No worries.

We could also look at post mortem neuroleptic induced morphological alterations in brain structure.

If you are referring to suicide risk, clozapine is the only antipsychotic with any proven effect on suicide rate.

The Effect of Antipsychotics on Cognition in Schizophrenia
http://www.cnsforum.com/magazine/focus/cognition_schizophrenia/
"Neuroleptics were associated with the reduction of psychotic symptoms of schizophrenia, but they did not demonstrate any significant impact on cognitive features of the disease (Sweeney et al., 1991)."
"Conventional antipsychotics, which primarily block D2 dopamine receptors, may demonstrate no effect (Berman et al., 1986) or minimal beneficial effect on cognitive functioning (Serper et al., 1994) or can even further impair cognitive functioning (Sweeney et al., 1991). Also, traditional antipsychotics cause extrapyramidal symptoms (EPS), which significantly decrease speed on cognitive tasks involving motor output and readiness to respond."
"Acute treatment with typical neuroleptics can result in a deterioration in some aspects of attention and motor behavior"
"neuroleptic drugs lack the ability to improve the various domains of cognitive function impaired in schizophrenia."
