All About Depression
Depression is commonly characterised by a persistent mood of depression, lack of interest in various activities, and other symptoms that can cause impairment in daily life. It can be caused by a combination of social, psychological, as well as biological factors. It can also be hereditary. Research suggests that it is caused by changes in the brain’s function, to the extent of altered activity of some of the brain’s neural circuits.
Depression doesn’t look like just one thing. There are a lot of symptoms to watch out for if you think that you or someone else is going through depression. Here are a few most common symptoms that you can find, note that this is not an exhaustive list.
Hopelessness
Major depression is considered a mood disorder that can affect the way a person feels about life. Having an outlook of hopelessness or helplessness is known as one of the most common symptoms of depression. Other feelings to keep an eye out for are worthlessness, inappropriate guilt, or even self-hate. Some recurring phrases that a person may say, then would be those of self-blame and asking what the point of life is.
Loss of Interest
Depression can result in a lack of interest or motivation or even withdrawal from things a person once took pleasure in or enjoyed doing. It can be anything like going out with friends, hobbies, sports, etc.
Fatigue and Sleep Issues
Many times, people stop doing what they used to enjoy because of the lack of energy. Overwhelming fatigue can lead to excessive sleeping. Other times, it may also result in insomnia, making an unending cycle. Lack of rest can even lead to anxiety.
Anxiety
It hasn’t been proved that depression causes anxiety, but very often, those two occur together. The symptoms here can look like feelings of panic and dread, rapid breathing or heart rate, trouble focusing or thinking about anything other than what is causing anxiety.
Irritability
This is one symptom that is many times ignored or is delegated to men only, when in fact, this is a symptom that affects whoever has depression. Irritability, risky or escapist behaviour, and even substance abuse factors in as symptoms of depression.
Appetite and Weight
Both the factors can easily fluctuate, and they can be different for different people. Some may gain weight with an increased appetite or lose weight with the loss of an appetite. An indication of whether this is linked to depression can be whether it is intentional or not. If not, it would probably be linked.
Uncontrollable Emotions
One moment a person could be crying bitterly and be extremely angry the next with no noticeable outward reason for it. This means that depression can result in mood swings.
Death
Suicidal thoughts and suicide is very often linked with depression. Often people talk about it or self-harm before actually committing the act. Keep an eye on anyone you think may be at risk.
Sudden Celebration
Often, before committing suicide, people may throw a party or hold some festivity of some sort as a final going-away gift for those they love.

Types of Depression
As mentioned before, depression is not indicated in the same way by everyone. Here are the types of depression that people go through.
Major Depression
Chronic Depression (Dysthymia)
Atypical Depression
Postpartum Depression
Bipolar Depression (Manic Depression)
Seasonal Depression (SAD)
Psychotic Depression
Treatment-Resistant Depression
Treatment
It is difficult to live with depression, but there is the availability of treatment to help people. Treatment can differ from person to person and doctor to doctor, depending on what the doctor feels best. Please note that not all doctors or therapists can give the care and treatment that is needed. Therefore, it is best to try again with another doctor until you get the help that you need. Your doctor may suggest a different combination of treatments like lifestyle therapy and medical treatment.
Medication
You may be prescribed antidepressants, pills for anxiety, antipsychotic medication, sleeping pills, etc. Each one depends on the diagnosis and the patient. Each medicine has its own potential risks, which is why self-medication is not a good idea.
Psychotherapy
Meeting a therapist regularly can help cope with intense emotions in a healthy manner. Often group or family therapy can also help. Thirty minutes of exercising a few times a week are usually recommended in this case.
Exercise
Exercising can help increase the production of endorphins that can improve one’s mood.
Avoid Alcohol and Drugs
Drugs and alcohol can provide temporary relief but can aggravate the symptoms of anxiety and depression worse in the long run.
Learn to Say No
Setting firm professional and personal boundaries can eliminate the feeling of being overwhelmed and can also provide relief from toxic circles of people that are around them.
FAQs on Depression Symptoms
1. What is clinical depression from a biological and psychological perspective?
Clinical depression is a serious mood disorder characterised by a persistent feeling of sadness and a loss of interest in activities. From a biological perspective, it is linked to changes in brain function, including altered activity in neural circuits and an imbalance of key neurotransmitters like serotonin, norepinephrine, and dopamine. Psychologically, it impacts how you feel, think, and behave, leading to significant emotional and physical problems that can interfere with daily life.
