Since Emil Kraepelin first coined the the term "Manic-depressive psychosis" in the 19th century,there has been a steady move within society to neutralise or attenuate such stark descriptions. Hence,we now have bipolar affective mood disorder. However, one must bear in mind that within psychiatry, hardly anything is written in tablets of stone. Certain symptoms,signs etc can be elicited in many other conditions ie, mania can be seen in transient alcoholic excitement...(mania a potue), certainly encountered in drug addiction. All such conditions can be pegged on a gradient from minimal to severe and all can be treated with some form of neuroleptic. However,thats about the level we have reached for surety of replies to a patient...."what causes it, can I be cured,how long will it last......." those answers have yet to be found. Several things however,dont change if the right diagnosis and treatments are to be applied. This condition is based on a persons reported experiences as well as observed states and behaviour. It is paramount that time,and an experienced listening ear is afforded. Sadly,......many practitioners for reasons best stated by them, do not have such time to give.As Kraepelin found, within the extreme manic state symptoms of delusions and or hallucinations can be elicited. I believe that at this point in todays world, the DVLA would be looking to suspend a qualified drivers licence. Only my humble opinion but I believe that anyone who,s professional role,judgement,skill and application bears the weight and safety of the general public, must be of sound mind and unclouded to the greatest degree of any substance blunting such ability.The hard part comes for those who have the task to assess such ability to allow a person under treatment to continue within a responsible career no matter the duration.
