Filter by:The investigators therefore propose a pilot study to establish the effectiveness of NIRS Neurofeedback training in reducing the intensity of ADHD symptom expression on children, improvement of the cognitive and global functions associated with ADHD, effects on cerebral blood perfusion in the cortex and safety plus possible unknown side-effects.
ADHD children have executive function (EF) impairments,so we randomize the children to the training or a waitlist to improve EF ,adding contingent reinforcement to ascertain whether EF deficits are amenable to the training in children with ADHD.
Background Attention Deficit Hyperactivity Disorder (ADHD) is one of the most frequently diagnosed behavioural disorders in childhood that requires treatment(3-5% of children). It is an important health problem because it impairs social, educational and occupational performance, and increases the risk of other psychiatric disorders including anxiety, depression and substance misuse. There is no cure for ADHD and standard stimulant medication treatment is at best symptomatic. Moreover, stimulants have side effects and parents are often concerned over the long-term effects. A number of non-drug treatments have been developed but these do not target the brain directly. Neurofeedback Training (NTx) is a new, non-drug treatment that targets the brain directly and that can potentially enhance the control of attention in ADHD. NTx could be a valuable alternative and/or adjunct to standard care. Aims Although NTx has gained popularity in Europe and the US, more rigorous studies are required to support its implementation in the NHS. We therefore propose a pilot study to establish tolerabilty and safety, and to develop treatment protocols and collect data to design a follow-on controlled NTx trial in ADHD. Methods We plan an open label, single arm, treatment trial of near infrared spectroscopy neurofeedback training of frontal lobe activation in school-aged children with ADHD. 48 participants will be recruited over 1 year and will be offered 20 NTx sessions over 10 weeks. Participants will be recruited from Mental Health Services. Primary outcomes will be safety and tolerability and secondary outcomes will include standard clinical behavioural rating scales and the Test Of the Variables of Attention.
Attention deficit hyperactivity disorder (ADHD), characterized by inattention, hyperactivity and impulsivity, is an early onset, highly heritable, clinically heterogeneous, long-term impairing disorder with tremendous impact on individuals, families, and societies. It affects 5-10% of school-aged children worldwide (7.5% in Taiwan) and 2-4% of adults. Although the efficacy of medications for ADHD is well demonstrated in clinical trials, substantial numbers of patients fail to remain on therapy, and there is tremendous variability in tolerability and treatment acceptance. It is of great interest to identify biomarkers relating to medication response in ADHD. However, the procedure for obtaining central markers such as PET scan is invasive and expensive. Previous studies have found that mRNA expression of neurochemical markers in circulating blood can reflect the neurochemical levels in the brain. Further studies to identify peripheral biomarkers related to medication response in ADHD are warranted.
This study looks to examine whether or not INTUNIV extended release can help children aged 6-12 years diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD) in improving Executive Function when added to their usual care stimulant therapy. Executive functions are a set of mental processes that include emotional control, planning, organization, working memory, inhibition of behaviors, and managing time and space. As children with ADHD usually have difficulties with Executive Function, and Executive function difficulties lead to more difficulties in school and behaviour, it is anticipated that adding INTUNIV extended release to usual stimulant therapy will improve Executive Function scores as rated by parents and teachers. Improvements in quality of life will also be measured.
Background: TEAMS (Training Executive Attention and Motor Skills) is a non-pharmacological, neurocognitive intervention program targeted preschool children with ADHD developed by Professor Jeffrey Halperin, and his team from New York University. The uniqueness of this program lies in the concept, based on stimulating neurocognitive growth through focused physical activity and play (Halperin et al.; 2011, 2012, in press). Teams hypotheses: TEAMS is based on the notions that: 1. The behavioural manifestations of ADHD are the result of deficient neural networks that affect a wide array of neurocognitive and behavioural processes which are not necessarily identical in all children with the disorder. 2. Neurodevelopment is sensitive to and can be positively affected by appropriate environmental influences. 3. Effective environmental stimulation will be best achieved within a social context. 4. The engagement of the child in the core activities of the treatment must be intrinsically rewarding (i.e., fun) in order to facilitate compliance of the intervention. The initial research by Halperin et al. (2012)indicated significant improvement in ADHD severity from pre- to post-treatment, which also persisted 3 months later. Objective: The aim of this study is, through a randomized controlled trial (RCT), to validate the TEAMS treatment program in a clinical setting in Denmark. Method: Pre-school children age 3-6, from Region Zealand in Denmark, diagnosed with ADHD as primary diagnosis are offered participation in the RCT study of the TEAMS program. The control groups receive the standard treatment program, outlined by the clinical guidelines of Region Zealand. The intervention groups participate in eight weekly group sessions consisting of separate parent- and children's groups. In the child group the children are introduced to games that are designed to enhance inhibitory control, working memory, attention, visuospatial abilities, planning, and motor skills. The parent group consists of psychoeducation and instructions in how to encourage playing these games with their children and how to support the child's development.
