Background: Transcranial photobiomodulation (tPBM) has recently emerged as a potential cognitive enhancement technique and clinical treatment for various neuropsychiatric and neurodegenerative disorders by delivering invisible near-infrared light to the scalp and increasing energy metabolism in the brain. Objective: We assessed whether transcranial photobiomodulation with near-infrared light modulates cerebral electrical activity through electroencephalogram (EEG) and cerebral blood flow (CBF). Methods: We conducted a single-blind, sham-controlled pilot study to test the effect of continuous (c-tPBM), pulse (p-tPBM), and sham (s-tPBM) transcranial photobiomodulation on EEG oscillations and CBF using diffuse correlation spectroscopy (DCS) in a sample of ten healthy subjects [6F/4 M; mean age 28.6±12.9 years]. c-tPBM near-infrared radiation (NIR) (830 nm; 54.8 mW/cm2; 65.8 J/cm2; 2.3 kJ) and p-tPBM (830 nm; 10 Hz; 54.8 mW/cm2; 33%; 21.7 J/cm2; 0.8 kJ) were delivered concurrently to the frontal areas by four LED clusters. EEG and DCS recordings were performed weekly before, during, and after each tPBM session. Results: c-tPBM significantly boosted gamma (t = 3.02, df = 7, p

Adults with attention deficit/hyperactivity disorder (ADHD) often present psychiatric comorbidities and, in particular, substance use disorder (SUD). ADHD-SUD comorbidity is characterized by greater severity of both disorders, earlier age of onset, higher likelihood of polydrug-abuse and suicidal behaviors, more hospitalizations, and lower treatment adherence. At the present stage, research focused on the pharmacological management of ADHD with comorbid SUD in both adolescents and adults is still lacking. Furthermore, while the short-term effects of stimulants are well studied, less is known about the chronic effects of these drugs on dopamine signaling. Current available evidence is consistent in reporting that high doses of stimulant medications in ADHD-SUD subjects have a mild to moderate efficacy on ADHD symptoms. Some data suggest that pharmacological treatment with stimulants may be beneficial for both ADHD symptoms and comorbid cocaine or amphetamine use. However, in the long run, stimulant medications may have a potential risk for misuse. For the absence of potential misuse, atomoxetine is often recommended for ADHD with comorbid cocaine or amphetamine use disorder. However, its efficacy in reducing addictive behavior is not demonstrated. In subjects with other subtypes of SUD, both atomoxetine and stimulant drugs seem to have scarce impact on addictive behavior, despite the improvement in ADHD symptomatology. In this population, ADHD treatment should be combined with SUD-specific strategies.

Substance Use Disorders (SUDs) are often associated with Attention-Deficit Hyperactivity Disorder (ADHD) in adult populations due to multiple neurobiological, genetic, and psychosocial risk factors. This chapter provides a picture of the clinical aspects of adults with both ADHD and SUDs at treatment entry into a Dual Disorder Unit introducing the concept of different types of craving that may lead to substance use and abuse. At treatment entry, the presence of different comorbid SUD clusters, characterized by either stimulants/alcohol or by the use of cannabinoids, has not been shown to influence ADHD-specific symptomatology or severity, despite being crucial for the identification of a specific type of craving. We identified four clinical presentations of adult ADHD: Emotional Dysregulation, Substance Use, Core-ADHD Symptoms, and Positive Emotionality variants, that offer a practical guide in diagnosing and managing adult ADHD patients. Although the evidence of an effective medical treatment for Cocaine Use Disorder is insufficient, in our experience, toxicomanic behavior during stimulant treatment is sharply reduced in ADHD patients with cocaine addiction. Moreover, caffeinated compounds in military soldiers with ADHD may help reduce ADHD symptoms, making caffeine a potential pharmacological tool worth further investigation. Finally, substance use comorbidity does not influence treatment retention rate.

