With major depression, there is a profound sadness or a sense of despair. The symptoms of major depression are defined as lasting at least two weeks, but usually they go on much longer. Other types of depression may have more subtle symptoms.
The American Midwifery Certification Board (AMCB) is the national certifying body for candidates in nurse-midwifery and midwifery who have received their graduate level education in programs accredited by the Accreditation Commission for Midwifery Education (ACME).
Board certification must be maintained by obtaining continuing nursing education credits. In the US, board certification is provided either through the American Nurses Credentialing Center (awards the FNP-BC credential) or through the American Association of Nurse Practitioners certification program (awards the NP-C credential).
