The relationship between brain-derived neurotrophic factor (BDNF)and bipolar disorder can best be described as:
A)strong - BDNF gene variation predicts bipolar disorder
B)inconsistent - BDNF gene variation predicts bipolar in some but not all ethnicities
C)nonexistent - BDNF gene variation has been linked to depression but not bipolar
D)weak - BDNF gene variation only sometime predicts one type of bipolar disorder (i.e., rapid cycling)

Question

Quizplus · Accepted Answer

The relationship between BDNF gene variation and bipolar disorder has shown inconsistency across different studies, with some research indicating a link in certain ethnic groups but not others. This suggests that while there may be a connection, it is not uniformly observed across all populations, highlighting the complexity of genetic factors in bipolar disorder.
