Because of that, high-levels of dopamine can feel extremely good. But it can also lead to abuse of drugs, which can have severe consequences.
Motivation seems like a prerequisite to learning and attention - and it is, in a way. We already know that brain dopamine has been linked to motivational functions. 
Dopamine is crucial for the "production" of stimulus-reward response.
And this response is needed for the motivation in a previous-reward situation. If dopamine function is blocked, however, the motivation will weaken.
Motivation is the process that activates behavior. 
So, dopamine deficiency can cause a myriad of issues including low motivation levels, which can result in poor cognitive function.
Last but not least, let's talk about the impact of dopamine on our mood. If we said before that motivation is the prerequisite for learning, then we could say that a good mood is a prerequisite for motivation.
It is logical, right? How could you be motivated if you are in a state of depression, anxiety, or simply not in a good mood?
Studies have shown that mood has a pervasive effect on cognition.  It is rather important to boost your mood in order to improve your cognitive function. Luckily, we also know that dopamine is the brain chemical that can help you out.
Adequate dopamine production is needed to stabilize the nervous system, ensure normal brain health, decrease stress and anxiety, and can have a long-term impact on your mood.
So far we talked about the importance of normal dopamine levels and its effects on our cognitive function. Now let's look at what happens if we have low dopamine levels.
