People with ADHD have a higher risk of developing other psychological or neurological disorders. Some of the more common comorbid disorders include:
Anxiety disorders: Many people with ADHD also experience anxiety. This can manifest as general worry, social anxiety, or panic attacks.
Depression: Low self-esteem and feelings of "not getting things done" can lead to depressive symptoms, especially in adults with untreated ADHD.
Learning disabilities: ADHD can often be detected alongside specific learning disabilities such as dyslexia or dyscalculia, which affect reading, writing or math skills.
Oppositional defiant disorder (ODD): This is common among children with ADHD, and is characterized by a pattern of defiant, hostile or aggressive behavior towards authority figures.
Bipolar disorder: Although the two conditions have some similarities, such as impulsive behavior, they are separate diagnoses. Many people with ADHD may have an overlapping diagnosis with bipolar disorder, which can make treatment more complex.
Sleep disorders: ADHD can lead to sleep difficulties, including difficulty falling asleep, frequent night wakings, and generally poor sleep quality.
