33.5 (lag 3 years for depression)
Most common comorbidity with depression

9%
14 times
% of person with first episode of depression will have mania episode within 10 years and its risk factors (5)
10%,
if illness earlier, switch was earlier (rate is 50%)
family history, antidepressant induced hypomania, hypersomnia, retarded phenomenology, psychotic depression and postpartum episode

32
2-4 episode
what is the longest duration of a depressive episode
if untreated
if untreated 6-13 months
recurrence rate of first episode
% of ppl will not have anymore episode, the rest will have within how long
% did not have a year free of episode
50% will not have any further episode, thr erest wil have it within 5 years
15% will not have a year free of episode
hows bipolar patient’s episode when compared to depression
2 times more
Terms for depression
1) remission
2) recover
3) relapse
4) recurrence
1) when patient achieved a state where no scales can detect meaningful measures of depression after 3 months of a treated episode
2) if the above more than 6 months
3) any repeat depression within 6 months
4) any depressive episode after 6 months of the initial episode
good prognostic indicators for depression (7)
1) mild episode
2) <1 episode of hospital admision
3) no psychotic symptoms
4) short hospital stay
5) history of solid friendship during adolescence
6) stable family functioning
7) no comorbid psychiatric disorder
8) good social functioning 5 years before illness
bad prognostic indicators for depression (7)
1) severity episode (suicidality and psychotic features)
2) persistent dysthymia
3) female sex
4) long previous episode
5) nvr marrying
6) long episode of illnes before seeking treatment
7) comorbid psychiatric and medical disorder
8) greater number of prior episode (3 or more)
9) partial remission at 3 months
NICE gudeline, points for management
1) first classify severity of the depresion
2) if there’s depression and anxiety, treat depression well
3) mild depression, review withnin 2 weeks, no need meds, can do CBT
4) SSRI first line
5) of moderate, to keep antidepressant for 6 months
6) if >2 episodes, need to keep for >2 years
7) if atypical use SSRI, then refer specialist
what study studies the continuation of antidepressants
Gedds and colleagues
include 410 patients
31 randomised trails
rate of relapse for 41% for those who stop antidepressant after an acute episode compared to 15%
wad is STAR*D
- similar world findings - 2/3 has comorbid physical disorder, 2/3 comorbid psych diagnosis, 40% has onset depression <18 years
- 4041 patient enrolled
- step 1 citalopram-> step 2 after 12 weeks to swucth to (buporion, sertaline, venlafaxine, or cognitive therapy or augment citalopram + buporion/buspirone, or citalopram with cognitive therapy
- step 3 switch to mirtazapine/nortriptyline, or augment step 2 treatment with lithium/thyroid medication
- step 4 MAOI, tranylcypromine, venla +mirta
- remission rates drop while relapse rate increases as patient to each level
results
-switch to class withnin SSRi is no diff then switch to outside SSRI
-no stat diff betwen switch options, or augment options , maoi with venla+ mirtaz
cumulative remission rate is 67%
gender diff with depression
Men report more suicidal ideation, 2-4 times more likely to be successful in their suicidal attempts, ,psychomotor agitation and substance use.
Women reported more suicidal attempts , more symptoms of anxiety and atypical depression, earlier onset, trend towards longer episodes
antidepressant -> increase suicide risk?
more in younger age group 18-24
Healy study shows in general suicide risk is 1.64 times
2015 study shows that antidepressany is not associated with increased risk of completed suicide
three antidepressant drugs that shows greater toxicity
TCA : dosulepin and doxepine more toxic than venlafaxine and mirtazapine more toxic than SSRI: citalopram
Wad are 5 things that might result in apparent resistance to antidepressant treatment (not true resistance)
5A
alcoholism, lack of adequate dosage, lack of adherance, axis 2 disorder, alternate diagnosis
Caliofornian rocket fuel is wad
combi of venla and mirtaz
what is mirtazepine
tetracyclic piperazinoazepine
what is agomelatine
5HT2C antagonist, a melatonergic agonist
ketamine
- a anaesthetic abd hallucinogenic drug
- blockade of glutametergic NMDA receptos and relative upregulation of AMPA receptors
- rapid improvemnt in mood
- KIV use ketamine as anesthetic agents
point prevalence for bipolar disorder
life time prevalence of bipolar 1 is % and bipolar 2 is %
1.5%
life time prevalence of bipolar 1 is 1%
life time prevalence of bipoalr of 1.1%
mean onset for bipolar 1 and 2?`
1 => 18.2
2=> 22
suicide rate of bipolar is how mnay times more than general population
15-18 times
prognosis of bipolar disorder
median time to recover
4-5 weeks
three types of course -> chronicity (with ot without full interepisode recovery), seasonality and repid cycling
% of people is predominatelt
1) depressed, risk factors (3)
2) manic, risk factors (3)
1) depressed : 1/3 -> more in bipolar 2, onset depresive, later onset, more suicide attempts, better with lamotrigine
2) manic: 1/4-> more bipolar 1, less seasonal, more substance use, onset often mania, earlier age
suicide rate in bipolar
% in depressive phase?
