BACKGROUND/OBJECTIVES: Nuclear peroxisome proliferator activated receptor-α (PPAR-α) plays a fundamental role in the regulation of lipid homeostasis and is the target of medications used to treat dyslipidemia. However, little is known about the role of PPAR-α in mouse behavior. METHODS: To investigate the function of Ppar-α in cognitive functions, a behavioral phenotype analysis of mice with a targeted genetic disruption of Ppar-α was performed in combination with neuroanatomical, biochemical and pharmacological manipulations...

Drug addiction is a chronic disorder characterized by a cycle composed of drug seeking, intoxication with drug taking and withdrawal associated with negative affect. Numerous studies have examined withdrawal/negative affect after chronic use; however, very few have examined the effect of acute administration on the negative affective state after acute drug withdrawal. One dose of amphetamine was injected into Sprague-Dawley rats. Despair behavior using the modified forced swim test (FST) and dopamine (DA) activity in the ventral tegmental area using in vivo electrophysiological recordings were studied 18, 48 and 72 h after injection of amphetamine...

The links between attention-deficit hyperactivity disorder (ADHD) and sleep disorders remain unclear. Specific sleep disorders are a frequent comorbid condition associated with ADHD according to a categorical approach. However, sleep disorders can also induce ADHD-like symptoms according to a dimensional approach and are thought to be the consequence of excessive daytime sleepiness. It may thus be difficult for clinicians to differentiate the diagnosis of ADHD comorbid with a sleep disorder from sleep disorders with ADHD-like symptoms...

The current study examined attention-deficit/hyperactivity disorder (ADHD) and anxiety symptoms in relation to self-reported executive functioning deficits in emerging adults. College students (N = 421; ages 17-25; 73.1% female) completed self-reports of ADHD, anxiety, and executive functioning in a laboratory setting. Structural equation modeling analyses revealed that self-reported executive functioning deficits were significantly related to all 3 symptom domains. Executive functioning deficits were most strongly related to inattention followed by hyperactivity/impulsivity and anxiety...

BACKGROUND: Rats emit 50 kHz ultrasonic vocalizations (USVs) in response to either natural or pharmacological pleasurable stimuli, and these USVs have emerged as a new behavioral measure for investigating the motivational properties of drugs. Earlier studies have indicated that activation of the dopaminergic system is critically involved in 50 kHz USV emissions. However, evidence also exists that non-dopaminergic neurotransmitters participate in this behavioral response. METHODS: To ascertain whether glutamate transmission plays a role in 50 kHz USV emissions stimulated by amphetamine, rats received five amphetamine (1-2mg/kg, i...

Attention deficit/ hyperactivity disorder (ADHD) is a heritable neurodevelopmental disorder featuring complex genetics with common and rare variants contributing to disease risk. In a high proportion of cases, ADHD does not remit during adolescence but persists into adulthood. Several studies suggest that NOS1, encoding nitric oxide synthase I, producing the gaseous neurotransmitter NO, is a candidate gene for (adult) ADHD. We here extended our analysis by increasing the original sample, adding two further samples from Norway and Spain, and conducted subgroup and co-morbidity analysis...

Parkinson disease (PD) is a neurodegenerative disorder characterized by massive loss of midbrain dopaminergic neurons. Whereas onset of motor impairments reflects a rather advanced stage of the disorder, hyposmia often marks the beginning of the disease. Little is known about the role of the nigro-striatal system in olfaction under physiological conditions and the anatomical basis of hyposmia in PD. Yet, the early occurrence of olfactory dysfunction implies that pathogens such as environmental toxins could incite the disease via the olfactory system...

Repeated exposure to psychostimulant drugs such as cocaine or amphetamine can promote drug-seeking and -taking behavior. In rodent addiction models, persistent changes in excitatory glutamatergic neurotransmission in the nucleus accumbens (NAc) appear to drive this drug-induced behavioral plasticity. To study whether changes in glutamatergic signaling are shared between or exclusive to specific psychostimulant drugs, we examined synaptic transmission from mice following repeated amphetamine or cocaine administration...

