Final answer:
Depressed mood states are linked to low levels of serotonin and low levels of norepinephrine.
Step-by-step explanation:
Depressed mood states are linked to low levels of serotonin and low levels of norepinephrine.
Depression is a mental disorder that affects many people. It is believed that imbalances in neurotransmitters like serotonin and norepinephrine are one of the causes of depression. Serotonin is known to play a role in mood control, and low levels of serotonin are associated with depressed mood states. Similarly, low levels of norepinephrine have also been linked to depression.
There are medications called antidepressants that can help regulate the levels of these neurotransmitters in the brain, reducing the symptoms of depression and improving the overall well-being of individuals.
