Abstract:
Objective: This study evaluated the effects of dexmethylphenidate on problem behavior during functional analyses conducted across dexmethylphenidate and placebo conditions for a child with multiple disabilities. Methods: We conducted functional analyses in a multielement format embedded in a withdrawal design and collected data on the frequency of disruptive behavior and duration of crying. Results: Results suggest disruptive behaviour was maintained by attention when DMPH was absent, but not when it was present. Results also suggest DMPH may have had collateral effects on the probability of non-targeted behaviour (crying). Consistent with previous research, functional analyses exhibited a change in disruptive behaviour's function between medication and placebo conditions. Conclusion: These findings provide further support that stimulant medication may change the function of disruptive behavior and highlight the need to investigate the effects of stimulants on non-targeted behaviors.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
Target Cell Response to Hormones
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
