This has been studied before with some success on improving cognitive function.
The idea is that atypical antipsychotics block the 5HT2A receptor thus improving cognition, and block the D2 receptor, thus inhibiting psychosis and mania, while the stimulants increase dopamine and thereby indirectly increase D1, D3, D4 and D5 activity, thus mitigating the cognitive issues seen in many psychiatric disorders including bipolar, schizophrenia, adhd, and so on.
I have tried this myself with 5mg abilify and 20mg ritalin although without much success
But has anyone of you found a combo that works?
