Description

Guanfacine is an alpha-2 adrenergic receptor agonist used to treat attention deficit hyperactivity disorder (ADHD) and high blood pressure. It is synthesized through a series of chemical reactions starting with a substituted phenylethylamine derivative. Guanfacine works by stimulating alpha-2 receptors in the brain, which leads to decreased norepinephrine release. This action helps to improve focus and attention in individuals with ADHD, and also helps to reduce blood pressure. Guanfacine is an important medication for managing ADHD and high blood pressure, and it is studied extensively to understand its mechanisms of action, efficacy, and potential side effects. It is a valuable tool for treating these conditions and improving the lives of affected individuals.'

Effects

Guanfacine has been approved by the Food and Drug Administration (FDA) to treat hypertension and conduct disorder, but as it reduces body weight, it is worth examining its effectiveness and safety in models of obesity. Guanfacine can reverse a depression-like state induced by increased acetylcholine (ACh) signaling.

Change From Baseline in Choice Reaction Time (CRT) at 6 Weeks

Choice reaction time (CRT) is a computerized assessment that trains the subject in holding down a press-pad and releasing the press-pad in response to stimuli presented on the screen. The task requires the subject to react as soon as a yellow dot appears in one of five locations, and the subject must respond by lifting their hand from the press-pad. This is the reaction time (RT) and ranges from 100 to 5000 msec. Lower scores indicate better performance. (NCT00150592)

Change From Baseline in Spatial Working Memory (SWM) Scores at 6 Weeks

"The Spatial Working Memory (SWM) Test is a computerized assessment of working memory and strategy performance. The subject is required to find blue tokens in various displayed boxes and use the tokens to fill a column on the right side of the screen. Subjects can only find tokens in new boxes, therefore they must remember where previous tokens were found. SWM scores including number of between errors, number of within errors, and number of double errors range 0-800 and SWM strategy scores range 8-56. Lower scores indicate better performance."

"Touchscreen Cancellation: This is a computerised scale for measuring the severity of spatial neglect as described in previous publications (Malhotra et al, Annals of Neurology 2006; Parton et al, Neuroreport 2006). Patients are asked to find and touch targets (which are embedded amongst distractors) on a touchscreen. In the variant of the task employed here, the targets are not marked when touched (Invisible Cancellation).The maximum number of targets that can be found is 64 (Therefore minimum score =0, maximum = 64), which represents normal performance."

Dynamic Indicators of Basic Early Literacy Skills Oral Reading Fluency Subtest (DIBELS ORF)

DIBELS ORF measures oral reading fluency in connected text. Students are presented with a passage on their grade level to read orally, and the score is the number of words of the passage read correctly in a one-minute period. Students in this study read two passages at each test administration, and the mean score for the two passages was the dependent variable analyzed. A research synthesis of studies reporting psychometric properties for DIBELS ORF determined that reliability coefficients in these studies exceeded .80 and that the measure demonstrated moderate to high concurrent and predictive validity across studies (Goffreda & DiPerna, 2010).

ADHD Rating Scale - Hyperactivity Subscale

The ADHD Rating Scale (ADHD-RS) is an 18-item scale directly derived from DSM-IV criteria for Attention Deficit Hyperactivity Disorder with established reliability, validity and sensitivity to change. The ADHD Rating Scale-IV is completed independently by the parent and scored by a clinician. The scale consists of 2 subscales: inattention (9 items) and hyperactivity-impulsivity (9 items). If 3 or more items are skipped, the clinician should use extreme caution in interpreting the scale. Results from this rating scale alone should not be used to make a diagnosis. This subscale can range from 0 to 27 for scoring,with a higher score indicating greater severity. (NCT01238575)

Yale Global Tic Severity Scale (YGTSS)

The YGTSS is a clinician-rated scale that begins with a systematic inquiry of tic symptoms in the preceding week. Current motor and phonic tics are rated separately according to number, frequency, intensity, complexity, and interference, each rated on 0 to 5 scale with higher scores indicating greater severity/worse outcome (Leckman et al. 1989). The YGTSS yields a total motor score (0-25), a total phonic score (0-25), a total tic score (sum of total motor and total phonic scores; 0-50), and an impairment score (0-50). Higher scores indicate greater severity/worse outcome. (NCT01547000)

Digit Span

Neuropsychological assessment - Digit Span. The Digit Span test is either conducted verbally or using a computer program. A sequence of numbers is shown or read out to the participant. The participant is then told to repeat the numbers that were shown or read to them. This process continues until the participant can no longer remember either the full sequence of numbers or the correct order. This sequence is also continued until the participant makes an error. The Digit Span test is scored by the amount of numbers the participant was able to remember in each test. The scorer must add the total number of correct sequences, backwards and forwards. This test is also scored differently for a range of ages. (NCT01709695)

Number of Participants That Were Responders

Overall response to treatment is defined as at least a 70% decline in both the Modified Overt Aggression Scale (MOAS) score and the Symptom Checklist-6 (SCL-6) from randomization to end of study. The MOAS measures the severity of explosive overt aggression. The score can range from 0 (no overt aggressive) and it has no theoretical upper limit (incidents could be too many to count). The higher the score, the more serious the aggression; the lower the score, the less serious the aggression. Response to treatment is defined as a 70% or more reduction in the MOAS at the end of the study. The SCL-6 uses 6 subscale items from the larger SCL that measure hostility or irritability on a scale of 1 (not at all) - 5 (definitely). The raw score ranges from 6 (no irritability) to 30 (severe irritability). The lower the score is, the better the outcome. The % decline vary from 0%-100%. A 70% or more decline in the SCL-6 score at the end of study is a response. (NCT02048241)
