A common sign of attention deficit hyperactivity disorder (ADHD) is forgetting things.
People with ADHD often forget things because their brains work differently, which changes how they think and act.
Some common examples of ADHD forgetfulness are forgetting to do daily tasks, missing deadlines and appointments, and losing important things like keys, phones, and wallets.
It’s normal to forget small things sometimes, like why you opened the fridge. But forgetfulness that gets in the way of your daily life, like missing deadlines, losing important things, or forgetting what you need to do, could be a sign of attention deficit hyperactivity disorder (ADHD).
Brain chemistry and function are different in people with ADHD, which makes it challenging for them to remember things. The good news? With the right plans and help, such as tailored organizational strategies and cognitive behavioral therapy, these problems can be solved.
