Psychiatric disorders, personality and neuropsychological alterations in Erdheim-Chester disease

[摘要] Although neurological manifestations and changes in brain volumes have been described in Erdheim-Chester disease (ECD), it remains unknown whether ECD may be associated with psychiatric symptoms and cognitive dysfunctions. We assessed the presence of psychiatric disorders, changes in temperaments and characters, and neuropsychological performances in 32 ECD patients (mean age = 59) younger than 70, not treated with interferon alpha during the last 6 months, and without other serious illnesses. ECD patients exhibited high level of past depressive disorder (80%) and anxiety disorder, especially agoraphobia (29%). They revealed personality changes, especially with high agreeableness (t = 3.18, p < 0.005) and high conscientiousness (t = 3.81, p < 0.001). Neuropsychological assessments showed impairments in attention (GZ: t = 16.12, p < 0.0001, KL: t = 37.01, p < 0.0001) and episodic memory performances (STIR: t = − 3.01, p = 0.006, LTFR: t = − 2.87, p = 0.008, LTIR: t = − 3.63, p = 0.001). Executive functions, such as flexibility, inhibitory control, were unimpaired. Although it remains to be clarified whether these psychiatric symptoms and cognitive impairments may impact the daily functioning and the quality of life, the present study highlights the need to consider cognitive and emotional states in ECD management.
