Artificial intelligence boosts MRI detection of ADHD

Deep learning, a type of artificial intelligence, can boost the power of MRI in predicting attention deficit hyperactivity disorder (ADHD), according to a study published in Radiology: Artificial Intelligence. Researchers ...

Study shows vision is not always the cause of learning disorders

Learning difficulties in schoolchildren are not always associated with visual problems, since they may be neurobiological or derived from other alterations such as dyslexia or attention deficit hyperactivity disorder (ADHD). ...

Calculating genetic links between diseases, without the genetic data

Physicians use standard disease classifications based on symptoms or location in the body to help make diagnoses. These classifications, called nosologies, can help doctors understand which diseases are closely related, and ...

Harnessing the power of machine learning for earlier autism diagnosis

When Grayson Kollins was two and a half years old—just shortly after the birth of his younger sister—his parents noticed that he had all but stopped uttering the sentences and phrases that up until then he had been using ...

Three types of cells help the brain tell day from night

Bright light at night interrupts the body's normal day-night cycles, called circadian rhythms, and can trigger insomnia. In fact, circadian rhythms play a major role in health. Disrupted day-night cycles have even been linked ...

Genetics

Autism and ADHD share genes

Researchers from the national psychiatric project iPSYCH have found that autism and ADHD share changes in the same genes. The new knowledge relates directly to the biological causes of the two child psychiatric disorders.

Non-opioid drug death rates are also on the rise

Drugs overdoses in the United States have been on the rise, and studies have paid particular attention to prescription opioids, heroin and synthetic opioids, such as fentanyl. But University of Virginia researcher Christopher ...

Attention deficit hyperactivity disorder (ADHD) is a developmental disorder. It is characterized primarily by "the co-existence of attentional problems and hyperactivity, with each behavior occurring infrequently alone" and symptoms starting before seven years of age.

ADHD is the most commonly studied and diagnosed psychiatric disorder in children, affecting about 3 to 5 percent of children globally and diagnosed in about 2 to 16 percent of school aged children. It is a chronic disorder with 30 to 50 percent of those individuals diagnosed in childhood continuing to have symptoms into adulthood. Adolescents and adults with ADHD tend to develop coping mechanisms to compensate for some or all of their impairments. It is estimated that 4.7 percent of American adults live with ADHD. Standardized rating scales such as the World Health Organization's Adult ADHD Self-Report Scale can be used for ADHD screening and assessment of the disorder's symptoms' severity.

ADHD is diagnosed two to four times more frequently in boys than in girls, though studies suggest this discrepancy may be partially due to subjective bias of referring teachers. ADHD management usually involves some combination of medications, behavior modifications, lifestyle changes, and counseling. Its symptoms can be difficult to differentiate from other disorders, increasing the likelihood that the diagnosis of ADHD will be missed. In addition, most clinicians have not received formal training in the assessment and treatment of ADHD, in particular in adult patients.

ADHD and its diagnosis and treatment have been considered controversial since the 1970s. The controversies have involved clinicians, teachers, policymakers, parents and the media. Topics include ADHD's causes, and the use of stimulant medications in its treatment. Most healthcare providers accept that ADHD is a genuine disorder with debate in the scientific community centering mainly around how it is diagnosed and treated. The American Medical Association concluded in 1998 that the diagnostic criteria for ADHD are based on extensive research and, if applied appropriately, lead to the diagnosis with high reliability.
