Neurotransmitters are chemicals in our brains that help send messages between nerve cells. When these neurotransmitters don’t work properly, it can lead to different mental health issues. Here are some common disorders and how they relate to neurotransmitter problems:

1. Depression:

   • Important neurotransmitters: Serotonin, Norepinephrine, Dopamine
   • About 264 million people around the world experience depression. Low levels of serotonin are involved in about 75% of these cases.

2. Anxiety Disorders:

   • Important neurotransmitters: GABA and Serotonin
   • Around 284 million people deal with anxiety globally. Low GABA levels are often linked to higher anxiety, affecting nearly 15% of people at some point in their lives.

3. Schizophrenia:

   • Important neurotransmitters: Dopamine, Glutamate
   • This disorder affects about 1 in 100 people. Changes in dopamine levels are a key factor in around 80% of cases.

4. Bipolar Disorder:

   • Important neurotransmitters: Dopamine, Norepinephrine, Serotonin
   • Approximately 46 million people worldwide have bipolar disorder. Research shows that problems with these neurotransmitters can disrupt mood.
