depression, puberty, cognitive development

D Purper-Ouakil, A Didillon
INTRODUCTION: Puberty is a developmental process characterized by hormonal and physical changes leading to the ability of reproduction. Precocious puberty, especially in girls, has been associated with an increased incidence of emotional and behavioral problems. Adolescence is a life stage influenced both by the biological changes of puberty and the emergence of new social challenges. In individuals facing these developmental issues at a younger age than expected, the exposure to internal and external stress factors may be greater than in other young people...

IMPORTANCE: The trajectory of cortical gray matter development in childhood has been characterized by early neurogenesis and volume increase, peaking at puberty followed by selective elimination and myelination, resulting in volume loss and thinning. This inverted U-shaped trajectory, as well as cortical thickness, has been associated with cognitive and emotional function. Synaptic pruning-based volume decline has been related to experience-dependent plasticity in animals. To date, there have been no data to inform whether and how childhood depression might be associated with this trajectory...

BACKGROUND: Teen suicide is a major public health problem. In the United States, it is the third cause of death among the 10-24 year olds. Adolescence involves numerous changes, whether physical, social, emotional or hormonal. At a neurobiological level, a teenager's nervous system is also affected and undergoes significant modifications. SUBJECTS AND METHODS: We conducted a systematic review of electronic literature published between January 1990 and August 2014 via MEDLINE, PubMED and PsychINFO to list articles concerning the risk of teen depression and suicide risks in adolescents as well as those relating to the adolescent's neuro-anatomical brain and the effect that puberty has on it...

Puberty and adolescence are major life transitions during which an individual's physiology and behavior changes from that of a juvenile to that of an adult. Here we review studies documenting the effects of stressors during pubertal and adolescent development on the adult brain and behavior. The experience of complex or compound stressors during puberty/adolescence generally increases stress reactivity, increases anxiety and depression, and decreases cognitive performance in adulthood. These behavioral changes correlate with decreased hippocampal volumes and alterations in neural plasticity...

This is a report on the research design and findings of a 23-year longitudinal study of the impact of intrafamilial sexual abuse on female development. The conceptual framework integrated concepts of psychological adjustment with theory regarding how psychobiological factors might impact development. Participants included 6- to 16-year-old females with substantiated sexual abuse and a demographically similar comparison group. A cross-sequential design was used and six assessments have taken place, with participants at median age 11 at the first assessment and median age 25 at the sixth assessment...

The purpose of the study is to assess the relationship between timing of adolescent development and risk factors for suicide. Nationally representative data from the Add Health survey were used. The relationship of sociodemographic characteristics, known risk factors, and physical developmental timing and cognitive developmental style to suicide attempt was assessed. Depression was a risk factor for suicide attempts in both 9th and 11th grade. Other risk factors differed. Use of illegal drugs, homosexual orientation, using public assistance, and physical development were the important risk factors for ninth graders...

Executive functions and social cognition develop through childhood into adolescence and early adulthood and are important for adaptive goal-oriented behavior (Apperly, Samson, & Humphreys, 2009; Blakemore & Choudhury, 2006). These functions are attributed to frontal networks known to undergo protracted maturation into early adulthood (Barker, Andrade, Morton, Romanowski, & Bowles, 2010; Lebel, Walker, Leemans, Phillips, & Beaulieu, 2008), although social cognition functions are also associated with widely distributed networks...

Studies of puberty have focused primarily on changes in hormones and on observable physical bodily characteristics. Little is known, however, about the nature of the relation between pubertal status and brain physiology. This is particularly important given findings that have linked the onset of puberty with both changes in cognitive functioning and increases in the incidence of depression and anxiety. The present study examined relations between pubertal stage, as assessed by Tanner staging, and brain anatomy in a sample of 54 girls aged 9-15 years...

The rise in infantile autism, learning problems, cognitive decline with age, Alzheimer's, Parkinson's diseases and the SIDS epidemic, has a common cause in the rising dietary deficit in Omega-3 brain-food. This paper suggests that aside from the wider concept of autism spectrum disorders (ASD) and pervasive developmental disorders (PDD), the rise in infantile autism (IA) in the last decade is the effect of deficient brain-food (Omega-3). The consequent delay of development, prolongs the 2nd regressive event in infancy to pruning of the centre in the Medial Frontal Lobe System that connects hippocampus and singulum...

