Research has found that addiction is a medical disease associated with biochemical changes in
the brain. These changes in brain chemistry play a significant role in the physical symptoms of
addiction, including cravings and withdrawal. To better understand addiction, it is important
to be familiar with the general findings of clinical research:

All addictions are characterized by dysregulation of specific
neurochemical mechanisms in reward and/or stress circuits.

Neurochemical changes can lead to long-term adverse changes in
cognition, decision-making and reasoning, which can affect recovery.

Addressing the physiological aspects of addiction may enhance the
effectiveness of psychosocial treatment for those on the road to recovery.
