چکیده

The prefrontal cortex (PFC) is among the most evolved brain regions, contributing to our highest order cognitive abilities. It regulates behavior, thought, and emotion using working memory. Many cognitive disorders involve impairments of the PFC. A century of discoveries at Yale Medical School has revealed the neurobiology of PFC cognitive functions, as well as the molecular needs of these circuits. This work has led to the identification of therapeutic targets to treat cognitive disorders. Recent research has found that the noradrenergic α2A agonist guanfacine can improve PFC function by strengthening PFC network connections via inhibition of cAMP-potassium channel signaling in postsynaptic spines. Guanfacine is now being used to treat a variety of PFC cognitive disorders, including Tourette's Syndrome and Attention Deficit Hyperactivity Disorder (ADHD). This article reviews the history of Yale discoveries on the neurobiology of PFC working memory function and the identification of guanfacine for treating cognitive disorders.

Reducing the Harm of Stress: Medications to Rescue the Prefrontal Cortex and Overcome Bad Habits

Our brain is sensitive to stress. Both acute and chronic stress cause cognitive deficits and induce chronic disorders such as drug addiction. In a June 2011 conference at Yale entitled "The Science of Stress: Focus on the Brain, Breaking Bad Habits, and Chronic Disease," Drs. Amy Arnsten and Sherry Mckee discussed the roles of prefrontal cortex in the treatment of stress impairments and addicti...

The Therapeutic Effect of Electroconvulsive Therapy in Obsessive-Compulsive Disorder Patients: A Quasi-Experimental Study

Background: Electroconvulsive therapy (ECT) is demonstrated to be an effective treatment in some psychiatric disorders. It is postulated ECT should primarily be considered for patients with treatment-resistant obsessive-compulsive disorder (OCD) in the context of major depression. Therefore, we aimed to evaluate the efficacy of ECT in OCD patients without comorbid psychiatric disorders. Method...

Introduction: new developments in the treatment of attention-deficit/hyperactivity disorder.

Guanfacine Guanfacine, an α2-adrenergic receptor agonist, has had mixed results in the treatment of ADHD. Although guanfacine has been shown to have cognitive-enhancing properties, in a recent study of its effect on executive function and memory, 60 healthy males were randomly assigned guanfacine in double-blind fashion at a single dose of 1 mg, 2 mg, or placebo. No statistically significant ef...

Cognitive Effects of Stimulant, Guanfacine, and Combined Treatment in Child and Adolescent Attention-Deficit/Hyperactivity Disorder.

OBJECTIVE Psychostimulants are partially effective in reducing cognitive dysfunction associated with attention-deficit/hyperactivity disorder (ADHD). Cognitive effects of guanfacine, an alternative treatment, are poorly understood. Given its distinct action on α2A receptors, guanfacine may have different or complementary effects relative to stimulants. This study tested stimulant and guanfacine...
