How
Substance Abuse Transforms Memory
Multiple studies have shown that
substance abusers tend to score lower on mental agility test that
involve aspects like memory and fact recall. Short term memory is
the first portion of memory that is affected once a person begins
abusing substances; however, after the abuse remains continuous
long term memory and the ability to learn new things may also be
impaired. Some of the forms of substance abuse that have show to
affect memory are:
- Alcohol abuse – those who abuse alcohol
over long periods of time show the most impairment. Binge alcohol
use also shows to have negative effects on memory.
- Illegal Drugs – Marijuana, cocaine
and other drugs have all shown to have negative effects on memory
after prolonged use. Short term memory is affected even after
minimal use.
- Prescription Drugs – Abuse of prescription
pain medication over long periods of time may also cause memory
impairment.
Recently studies at Harvard have shown that
drugs may cause what they term “extreme memories” that
actually can influence addiction. While under the influence of narcotics,
large amounts of dopamine are being excreted by the brain. Because
dopamine is one of the most essentially chemicals in the human mind,
and it tends to be excreted in response to extreme pleasure, the
brain falsely remembers the drug experience as good – hence
addiction becomes that much more possible. If you are addicted to
substances you should contact your physician immediately so he or
she can help you decide what the best route of treatment will be
for you.
