The reported prevalence rates of psychiatric morbidity in the Indian industrial population range from 14-37%. 33, 34, FIG. Venlafaxine inhibits neuronal uptake of 5- HT (most potent, present at low doses), NA (moderate potency, present at high doses) and dopamine (DA) in order of decreasing potency. They also play a fundamental role in the structure and function of cells. 76 Polyamines can interact with several intracellular targets, including nucleic acids and enzymes, and exert several selective and complex actions on a variety of ion channels. Apprehension, Cognitive, Neurotransmitters, Glutamate, Serotonin etc, INTRODUCTION: Anxiety word was derived from the Latin root ‘anxieta’ meaning trouble in the mind about some uncertain event and it has a Greek root ‘anxo’ meaning to squeeze, strangle or press tight.

Though chemistry teachers might have to regularly field questions about the chemistry of ‘Breaking Bad’ these days, baking bread is probably more likely to figure on a list of their recreational activities. Chemistry just makes us understand how everything works a little better. Enzymes involved in the biosynthesis of these NASs, such as 5α- reductase and 3α-hydroxy-steroid oxidoreductase are found in key neuroanatomic structures involved in the anxiety such as the amygdala and the hippocampus. 6 Anxiety disorders are not considered as one disorder but these are a group of disorders characterized by persistent feelings of high anxiety, and extreme discomfort and tension. 134 Muscarinic M1 receptors induce anxiety through noradrenergic pathway. Henry G. Schwartzberg, Richard W. Hartel. 2002; 938(1-2): 81-6. 56 Each NMDAR complex consists of four (occasionally five) subunits: two NR1 subunits (generated by alternative splicing of a single gene, NR1), and two or three NR2 subunits (coded by four related genes, NR2 A–D). Food chemistry concepts are often drawn from rheology, theories of transport phenomena, physical and chemical thermodynamics, chemical bonds and interaction forces, quantum mechanics and reaction kinetics, biopolymer science, colloidal interactions, nucleation, glass transitions and freezing/disordered or noncrystalline solids, and thus has Food Physical Chemistry as a foundation area.[5][6].

Rubin MA, Stiegemeier JA, Volkweis MA, Oliveira DM, Fenili AC andBoemo RL: “Intra-amygdala spermidine administration improves inhibitory avoidance performance in rats”. 81-87, Polyamines (125–250 nmol, i.c.v.) Many studies suggest that glutamatergic neurotransmission of limbic system plays a pivotal role in the pathogenesis of anxiety disorders. 77, 78 Among them, especially remarkable is the dual modulation of a-amino-3-hydroxy- 5-methyl-4-isoxazole propionate (AMPA) 79 and N-methyl-D-aspartate (NMDA) receptors 80, which have been implicated in important plasticity events, such as learning and memory. Juergens, MD, Steven M:"Understanding Benzodiazepines". Cognitive component of anxiety is related to the cognitive distortions in the components of attention, interpretation, and memory for information processing. 102 Similarly, topiramate, an AMPA/ kainate blocker among other actions, was found in an open-label study to reduce re-experiencing symptoms in PTSD.
