which condition shows hypofrontality in cognitive tasks

A

schizophrenia

18
Q

diagnosis of schizophrenia

A

at least two of the following symptoms :

Delusions
Hallucinations
Disorganized speech
Disorganized or catatonic* behaviour
Negative symptoms (i.e. affective flattening, avolition…)

At least one of the symptoms must be the presence of delusions, hallucinations, or disorganized speech.

at least over 6 months of which active symptoms for a whole month

19

A

microglia

20
Q

which inflammatory markers can be raised in episodes of sch psychosis

A

tnf alpha
il6
crp

21
Q

Schizophrenia is associated with a dual dopaminergic imbalance: hyperactivity in the … and hypoactivity in the…

A

striatum (mesolimbic pathway –ventral striatum and also in the dorsal striatum),

mesocortical pathway – frontal cortex (to the cortex)

22
Q

do schizophrenia pts make more or less dopamine

A

more

23
Q

dopamine receptors are the main targets of schizophrenia drugs. Which receptors

A

D2/D3

24
Q

which was the first neuroleptic drug? what is the new name for neuroleptic

A

chlorpromazine
anti-psychotic

25
Q

which antipsychotics as first choice for sch

A

atypical (also called 2nd generation

26
Q

atypical (also called 2nd generation) examples

A

risperidone, olanzapine,** clozapine**, quetiapine,
paliperidone, aripiprazole

27
Q

all atypical antipsychotics have antagonist activity at which receptor other than dopamine

A

5HT2A

28
Q

Clozapine moa

A

Clozapine blocks D4 receptors with high affinity

29
Q

Aripiprazole moa

A

is a partial agonist at presynaptic D2 receptors (dampens them down)
but an antagonist at D2 postsynaptic receptors (blocks them) so double action

30
Q

typical (1st gen) antipsychotics examples

A

chlorpromazine, thioridazine,
fluphenazine, haloperidol, flupenthixol

31
Q

what are the extrapyridimal effects of antipsychotics and why

A

Extrapyramidal effects (EPS) (acute dystonias, parkinsonism,
tardive dyskinesia) ; approx. 60% D2 receptor occupancy required for
antipsychotic efficacy; if >80% D2 receptors are blocked, risk of EPS

32
Q

what is tardive dyskinesia

A

involuntary mvts in orofacial area

33
Q

involuntary mvts in orofacial area name

A

tardive dyskinesia

34
Q

Rise in prolactin due to antipsychotic can lead to

A

sexual dysfunction, galactorrhoea, amenorrhoea

35
Q

3 metabolic complications of atypical psychotics

A

Weight gain (atypicals)
Dyslipidemia (atypicals)
Type 2 diabetes (atypicals)

36
Q

clozapine and haloperidol have muscarinic affinity. what side effects result

A

dry mouth
dry eyes etc

37
Q

examples of drugs that can be depot antipsychotics

A

fluphenazine decanoate or haloperidol decanoate

38
Q

main side effects of typical antipsych

A

extra pyridimidal effects

39
Q

main side effects of atypical antipsych

A

metabolic complications

40
Q

what is Neuroleptic malignant syndrome
what is it associated with

A

mostly typical antipsychs
hyperpyrexia
muscle rigidity
tremor
confusion
autonomic instability
Occurs in up to 2-3% of patients taking antipsychotics (mostly typical drugs)

41
Q

30% schizophrenic patients do not respond to treatment
??? – drug of choice in drug resistance

what dangerous side effect

A

clozapine

agranulocytosis

42
Q

Schizophrenia is associated with decreased …transmission in the cortex

A

Schizophrenia is associated with decreased glutamatergic transmission
(hypoglutamatergic state in the cortex)
