What are the causes of long-term depression??
Let’s learn a little bit about the structure of the brain.
Our brain is divided into three parts-
- Posterior brain / small brain (Hindbrain)
The anterior brain is further divided into three parts-
Just below the cerebrum, on both sides of the thalamus, there is a complex structure prsent is called the limbic system. The hypothalamus, hippocampus, amygdala and a small part of the surrounding area are included in the limbic system of brain.
We cannot even begin to imagine how important this limbic system is!He handles important responsibilities such as hunger,satisfaction, fear, emotional reactions,memory, etc.
Depression is closely releted to human brain
Let’s study with a little about neuron,Neuron is the carrier of feelings.A neuron consists of two parts
1. Cell body
2. Protruding part:
A)Dendrites- The dendrites are the parts that protrude like deer antlers from around the cell body.
B)Axon- And the long thread-like part from the bottom is called axon.
What is Depression?
Depression is a disorder of the mind that affects our thoughts, feelings or behavior. Quite a random mental state that lasts for a very short time in some cases and can last for years in others. It’s not a matter of two days, but it’s dangerous to stay after a year.Long-term depression affects not only daily activities, but also physical condition.
How do I know if someone is suffering from chronic depression?
Five or more of the following symptoms should appear at least once a day for two weeks-
- Too much or too little sleep
- Loss of interest in things that once seemed very good
- Weight gain or loss
- Appetite quite increased or decreased
- Attempted suicide
- Thinking of death or suicide more than once
- Persistent hopelessness or sadness
- Lack of attention enough to get into trouble for making decisions or thinking about something
- Mental exhaustion
- To think of oneself as unnecessarily worthless, to feel guilty
causes of long-term depression
But it is not yet possible for researchers to know exactly what causes people to fall into long-term depression. But they can guess some things.
A difficult event in life
Losing a loved one, sexual harassment, family disturbances, sudden job loss and unemployment can all lead to depression.
Depression can also be caused by hormonal imbalances in the body. This is because of the low and high levels of thyroid hormones.
Introduction to Organic Chemicals
Abnormalities in a number of chemicals inside the brain can also cause problems.
Protein is needed for all the biochemical functions of the body. And the code for making this protein comes from genes. Even our emotional responses need proteins whose source is genes. Problems will also occur if there is a fault in this gene or if we have inherited the faulty gene.
Even if there is a complex disease in the body, it has to go into depression.
How does depression affect the brain?
The outer part of our brain is gray which is known as gray matter. The reason for its gray color is the abundance of neuronal cells, dendrites and axon terminals. In people with depression, the gray matter layer is found to be thicker.
The hippocampus stores memory and regulates the secretion of a hormone called cortisol. Cortisol plays an active role in balancing blood sugar, controlling blood pressure, aiding in memory formation, controlling biological activity or reducing inflammation in any part of the body. It is also known as stress hormone. So when we go into depression the secretion of this cortisol increases. This causes the frontal lobe of the brain and the hippocampus to contract.
Anger, contentment, fear, sadness – these are all associated with amygdala. It becomes much more active during depression and its activity is quite abnormal. So when depression is chronic it has a very bad effect which also affects our emotional issues.
The thalamus and hypothalamus are also affected. The thalamus acts as a relay station, its primary responsibility for transmitting information to the cerebrum. On the other hand, maintaining the balance of the body, secretion of many important hormones, the hypothalamus works in combination with different organs. They also have abnormalities during depression.
Depression has the greatest effect on the limbic system, which is responsible for taking care of our mental state. If the person whose responsibility it is to handle the work behaves abnormally, then I can anticipate the danger.
Depression affects the brain or the brain’s reversible behavior leads to depression – a very complex issue that researchers do not seem to have finished yet.
But I must have realized the terrible changes that take place in the brain during depression. As a result of the loss of physical balance as well as radical changes in work or mental state, life becomes unbearable.
So if you get in trouble, you must take help from someone who can help you without being overwhelmed