The purpose of the study is to explore the effect of methylphenidate on state anxiety in children with attention deficit hyperactivity disorder. Patient population: 30 children diagnosed with attention deficit hyperactivity disorder. The subjects will be of all racial, ethnical and gender categories, ranging from 8 to 18 years of age. Structure: the study is a randomized double blind crossover study. The subjects will complete a continuous performance test, the cambridge neuropsychological test automated Battery, before and after given methylphenidate or placebo on the first day of the study. On the second day of the study, the subjects will receive either methylphenidate or placebo based on what was given on the first day of the study and they will complete the same task.
Brief summary The aim of the study is to provide preliminary data on the relationship of Essential Fatty Acids (EFAs) to cognitive and electrophysiological measures of brain and behavioural functions in adults with attention deficit hyperactivity disorder (ADHD) and controls. This main aim will be achieved in two ways. First the investigators will measure the relationship of the various measures to blood levels of EFAs in ADHD cases and controls. Secondly, the potential effects of dietary supplementation with EFAs on cognitive-electrophysiological and behavioural measures in ADHD cases will be investigated. We will evaluate the extent to which changes in neuronal activity and cognitive performance are related to behavioural and functional measures over time. This is to be carried out by conducting a randomised controlled trial of fish oil supplementation in adults with ADHD (The OCEAN study: Oils and Cognitive Effects in Adult Neurodevelopment). The study design will be a 6-month double blind placebo control study with a group of 80 adults with a diagnosis of ADHD. The group will be divided into 40 participants who receive EFA dietary supplements and 40 who receive placebo, over a 6-month period. Allocation to EFA dietary supplementation and placebo groups will be randomly allocated and blind to both the investigator and participants. In addition a sample of 30 controls will take part in baseline levels of assessment and be used for case-control comparisons to investigate the links between EFA blood levels and cognitive-electrophysiological function at one time point. The study design will enable preliminary data to address the following hypotheses: 1. Changes in cognitive and electrophysiological function (neuronal activity) will be found following supplementation with dietary EFAs. 2. Changes in cognition and/or brain activity will be related to blood levels of EFAs. 3. Changes in cognitive performance and electrophysiological parameters will correlate with behavioural function, affective regulation or functional impairments. 4. At baseline, case-control differences in EFA blood-levels will be found which will be linked to cognitive and electrophysiological function.
The overall objective of the current study is to determine whether computerized Working Memory (WM) training will enhance WM capacity in college students with Attention Deficit Hyperactivity Disorder (ADHD). There are also four additional objectives. The first is to investigate whether the program's efficacy is impacted by the duration of the daily training sessions. The second is to determine whether improvements in WM will generalize to secondary outcome tasks, such as inhibitory control and planning. The third objective is to examine whether WM training will also ameliorate ADHD symptoms of inattention and hyperactivity. The last objective is to investigate whether improvements will be maintained at a two month follow-up period. The investigators will also be assessing healthy control participants,who will not be receiving treatment, but will be used as a basis of comparison with the ADHD participants, It is expected that the computerized WM training program will enhance WM capacity in college students with ADHD. In addition, it is believed that these increases in WM capacity will also lead to improvements in other executive functions. It is also hypothesized that WM training will lead to a reduction in ADHD symptomology. Lastly, these improvements should be maintained at three month follow-up.
Even in the absence of a preliminary diagnosis of Attention Deficit Hyperactivity Disorder, symptoms of attention deficit, hyperactivity and cognitive impairment are common in cocaine addicts. Several factors indicate that repetitive transcranial magnetic stimulation might be a strategy to aid in the treatment of symptoms of attention deficit hyperactivity disorder and cognitive function in cocaine addicts. However, up to current days there have been no studies evaluating the effects of Repetitive Transcranial Magnetic Stimulation (rTMS) on neurocognitive performance of individuals suffering from the ADHD.
