Changes in the brain make people prone to alcoholism

The brain tissue of persons with alcohol dependence shows a variety of changes compared to non-alcoholic control persons. All alcoholics' brains share some characteristics, but some are exclusive to the brain tissue of anxiety-prone type 1 alcoholics or impulsive type 2 alcoholics, according to a recent study from the University of Eastern Finland.

Study shows how Down Syndrome gene associated with altered oscillations in the cerebral cortex

Cerebral activity is governed by a fine balance between neuronal excitation and inhibition. Specifically, neurons are activated by excitation mechanisms tightly regulated by inhibition processes. For certain functions, the neuronal network needs to be synchronized.

ADHD increases risk of becoming obese

With the incidence of obesity increasing steadily, much research has been undertaken to try and identify those people who are most likely to become obese so measures can be taken to avoid excessive weight gain, since it is easier to prevent than to reverse.

Study shows gambling among young teens associated with risk-taking behavior

Gambling among young teens may be associated with increased use of alcohol, cigarettes, or marijuana according to a study that surveyed sixth- to eighth-graders in Italian schools. The research is reported in the February issue of the Journal of Developmental & Behavioral Pediatrics, the official journal of the Society for Developmental and Behavioral Pediatrics.

Stimulant medications for ADHD cause sleep problems among children

Stimulant medications for attention-deficit/hyperactivity disorder (ADHD) cause sleep problems among the children who take them, a new study from the University of Nebraska-Lincoln concludes.

Preference-based decisions become less stable when information flowing between brain regions gets disrupted

Some people find it difficult to make decisions. In a new study, neuroeconomists from the University of Zurich now reveal that the intensity of the communication between different regions of the brain dictates whether we are indecisive or not.

UC Berkeley research explores link between ADHD and childhood maltreatment

Young women with ADHD who have been exposed to abuse, neglect or other traumas in childhood and adolescence are at greater risk for self-injury, eating disorders and suicide than those with ADHD who were not mistreated in early youth, according to new research from UC Berkeley.

Genetic risk for ADHD contributes to language, attention deficits in general population

Are deficits in attention limited to those with attention-deficit/hyperactivity disorder (ADHD) or is there a spectrum of attention function in the general population?

Stress coping strategies may protect against bipolar disorder recurrence

Researchers have found a link between low levels of resilience to stress in euthymic patients with bipolar disorder and impulsive behaviour, which may make them vulnerable to depressive episodes.

Lower rates of suicide linked with more daily sunshine

Lower rates of suicide are associated with more daily sunshine in the prior 14 to 60 days. Light interacts with brain serotonin systems and possibly influences serotonin-related behaviors. Those behaviors, such as mood and impulsiveness, can play a role in suicide.

Study of chronic users of CCS finds deficits in specific regions of brain white matter

An imaging study of chronic users of codeine-containing cough syrups (CCS) has found deficits in specific regions of brain white matter and associates these changes with increased impulsivity in CCS users.

Actor's suicide shows complexities of depression and its treatment

The Washington Post looks at how Robin Williams' death has reignited a national conversation about mental health issues and treatment, and whether public attitudes toward diagnosis and treatment are changing.

Impulse control predicts euthymia in bipolar disorder

Patients with bipolar disorder who have good trait impulse control are likely to respond better to treatment than those with poor impulse control, say researchers.

Study analyses whether connectivity of infant's brain is related to children's impulsiveness

Researchers from the University of Murcia have studied the changes in the brain that are associated with impulsiveness, a personality trait that causes difficulties in inhibiting a response in the face of a stimulus and leads to unplanned actions without considering the negative consequences.

Study confirms neurobiological origin of attention-deficit disorder

A study, carried out on mice, has just confirmed the neurobiological origin of attention-deficit disorder (ADD), a syndrome whose causes are poorly understood. Researchers from CNRS, the University of Strasbourg and INSERM1 have identified a cerebral structure, the superior colliculus, where hyperstimulation causes behavior modifications similar to those of some patients who suffer from ADD.

Heritable bipolar phenotypes pinned down

A large study has pinpointed brain and behavioural traits that are genetically influenced and associated with bipolar I disorder.

Preterm infants at high risk for significant long-term problems

Premature birth appears to trigger developmental processes in the white matter of the brain that could put children at higher risk of problems later in life, according to a study being presented next week at the annual meeting of the Radiological Society of North America (RSNA).

Impulsivity in bipolar disorder unrelated to substance abuse

Trait impulsivity is elevated and neurocognitive functioning is impaired in patients with bipolar disorder irrespective of whether they have a substance abuse history, research shows.

Impulsivity may be vulnerability marker for bipolar disorder

People with bipolar disorder type I are significantly more impulsive than the general population, while their siblings show an intermediate level of impulsivity, a study by Brazilian researchers shows.
