Depression | Types, Symptoms, causes and Treatment

Depression is a leading cause of disability in the world. Depression is a mental illness so it is a lot harder to understand than normal diseases like cholesterol, heart diseases, etc.

But most of the people are confused between having depression and just feeling depressed. Everyone at some point in life feels depressed for losing a job, having a bad grade, even a rainy day can bring a feeling of sadness. When circumstances change and sadly gone this called feeling depressed.

But clinical depression is different, it is a medical disorder and it won’t go away just because you wanted to.

It lingers for at least two consecutive weeks and significantly interferes with one’s ability to work and play. Depression can have a lot of different symptoms

What are depression and anxiety?

Anxiety and depression are two different phenomena but they are related. If someone is very anxious for an extended period of time. It started to interfere in a lot of things to do like school performance, in a relationship, marriage, etc. these are chronic anxiety.

Most people have that high-level anxiety would also start to experience depression due to the hopeless scenario and helpless to do anything. Due to anxious for a long period of time the person started to depress.

But at some point anxiety and depression need to be treated.

Depression is not just behavioral symptoms. It has a physical structure in the brain. Changes in the brain can be seen in X-Ray vision this includes smaller frontal lobe and hippocampus volume.

More in microscale depression is associated with a few things the abnormal transmission and depletion of certain neurotransmitters.

Especially serotonin, norepinephrine, and dopamine. Neuroscientist still doesn’t have a complete picture of what causes depression.

It seems to have to do with the complex interaction between genes and environment. But we don’t have the tool to calculate the depression where and when it shows up?

The science behind depression

In past depression was often described a simple chemical imbalance in the brain. Scientists believe that a lack of the neurotransmitter serotonin was to blame which often refer to feel good chemical.

However, the only real evidence for this was that when some depressed people prescribed a drug which increases serotonin level it alleviates their symptoms.

But in recent years scientist began to notice that brain cell growth and connection may actually play a larger role.

When the doctor tries to look brain of the depressed person then study shows that the hippocampus tends to be much smaller than the average person. Other areas of the brain physically also affected.

But this reason particularly controls memory and emotion. The longer the person has been depressed the smaller the hippocampus become. The cells and connection literally deteriorate.

It tells that the stress may be the main reason for decreasing the neuron in that reason.

In study is shown that when this reason of the brain regenerated and new neurons stimulated mood improves.

This why serotonin-based drug help some people because it promotes the release of the other chemical which automatically stimulates the growth of the new neuron cells.

So some scientist believes that our focus should be on the drug which directly affects neurogenesis.

In one particular study found that variation in serotonin transporter gene leaves the individual more vulnerable to depression.

Every individual has to copy of the gene, one from each parent. And these genes can be short or long.

After collecting data from various subjects the study reveals that 33% of individuals with one short version and one long become depressed after stressful life events and people with two short genes fared even worse.

On the other hands, those with two long genes were much less likely to become depressed with similar life stress.

The true cause of the depression has to be figured out precisely yet. But you should remember that depression is a disease with a biological basis along with psychology and social implication. It is not a weakness that everyone should get over this
