Depression: the facts

Mental illnesses are states of mind that affect mood, feeling, thinking, and behavior. They may be long-lasting (chronic), occasional, or they can affect the ability to relate to others and function on a daily basis. This article is going to cover one specific mental illness, depression. Depression is a widespread mental disorder that affects more than 264 million individuals of all ages worldwide. It is the leading cause of worldwide disability and a major purveyor to the burden of disease overall. Because of the enormity of depression, it is important to know about depression: the facts.

What is Depression?

Depression is a form of mental illness that is a mood disorder. It causes a perpetual feeling of sadness and loss of interest. Additionally called a major depressive disorder or clinical depression, it affects how one feels, thinks and, behaves, and can lead to a range of emotional and physical problems.

Death or a loss – Sadness or grief from the death or loss of a loved one, even if by natural means, can increase the risk of depression.

Abuse – Previous sexual, physical, or emotional abuse may increase the susceptibility to clinical depression later in life.

Certain medications – Certain drugs, for example, isotretinoin (used to treat acne), the antiviral drug interferon-alpha, and corticosteroids, can increase the risk of depression.

Conflict – Depression in an individual who has a biological susceptibility to develop depression may result from personal conflicts or disputes with friends or family members.

Genetics – A family history of depression can increase the risk. It is commonly thought that depression is a complex trait, which means that there are probably many different genes that each exerts minor effects, rather than a single gene that contributes to disease risk. The genetics of depression, as with most psychiatric disorders, are not as simple or straightforward as in solely genetic diseases such as Huntington’s chorea
or cystic fibrosis.

Key events – Even positive events such as starting a new job, graduating, or getting married may advance to depression. This can also include moving, losing a job or income, getting divorced, or retiring. Nevertheless, the syndrome of clinical depression is never just a “normal” response to stressful life events.

Serious illnesses – On occasion depression can co-exist with a major illness or may be triggered by another medical condition.

Additional personal problems – Problems such as social isolation because of other mental illnesses or being ostracized from a family or social group can contribute to the risk of developing clinical depression.

Types, Symptoms, and Treatment of Depression

Everybody feels down from time to time, but should an individual feels that way most of the time and it affects their daily life, chances are he or she may have clinical depression.

There are several different types of depression. Events in one’s life can cause some, and chemical changes in the brain can cause others. Therefore, it takes a specialist to determine which type of depression an individual may have and the best course of treatment.

Major Depression (major depressive disorder) – An individual who feels depressed most of the time for a majority, or all of the days of the week may have this type.

Some other symptoms might include:

  • Being tired and without energy

A physician may diagnose a patient with major depression if the individual has five (5) or more of these symptoms on most days for 2 weeks or longer. At least one among the symptoms must be a depressed mood or loss of interest in activities.

Treatment for major depression:

Meeting with a therapist can be of assistance. One can also meet with a mental health specialist who will assist in finding ways to manage the depression. Medications known as antidepressants can also be helpful.

When medication and therapy are not working, other options the physician may suggest are:

  • Transcranial magnetic stimulation (TMS)
  • Electroconvulsive therapy (ECT)
  • Vagus Nerve Stimulation (VNS)

ECT makes use of electrical pulses, TMS uses a unique type of magnet, and VNS makes use of an implanted device. All are designed to accelerate particular areas of brain activity. This assists the parts of the brain that control one’s mood to work better.

Dysthymia (mild, chronic depression) – Dysthymia is less critical and doesn’t have as many symptoms as major depression. On the other hand, the symptoms can linger for a longer period of time, often two years or Depression: the facts - Dysthymialonger. Individuals who suffer from dysthymia can additionally experience periods of major depression–sometimes known as double depression. In modern diagnostic classification systems, dysthymia and chronic depression are now both mentioned to as clinical depression disorder.

The symptoms of dysthymia are the same as major depression but fewer in number and not as intense. They include the following:

  • Being physically restless or rundown in a way that is noticeable by others
  • Exhaustion or loss of energy almost daily

Atypical Depression – Atypical depression is a subtype. It can be an “identifier” for either major depression or dysthymic disorder. Individuals with atypical depression have usually experienced depression initially at an early age, during their teenage years.Depression: the facts - Atypical

Despite its name, atypical depression is extremely widespread. It is compared with “melancholic” depression, another subtype of depression that involves symptoms of insomnia (as opposed to oversleeping), loss of appetite (as opposed to increased appetite), a comparative lack of mood reactiveness to environmental circumstances, and a strikingly diminished ability to feel pleasure.

One of the main characteristics of atypical depression that differentiates it from melancholic depression is mood reactivity. In other words, the individual with atypical depression will see their mood improve if something positive occurs. On the other hand, with melancholic depression, positive changes will seldom yield a change in mood. Additionally, diagnostic standards call for at least two of the following symptoms to accompany the mood reactivity:

  • Having a feeling of being weighed down, paralyzed, or “leaden”
  • Having a more intense reaction or increased sensitivity to rejection, resulting in problems with social and work relationships
  • Increased appetite or weight gain
  • Sleeping too much (hypersomnia)

With that condition, having low levels of thyroid hormone can lead to indicators that include depression and weight gain.

