Further to policy 4.3.2, the expense authority may receive assistance from staff to fulfill his/her responsibilities.

Comorbidity: Addiction and Other Mental Illnesses. When two disorders or illnesses occur in the same person, simultaneously or sequentially, they are described as comorbid. Comorbidity also implies interactions between the illnesses that affect the course and prognosis of both.
Therefore, we sleep specialists now refer to the association as âcomorbid,â or existing alongside, rather than âsecondary,â which implies one condition causes the other. So someone might have insomnia comorbid with depression, but it does not necessarily mean that the depression caused the insomnia. The depression might have resulted from the insomnia, or be unrelated. Treating the âunderlyingâ diagnosis may not alleviate the insomnia.
