The Basic Effects and functions of Dopamine to the Brain Cells

Updated on August 5, 2016

Dopamine is a neurotransmitter which ensures that our nerves can communicate with each other. This hormone has great influence on our feelings. An appropriate amount of dopamine in our brains gives us a positive and active sense and allows us to feel happy. But sometimes the recording could be disturbed and in such condition medications should be taken. This occurs in patients with Parkinson's disease. But people who are depressed or suffer from anorexia nervosa may have impaired dopamine uptake.

What is dopamine?

Dopamine is a neurotransmitter which enables our nerves to communicate with each other. It is produced by the amino acid L-tyrosine used by the body. In condition like Parkinson's disease, people have a deficiency of dopamine in the brains. The brain stem is located in the deeper parts of our brain called the black core. It is the area in which automatic movements are being controlled, and this is of great importance.

The body movements are taken very serious but in people whose dopamine uptake is disturbed this can cause uncontrolled movements. Again serotonin is the second counterpart of Dopamine. Dopamine is released in punches in the brains while serotonin exhibits a regular uptake in the brains. Dopamine stimulates the reward system in our brains, especially when its amount is low, resulting to high fatigue. Then, if one is already tired, it takes even more effort to take action because there is no compensation in return. Also, dopamine has a great influence on our sex life.

Anorexia nervosa:

Individuals with anorexia nervosa sometimes may have impaired absorption of the dose of dopamine. This is further caused by low body weight called hyperactivity. This has to do with the amount of dopamine that is not properly regulated in these patients.

Dopamine and addiction:

Dopamine may also play a role in addiction. If you drink a glass of alcohol you get a surge of dopamine. This raises a good feeling which may trigger you to do more. But too much of this could be an addiction. This usually occurs in gambling phenomenon.

Dopamine and the brains: Dopamine is an endogenous substance that is released automatically in healthy people usually in the brains. However, Dopamine controls the following activities in the brain :

  • Our motivation and our emotions
  • Learning Achievements
  • Sex drive
  • Control over your movements

Foods containing dopamine:

Sometimes it's good to pay attention to the diet and to choose that which contains tyrosine. In order to produce dopamine in the brains, the body needs L-tyrosine. We can find this in the following below:

  • Almonds
  • Avocado
  • Banana
  • Chocolate
  • Dairy produce
  • Pumpkin seeds
  • Many fruits and vegetables
  • Red meat

Eating protein-rich foods and fewer carbs is essential and should be observed.


Several exercises and cycling are good to tri dopamine. But swimming and other sports raise dopamine levels. It is important to make the move to longer time in successive effort, including cycling for half an hour per day. Even walking is a good way of moving.


In some cases it is necessary to take drugs issued with carbidopa and levodopa. This is good in cases where there is Parkinson’s disease disorder. These patients have a delay in absorption of dopamine in the brains and the drug levodopa allows for regulation and replenishment. After a short time you will find that moving some smoother and stiffness caused by this disease will diminish.This medication should not be stopped suddenly, discontinuation should always be done in consultation with the doctor. At the start, there will be dizziness or nausea occurrence as a side effect but generally, this will disappear quickly. Driving is permitted as long as you feel fit. Also levodopa is prescribed for metabolic disease as a means to reduce the symptoms.


In order to determine how the dopamine in the brains is transported, there may be a DAT-scan to be made. This can be determined, if there is sufficient dopamine in the brains. During the scan, a little radioactive substance is injected with ioflupane and this works for 3 hours. Thereafter, a scan is made of the head. To limit the effects of the radioactive liquid before treatment, iodine isotopes are provided. The DAT-scan are used not only in patients whom are diagnosed of Parkinson's disease but also in patients that have be diagnosed with dementia such as Alzheimer's disease.
