Novel behavioural and molecular determinants and indicators of attention deficit-/hyperactivity disorder in adults. / Alison Louise Baird

Swansea University Author: Alison Louise Baird

Abstract

Attention deficit-/hyperactivity disorder (ADHD) is a psychiatric condition that can affect both children and adults. It is characterised by behavioural and attention difficulties. Sleep deficits are a prominent characteristic of the disorder and some of the core symptoms of ADHD are known character...

description Attention deficit-/hyperactivity disorder (ADHD) is a psychiatric condition that can affect both children and adults. It is characterised by behavioural and attention difficulties. Sleep deficits are a prominent characteristic of the disorder and some of the core symptoms of ADHD are known characteristics of sleep deprivation. The circadian clock is integral to determining the rhythm of the sleep/wake cycle.

Secondly to address how circadian clock functioning may be disturbed in adult ADHD via measurement of a number of molecular, endocrine and behavioural markers, for which real-time RT-PCR, ELISA and actigraphy techniques were employed. Thirdly to examine the effects of ADHD medication upon circadian clock protein expression in the rodent brain using immunohistochemistry methods.Here it is demonstrated that disturbances in the rhythmic secretion of endocrine factors that are key outputs and regulators of the master circadian pacemaker, the circadian clock gene expression of a peripheral oscillator and the actigraphic measures of circadian organization of gross behaviour are associated with adult ADHD.
