Chronotype and its relationship with sleep disorders in children with attention deficit hyperactivity disorder.

Chronotype can be classified as morningness types, people who prefer morning hours for their physical and mental activities; eveningness types, people who prefer the afternoon or evening hours; and intermediate types, those who show characteristics of both morningness and eveningness types. Attention deficit hyperactivity disorder (ADHD) has been linked with disturbances in chronotype, particularly increased eveningness. Despite the possibility of an association between chronotypes, sleep disturbances and ADHD symptoms, there is little evidence of this association considering the child population.

The phenomenology of autistic regression: subtypes and associated factors.

This study aimed to investigate the association of autistic regression (AR) and subtypes of AR with medical, developmental and psychiatric factors. Fifty-seven children with autistic spectrum disorders (ASD) were included in the study. Two types of AR are defined as regression after a normal social/language development (type 1) and regression as the worsening of previously reported autistic features (type 2).

Cognitive and psychosocial development in children with familial hypomagnesaemia.

Aim: Familial hypomagnesaemia (FH) is a rare genetic condition. Neuromuscular and cardiovascular manifestations are well described, whereas cognitive and psychosocial development of children with FH is generally overlooked.

Methods: Nine patients with FH were evaluated with psychiatric examination and psychometric tests for cognitive and psychosocial outcome.

Association of sleep duration with socio-economic status and behavioural problems among schoolchildren.

Aim: In this population-based study, we aimed to determine the total sleep duration (TSD), its association with socio-economic status (SES) and behavioural symptoms among schoolchildren.

Methods: A cross-sectional study was performed among schoolchildren in Istanbul. A structured questionnaire evaluating the sleep schedule variables was filled out by their parents.

EEG abnormalities and epilepsy in autistic spectrum disorders: clinical and familial correlates.

Our aim was to examine the characteristics of EEG findings and epilepsy in autistic spectrum disorders (ASD) and the associated clinical and familial risk factors. Fifty-seven children (86% male) with ASD, mean age 82+/-36.2 months, were included in the study.

The prevalence of headache and its association with socioeconomic status among schoolchildren in istanbul, Turkey.

Objective: The etiology and pathogenesis of migraine and other types of headache are still under discussion. An interaction of organic, psychological, and psychosocial factors is operative. In this study, we aimed to determine the prevalence of headache and its association with socioeconomic status among schoolchildren.

Prevalence of headache and its association with sleep disorders in children.

An association between headache and sleep disturbances has been reported in previous studies, but there is a lack of research examining this relationship in a community sample of children in order to reveal the magnitude of the problem. Among 32 District Educational Directorates in Istanbul, nine school districts and within each district eight schools were randomly selected. A questionnaire consisting of sociodemographic variables and evaluating headache and sleep disturbances was sent to students' homes to be completed by their parents.

Prevalence of snoring and symptoms of sleep-disordered breathing in primary school children in istanbul.

Study Objectives: Snoring during sleep is an important manifestation of obstructive sleep apnea syndrome (OSAS). Although clinical history is not sufficiently sensitive and specific to distinguish primary snoring from OSAS, snoring is indicative of upper airway obstruction and may be associated with the presence of diurnal symptoms. Our study aims were to determine the prevalence of snoring in primary school children in Istanbul, and to evaluate the diurnal symptoms and conditions that may be associated with sleep problems.
