Files that contain the .ccd file extension are most commonly used by the CloneCD software application. CloneCD is a CD backup software utility that was developed by SlySoft Inc to copy CDs that contain audio files or data. CCD files contain data about the logical structure of a CD that a user is copying.
The prefrontal cortex is reliably implicated in ADHD, but we now recognize that other regions are implicated in ADHD and that it is most likely the interaction, or âcommunicationâ between brain regions that is most problematic.
Certain parts of the brain may be less active or smaller in children with ADHD than those without the disorder. The brain chemical dopamine may also play a role. It carries signals between nerves in the brain and is linked to movement, sleep, mood, attention, and learning.
