Low dopamine levels are linked to ADHD, a condition characterized by difficulty concentrating, hyperactivity, and impulsivity. Environmental factors and genetics can contribute to the development of ADHD, which can lead to an increased risk of drug and alcohol use. Stimulant drugs and antidepressants can help level dopamine levels and reduce symptoms.
Dopamine is a type of neurotransmitter or brain chemical. It helps level the nervous system, thereby reducing anxiety and stress, and is responsible for feelings of motivation. When a person has optimal dopamine levels, that person has control over their feelings and mood. Researchers have found a connection between low dopamine levels and attention deficit hyperactivity disorder (ADHD). Decreased dopamine in the brain is thought to be one cause of ADHD.
ADHD is a health condition that begins in childhood and can progress into adulthood if left untreated. The condition, which has become increasingly common, is characterized by difficulty concentrating, hyperactive behavior, lack of organizational skills, low self-esteem and impulse acting. Children who have ADHD often have problems in school academically and socially.
There are several theories on how a child develops ADHD. Certain environmental factors, such as toxins, can affect a child’s brain development. Most commonly, ADHD is believed to be hereditary. A lack of dopamine in the brain develops before birth or during early childhood. Environmental elements could further influence dopamine and ADHD, but they are not thought to be the only cause.
Dopamine and ADHD are linked to an increased risk of drug and alcohol use. Prolonged exposure to dopamine can cause mood swings and depression. One of the reasons many people start abusing drugs and alcohol is to help level their mood. The drugs also tend to increase dopamine levels, which is why some ADHD patients are at risk of overusing them. The fact that ADHD causes impulsive behavior only increases the risk of trying alcohol and drugs, particularly at a young age.
Some medications are used to treat dopamine and ADHD. Doctors usually prescribe stimulant drugs, such as amphetamines and methylphenidate. These stimulants also increase the amount of neurotransmitters, including dopamine. Symptoms of hyperactivity reduce while patients take the drug. However, after a patient stops using this medication, ADHD symptoms are likely to return.
Antidepressants might also help level dopamine levels, thereby reducing symptoms of anxiety and stress. These drugs are sometimes used in place of stimulants and are more common in older children and adults. Doctors generally look at antidepressants as an alternative when a patient is unresponsive to stimulants.
Researchers have continued to examine the effects of low dopamine and ADHD. The brain is a complex organ, with different chemicals. A dopamine imbalance is only one cause of ADHD.
