Background: Obsessive Compulsive Tic Disorder (OCTD) has been described recently as an early onset and highly disabling endophenotype of Tic Disorder and Obsessive Compulsive Disorder. OCTD has a relevant but largely unknown clinical, social and economic burden for patients and their families. Our paper aimed to explore relevant aspects of the burden of OCTD, such as the etiological, clinical and epidemiological aspects of the condition, and implication of diagnosis and treatment on patients’ health and socio-economic impact. Methods: We conducted a literature review and a pilot study using retrospective demographic, clinical and economic data of patients with OCTD accessing the Galeazzi Hospital in Milan Result: The literature review shows the absence of information on OCTD. From the pilot study we analysed data of 30 patients (80.0% male, 36.7% aged from 7 to 13 years, 63.3% aged from 15 to 48 years), 83.0% declared that obsessions and/or compulsions were the most important factors determining their social impairment. Adult patients refractory to drug treatment underwent Deep Brain Stimulation plus drugs. The mean clinical scores at the time of diagnosis indicated a severe condition for both tics and obsessive compulsive components. The mean time elapsed from symptoms onset to diagnosis of OCTD was 5.6 years, reaching up to 11 years in one case. Before reaching the correct diagnosis, different specialists visited the patients several times, 93.3% underwent diagnostic examinations and 86.7% took 2 or 3 different drugs. Ten patients were hospitalised and 8 had received psychotherapy. Discussion: Albeit preliminary, these results show that attention is mandatory for establishing correct diagnosis and treatment guidelines to improve health and rationally spend resources for OCTD.

Once full blown, neuropsychiatric disorders are prevalent conditions that patients live with a great burden of disability. Indeed, the determinants that increase the affliction of neuropsychiatric disorders are various, with unhealthy lifestyles providing a significant contribution in the interplay between genetic, epigenetic, and environmental factors that ultimately represent the pathophysiological basis of these impairing conditions. On one hand, the adoption of Healthy Eating education, Physical Activity programs, and Sleep hygiene promotion (HEPAS) has the potential to become one of the most suitable interventions to reduce the risk to develop neuropsychiatric disorders, while, on the other hand, its integration with pharmacological and psychological therapies seems to be essential in the overall management of neuropsychiatric disorders in order to reduce the disability and improve the quality of life of affected patients. We present an overview of the current evidence in relation to HEPAS components in the prevention and management of neuropsychiatric disorders and provide suggestions for clinical practice.Keywords: neuropsychiatry, diet, motor activity, sleep, quality of health care

Gilles de la Tourette syndrome (GTS) is a neurodevelopmental disorder defined by multiple motor tics and at least one sound tic. Various behavioural symptoms are associated with GTS, especially obsession and compulsion behaviours (OCBs), attention-deficit/hyperactivity disorder (ADHD) and poor impulse control. These comorbid conditions have a high impact on patients quality of life, including eating attitudes and body image perception. Nutritional implications, together with sleepiness and sexual asthenia, are the principal side effects of the pharmacological therapy. Actually, drugs may compromise the nutritional status of patients producing appetite increase, dry mouth, constipation, glucose and lipid metabolism abnormalities, metabolic syndrome, mild transient dysphagia and nausea. About 40% of GTS patients experience hyperphagia because of drug side effects, OCBs, ADHD, or poor impulse control. Consequently, in these cases an overweight status can occur, complicating the management of the symptoms. Therefore, an increase body weight should be considered one of the most relevant factors increasing GTS drug-related bad compliance, which may consequently cause in some patients the discontinuation/interruption of the pharmacological therapy.

Preclinical and clinical studies suggest that many food molecules could interact with drug transporters and metabolizing enzymes through different mechanisms, which are predictive of what would be observed clinically. Given the recent incorporation of dietary modifications or supplements in traditional medicine, an increase in potential food-drug interactions has also appeared. The objective of this article is to review data regarding the influence of food on drug efficacy. Data from Google Scholar, PubMed, and Scopus databases was reviewed for publications on pharmaceutical, pharmacokinetic, and pharmacodynamic mechanisms. The following online resources were used to integrate functional and bioinformatic results: FooDB, Phenol-Explorer, Dr. Duke's Phytochemical and Ethnobotanical Databases, DrugBank, UniProt, and IUPHAR/BPS Guide to Pharmacology. A wide range of food compounds were shown to interact with proteins involved in drug pharmacokinetic/pharmacodynamic profiles, starting from drug oral bioavailability to enteric/hepatic transport and metabolism, blood transport, and systemic transport/metabolism. Knowledge of any food components that may interfere with drug efficacy is essential, and would provide a link for obtaining a holistic view for cancer, cardiovascular, musculoskeletal, or neurological therapies. However, preclinical interaction may be irrelevant to clinical interaction, and health professionals should be aware of the limitations if they intend to optimize the therapeutic effects of drugs.

