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.

3

What is dysthymia?

A mood disorder consisting of the same cognitive and physical problems as in depression, with less severe but longer-lasting symptoms

4

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.

Sociocultural – Women under more stress than men, women live lon ger – bereavement, loneliness, poor physical health. Women more likely to seek out a diagnosis of depression

5

• A prolonged or severe episode of mania

7

Action TCAs

8

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

9

10

What are core symptoms of schizophrenia according to the ICD10 classification?

What is a delusion and how can it be distinguished from normal experience?

As a pathology, it is distinct from a belief based on false or incomplete information, confabulation, dogma, illusion, or other effects of perception

12

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".

13

Which forms of hallucinations are characteristic of a) schizophrenia? b) organic disorders?

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

14

What are the components of insight? (How should it be recorded?)

Can be said to have three components:
- recognition that one has a mental illness
- compliance with treatment
- he ability to re-label unusual mental events (such as delusions and hallucinations) as pathological

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

Impaired insight is characteristic of psychosis and dementia, and is an important consideration in treatment planning and in assessing the capacity to consent to treatment.
