Inability to concentrate

A typical sign of anxiety is an inability to focus on daily tasks (although it can also be associated with other disorders, like ADHD). Many people with anxiety disorders say that this is one of the symptoms that has the most influence on their lives since it makes it difficult or impossible to function well at work or enjoy hobbies and pastimes.

It's unlikely that your inability to concentrate is due to an anxiety problem if you don't have any concomitant emotions of worry or anxiousness. However, it's still worth seeing a doctor or therapist about it, as it might be a symptom of something worse. Many people with anxiety experience absentmindedness or forgetfulness as a result of their difficulty concentrating, which can be a source of anxiety and reinforce bad sentiments.
