PSYCHOSES/SCHIZOPRENIA

exhibit gross disturbances in their comprehension of reality, as evidenced by false perceptions (hallucinations) and false beliefs (delusions)

10
New cards

mesoCORTICAL pathway

  • Dopamine travels from the midbrain to the prefrontal lobe cortex

11
New cards

↓ neurotransmission of DA

Problem w/ mesoCORTICAL pathway

12
New cards
  • anhedonia,

  • alogia,

  • apathy

mesoCORTICAL pathway can result to (-) symptoms:

13
New cards

increase DA neurotransmission by giving atypical

Goal therapy for mesoCORTICAL pathway’s problem:

14
New cards

mesoLIMBIC pathway

Dopamine travels from the midbrain tegmental area to the nucleus accumbens

15
New cards

↑neurotransmission of dopamine

Problem w/ mesoLIMBIC pathway

16
New cards
  • agitation,

  • delusion,

  • disorganized thinking,

  • speech,

  • schizophrenia

mesoLIMBIC pathway can result to (+) symptoms:

17
New cards

decrease DA neurotransmission by giving typicals

Goal therapy for mesoLIMBIC pathway’s problem:

18
New cards

NIGROSTRIATAL PATHWAY

The pathway from the substantia nigra to the striatum (involved in the coordination of body movements)

19
New cards

Inhibition of this pathway causes the extrapyramidal side effects of antipsychotic drugs (typicals)

Problem w/ NIGROSTRIATAL PATHWAY

20
New cards

TUBEROINFUNDIBULAR PATHWAY

The pathway from the hypothalamus to the pituitary inhibits the release of prolactin.

21
New cards

HYPERPROLACTINEMIA

Inhibition of TUBEROINFUNDIBULAR PATHWAY pathway leads to:

33
New cards

Haloperidol

highest activity to block dopamine 2

34
New cards

ANTIPSYCHOTIC DRUGS

  • reduce psychotic symptoms and improve the behavior of schizophrenic patients

  • aka neuroleptic drugs because they suppress motor activity and emotional expression
