Involvement of mental health professionals in the treatment of tuberous sclerosis complex–associated neuropsychiatric disorders (TAND): results of a multinational European electronic survey

BACKGROUND: Tuberous sclerosis complex (TSC) is a rare, genetic, multisystem disorder characterized by the growth of hamartomas in several organs, including the brain, kidneys, heart, eyes, and lungs. Even though over 90% of patients will have some form of TSC-associated neuropsychiatric disorder (TAND), there is an apparent lack of involvement of mental health professionals (MHPs) in the care of patients with TSC. The aim of this study was to determine the current level of TAND awareness in the TSC community and to identify possible barriers to effective multidisciplinary collaboration between MHPs and other healthcare providers (HCPs) in TAND management. METHODS: An electronic survey on current TSC and TAND management was conducted, targeting TSC caregivers/families, psychiatrists, neurologists, TSC specialists, and primary care physicians. RESULTS: The invitation to participate in the survey was emailed to 659 HCPs and was disseminated through social media channels of patient advocacy groups. The survey was open for 4 months, with 359 responses collected. The majority of participants were TSC caregivers/families (73.3% of all responses). Of the 96 HCPs who participated, most were neurologists (61.5%) or TSC specialists (28.1%). Only 6 psychiatrists and 4 primary care physicians participated. Approximately half of patients have never had a neuropsychiatric assessment, and it was their caregivers/families who initiated the discussion of TAND with their providers. Almost 70% of TSC caregivers/families believed that psychiatric treatment could improve their quality of life. However, 54% of patients had difficulty obtaining psychiatric assessment. In turn, only 21% of HCPs believed that psychiatric therapy would help and 74% were concerned that their patients would be stigmatized by psychiatric referral. CONCLUSIONS: This study focused on European healthcare systems suggests that current care for mental health issues in patients with TSC is inadequate, despite guideline recommendations for regular neuropsychiatric assessments. This appears to be due to a combination of gaps in diagnosis and surveillance, low frequency of psychiatric referrals, insufficient resources, and stigmatization of mental healthcare. There is a pressing need for further initiatives to study and address the mechanisms underlying the mental health treatment gap. The importance of MHP support must be recognized to optimize TSC management. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1186/s13023-021-01800-w.
