Why Is This Important?

Bipolar disorder, formerly called "manic depression," is a  psychiatric condition characterized by extreme swings of mood over time, from an energized, unrealistic, and euphoric state of mind to severe depression and back again.  Children with autism spectrum disorders often have volatile moods, including extreme irritability that sometimes leads to "meltdowns."  Researchers want to find out whether issues of mood disturbance occur in families who have a child with an ASD.  To what extent are such traits found in children with ASDs, their parents, and siblings?

Data from IAN Research:

Pie chart showing the percentage of unaffected siblings who have been diagnosed with or treated for bipolar disorder.

This chart shows that 1% of all siblings taking part in IAN Research, at some time in their lives, have been diagnosed with or treated for bipolar disorder.

Pie chart showing the percentage of unaffected siblings aged 10 to 18 who have been diagnosed with or treated for bipolar disorder.

This chart shows that 3% of siblings aged 10 to 18 taking part in IAN Research, at some time in their lives, have been diagnosed with or treated for bipolar disorder.  (It is important to consider older children especially, since they are more likely to have experienced various issues than younger children.)
