The main cause of anxiety and obsessive-compulsive disorder (OCD) is neurotransmitter problems in the brain, and it is more common that the balance of neurotransmitters is disturbed, and the secretion of norepinephrine, dopamine, and 5-hydroxytryptophan is abnormal. For example, the function of 5-hydroxytryptophan may be relatively hyper, which may lead to emotional problems such as over-anxiety and nervousness, and OCD is also likely to occur. If the secretion of norepinephrine is increased, it is also easy for people to experience anxiety, nervousness, easy to worry about the symptoms, manifestations, and even a variety of physical symptoms, such as panic, hand tremors, sweating, blushing and so on. So if there is a problem of anxiety OCD, the treatment is also achieved by balancing the above mentioned neurotransmitters.
