This Is For My Husband. He Goes Through A Funk

This is for my husband. He goes through a funk around once a month and it last for 4 to 5 days. He can not stay awake. He has no memory of these days. He is normally a hot person and when he goes through this he is freezing. Its almost like he's in a drugged state. He's a very intelligent man and for these 4 or 5 days you can barely understand a sentence that comes out of his mouth. He has very little use of his fingers and drops everything. He also has accidents like bowel and urine in his pants and has no memory that he did so. We have went to a psychologist and just a family doctor and they look at me like I'm crazy and they don't believe me. Please help
