Depression
A chronic, recurring, and life threatening condition characterized by constant emotions of sadness, loss of interest in activity, irritability, weight changes, and social isolation.
What is Depression?
The structures of the limbic system: amygdala, hippocampus, and thalamus.
What are the three structures of the limbic system of the nervous system that are related to depression?
low levels of monoamines result in symptoms of depression by decreasing the efficiency of neuron signaling.
What is the monoamine hypothesis?
How many adolescents had at least one major depressive episode?
What is 2.8 million/ 11.4%
True or False: Suffering from depression can make a teen 10 times more likely to commit suicide
False, 12 times more likely…What is a Surprising Fact?
A neurotransmitter that produces a feeling of excitement and power. Its low levels can result in low self-esteem and defeat, fueling depressive episodes by activating receptors in the nerve cell membrane.
What is Norepinephrine?
The amygdala is the main perception center of extreme emotions such as fear, sadness, and anger. When an individual is going through depression, their amygdala will be overactive and they will respond more excessively with emotions such as fear, sadness, and anger.
How does the amygdala respond to depression?
Drugs that work by mimicking the chemical structure of serotonin and binding to the serotonin reuptake channel.
What is SSRIs?
[CED 3.1, 3.3(ENE - 7G.4) - Learning Objective 2 + Additional Research]
Three remedies that aid in overcoming depression?
What is medication, psychotherapy counseling and healthy habits (diet and exercise)

The neurotransmitter binds to the receptor which is attached to the nerve cell membrane and sends a signal.
What is the Reception stage of the Neuron Signal Transduction Pathway?
The host neuron takes in all of the excess neurotransmitters that did not bind to the receptors of the dendrites of the adjacent neuron.
What is “reuptake,” the process that may happen after the signal transduction pathway?
This process consists of these enzymes using oxygen to remove an amine group, and an adjacent hydrogen atom from a target molecule.
What is oxidative deamination by monoamine oxidases?
CED 3.3)
What are some ways to cope with emotions?
What is behavioral/family/group therapy, medication, creative outlet
It covers how depression is a mental illness common in teens which is affected by a series of physical, chemical, and physiological signals and can be treated by several antidepressants, including SSRIs for teens, or therapy. It emphasizes how low levels of neurotransmitters and neurological/biological changes characterize depression and highlights how, while there are several emotional and physical side effects to antidepressants, medication can greatly improve the condition in teens.
What is the summary and importance of this article?
The neurotransmitter binds to the receptor which is attached to the nerve cell membrane and initiates a signal.
What is the Reception stage of the Neuron Signal Transduction Pathway?
Brain structures have neurons, signaling cells, within the nervous system and they operate by sending signals to one another by releasing chemical messengers called neurotransmitters.
How do the structures of the brain receive signals in order to pass on information?
A farther-reaching biochemical consequence of antidepressants.
What is antidepressants may encourage the growth of new neurons?
(CED 4.5)
True or False: Depression is highly treatable
True, it is estimated that 80 percent of depression cases are managed
Neurotransmitters act as ligands in juxtacrine signaling as well as function to initiate transduction events inside the thalamus which affect mood.
What is Signal Transduction Pathways/Transduction Stage/Cascades (Learning Objective 1 from the CED: 4.3 Signal Transduction)
Neurons inside the amygdala, thalamus, and hippocampus region send signals through the nerve cell membrane in the synaptic terminal which can affect a person’s mood and behavior. These signals, in combination with other physical and chemical responses, can lead to depression.
What is how Signal Transduction Pathway of neurons causes depression?
The neurotransmitters travel across the synapse and bind to the receptors of the receiving neuron’s dendrites. These dendrites pass on the signal to the cell body, through the axons, and finally to the axon terminal, where it is released in the form of a neurotransmitter, which can bind to the dendrites of another neuron.
How does a signal travel through the structures of a neuron?
Causes depression to get a lot worse, and should not happen without consulting a doctor.
What is quitting SSRIs?
Urging others to seek help when necessary, participating in this jeopardy to understand the chemical and biological symptoms of depression and staying away from alcohol.
What is helping others who have depression as a teenager
Name one supplementation option that has proven successful in depression treatment, as well as a treatment plan that has been proven inefficient.
(many options) Some include: (What is) Folic Acid supplementation, SAM-e supplementation, Omega 3 fatty acid supplementation; (What is) Acupunture? (Merits/Pauses + Additional Research)
