Current findings of studies are heterogeneous and lead to the conclusion that depression is more prevalent in women as well as that they have a higher risk for depression. Women express more typical depressive symptoms while men offer more atypical symptoms like aggressiveness, irritability, alcohol misuse which is constituted as male depression (MD).
