Bipolar disorder is a mood disorder that is classified by cyclic episodes of extreme highs and lows. The condition is sometimes called manic depressive disorder. There are different types of bipolar disorder. According to the National Institute of Mental Health, bipolar I disorder is composed of mostly manic or mixed episodes that last at least seven days. Depressive cycles can last two weeks. These episodes interfere with the individual's ability to function and deviate from their normal temperament.
Sleep Changes
Those in a manic phase of bipolar type 1 disorder might exhibit an alteration in their sleep patterns. Since the mania associated with the disorder produces a feeling of energy and euphoria, those in this phase often seem to require little or no sleep. They might stay awake in an attempt complete tasks that they have created for themselves. They might continue to appear energetic, despite a lack of sleep.
Impulsivity
During episodes of mania, those with bipolar type 1 might engage in dangerous and reckless behaviors. They might seek pleasurable activities with little thought about the consequences of risky behavior, such as increased sexual activity or gambling. The consequences from the impaired judgment exhibited by the individual, however, could affect him or his family long term. It is important to be aware of any reckless behavioral deviation in individuals suffering with the disorder.
Additions Behaviors
Those in the manic phase of the disorder often take on more projects or tasks than they are capable of completing. In addition, they often jump from one task to another since they are easily distracted and tend to be unfocused. Conversations may be difficult to follow since most of these individuals experience racing thoughts that can affect their communication.
Depressive Behaviors
People with bipolar type 1 disorder also experience episodes of depression. During this cycle, they may be plagued with feelings of loneliness, hopelessness and even suicidal thoughts. They also exhibit behaviors that usually differ greatly from those in the manic phase. During episodes of depression, individuals may become socially withdrawn, lose interest in activities, sleep excessively, or become increasingly irritable or agitated. It is important to pay attention to the symptoms and behaviors during this phase. Thoughts of death or suicide should be reported immediately.