2. What are five primary symptoms of depression to be aware of?
While symptoms can vary, five primary indicators often point towards depression. These include:
- Persistent Sadness or Hopelessness: A constant low mood, feelings of worthlessness, or an outlook that things will never get better.
- Loss of Interest or Pleasure: A noticeable lack of enjoyment in hobbies, social activities, and other things that were once pleasurable (a condition known as anhedonia).
- Significant Changes in Sleep and Appetite: This can manifest as either insomnia (inability to sleep) or hypersomnia (excessive sleeping), along with a loss of appetite and weight loss, or increased cravings and weight gain.
- Overwhelming Fatigue: A severe lack of energy that isn't relieved by rest, making daily tasks feel exhausting.
- Difficulty Concentrating: Trouble focusing, making decisions, or remembering things, which can affect academic or professional performance.
3. What are the main types of depression recognised in health studies?
Depression is not a single condition; it manifests in several forms. Some of the main types include:
- Major Depressive Disorder (MDD): Characterised by a combination of symptoms that impair the ability to work, sleep, study, and enjoy life.
- Persistent Depressive Disorder (Dysthymia): A chronic form of depression where a depressed mood lasts for at least two years, with symptoms that may be less severe but are long-lasting.
- Bipolar Disorder: A condition involving extreme mood swings that include emotional highs (mania or hypomania) and lows (depression).
- Seasonal Affective Disorder (SAD): Depression that occurs during specific seasons, typically starting in the late fall and continuing into the winter months.
- Postpartum Depression: A severe, long-lasting form of depression experienced by some women after giving birth.
4. How is anxiety related to depression?
Depression and anxiety are distinct conditions, but they frequently occur together. Many people with depression also experience symptoms of anxiety, such as nervousness, a sense of panic or dread, rapid heart rate, and trouble focusing. Biologically, both disorders may share underlying vulnerabilities, including similar genetic factors and dysregulation in the same neural circuits and neurotransmitter systems in the brain. The overwhelming fatigue from depression can also trigger anxiety, creating a difficult cycle.
5. What are some effective treatments and lifestyle changes for managing depression?
Managing depression typically involves a combination of professional treatment and lifestyle adjustments. Psychotherapy, or talk therapy, helps individuals develop healthy coping strategies. Medical treatments may include prescribed antidepressants to help balance brain chemistry. Recommended lifestyle changes include regular exercise, which boosts mood-improving endorphins; maintaining a healthy diet; avoiding alcohol and drugs, which can worsen symptoms; and establishing strong personal and professional boundaries to reduce stress.
6. Why does depression often cause physical symptoms like fatigue and changes in appetite?
Depression is not just an emotional state; it is a systemic condition that profoundly affects the body's physiology. The physical symptoms are caused by its impact on the brain's regulatory functions. For example, depression can disrupt the hypothalamus, a brain region that controls appetite and sleep cycles. It also affects neurotransmitters like serotonin and norepinephrine, which are crucial for regulating both mood and energy levels. This disruption leads to the overwhelming fatigue and significant changes in weight and appetite commonly seen in depressed individuals.
7. How can one differentiate between temporary sadness and clinical depression?
The key difference between sadness and clinical depression lies in duration, intensity, and impact. Sadness is a normal human emotion that is a temporary reaction to a difficult situation. It typically fades with time. In contrast, clinical depression is a persistent mental health disorder where feelings of emptiness and despair last for at least two weeks and are intense enough to significantly interfere with one's ability to function in daily life, including school, work, and relationships, often without a specific trigger.
8. What is the role of neurotransmitters in the biology of depression?
Neurotransmitters are chemical messengers in the brain that play a vital role in regulating mood. In depression, there is often a believed imbalance in key neurotransmitters. The most commonly cited is serotonin, which helps regulate mood, sleep, and appetite. Low levels are strongly associated with depressive symptoms. Other important neurotransmitters include norepinephrine, which influences alertness and energy, and dopamine, which is related to feelings of pleasure and motivation. Many antidepressant medications work by helping to correct the imbalance of these crucial brain chemicals.
9. Can depression be hereditary, and what is the influence of genetic factors?
Yes, research suggests that depression can have a genetic component, meaning it can run in families. While there is no single 'depression gene,' individuals can inherit a genetic predisposition that makes them more vulnerable to developing the disorder. However, genetics alone do not determine one's fate. Environmental factors—such as trauma, chronic stress, or significant life changes—often act as triggers that activate this underlying vulnerability. Therefore, depression is typically caused by a complex interaction between a person's genetic makeup and their life experiences.
