2. History
ā¢ Emil Kraepelin: This illness develops relatively early in
life, and its course is likely deteriorating and chronic;
deterioration reminded dementia (āDementia praecoxā), but
was not followed by any organic changes of the brain,
detectable at that time.
ā¢ Eugen Bleuler: He renamed Kraepelinās dementia praecox
as schizophrenia; he recognized the cognitive impairment in
this illness, which he named as a āsplittingā of mind.
ā¢ Kurt Schneider: He emphasized the role of psychotic
symptoms, as hallucinations, delusions and gave them the
privilege of āthe first rank symptomsā even in the concept of
the diagnosis of schizophrenia.

(haloperidol)
ā¢ ļ¼ control the positive symptoms very effectively
ā¢ ļ¼ side effects: extrapyramidal symptoms
ā¢ (chronic: tardive dyskinesia, parkinsonism, akathisia;
ā¢ acute: acute dystonia, neuroleptic malignant syndrome)
ā¢ ļ¼ high affinity for D2 dopamine receptors
32. ā¢ NEWER or ATYPICAL ANTIPSYCHOTICS (clozapine,
risperidone, olanzapine, ziprasidone, quietapine, sertindole)
ā¢ ļ¼ better at treating the negative symptoms
ā¢ ļ¼ milder motor side effects; but others (weight gain,
diabetes)
ā¢ ļ¼ they have affinity to multiple receptor systems (DARs,
5HTRs, a1, H1, m1/4)
conventional
antipsychotics
(classical
neuroleptics)
chlorpromazine, chlorprotixene, clopenthixole,
levopromazine, periciazine, thioridazine
droperidole, flupentixol, fluphenazine, fluspirilene,
haloperidol, melperone, oxyprothepine, penfluridol,
