Hi. My son (Bipolar III, clozapine, 19 years old) tends to get manic during the winter. We live in North Dakota. Bipolar literature always says bipolars get depressed in fall and winter and manic in spring and summer but with my son it seems to be the opposite. He starts to show signs of mania in late October and by March it's full blown. Can anybody relate to this or offer a different opinion. Thanks.
