Depression vs Bipolar disorders:Complete guideline

Depression vs Bipolar Disorder: In order to clarify the mentioned differences it is necessary to examine each of the concepts within the general framework of the models and the kind of information which can be derived from each of the definitions.

For example, depression and bipolar disorders are also another type of mental health disorder that is rather hard to comprehend and is similarly common among many people. Therefore despite the several similarities that major depressive disorder and Bipolar Disorder have, the two disorders are also characterized by distinct features. Such differences are critical in determining the various approaches that would be useful in diagnosing the disease or/and its treatment.

Defining Major Depressive Disorder

The worst type of mood disorder could be the Major depressive disorder often referred to as clinical depression because the lasting period is weeks or even months, and the symptoms involve everyone from sadness, hopelessness, worthlessness, and lack of interest in pleasure and hobbies that the affected individual once considered enjoyable. Additional common symptoms of a major depressive episode include:The other symptoms that may be present when diagnosing a major depressive episode include:

– Tiredness and limp spirit

– Cognitive deficit which may manifest as poor focus and weakness in remembering events.

– This can be insomnia or oversleeping.

– Loss of appetite and alteration in weight

– Suicidal thoughts

The manifestation of these symptoms lasts for two weeks or more and the individual is likely to experience significant functional impairment or subjective distress. Depression can be extensive or mild depending on the level of symptoms it has and the extent to which they are felt. MDD is generally defined as the presence of at least five depressive symptoms during the same two week period.

This makes depression to be described as episodal in that a person may only get depressed at a certain time in their life but this may be separated by other times of normal functioning. However, some have chronic depression where the patient suffers from depressive symptoms, mostly persistent, for two years or more.

Understanding Bipolar Disorders

Bipolar disorder also is defined by extreme mood swings and fluctuations in energy, enthusiasm, and activity. Bipolar II disorder is different from the other types of bipolar disorder in that the separate episodes are hypomanic rather than manic.

In Mania, there are features of heightened mood whether elevated or irritable mood, increased energy, increased rate of speech, impulsivity, and excessive participation in risky activities. In Mania there are either elevated or irritable moods, increased energy, increased frequency of speaking, impulsivity and increased engagement in high-risk behaviors. Hypomania can be described as harboring mania symptoms that have a relatively lesser effect on a person as compared to the mania state. Additional common symptoms during manic or hypomanic phases can involve:Other symptoms that might occur especially during the manic or hypomanic episodes include:- They require less sleep as compared to the normal or standard requirements of human beings.

– Racing thoughts

– Distractibility

-Taking part in risky pleasurable activities

For a manic episode, there is an increased mood, activity/energy that is expansive or irritable for at least a week and causing marked distress in the functioning of life.

Bipolar depression as they name suggests has the normal symptoms of depression such as loss of interest, changes in appetite, energy issues, cognitive impairment, and hopelessness. However, bipolar depression is not a stable state as it will still switch between periods of abnormally elevated mood.

Types of Bipolar Disorder

There are several specific bipolar disorder diagnoses:There are several specific bipolar disorder diagnoses:

Bipolar I Disorder entails that there is a presence of clear manic episodes that follow depression. The single-episode mania has to be a minimum of 7 days or cause the hospitalization of the patient.

In Bipolar II Disorder, the mood swings consist of hypomania instead of regular mania and are followed by periods of depression.

-Cyclothymic Disorder is defined as a chronic and persistent swing of hypomanic and depressive symptoms that do not reach the severity of hypomanic or major depressive episodes. – Other Specified and Unspecified Bipolar Disorders are used to describe symptoms which may cause distress but do not reach the severity to be classified in the listed categories. Depression and bipolar disorder share some of the same symptoms and are also treated by similar medications. However, as bipolar disorder does include the existence of depressive episodes, there is partial symptom overlap with unipolar depression

. Both conditions can involve:

– Depression, frequent crying, low self-esteem

– Lack of energy and tiredness

– Sleep disturbances

– Appetite/weight changes

– Concentration challenges

– Ideas of committing Suicide (more frequent in bipolar depression than in mania)

Also, the risk factors and comorbid conditions, such as other anxiety disorders, substance use disorders, thyroid disorders, obesity, diabetes, heart disease, and so on are similar to depression and bipolar disorder. Mental health is also affected because childhood adverse experiences, including traumatic ones, and stressors are associated with chronic diseases and mental illnesses. Search results Some of the causes that have been considered in bipolar disorder and depression include; Genetics. Schizophrenia is a heritable disorder while bipolar disorder is moderately heritable the relative risks from parental schizophrenia is lower around 40- 50 % in case of schizophrenia while the same is around 60-80% in case of bipolar disorder. In this case, it would be possible to mistake depression and bipolar disorders to be similar given that the main feature of both conditions is depression, though there are certain elemental differences between the two. While unipolar depression and bipolar illness can look similar during depressive episodes, there are critical ways in which the conditions differ:So although unipolar depression and bipolar illness may be indistinguishable in the depressed state the two are in actual fact different in the following ways:

Mood Episode Timeframes

Depression is usually characterized by longer periods of depression than bipolar disorder. Bipolar depression occurs for several weeks to several months and occurs between manic or hypomanic episodes or mixed symptoms, whereas major depression may persist for months or years without manic or hypomanic symptoms.

Mood Quality

Mania is a core feature of bipolar disorder and it is distinctly different from depression in that it includes periods of elevated, elated mood, pressure to talk, increase in goal-directed behavior, and other such features..This is another piece of work that demonstrated that patients are more irritable in mania than they are euphoric, and they have more bipolar as opposed to unipolar depression.


