   ADHD stands for attention deficit hyperactivity disorder. It is a common disorder that often results in learning difficulties. People with this disorder act impulsively and are easily distracted. They may also exhibit hyperactive behavior. While some specialists consider ADHD a behavioral disorder, others call it a cognitive disorder.

   The cause of ADHD is unknown. However, brain scans indicate that it may be caused by abnormal size, function, and form of the brain’s frontal lobe. There may also be an imbalance of chemicals in the brain. ADHD is believed to be inherited in most cases, but it is also prevalent in premature babies and children who have experienced head injuries.  

   The disorder ADD (attention deficit disorder) was renamed ADHD to account for the “hyperactivity” that is often one of the major symptoms found in people with the disorder. The disability can exist without the presence of hyperactivity, in which case it is referred to as a subset of ADHD called ADD. Both terms are often used to describe the same disorder.

    Children can exhibit ADHD symptoms at a very young age, and are often diagnosed before the age of seven. On the other hand, some adults do not realize they have this disorder until their own children are diagnosed with it. Some symptoms, such as hyperactivity, may be less severe as a child ages and learns coping mechanisms.

      Synthetic media technologies are rapidly advancing, making it easier to generate nonveridical media that look and sound increasingly realistic. So-called “deepfakes” often present a person saying or doing something they have not said or done. The proliferation of deepfakes has already created negative consequences such as nonconsensual pornography, political disinformation, and financial fraud. Deepfakes can harm viewers by deceiving or intimidating, harm subjects by causing reputational damage, and harm society by undermining societal values such as trust in institutions.

      It will take the efforts of many different stakeholders including platforms, journalists, and policymakers to counteract the negative effects of deepfakes. Technical experts must marshal their expertise and direct their efforts to find solutions that allow the beneficial uses of synthetic media technologies and mitigate the negative effects. 

      There is no doubt that synthetic media can be used for beneficial purposes, such as in entertainment, historical reenactment, education, and training. The pressing challenge is to reap the positive uses of synthetic media while preventing or at least minimizing the harms. There are numerous opportunities to direct effort in buttressing against some of the worst outcomes.
