Revision Flashcards
what is the difference between mania and hypomania
can generally function in hypomania
in mania cant usually function properly, can get psychotic symptoms
when does depression become treatment resistant
after 2 adequate trails of antidepressants with no response
how does ECT work
causes release of neurotransmitters - serotonin, dopamine, noradrenaline (why in can improve symptoms of parkinsons)
also causes growth in pathway between amygalada and prefrontal cortex (pathway involved in anxiety)
what is the drug of choice for generalised anxiety
SSRIs
is tremor a side effect of lithium
yes
what is formulation
how the patient gor ill considering genetics, psychological factors, precipitating factors
what are predisposing factors
genetics, early childhood, medical conditions, FMHx, things that happened in life before the illness started
what are precipitating factors
what caused the illness to start (stressor or other events that are related to the current symptoms- trauma, how you coped during change, personality development)
what are perpetuating factors
any conditions in the patient, family, community or larger system that exacerbate rather than solve the problem (relationship conflict, lack of education, financial stress, lack of employment)
what PD is DSH common in
emotionally unstable, bordline subtype
a MMSE below what suggests a cognitive problems
<24
what does MMSE test for
cognitive function (confusion)
what SE should you be cautious of with fluoxetine in young people
increased suicidal thoughts
what is clozapine and when is it used
an atypical antipsychotic- should only be given for treatment resistant schizophrenia after 2 antipsychotics have been tried (haloperidol, Prochlorperazine)
what are the side effets of clozapine
Can cause agranulocytosis (lower white blood cells to a level where they cant fight infection), need to be monitored with regular FBCs. Can cause weight gain, diabetes, drowsiness, dizziness, hypersalivation, myocarditis
what is the opposite of psychomotor retardation
psychomotor agitation
what is the inheritance of huntingtons
autosomal dominant
what are the psychiatric symptoms of huntingtons disease
depression compulsions suicidality aggression blunted affect (lack of affect/ no reactivity) psychosis anxiety
what are the cognitive symptoms of huntingons disease
decline in executive function
short and long term memory deficits
dementia- progressive decline in global cognition
what is included in executive function
planning, abstract thinking, cognitive flexibility, being able to use rules, initiation of actions, social communication
what are the motor symptoms of huntingtons disease
choreiform movements rigidity writhing movements gait disturbance problems chewing/ swallowing/ speaking
what is the genetics of huntingtons
CAG repeat encoding polyglutamine
genetic anticipation
toxic effect of glutamine on neuronal cells
40 repeats = 100% penetrance
is genetic anticipation worse via female or male transmission
CAG repeats multiply by more during male transmission
what is dementia
progressive decline in global cognitive function
what is implicit memory
eg carrying out tasks that are well practised
what inheritance of alzheimers
multifactoral
what suggests a familial form of dementia
more relatives affected
relatives affected at earlier age
unusual or atypical features
what is the lifetime risk of dementia
10%
25% if first degree relative affected
what percentage of UK population have BPAD
1%
what is the inheritance of BPAD
multifactorial
higher in monozygotic twins than in dizygotic
what delusions are common in psychotic depression
that you/ your organs are rotten
what drug is the primary treatment for schizophrenia
atypical antipsychotics- risperidone
when are atypical antipsychotics not used
lack of response, obesity/ FNHx of obesity - causes metabolic syndrome, parkinsons, heart disease
what is the primary mechanism of antipsychotics
block dopamine receptors
what are the two types of antipsychotic
typical and atypical
what symptoms are typical antipsychotics more likely to cause
extrapyramidal
what atypical antipsychotics are most likely to cause metabolic syndrome
olanzapine, risperidone, quetiapine, aripiprazole
what atypical antipsychotic should you use if you are worried about metabolic syndrome
aripiprazole
what is the treatment for schizophrenia
atypical antipsycotic, try two if first one has no effect
clozapine after trial of first if still no effect
what is clozapined used for
3rd line for treatment resistant schizophrenia
what do you need to monitor in clozapine
blood tests for agranulocytosis
cradiac function
bowel paralysis
what is the pharmacological treatment for acute agitation in psychosis
benzodiazepine (-epams)
then typical antipsychotic (haloperidol)
name two typical antipsychotics
haloperidol
chlorpromazine
what are depot antipsychotics
IM injection with extended release- helps in compliance issues
what is the treatment or OCD
CBT, exposure therapy, SSRI (setraline), 3rd line= tricylic
what is the mechanism of action of benzodiazepines
GABA agonist (main inhbitory neurotransmitter)
what are the risks of benzos
tolerance and addiction - dont get tolerance for SEs (resp depression, loose gag reflex - aspiration)
what are the withdrawal symptoms from benodiazepines
irritability, insomnia, dizziness, panic, nausea, sweating
which benzodiazepine has the ‘best’ half life
lorazepam- 12-20 hours, good for taking once a day
what are the treatments for GAD
1st line for GAD= CBT
2nd= SSRI (sertraline)
what is the treatment for panic disorder
exposure therapy
