What happens when neurotransmitters don’t work right?

When Neurotransmitters Do Not Work Right Neurons might not manufacture enough of a particular neurotransmitter. Neurotransmitters may be reabsorbed too quickly. Too many neurotransmitters may be deactivated by enzymes. Too much of a particular neurotransmitter may be released.

What causes an imbalance in neurotransmitters?

Genetics, environment, chemicals and nutritional deficiencies are a few factors that can result in over- or under-production of neurotransmitters. Once out of balance, the nervous system begins to compensate – which, in time, can lead to neurological or psychological symptoms.
