indicated that use of the PRIME-MD system brought about a 71% increase in physician recognition of AAD. AAD patients were diagnosed with substantial psychiatric comorbidity, and they reported poorer health and functioning than did patients without any psychiatric disorders. However, they reported less impairment and psychiatric comorbidity than did patients with other psychiatric disorders. Results also indicated that AAD patients' health and functioning were associated with the presence or absence of psychiatric comorbidity.

Utility of a new procedure for diagnosing mental disorders in primary care. The PRIME-MD 1000 study.

OBJECTIVE: To assess the validity and utility of PRIME-MD (Primary Care Evaluation of Mental Disorders), a new rapid procedure for diagnosing mental disorders by primary care physicians. DESIGN: Survey; criterion standard. SETTING: Four primary care clinics. SUBJECTS: A total of 1000 adult patients (369 selected by convenience and 631 selected by site-specific methods to avoid sampling bias) assessed by 31 primary care physicians. MAIN OUTCOME MEASURES: PRIME-MD diagnoses, independent diagnoses made by mental health professionals, functional status measures (Short-Form General Health Survey), disability days, health care utilization, and treatment/referral decisions. RESULTS: Twenty-six percent of the patients had a PRIME-MD diagnosis that met full criteria for a specific disorder according to the Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition. The average time required of the primary care physician to complete the PRIME-MD evaluation was 8.4 minutes. There was good agreement between PRIME-MD diagnoses and those of independent mental health professionals (for the diagnosis of any PRIME-MD disorder, kappa = 0.71; overall accuracy rate = 88%). Patients with PRIME-MD diagnoses had lower functioning, more disability days, and higher rates of health care utilization than did patients without PRIME-MD diagnoses (for all measures, P < .005). Nearly half (48%) of 287 patients with a PRIME-MD diagnosis who were somewhat or fairly well-known to their physicians had not been recognized to have that diagnosis before the PRIME-MD evaluation. A new treatment or referral was initiated for 62% of the 125 patients with a PRIME-MD diagnosis who were not already being treated. CONCLUSION: PRIME-MD appears to be a useful tool for identifying mental disorders in primary care practice and research.

Third-year medical student attitudes toward internal medicine.

BACKGROUND: Student attitudes offer insight into career decisions and may suggest causes of the diminished interest in internal medicine. Students entering a salaried managed health care environment may have different attitudes about careers and potential income. Additionally, we evaluate the effect of an ambulatory experience on student attitudes and career selection. METHODS: We surveyed 163 medical students from the Uniformed Services University of the Health Sciences, Bethesda, Md, at the successful completion of the third year to determine their attitudes regarding the work, lifestyle, prestige, patient type, and challenge of internal medicine, as well as primary care interest, and the importance of income in career selection. A subgroup of 107 volunteers was randomized to either the traditional internal medicine clerkship (n = 69), or to 6 weeks of ambulatory medicine and 6 weeks of ward medicine (n = 38). RESULTS: The selection rate was low for internal medicine (10%) and was high for family practice and transitional internships (37%). Although most students highly valued their internal medicine training, relatively few selected internal medicine as a career. Students saw chronic illness and type of work, but not lifestyle, as disincentives toward choosing an internal medicine career. Half of the students believed that income potential would be a major factor in attracting students into internal medicine, and that reimbursement should be shifted from procedural fields to primary care. The ambulatory clerkship did not affect student attitudes nor type of internship selected. CONCLUSIONS: Medicine clerkships, whether traditional or ambulatory, are highly valued educational experiences yet may be insufficient by themselves to attract students to an internal medicine career. Income potential remains an important concern in the setting of salaried managed care, even for students who lack financial debt.

Physical symptoms in primary care. Predictors of psychiatric disorders and functional impairment.

OBJECTIVE: To examine how the type and number of physical symptoms reported by primary care patients are related to psychiatric disorders and functional impairment. DESIGN: Outpatient mental health survey. SETTING: Four primary care clinics. PATIENTS: One thousand adult clinic patients, of whom 631 were selected randomly or consecutively and 369 by convenience. MAIN OUTCOME MEASURES: Psychiatric disorders as determined by the Primary Care Evaluation of Mental Disorders procedure; the presence or absence of 15 common physical symptoms and whether symptoms were somatoform (ie, lacked an adequate physical explanation); and functional status as determined by the Medical Outcomes Study Short-form General Health Survey. RESULTS: Each of the 15 common symptoms was frequently somatoform (range, 16% to 33%). The presence of any physical symptom increased the likelihood of a diagnosis of a mood or anxiety disorder by at least twofold to three-fold, and somatoform symptoms had a particularly strong association with psychiatric disorders. The likelihood of a psychiatric disorder increased dramatically with increasing numbers of physical symptoms. The prevalence of a mood disorder in patients with 0 to 1, 2 to 3, 4 to 5, 6 to 8, and 9 or more symptoms was 2%, 12%, 23%, 44%, and 60%, respectively, and the prevalence of an anxiety disorder was 1%, 7%, 13%, 30%, and 48%, respectively. Finally, each physical symptom was associated with significant functional impairment; indeed, the number of physical symptoms was a powerful correlate of functional status. CONCLUSIONS: The number of physical symptoms is highly predictive for psychiatric disorders and functional impairment. Multiple or unexplained symptoms may signify a potentially treatable mood or anxiety disorder.