10-19%
80% happens in depressive phase
relapse rate of depression
50% in one year, >70% in 4 years
biggest predictor of relapse in bipolar
other 2 contributors
residual symptoms
-> sleep disruption, comorbidities (substance use disorder)
risk of antidepressant induced mania
risk for induced depression
1) previous antidepressant induced mania
2) bipolar family history
3) exposure to multiple antidepressant trails
4) initial illness beginning in adolesence or young adulthood
====
typical antipsychotics
differentiating unipolar depression with bipolar depression (4)
for unipolar depression:
1) more anxiety
2) more somatic complaints
3) less withdrawal
4) insomnia
5) less degree of retardation
6) less atypicality
rapid cycling is
when is ultra
ultra ultra rapid/ultradian cyclers
% in rapid cycling
4 episode per year (both depression and mania)
ultra is 4 episodes per month
ultra ultra rapid and ultradian cyclers: in in day
20%
risk factors of ultra rapid cycling
studied by whom
women(80%), earlier onset,
studied by STEP BD
hypothyroidism, substance misuse
will have more severe depression
drugs tat can cause secondary mania
more common in elderly
L dopa and corticosteriods
hypermania
evidence based treatment
: 1) treatment for acute de novo mania (3 points)
- antipsychotics fist line : haloperidole, olanzapine, quetiapine, rispedone
- dont give lamotrigine
- considered stop antidepressants
- adjunctive benzo such as clonazepam or lorazepam for agitation and insomnia
evidence based treatment
: 2) treatment for acute mania in known bipolar patients (3 points)
- increase dose of mood stabilisers
- check serum lithium consider high if compliance is good
- if already on lithioum, optimise lithium plasma level first then adding haloperidol/olanzapine/quetiapine/resperidone
- ECT for severely ill
evidence based treatment
: 3) treatment for bipolar depressive patients (3 points)
- psychological intervention
- first step: offer fluoxetine with olanzapine, or quetiapine alone
- second step offer lamotrigine
- antidepresants can be discontinue in 3-4 months as depressive episode in bipolar is shorter
evidence based treatment
: 4) treatment for maintainence (3 points)
BAP guidelines recommend: long term treatment after a single severe mania treatment (significant risk and adverse consequences)
-bipolar 1 with 2 or more acute apisode
bipolar two with sign functional impairment or risk
-first line lithium monotherapy - reduced risk of suicide in bipolar suicide
-other options: valporate (for mania), olanzapine (for mania), quetiapine, carbamazepine, lamotrigine (for depressive)
evidence based treatment
: 5) treatment for mixed episode (3 points)
treated as manic episodes
avoid antidepressants
high risk of suicide
-best evidence is valproate (better than lithium or placebo)
-atypical antipsychotic -> combination therapy
evidence based treatment
: 6) treatment for rapid cyclers
- avoid antidepressants
- treat hypothyroidism and substance misuse
- efects of lithium mwithdrawal to check
- erratic compliance
- to consider lithium, valporate, lamotrigine
what anticonvulsant should not be prescribe for bipolar
vigabatrin (can even cause visual field defects)
topimarate, phenytoin
incidence (definition) and in schizophrenia (3)
definition: the occurrence, rate, or frequency of a disease
- two times higher in urban settings
- 3-5 times more common in migrants
- winter/spring birth increase to a small extent
- male more than female 1.4:1
Prevalence (definition) and in schizophrenia (3)
- the percentage of a population that is affected with a particular disease at a given time.
- 0.4 life time prevalence,
- no diff in male and female
- higher rate in migrants and homeless people
wad is AESOP study?
shows that psychoses are more common in black and minority ethnic groups
high risk prediction studies shows: whoch kind of risk
genetic risk. functional impairment, higher levels of psychopathology
+/- substance use
Mean age of onset for GAD Panic disorder OCD Social phobia Specific phobia
Gender diff in above?
GAD 30 years Panic- 22-25 years OCD 20 years Social phobia - 15 years Specific phobia varies (blood around 5-6 years old)
Most are female expect for OCD where majority are boys but equal in adults men and women