Background and Objectives: Emotional dysregulation is central to the problem of the overlap between attention-deficit/hyperactivity disorder (ADHD) and cyclothymia. The aim of the study was to evaluate comorbidity rates between ADHD and cyclothymic disorder and to explore demographic and clinical differences among the groups, focusing on affective temperament and emotional dysregulation. Materials and Methods: One hundred sixty-five outpatients attending the Second Psychiatry Unit at the Santa Chiara University Hospital (Pisa) were consecutively recruited: 80 were diagnosed with ADHD, 60 with cyclothymic disorder, and 25 with both conditions. Temperament Evaluation of Memphis, Pisa, Paris, and San Diego (TEMPS-M) and the 40-item version of Reactivity, Intensity, Polarity, and Stability questionnaire (RI-PoSt-40) were administered. Results: Cyclothymic patients were more frequently female and older with respect to the ADHD groups. Both comorbid and non-comorbid ADHD patients showed significantly lower educational attainment and more frequently had substance use disorders. Panic disorder was common in non-comorbid cyclothymic patients, who showed significantly higher rates of familial panic disorder, major depressive disorder and suicide attempts in comparison with patients only diagnosed with ADHD. Cyclothymic patients without ADHD were also characterized by fewer hyperthymic temperamental traits, higher depressive and anxious dispositions, and a greater negative emotionality. No significant differences among groups were observed for cyclothymic temperament and overall negative emotional dysregulation, but comorbid patients with both conditions scored the highest in these subscales. This group also showed significantly higher affective instability with respect to ADHD patients without cyclothymia and was less frequently diagnosed with bipolar disorder type II than patients from both the other groups. Conclusions: ADHD and cyclothymia often co-occur and show similar levels of emotional dysregulation. However, cyclothymic patients may be more prone to negative emotionality in clinical settings. Subjects with “sunny” cyclothymic features might escape the attention of clinicians unless ADHD is present.

Differentiating bipolar disorder from unipolar depression is one of the most difficult clinical questions posed in pediatric psychiatric practices, as misdiagnosis can lead to severe repercussions for the affected child. This study aimed to examine the existing literature that investigates brain differences between bipolar and unipolar mood disorders in children directly, across all neuroimaging modalities. We performed a systematic literature search through PubMed, PsycINFO, Embase, and Medline databases with defined inclusion and exclusion criteria. Nine research studies were included in the systematic qualitative review, including three structural MRI studies, five functional MRI studies, and one MR spectroscopy study. Relevant variables were extracted and brain differences between bipolar and unipolar mood disorders in children as well as healthy controls were qualitatively analyzed. Across the nine studies, our review included 228 subjects diagnosed with bipolar disorder, 268 diagnosed with major depressive disorder, and 299 healthy controls. Six of the reviewed studies differentiated between bipolar and unipolar mood disorders. Differentiation was most commonly found in the anterior cingulate cortex (ACC), insula, and dorsal striatum (putamen and caudate) brain areas. Despite its importance, the current neuroimaging literature on this topic is scarce and presents minimal generalizability.

The main aim of this study was to examine the body of knowledge on the prevalence of Attention Deficit Hyperactivity Disorder (ADHD) in “high-risk” children whose parents are diagnosed with ADHD. This knowledge could aid early identification for children presenting with ADHD symptoms at a young age. We conducted a systematic search of the literature assessing high-risk children. Included were original articles published in English with the main aim to assess prevalence of ADHD in high risk children. In addition, a meta-analysis was conducted to examine this prevalence. Four articles met our inclusion and exclusion criteria all suggesting an increased prevalence of ADHD in children of parents with ADHD. The meta-analysis also confirmed the increased prevalence of ADHD in high-risk children. The literature indicates that children of ADHD parents have an increased risk of developing ADHD compared to control children.