While psychotic symptoms are present in some patients with depression, they are psychotic symptoms in the form of paranoid or persecutory beliefs or hallucination, full blown psychosis is more characteristic for bipolar I disorder during severe mania or depression. Data shows that roughly 50% of the bipolar I patients manifest psychotic features during mood episodes.

Seasonal Pattern

Some subjects with depression exhibit more seasonal changes and their symptoms are severe during the period of reduced exposure to light in the fall and winter seasons. Bipolar episodes are generally not as related to the seasonal light/dark changes.


Studies have found the genetic/biological factor to be stronger in bipolar illness, whereas biological factors are less influential in unipolar depression as compared to psychological factors like trauma, stress and cognitive patterns. It can be presumed that there are probably many other environmental factors that may precipitate depression in the genetically vulnerable individuals.

But it is noteworthy that in many cases, family  history and genetics are the main reasons for developing such diseases. There are specific genes concerning serotonin and dopamine pathways that have a positive association with depression and bipolar disorder. It also reveals that bipolar disorder and major depression have partial genetic overlap with schizophrenia and autism spectrum disorder – that is, there are biological connections between mood and behavioral disorders.


Both unipolar and bipolar depression share a common class of medications targeting the same neurotransmitter such as serotonin reuptake inhibitors. However, medications used in this disorder MUST be different during the manic phase than during the depressive phase for worsening of the disorder. Lithium and anticonvulsant medications or antipsychotics show efficacy in bipolar mania, while SARDs without mood stabilizers have the potential to induce mania in bipolar I.

Both illnesses require talk therapy and psychosocial support but depression aims at reorganization and changing of thought patterns while bipolar disorder puts more focus on stability of mood and cycles. Recurrent major depressive disorder is managed by preventing depressive relapse while early identification and intervention of manic relapse in bipolar illness by use of mood charting is paramount.Medications

This is because, being complex moods changes that take place in the brain, prescription medicines help in providing this balance.

For depression:

– SSRIs: Tables of antidepressants, such as Zoloft, Lexapro

– SNRIs: such as Cymbalta, Effexor – it is a serotonin, norepinephrine reuptake inhibitor.

– Atypical antidepressants: Remeron, Wellbutrin and others

For bipolar disorder:

– Mood stabilizers: Lithium–anticonvulsant drugs

– Atypical antipsychotics: Seroquel Zyprexa

– Anti-anxiety medications

Health treatment therefore entails the identification of the right drugs which will have minimal side effects for the patients through constant assessment of the effectiveness and dose variation. Therapies and medications combined significantly alleviate bipolar as well as depressive episodes.


Both conditions require working with a licensed therapist on a weekly or biweekly basis. Psychotherapy helps patients understand how to handle illnesses, manage life problems and avoid relapse. Common therapy approaches include:

– Among them, it is possible to highlight cognitive  behavioral therapy (CBT).

– Interpersonal therapy (IPT)

– Psychoeducation

– Family-focused therapy

– Group therapy

Psychotherapy with support increases the sense of emotional well-being to foster the necessary change appropriate for chronic mood disorders.

Lifestyle Changes

Lifestyle changes in patterns of behavior help set the framework of regularity that aids mood stability and overall health. Common recommendations include:

– Stress reduction approaches – yoga, meditation, and conscientious breathing.

– A balanced diet with good intake of foods that have rich nutrients, regular exercise, and ample rest.

-.Eating the right kinds of food and intake of omega-3 fatty acids that are healthy for the brain.

– Alcohol and any kind of recreational substances should under no circumstances be taken.

– This is as far as adhering and following up with the prescribed medications are concerned.

– It should be possible to use additional light containing boxes during the winter.

Online post-illness groups, peer support communities, and mental health mobile applications are also helpful in managing the lifestyle and preventing relapse.

Early Intervention and Integrative Care

It simply means that early identification of the conditions alongside maintaining the patient on proper medication and other therapies heightens the chances of effectively handling the disorders of depression and bipolar. The care plan which is individualized is ideal in enhancing positive impacts since it embraces a dual approach of physical and emotional health needs in the process of maintaining health.

Bipolar depression VS unipolar depression

As it will be indicated that depressive symptoms are similar to those of depression and bipolar, it is crucial to diagnose the problem before going ahead with treatment. Bipolar disorder is typically difficult to diagnose as patients present themselves for medical help during the depressive phase, while the manic phase does not present as ‘feeling high’ or ‘up’ in a normal sense of the term. Manic denial leads these bipolar II patients to ten years of misdiagnoses of unipolar depression before switching to bipolar II.

They use specific criteria for differentiating bipolar depression from MDD; for instance, they inquire about past hypomanic or manic episodes concerning elevated behaviors. They get details from partners and family that may have observed past manic symptoms which the patient cannot recall or deny. Depression is not the cause of clear manic episodes that have been seen in the past, which must imply bipolar illness.

Custom diagnoses are made according to the criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) by the American Psychiatric Association. The prevalence of bipolar II disorder is often missed in the initial diagnosis with levels up to 75% diagnosed with only depression, so effective screening tools and decision aids enhance accuracy.


In summary, while depression and bipolar disorders are both genetic in nature and may present with some similar symptoms such as the depressive episode, they have significant differences in terms of the manic activity, psychosis risk and seasonality, causes and management. These two core symptoms; distinguishing between these complex mood conditions of low mood patterns and the changes in sleep, energy, thoughts and behaviours ensure the correct diagnosis and treatment plan is provided.
