Previous research on developmental dyscalculia (DD) suggested that deficits in the number line estimation task are related to a failure to represent number magnitude linearly. This conclusion was derived from the observation of logarithmically shaped estimation patterns. However, recent research questioned this idea of an isomorphic relationship between estimation patterns and number magnitude ...

Piaget's genetic epistemology has provided the constructivist approach upon which child developmental theories were founded, in that infants are thought to progress through distinct cognitive stages until they reach maturity in their early 20's. However, it is now well established that cognition continues to develop after early adulthood, and several "neo-Piagetian" theories have emerged in an ...

Advances in defining mechanisms of cortical development have been paralleled in recent years by an intense interest in translating these findings into greater insight of both childhood- and adult-onset cognitive and mental health disorders of developmental etiology. Successful integration of basic and clinical findings have been applied to monogenic disorders. The greater challenge lies in stud...

Attention-deficit/hyperactivity disorder (ADHD) is a clinically important neuropsychiatric developmental disorder that affects children, adolescents, and adults. The disorder is characterized by core symptoms of inattention, hyperactivity, distractibility, impulsivity, and impaired executive functioning. It is estimated that 2% to 5% of the adult population in the United States has ADHD. Adults...

Cerebellar abnormalities have been linked to a number of developmental disorders. Much evidence is based on the analysis of high-resolution MRI scans. Imaging and behavioral studies have led researchers to consider functional contributions of the cerebellum beyond that associated with motor control. I review this literature, providing an analysis of different ways to consider the relation betwe...

STUDY OBJECTIVES The objective of this study was to determine if primary care providers (PCPs) screen for sleep disorders during clinical evaluation of new patients, and to compare this to likely sleep diagnoses as assessed by validated questionnaires. METHODS Adult patients evaluated as new patients in a primary care clinic at a tertiary care center were included in a prospective study. Foll...

It was considered that neurogenesis only occurred during the embryonic and developmental stage. This view has greatly changed since the discovery of adult neurogenesis in two brain regions: the hippocampus and the olfactory bulb. Recently, it is suggested that altered hippocampal neurogenesis is related to pathophysiology of mood disorders and mechanism of antidepressant treatments. Accumulatin...

Pharyngitis and tonsillitis, regardless of their aetiology, are one the most frequent reasons for visiting a family doctor or paediatrician. Nearly 85% pharyngitis cases viral. It is estimated that bacterial throat infection occurs in 15% schoolage children 4–10% adult patients. Streptococcus pyogenes common cause pharyngitis. PANDAS stands paediatric autoimmune neuropsychiatric disorders assoc...