Chronic distress contributes to the development of obesity and comorbid states. Stress is the disturbance of the complex dynamic equilibrium that all organisms must maintain, and is associated with activation of the Stress system comprising of the hypothalamic-pituitary-adrenal axis and the arousal/sympathetic nervous systems. The stress system functions in a baseline circadian fashion and interacts with other systems of the organism to regulate a variety of behavioral, endocrine, metabolic, immune and cardiovascular functions...

The neuroendocrine theory of aging suggests the common mechanisms of developmental (prereproductive) and aging (postreproductive) processes and identified a cluster of conditions (hypertension, obesity, dyslipidemia, type 2 diabetes, menopause, late onset depression, vascular cognitive impairment, impairment of immune defense, and some forms of cancer) as age-associated neuroendocrine disorders (AAND). Obesity, dyslipidemia, hypertension, and type 2 diabetes were later described as metabolic syndrome (MetS)...

BACKGROUND: Lower cognitive functioning in early childhood has been proposed as a risk factor for depression in later life but its association with depressive symptoms during adolescence has rarely been investigated. Our study examines the relationship between total intelligence quotient (IQ) score at age 8 years, and depressive symptoms at 11, 13, 14 and 17 years. METHOD: Study participants were 5250 children and adolescents from the Avon Longitudinal Study of Parents and their Children (ALSPAC), UK, for whom longitudinal data on depressive symptoms were available...

Maternal alcohol consumption during critical periods of fetal brain development leads to devastating long-term consequences on adult reproductive physiology, cognitive function, and social behaviors. However, very little is known about the long-term consequences of alcohol consumption during puberty, which is perhaps an equally dynamic and critical period of brain development. Alcohol abuse during adulthood has been linked with an increase in clinically diagnosed anxiety disorders, yet the etiology and neurochemical mechanisms of alcohol-induced anxiety behavior is unknown...

Maturation of brain structure has a different rhythm in girls and boys. From the viewpoint of cognitive processes, the first decade of life is the most important developmental stage after intrauterine life, cognitive functions will essentially develop also during the second decade. Gender differences have been noted already in early adolescence. Behavioral disturbances and substance abuse problems as well as attention-deficit disorders are more common in boys, whereas depression, anxiety and eating disorders are more common in girls...

The distribution of Kraepelin's ubiquitous dichotomy varies with standard of living and pubertal age: when one rises, the other declines. The universal similar clinical picture--mortality risk, manic depressive psychosis, episodic dysfunction of brainstem control systems (sleep-wake cycle, food, mood control mechanism)--is caused by abridged pubertal pruning of excitatory synapses, which is treated with anti-epileptics, as opposed to convulsant neuroleptics in dementia praecox, where the clinical variation reflects varying degrees of excessive pruning and deficit in excitability...

BACKGROUND: Previous studies suggest that failure to thrive in infancy may be associated with adverse sequelae in childhood. Although cognitive abilities have been extensively investigated, little systematic research is available on other aspects of development. METHODS: Eighty-nine children who failed to thrive as infants and 91 controls were followed up when twelve years old and examined using anthropometric measurement, self-ratings of appetite and body image, the Dutch Eating Behaviour Questionnaire, the Self-perception Profile for Children, The Revised Children's Manifest Anxiety Scale, the parent and child form of the Mood and Feelings Questionnaire and the parent and teacher's form of the Child Behavior Checklist...

With optimal pregnancy conditions (natural, enriched diet which includes fish) African (Digo) infants are 3-4 weeks ahead of European/American infants in sensorimotor terms at birth, and during the first year. Infants of semi-aquatic sea-gypsies swim before they walk, and have superior visual acuity compared with us. With adverse pregnancy behaviour (fear of fat, a trend to dieting), neglecting the need for brain fat to secure normal brain development and function, we run a risk of dysfunction--death. Sudden Infant Death Syndrome victims have depressed birth weight, lower levels of marine fat in brainstem than controls, and >80 suffer multiple hypoxic episodes prior to death...

Stress activates the central and peripheral components of the stress system, i.e., the hypothalamic-pituitary-adrenal (HPA) axis and the arousal/sympathetic system. The principal effectors of the stress system are corticotropin-releasing hormone (CRH), arginine vasopressin, the proopiomelanocortin-derived peptides alpha-melanocyte-stimulating hormone and beta-endorphin, the glucocorticoids, and the catecholamines norepinephrine and epinephrine. Appropriate responsiveness of the stress system to stressors is a crucial prerequisite for a sense of well-being, adequate performance of tasks and positive social interactions...
