Serotonin: a compound found in blood platelets that constricts the blood vessels and acts as a neurotransmitter. 
Dopamine: a compound present in the body as a neurotransmitter and is responsible for sending messages between the brain and different nerve cells in the body.  ]]> 2018-05-22 01:07:51 UTC https://padlet.com/175581/xb9er8u27nkv/wish/262538814 175581 https://padlet.com/175581/xb9er8u27nkv/wish/262540182 Nor-adrenaline and serotonin are also linked to mood disorders.]]> 2018-05-22 01:17:54 UTC https://padlet.com/175581/xb9er8u27nkv/wish/262540182 175581 https://padlet.com/175581/xb9er8u27nkv/wish/262540374 Dopamine controls nerve pathways in the brain that are linked with pleasure and emotional rewards.]]> 2018-05-22 01:19:20 UTC https://padlet.com/175581/xb9er8u27nkv/wish/262540374 175581 https://padlet.com/175581/xb9er8u27nkv/wish/262540463 Serotonin is also connected to many body functions, like sleep, learning, impulsiveness, and memory. ]]> 2018-05-22 01:20:00 UTC https://padlet.com/175581/xb9er8u27nkv/wish/262540463 175581 https://padlet.com/175581/xb9er8u27nkv/wish/262540572 Abnormal functioning of serotonin brain cells can result in mood disorders. ]]> 2018-05-22 01:20:52 UTC https://padlet.com/175581/xb9er8u27nkv/wish/262540572 175581 https://padlet.com/175581/xb9er8u27nkv/wish/262541057 Researchers use machines like the fMRI (functional magnetic resonance imaging) and the PET (positron emission topography) to take pictures of someone's brain with bipolar disorder.]]> 2018-05-22 01:24:17 UTC https://padlet.com/175581/xb9er8u27nkv/wish/262541057 175581 https://padlet.com/175581/xb9er8u27nkv/wish/262541682 fMRI: Measures brain activity by monitoring changes associated with blood flow.

The neuron that receives the message then alerts other neurons that it has a message, and the process continues.
Along with the neurotransmitters mentioned earlier, GABA, glutamate, acetylcholine is believed to be connected with bipolar disorder.

People with bipolar disorder tend to have higher oxytocin levels than someone that didn’t have a mood disorder.

Someone with bipolar disorder might fluctuate between low and high levels of thyroid hormones which can create a fall or elevation of mood. ]]> 2018-05-23 21:26:11 UTC https://padlet.com/175581/xb9er8u27nkv/wish/263173648 175581 https://padlet.com/175581/xb9er8u27nkv/wish/263174086 Even though not a lot is known about this, another component in the endocrine system that can affect mood when not regulated is the reproductive system when the ovaries produce estrogen and testosterone. Several studies have identified abnormal changes in the immune system that can vary based on the severity of someone with bipolar disorder. ]]> 2018-05-23 21:28:38 UTC https://padlet.com/175581/xb9er8u27nkv/wish/263174086 What does bipolar disorder look like in the brain? 175581 https://padlet.com/175581/xb9er8u27nkv/wish/263175512 Published by researchers from the University of Southern California Keck School of Medicine through a study where the brain of someone with bipolar disorder was monitored. The brain regions that are damaged the most are for inhibition and emotion.

I have some people in my life with bipolar disorder, it's a concept that I have always wanted to understand more. Personally I struggle sometimes with maintaining my mood and although I don't have bipolar disorder, it's vital for me to understand how it works so that I can help people who are struggling with the disorder. My secret hope is that people who struggle with bipolar disorder can find peace and serenity with themselves and hold no judgement regarding who they are.
