Bipolar disorder causes extreme shifts in a person’s moods, with recurring episodes of manic and depressive thoughts throughout their lives, although many are free of symptoms between these episodes.
The symptoms of manic behaviour include:
- An inability to focus or concentrate
- A continuous elevated or euphoric mood
- Inflated self-esteem
- Little need for sleep
The symptoms of depressive behaviour include:
- Change in appetite or body weight
- Self-harm and suicidal thoughts
- Feelings of guilt and worthlessness
- Difficulties in concentrating
Stressful life events or physical injuries as well as other factors can lead to the onset of symptoms of the illness.
A person can have symptoms of both mania and depression at the same time.
Psychotic behaviour may also be present during severe episodes of either mania or depression. This can include delusions and hallucinations.
