Anxiety disorders are chronic, disabling conditions that are distributed across the globe. Woefully, the consistent increase of prevalence rate had affected people across nations range from children to adults. Biological attributed risk factors had associated strongly with the early onset of anxiety during the childhood stage. This current research intended to study the biological risk factors of brain electrical activity, hereditary and gender effect on trait anxiety among anxious children. A total of 36 children, aged ranged from 8 to 13 years old with high trait anxiety level were recruited by using a purposive sampling method. Self- administered STAIC-T and STAIT were used to measure the trait anxiety level of children and parents respectively. Besides, neuroimaging of Quantitative Electroencephalogram (qEEG) brain mapping was administered to study the brain electrical activity and associated brain locations. Pearson’s Correlation was carried out in order to study the relationship between biological risk factors with trait anxiety level. Results showed that there is a significant relationship between parents’ trait anxiety score and children’s trait anxiety score. Preliminary findings indicated that the brain locations of Fp1, F4, F8, T3, and T4 showed a significant relationship with trait anxiety. In conclusion, hereditary and associated brain locations played a role in affecting the trait anxiety level of children and results in the biological vulnerability of anxiety since birth.

AbstractSeasonal affective disorder (SAD) is characterized by recurrent depression occurring generally in fall/winter. Numerous pieces of evidence indicate the association of SAD with decreased brain neurotransmitter serotonin (5-HT) system functioning. Tryptophan hydroxylase 2 (TPH2) is the key and rate-limiting enzyme in 5-HT synthesis in the brain. This paper concentrates on the relationship between TPH2 activity and mood disturbances, the association between human

Levels of vasopressin, somatostatin, neurotensin, vasoactive intestinal peptide, corticotrophin-releasing factor and adrenocorticotrophin in CSF were determined in lithium-treated and unmedicated euthymic bipolar patients and controls, in a search for a trait marker in affective disorder. No group differences in levels of these peptides were found. Highly significant positive correlations were found among these peptides (with the exception of neurotensin), suggesting that their presence in CSF is functionally significant, as opposed to the result of random diffusion from the interstitial space of the brain.

The title of this review would be regarded by some psychiatrists as provocative; they would relegate the biochemical concomitants of depression and mania to a secondary position and deny that biochemical changes have any place in the aetiology of these conditions. However, in my view, the weight of evidence, although it is by no means conclusive, suggests that biochemical changes are most important in the aetiology of affective disorders. A biochemical aetiology implies that there are certain biochemical changes in the brain which need to be restored to normal before the patient's clinical condition will improve. This does not deny that psychological and environmental events may precipitate and maintain the biochemical events which in turn lead to the affective disorder. The study of these biochemical events is clearly at too early a stage for speculations about the interrelationship between environmental and endogenous elements to be fruitful; this study must wait until the biochemical aetiology is clearer than at present.

The amine theory of affective disorder and the dopamine and endorphin theories of schizophrenia are controversial but heuristically valuable concepts that have emerged from the psychobiological revolution of the last decade. That revolution stemmed largely from the development of techniques for localizing and assaying neuroregulators and their receptors in the brain under normal, pathological and experimental conditions. The data thus obtained are reviewed here, and the current status of the emergent psychobiological hypotheses assessed.
