Essential information about mental disorders is a necessity because they help us to take preventive measures against the same and diagnose them in proper time. An in depth study of the causes, triggers, characteristics and symptoms of mental disorders play an effective role in leading a healthy life.

Bipolar Disorder Vs. Depression

A very common question which patients often ask their physician is- "What's the difference between bipolar disorder (also known as manic depression) and plain old depression?" The answer is very simple. Depression occurs in two instances- one when it occurs as a standalone disorder and secondly when it is a part of another disorder well known as bipolar disorder. It is up to your mental health care giver who will conduct adequate tests to determine whether depression is just depression or is a part of bipolar disorder.

Bipolar Disorder Includes Mania & Depression

Bipolar disorder mainly consists of two cycles in which the patient goes through two alternating cycles. One cycle is depression while the other is mania. The patient oscillates between the two cycles alternatively. It is also known as manic depressive depression.

What is a Mania?

Mania is actually a hyper excited state which can be said to have the following characteristics:

  • It includes a sense of exaggerated self-esteem and a feeling of grandeur.
  • Need for sleep decreases and one feels well rested after a 3 hours' sleep only.
  • Keeps on talking more than usual.
  • Patients seem to think that they have racing thoughts and hence experience a state known as flight of ideas.
  • Patients draw attention to irrelevant things.
  • Patients show psychomotor agitation and an increase in goal focused activities.
  • There might be an increase in involvement in pleasure filled activities that have a high possibility for painful outcome. For example, engaging in excessive buying activities, foolish business investments or sexual indiscretions, etc…

If more than three of such symptoms are present in a patient for a considerable period of time then he is said to be suffering from episodes known as manic episodes. If the episodes are not as severe as a manic episode then it is known as hypomanic episodes. To be categorized as a manic episode it has to last for at least a week, while to be termed as a hypomanic episode it needs to last for at least four days. If an individual shows signs of suffering from manic episodes and at the same time from alternating cycles of depression then he is said to suffer from bipolar disorder.

Depression has No Mania

However, ordinary depression patients do not suffer from anything even closely resembling mania. Major depression patients have no record of ever suffering from mania and hence they are identified as suffering only from depression. Some characteristics of depressive episodes are as follows-

  • Depressed mood is prevalent for nearly all the day and continues everyday
  • There is no pleasure or interest to be noticed in any activities nearly all the day and continues every day
  • There can also be noticed considerable weight gain or weight loss without dieting, and an increase or decrease in appetite.
  • They also suffer from hypersomnia or insomnia.
  • Psychomotor turmoil or retardation is also noticed on a daily basis
  • Fatigue is a prevalent factor
  • Thoughts of misplaced or excessive guilt or worthlessness
  • Decline in ability to think, concentrate and creativity problems
  • Repetitive thoughts of death and recurrent planning of suicide or lack of plan but still ideation of suicide.

If five or more of these symptoms are present for more than 2 weeks then the person is diagnosed as having depression. Lack of manic episodes qualifies the person as only having major depression.

Subjective report plays a major role in helping a mental health care professional to decide whether the person suffers from just depression or bipolar disorder. This is often referred to as "intake interview" or "initial evaluation" and his stage plays a vital role in gathering as much information as possible by the doctor. The more information a doctor can gather the more they can aid to conduct the correct diagnosis.

For example, if the person attends his first session and complains of depression then the psychologist will looks for hints to know whether he has suffered any manic episodes. If manic or hypomanic episodes were found, then they would be categorized into bipolar otherwise they would be categorized into suffering from major depressive disorder. However, the diagnosis primarily depends on the individuals' mental health history. There are many factors which will ultimately affect the correct diagnosis. The clinician will ask you the necessary questions to arrive at a proper conclusion.
