Brain Scan & Addiction
Review your project details
The goal is to find brain scans of different types of addictions, as well as how addictions to substances like alcohol, meth, and opiates can affect the brain.
Studies have shown that repeated opiate exposure can cause
in the brain, which negatively affects transmission, learning, and memory.
Opiates and heroin floods the brain with much more dopamine than usual and eventually
build up a tolerance
that causes the brain to naturally reduce the amount of dopamine it produces itself in the future.
from Amen Clinics, while not actual brain scans, depict what a SPECT brain scan would look like in different conditions such as healthy, after 3 years of meth use, 10 years of alcohol use, and more.
Brain scans can actually show
what kind of addict
a person is, such as a temporal lobe addict or an impulsive addict.
This article contains a
that shows the difference in natural dopamine levels in an addict at the beginning of treatment and after 14 months of recovery.
Long-term alcohol abuse can cause
, which causes amnesia, visual disturbances, and confusion.
One study showed that the damaging effects of long-term alcohol use
even six weeks after the user has stopped drinking completely.
This study showed that long term, heavy marijuana use can
affect the communication
between different areas in the brain and ultimately affect things like learning and retention.
Long-term meth use can
damage blood vessels
in the brain, causing a brain bleed. It can also cause
and impair motor skills over time.
