180,000 Hongkongers may have bipolar disorder and not know it
As many as 180,000 people in Hong Kong could be suffering from bipolar disorders that may have been misdiagnosed as normal depression, says an academic.
The medical community has only recently paid greater attention to bipolar disorders after a more systematic classification for psychiatric conditions was agreed on by experts.
The disorder, which lies in between normal and extreme forms of depression, has more serious symptoms than normal depression.
Sufferers run a greater risk of committing suicide and suffer mood swings more frequently.
Sometimes they experience prolonged insomnia and are over-energetic, confident and talkative, while other times they feel exhausted and lack the drive to meet people or go outdoors.
'The mood fluctuation is like spending half the day in paradise and then falling down back into hell for nine and a half days,' said Lee Sing, head of the mood disorders centre at Chinese University.
