ADD/ADHD CHILDREN:

Children with ADD start their lives as normal children and their parents are often unaware of problems with them in the first months of their lives. They may be excessively active, or poor sleepers, but these are not unusual forms of behaviour. Problems commonly are noticed around pre-school age. They seem typically to be very serious during primary school years.

At the time of puberty the problems tend to become worse in the case of boys but often diminish in the case of girls. However, by and large, and to varying degrees, they are lifelong; it is also, regrettably, often true that by puberty so much educational and emotional damage has been done that a child has by then acquired life skills and self esteem deficiencies which will be enduring and very difficult to reverse.

The links above give two useful tests to help you determine if ADD/ADHD may be the cause of problems you are experiencing with members of your family.
