Influence of Moyamoya disease on psychopathological abnormality in young males in Korea: analysis of multiphasic personal inventory test

Psychiatric manifestations in moyamoya disease: more than a puff of smoke? a systematic review and a case-reports meta-analysis

Introduction

Moyamoya disease (MMD) is a life-threatening condition characterized by stenosis of intracranial arteries. Despite the frequency and the impact of psychiatric symptoms on the long-term prognosis and quality of life of MMD patients, no systematic review on this topic exists.

Methods

This systematic review and meta-analysis included 41 studies (29 being case reports), from PubMed, Scopus, Embase until 27/3/2023, on MMD patients exhibiting psychiatric symptoms.

Results

Despite a fair average quality of the articles, quantitative synthesis through logistic regression was possible only for case reports, due to heterogeneity between the other studies. Psychosis, the most frequent psychiatric symptom reported in case reports, was more frequent in MMD patients with left hemisphere involvement. Neurological symptoms occurrence increased the odds of MMD diagnosis preceding psychiatric symptoms. Psychiatric symptoms are highly prevalent in MMD patients and are relatively often the only presenting symptoms.

Discussion

We discuss the diagnostic, therapeutic, and prognostic implications of recognizing and characterizing specific psychiatric symptoms in MMD, outlining preliminary guidelines for targeted pharmacological and psychotherapeutic interventions. Lastly, we outline future research and clinical perspectives, striving to enhance the oft-overlooked psychiatric care for MMD patients and to ameliorate their long-term outcome.

Impact of adolescent complex regional pain syndrome on the psychopathology of young men ahead of military service: a retrospective cohort analysis of Korean conscription data

BACKGROUND

The relationship between physical and psychopathological features in complex regional pain syndrome (CRPS) has been a subject of constant interest, but no data are available in adolescents. Therefore, we aimed to identify the factors associated with psychopathology in adolescents with CRPS ahead of military service.

METHODS

We retrospectively reviewed all conscription examinees who had completed a Military Personality Inventory (MPI) during a period between February 2013 and December 2016. A total of 63 persons with a history of CRPS (19-years of age for all) were enrolled. Basic demographic and pain-related data were analyzed to examine their association with MPI results. The mean FGR score as well as the 8 subdomain scores were compared between those with pain duration at < 15 months (n = 30) versus ≥15 months (n = 33). Binary MPI results (normal-abnormal) were also compared between the two groups.

RESULTS

In multivariate analysis, abnormal MPI was associated with pain duration, with an odds ratio (OR) at 1.05 for every 1-month increase (95% confidence interval (CI) 1.02-1.08; P = 0.002). Subjects with pain duration at ≥15 months have lower faking good response score (P < 0.001 vs. those with pain duration at < 15 months), and higher abnormal MPI result rate, faking bad response, inconsistency, anxiety, depression, somatization, paranoid, personality disorder cluster A, and personality disorder cluster B scores (P < 0.05). Pain duration was significantly associated with the MPI variables.

CONCLUSIONS

Pain duration is associated with psychopathology in adolescents with CRPS. Psychopathologic features increased as the disease duration increased. A comprehensive understanding of time-dependent psychopathological factors could support the planning of multimodal approaches for managing adolescent CRPS.

Increased Risk of Psychopathological Abnormalities in Subjects With Unilateral Hearing Loss: A Cross-Sectional Study

Objectives

Although unilateral hearing loss (UHL) has been proven to be associated with educational and behavioral problems, few studies have investigated psychopathological abnormalities in this population. The aim of this study was to evaluate the psychopathological influence of UHL among Korean 19-year-old males.

Methods

The authors retrospectively compared the objective personality test profiles of 602 subjects with UHL with those of 23,790 peers with normal hearing. All participants in the current study were 19-year-old males who underwent a physical examination and completed the Korean Military Multiphasic Personality Inventory for conscription at the Military Manpower Administration from February 2015 to December 2016.

Results

Significantly higher scores were found on neurosis scales in the UHL group than in the normal-hearing group (50.9± 10.8 vs. 44.9±6.0 for anxiety; 51.0±10.5 vs. 44.9±5.2 for depression; 51.1±10.4 vs. 45.1±6.81 for somatization, all P<0.001). The psychopathy scales were also significantly higher in the UHL group than in the normal-hearing group (49.3±9.4 vs. 46.3±5.7 for schizophrenia; 51.1±11.2 vs. 44.3±5.8 for personality disorders; 51.1±10.5 vs. 45.7±3.7 for paranoia, all P<0.001).

Conclusion

Nineteen-year-old males with UHL tended to have more abnormal results on personality tests than controls with normal hearing, suggesting that UHL may be related with a higher risk of psychopathology.

Psychopathological Influence of Middle Fossa Arachnoid Cysts in Young Men: Analysis of Korean Conscription Data

BACKGROUND

A few reported studies have documented psychotic syndromes secondary to a middle fossa arachnoid cyst (AC). However, the association between middle fossa ACs and psychopathological symptoms remains to be determined. The present study investigated the psychopathological effects of middle fossa ACs in young men.

METHODS

We reviewed military personal inventory test profiles and baseline demographic data of 19-year-old conscription examinees from February 2013 to December 2016. In total, 132 examinees with middle fossa ACs and 350 examinees with normal findings were enrolled in the present study. Two separate comparisons were performed. First, we compared the middle fossa AC group with the control group. Second, the middle fossa AC group was divided into 2 groups according to cyst size and compared with the control group.

RESULTS

Faking bad response behavior, infrequency, inconsistency, depression, schizophrenia, paranoia, and personality disorder cluster A scales were significantly associated with the presence of a middle fossa AC. Abnormal responses to the military personal inventory were significantly and positively correlated with cyst size. The prediction rate to show abnormal psychological results with the presence of an AC was estimated to be 60.7%-68.8%.

CONCLUSIONS

The presence of ACs and cyst size were associated with psychopathology in this select group of young men. The size-dependent psychopathological effects of ACs appear to result from a local mass effect on the brain.