Treatment for atypical depression

Physicians are most likely to recommend psychotherapy (talk therapy) and/or medications for atypical depression, depending on the seriousness of the symptoms. There are various types of psychotherapy and medications available for treatment. An individual may be directed to a specialist such as a psychiatrist, psychologist, or other licensed mental health professional for treatment.

Postpartum depression is linked to chemical, social, and psychological changes that happen when having a baby. The term describes a range of physical and emotional changes that many new mothers experience. PPD can be treated with medication and counseling.

The chemical changes involve a rapid drop in hormones after delivery. The actual link between this drop and depression is not clear.

A woman can have these conditions and depression at the same time.

Treatment for postpartum depression

Postpartum depression is treated differently depending on the type and intensity of a patient’s symptoms. Treatment options include anti-anxiety or antidepressant medications, psychotherapy, and involvement in a support group for emotional support and education.

Also, depressive periods can be more harmful and harder to treat than in individuals who never have manias or hypomanias.

The seriousness of mood incidents can range from vastly mild to extreme, and they can happen slowly or suddenly within a period of days to weeks. When discrete mood incidents happen four (4) or more times per year, the succession is called rapid cycling. Rapid cycling should not be confused with very frequent moment-to-moment changes in mood, which can occasionally happen in individuals with bipolar disorder or other conditions such as borderline personality disorder.

Seasonal Depression (Seasonal Affective Disorder—SAD) – Seasonal depression is a mood disorder that occurs annually at the same time. An uncommon form of seasonal depression, known as summer depression, begins in late spring or early summer and ends in fall. In general, the seasonal affective disorder commences in fall or winter and terminates in spring or early summer.Depression: the facts - Seasonal Affective Disorder [SAD]

While the specific triggers of SAD are not known, some scientists believe that certain hormones produced deep in the brain trigger attitude-related changes at certain times of the year. Experts believe that SAD may be linked to these hormonal changes. One (1) of several theories is that reduced sunlight during the fall and winter seasons leads to the brain generating less serotonin, a chemical linked to the brain pathways that control mood. When nerve cell pathways in the brain that regulate mood do not perform normally, the result can be feelings of depression, along with symptoms of fatigue and weight gain.  For more information serotonin, please read the article, Serotonin: the facts on this website.

SAD usually begins in young adulthood and is more widespread in women than men. Some individuals with SAD have mild symptoms and feel out of sorts or irritable. On the other hand, others have worse symptoms that interfere with relationships and work.

Due to the fact that not enough daylight during wintertime is related to SAD, it’s less often found in countries where there’s plenty of sunshine year-round.

  • Weight gain

Summer Symptoms

  • Trouble sleeping
  • Weight loss

Treatment for SAD

There are diverse treatments, depending on the seriousness of symptoms. Also, if an individual has another type of depression or bipolar disorder, the treatment may be different.

Conventional antidepressants are frequently employed to treat seasonal depression. Bupropion XL is presently the only medication that is FDA-approved explicitly to prevent major depressive episodes in people with SAD.

Many physicians advise that people with SAD get outside early in the morning to get more light that is natural. If this is not possible for the reason of the dark winter months, antidepressant medications or light therapy (phototherapy) may help.

Psychotic Depression – Psychotic depression is another subtype of major depression that takes place when a severe depressive illness includes some form of psychosis (a condition that causes one to lose touch with reality).

The psychosis can be hallucinations (such as someone hearing a voice Depression: the facts - Psychotic Depressiontelling them that they are worthless and no good), delusions, or some other break with reality. They may also have strange and illogical ideas. Psychotic depression affects roughly one (1) out of every four (4) individuals admitted to the hospital for depression.

Antipsychotic drugs affect the neurotransmitters that permit communication between nerve cells in areas of the brain that control our ability to comprehend and manage information regarding the world around us. There are numerous antipsychotic, or neuroleptic, medications used regularly today. Each drug has distinctive side effects and may differ in its clinical efficiency profile. However, these drugs are better tolerated than the antipsychotics of the past.

Treatment for psychotic depression is very successful. Individuals are generally able to recover, usually within several months. However, continual medical follow-up may be needed. If the medications are unsuccessful in ending the psychosis and depression, occasionally electroconvulsive therapy (ECT) is used. It is crucial for the patient to work closely with the physician to find the most effectual drugs with the least amount of side effects, because psychotic depression is quite serious, and the risk of suicide is great also.

Treatment-Resistant Depression – Regrettably, depression treatments do not work always. As much as two-thirds of individuals with depression are not helped by the initial antidepressant they try. Up to a third, do not respond to many attempts at treatment.

Treatment-resistant depression (TRD) can leave one feeling despondent and disheartened. Months or even years can go by with no relief. In addition, after considering the effort it took to get help, it can be demoralizing with no sign of getting better.

However, there is hope. It is simply an issue of finding the right approach. This can include different drugs, therapy, and other treatments.

It is important to note that untreated clinical depression is a critical problem. Left untreated depression increases the chance of dangerous behaviors like drug or alcohol addiction. It can also ruin relationships, cause problems at one’s place of work, and make it challenging to overcome serious illnesses.

If you or someone you know is suffering from depression, you or they must get help as soon as possible.
