No offence intended but where tf did they find people with lung cancer that aren’t depressed?

That's a good question. It is of course very natural to be sad about a diagnosis of lung cancer. That's not the same as depression. Severe depression is not normal, even if it is somewhat common -- about one-third of patients do have that. The important thing is that the depression can be treated and patients can be helped.

Me. Why be depressed because that's not going to help anything or anyone. I just stay upbeat because it helps keep my family from being all gloomy and doomy. Having a positive outlook can't hurt.

Depression isn't a little switch you turn on and off, at least not clinical depression which is what I presume the study is talking about. You may mean the colloquial-used "depression" aka situational/reactive depression that many use to mean "really sad for a while" but it's not the same.

See this article from UC Berkeley for an explainer. Here are some quotes:

> Clinical depression is a serious medical illness that negatively affects how you feel, the way you think and how you act. Individuals with clinical depression are unable to function as they used to. Often they have lost interest in activities that were once enjoyable to them, and feel sad and hopeless for extended periods of time. Clinical depression is not the same as feeling sad or depressed for a few days and then feeling better. It can affect your body, mood, thoughts, and behavior. It can change your eating habits, how you feel and think, your ability to work and study, and how you interact with people.

> Clinically depressed people cannot "pull themselves together" and get better. In fact, clinical depression often interferes with a person's ability or wish to get help. Clinical depression is a serious illness that lasts for weeks, months and sometimes years. It may even influence someone to contemplate or attempt suicide.

> Feeling sad and depressed is often a normal reaction to a stressful life situation. For example, it is normal to feel down after a major disappointment, or to have trouble sleeping or eating after a difficult relationship break-up. Usually, within a few days, perhaps after talking to a friend, we start to feel like ourselves again. Clinical depression is very different. It involves a noticeable change in functioning that persists for two weeks or longer.

"Why be depressed?" makes the same amount of sense as "Why have lung cancer?"

Weird take, but ok. In my case, and I'm talking about my case only, I didn't have a choice about getting cancer. I can, however, decide how I choose to react to that diagnosis. That was all I was trying to convey.

I seem to recall seeing something a year or two ago talking about how chronic inflammation was linked to depression. So maybe the link isn't depression leads to inflammation but rather inflammation leads to depression

We know that depression is linked to exercise, sleep and diet. The actual mechanisms aren't clear but it could be due to BDNF, increased microcondrial health, brain volume, blood flow, anti-inflammatory, etc.

So it might be that depression is just correlated to poor survival rates, where the actual causal factors are sleep, diet and exercise.

In this paper they focus on inflammation.

Since reddit has a hard on against, sleep, diet and exercise here are a few relevant studies demonstrating the link to depression.

​

>Aerobic exercises, including jogging, swimming, cycling, walking, gardening, and dancing, have been proved to reduce anxiety and depression.3 These improvements in mood are proposed to be caused by exercise-induced increase in blood circulation to the brain and by an influence on the hypothalamic-pituitary-adrenal (HPA) axis and, thus, on the physiologic reactivity to stress.3 This physiologic influence is probably mediated by the communication of the HPA axis with several regions of the brain, including the limbic system, which controls motivation and mood; the amygdala, which generates fear in response to stress; and the hippocampus, which plays an important part in memory formation as well as in mood and motivation.

This is false. Depression is linked to exercise, sleep, and diet but they are don't cause major depreesion. You can have great sleep, diet, and exercise habits and still develop major depression which increases your inflammatory markers. I actually had a case of major depression that popped up and my inflammatory markers were high even though I was in excellent shape. Major depression can increase inflammation regardless of your habits. Lesser forms of depression can get better with or even treated with working out and better sleep but not major depression.

platelet-to-lymphocyte ratio is one of the biomarkers for inflammation. Exercise, sleep, and diet don't affect that ratio. Only major depression does. Your assumptions are wrong here.

It doesn't mention the type of depression and it only REDUCES not completely treats major depression. It has to be completed treated not just reduced to a lesser degree of depression. Meds are necessary for treatment. Like wise you post a bunch of stuff and are too illeterate to know that it shows that exercise is good but isn't a cure all. Meds are needed in many cases especially for major depression due to chemotherapy. You sound like you're playing doctor. right now.

>University of South Australia researchers are calling for exercise to be a mainstay approach for managing depression

Manages. Not cures or treats.

>In conclusion, PA is effective for improving depression and anxiety across a very wide range of populations.

Improves depression and anxiety, does not cure or treat.

>Sleep, exercise and depression are all linked to brain volume

Linked doesn't mean anything. Poverty is also linked to lack of sleep, depression, and exercise. I'm surprised you haven't pushed hustle culture BS here too.

>Exercise has massive effects on mitochondria, which might be partly a mechanism in relation to depression.

Linked just means it appears in relation to. We don't know the cause or what the true fix is. But the best medical practices is talk therapy alongside medication as needed.

The fact you conflate proper sleep with insomnia is stupid. You can't "proper sleep habits" your way out of clinically diagnosed insomnia. It doesn't mean "goes to bed late".

The fact that you would post stuff that doesn't prove your point and yet be too illiterate to understand what you are reading is wild

I agree

>Lesser forms of depression can get better with or even treated with working out and better sleep but not major depression.

In your post you keep on referring to different forms of depression.

Major depressive disorders is just the name for basic normal depression. All the other types are worse or specialist types of depression.

Seems like exercise does acutely effect the ratio.

Again major depression is the normal basic depression everyone is talking about. If it was some other type they would specify.

The current view is nothing "cures" depression. So pretty much every study will just talk about treating it.

Sure people can use meds. It's like when I cut myself, I might take a painkiller. While it isn't fixing the underlying issue, it does help.

​

>The fact that you would post stuff that doesn't prove your point and yet be too illiterate to understand what you are reading is wild

You are the one who thinks that "major" depression is like some super duper serious form of depression, rather than just the medical name for basic clinical depression.

You are the one who doesn't know that every study on depression treatment will just talk about treating it rather than curing it.

could the inflammation be causing the person to feel depressed, or is it vice versa?

Actually you do. Major depression causes your lymphocytes to increase with relation to platelets. Meaning that you're more susceptible to cardiac events and general illness with major depression. The fact that major depression occurs in cancer patients could point to a host of issues. I would expect to see link between cancer spread and major depression.

This is opposed to less severe forms of depression that do not affect your lymphocytes and platelet ratio.

So yes. We do need scientists to figure this out.
