Using portable software installing in the mobile cell can help the clinicians to reduce the effects of confounders in emergency treatment of patients. Methods: This study was conducted in 2017 in the Department of Emergency, Rasoul-e Akram hospital, Tehran, Iran. After designing the management protocol for patients with vertigo based on the literature and standards, the validity of the protocol was approved by the expert panel. A number of 190 patients with vertigo were diagnosed using two methods for treatment and management of the disease. The first group were assessed using designed clinical decision support system, and the second group were assessed using routine method. Treatment duration, maintenance duration, and the differences between the primary and the final diagnosis were compared between the groups. Findings: Differences between the primary and the final diagnosis were sign...

This disorder is related to learning difficulties despite normal intelligence and proper instructions at home and school. Delay in identification and intervention of dyslexia will affect the person's future. The aim of the present study was designing a neuro-cognitive program for measurement and evaluation of working memory, in order to screen and detect preschoolers with different function in the early stages. Materials and Methods: The neuro-cognitive program was designed with C-Sharp software based on neuro-cognitive theories, especially information processing theory. To define the output or making the intelligent program, the data and functions of the children with definite diagnosis, dyslexia or without the disorder, were needed. Thus, a total of 256 children were selected with cluster random sampling method and their scores and data ...

The visual and auditory working memories in pre-schoolers were evaluated with this program in order to early screening for dyslexia. Methods: This study is a longitudinal descriptive research. A total of 259 randomly selected pre-schoolers, with an average age of 6 years, participated in the study and the unskilled data of these students were gathered. These subjects were followed for two years. Thereafter, the remaining subjects were assessed accurately for dyslexia using different reading diagnostic tests. Then, the preschool unskilled data and the diagnosis were applied to automate the designed program. The program was designed in a game format and consisted of separate tasks measuring visual and auditory working memories and rapid naming. Results: From the calculation of content validity rate as the first step of content validity process, 3 out of 5 components, including visual and auditory working memories, and rapid naming were selected. The process and the results of content validity showed that the designed program has an appropriate and acceptable level of content validity. The amount of reliability of the program for visual and auditory working memories, and rapid naming were obtained as 0.89, 0.92 and 0.88, respectively. Moreover, the discriminative validity for auditory and visual working memories and rapid naming, between children with dyslexia, Attention Deficit Hyperactivity Disorder (ADHD) (a disorder having high similarity with dyslexia) and normal ones were obtained as 0.87, 0.67 and 0.8, respectively. It is worthy to say that the prediction accuracy of this neuro-cognitive program for dyslexia achieved 90.65%. Discussion: This program has an acceptable validity and reliability. It could be useful as an accurate assessment tool in predicting dyslexia before the occurrence of psychological scars and can be used as a quick screening tool for children at risk for dyslexia.

Twenty-four students participated as test and control groups. The auditory and visual–spatial WM were assessed by primary test, which included computerised Wechsler numerical forward and backward sub-tests and secondary tests, which contained three parts: dual visual–spatial test, auditory test and a one-syllable word recalling test. The results showed significant difference between WM capacity in the intellectually disabled children and normal ones (p-value We found that school is the best place for training. More comprehensive human–computer interfaces could be suitable for intellectually disabled students with visual and auditory impairments and problems in motor skills.

More than 99% of the individuals with DS have an extra copy of the entire chromosome 21. Generally they have a set of mental traits such as behavioral and cognitive deficits, learning disabilities, delay in speech and language skills and in working memory, delays in gross and fine motor skills and many other features. Short-term memory performances, long-term memory and visuoperceptual abilities are impaired because of dysfunction of different parts of the brain. Overall, studies show a deficient brain organization in DS. One of the main goals of training in DS, is improving skills (such as: attention, perception, counting, obeying rules, and communication) for adult life. Sensory integration, neurodevelopmental therapy and vestibular stimulation are some effective rehabilitation methods for DS children but one of the most important problems during DS rehabilitation process is the lack of motivation of these children that interferes the process of education and rehabilitation. It was proved that using Virtual Reality (VR) technology, an immersive interactive three-dimensional (3D) computer environment, can improve motivation and self efficacy of disabled children such as cerebral palsy (CP). This technology improved motor performances and mobility skills, promoted learning, and increased visual perception and executive functions in such cases. Computer has been used to improve social communications in DS, but no study has been done on the effect of VR in rehabilitation of this syndrome. We suggest using virtual reality technology for educating and rehabilitating of DS children besides traditional methods. This colorful environment would be fantastic for DS children. Moreover, the education and rehabilitation could be adjusted to the needs and abilities of each person. The complexity and the degree of exposure to the multiple stimuli could be increased gradually, based onmotivation and cooperation of the patient. It must be noted that the educational program in this space could be like a game. Surely, experimental studies are needed to verify our hypothesis about the effectiveness of VR in DS.

In this study, we tried to differentiate and classify (diagnose) 306 children with many similar symptoms and different behavioral disorders such as ADHD, depression, anxiety, comorbid depression and anxiety and conduct disorder with high accuracy. Classification was based on the symptoms and their severity. With examining 16 different available classifiers, by using "Prtools", we have proposed nearest mean classifier as the most accurate classifier with 96.92% accuracy in this research.

Accuracy of classifying with Radial basis function and multilayer neural networks were compared. Finally, the average accuracy of the networks in classification reached to 95.50% and 96.62% by multilayer and radial basis function networks respectively. Our results indicate that a decision support system, especially RBF, may be a good preliminary assistant for psychiatrists in diagnosing high risk behavioral disorders of children.
