Survey on centres and procedures for the diagnosis and treatment of adult ADHD in public services in Italy.

Attention deficit/hyperactivity disorder (ADHD) often persists into adulthood. Although its persistence and relative high prevalence, ADHD in adults is often underdiagnosed and undertreated in Italy, leading to poor clinical and functional outcomes, and higher costs of illness. The aims of the study were to identify the Italian mental health services for ADHD in adults, describe the diagnostic and treatment procedures they follow, and compare this offer with the recommendations of the German and English guidelines. The centres, that adopt a clinical and assessment protocol for adult ADHD diagnosis (carried out by specifically trained personnel) and prescribe pharmacological treatment for adult ADHD, were selected from the list of accredited services provided by the Appendix B.2 of the ISTISAN 16/37 Reports of the ISS. An ad-hoc survey including open-ended and close-ended questions was sent to each selected centre in February 2020. The overall picture resulting from the data analysis was compared with the recommendations of the German and English guidelines. The present survey shows that only a few centres are specialised in the diagnosis and treatment of ADHD in adults in Italy. Furthermore, there are no national guidelines for adult ADHD in Italy. The collected data also suggest that there is no a unified practice shared by the Centres both for the patient's transition from child and adolescent to adult mental health services and for the diagnostic-therapeutic process. It is therefore crucial to create specific protocols and develop national guidelines to better identify and diagnose ADHD in adults and provide targeted and more efficient multimodal treatments.

Sleep quality among adults with attention deficit hyperactivity disorder or autism spectrum disorder: which is the role of gender and chronotype?

Both Attention Deficit Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD) present increased prevalence rates of sleep difficulties, which persist into adulthood. However, it is still unclear whether in adults these disorders show specific sleep patterns and which role is played by comorbidities, circadian preferences and gender. This study aimed to describe and compare subjective measures of sleep in adults with ADHD and high-functioning ASD, in relation to the levels of anxiety and depression, chronotype and gender. In a sample of 136 adults (43 ADHD, 43 high-functioning ASD, 50 controls) subjective sleep quality was measured with the Pittsburgh Sleep Quality Index (PSQI), and clinical scales were used to assess chronotype and the levels of anxiety and depression. The three groups showed a significant difference in the distribution of chronotypes, with greater prevalence of an Evening chronotype among ASD compared to controls. The MANCOVA using PSQI subscale scores as dependent variables and MEQ-SA score and depression range as covariates showed that the three groups significantly differ in quality, latency, efficiency, and dysfunction scores with a significant differences between ASD and ADHD in efficiency and dysfunction. Compared to men, women showed higher scores on PSQI total and quality subscale across the three groups and higher duration scores only within ASD group. Our results indicate that both ADHD and ASD adults show unique sleep disturbances and suggest that ASD patients, especially women, may display more pronounced disordered sleep.

ADHD in adults: clinical subtypes and associated characteristics.

INTRODUCTION: Attention Deficit Hyperactivity Disorder (ADHD) is an early onset clinical condition characterized by attention difficulties, hyperactivity and impulsivity which can persist across the lifespan, significantly influencing the evolutionary course and facilitating the rise of psychiatric comorbidities. The presence of different ADHD subtypes in adults is a heterogeneity factor to be recognized in order to orient prognosis and treatment, as indicated by studies that described differences in the characterization of different subtypes in relation to both severity and comorbidities. MATERIALS AND METHODS: In the present study we evaluated the socio-demographic and clinical characteristics of a sample of adults with ADHD and the characteristics associated with the different disorder subtypes. We described 60 patients aged between 18 and 65 years (mean age 34.1) with primary diagnosis of ADHD consecutively admitted to the Regional Centre for diagnosis and treatment of ADHD in adults in Milan. RESULTS: We observed high severity of symptoms and low quality of life, in particular in the "life outlook" dimension. The subtypes distribution was the following: 18.3% inattentive subtype, 8.3% hyperactive/impulsive subtype and 70% combined subtype. The hyperactive/impulsive subtype showed a significantly higher frequency in females, while the inattentive subtype was more frequent in males. Patients with the hyperactive/impulsive subtype showed worse quality of life and more frequent anxiety disorders. CONCLUSIONS: Considering the different clinical profiles among various subtypes, these data add relevance to subtypes classification of adult ADHD.
