Described the interactions between mental health and physical health
Physical illness can precede mental illness – grief, loss, chronic pain, change in role/work. People with any chronic physical disease tend to feel more psychological distress than do healthy people. Poor physical health brings an increased risk of depression, as do the social and relationship problems that are very common among chronically ill patients.
Mental illness can precede physical illness – poor/maladaptive coping, self-harm, drug misuse. Depression linked to coronary heart disease, stroke, colorectal cancer, back pain, irritable bowel syndrome, multiple sclerosis, and possibly type 2 diabetes.
What is dysthymia?
A mood disorder consisting of the same cognitive and physical problems as in depression, with less severe but longer-lasting symptoms
Why might depression be more common in women?
Bio – Genetic predisposition, fluctuating hormone levels (think childbirth and menopause)
Psych – women ruminate more, men more likely to be stoic, angry or abuse substances. Women more invested in relationships.

What are the advantages and disadvantages of SSRIs compared to tricyclic antidepressants?

What is the difference between second person and third person auditory hallucinations?
Second order hallucinations are auditory hallucinations in which a voice appears to address the patient in the second person. For example the voice may be talking directly to the patient - "You are going to die" - or the voice may be telling the patient to do some action - "kill him". These types of auditory hallucinations are not diagnostic in the same way as third person auditory hallucinations, but the content of the hallucination, and the patient's reaction to it, may help in diagnosis
Third person hallucinations are auditory hallucinations in which patients hear voices talking about themselves, referring to them in the third person, for example "he is an evil person".

a) Third person auditory hallucinations
b) Visual and tactile hallucinations

(the clinician should not describe it as simply present or absent, but should report the patient's explanatory account descriptively)
