Abstract Although Attention Deficit Hyperactivity Disorder (ADHD) is a common childhood disease, objective diagnostic methods are insufficient still. Current diagnostic methods include the subjective influence of the evaluator. In this context, in our study, we aimed to minimize the subjective effect of the evaluator with the objective diagnosis support system for ADHD.In our study, a visual stimulus follow-up test developed by us was applied to the patient with ADHD and healthy individuals, and electrooculogram (EOG) signals were recorded simultaneously. With the features extracted from EOG signals, Artificial Neural Networks (ANN) were used for the classification study of patients and healthy individuals, and it was determined that the classification of ADHD and healthy group could be distinguished by 81.76% performance. Thus, the outcomes that will contribute to the objective diagnosis of ADHD have been presented. The results are remarkable and important findings have been obtained that will contribute to the literature.

AbstractBackgroundAttention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder which frequently persists into adulthood. The primary goal of the current study was to (a) investigate attentional functions of stimulant medication-naïve adults with ADHD, and (b) investigate the effects of 6 weeks of methylphenidate treatment on these functions.MethodsThe study was a prospective, non-randomized, non-blinded, 6-week follow-up design with 42 stimulant medication-naïve adult patients with ADHD, and 42 age and parental education-matched healthy controls. Assessments included measures of visual attention, based on Bundesen's Theory of Visual Attention (TVA), which yields five precise measures of aspects of visual attention; general psychopathology; ADHD symptoms; dyslexia screening; and estimates of IQ.ResultsAt baseline, significant differences were found between patients and controls on three attentional parameters: visual short-term memory capacity, threshold of conscious perception, and to a lesser extent visual processing speed. Secondary analyses revealed no significant correlations between TVA parameter estimates and severity of ADHD symptomatology. At follow-up, significant improvements were found specifically for visual processing speed; this improvement had a large effect size, and remained when controlling for re-test effects, IQ, and dyslexia screen performance. There were no significant correlations between changes in visual processing speed and changes in ADHD symptomatology.ConclusionsADHD in adults may be associated with deficits in three distinct aspects of visual attention. Improvements after 6 weeks of medication are seen specifically in visual processing speed, which could represent an improvement in alertness. Clinical symptoms and visual attentional deficits may represent separate aspects of ADHD in adults.

AimsAttention deficit hyperactivity disorder (ADHD) is a highly prevalent disorder in young adult prisoners. This audit aimed to identify how many residents are prescribed medication treatment for ADHD in HMP Elmley and whether those seen by the prison psychiatrists have been managed in line with NICE guidelines. We also audited waiting times and time to follow-up appointments. This was done with the overall aim to identify potential areas for development.MethodWe performed a spot audit of all residents in HMP Elmley who were prescribed ADHD medication on 4th November 2019, using their electronic patient records. Appointments with the psychiatrists were then subdivided into initial assessments and follow-up appointments for the purpose of analysis. Performance was measured against NICE Guideline [NG87]: Attention deficit hyperactivity disorder: diagnosis and management. We also calculated the waiting times for initial appointment and follow-up appointment.ResultWe found that 33 of residents were on ADHD medication at the time of the audit, approximately 3% of the prison population. 64% of those had a pre-existing diagnosis and 36% had been given a new diagnosis at HMP Elmley. Of those newly diagnosed 100% had undergone a Diagnostic Interview for Adults in ADHD (DIVA) assessment for diagnosis.Baseline physical health checks had been performed in 68% of patients prior to starting medication and a cardiovascular examination had occurred in 9%. At follow-up 100% of patients had their physical observations and weight checked and their symptoms reviewed.91% of patients were started on methylphenidate or lisdexamfetamine as first line treatment, with the rest started on atomoxetine and the reason for this documented.100% patients were offered general psychological support.There was a mean 22 day wait for an initial appointment (range 0-65) and a mean 20 day wait from starting medication to a psychiatric follow-up appointment (range 8-37)ConclusionThe number of residents treated for ADHD in HMP Elmley is relatively low (3%) compared to the estimated prevalence in prison population.The key areas for improvement are in baseline cardiovascular examinations and physical health evaluations. The waiting time between initial psychiatric appointment and follow-up is another area where improvement is needed and this will form the basis of a quality improvement project.Future steps include setting up a specific ADHD clinic with an allocated nurse practitioner to support, producing a template for ADHD assessments and follow-ups, producing a local policy on ADHD and developing specific resources for ADHD psychoeducation.