A deficit in "interference control" is commonly found in adults with Attention Deficit Hyperactivity Disorder (ADHD). This has mainly been interpreted as difficulties in inhibiting inappropriate responses. However, interference control involves processes other than simply the ability to inhibit. Consequently, we used sophisticated analysis to decipher the additional processes of interference control in these patients. We compared interference control between 16 adults with ADHD and 15 control adults performing a Simon task...

BACKGROUND: Children with attention deficit hyperactivity disorder (ADHD) experience significant ongoing social difficulties which occur in multiple contexts. Interventions designed to improve these social difficulties have demonstrated minimal effectiveness. Thus, there is a clear need to establish interventions that are effective in addressing the social difficulties of children with ADHD across contexts and in the long term. AIM: To examine the long-term effectiveness and appropriateness of a pilot parent-delivered intervention designed to improve the social play skills of children with ADHD and their playmates...

Borderline personality disorder (BPD) and attention-deficit-hyperactivity disorder (ADHD) are both characterized by high impulsivity and difficulties in controlling anger and aggression. In BPD, comorbid ADHD may further increase impulsivity. For both disorders, altered MR spectroscopy levels of the neurotransmitters glutamate and GABA as well as some correlations with impulsivity were previously reported. The objective of this study was to investigate the neurotransmitters glutamate and GABA in relation to impulsivity and aggression as expressed in the anterior cingulate cortex (ACC) in groups of female patients with BPD and ADHD, respectively...

REVIEW
David Williamson, Charlotte Johnston
Certain characteristics of attention-deficit/hyperactivity disorder (ADHD) in children have long been known to differ by gender. What has not been as widely studied is whether gender is similarly associated with ADHD differences in adults. In this review, the relation between gender and adult ADHD prevalence, persistence, impairment, comorbidity, cognitive functioning, and treatment response was examined across 73 studies. Although gender was related to several characteristics and correlates of adult ADHD, it appeared that many of these gender differences may be at least be partially attributed to methodological artifacts or social and cultural influences, rather than fundamental differences in the expression of ADHD in men and women...

RATIONALE: Obesity is a leading public health problem worldwide. Multiple lines of evidence associate deficits in the brain reward circuit with obesity. OBJECTIVE: Whether alterations in brain reward sensitivity precede or are a consequence of obesity is unknown. This study aimed to investigate both innate and obesity-induced differences in the sensitivity to the effects of an indirect dopaminergic agonist. METHODS: Rats genetically prone to diet-induced obesity (DIO) and their counterpart diet-resistant (DR) were fed a chow diet, and their response to D-amphetamine on intracranial self-stimulation and food intake were assessed...

Individuals with attention deficit/hyperactivity disorder (ADHD) are at increased risk of developing substance use disorders (SUDs) and nicotine dependence. The co-occurrence of ADHD and SUDs/nicotine dependence may in part be mediated by shared genetic liability. Several neurobiological pathways have been implicated in both ADHD and SUDs, including dopamine and serotonin pathways. We hypothesized that variations in dopamine and serotonin neurotransmission genes were involved in the genetic liability to develop SUDs/nicotine dependence in ADHD...

AIM: Previous studies have shown an association between childhood attention deficit hyperactivity disorder (ADHD) and a down-regulated hypothalamus-pituitary-adrenal axis (HPA axis) with low diurnal cortisol levels. Given the role of the FK506 binding protein 5 (FKBP5) as an important regulator of the negative feedback system of the HPA axis, we set out to investigate possible associations between single nucleotide polymorphisms (SNPs) in FKBP5 in relation to ADHD and diurnal cortisol levels...

Progression of bipolar disorder (BD) has been associated with cognitive impairment and changes in neuroplasticity, including a decrease in serum brain-derived neurotrophic factor (BDNF). However, no study could examine BDNF levels directly in different brain regions after repeated mood episodes to date. The proposed animal model was designed to mimic several manic episodes and evaluate whether the performance in memory tasks and BDNF levels in hippocampus, prefrontal cortex, and amygdala would change after repeated amphetamine (AMPH) exposure...
