What Causes Bipolar Disorder

Bipolar disorder is one of the most commonly seen mental disorders in people of all age groups. Also known as manic depression, bipolar disorder is characterized by frequent mood swings, depression and mania. Though studies of various kinds have been conducted to arrive at the exact causes for bipolar disorder, significant success has not been achieved in this regard yet. The present opinion among experts is that the bipolar disorder seen in a person is due to a combination of various biological and physiological reasons. It is to be noted here that the genetic or the biological causes are the prime reasons for the occurrence of this kind of disorder in a person.

The very fact that if one of the twins is affected by  this disorder, there are 80 percent chances that the other twin ( in case of identical twins) suffers from the same disorder, goes on to show that the bipolar disorder can be inherited genetically. Also, it has been found that the first degree relatives of a patient who has been diagnosed for bipolar disorder are more prone to other psychiatric disorders. Thus, the experts conclude that genes have a role to play in the inception of bipolar disorder in a person. In some other patients who have been diagnosed for bipolar disorder, it has been found that the improper structure of the brain is the causative for this problem.

The environmental factors that induce bipolar disorder in a person are drug addiction and alcohol abuse. The impact on a child who lives in an environment where physical abuse is seen very often is very high and this might lead to the child showing symptoms of bipolar disorder in the longer run. However, it is to be noted that the onset of the disease might be after a continuous exposure to such disturbing environment. The study that has been conducted on patients who have been diagnosed for this ailment forms the base for this inference.

The physiological cause for bipolar disorder is the chemical imbalance within the brain of the person who suffers from this ailment. Experts are of the opinion that when the levels of a neurotransmitter called norepinephrine are lower than normal, the patient goes into depression and when the levels exceed the normal state; a state of mania is reported in the patient.

With the right kind of diagnosis and medication, bipolar disorder can be cured completely. However, the main threat for a patient who suffers from this ailment is his unstable mind, which might lead to suicide attempt when he is in a state of depression and this situation needs to be avoided by keeping a close watch on him always.
