Attention deficit hyperactivity disorder - ADHD

Adult Attention Deficit Hyperactivity Disorder (ADHD)

ADHD is a complex mental health disorder and symptoms can differ from person-to-person. It is usually diagnosed in early childhood but can also affect adults later in life.

Adult ADHD

ADHD is usually recognised during childhood however this is not always the case. Sometimes people may only become aware of a problem in adulthood, possibly when their child is diagnosed, or relatives or friends recognise symptoms and bring it to their attention.

Adult ADHD describes the behaviours displayed by some adults who are extremely restless, energetic, impatient and easily distracted.

Short attention spans make it diffi­cult for those with ADHD to concentrate properly on work or life at home. Adults with the disorder will find it di­fficult to manage time and struggle sleeping, which can have a negative impact on everyday life.

3% of adults are affected by the mental health condition ADHD

While the exact cause of ADHD is unknown, research has suggested that people with the disorder have differences in parts of their brain which deal with impulse and focus. There is also strong evidence to suggest there may be a genetic element or that symptoms can be due to a poor diet.
