ADHD is developmental disorder, like ASD. Whilst it can be comorbid with learning disorders such as dyslexia, and dyscalculia, etc, it is not a learning disorder itself. It's also not a behavioural disorder.
ADHD is classified in 3 presentations in both the DSM (4 & 5), and the ICD-10-CM and ICD-11.
Predominantly Inattentive (formerly known as ADD)
Predominantly Hyperactive-Impulsive
Predominantly Combined (Meaning you exhibit 5 or more symptoms from both PI and PH)