The Mountain Activities Neuro-behavioural Research Programme is a research project born in the 2 nd Unit of Psychiatry, Department of Clinical and Experimental Medicine at the University of Pisa to investigate the effects of altitude on the mental and neuro-behavioural aspects of people performing activities in mountainous areas.In this study, after elaborating a standardised data collection form, based on traditional psychopathology notions, to classify the misperceptions reported by the athletes taking part, we investigated the various types of these misperceptions in 21 athletes (including only one female), with a mean age of 44.90 ± 8.51 (min 33 and max 58).The athletes reported different kinds of misperceptions. It was possible to highlight three different clusters of athletes, based on the similarities between the kinds of misperceptions reported in each cluster: (a) anomalies in the intrinsic characteristics of perceptions (i.e. depersonalisation and derealisation), (b) illusions and (c) hallucinations.This study supports the concept that anomalous perceptual experiences may occur independently of the context of psychiatric or neurological disorders. The chance of observing hallucinatory phenomena outside the context of psychiatric disorders and in extreme environmental conditions among ultra-trail runners may offer a unique opportunity to those intending to study psychopathological conditions in a 'para-physiological' context.

Background: While a large amount of medical literature has explored the association between Attention Deficit/Hyperactivity Disorder (ADHD) and Substance Use Disorders (SUDs), less attention has been dedicated to the typologies of SUD and their relationships with ADHD-specific symptomatology and general psychopathology in dual disorder patients. Methods: We selected 72 patients (aged 18&ndash, 65) with a concomitant SUD out of 120 adults with ADHD (A-ADHD). Assessment instruments included the Diagnostic Interview for ADHD in adults (DIVA 2.0), Conner&rsquo, s Adult ADHD Rating Scales&ndash, Observer (CAARS-O:S): Short Version, the Structured Clinical Interview for Axis I and II Disorders (SCID-I), the Barratt Impulsiveness Scale (BIS-11), the Brief Psychiatric rating scale (BPRS), the Reactivity Intensity Polarity Stability Questionnaire (RIPoSt-40), the World Health Organization Disability Assessment Schedule (WHODAS 2.0) and the Morningness-Eveningness Questionnaire (MEQ). A factorial analysis was performed to group our patients by clusters in different typologies of substance use and correlations between SUDs, as made evident by their typological and diagnostic features, in addition, specific ADHD symptoms, severity of general psychopathology and patients&rsquo, functionality were assessed. Results: Two patterns of substance use were identified: the first (type 1) characterized by stimulants/alcohol and the second (type 2) by the use of cannabinoids (THC). Type 1 users were significantly younger and had more legal problems. The two patterns were similar in terms of ADHD-specific symptomatology and its severity at treatment entry. No differences were found regarding the other scales assessed, except for lower scores at MEQ in type 1 users. Conclusions: At treatment entry, the presence of different comorbid SUD clusters do not affect ADHD-specific symptomatology or severity.

The purpose of the study was to assess the prevalence and clinical correlates of Delayed Sleep Phase Disorder (DSPD) in adults with Attention-Deficit/Hyperactivity Disorder. Participants were 102 adults (Female= 27), aged 18-65 (mean age= 28.2 years), with ADHD diagnosed in adulthood. ADHD and DSPD diagnosis were made according to DSM-5 criteria. Assessing instruments included the Morningness-Eveningness Questionnaire, the brief Temperament Evaluation of Memphis, Pisa, Paris and San Diego Questionnaire, the Barratt Impulsiveness Scale, the Reactivity Intensity Polarity Stability Questionnaire-40 and the World Health Organization Disability Assessment Schedule 2.0. Epidemiological and Clinical features were compared in patients with and without DSPD. 34 out of 102 patients were classified as having a Delayed Sleep Phase Disorder. As expected, DSPD patients reported a more frequent evening chronotype. In the multivariate logistic regression analysis, Delayed Sleep Phase Disorder was significantly associated with young age, cannabis use, cyclothymic temperamental traits and severe global impairment. An early diagnosis with a proper treatment targeted to both disorders may be fundamental in order to improve the overall functioning and the outcome of adult ADHD patients.

Photobiomodulation also called “low-level light therapy” or “low-level laser therapy” is a novel device-based treatment used in a variety of conditions including muscle pain, wounds, neuropathic pain, headache, periorbital wrinkles, and alopecia and is currently under investigation for different psychiatric conditions, including anxiety disorders.