One-year outcome for patients with a chief complaint of dizziness.

UNLABELLED: OBJECTIVE. To determine the one-year outcome for patients with a chief complaint of dizziness that had persisted at least two weeks. DESIGN: Prospective cohort study. SETTING: Federal teaching hospital. PATIENTS: 100 dizzy patients and 25 control subjects. MEASUREMENTS: The primary outcome was dizziness status (improved or not improved); the secondary outcomes were morbidity and health care utilization. RESULTS: The dizziness resolved for 18 patients, whereas the status improved for 37, stayed the same for 32, and worsened for 11, with two patients lost to follow-up. Thus, 55% of patients whose dizziness had not resolved two weeks after their initial visits improved over the subsequent 12 months. Logistic regression revealed four independent predictors of persistent dizziness at one-year follow-up: dizziness due to psychiatric causes, dysequilibrium, vertigo other than benign positional vertigo, vestibular neuronitis, or migraine (odds ratio, 6.3; 95% CI, 2.1-18.6); daily dizziness (odds ratio, 6.4; 95% CI, 2.0-21.0); dizziness worse with walking (odds ratio, 3.0; 95% CI, 1.1-9.0); and patient had initially feared a serious illness (odds ratio, 0.25; 95% CI, 0.10-0.74). These four factors could be used to classify patients as having either a high (82%), medium (47%), or low (0%) likelihood of improvement at one-year follow-up. One patient died from heart failure, and none developed a serious disease for which dizziness had been a harbinger. Dizziness was not associated with an increased number of clinic visits. CONCLUSIONS: Among patients with a chief complaint of dizziness who are still symptomatic at two-week follow-up, more than half improve within a year. Clinical factors identify patients at higher risk for persistent dizziness.

A controlled trial of a seminar to improve medical student attitudes toward, knowledge about, and use of the medical literature.

OBJECTIVE: To determine whether an interactive seminar could affect medical student knowledge of research design, basic critical appraisal skills, and attitudes toward and clinical use of the medical literature. DESIGN: Controlled, nonrandomized clinical trial. PARTICIPANTS: Third-year clinical clerks (n = 146) during their core medicine clerkship. INTERVENTIONS: Two 90-minute interactive seminars. MEASUREMENTS AND MAIN RESULTS: Pre- and postquestionnaires were used to assess knowledge and attitudes regarding the use of the medical literature among 65 study and 81 control students. Blinded review of write-ups assessed actual use of the medical literature. Overall, 80% of the students subscribed to one or more journals and reported reading three or more journal articles per month. After the intervention, the study students were more likely than the control students to consider: 1) study design important in article selection and 2) use of medical literature critical to patient care decisions. Knowledge scores were significantly improved in the study group (p = 0.0001). The intervention yielded no increase in the actual use of medical literature in patient write-ups over that encouraged by usual clerkship goals. 51% of the study and 48% of the control students cited literature at baseline, and 53% of all the students did so after the intervention. Of these citations, 50% were for journal articles and the remainder were for textbooks. The students infrequently mentioned the quality of the cited literature. CONCLUSIONS: An interactive seminar designed to introduce medical students to critical appraisal improved student knowledge and attitudes but did not increase the actual use of literature in patient write-ups.

Mental health services in Army primary care: the need for a collaborative health care agenda.

Epidemiologic studies have shown that more than half of mentally ill patients in the United States receive their psychiatric care exclusively in primary care settings. This fraction may be even higher in the military due to concern over possible occupational repercussions resulting from use of specialty psychiatric care and specialist shortages. Collaboration between generalists and mental health care specialists could potentially improve mental health care delivery and reduce psychiatric disability for a large segment of the Army population who have a psychiatric disorder but may not seek specialty care. Collaborative efforts can reinforce military generalists' essential gate-keeping function, thereby decreasing unnecessary medical utilization and health care costs. The authors review the problems associated with mental health care delivery in primary care and provide examples of collaborative models previously studied or currently being explored. A four-part Army Primary Care-Mental Health Services Agenda is proposed, consisting of: (1) coordinated research including primary care-mental health services research and community-based epidemiologic studies; (2) formation of a primary care-mental health services advisory committee for aiding with policy and program development; (3) graduate and continuing medical education in primary care-mental health services emphasizing interdisciplinary collaborative skills; and (4) clinical implementation of feasible collaborative interdisciplinary mental health care models adapted to the range of unique Army primary care settings. The main goal of the Army Primary Care-Mental Health Services Agenda is to improve access to Army mental health care in the most efficacious and cost-effective way and to help minimize the organizational impact of disability related to psychosocial distress.

Symptoms in the community. Prevalence, classification, and psychiatric comorbidity.

