Theterm‘mentalhealthproblem’iscommonlyusedtodescribealltypesofemotionaldifficultiesfromtransientandtemporarystatesofdistress,ohenunderstandable,tosevereanduncommonmentalillness.Itisalsousedfrequentlytodescribelearningdifficulties,substancemisuseproblemsanddifficultiescopingwiththestressesandstrainsoflife.Itisthereforetoogeneralandtoonon-specifictobeofuseto themidwife.Thetermdoesnotdiscriminatebetweenseverityand needanddoesnothelpthemidwifedistinguishbetweenthoseconditionsthatshecanmanageand thosethatrequirespecialistafention.Forthisreason,inthischapter,theterm‘psychiatricdisorder’ispreferredasitcanbefurthercategorizedandthedifferenttypescanbedescribedaidingrecognitionandtheplanningofcare.

Thesewerepreviouslyknownas‘neuroticdisorders’.Theseincludenon-psychoticmildtomoderatedepressiveillness,mixedanxietyanddepression,anxietydisordersincludingphobicanxietystates,panicdisorder,obsessive–compulsivedisorderandpost-traumaticstressdisorder.

Overallpsychiatricdisordersareverycommoninthegeneralpopulation.TheGeneralHouseholdSurvey2000,asreportedbytheOfficeofNationalStatistics(ONS2002),revealsa prevalenceofover 20%ofthese disorders.RecentfiguresfromONS(2012)haveshownliflechangeinthistrendintheadultpopulationintheUK,reportingthatin2007,approximately1:6adultshadacommon mentaldisordersuchasanxietyordepression.
Theyarecommonerinwomenthaninmenwiththeexceptionofsubstancemisuseproblems.However,themajorityofpsychiatricdisordersinthecommunityaremildtomoderateconditions, particularlygeneralanxietyand depression. Mild to moderatedepressiveillnessandanxiety disordersareatleasttwiceascommoninwomenthaninmen,andareparticularlycommon inyoungwomenwith childrenundertheage of5.Themajorityofthesedisordersaremanaged inprimarycareand donotrequiretheafentionofspecialistpsychiatricservices.Mildtomoderatedepressiveillnessandanxietystatesrespondtopsychologicaltreatments.Despitethis,perhapsbecauseofshortageofsuchtreatments, prescriptionofantidepressantsiswidespreadinthecommunity,particularlyamongwomen.
Serious mentalillnesses are lesscommon.Both schizophreniaandbipolarillnessaffectapproximately1%ofthepopulation.Bipolarillnessaffectsmenandwomenequally.However,schizophrenia,particularlythemoreseverechronicforms,iscommoneramongmen.Theseconditionsrequiretheafentionofspecialistpsychiatricservicesandrequiremedicaltreatmentsaswellaspsychologicalcare.
