Psychiatric disorders, impulsivity and borderline personality in patients with polycystic ovary syndrome

Polycystic ovarian syndrome (PCOS) is a common endocrine condition in women. Studies have shown that PCOS is associated with poor quality of life, anxiety, sadness, dissatisfaction with one's appearance, and sexual dysfunction.

This study was conducted to determine whether a strong psycho-pathological personality is related to PCOS and whether this personality is related to the hyperandrogenic state.

Anthropometric, metabolic, hormonal, clinical, and psychological characteristics were examined in 90 Bahraini women with PCOS. After confirming the diagnosis of PCOS via Rotterdam criteria, including ovarian ultrasound, each patient was evaluated via the following questionnaires: 1) the GAD-7 (General Anxiety Disorder-7) to measure the severity of anxiety; 2) the Patient Health Questionnaire-9 (PHQ-9) to confirm and measure the severity of depression; 3) the Barratt Impulsiveness Scale (BIS-11) to measure aggression; and 4) the McLean Screening Instrument to identify borderline personality disorders (MSI-BPDs). The study was approved by the Institutional Review Board.

Compared to controls, PCOS patients exhibited significantly higher rates of severe depression (8% vs. 0%, p < 0.001), severe anxiety (7% vs. 0%, p < 0.001), impulsivity (BIS-11: 39.43 ± 9.69 vs. 26.64 ± 2.92, p < 0.001), and borderline personality traits (McLean: 2.41 ± 2.44 vs. 1.2 ± 0.94, p < 0.001). Metabolic comorbidities, including obesity (BMI 28.88 vs. 20.27, p < 0.001) and hypothyroidism (48% vs. 0%, p < 0.001), were prevalent in PCOS. Hyperandrogenism correlated weakly with psychiatric outcomes (all p > 0.05).

Women with PCOS demonstrate markedly elevated psychiatric and medical burdens compared to healthy controls. While hyperandrogenism showed limited direct associations, metabolic dysfunction (e.g., obesity) may mediate psychiatric risk. These findings underscore the need for multidisciplinary care integrating psychological and endocrine management, particularly in populations where cultural norms exacerbate PCOS-related distress.