BACKGROUND: While physical symptoms are the leading reason for outpatient visits, a substantial proportion of physical complaints and "minor" illnesses remain poorly understood. The purpose of our study was to determine the prevalence, patient-attributed cause, and psychiatric comorbidity of symptoms in a general population. METHODS: We analyzed data on 13,538 individuals interviewed in the Epidemiologic Catchment Area Program, a multicommunity mental health survey that used the Diagnostic Interview Schedule to determine the prevalence of psychiatric disorders. The Diagnostic Interview Schedule inquires about 38 physical symptoms and includes a probing scheme to classify symptom severity and potential cause. We focused on 26 symptoms most germane to primary care. RESULTS: Of the 26 symptoms, 24 had been problems for more than 10% of persons at some point in their life, with the most common nonmenstrual symptoms being joint pains (36.7%), back pain (31.5%), headaches (24.9%), chest pain (24.6%), arm or leg pain (24.3%), abdominal pain (23.6%), fatigue (23.6%), and dizziness (23.2%). Most symptoms (84%) were at some point considered major in that they interfered with routine activities or had led individuals to take medications or visit a physician. Nearly one third of symptoms were either psychiatric or unexplained, and most symptoms were associated with at least a twofold increased lifetime risk of a common psychiatric disorder. CONCLUSION: Symptoms in the community are prevalent as well as bothersome. Often lacking an apparent physical explanation, such symptoms are associated with an increased likelihood of psychiatric disorders.

Evaluating chest pain. The patient's presentation style alters the physician's diagnostic approach.

BACKGROUND: Clinical prediction rules rely largely on objective data to estimate coronary artery disease (CAD) likelihood. However, characterization of chest pain, which is central to such prediction rules, depends in part on a physician's subjective judgments. We performed a clinical trial to assess the influence of the patient's presentation style on the physician's approach to evaluating chest pain. METHODS: Forty-four internists were randomized to one of three treatment groups. Two groups viewed videotapes of the same actress performing the role of a patient in a scripted physician-patient interview in two distinct styles: one group saw a "histrionic" characterization, the other a "businesslike" portrayal. The interviewer was not seen or heard by the subjects; they saw only words on the screen. The third group read a verbatim transcript of the interview. After their initial CAD-likelihood estimates and impressions of probable cause for the patient's symptoms, which were based on history only, the participants in all three groups were given the same laboratory data and a second CAD-likelihood estimate was made. Finally, recommendations for further workup were elicited. RESULTS: Initial diagnostic impressions differed dramatically: a cardiac cause was suspected by 50% of physicians viewing the businesslike portrayal but by only 13% of those viewing the histrionic portrayal. Likewise, those viewing the histrionic and businesslike videos provided different CAD-likelihood estimates initially (10% vs 20%). However, after the patient's laboratory data were revealed, the difference in CAD-likelihood estimates was no longer significant. Despite their making a similar risk appraisal after receiving all of the data, internists viewing the histrionic portrayal were far less likely to pursue a cardiac workup (53% vs 93%). CONCLUSIONS: Although physicians may evaluate patients who have the same history word for word and the same laboratory data and whom they regard as having nearly identical likelihoods of CAD, the physician's ultimate diagnostic approach can be profoundly affected by the patient's presentation style.

Psychiatric disorders and functional impairment in patients with persistent dizziness.

OBJECTIVE: To determine the prevalence and predictors of psychiatric dizziness and to measure functional impairment associated with dizziness. DESIGN: Consecutive outpatients with a chief complaint of dizziness. SETTING: Four outpatient clinics at a military teaching hospital. PATIENTS: 100 dizzy patients and 25 control patients. MEASUREMENTS AND MAIN RESULTS: Structured psychiatric interviews were conducted using the Diagnostic Interview Schedule, and functional status was assessed with the Sickness Impact Profile and the 20-item MOS (Medical Outcomes Study) Short-Form. Psychiatric disorders were a primary or contributory cause of dizziness for 40% of the dizzy patients. Compared with the control patients, the dizzy patients had a higher lifetime (46% vs 32%) as well as recent (37% vs 20%) prevalence of axis I disorders. The greatest differences were in disorders of depression and somatization. The dizzy patients had a higher lifetime prevalence (23% vs 8%) as well as recent history (11% vs 0%) of major depression or dysthymia. Also, somatization disorders were strikingly more common among the dizzy patients than among the control patients (37% vs 8%, p = 0.005), with the dizzy patients reporting more than three times as many psychiatric or unexplained physical symptoms (5.2 vs 1.5). Age < 40 years, related complaints of weakness or headaches, and dizziness provoked by hyperventilation or standing were independent predictors of psychiatric dizziness. The dizzy patients reported moderate functional impairment, which was most severe among those with psychiatric disorders. CONCLUSIONS: Persistent dizziness is associated with increased functional impairment and psychiatric comorbidity, particularly depression and somatization. Moreover, psychiatric disorders aggravate the impairment that occurs with dizziness alone.
