Frequent phone usage has caused a rise in ADHD in adults.
Doctors have been attempting to figure out what has caused the steady increase in Attention deficit hyperactivity disorder (ADHD) and a new study suggested that those who use their smartphones for two or more hours every day are 10 per cent more likely to develop the condition.
ADHD is mainly linked to young children but researchers argue that smartphones provide people with frequent information, meaning that they take breaks from tasks to check their devices.
People who spend too much time on their phones don't let their brains focus on just a single task and it can cause adults to develop shorter attention spans and get distracted easily.
John Ratey, an associate clinical professor of psychiatry at Harvard Medical School, told National Geographic: "It is legitimate to look at the possibility of acquired attention deficit."