Foods are natural sources of substances that may exert crucial effects on the nervous system in humans. Some of these substances are the neurotransmitters (NTs) acetylcholine (ACh), the modified amino acids glutamate and γ-aminobutyric acid (GABA), and the biogenic amines dopamine, serotonin (5-HT), and histamine. In neuropsychiatry, progressive integration of dietary approaches in clinical routine made it necessary to discern the more about some of these dietary NTs. Relevant books and literature from PubMed and Scopus databases were searched for data on food sources of Ach, glutamate, GABA, dopamine, 5-HT, and histamine. Different animal foods, fruits, edible plants, roots, and botanicals were reported to contain NTs. These substances can either be naturally present, as part of essential metabolic processes and ecological interactions, or derive from controlled/uncontrolled food technology processes. Ripening time, methods of preservation and cooking, and microbial activity further contributes to NTs. Moreover, gut microbiota are considerable sources of NTs. However, the significance of dietary NTs intake needs to be further investigated as there are no significant data on their bioavailability, neuronal/non neuronal effects, or clinical implications. Evidence-based interventions studies should be encouraged.

Tourette's syndrome (TS) is a developmental neurobehavioral disorder with childhood onset and relevant burden in terms of disability and reduced quality of life. In Italy the biological basis of this syndrome is still frequently ignored and TS is often recognised as a psychiatric manifestation, or even it is not recognised as pathology, which may result in inadequate treatment, social isolation and improper hospitalization. Indeed, the organic medical nature of TS needs to be taken into great consideration in evaluating causality of committing crimes in affected patients. In addition, delaying the diagnosis and consequently proper treatment has a devastating impact on social as well as legal aspects in patients with TS. The present report is aimed to present an Italian case series of 4 TS patients who faced legal problems related to their mental condition, in the intent to add further evidence, raise the level of awareness and encourage further investigation in the field, as in most of the cases, patients' illness was not taken into adequate account by the Justice. The relevant law is discussed in detail.

(1) Background: Literature suggests that high levels of dopamine are associated with creative thoughts. Tourette Syndrome (TS) patients have high dopamine levels, while Parkinson’s Disease (PD) subjects have low dopamine levels. Consequently, TS individuals are supposed to have a major and PD patients less creative output. Moreover, dopamine medications may alter the level of creativity, and therefore Quality of Life, in both pathologies. (2) Methods: The aim of the study was to verify the hypothesis of TS patients having higher creative scores than PD patients. The assessment consisted of the administration of the Creative Thinking ASK Test. There were 54 participants—36 males and 18 females—i.e., 27 TS patients and 27 PD subjects. Age of the sample was 35 to 57 years old, high school certificate was required. (3) Results: TS sample (103.11 ASK average score) was more creative than PD sample (94.11 ASK average score). (4) Conclusions: The results supported the aforementioned hypothesis: TS sample resulted in having higher creative scores than PD sample. Dopamine and other neurotransmitters of TS and PS appear to affect subject’s creativity. Further studies with creative assessments in TS and PD patients are needed to support the preliminary results of our study.

Tourette’s syndrome (TS) is a neurodevelopmental disorder typically defined by multiple motor tics and at least one sound tic (1), beginning in childhood or in adolescence. More recently, Tourette’s syndrome has been acknowledged as a broad spectrum syndrome (2), including different comorbidities and coexisting symptoms. When beginning in early childhood TS mainly presents with attention deficit and hyperactivity disorder (ADHD) and tics, when beginning in adolescence instead tics and obsessive-compulsive behavior or disorder (OCB/OCD) are predominant. OCB/OCD trait is present in 60-80% of patients (3), and they are considered as thought tics (4). In many cases motor and sound tics resolve spontaneously in adulthood, though OCB/OCD generally remain. Tics often interfere with subject’s daily activities (5) affecting Quality of Life and causing Social Impairment, particularly in schooling and working. Handwriting is one of the most impaired school activity for TS patients because of the tics presence that hamper learning processes. In our clinical experience handwriting tics (HT) could severely affect and condition TS subjects, but they are not often pointed out in the Literature. For this reason there are not precise data regarding the incidence of HT neither in Tourette’s syndrome patients nor in healthy population.

The aim of this paper was to perform a critical and systematic review of the published papers on deep brain stimulation (DBS) for Tourette's Syndrome (TS).A PubMed search on DBS in TS was conducted selecting papers that reported on the clinical outcome of DBS.The majority of papers were case reports or small series. The thalamus and the globus pallidus internus appear to be the most promising targets. However, in light of the great methodological diversity a balanced comparison of clinical outcome and understanding of the role of DBS in TS remains difficult.Despite 16 years of experience with DBS in TS a consensus on many issues, foremost on target selection and the age of inclusion continue to be missing. Class I evidence and international collaborations, to increase the number of included patients, are urgently needed, in order to evaluate further the role of DBS in TS.
