OBJECTIVE Children born very preterm (VP; <32 weeks) are at risk for attention deficit/hyperactivity disorders (ADHD). ADHD in VP children have a different clinical presentation to ADHD in the general population, and therefore VP children with difficulties may not come to the teacher's attention in school. We have assessed ADHD symptoms to determine whether VP children's difficulties may go und...

Introduction There are animal models associating dopamine dysfunction with behavioral impairments that model attention deficit hyperactivity disorder (ADHD). Erythropoietin (EPO) has trophic effects on dopaminergic neurons. Objectives The aim of this study was to examine the plasma levels and determine whether there any correlation between EPO clinical characteristics Attention-Deficit/Hyperact...

Abstract INTRODUCTION This study aimed to understand how ASD symptoms may relate different sleep problems. METHODS 128 parents of children with aged 4-14 participated in an anonymous survey. Parents completed the Short Sensory Profile (SSP), Children Sleep Habits Questionnaire (CSHQ), Strengths and Weaknesses Attention-Deficit/Hyperactivity-symptoms Normal-behaviours (SWAN) Revised Child Anxiet...

Muscle hyperactivity can manifest as involuntary twitches of muscle fibers or muscle groups or, more rarely, as a long lasting spasm. Clinically evident muscle hyperactivity must be considered abnormal only when it is consistent. Occasional involuntary twitches such as those experienced in the eyelids or in other muscles are probably only reflecting transient states of general stress or nervous...

In previous studies, we reported that a single afterdischarge (AD) or repeated ADs (kindling) in the hippocampus resulted in schizophrenia-like behaviors such as hyperactivity and loss of sensorimotor gating. Given that medial prefrontal cortex (PFC) dysfunction is also found in models of schizophrenia, we hypothesized that a single AD in the PFC induces postictal hyperactivity, and PFC kindlin...

OBJECTIVE Approximately 4.4 million (7.8%) children in the United States have been diagnosed with attention-deficit/hyperactivity disorder, and 56% of affected children take prescription medications to treat the disorder. Attention-deficit/hyperactivity disorder is strongly linked with low academic achievement, but the association between medication use and academic achievement in school settin...

Background: Attention deficit hyperactivity disorder (ADHD) is one of the most frequent behavioral disorders diagnosed in childhood, causing damage to child's neurocognitive development.

Cisplatin causes both acute and chronic forms of tinnitus as well as increases in spontaneous neural activity (hyperactivity) in the dorsal cochlear nucleus (DCN) of hamsters. It has been hypothesized that the induction of hyperactivity in the DCN may be a consequence of cisplatin's effects on cochlear outer hair cells (OHCs); however, systematic studies testing this hypothesis have yet to appe...

objective: early recognition of negative emotions is considered to be of vital importance. it seems that children with attention deficit hyperactivity disorder have some difficulties recognizing facial emotional expressions, especially negative ones. this study investigated the preference of children with attention deficit hyperactivity disorder for negative (angry, sad) facial expressions comp...
