Is Abilify known to help with confusion or feeling as though you have a foggy head?

I was on this atypical antipsychotic for quite some time for Bipolar Disorder, taking 15 mgs daily for about 24 months and did not notice any improvement with, as you put it, "foggy brain", on the contrary and in general antipsychotics do not improve confusion/forgetfulness at least in people like myself who suffer from Bipolar Disorder, it may help most likely people who suffer from Schizophrenia, and of course everyone reacts differently to medications.
I am on 2 atypical antipsychotics now, Seroquel (quetiapine) and Zyprexa (olanzapine), I do not suffer from confusion/forgetfulness.

Now I did some research and I came across the following information:

"In summary, the greater dopamine receptor occupancy by aripiprazole was related with better performance in the working-memory task, suggesting that aripiprazole can enhance cognitive function in patients with schizophrenia whose dopaminergic function is defective."

"Clinical studies demonstrate that aripiprazole may be useful in the treatment of bipolar depression, major depressive disorder, treatment-resistant depression and possibly anxiety disorders. Clinical data also suggest that aripiprazole may have a lower adverse effect burden than the other atypical drugs."