ObjectiveOur objective was to assess whether transcranial photobiomodulation (tPBM) with near-infrared light (NIR) shows modulatory effects on cerebral electrical activity through electroencephalogram (EEG) and cerebral blood flow (CBF).BackgroundtPBM has emerged as a novel intervention for several neuropsychiatric conditions due to its neuroprotective and neuroenhancement effects.MethodsWe conducted a single-blind, sham-controlled pilot study to test the effect of continuous (c-tPBM), pulse (p-tPBM) and sham (s-tPBM) transcranial photobiomodulation on EEG oscillations and CBT using diffuse correlation spectroscopy (DCS) in a sample of ten healthy subjects [6 F/ 4 M; mean age 28.6 ± 12.9 (SD) years]. c-tPBM NIR (830 nm; 54.8 mW/cm²; 65.8 J/cm²; 2.3 kJ) and p-tPBM (830 nm; 10Hz; 54.8 mW/cm²; 33%; 21.7 J/cm²; 0.8 kJ) were delivered concurrently to the frontal areas (F4, Fp2, Fp1, F3 - total surface 35.8 cm²) by four LED clusters (TPBM-1000 Litecure). EEG and DCS recordings were performed weekly before, during, and after each tPBM session (in sequence: c-tPBM, s-tPBM and p-tPBM).ResultsOnly c-tPBM significantly boosted gamma (t = 3.02, df = 7, p < .02) and beta (t = 2.91, df = 7, p < .03) EEG spectral powers in eyes-open recordings and gamma power (t = 3.61, df = 6, p < .015) in eyes-closed recordings, with the largest effects in the posterior regions. There was no significant effect of NIR-tPBM on CBF compared to sham.ConclusionsOur data suggest a dose-dependent effect of tPBM with NIR (c-tPBM) on cerebral gamma and beta neuronal activity. Altogether, our findings support the neuromodulatory effect of transcranial NIR.

Objective: Our aim was to test the anxiolytic effect of transcranial photobiomodulation (t-PBM) with near-infrared light (NIR) in subjects suffering from generalized anxiety disorder (GAD). Background: t-PBM with NIR is an experimental, noninvasive treatment for mood and anxiety disorders. Preliminary evidence indicates a potential anxiolytic effect of transcranial NIR. Methods: Fifteen subjects suffering from GAD were recruited in an open-label 8-week study. Each participant self-administered t-PBM daily, for 20 min (continuous wave; 830 nm peak wavelength; average irradiance 30 mW/cm(2); average fluence 36 J/cm(2); total energy delivered per session 2.9 kJ: total output power 2.4 W) broadly on the forehead (total area 80 cm(2)) with an LED-cluster headband (Cerebral Sciences). Outcome measures were the reduction in total scores of the Hamilton Anxiety Scale (SIGH-A), the Clinical Global Impressions-Severity (CGI-S) subscale and the Pittsburgh Sleep Quality Index (PSQI) subscales from baseline to last observation carried forward. Results: Of the 15 recruited subjects (mean age 30 ± 14 years; 67% women), 12 (80%) completed the open trial. Results show a significant reduction in the total scores of SIGH-A (from 17.27 ± 4.89 to 8.47 ± 4.87; p

Background Traumatic fractures of the thoracolumbar spine are common injuries, accounting for approximately 90% of all spinal traumas. Optimal management of these fractures still gives rises to much debate in the literature. Currently, one of the treatment options in young patients with stable traumatic vertebral fractures is conservative treatment using braces. Kyphoplasty as a minimally invasive procedure has been shown to be effective in stabilizing vertebral body fractures, resulting in immediate pain relief and improved physical function with early return to work activity. The aim of the study is to report VAS, ODI scores, and kyphosis correction following treatment. Methods This is a retrospective study to investigate the clinical and radiological results 10 years after percutaneous balloon kyphoplasty followed by cement augmentation with polymethylmethacrylate (PMMA) or calcium phosphate cements (CPC), according to age, in 85 consecutive patients affected by 91 AOSpine type A traumatic fractures of the thoracolumbar spine (A1, A2, and A3). Clinical follow-up was performed with the Visual Analogic Scale (VAS) at the preoperative visit and in the postoperative follow-up after 1 week, 1, 6, 12 months, and each year up to 10 years. Additionally, the Oswestry Disability Index (ODI) improvement was calculated as the difference between the ODI scores at the preoperative visit and at final follow-up. Finally, the Cobb angle from this cohort was assessed before surgery, immediately postoperatively, and at the end of follow-up. Results Kyphoplasty markedly improved pain and resulted in statistically significant vertebral height restoration and normalization of morphologic shape indexes that remained stable for at least 10 years following treatment. Conclusions The present study showed that kyphoplasty and cement augmentation are an effective method of treatment for selected type A fractures.

