Peripheral levels of BDNF and opiate-use disorder: literature review and update.

Several neurobiological factors are related to opiate-use disorder (OUD), and among them, neurotrophins have a relevant role. Brain-derived neurotrophic factor (BDNF) is a central neurotrophin involved in many neuronal processes, and it has been related to several psychiatric diseases and addictive disorders. BDNF can be measured in plasma and serum; its levels may reflect BDNF concentrations in the central nervous system (CNS) and, indirectly, CNS processes.

Cocaine-induced Psychosis and Brain-derived Neurothrophic Factor in Patients with Cocaine Dependence: Report of Two Cases.

Brain-derived neurotrophic factor (BDNF) is linked to numerous brain functions. In addition, BDNF alterations contribute to neurological, mental, and addictive disorders. Cocaine dependence has received much attention recently due to its prevalence and psychological effects.

Cortisol Response to Stress in Adults with Attention Deficit Hyperactivity Disorder.

Background: Differences in the cortisol response have been reported between children exhibiting the inattentive and hyperactive/impulsive subtypes of attention deficit hyperactivity disorder. However, there is no such information about adults. The aim of the present study was to determine the possible differences between the combined and inattentive subtypes in the cortisol response to stress.

Changes in brain-derived neurotrophic factor (BDNF) during abstinence could be associated with relapse in cocaine-dependent patients.

Brain-derived neurotrophic factor (BDNF) is involved in cocaine craving in humans and drug seeking in rodents. Based on this, the aim of this study was to explore the possible role of serum BDNF in cocaine relapse in abstinent addicts. Forty cocaine dependent subjects (DSM-IV criteria) were included in an inpatient 2 weeks abstinence program.

Serum brain-derived neurotrophic factor levels and cocaine-induced transient psychotic symptoms.

Background: Cocaine-induced psychosis (CIP) is among the most serious adverse effects of cocaine. Reduced serum brain-derived neurotrophic factor (BDNF) levels have been reported in schizophrenia and psychosis; however, studies assessing the involvement of BDNF in CIP are lacking.

Methods: A total of 22 cocaine-dependent patients (aged 33.

Decreased serum levels of brain-derived neurotrophic factor in adults with attention-deficit hyperactivity disorder.

It has been hypothesized that brain-derived neurotrophic factor (BDNF) is involved in the pathogenesis of attention-deficit hyperactivity disorder (ADHD), although experimental data regarding the contribution of BDNF gene polymorphisms to this psychiatric disorder are controversial. Recently, changes in BDNF serum levels have been reported in children with ADHD, but there are no studies about the possible role of this neurotrophin in adults. A total of 54 Caucasoid ADHD adults, including the predominantly inattentive and combined types (aged 33.

Brain-derived neurotrophic factor serum levels in cocaine-dependent patients during early abstinence.

Preclinical studies indicate that brain-derived neurotrophic factor (BDNF) is involved in neuroplastic changes underlying enduring cocaine-seeking following withdrawal. However, little is known about temporal changes in serum BDNF levels or the involvement of BDNF in craving and abstinence in early-abstinent cocaine-dependent patients. Twenty-three cocaine-dependent individuals (aged 33.
