Psych Ix Flashcards
Diagnosis of complex ptsd
Core ptsd symptoms plus:
Negative self concept
Emotional dyregulation
Chronic interpersonal difficulties (don’t trust etc)
Diagnostic criteria for scizophrenia
two of the following:
delusions
hallucinations
disorganised speech
disorganised/catatonic behaviour
negative symptoms
at least 1 has to be delus./hallu/disorg speech
ongoing for 6 months- active phase at least 1 month
not another condition
Diagnostic criteria for OCD
Obsessions (something you think about so much that it affects your life) or
compulsions (ritualistic act which has to be performed unless something “bad” will happen)
must be present
Diagnostic criteria for panic disorder
Episodic panic, with no substantial triggers
Diagnostic criteria for PTSD
has to be for >1 month!
1) intrusive experience reminiscent of traumatic event
2) avoidance of anything reminiscent of the traumatic event
3) hyper-vigilance/hyper arousal, always on edge
what are the extrapyramidal side effects of antipyschotics (4)
dystonia- continuous spasms/muscle contractions
akathisia- restlessness
parkinsonism- rigidity, tremors, bradykinesia (slowing of movement)
tardive dyskinesia- irregular jerky movements, often lower face and distal extremeties
most typical antipyschotics end in …
zine
what receptors do antisyphotics act on
both typical and atypical act on d2 receptors, atypical also act on 5HT2A receptors
what do most atypical antipsychotics end in
pine or done
eg. quetipine or risperidone
what antipsychotic has a risk of neutropenia/agrnulocytosis
clozapine
which type of antipsychotic (atypical/typical) has worse metabolic side effects
atypical antipsychotics- weight gain, dyslipidemia, hyperglycemia
extrapyramidal side effects are less common in atypical or typical antipsychotics
atypical
which pathway is responsible for positive symptoms of schizophrenia
mesolimbic- high levels of dopamine in this pathway = positive symptoms eg. hallucinations
what pathway is responsible for negative symptoms in schizo
mesocortical- low levels dopamine occur in this pathway in schizo = negative symptoms eg social withdrawal and loss of motivation
what pathway causes parkinsonism in schizo when treated
nigostriatal- low levels of dopamine = parkinsonism, high levels = dyskinesia
what pathway in scizo is responsible for prolactinemia
tuberofundibular
typical anti-pyschotics are categorised into
high potentcy and low potentcy
give examples of low potentcy 1st generation anti-psychotics
most typical anti-psychotics (1st generation) are high potentcy
low potentcy- chlorpromazine
which atyical antipsychotic has the highest likliehood of causing extrapyramidal side effects
risperidone
which atypical antipsychotics have an increased affinity with h1 receptors and therefore cause…
clozapine, olanzapine, quetiapine- sedation and weight gain
which atypical antipsychotics have the highest affinity for 5-HT2C receptors and therefore cause…
clozapine, olanzapine
inc glucose, inc lipids (metabolic)
which atypical antipsychotics have a high affinity with a-1 receptors and therefore cause…
cloz and risperidone-= postural hypotension
for insomnia to be classed as chronic what is required.
must be present for at least 3 months and only needs to be present for 3 out of 7 nights in the week
blood result for purge-type bulimia
hypokalaemic metabolic acidosis