Background Over-standard methadone doses are generally needed in the treatment of heroin use disorder (HUD) patients that display concomitant high-severity psychopathological symptomatology. A flexible dosing regimen may lead to higher retention rates in dual disorder (DD), as we demonstrated in bipolar 1 HUD patients, leading to outcomes that are as satisfactory as those of HUD patients without high-severity psychopathological symptomatology. Objective This study aimed to compare the long-term outcomes of treatment-resistant chronic psychosis HUD patients (PSY-HUD) with those of peers without dual disorder (HUD). Methods 85 HUD patients who also met the criteria for treatment resistance—25 of them affected by chronic psychosis and 60 without DD—were monitored prospectively for up to 8 years while continuing to receive enhanced methadone maintenance treatment. Results The rates of endurance in the treatment of PSY-HUD patients were 36%, compared with 34% for HUD patients (p = 0.872). After 3 years of treatment, these rates tended to become progressively more stable. PSY-HUD patients showed better outcome results than HUD patients regarding CGI severity (p

Introduction: The severity of emotional responses to life events (PTSD spectrum) as part of Post Traumatic Stress Disorder (PTSD) in Substance Use Disorder (SUD) patients has often been considered from a unitary perspective. Light has also been shed on the possible definition of a specific psychopathology of SUD patients. This psychopathology has been proved to be independent of treatment choice, of being active in using substances, of lifetime psychiatric comorbidity and primary substance of abuse (heroin, alcohol, cocaine). Methods: To further support this unitary perspective, in this study we have compared the severity and typology of the five psychopathological dimensions found in SUD patients, by dividing 93 HUD patients (77.4% males and 22.6% females), characterized by the lifetime absence of exposure to actual or threatened death, serious injury, or sexual violence, on the basis of the severity of their PTSD spectrum. We used the cut-off that differentiated people developing (High PTSD spectrum; H-PTSD/S) or not developing (Low PTSD spectrum; L-PTSD/S) a PTSD after the earthquake that hit L'Aquila, Italy, in April 2009. Results: Using a canonical correlation analysis, the significant (p

The present paper reconstructs the main stages of development of a new form of cooperative society that has become established in Italy over the last 20 years. A general view of the evolution of this phenomenon, which has spread over the whole country in a relatively short time, is followed by an analysis of some key issues: the content of the regulation that recognised its existence, its relationship with the conventional cooperative movement and the non-profit sector organizations, forms of representation and communication, and the competitive edge elements that characterise social cooperative societies.

The authors describe the case of a 47-year-old woman with a wide (14 × 12–cm) ulcerated lumbosacral myelomeningocele. The patient had sought medical attention for a sudden copious CSF leak from the lumbosacral sac followed by clinical signs of CSF leakage. After admission, neuroradiological assessment (spinal MR and 3D CT imaging) revealed the uncommon finding of a complex malformation characterized by a complete spine duplication originating at the L2–3 level, both hemicords having a separate dural sac. The myelomeningocele sac originated medially at the L-2 level. Surgical repair of the lumbosacral myelomeningocele was performed. The placement of a ventriculoperitoneal shunt became necessary to treat secondary hydrocephalus. After reviewing accredited classifications on spinal cord malformations, the authors believe that, to date, complete duplication and separation of the spine and dural sac seems exceptional, and its report in adulthood appears exceedingly rare.
