Addition is one of
the severe problems seen in the developed countries like United States. How
does addition take hold in the brain? In fact, what changes does it do in the
brain chemicals is associated with the addiction. The rewarding effects of
drugs of abuse come from large and rapid upsurges in dopamine, a neurochemical
critical to stimulating feelings of pleasure and to motivating behavior. The
rapid dopamine “rush” from drugs of abuse mimics but greatly exceeds in
intensity and duration the feelings that occur in response to such pleasurable
stimuli as the sight or smell of food, for example. Repeated exposure to large,
drug-induced dopamine surges has the insidious consequence of ultimately
blunting the response of the dopamine system to everyday stimuli. Thus the drug
disturbs a person’s normal hierarchy of needs and desires and substitutes new
priorities concerned with procuring and using the drug.
Drug abuse also
disrupts the brain circuits involved in memory and control over behavior.
Memories of the drug experience can trigger craving as can exposure to people,
places, or things associated with former drug use. Stress is also a powerful
trigger for craving. Control over behavior is compromised because the affected
frontal brain regions are what a person needs to exert inhibitory control over
desires and emotions.
That is why addiction
is a brain disease. As a person’s reward circuitry becomes increasingly dulled
and desensitized by drugs, nothing else can compete with them—food, family, and
friends lose their relative value, while the ability to curb the need to seek
and use drugs evaporates. Ironically and cruelly, eventually even the drug
loses its ability to reward, but the compromised brain leads addicted people to
pursue it, anyway; the memory of the drug has become more powerful than the
drug itself.
The underlying reason
of any addiction can be severe stress, depression etc. In case if addiction or
while quitting addiction, healthy brain vitamins can help to reduce stress or depression by increasing levels of
certain neurotransmitters. Thus, brain supplements can work better for
addiction or getting rid from addiction.
